Couples appear to frequently experience relationship problems, yet estimates of the prevalence and prediction of three distinct help-seeking steps, (1) recognition of serious relationship dissatisfaction, (2) considering help, and (3) receiving relationship help, are unknown for representative population samples. This is unfortunate as such knowledge may inform policy makers in the development of strategies to motivate couples to seek help. The prevalence of these steps along with reasons for not acquiring help was studied in a representative population sample of 1014 Dutch heterosexual couples.

  • This study explores how cognitive factors like pre-sleep arousal and sleep-related worry affect insomnia severity in college students over time.
  • Using data from 353 students at the start and 79 students a year later, the research highlights that pre-sleep arousal and sleep-related worry significantly contribute to current insomnia issues.
  • Importantly, sleep-related safety was identified as a key predictor for the persistence of insomnia over the year, suggesting it’s a crucial but often overlooked factor in insomnia development.

This study examined whether reductions in the severity of personality disorders (PD) mainly reflect changes in personality traits or rather an alleviation of a demoralized state involving nonspecific unpleasant affect. We used 4 years of longitudinal data from the Collaborative Longitudinal Personality Disorders Study, in which patients ( = 419) completed the Neuroticism-Extraversion-Openness Personality Inventory-Revised (NEO-PI-R) three times over 4 years (at baseline and at 6-month and 4-year follow-up assessments). We compared the NEO Demoralization scale with NEO-PI-R domain scales adjusted for demoralization-related items to determine whether changes in demoralization are more pronounced than changes in adjusted personality traits.
