Data from a mailed survey to primary care physicians (N = 122) were used to construct and evaluate psychosocial scales related to performance of smoking cessation counseling. Scales measuring counseling barriers, self-efficacy, and motivation demonstrated considerable promise with excellent or reasonable internal consistency. The correlation for each scale with performance of cessation counseling and with stage of change was statistically significant. Physicians who report they are currently assisting patients had higher performance and self-efficacy rating. Physicians who had participated in formal smoking cessation training had higher self-efficacy; however, their scores on the Barriers, Motivation, and Performance Scales did not differ. Further study with a representative group is encouraged.
