Predictors of health behavior from an behavior-analytic orientation.

The frequencies of American college students' positive self-talk, emotional reactions, and other positive thoughts for engaging in five health behaviors were assessed and found to be highly correlated; they then were combined into a composite measure. A similar composite resulted for negative self-talk, emotional reactions, and other negative thoughts for engaging in unhealthy alternative behaviors. Effortfulness and pleasantness of the health behaviors were also assessed. One or (in some cases) both composites, effortfulness, and pleasantness were substantially related to vigorous exercise, use of seat belts, and avoidance of alcoholic beverages. Mild exercise and avoidance of junk food were less well predicted.
