Abstract
The purpose of this research was to develop the Sport Commitment Questionnaire-2 (SCQ-2) and establish its psychometric properties. The SCQ-2 measures the updated Sport Commitment Model (SCM: Scanlan, Russell, Scanlan, Klunchoo, & Chow, 2013) and replaces the outdated Sport Commitment Questionnaire (SCQ) that assessed the original SCM (Scanlan, Simons, Carpenter, Schmidt, & Keeler, 1993).
Based on prior commitment research, items were generated to refine and expand the original SCQ subscales and to measure new candidate constructs to the SCM. A multiphase study was then conducted.
Phase 1 participants were 753 male/female adolescent athletes (ages 13–19 years) from six sports representing varying levels of task interdependence. Using similar methodology as Phase 1, Phase 2 assessed 982 male/female adolescent athletes.
Exploratory factor analysis of Phase 1 data revealed 13 factors: two types of commitment (Enthusiastic and Constrained) and 11 sources. Confirmatory factor analysis of Phase 2 data supported a 58-item, 12-factor structure. In addition, all subscales were internally consistent. Structural equation modeling revealed that the sources explained 81.8% of the variance in Enthusiastic Commitment and 63.9% in Constrained Commitment.
The SCQ-2 assesses the sources and types of commitment in the updated SCM. Based on several indices of fit and the composite reliabilities, psychometric support for the SCQ-2 was established.
