Posttraumatic stress disorder (PTSD) frequently co-occurs with addictive behaviors. Recently, the addictive behavior of excessive smartphone use is being widely researched. Impulsivity commonly relates to PTSD severity and problematic smartphone use. However, unexamined is the mediating role of impulsivity facets (lack of premeditation, negative urgency, sensation seeking, and lack of persevera...

Adolescents show a heightened susceptibility to peer influence compared to adults. Individual differences in this susceptibility exist, yet there has been little effort to link these with broader personality processes. Reward sensitivity and impulsive behaviour are also heightened in adolescence and could affect the tendency to be influenced by peers. This study examined associations between se...

Theories of nonsuicidal self-injury (NSSI) and impulsivity suggest that individuals with high levels of negative urgency (e.g., those with a propensity to act rashly while experiencing negative affect) should experience the urge to engage in NSSI during negative affect states. However, previous research has not directly tested these predictions. This study used a daily diary methodology in a sa...

This research aims to study the existing relationships among the factors of state anxiety, depression, impulsivity, and alcohol consumption regarding problematic mobile phone use, as assessed by the Mobile Phone Problem Use Scale. The study was conducted among 1,126 participants recruited among the general Spanish population, aged 16-65 years, by assessing the predictive value of these variable...

HIV is most prevalent among men who have sex with men (MSM), and although most MSM use condoms consistently during casual sex, some take risks. To better understand the psychology of those risky decisions, we examined neural correlates of playing a virtual sexual 'hook up' game in an functional magnetic resonance imaging scanner in MSM who had, in the past 90 days, been sexually risky (N = 76) ...

Suicidality and violence are serious public health problems. A rich literature supports the relationship between suicidality and violence, including common associations with trait anger. However, less is known about how trait anger may facilitate these behaviors. Two potential mechanisms in this relationship are emotion dysregulation and impulsivity, both of which are linked to increased anger,...

How does impulsivity relate to risky sexual behavior? Whereas some research has attempted to answer this question in terms of global impulsivity, past research has demonstrated the need to conceptualize impulsivity as a multifaceted trait (Whiteside & Lynam, 2001). Research has been mixed as to which facets of impulsivity predict risky sexual behavior. The major aim of this project was to furth...

OBJECTIVE This study assesses the influence of the auditory characteristics of alerts on perceived urgency and annoyance and whether these perceptions depend on the context in which the alert is received. BACKGROUND Alert parameters systematically affect perceived urgency, and mapping the urgency of a situation to the perceived urgency of an alert is a useful design consideration. Annoyance a...
