Patterns of Use, Acute Subjective Experiences, and Motivations for Using Synthetic Cathinones ("Bath Salts") in Recreational Users.

Given the variety and potential toxicity of synthetic cathinones, clinicians and educators would benefit from information about patterns of and motivations for use, frequency of psychosocial consequences, and experience of acute subjective effects. We administered a comprehensive, web-based survey to 104 recreational users of synthetic cathinones. Sixty percent of respondents consumed synthetic cathinones once or more per month, usually snorting or swallowing these drugs, typically at home, usually with others, customarily during the evening and nighttime hours, and often in combination with another drug such as alcohol or marijuana. Acute subjective effects attributed to synthetic cathinones were similar to those of other psychostimulants, including increased energy, rapid heartbeat, racing thoughts, difficulty sleeping, euphoria, decreased appetite, open-mindedness, and increased sex drive. Reported reasons for using synthetic cathinones included its stimulating effects, curiosity, substitution for another drug, and being at a party/music event. Respondents had experienced an average of six negative consequences of using synthetic cathinones during the previous year (e.g., tolerance, neglecting responsibilities, personality change). In combination with previously published investigations, these findings increase our understanding of the reported rationales and outcomes of recreational use of synthetic cathinones.

Development and evaluation of the Marijuana Reduction Strategies Self-Efficacy Scale.

To evaluate several psychometric properties of a questionnaire designed to assess college students' self-efficacy to employ 21 cognitive-behavioral strategies intended to reduce the amount and/or frequency with which they consume marijuana, we recruited 273 marijuana-using students to rate their confidence that they could employ each of the strategies. Examination of frequency counts for each item, principal components analysis, internal consistency reliability, and mean interitem correlation supported retaining all 21 items in a single scale. In support of criterion validity, marijuana use-reduction self-efficacy scores were significantly positively correlated with cross-situational confidence to abstain from marijuana, and significantly negatively correlated with quantity and frequency of marijuana use and marijuana-related problems. In addition, compared with respondents whose use of marijuana either increased or remained stable, self-efficacy was significantly higher among those who had decreased their use of marijuana over the past year. This relatively short and easily administered questionnaire could be used to identify college students who have low self-efficacy to employ specific marijuana reduction strategies and as an outcome measure to evaluate educational and skill-training interventions.

Binds and bounds of communion: effects of interpersonal values on assumed similarity of self and others.

Assumed similarity refers to ascribing similar attributes to the self and others. Because self-other similarity facilitates communion, people who value communion should be prone to assume self-other similarity; but because self-other similarity also evokes obligation, they may be prone to assume similarity only with others with whom they are or would feel comfortable being interconnected. We tested these hypotheses in 5 studies (total N = 1,709). In Study 1, students indicated their political preferences and estimated other students' preferences. In Studies 2-5, students described their personality and the personalities of the following targets: actual or imagined romantic partners in Study 2; ingroup members (students from the respondents' university) and outgroup members (students from a foreign university) in Studies 3-4; and specific liked and disliked others in Study 5. As hypothesized, people with stronger communal values were more likely to assume self-other similarity with liked others, romantic partners, and ingroup members, but not with disliked others and outgroup members. These effects replicated across different cultures (India, Korea, and the United States) and remained significant when controlling for self-esteem, national identification, and attribute desirability. Although people who valued communion tended to depict themselves and liked and ingroup others in relatively normative (typical) ways, which partially explained assumptions of similarity and indicated that those assumptions were to some extent accurate, communal values continued to predict distinctive self-other similarity or "false consensus" even after controlling for the normative prevalence of attributes.
