Importance: Exposure to adverse childhood experiences (ACEs) has consistently been associated with multiple negative mental health outcomes extending into adulthood. However, given that ACEs and psychiatric disorders cluster within families, it remains to be comprehensively assessed to what extent familial confounding contributes to associations between ACEs and clinically confirmed adult psychiatric disorders.

Objective: To investigate whether associations between ACEs and adult mental health outcomes remain after adjusting for familial (genetic and environmental) confounding.

Emerging data suggest that certain adverse childhood experiences (ACEs) are associated with perinatal depression (PND). However, few studies have comprehensively assessed the cumulative number and types of ACEs and their association to PND. We conducted a cross-sectional analysis among 16,831 female participants from the Stress-And-Gene-Analysis (SAGA) cohort in Iceland, 2018.

Article Synopsis
  • Childhood abuse and other adverse experiences (ACEs) are linked to premenstrual disorders (PMDs), specifically premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD), with a stronger correlation seen among those with multiple ACEs.
  • A study involving nearly 12,000 menstruating women showed that for every additional ACE experienced, the risk of PMDs increased by 12%, with women having four or more ACEs facing over double the risk compared to those with none.
  • The study found that all types of ACEs were associated with PMDs, but the strongest connections occurred in women lacking PTSD, anxiety, or depression, and those with lower social

Background: Adverse childhood experiences (ACEs) have consistently been associated with elevated risk of multiple adverse health outcomes, yet their contribution to coping ability and psychiatric resilience in adulthood is unclear.

Methods: Cross-sectional data were derived from the ongoing Stress-And-Gene-Analysis cohort, representing 30% of the Icelandic nationwide female population, 18-69 years. Participants in the current study were 26,198 women with data on 13 ACEs measured with the ACE-International Questionnaire.

Objective: Neuroticism is associated with poor health outcomes, but its contribution to the accumulation of health deficits in old age, that is, the frailty index, is largely unknown. We aimed to explore associations between neuroticism and frailty cross-sectionally and longitudinally, and to investigate the contribution of shared genetic influences.

Methods: Data were derived from the UK Biobank (UKB; n = 274,951), the Australian Over 50's Study (AO50; n = 2849), and the Swedish Twin Registry (Screening Across the Lifespan of Twins Study [SALT], n = 18,960; The Swedish Adoption/Twin Study of Aging [SATSA], n = 1365).

This article presents a new method for reducing socially desirable responding in Internet self-reports of desirable and undesirable behavior. The method is based on moving the request for honest responding, often included in the introduction to surveys, to the questioning phase of the survey. Over a quarter of Internet survey participants do not read survey instructions, and therefore, instead of asking respondents to answer honestly, they were asked whether they responded honestly.

Previous research shows that dyslexic readers are impaired in their recognition of faces and other complex objects, and show hypoactivation in ventral visual stream regions that support word and object recognition. Responses of these brain regions are shaped by visual statistical learning. If such learning is compromised, people should be less sensitive to statistically likely feature combinations in words and other objects, and impaired visual word and object recognition should be expected.
