Mastery experience	● Interventions were tailored to the participant’s ability and gradually increased over time ● Periodic individual updates on the participant’s overall progress (i.e., progress charts) ● Use of logs reflecting achievements in diet and exercise
Vicarious experience	● Participants were assigned to a group where they attended diet counseling or exercise sessions with other older, overweight and obese individuals with knee osteoarthritis
Verbal persuasion	● Built-in pattern of frequent contact that demonstrated personal interest in the participant ● Interventions were supervised by trained interventionists who encouraged participants ● Interventionists helped participants create measurable and attainable goals
Physiological cues/psychological states	● Interventionists helped participants interpret physiological responses to starting an exercise program (i.e., pain, soreness) ● In the exercise intervention groups participants were shown how to monitor heart rate and complete activity logs ● In the diet intervention groups participants received specific counseling in adapting to a lower calorie diet ● Interventionists talked with patients about their stress and anxiety for making lifestyle changes
