Disentangling the effects of optimism and attributions on feelings of success

2014

Two experiments examined the effects of dispositional optimism and attributions on feelings of success in a performance setting. In Experiment 1, participants successfully solved three cognitive tasks and attributed the success either internally (i.e., to themselves) or externally (i.e., to a teammate). We found no effect of optimism, but a significant effect of the attribution: Internal attribution predicted an increase in feelings of success. In Experiment 2, we replicated the design and adopted an extreme groups approach in order to include the extremes of the optimism dimension. Only optimism affected feelings of success in this sample: Pessimistic participants showed higher increases i…

Self-Control in Daily Life

2016

In this daily diary study, we investigated the flexibility-enhancing effects of positive affect on the self-reported success of self-control strategies followed in daily life; 297 participants completed a 13-day daily diary that included measures of positive affect, desire, and habit strength as well as three self-control strategies (i.e., monitoring, distraction, and stimulus control). We found specific effects of positive affect on self-control strategies: Individuals with higher positive affect were most successful when following a strategy of distraction (e.g., thinking about something else), particularly when faced with strong tempting desires. These results reinforce the idea that po…

Heart rate variability and self-control–A meta-analysis

2016

We read the commentary on our meta-analysis with great interest and we greatly appreciate that the authors developed suggestions for further research on heart rate variability (HRV) and self-control. While we mostly support these suggestions, we believe that it is necessary to clarify some points raised with respect to our meta-analysis. The first point brought up by the authors of the commentary is the focus of our meta-analysis on HRV instead of vagal tone and the inclusion of studies using the standard deviation of RR intervals (SDNN). They argue that only vagal tone and HRV metrics reflecting vagal tone are expected to be linked to self-control according to both the Neurovisceral Integr…

Determinants of diet and physical Activity (DEDIPAC): a summary of findings

2017

The establishment of the Determinants of Diet and Physical Activity (DEDIPAC) Knowledge Hub, 2013 – 2016, was the first action taken by the ‘ Healthy Diet for a Healthy Life ’ European Joint Programming Initiative. DEDIPAC aimed to provide better insight into the determinants of diet, physical activity and sedentary behaviour across the life course, i.e. insight into the causes of the causes of important, non-commu nicable diseases across Europe and beyond. DEDIPAC was launched in late 2013, and delivered its final report in late 2016. In this paper we give an overview of what was achieved in terms of furthering measurement and monitoring, providing overviews of the state-of-the-art in the …

A round peg in a square hole: strategy-situation fit of intra- and interpersonal emotion regulation strategies and controllability

2019

Although the importance of contextual factors is often recognised, research on emotion regulation strategies (ERS) has mainly focused so far on the effectiveness of ERS across situations. In the present research, we tested the strategy-situation fit hypothesis, which does not assume general effectiveness of ERS but instead stresses the importance of the congruency between ERS and the contexts in which they are used. Using a longitudinal Ambulatory Assessment dataset (

Let There be Variance: Individual Differences in Consecutive Self–Control in A Laboratory Setting and Daily Life

2019

The large body of research used to support ego–depletion effects is currently faced with conceptual and replication issues, leading to doubt over the extent or even existence of the ego–depletion effect. By using within–person designs in a laboratory (Study 1; 187 participants) and an ambulatory assessment study (Study 2; 125 participants), we sought to clarify this ambiguity by investigating whether prominent situational variables (such as motivation and affect) or personality traits can help elucidate when ego depletion can be observed and when not. Although only marginal ego–depletion effects were found in both studies, these effects varied considerably between individuals, indicating t…

Heart rate variability and self-control—A meta-analysis

2015

Heart rate variability (HRV) has been suggested as a biological correlate of self-control. Whereas many studies found a relationship between HRV at rest and self-control, effect sizes vary substantially across studies in magnitude and direction. This meta-analysis evaluated the association between HRV at rest and self-control in laboratory tasks, with a particular focus on the identification of moderating factors (task characteristics, methodological aspects of HRV assessment, demographics). Overall, 24 articles with 26 studies and 132 effects (n=2317, mean age=22.44, range 18.4-57.8) were integrated (random effects model with robust variance estimation). We found a positive average effect …

