Evidence indicates acute sleep deprivation affects negative mood states. The present study experimentally tested the effects of acute sleep deprivation on self-reported symptoms of state anxiety and depression as well as general distress among 88 physically and psychologically healthy adults. As hypothesized, the effects of acute sleep deprivation increased(More)
Millions of individuals with posttraumatic stress disorder (PTSD) are parents. A burgeoning literature suggests that offspring of parents with this condition may be at increased risk for psychological problems. The current paper provides an integrative and comprehensive review of the diverse research literature examining the sequelae of parental(More)
Research indicates changes in HPA-axis activity across puberty. The current study extends existing work by evaluating pubertal status and cortisol level in a novel social environment (research laboratory) while controlling for several important biological, behavioral, and psychological variables. Participants were 30 girls (ages 9-16 years) from the United(More)
Adolescent alcohol use is a critical public health concern; accordingly, a considerable body of work exists identifying developmentally salient risk and protective factors. One area receiving increasing attention among adults is the linkage between specific constellations of anxiety psychopathology and alcohol use problems. Relatively less is known about(More)
This study examined the associations among perceived control over anxiety-related events, worry, and both symptoms and diagnoses of generalized anxiety disorder (GAD). The sample was comprised of 140 adolescents (60 girls) between the ages of 10 and 17 years (M ( age ) = 14.6 years; SD = 2.25) recruited from the general community. Findings were consistent(More)
OBJECTIVES The role of social support in predicting health among grandparents raising grandchildren was explored among 86 grandparent caregivers assessed twice over a 1-year timeframe. METHOD Relationships between social support and health were ascertained via cross-lagged analyses. Regression analyses explored the mitigating role of social support in(More)
Previous studies have produced mixed results when examining whether experiencing an adverse event can lead to changes in Neuroticism. We sought to examine this effect when (a) the event was relatively recent, (b) the event occurred during a relatively early development stage (i.e., emerging adulthood), and (c) the event was severely adverse. A sample of(More)
The interaction between early maturation and problematic peer relations in relation to social anxiety symptoms was examined among 167 adolescents aged 10-17 years. Results indicated that early-maturing youth with problematic peer relations evidenced elevated social anxiety symptoms. Findings are discussed in terms of theoretical implications for adolescent(More)
Social anxiety evidences significant comorbidity with alcohol use disorders and alcohol-related problems. In an effort to better understand this co-occurrence, researchers are beginning to evaluate specific drinking-related factors, including alcohol use motives, among socially anxious individuals. Drawing on Cooper's (1994) 4-factor model of drinking(More)
Posttraumatic stress symptoms and self-reported sleep problems reliably covary. The current study investigated how posttraumatic stress symptom clusters (i.e., hyperarousal, avoidance, and reexperiencing) relate to trouble initiating and maintaining sleep and nightmares. Participants included traumatic event-exposed respondents from the NCS-R. Results(More)
