The effects of alcohol and marijuana co-use patterns on intimate partner aggression perpetration.

Alcohol and marijuana are two of the most widely used substances in the U.S, with rates of alcohol and marijuana co-use increasing in recent years. Despite this increase, little is known about the effects of alcohol and marijuana co-use patterns (e.

Dyadic effects of minority stress and problematic alcohol use on sexual intimate partner violence in same sex couples.

Little is known about the factors that facilitate the perpetration of sexual violence within the context of same-sex romantic relationships (sexual intimate partner violence perpetration [S-IPV]). The present study sought to identify the effects of external and internal minority stress and problematic drinking on perpetration of S-IPV within a dyadic framework. A community-based sample of 137 sexual and gender minority (SGM) couples (N = 274; 59 male assigned at birth and 78 female assigned at birth couples) completed self-report surveys about minority stressors, alcohol use, and S-IPV perpetration.

Alcohol, Trait Anger, and Psychological Flexibility: A Laboratory Investigation of Intimate Partner Violence Perpetration.

The I Model is a meta-theoretical framework that posits intimate partner violence (IPV) perpetration is the product of three interactive factors: instigators, impellors, and inhibitors. The present study examined the effects of trait anger (an impellor), psychological flexibility (a disimpellor), and alcohol intoxication (a disinhibitor) on IPV perpetration. Participants were 249 heavy drinkers (41% female) who had perpetrated IPV toward their current partner in the past year.

Sexual Violence Perpetration Within Intimate Relationships: An I Model Analysis of the Effects of Sexual Violence Victimization and Psychological Flexibility.

The I Model posits that intimate partner violence (IPV) is determined by the relative strength of instigatory, impellance, and inhibitory factors. Although much research has examined nonsexual IPV, few studies have used the I Model to examine sexual IPV. This study investigated the effects of sexual IPV victimization (an impellor) and psychological flexibility (an inhibitor) on sexual IPV perpetration within a dyadic framework.

Isolated Sleep Paralysis: Fear, Prevention, and Disruption.

Objectives: Relatively little is known about isolated sleep paralysis (ISP), and no empirically supported treatments are available. This study aims to determine: the clinical impact of ISP, the techniques used to prevent or disrupt ISP, and the effectiveness of these techniques.

Method: 156 undergraduates were assessed with lifetime ISP using a clinical interview.