The Effects of Self-Control on Glucose Utilization in a Hyperinsulinemic Euglycemic Glucose Clamp

2019

Abstract. Background. The glucose hypothesis of self-control posits that acts of self-control may draw upon glucose as a source of energy, leading to a decrease in blood glucose levels after exerting self-control, mirroring the temporary depletion of self-control, but supporting evidence is mixed and inconclusive. This might partly be due to using methods that are not suitable to reliably quantify glucose utilization. Aims. We aimed at examining whether self-control exertion leads to an increase in glucose utilization. Method. In a sample of N = 30 healthy participants (50% women, age 26.5 ± 3.5 years) we combined a hyperinsulinemic euglycemic glucose clamp (a well-established and validate…

Direct quantification of cell-free, circulating DNA from unpurified plasma.

2014

Cell-free DNA (cfDNA) in body tissues or fluids is extensively investigated in clinical medicine and other research fields. In this article we provide a direct quantitative real-time PCR (qPCR) as a sensitive tool for the measurement of cfDNA from plasma without previous DNA extraction, which is known to be accompanied by a reduction of DNA yield. The primer sets were designed to amplify a 90 and 222 bp multi-locus L1PA2 sequence. In the first module, cfDNA concentrations in unpurified plasma were compared to cfDNA concentrations in the eluate and the flow-through of the QIAamp DNA Blood Mini Kit and in the eluate of a phenol-chloroform isoamyl (PCI) based DNA extraction, to elucidate the D…

Music Listening and Stress in Daily Life—a Matter of Timing

2017

Purpose Despite increasing evidence suggesting that music listening in daily life has stress-reducing effects, studies mostly rely on subjective, retrospective data on music listening. Thus, the temporal dynamics underlying the stress-reducing effect of music listening remain unclear. Therefore, we aimed to examine the temporal dynamics of the associations between stress and music listening by assessing subjective and objective data on music in daily life. Design An exploratory Ambulatory Assessment study examining a total of 60 participants (37 women), aged 18 to 34 years (M = 22.4 years, SD = 3.5) was conducted. Methods For 1 week, participants answered questions on music listening and st…

Kontinuierliches Glukosemonitoring im Erleben des individuellen Patienten

2015

Patientensysteme zum kontinuierlichen Glukosemonitoring (CGM) liefern den Patienten wertvolle Information uber Glukoseverlaufe und -trends und haben prinzipiell das Potenzial, die Diabetes(selbst)behandlung deutlich zu verbessern. Zahlreiche empirische Befunde aus klinischen Studien belegen die Effektivitat von CGM. Allerdings zeigt sich auch, dass die Effektivitat von Patient zu Patient stark variieren kann und nicht alle Patienten die Informationen, die CGM liefert, optimal fur die Diabetesbehandlung nutzen. Ausgehend von einem systematischen Uberblick uber die bestehende Befundlage, werden in diesem Beitrag psychosoziale und Verhaltensfaktoren diskutiert, die mit beeinflussen konnen, ob …

PsychDT Working Group

2015

Background: Diabetes technology is a cornerstone of diabetes management in the 21st century, with advances in available devices over recent years playing a central role in the way that health care has progressed. Psychosocial interventions have been shown to have a positive impact on glycemic control, reduce psychological distress and reduce costs of health care. Addressing and improving psychosocial outcomes that complement biomedical improvements and looking to the future are crucial to enhance patient acceptance of artificial pancreas (AP) systems. Methods: To achieve closer collaboration and comparability across different AP research trials, a working group was established. Results: Exi…

