Relationships among full constructs of the transtheoretical model using a sample of 121 adults with mild intellectual disabilities in Taiwan were examined. Self-reports of stages of change and transtheoretical model psychosocial measures were gathered through interviews. Although MANCOVA revealed that behavioral processes of change, cognitive processes of change, selfefficacy, and perceived pros increased across stages, we did not find a clear linear pattern of association. Direct discriminant function analysis indicated that the most important predictors of stages of change were behavioral processes, cognitive processes, and self-efficacy. The overall stage of change classification accuracy using transtheoretical model psychosocial constructs was 56.2%. Psychosocial measures specifically developed for this population should be further explored.
