Section III of DSM-5 includes an alternative model for personality disorders comprising five higher-order pathological personality traits, four of which resemble domains from the Big Five/Five-Factor Model of Personality (FFM). There has, however, been considerable debate regarding the association of FFM Openness-to-Experience/Intellect (OE/I) with DSM-5 Psychoticism and Schizotypal Personality Disorder (STPD). The authors identify several limitations in the literature, including inattention to (a) differences in the conceptualization of OE/I in the questionnaire and lexical traditions and (b) the symptom heterogeneity of STPD. They then address these limitations in two large patient samples. The results suggest that OE/I per se is weakly associated with Psychoticism and STPD symptoms. However, unique variance specific to the different conceptualizations of OE/I demonstrates much stronger associations, often in opposing directions. These results clarify the debate and the seemingly discrepant views that OE/I is unrelated to Psychoticism and contains variance relevant to Psychoticism.
The psychological benefits of physical exercise have been reported in numerous populations. While studies have found elevated stress and depressed mood during pregnancy and no adverse birth effects associated with low to moderate intensity exercise, few have examined exercise in relation to psychosocial outcomes during pregnancy. The present study examined leisure-time physical activity (LTPA) patterns during pregnancy and its association to psychological well-being. In each trimester of pregnancy 180 women self-reported on frequency, form and duration of LTPA through structured interviews. Beginning in the third month of pregnancy, data was collected monthly on depressed mood (Lubin depression adjective checklist), state-anxiety, pregnancy-specific stress (pregnancy experiences questionnaire) and Hassles Scale. Independent samples t-tests comparing exercisers and non-exercisers in each trimester showed exercisers reported significantly less depressed mood, daily hassles, state-anxiety and pregnancy-specific stress in the first and second trimester. Women who exercised in the third trimester reported less state-anxiety in that trimester compared to non-exercisers. The results indicate a consistent association between enhanced psychological well-being, as measured by a variety of psychosocial inventories, and LTPA participation particularly during the first and second trimesters of pregnancy. In healthy pregnant women, even low-intensity regular exercise may be a potentially effective low-cost method of enhancing psychological well-being.
Objective. To examine the relationship between disease-related variables, leisure-time physical activity (LTPA), and mental health status with fatigue severity in patients with spondylarthropathy (SpA). Methods. Sixty-six SpA patients completed questionnaires assessing disease activity (Bath Ankylosing Spondylitis Disease Activity Index [BASDAI]), functional ability (Bath Ankylosing Spondylitis Functional Index), and health-related quality of life (Short Form 36). LTPA patterns, demographics, and disease-related data were obtained by interview. A clinical examination determined tender point count. Fatigue was assessed with the BASDAI fatigue item. Results. The mean BASDAI fatigue score was 5.5 (SD ؍ 2.7) with 59% of the sample obtaining a score >5. Disease activity, functional disability, and worse mental health contributed to greater fatigue (R 2 ؍ 0.56). The relationship between exercise duration and fatigue intensity was moderated by mental health status. For patients with poorer mental health scores, exercise did not influence fatigue severity. However, for patients reporting better mental health status, engaging in more LTPA decreased fatigue severity. Conclusion. In addition to increased disease activity and functional disability, greater fatigue severity in SpA is associated with poorer mental health status. Integrating regular leisure physical activity into the comprehensive treatment of SpA may be useful for modulating fatigue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