Psychosocial Aspects of Continuous Glucose Monitoring

2016

Continuous glucose monitoring (CGM) systems provide people with diabetes with valuable real-time information on glucose trajectories and trends, thus offering opportunities for improving diabetes self-management. Ample evidence from clinical trials underscores CGM effectiveness for biomedical outcomes including HbA1C and hypoglycemia. However, interindividual variability in CGM uptake seems to be substantial: Neither do all individuals with diabetes adopt CGM readily in their diabetes self-management, nor do all of them benefit from CGM. In this article, we focus on CGM effects on quality of life and the potential role of psychosocial patient characteristics for determining the uptake and …

Increases of negative affect following daily hassles are not moderated by neuroticism: An ecological momentary assessment study

2020

The occurrence of daily hassles is associated with increased subsequent levels of negative affect. Neuroticism has been found to exacerbate this effect. So far, most research used single-item measures for the assessment of daily hassles or relied on daily diary studies. This study aimed to examine the interrelations of daily hassles, negative affect reactivity, and neuroticism in daily life employing an extensive inventory of daily hassles. Seventy participants (18-30 years; M = 23.9 years, 59% female) completed a 4-week smartphone-based ecological momentary assessment study reporting the occurrence and perceived strain of daily hassles as well as negative affect at five semi-random signals…

The power of status: What determines one's reactions to anger in a social situation?

2017

Abstract The present study examined how social status and gender determine anger expression and behavioral reactions toward experienced anger. In two experiments, anger was induced in a staged social interaction. Behavioral anger reactions were judged by observers. In Experiment 1 ( equal status condition ; N  = 110) participants were provoked by a confederate, in Experiment 2 ( low status condition ; N  = 116) participants were provoked by the experimenter. We found that participants expressed their anger to a lesser extent, were less resistant, and engaged in submissive behaviors if they had a lower status than the anger-target. As expected, gender had a moderating effect: While women's a…

Gamification and Behavior Change Techniques in Diabetes Self-Management Apps

2019

Background: Diabetes management apps may have positive effects on diabetes self-management. It remains unclear, however, which app features are particularly effective and encourage sustained app usage. Behavior change techniques (BCTs) and gamification are promising approaches to improve user engagement. However, little is known about the frequency BCTs and gamification techniques (GTs) are actually used. This app review aims to provide an overview of BCTs and GTs in current diabetes management apps. Methods: Google’s Play Store was searched for applications using a broad search strategy (keyword: “diabetes”). We limited our research to freely available apps. A total of 56 apps matched the …

Connecting Domains—Ecological Momentary Assessment in a Mobile Sensing Framework

2022

Ecological Momentary Assessment (EMA) is the state-of-the-art methodology to capture an individual’s experiences (e.g., feelings, thoughts, behaviors) in daily life in an ecologically valid way. In this chapter, we outline the prominent role of EMA within a broader mobile sensing framework connecting domains of data acquisition from a range of sensing sources. We particularly highlight the advantages of context-aware assessment strategies that link the assessment of experiences to specific sensing events or patterns. Finally, we discuss strategies that go beyond assessment to implement innovative Ecological Momentary Interventions in real-life.

Are glucose profiles well-controlled within the targets recommended by the international diabetes federation in type 2 diabetes? : a meta-analysis of…

2018

AIMS: To assess continuous glucose monitoring (CGM) derived intra-day glucose profiles using global guideline for type 2 diabetes recommended by the International Diabetes Federation (IDF). METHODS: The Cochrane Library, MEDLINE, PubMed, CINAHL and Science Direct were searched to identify observational studies reporting intra-day glucose profiles using CGM in people with type 2 diabetes on any anti-diabetes agents. Overall and subgroup analyses were conducted to summarise mean differences between reported glucose profiles (fasting glucose, pre-meal glucose, postprandial glucose and post-meal glucose spike/excursion) and the IDF targets. RESULTS: Twelve observational studies totalling 731 pe…

Experiences from a wearable-mobile acquisition system for ambulatory assessment of diet and activity

