The revised Personal Lifestyle Questionnaire for early adolescents.

The purposes of this study were to revise the Personal Lifestyle Questionnaire (PLQ), a measure of positive health practices, for use with early adolescents and to provide evidence of reliability and validity for the revised PLQ instrument. The sample consisted of 224 seventh and eighth graders who responded to the revised PLQ and instruments measuring three theoretically relevant variables. Relative to the revised PLQ, content validity was established, construct validity was determined by support of three hypotheses derived from theoretical propositions, and a two-factor solution was accepted in factor analysis procedures using principal components analysis with Varimax rotation. Acceptable reliabilities were obtained on the total revised PLQ and Factor 1; the reliability for Factor 2 fell slightly below the acceptable standard.
