A sample of community women was surveyed to determine exercise habits, weight control methods, and perceived barriers to sustaining and initiating exercise and weight management programs. Lack of time was reported to be the most significant factor limiting exercise, while lack of willpower and time constraints were the most frequently reported obstacles to weight management. Suggestions to aid adherence to exercise and weight control programs among women are outlined.

This study examined the construct validity of 1 measure of Type A behavior, the Matthews Youth Test for Health (MYTH), with preschool-age children. Convergent and discriminant validity evidence was obtained based on teacher ratings, intelligence test scores, and reaction time in a visual discrimination task. As predicted, Type A behavior was related to ratings of aggression and impatience, but not to intelligence. An experimental analysis was conducted of the conjoint effect of 2 situational variables, time constraint and incentive, on reaction time. Children classified as Type A or Type B on the basis of the MYTH participated in a visual discrimination task either with or without the presence of a time constraint and an incentive. As predicted, the reaction times of Type B children who worked without a time limit and an incentive were significantly longer than both groups of Type A children and the Type B children who worked with a time limit and an incentive. In summary, support was obtained for the construct validity of the MYTH when used with preschool-age children.