2017

Public health trends are currently monitored and diagnosed based on large studies that often rely on pen-and-paper data methods that tend to require a large collection campaign. With the pervasiveness of smart-phones and -watches throughout the general population, we argue in this paper that such devices and their built-in sensors can be used to capture such data more accurately with less of an effort. We present a system that targets a pan-European and harmonised architecture, using smartphones and wrist-worn activity loggers to enable the collection of data to estimate sedentary behavior and physical activity, plus the consumption of sugar-sweetened beverages. We report on a unified pilot…

Affective consequences of optimism and pessimism in the face of failure: Evidence of a moderation by attribution

2015

Abstract The present experiment set out to investigate the affective consequences of dispositional optimism and attribution in performance settings. Optimistic and pessimistic participants ( N  = 42 each) experienced failure at solving two cognitive tasks in an alleged team setting. The failure could either be attributed to themselves (internal condition) or a teammate (external condition). We found disordinal interactions of optimism and attribution on the feelings of success and feelings of failure. While the affective state of optimists deteriorated significantly if they attributed the failure internally compared to externally, pessimists were emotionally unaffected by the locus of attri…

The Differential Relations between Perceived Social Support and Rumination-Associated Goals

2013

In this study with N = 93 student participants, we employed a daily process approach to investigate sadness-associated rumination in daily life. Specifically, we examined whether the attainment of coping-related goals that people intend to achieve with their sadness-associated rumination were associated with changes in perceived social support. Moreover, we investigated the relations between sadness-related cognitive appraisals, goal pursuit and attainment, and ruminative process variables. Perceived social support was positively related to the attainment of resolution-focused goals, but not to understanding-focused goals, suggesting that social support is particularly associated with a fun…

Neuroticism may reflect emotional variability when correcting for the confound with the mean

2020

Kalokerinos et al. (1) demonstrate that emotional variability, as assessed via the SD, is not significantly associated with neuroticism once the confound with mean negative emotion is controlled for, r = 0.05. To control for this confound, the authors use the relative SD (RSD), which mathematically corrects for the nonlinear dependency between the SD and the mean (2). The authors prefer the RSD over including the SD and the mean of negative emotions in a model, given the nonlinearity of their association. While we agree that the RSD is an important addition to the field, we argue that including the mean of emotions is still necessary when examining the association between neuroticism and em…

Psychological insulin resistance in geriatric patients with diabetes mellitus.

2013

To determine the extent to which geriatric patients with diabetes mellitus experience psychological insulin resistance (PIR).A total of 67 unselected geriatric patients with diabetes (mean age 82.8±6.7 years, diabetes duration 12.2 [0.04-47.2] years, 70.1% female) were recruited in a geriatric care center of a university hospital. A comprehensive geriatric assessment (CGA) was performed including WHO-5, Hospital Anxiety and Depression Scale (HADS), Mini Mental State Examination (MMSE) and Barthel-Index. We assessed PIR using the Barriers of Insulin Treatment Questionnaire (BIT) and the Insulin Treatment Appraisal Scale in a face-to-face interview.Insulin-naïve patients (INP) showed higher P…

The Limits of Ego Depletion

2019

Abstract. Evidence on the existence of the ego depletion phenomena as well as the size of the effects and potential moderators and mediators are ambiguous. Building on a crossover design that enables superior statistical power within a single study, we investigated the robustness of the ego depletion effect between and within subjects and moderating and mediating influences of the ego depletion manipulation checks. Our results, based on a sample of 187 participants, demonstrated that (a) the between- and within-subject ego depletion effects only had negligible effect sizes and that there was (b) large interindividual variability that (c) could not be explained by differences in ego depleti…

Glucose metabolism and self-regulation — Is insulin resistance a valid proxy of self-control?

