Burnout during a long-term rehabilitation: comparing low burnout, high burnout - benefited, and high burnout - not benefited trajectories.
2009
To focus rehabilitation activities among burnout clients more effectively, it is important to investigate who benefits from burnout interventions. This study (N=85) aimed at identifying burnout trajectories in terms of benefit, that is, subgroups of clients who share similar mean levels and changes in burnout during a one-year rehabilitation intervention (17 days in total) with a six-month follow-up. After identifying the burnout trajectories, the relations of the trajectories with factors describing the clients, antecedents, and consequences of burnout during the one-year intervention were examined. Three burnout trajectories were identified by growth mixture modeling: (a) low burnout (n=3…
Effects of Adjacent Vehicles on Judgments of a Lead Car During Car Following.
2016
Objective: Two experiments were conducted to determine whether detection of the onset of a lead car’s deceleration and judgments of its time to contact (TTC) were affected by the presence of vehicles in lanes adjacent to the lead car. Background: In a previous study, TTC judgments of an approaching object by a stationary observer were influenced by an adjacent task-irrelevant approaching object. The implication is that vehicles in lanes adjacent to a lead car could influence a driver’s ability to detect the lead car’s deceleration and to make judgments of its TTC. Method: Displays simulated car-following scenes in which two vehicles in adjacent lanes were either present or absent. Participa…
Linking empowering leadership to safety participation in nuclear power plants: a structural equation model.
2012
Abstract Introduction Safety participation is of paramount importance in guaranteeing the safe running of nuclear power plants. Method The present study examined the effects of empowering leadership on safety participation. Results Based on a sample of 495 employees from two Spanish nuclear power plants, structural equation modeling showed that empowering leadership has a significant relationship with safety participation, which is mediated by collaborative team learning. In addition, the results revealed that the relationship between empowering leadership and collaborative learning is partially mediated by the promotion of dialogue and open communication. Conclusions The implications of th…
Is comfort food actually comforting for emotional eaters? A (moderated) mediation analysis
2019
Item does not contain fulltext An important but unreplicated earlier finding on comfort eating was that the association between food intake and immediate mood improvement appeared to be mediated by the palatability of the food, and that this effect was more pronounced for high than for low emotional eaters [26]. This has not yet been formally tested using mediation and moderated mediation analysis. We conducted these analyses using data from two experiments on non-obese female students (n = 29 and n = 74). Mood and eating satisfaction in Study 1, and mood, tastiness and emotional eating in Study 2 were all self-reported. In Study 1, using a sad mood induction procedure, emotional eaters ate…
Motion index: A new parameter to evaluate the diastole by M-Mode imaging
2009
AIM: Heart failure with normal left ventricle (LV) ejection fraction is commonly understood as diastolic heart failure because this expression implies the presence of LV diastolic dysfunction diagnosed by specific echocardiographic findings, such as slow LV relaxation and increased LV stiffness. In this work the authors propose a new parameter named Motion Index, which is measurable by M-Mode technique and it is likely linked to diastolic dysfunction. METHODS: A patient population composed by 134 subjects was enrolled. They all were in New York Heart Association (NYHA) functional class II. Echocardiogram carried out in all patients allowed the authors to distinguish 2 patient arms depending…
Lateralization of directional brain-heart information transfer during visual emotional elicitation
2019
Previous studies have characterized the physiological interactions between central nervous system (brain) and peripheral cardiovascular system (heart) during affective elicitation in healthy subjects; however, questions related to the directionality of this functional interplay have been gaining less attention from the scientific community. Here, we explore brain-heart interactions during visual emotional elicitation in healthy subjects using measures of Granger causality (GC), a widely used descriptor of causal influences between two dynamical systems. The proposed approach inferences causality between instantaneous cardiovagal dynamics estimated from inhomogeneous point-process models of…
Validation of the Maslach Burnout Inventory-Human Services Survey for Estimating Burnout in Dental Students.
2016
The aim of this study was to examine the validity and reliability of the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) as a tool for assessing the prevalence and level of burnout in dental students in Spanish universities. The survey was adapted from English to Spanish. A sample of 533 dental students from 15 Spanish universities and a control group of 188 medical students self-administered the survey online, using the Google Drive service. The test-retest reliability or reproducibility showed an Intraclass Correlation Coefficient of 0.95. The internal consistency of the survey was 0.922. Testing the construct validity showed two components with an eigenvalue greater than 1.5, w…
Enhanced rehabilitation guidance after arthroscopic capsulolabral repair of the shoulder : a randomized controlled trial
2020
Objective: To compare the effects of a 12-month home-based exercise program to usual care in patients after arthroscopic capsulolabral repair of the shoulder. Design: Randomized controlled trial. Setting: Outpatient physical and rehabilitation medicine clinic. Subjects: Forty-five patients (mean age: 35 years; standard deviation (SD): 10 years) who underwent arthroscopic capsulolabral repair due to labral lesion were randomized into an exercise group (EG) or a control group (CG). Intervention: The EG received a 12-month home-based additional exercise program with four physiotherapy follow-up visits, while the CG received standard postoperative exercise instructions. Main measures: Self-repo…
Stability of the upper neck during isometric neck exercises in rheumatoid arthritis patients with atlantoaxial disorders.
2008
To study the effect of isometric neck strength exercises on upper cervical stability in patients with rheumatoid arthritis (RA).Twenty patients with a mean (SD) age of 58 (9) years and duration of RA of 27 (10) years volunteered for the study. Lateral radiographs of the cervical spine were taken to measure the current atlantoaxial distance (AAD) in flexion and extension. Maximal isometric neck flexion and extension strength values were measured by a dynamometer. Thereafter, AADs were measured from radiographs taken at 80-90% resistance of maximal strength.According to the full flexion radiographs at baseline, the patients were classified into three groups: eight patients without anterior at…
Lumbar spine mobility in Marfan syndrome
1993
Low back pain symptoms and lumbar spine mobility were assessed by questionnaires and by clinical and radiological measurements in 32 patients with Marfan syndrome. Frequently occurring low back pain was reported by 19% of the patients, but the disability was slight in all of them. Flexion and extension mobility of the lumbar spine (L1-S1) assessed from radiographs was 59.9 degrees and 13.2 degrees, respectively. Mean lumbar angular mobility between flexion and extension radiographs was 7.4 degrees at L1-2, 13.2 degrees at L2-3, 16.0 degrees at L3-4, 19.3 degrees at L4-5 and 18.3 degrees at L5-S1. No correlation was found between the manual assessment of lumbar segmental instability and radi…
