Introducing the Questionnaire of Commitment to Exercise

Abstract

The present study aimed to make and establish psychometric features of an exercise commitment questionnaire. The primary 35 questions were administered to 210 staffs working in Isfahan Steel Company, 120 males and 90 females. Subjects had 10 years of work experience in the company and were randomly selected using stratified sampling method. Principle component analysis and Varimax rotation were used to measure its construct validity. Finally, 25 questions were extracted with more than 0.5 loading factor indicating the validity of the instrument. Accordingly, a four-factor construct was made, being capable of explaining 58.4 percent of total variance by the use of principle component method. Results of the confirmatory factor analysis yielded features indicating positive fitness of the confirmatory analytic model of the commitment to exercise questionnaire. Also by using internal consistency reliability was calculated with Cronbach's alpha and the coefficient was 0.873 showing strong reliability. Overall, based on the satisfactory reliability and validity, this study shows that commitment to exercise questionnaire serves as a suitable measuring tool for the future research.

Effect of Special Cognitive-Behavioral Intervention on Commitment to Exercise and Mental Health

“…The Cronbach's alpha obtained was 0.873: this validated the reliability of the questionnaire by using internal consistency. This, in turn, generally indicated that the commitment-to-exercise questionnaire with satisfactory reliability and validity indices can be used as a suitable instrument for evaluation of commitment to exercise by psychologists and counselors in cognitive-behavioral interventions (Derakhshanpoor, Vaez Mousavi, & Taheri, 2016).…”
