Abstract
This study was designed to examine components of both the social influence process in counseling and the conflict model of decision making. A group weight loss program was used as the setting to investigate the effects of client perceived need (high or low) and the balance sheet procedure (relevant or irrelevant) on subject commitment to weight loss. The outcome variables in this study were the number of class sessions attended, the number of homework assignments completed, and the proportion of weight change. Need was measured using a 7-point scale, asking subjects to rate their level of need for attending a weight loss program.
A total of 63 individuals attending "Be Trim!", a weight loss program offered by two hospital wellness programs, agreed to participate in this research project. From their responses to the need assessment scale, 30 persons were categorized as high need and 33 persons were categorized as low need. Random placement in the relevant or irrelevant balance sheet condition resulted in four groups: high need/relevant balance sheet (n = 15), low need/relevant balance sheet (n = 17), high need/irrelevant balance sheet (n = 15), and low need/irrelevant balance sheet (n = 16).
Using a two by two analysis of variance, no significant main effects or interaction effects were found for perceived need and the balance sheet on commitment to weight loss. Study results did not support the need component of the social power formula or the balance sheet procedures as a means of commitment enchancement. Limitations of the study and implications are addressed.