2016

Abstract Glucose metabolism has been suggested as an underlying biological factor of self-control stimulating a range of studies exploring the associations between glucose and self-control. Research on interindividual trait-like differences in glucose metabolism and self-control is sparse, as most previous research has focused on associations between state self-control performance and momentary glucose levels. In two experiments in healthy participants (n = 60, mean age 35.2 ± 13.9, 58% women; n = 103, mean age 25.8 ± 6.3, 67% women) consisting of a baseline assessment and a laboratory session, we examined whether trait markers of glucose metabolism (fasting glucose levels, oral glucose tol…

Continuous Glucose Monitoring in Type 1 Diabetes

2016

Background: Continuous glucose monitoring (CGM) patient systems have been shown to improve diabetes self-treatment when used consistently. The meaningful integration of this technology into everyday life, however, can vary greatly among CGM users and not all people with diabetes use CGM to its full potential. To address this issue, the study pursued 2 aims: first, to identify patient characteristics that underlie the acceptance of CGM in people with type 1 diabetes and, second, to examine the effects of different levels of experience with CGM use. Methods: Guided by a model based on the technology acceptance model (TAM), structural equation modeling (SEM) was employed to model the patient c…

Prognosis of Patients Listed for a Heart Transplant During the Pretransplant Period: Does Diabetes Matter?

2013

Whether patients with advanced heart failure and diabetes mellitus (DM) should be listed for heart transplantation (HTx) remains controversial due to conflicting findings regarding their post-HTx survival (1–3). We studied HTx candidates with and without DM during the pre-HTx period, examining multiple waiting list outcomes. Patients were enrolled in the Waiting for a New Heart Study, a multisite observational study of 318 adult (≥18 years of age) patients (aged 53 ± 11 years; 18% female) who were newly listed for HTx with Eurotransplant between April 2005 and December 2006 (4). Informed consent and ethics approval were obtained (4). Characteristics at the time of listing included age, DM, …

Correlation between cell free DNA levels and medical evaluation of disease progression in systemic lupus erythematosus patients

2014

High levels of cell free DNA (cfDNA) in human blood plasma have been described in patients with autoimmune diseases. The aim of this study was to determine the levels of cfDNA in systemic lupus erythematosus (SLE) patients and to assess fluctuations of cfDNA concentrations compared to the course of disease progression under standard treatment. Therefore, nuclear cfDNA concentrations in plasma were measured in 59 SLE patients and 59 healthy controls. Follow-up blood plasma was collected from 27 of the 59 SLE patients. Patients were characterised by clinical parameters (antinuclear antibodies (ANA), anti-dsDNA-antibodies, C3, C4, and CRP), SLE disease activity index (SLEDAI) and medical thera…

Curb your neuroticism – Mindfulness mediates the link between neuroticism and subjective well-being

2015

Abstract Recent research has shown that mindfulness moderates the negative emotional reactivity associated with neuroticism. In two studies, we investigated how neuroticism and mindfulness are associated with subjective well-being (SWB), assuming a moderated mediation. In Study 1, 147 participants (74.2% female, M  = 34.3 years, SD  = 11.9) completed an online survey. Mindfulness partially mediated but did not moderate the relationship between neuroticism and SWB, indicating that low levels of mindfulness were partially accountable for lower SWB in individuals high in neuroticism. In Study 2, 108 participants (80.6% female, M  = 25.2 years, SD  = 6.6) completed daily diaries for 6 days. We …

Like clouds in a windy sky : mindfulness training reduces negative affect reactivity in daily life in a randomized controlled trial

2020

While prior research has found mindfulness to be linked with emotional responses to events, less is known about this effect in a non-clinical sample. Even less is known regarding the mechanisms of the underlying processes: It is unclear whether participants who exhibit increased acceptance show decreased emotional reactivity (i.e., lower affective responses towards events overall) or a speedier emotional recovery (i.e., subsequent decrease in negative affect) due to adopting an accepting stance. To address these questions, we re-analysed two Ambulatory Assessment data sets. The first (NStudy1 = 125) was a 6-week randomized controlled trial (including a 40-day ambulatory assessment); the sec…

Positive Beliefs about Rumination Are Associated with Ruminative Thinking and Affect in Daily Life: Evidence for a Metacognitive View on Depression

2013

Background: Self-regulatory executive function theory (Wells and Matthews, 1994; Wells, 2008) stresses the role of metacognitions in the development of emotional disorders. Within this metacognitive model, positive beliefs about ruminative thinking are thought to be a risk factor for engaging in rumination and subsequently for depression. However, most of the existing research relies on retrospective self-report trait measures. Aims: The aim of the present study was to examine the theory's predictions with an Ecological Momentary Assessment approach capturing rumination as it occurs in daily life. Method: Non-clinical participants (N = 93) were equipped with electronic diaries and completed…

Adaptive modes of rumination: the role of subjective anger.

