27, p = .004; small-medium effect size) and negatively related to perceived difficulty of coping (r = �C.23, p = .02; small effect size). In support of predictive validity, selleckchem Tubacin the STCQ scale score was significantly related to length of abstinence at follow-up (r = .46, p = .002; large effect size). We used the product-of-coefficients procedures outlined by MacKinnon, Lockwood, Hoffman, West, and Sheets (2002) to test mediation. Significance of the individual mediated effect was assessed using MacKinnon’s z�� distribution. In the full model with past-month smoking and temptation coping as predictors, the effect of past-month smoking remained significant, with greater smoking predicting briefer abstinence (sr2 = .08, p = .036).

However, partial mediation was supported in that the indirect effect of past-month smoking through temptation coping was significant (z�� = �C1.69, p < .01), accounting for 30% of the total effect of past-month smoking on abstinence duration. Finally, as hypothesized, temptation coping did not predict engagement in a cessation attempt, t(95) = �C1.41, p = .16. Discussion The present study examined the STCQ, a brief measure of adolescent coping with temptations to smoke in the face of social pressure. EFA yielded a single factor consisting of six temptation-coping strategies. Analyses provided support for the concurrent, predictive, and construct validity of the STCQ. In particular, the coping scale score significantly predicted duration of abstinence for adolescents who engaged in self-change smoking cessation efforts.

Results provided support for the social cognition model of adolescent addictive behavior self-change. Content for four of the STCQ coping items reflected thinking about the consequences of a return to smoking, cognitive strategies that may reinforce motivation for abstinence by focusing on negative consequences of smoking and the desire to not smoke. The remaining two items, doing something instead of smoking and concentrating on what to do next, may manage temptation by shifting attention away from urges to smoke. Scale content was similar to strategies reported in a previous study of adolescent coping with temptation to smoke (Jannone & O��Connell, 2007). Coping scale scores significantly predicted abstinence duration among adolescents who engaged in smoking cessation efforts.

Noteworthy was the magnitude of association between coping scores and abstinence duration, corresponding with a large effect size (Cohen, 1988). Notwithstanding the small sample, the strength of this correlation was surprising GSK-3 given the hypothetical nature of coping assessment and the relatively long (6 month) follow-up interval. These scores may represent a greater probability of engaging in any coping when confronted with temptation. These findings suggest that assessment of coping with temptations in response to a hypothetical situation has value for predicting subsequent cessation efforts.
