Dopamine D2/D3 receptor availability and venturesomeness.
2011
The construct of impulsivity is considered as a major trait of personality. There is growing evidence that the mesolimbic dopamine system plays an important role in the modulation of impulsivity and venturesomeness, the two key components within the impulsivity-construct. The aim of the present study was to explore an association between trait impulsivity measured with self-assessment and the dopaminergic neurotransmission as measured by positron emission tomography (PET) in a cohort of healthy male subjects. In vivo D2/D3 receptor availability was determined with [(18)F]fallypride PET in 18 non-smoking healthy subjects. The character trait impulsivity was measured using the Impulsiveness-V…
Hypogonadism-related symptoms: development and evaluation of an empirically derived self-rating instrument (HRS ‘Hypogonadism Related Symptom Scale’)
2009
While self-report screening instruments are highly sensitive to hypogonadism in the ageing male, they have lacked specificity as evidenced by low or absent correlations with testosterone. The purpose of this paper was to develop an economical and specific screening instrument for identifying hypogonadal ageing men. Based on a comprehensive study of physical, somatoform and affective complaints, sexual behaviour and function and hormonal parameters of 263 outpatients aged 40 years and above (M = 56.2; 40-84 years) recruited from six andrological outpatient departments in Germany, we identified those items correlating significantly with testosterone. By factor analyses, five factors were iden…
Enabling resources in people with dementia: a qualitative study about nurses’ strategies that may support a sense of coherence in people with dementia
2015
Aims and objectives To explore nurses’ strategies that may support the sense of coherence in people with dementia. Background People with dementia are often described as people with no resources, people who need support from family or from healthcare personnel to function in everyday life. Despite the disease, some people still have the resources needed to cope well with parts of their lives and experience coherence. To date, no research has explored any nurses’ strategies that may support the sense of coherence in people with dementia. Design The design of the study is qualitative and exploratory. Methods Data were collected by participant observation and focus group interviews. Sixteen re…
How does illness severity influence depression, health satisfaction and life satisfaction in patients with cardiovascular disease? The mediating role…
2013
Numerous empirical studies have investigated the relationships between cardiovascular diseases (CVD) and patients' psychological well-being, with a focus almost exclusively on its dark side. Very little is known on the impact of illness severity on both negative and positive indicators of patients' well-being, as well as on the psychosocial variables that may mediate this association. Aim of the study was to investigate the impact of illness severity on depression as well as on health satisfaction and life satisfaction of patients undergoing a cardiovascular rehabilitation. It also aimed at testing the mediation of illness perception and self-efficacy beliefs in managing cardiac risk factor…
Psychophysiological and vocal measures in the detection of guilty knowledge.
2004
The Guilty Knowledge Test (GKT) and its variant, the Guilty Actions Test (GAT), are both psychophysiological questioning techniques aiming to detect guilty knowledge of suspects or witnesses in criminal and forensic cases. Using a GAT, this study examined the validity of various physiological and vocal measures for the identification of guilty and innocent participants in a mock crime paradigm. Electrodermal, respiratory, and cardiovascular measures successfully differentiated between the two groups. A logistic regression model based on these variables achieved hit rates of above 90%. In contrast to these results, the vocal measures provided by the computerized voice stress analysis system …
Association between nutritional values of hays fed to horses and sensory properties as perceived by human sight, touch and smell
2019
International audience; Although hay is the foundation of most equine diets, horse owners rarely ask for biochemical analysis and the routine practice is to choose hay based on its 'perceived' nutritional value. The present study aimed at exploring the relationship between sensory properties as perceived by sight, touch and smell, and the nutritional value of hay measured by biochemical analysis using a 'free sorting task' method. Fifty-four non-expert participants were asked individually to: (1) observe 21 hays samples, (2) group together hays that they perceived as similar for each of the three modalities (hay appearance, odour or texture) and (3) characterize each formed group with a max…
Family violence and mental health in a sample of Finnish health care professionals : the mediating role of perceived sleep quality
2019
Background Family violence (FV) is a prevalent health issue around the world and health care services have an important role in both recognizing and treating the consequences of violence. However, FV experiences among health care professionals themselves have not been investigated much. We also lack specific knowledge on the associations between FV and mental health. Aim The purpose of the study was to investigate the prevalence and effects of FV in a sample of Finnish health care professionals. In addition to analysing direct connections between different types of FV and mental health, the mediating effect of sleep quality was also taken into account. Methods The study followed a cross‐sec…
Physical Activity, Sleep, and Symptoms of Depression in Adults - Testing for Mediation
2019
Abstract Purpose: Physical activity, sleep problems, and symptoms of depression contribute to overall well-being. The factors are reciprocally associated, but the nature of these associations remains unclear. The present study examined whether sleep problems mediated the association between physical activity and depressive symptoms. Methods: The eligible population (n = 3596) consisted of adults from the ongoing, population-based Cardiovascular Risk in Young Finns Study started in 1980. Participants’ leisure-time physical activity was assessed with physical activity index (2007) and sleep problems with Jenkins’ Sleep Questionnaire in 2007 and 2011. Depressive symptoms were measured using mo…
Sleep phenotypes of intellectual disability: a polysomnographic evaluation in subjects with Down syndrome and Fragile X syndrome
2008
Abstract Objective To analyze sleep architecture and NREM sleep alterations by means of the Cyclic Alternating Pattern (CAP) in children with Down syndrome (DS) and Fragile-X syndrome (fraX), the two most common causes of inherited mental retardation, in order to find out eventual alterations of their sleep microstructure related to their mental retardation phenotypes. Methods Fourteen patients affected by fraX (mean age 13.1 years) and 9 affected by Down syndrome (mean age 13.8 years) and 26 age-matched normal controls were included. All subjects underwent overnight polysomnography in the sleep laboratory, after one adaptation night and their sleep architecture and CAP were visually scored…
A scale on beliefs about children's adjustment in same-sex families: reliability and validity.
2012
In this study, we developed a new instrument named Scale Beliefs about Children's Adjustment on Same-Sex Families (SBCASSF). The scale was developed to assess of the adults' beliefs about negative impacts on children who are raised by same-sex parents. An initial pool of 95 items was generated by the authors based on a review of the literature on homophobia and feedback from several focus groups. Research findings, based on a sample of 212 university students (mean age 22 years, SD = 8.28), supported the reliability and validity of the scale. The final versions of the SBCASSF included items reflecting the following two factors: individual opposition (α = .87) and normative opposition (α = .…
