Primarily American adults (n = 269) participated 6-month consisting motivational enhancement, support, pedometer diary self-monitoring, 5 education sessions. Outcome measures included pedometer-determined steps per day, fitness, intake, measures. Generalized linear mixed models were used test for behavioral outcomes, identify predictors changes, determine if predicted diet. RESULTS Postintervention apparent 10 24 (P < .05). Processes change components, including helping relationships, reinforcement management, consciousness raising, significant fitness CONCLUSION article the first address how several theoretical frameworks influence multicomponent, adults.
