Self-Acceptance and Purpose in Life Are Mechanisms Linking Adverse Childhood Experiences to Mortality Risk.

OBJECTIVE: Adverse childhood experiences (ACEs) are associated with an increased risk of premature mortality, but it is not clear why. Individuals with ACEs tend to have lower self-acceptance and purpose in life, which may be pathways between ACEs and risk of premature mortality. As such, we tested whether purpose and self-acceptance are mechanisms that link ACEs to mortality risk. METHODS: We used the Midlife in the United States Survey ( N = 6218; mean [standard deviation] = 46.89 [12.94] years) to test whether these factors were indirect pathways between ACEs and mortality hazards over 24 years of follow-up. We used a comprehensive ACE measure that included 20 possible childhood adversities including emotional and physical abuse, household instability, socioeconomic climate, and ill health. RESULTS: ACEs significantly increased mortality risk (hazard ratio = 1.028, 95% confidence interval = 1.008-1.047, p = .006). Self-acceptance and purpose accounted for an estimated 15% and 4% of the ACEs-mortality relation, respectively. These effects withstood a range of adjustments and sensitivity analyses. CONCLUSIONS: ACEs may affect mortality risk partially through lower self-acceptance and purpose during adulthood. Given that self-acceptance and purpose may change through intervention, these factors may be useful targets for individuals with ACEs that could lead to a longer life.

Personality trait associations with quality-of-life outcomes following bariatric surgery: a systematic review.

BACKGROUND: Obesity can be a significant challenge to health and quality of life (QoL). Bariatric surgery assists with weight loss and may help improve QoL. However, not all patients benefit from surgery. Personality traits may be related to QoL outcomes after bariatric surgery, but these associations are unclear. PURPOSE: This research reviews the published literature on the associations between personality and QoL among post-operative bariatric patients. METHOD: Four databases (CINAHL Complete, Medline with Full Text, APA PsycINFO, and Scopus) were searched from inception until March 2022. Forward searching was conducted using Google Scholar, and backward reference citation searches were also performed. RESULTS: Five studies met inclusion criteria yielding data from N = 441 post-bariatric patients including both pre/post and cross-sectional designs. Higher agreeableness was related to lower overall health-related QoL (HRQol) and gastric HRQol and positively associated with psychological HRQol. Higher emotional stability was positively related to overall HRQol. Higher impulsivity was negatively associated with mental HRQol and was unrelated to physical HRQol. Effects for the remaining traits were either mainly mixed or null. CONCLUSION: Personality traits may be associated with HRQol outcomes. However, it is difficult to reliably discern the role of personality traits for HRQol and QoL outcomes given the methodological issues and few published studies. More rigorous research is needed to address these issues and clarify possible associations.

Exploding head syndrome, chronotype, parasomnias and mental health in young adults.

Although inadequate sleep among young people is well documented in the literature, anomalous sleep experiences, such as the parasomnia termed exploding head syndrome (EHS), have received little empirical attention. The current study examined the association of sleep quality, symptoms of psychological distress and other unusual sleep experiences with EHS in a sample of young adults (n = 135, age M = 21.77, SD = 2.08). We also aimed to account for the possible effect of participant chronotype on sleep experiences. The lifetime prevalence of EHS among participants was 20.0%. Three-quarters (75.6%) of participants reported poor quality sleep according to the Pittsburgh Sleep Quality Index (PSQI). Univariate analysis showed that participants with a lifetime prevalence of EHS experienced more symptoms of anxiety and poorer sleep quality; age, gender and symptoms of depression were not significantly related to EHS. Parasomnias (OR [95% CI] = 1.62 [1.02-2.57], p = .040) and action-related sleep disorders (OR [95% CI] = 1.87 [1.09-3.20], p = .023) were associated with lifetime experience of EHS in a logistic regression analysis. Chronotype did not significantly impact mood, sleep quality or presence of EHS. Results suggest that EHS is more common in young people than previously considered and ought to be examined in conjunction with the presence of other unusual sleep disorders. This study provides valuable insight into young peoples' sleep experiences and key factors associated with EHS.