2015

Rumination has been demonstrated to have negative consequences on affect, behaviour, and physiological markers. Recent studies, however, suggest that distinct "modes" of anger-associated rumination may lead to several positive consequences. Previous research primarily used recall procedures of anger episodes to elicit anger. By contrast, the present study focused on the effect of subjective anger on the process of rumination and tested its effects in a "staged" social interaction where a confederate provoked participants. Subsequently, participants engaged in rumination about the anger-eliciting event either in an abstract-distanced or a concrete-immersed rumination mode. Results showed an …

Setbacks in Self-Control: Failing Not Mere Resisting Impairs Subsequent Self-Control

2020

Research on ego depletion has often relied on the dual-task setting employing short tasks with low ecological validity. The comparatively few studies on ego depletion in daily life so far used diverging operationalization and yielded ambiguous results. We argue that fundamental research on short-term self-control limitations can benefit from research on the limit violation effect, which highlights the danger to self-control when setbacks are attributed to internal causes. To test the role of setbacks and compare different ego depletion operationalizations in daily life, we used data from two ambulatory assessment studies ( N = 125 and 205). No consistent ego depletion effects were observed…

Fear of hypoglycemia in patients with type 2 diabetes: The role of interoceptive accuracy and prior episodes of hypoglycemia.

2017

Abstract Objective Fear of hypoglycemia (FoH) is a limiting factor for diabetes self-management and can have detrimental effects on quality of life. However, relatively little is known about its underlying mechanisms. In line with findings on patients with anxiety disorders, we hypothesized that interoceptive accuracy (IA) might be positively linked to FoH in patients with type 2 diabetes (T2DM). Methods 133 patients with T2DM were screened according to the extreme quartiles of the Hypoglycemia Fear Survey worry subscale (HFS-W). Overall, 66 participants (HFS-W   17) were included in the present study. Participants completed questionnaires on sociodemographic and diabetes-related measures. …

Examining five pathways on how self-control is associated with emotion regulation and affective well-being in daily life.

2020

OBJECTIVE Self-control is positively connected to well-being, but less is known about what, on the mechanistic level, explains this association. We hypothesized five pathways how this connection could be explained by emotion regulation, that is, by facilitating (a) strategy effectiveness, (b), adaptive strategy selection, (c) situation selection, (d) strategy variability, or (e) social sharing. METHOD To explore these pathways, we integrated two ambulatory assessment data sets (N = 250 participants, N = 22,796 observations) that included assessments of participants' emotions and their emotion regulation efforts. RESULTS We found that self-control was positively associated with affective wel…

2019

We applaud Umpierrez and Klonoff (1) for reviewing the evidence on the application of insulin pump therapy (continuous subcutaneous glucose infusion [CSII]) and continuous glucose monitoring in inpatient settings. However, we missed a dedicated section about the patients’ perspective and experiences concerning insulin pump use in hospitals. In a qualitative survey conducted in Germany, elderly patients with type 1 diabetes (≥65 years, n = 136) and health care professionals (HCP, n = 96) were asked about their wishes, concerns, and needs related to CSII (2). The 290 responses (165 patients; 125 HCPs) were classified into three categories. First were positive experiences (patients n = 17; HCP…

Ambulatory assessment as a means of longitudinal phenotypes characterization in psychiatric disorders

2014

Abstract Ambulatory Assessment (AA) comprises the use of in-field methods to assess individuals’ behavior, physiology, and the experience as they unfold in naturalistic settings. We propose that AA is favorable for the investigation of gene–environment interactions and for the search for endophenotypes, being able to assess the experienced environment and to track basic regulatory processes, such as stress reactivity, affective instability, and reward experience, which are potential common factors that underlie psychiatric disorders. In this article, we (a) first describe briefly the rationale of AA and summarize the key advantages of the approach, (b) highlight within-subject regulatory pr…

