The present investigation examined the factor structure, internal consistency, and construct validity of the 16-item Anxiety Sensitivity Index (ASI; Reiss Peterson, Gursky, & McNally 1986) in a young adult sample (n = 420) from the Netherlands. Confirmatory factor analysis was used to comparatively evaluate two-factor, three-factor, and four-factor models(More)
The present investigation evaluated the measurement model and construct validity of marijuana use motives as measured by the Marijuana Motives Measure (MMM; [Simons, J., Correia, C. J., Carey, K. B., and Borsari, B. E. (1998). Validating a five-factor marijuana motives measure: Relations with use, problems, and alcohol motives. Journal of Counseling(More)
The present investigation examined the incremental predictive validity of mindfulness-based processes, indexed by the Kentucky Inventory of Mindfulness Skills, in relation to posttraumatic stress symptom severity among individuals without any axis I psychopathology. Participants included 239 adults who endorsed exposure to traumatic life events. Results(More)
The present investigation examined the moderating role of anxiety sensitivity (AS) in regard to the relation between acute nicotine withdrawal and anxious and fearful responding to a 10% carbon dioxide-enriched air (CO2) procedure. Ninety daily smokers (35 women; M(age) = 28.87, SD = 12.12) were assigned randomly to one of two groups (12-hr nicotine(More)
The present investigation sought to examine the interactive effects of anxiety sensitivity [AS; Reiss, S., & McNally, R. J. (1985). Expectancy model of fear. In S. Reiss, & R. R. Bootzin (Eds.), Theoretical issues in behavior therapy (pp. 107-121). San Diego: Academic Press] and mindfulness [Brown, K. W., & Ryan, R. M. (2003). The benefit of being present:(More)
The present study evaluated differences among daily smokers with posttraumatic stress disorder (PTSD), panic disorder (PD), panic attacks (PA), and no axis I psychopathology (past 6 months) in terms of several cognitive-affective variables implicated in both the onset and maintenance of anxiety psychopathology and cigarette smoking. The sample consisted of(More)
Despite initial evidence linking distress tolerance to posttraumatic stress disorder (PTSD) symptom severity, there is a need for the investigation of interrelations among multiple measures of distress tolerance and PTSD symptom severity. Therefore, the present study investigated concurrent relations among multiple measures of distress tolerance, as well as(More)
The present investigation evaluated the relations between anxiety sensitivity and motivational bases of cigarette smoking, as well as barriers to quitting smoking, above and beyond concurrent substance use, negative affectivity, and emotional dysregulation among a community sample of 189 daily cigarette smokers (46% women; M(age)=24.97 years, SD=9.78).(More)
The purpose of the present investigation was to concurrently examine the latent dimensional and hierarchical structure of anxiety sensitivity (AS) and two key theoretically relevant and related affect (in)tolerance and sensitivity constructs: distress tolerance and discomfort intolerance. These constructs were measured using the Anxiety Sensitivity Index(More)
The present study examined the relations between posttraumatic stress disorder (PTSD) and cannabis use in a large representative survey of adults (N = 5,672) from the United States (Kessler et al., 2004). After adjusting for sociodemographic variables (i.e., age, marital status, ethnicity, education, income, and sex), alcohol use disorders, and nicotine(More)
