Dysfunctional sleep-related cognition and anxiety mediate the relationship between multidimensional perfectionism and insomnia symptoms.

ABSTRACT: Perfectionism is one of several personality traits associated with insomnia. Whilst research has examined the relationships between perfectionism and insomnia, the mediating role of dysfunctional sleep-related cognition (i.e. sleep-related worry and dysfunctional beliefs about the biological attribution of and consequences of poor sleep) has yet to be examined. This study aimed to determine whether aspects of multidimensional perfectionism were related to increased reporting of insomnia symptoms. In addition, the potential mediating role of dysfunctional sleep-related cognition and anxiety symptoms was examined. Members of the general population (N?=?624) completed the Dysfunctional Beliefs and Attitudes About Sleep Scale, the Insomnia Severity Index, the Hospital Anxiety and Depression Scale, and the Multidimensional Perfectionism Scale. The results showed that perfectionism dimensions, anxiety symptoms, and dysfunctional sleep-related cognition were significantly associated with insomnia symptoms. Regression-based mediation analyses further showed that both dysfunctional sleep-related cognition and anxiety significantly mediated the associations between insomnia symptoms and three perfectionism dimensions (i.e. doubts about action, parental expectations, and parental criticism). The experience of perfectionistic tendencies, anxiety, and dysfunctional sleep-related cognition may initiate behavioural strategies (e.g. daytime napping) when faced with an acute sleep problem. However, these strategies may serve to transition insomnia from an acute to a chronic condition.

Project description:BACKGROUND:The association between perfectionism and depression in the medical profession can ultimately influence physicians' performance negatively. In medical students, especially maladaptive perfectionism is connected with distress and lower academic performance. The expression of perfectionism and symptoms of depression at the time of medical school application is not known. Therefore, we explored perfectionism and symptoms of depression in participants of multiple mini-interviews for medical school admission and investigated possible differences between applicants who were eventually admitted or rejected. METHODS:After the multiple mini-interviews admission procedure at Hamburg Medical School in August 2018, 146 applicants filled out a questionnaire including sociodemographic data and the following validated instruments: Multidimensional Perfectionism Scale by Hewitt and Flett (MPS-H), Multidimensional Perfectionism Scale by Frost (MPS-F), Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), and a 10-item version of the Big Five Inventory (BFI-10). The two groups of admitted and rejected applicants were compared and the correlation between symptoms of depression and perfectionism further explored. RESULTS:The admitted applicants were significantly more extrovert and had lower depression scores compared to the rejected applicants. In both groups, the composite scales of Adaptive Perfectionism (r = .21, p = .011) and Maladaptive Perfectionism (r = .43, p < .001) as well as their components correlated significantly with the PHQ-9 results. Maladaptive Perfectionism accounted for about 18% of variance in the PHQ-9 score. CONCLUSIONS:Rejected medical school applicants who participated in a multiple mini-interviews admission procedure showed higher levels of depression symptoms than admitted applicants. The degree of depressive symptoms can be partly explained by Maladaptive Perfectionism scores. Since coping in medical school and in postgraduate medical education require robust mental health, perfectionism questionnaires could be an additional tool in medical school selection processes.

Project description:STUDY OBJECTIVES:The goal of this study was to examine daily associations between sleep and cognition in older adults suffering from insomnia, with or without a history of chronic pain. METHODS:Sixty older adults with insomnia and a history of chronic pain (HxCP; n = 33, mean age = 69.5 years, standard deviation = 7.8) or no history of chronic pain (NCP; n = 27, mean age = 69.7 years, standard deviation = 7.9) completed 14 days of diaries and actigraphy, measuring sleep onset latency (SOL), wake after sleep onset (WASO), sleep efficiency (SE), and sleep quality. Participants completed daily cognitive measures of processing speed (ie, symbol digit modalities test, SDMT), reasoning (ie, letter series), and verbal memory (ie, word list delayed recall). For HxCP and NCP, associations between sleep parameters, daily pain, depressive symptoms (ie, Beck Depression Inventory, Second Edition scores), and daily cognition, controlling for age, and global cognition were examined through multilevel modeling. RESULTS:For HxCP, greater self-reported WASO was associated with worse next-day SDMT performance, whereas greater actigraphic WASO was associated with better next-day SDMT performance. Greater depression was associated with worse daily letter series performance. Greater self-reported WASO and SE were associated with better next-day delayed recall. For NCP, greater self-reported WASO and depression were associated with better daily SDMT performance, whereas worse daily pain was associated with worse SDMT and delayed recall performance. CONCLUSIONS:In older adults with HxCP, improving sleep may benefit lower level cognition, whereas reducing depression may affect higher level cognition. Discrepancies in sleep parameters promote assessment of objective and subjective sleep outcomes when investigating effects of insomnia on cognition.
