The Benefits and Barriers model of NSSI postulates that engagement in NSSI is positively reinforced by potent benefits, however there are a host of barriers to engagement, any one of which is salient enough to prevent engagement. It is possible that individual differences in sensation seeking, a trait that describes optimal level of positive reinforcement, may alter the balance between the benefits and barriers of engagement in NSSI. There are significant associations between engagement in NSSI and sensation seeking in college undergraduates, a population with disproportionately high rates of NSSI. However, it is unclear whether these traits play a similar role in adolescents. We expected that higher levels of sensation seeking would positively relate to any NSSI history, lifetime frequency of NSSI, and earlier age at onset of NSSI among a sample of 200 adolescents in a psychiatric hospital. Consistent with previous research, results indicated that females were more likely to engage in NSSI than males. Additionally, increased sensation seeking was associated with greater likelihood of ever engaging in NSSI and a greater number of different NSSI methods tried. Though we expected sensation seeking would be significantly related to lifetime NSSI frequency and earlier onset of NSSI, it was not. Findings suggest that individual differences may alter relations between the benefits and barriers of NSSI and that measuring sensation seeking in adolescents, especially females, and especially those experiencing psychological distress, may identify those at highest risk for engaging in NSSI and may allow for targeted intervention with these individuals.

Sensation seeking and emotion dysregulation have been identified as contributing factors for consequences associated with cannabis use, although findings have been mixed. The study seeks to clarify relations between sensation seeking, emotion dysregulation, and cannabis-related consequences. Cannabis users (N = 2,128) were assessed for facets of sensation seeking, emotion dysregulation, and cannabis-related consequences. Results revealed a positive association between risk seeking and cannabis-related consequences, as well as between emotion dysregulation and cannabis-related consequences. A negative association was observed between experience seeking and cannabis-related consequences. An interaction was found between emotion dysregulation and risk seeking. Risk seeking appears to be a risk factor for cannabis-related consequences at lower levels of emotion dysregulation. At high levels, the effect of emotion dysregulation superseded that of risk seeking. These findings have implications for the prioritization of clinical concerns in individuals seeking treatment for problematic cannabis use. [ABSTRACT FROM AUTHOR]

Research examining hallucinogen use has identified potential benefits, as well as potential harms, associated with use. The acute effects of hallucinogen use can be intense, disorienting, cognitively impairing, and may result in perceptual changes mimicking aspects of temporary psychosis. Hallucinogen use may also lead to the onset of more chronic issues, such as Hallucinogen Persisting Perception Disorder, which impairs daily functioning even when sober. However, research on factors that predict who will misuse hallucinogens is an understudied area. In particular, while sensation seeking, impulsivity, and emotion dysregulation have all been shown to be predictive of problematic substance misuse, there is almost no research on how these personality variables predict hallucinogen use. The present study assessed how these personality traits predicted hallucinogen use in a sample of college undergraduates (N = 10,251) and a sample of adolescents in an inpatient residential psychiatric hospital (N = 200). Results indicated that facets of sensation seeking, impulsivity, and emotion dysregulation positively predicted ever having used hallucinogens, earlier initiation of use, and lifetime use among college students. Findings also indicated that facets of sensation seeking, impulsivity, and emotion dysregulation positively predicted having ever used hallucinogens in the adolescent inpatient sample. Results highlight the need for more research on who is likely to misuse hallucinogens. If confirmed in future research, the findings presented herein indicate viable personality variables as predictors. This is especially important as there has been a recent explosion of research on the positive benefits of therapeutic hallucinogen use. [ABSTRACT FROM AUTHOR]
