Perceived social support and longitudinal trajectories of depression and anxiety in World Trade Center responders.

PURPOSE: While severely distressing events are known to affect mental health adversely, some survivors develop only short-lived or no psychiatric symptoms in the aftermath of a disaster. In the WTC Health Program General Responder Cohort (WTCHP GRC) we examined whether social support was protective against the development of depression or anxiety symptoms after the 9/11 WTC attacks and explored in a subsample whether trait resilience moderated this relationship. METHODS: We analyzed data from 14,033 traditional and 13,478 non-traditional responders who attended at least three periodic health monitoring visits between 2002 and 2019. Linear mixed-effects models were used to examine depression (Patient Health Questionnaire-9; PHQ-9) and anxiety (Generalized Anxiety Disorder screener; GAD-7) scores. In a subsample of 812 participants, we also assessed if the association between social support and symptoms was moderated by an individual's trait resilience level (Connor-Davidson Resilience Scale, CD-RISC). RESULTS: For both traditional and non-traditional responders, perceived social support around 9/11 was associated with lower levels of depressive (ß = - 0.24, S.E. = 0.017, z = - 14.29, p < 0.001) and anxiety symptoms (ß = - 0.17, S. E. = 0.016, z = - 10.48, p < 0.001). Trait resilience scores were higher in responders with at least one source of social support during the aftermath of 9/11 compared to those without (mean 71.56, SD 21.58 vs mean 76.64, SD 17.06; ß = 5.08, S.E. = 0.36, p < 0.001). Trait resilience moderated the association between social support and depressive (p < 0.001) and anxiety trajectories (p < 0.001) for traditional responders. CONCLUSION: Our findings suggest that perceived social support around a severely distressing event may have long-term protective effects on symptoms of depression and anxiety.

Autistic traits and alcohol use in adolescents within the general population.

It has been suggested that autistic traits are associated with less frequent alcohol use in adolescence. Our study seeks to examine the relationship between autistic traits and alcohol use in a large adolescent population. Leveraging data from the IMAGEN cohort, including 2045 14-year-old adolescents that were followed-up to age 18, we selected items on social preference/skills and rigidity from different questionnaires. We used linear regression models to (1) test the effect of the sum scores on the prevalence of alcohol use (AUDIT-C) over time, (2) explore the relationship between autistic traits and alcohol use patterns, and (3) explore the specific effect of each autistic trait on alcohol use. Higher scores on the selected items were associated with trajectories of less alcohol use from the ages between 14 and 18 (b = - 0.030; CI 95% = - 0.042, - 0.017; p < 0.001). Among adolescents who used alcohol, those who reported more autistic traits were also drinking less per occasion than their peers and were less likely to engage in binge drinking. We found significant associations between alcohol use and social preference (p < 0.001), nervousness for new situations (p = 0.001), and detail orientation (p < 0.001). Autistic traits (social impairment, detail orientation, and anxiety) may buffer against alcohol use in adolescence.

Early predictors of mental health in mid-adulthood.

AIM: Substantial research has focused on the examination of factors that contribute to the development of psychiatric problems. However, much less is known about factors early in life that may protect from poor mental health outcomes in midlife. This study aimed to identify the extent to which a set of key perinatal demographic variables and adolescent academic performance were associated with good mental health in mid-adulthood. METHODS: In a sample of 525 individuals (aged 34-44, 55.4% male) born and raised in Jerusalem, Israel (STREAM study) we attempted to differentiate those who did and did not report psychiatric symptoms in mid-adulthood. Using χ2 and regression analysis, we explored birth factors (year of birth, sex, birth weight, and number of older siblings, data on parental immigration and socioeconomic status), academic achievement in eighth grade and contemporaneous measures of lifestyle factors, personality traits, and perceived resilience. RESULTS: Participants with good mental health were more often male (P = .005) and had better academic performance already at adolescence than participants who reported psychiatric symptoms in midlife (P < .001). They reported fewer physical complaints (P = .008), were less likely to smoke (P = .001) and considered themselves to be more "resilient" (P < .001). CONCLUSIONS: The results showed that better academic performance in adolescence may be associated with better stress-coping strategies, resulting in fewer psychiatric complaints, more perceived resilience, and less stress-related behaviours in mid-adulthood. Future studies confirming this hypothesis could inform public mental health interventions.
