RESUMEN
To determine the efficacy of the TTM to predict exercise behavior in a sample of Iranian college students. This was a cross-sectional study. Participants were 418 first year students of Guilan University of Medical Sciences who completed Iranian versions of the TTM and exercise behavior questionnaires. Data were analyzed using bivariate correlation and path analysis. In the final model, path coefficient for the processes of change [behavioral strategy], self-efficacy in exercise and pros were 0.54, 0.20 and -0.11 respectively. The model accounted for 38% of the variance for predicting current exercise behavior. The study findings support the application of TTM in exercise behavior changes among Iranian students
RESUMEN
To assess the effect of a theory based intervention among adolescents in a study on intention of substance abuse avoidance among young adolescents, in Tehran, Iran. Fifty-five high school male students aged between 15 and 19 randomly were allocated into tow study groups: intervention and control group. The intervention group received an educational program based on the developed Reasoned Action Theory in order to examin its effect on beliefs, while the control group didnt receive any programs. The intervention group showed significant improvements in attitude, self efficacy [subjective norms exception] and substance abuse avoidance intention [P<0.001]. A decrease in substance use and cigarette-smoking was reported by students in intervention group. Results of this study indicated that a theory based intervention was effective for substance abuse among adolescents
RESUMEN
To assess the effect of processes of change on resistance skills against substance abuse among petrochemical workers in Assaluyeh Plant in Iran. This was an experimental study [randomized intervention trial]. In all 181 workers of petrochemical company in Assaluyeh were enterd into the study [90 participants in intervention group and 91 participants in control group]. Data were collected by a questionnaire that was designed and validated by the researchers based on the Trans Theoretical Model [TTM]. Both groups were interviewed before the intervention, based on which the educational needs were identified. One of the diagnostic surveys showed lack of resistance skills against substance abuse that required further education. To meet this requirement a TTM based education for intervention was applied. The study showed significant improvement in most of the resistance skills among the intervention group, while both groups showed no significant differences in use of processes of change before the intervention [except for construct self revolution, that was higher in control group]. The results after the intervention showed that intervention group had used all elements of processes of change [except dramatic relict]. This study showed that processes of change in the TTM would lead to improved knowledge, attitude, self efficacy and self control. It also confirmed that the training materials based on the trans theoretical model can develop resistance skills against substance abuse that will ultimately result in a better health among the workers and could create a drug free workplace [safe workplace]. Based on these findings the investigators recommend that all studies on health related change behavior should continually use the behavioral theories and models