Aim To identify key psychosocial research in the domain of diabetes technology. Results Four trajectories of psychosocial diabetes technology research are identified that characterize research over the past 25 years. Key evidence is reviewed on psychosocial outcomes of technology use as well as psychosocial barriers and facilitating conditions of diabetes technology uptake. Psychosocial interventions that address modifiable barriers and psychosocial factors have proven to be effective in improving glycaemic and self-reported outcomes in diabetes technology users. Conclusions Psychosocial diabetes technology research is essential for designing interventions and education programmes targeting…

Experiencing anger in a social interaction: The role of personality

2018

Abstract Although prior research has shown a relationship between the Big Five personality factors and trait anger, evidence that links these personality traits to the experience of state anger is rare. The current study investigated the effect of the Big Five personality traits on the state anger experience after a provocation in a staged social interaction and how status differences moderate these personality effects in an academic sample. In the equal status condition (N = 131, 56% female, aged 18 to 37) participants were provoked by a confederate; in the low status condition (N = 125, 55% female, aged 18 to 51) anger was instead provoked by the experimenter. In both conditions, individu…

2014

To address major societal challenges and enhance cooperation in research across Europe, the European Commission has initiated and facilitated ‘joint programming’. Joint programming is a process by which Member States engage in defining, developing and implementing a common strategic research agenda, based on a shared vision of how to address major societal challenges that no Member State is capable of resolving independently. Setting up a Joint Programming Initiative (JPI) should also contribute to avoiding unnecessary overlap and repetition of research, and enable and enhance the development and use of standardised research methods, procedures and data management.

How mindfulness shapes the situational use of emotion regulation strategies in daily life.

2020

Mindfulness is associated with a wide range of beneficial outcomes such as well-being. However, less is known about the mechanisms underlying these benefits. Some researchers suggest that the benefits could be driven by emotion regulation, either by improving the effectiveness of emotion regulation or by lessening the need for effortful emotion regulation. By using two longitudinal Ambulatory Assessment data sets (

Positive affect and self-control: attention to self-control demands mediates the influence of positive affect on consecutive self-control.

2013

Positive affect (PA) can either improve or impair self-control performance, depending on whether two tasks are dissimilar, and thus require flexible releasing and switching, or similar, which requires stable maintenance. The present study suggests that this effect is mediated by attentional shifts. The authors found that participants under PA, who performed on two dissimilar tasks and had to switch to a new response dimension, were less attentive to distracting information compared to neutral affect (NE), leading to better performance. In contrast, participants under PA who did not have to switch, were more attentive to distracting information compared to participants under NE. These findin…

Patient-Reported Outcomes and Continuous Glucose Monitoring: Can We Do Better With Artificial Pancreas Devices?

2015

Patient-reported outcomes (PROs) assess a person’s experience, feelings, and thoughts about both their condition and its treatment. PROs are able to contribute to a benefit assessment of new medical products by introducing the patients’ subjective evaluation of medical products into the evaluation process. Thus, PROs are also the cornerstone of medical product development for understanding patients’ perceptions on medical products and/or its benefit assessment. In the past 15 years, PROs were also evaluated in most clinical trials performed with continuous glucose monitoring systems. However, in its recent evaluation of such trials, the German Institute for Quality and Efficiency in Health …

Assessment of Microstressors in Adults: Questionnaire Development and Ecological Validation of the Mainz Inventory of Microstressors

2020

Background Many existing scales for microstressor assessment do not differentiate between objective (ie, observable) stressor events and stressful cognitions or concerns. They often mix items assessing objective stressor events with items measuring other aspects of stress, such as perceived stressor severity, the evoked stress reaction, or further consequences on health, which may result in spurious associations in studies that include other questionnaires that measure such constructs. Most scales were developed several decades ago; therefore, modern life stressors may not be represented. Ecological momentary assessment (EMA) allows for sampling of current behaviors and experiences in real…

