title: Action and coping planning with regard to dental brushing among Iranian adolescents.
abstract: The aims of this study were two-fold: (i) to examine the validity of the proposed three-factor structure (intention, action-, and coping planning) in an Iranian sample of adolescents, and (ii) to assess the predictive ability of the Theory of Planned Behavior (TPB) measures of action planning and coping planning for dental brushing. Eight hundred adolescents were randomly selected to participate in the study. 90% (721) of adolescents agreed to participate. Perceived behavioral control, action and coping planning scales and a self-report questionnaire related to dental brushing behavior were completed by the adolescents at baseline. One month later (time-point 2), the adolescents were asked to reassess their frequency of dental brushing over the four week period. Data were analyzed by a confirmatory factor analysis (CFA) on an original three-factor structure (intention, action plan, and coping plan). A hierarchical linear regression analysis was also performed. The CFA for the original three-factor structure showed a good fit index (χ(2) = 637.60, degrees of freedom df = 116), goodness-of-fit index (GFI) = 91, and root mean square error of approximation (RMSEA) = 0.079. Adjusting for demographic variables, action- and coping planning together accounted for 7.9% of the variance associated with dental brushing behavior at one month. In conclusion, results suggest that action planning and coping planning are associated with higher frequency in dental brushing among Iranian adolescents.
