Objectives: Posttraumatic stress disorder (PTSD) has been linked to risky sexual behavior (RSB). However, little is known regarding the role of impulsivity in this relation among college students. Participants: The present study examined the moderating role of impulsivity dispositions on the relation between PTSD symptoms and past-year RSB in a…

Objective: To examine the Acquired Preparedness Model using a behavioral impulsivity facet and positive marijuana expectancies to examine direct and indirect effects on marijuana use and related problems. Participants: 250 college students (61.7% female, 54% white) recruited from a southeastern university. Methods: Participants completed an online…

High-risk sexual behaviors (HRSBs; e.g., having sex without protection against pregnancy or sexually transmitted infections) are a public health problem. HRSBs disproportionally impact college students and are associated with numerous negative outcomes, such as unwanted pregnancies. Alcohol use has been strongly linked to HRSBs in college…

The present study investigated prenatal and early postnatal risk factors associated with developmental patterns of disruptive behaviors (DBs; e.g., hyperactivity-impulsivity, noncompliance, physical aggression) from ages 1.5 to 5 years in a population birth cohort (N = 2,057; 50.7% boys). Six high-trajectory classes obtained by latent growth…

Objective: Extreme sport participation and injury rates have increased in recent decades. This study aimed to investigate sub-dimensions of impulsivity and sensation seeking that contribute to participation and injury risk in extreme sports. Participants: Data included cross-sectional survey responses from 7,109 college students (Mage=19.68, SD =…

This study used a cross-lagged panel analysis to explore the effect of impulsivity and academic achievement on the development of suicidal ideation in adolescents using three-time assessments with an interval of 6 months. A total of 211 adolescents (104 boys, 107 girls with a mean age of 13.62 ± 0.68 years in the third assessment) completed the…

Objective: College students use electronic nicotine delivery systems (ENDS) more often than any other US demographic group. In a novel application of the acquired preparedness model, we examined how proximal (e.g., cognitions) and distal (e.g., dispositional) influences accounted for ENDS use and dependence. Participants: Undergraduates (N = 1075;…

This study examined whether age differences in risky decision making are dependent on known probability and value of outcomes (i.e., the expected value [EV]), the valence of anticipated outcomes (gains or losses), and individual differences in working memory and impulsivity. We used a task that varied risk independently from EV so that taking…

Objective: Problem-drinking among university students is common and poses serious health-related risks. Therefore, identifying and addressing associated factors is important. Participants and methods: A large cross-sectional online-survey with 12,914 university students from Berlin was conducted from November 2016 to August 2017. Relative-risk-…

Self-harm is purportedly common in autistic individuals, but under-researched, particularly in younger samples and those "without" intellectual disability. This study aimed to describe prevalence, profile and correlates of self-harm in autistic individuals without impairments in adaptive functioning. Parents of autistic participants (n =…

Sexual arousal is associated with increases in a variety of impulsive choices, such as engaging in unprotected sex, having sex with strangers, and more frequent sexual activity. Little is known about sexual arousal's association with impulsive choice for domain-specific outcomes using a laboratory measure of impulsive choice. This study…

The purpose of this study was to determine whether bullying perpetration in early adolescence is capable of predicting delinquency 1 year later. Nine control variables were included in a regression analysis of the bullying-delinquency relationship in 1,001 schoolchildren (X-bar age = 12.97 years). The nine control variables (age, sex, race, social…

Objectives: Researchers examined associations between specific forms of emotion dysregulation and numerous behavioral manifestations of impulsivity (i.e., problematic alcohol use, drug use, risky sexual activity, binge eating, non-suicidal self-injury). Participants: Participants were 238 undergraduate students (69% female). Method: Emotion…

Background: Problem behaviours are common among people with intellectual disabilities (ID), but psychometrically evaluated instruments for assessing such behaviours are scarce. The present study evaluated the psychometric properties of the Neuropsychiatric Inventory--Intellectual Disability (NPI-ID). Method: We assessed 108 residents with…

Suicide has become the second leading cause of death for individuals between 15 and 29 years old and increasingly more common within college students (WHO, 2016). The purpose of this study was to examine the associations among alexithymia, impulsivity, and locus of control as predictors of suicide risk in college students. Participants were…
