Sexual Assault and the Association With Health, Quality of Life, and Self-Efficacy in the General Norwegian Population

The lifetime prevalence of sexual assault was examined in a representative sample of the general Norwegian adult population (n = 1,792), in addition to the association between sexual assault and health, quality of life, and general self-efficacy. Respondents completed questionnaires assessing these factors. Overall, 6.7% (n = 120) of the respondents (10.9% of women and 1.9% of men) reported an experience of sexual assault. Respondents in the sexual assault group reported significantly worse mental and physical health as well as poorer quality of life and lower self-efficacy, compared with those without sexual assault experience. The most prevalent mental problems in the sexual assault group were depression (61.7%), sleep problems (58.3%), eating disorders (26.7%), and posttraumatic stress disorder symptoms at a clinical level (25.0%). The most prevalent physical problems were chronic pain (47.5%) and musculoskeletal disease (30.8%). The proportions of physical and mental health problems were not significantly different between male and female victims. Results indicated that having experienced sexual assault during one's life appears to be associated with lifetime occurrence of multiple health problems for both genders and reduces a person's perceived general self-efficacy and quality of life.

Participant Characteristics Associated with Changes in Mental Health in a Trial of Behavioural Weight Management Programmes: Secondary Analysis of the WRAP Trial

INTRODUCTION

On average, aspects of mental health improve following behavioural weight management programmes, yet this is not the case for all participants. It is important to identify those at risk of harm to provide more effective psychological support. We aimed to identify participant characteristics associated with changes in depression and anxiety in participants of a behavioural weight management programme.

METHODS

In the Weight loss Referrals for Adults in Primary care trial, 1,267 adults with body mass index ≥28 kg/m2 were randomized to brief intervention, or WW (formerly weight watchers) for 12-weeks or 52-weeks and followed for 5 years. We used linear and multinomial regression to explore the association between participant characteristics and changes in depression and anxiety (measured by the hospital anxiety and depression scale). Where possible, the impact of missing data was investigated using multiple imputation.

RESULTS

Higher baseline anxiety was associated with decreases in anxiety symptoms and increases in depression symptoms from baseline to follow-up. Higher baseline depression was associated with decreases in depression symptoms and increases in anxiety symptoms from baseline to follow-up. The magnitude of the associations was small. No further characteristics were consistently associated with changes in mental health.

DISCUSSION

Evidence suggests that baseline depression and anxiety may indicate how depression and anxiety symptoms change during and after attending WW. Measurement of depression and anxiety at the start of a behavioural weight management programme and subsequent monitoring may facilitate timely psychological support if a deterioration in mental health is identified. Further research in large and diverse participant samples is required to clarify the findings.

General self-efficacy in the Norwegian population: Differences and similarities between sociodemographic groups

Aims: General self-efficacy (GSE) refers to optimistic self-beliefs of being able to perform and control behaviors, and is linked with various physical and mental health outcomes. Measures of self-efficacy are commonly used in health research with clinical populations, but are less explored in relationship to sociodemographic characteristics in general populations. This study investigated GSE in relation to sociodemographic characteristics in the general population in Norway. Methods: As part of a larger national survey, the GSE scale was administered to a general population sample, and 1787 out of 4961 eligible participants (response rate 36%) completed the scale. Group comparisons were conducted using independent t-tests and one-way analyses of variance. Linear regression analysis was used to examine factors independently associated with GSE. Results: GSE was lower for older compared to younger participants (p < 0.001). It was higher for men compared to women (p < 0.001), higher for those with higher levels of education compared to those with lower levels (p < 0.001) and higher for those in work compared to their counterparts (p < 0.001). Controlling for all variables, male gender and employment were independently associated with higher GSE. Age moderated the associations between gender and employment on one hand, and GSE on the other. The association between being male and having higher GSE was more pronounced in younger age, as was the association between being employed and having higher GSE. Conclusions: Male gender and being employed were related to higher GSE among persons in the general population in Norway, and these associations were stronger among persons of younger age. The findings are considered fairly representative for the Norwegian population.
