Objectives: Anxiety sensitivity (AS) is associated with cannabis use. People high in AS may use cannabis to cope with elevated anxiety. This association is consistently supported in the literature. However, we have much to learn about the mechanisms of the AS pathway to cannabis use. We aimed to examine negative urgency--the tendency to act impulsively when distressed--as a mediator of the association of AS with cannabis problems and cannabis dependence symptoms. We hypothesized that negative urgency would uniquely mediate the association of AS with cannabis outcomes after controlling for other facets of impulsivity. Participants and Methods: Postsecondary students (N = 91; Fall 2012) completed online self-reports. To participate, students needed to be =18 years old, enrolled in postsecondary studies, and needed to report current cannabis use. Results: Negative urgency uniquely mediated associations between AS and cannabis problems and dependence symptoms. Conclusions: Our findings suggest a mechanistic role of negative urgency in the AS pathway to cannabis misuse.

We examined the utility of the validity scales on the recently released Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2 RF; Ben-Porath & Tellegen, 2008) to detect overreported psychopathology. This set of validity scales includes a newly developed scale and revised versions of the original MMPI-2 validity scales. We used an analogue, experimental simulation in which MMPI-2 RF responses (derived from archived MMPI-2 protocols) of undergraduate students instructed to overreport psychopathology (in either a coached or noncoached condition) were compared with those of psychiatric inpatients who completed the MMPI-2 under standardized instructions. The MMPI-2 RF validity scale Infrequent Psychopathology Responses best differentiated the simulation groups from the sample of patients, regardless of experimental condition. No other validity scale added consistent incremental predictive utility to Infrequent Psychopathology Responses in distinguishing the simulation groups from the sample of patients. Classification accuracy statistics confirmed the recommended cut scores in the MMPI-2 RF manual (Ben-Porath & Tellegen, 2008). (Contains 7 footnotes, 4 tables, and 1 figure.)