Understanding the limits of self-control: Positive affect moderates the impact of task switching on consecutive self-control performance

2013

Performing consecutive self-control tasks typically leads to deterioration in self-control performance. This effect can be explained within the strength model of self-control or within a cognitive control perspective. Both theoretical frameworks differ in their predictions with regard to the impact of affect and task characteristics on self-control deterioration within a two-task paradigm. Whereas the strength model predicts decrements in self-control performance whenever both tasks require a limited resource, under a cognitive control perspective, decrements should only occur when people switch to a different response conflict in the second task. Moreover, only the cognitive control model …

Focus group study to identify the central facets of fear of hypoglycaemia in people with Type 2 diabetes mellitus.

2017

Aims To determine key worries about hypoglycaemia among insulin-using adults with Type 2 diabetes using a focus group approach. Methods Thirteen focus groups were conducted in three diabetes outpatient care units and one peer support group was set up, in Germany. A total of 64 insulin-dependent adults with Type 2 diabetes (36.5% women, mean age 65.2 ± 11.0 years) discussed their worries about hypoglycaemia. The qualitative results were assigned into thematic categories using a bottom-up coding procedure. Participants completed the Hypoglycaemia Fear Survey and demographic measures were recorded. The results of the Hypoglycaemia Fear Survey were contrasted with the focus group findings to ev…

Intervention studies to foster resilience – A systematic review and proposal for a resilience framework in future intervention studies

2017

Psychological resilience refers to the phenomenon that many people are able to adapt to the challenges of life and maintain mental health despite exposure to adversity. This has stimulated research on training programs to foster psychological resilience. We evaluated concepts, methods and designs of 43 randomized controlled trials published between 1979 and 2014 which assessed the efficacy of such training programs and propose standards for future intervention research based on recent developments in the field. We found that concepts, methods and designs in current resilience intervention studies are of limited use to properly assess efficacy of interventions to foster resilience. Major pro…

The Role of Self-Control and the Presence of Enactment Models on Sugar-Sweetened Beverage Consumption: A Pilot Study

2019

The objective of the present research was to investigate associations of dispositional and momentary self-control and the presence of other individuals consuming SSBs with the consumption frequency of sugar-sweetened beverages (SSBs) in a multi-country pilot study. We conducted an Ambulatory Assessment in which 75 university students (52 females) from four study sites carried smartphones and received prompts six times a day in their everyday environments to capture information regarding momentary self-control and the presence of other individuals consuming SSBs. Multilevel models revealed a statistically significant negative association between dispositional self-control and SSB consumption…

The effects of computer-based mindfulness training on Self-control and Mindfulness within Ambulatorily assessed network Systems across Health-related…

2016

Background Self-control is an important ability in everyday life, showing associations with health-related outcomes. The aim of the Self-control and Mindfulness within Ambulatorily assessed network Systems across Health-related domains (SMASH) study is twofold: first, the effectiveness of a computer-based mindfulness training will be evaluated in a randomized controlled trial. Second, the SMASH study implements a novel network approach in order to investigate complex temporal interdependencies of self-control networks across several domains. Methods The SMASH study is a two-armed, 6-week, non-blinded randomized controlled trial that combines seven weekly laboratory meetings and 40 days of e…

Population-based validation of a German version of the Brief Resilience Scale.

2017

Smith and colleagues developed the Brief Resilience Scale (BRS) to assess the individual ability to recover from stress despite significant adversity. This study aimed to validate the German version of the BRS. We used data from a population-based (sample 1: n = 1.481) and a representative (sample 2: n = 1.128) sample of participants from the German general population (age ≥ 18) to assess reliability and validity. Confirmatory factor analyses (CFA) were conducted to compare one- and two-factorial models from previous studies with a method-factor model which especially accounts for the wording of the items. Reliability was analyzed. Convergent validity was measured by correlating BRS scores …
