Abstract
An idiographic repertory grid method of measuring self-concept was used in a nomothetic design to study the relation between smoking behavior and four components of self-concept: real self, ideal self, social self, and ideal social self. Personal constructs were elicited from 32 smoker and 32 nonsmoker male and female college students. Differences between smokers and nonsmokers on all four components of self-concept supported the criterion-related validity of the measures. Implications were discussed for the assessment method and clinical practice.
