Psychometrics’ Properties of Sports Commitment Questionnaire-2 among Racquet Sports Athletes in Malaysia

Sports psychologists believe sports commitment is important to indicate the desire to continue or cease participation in sports from a psychosocial perspective. The Sports Commitment Questionnaire-2 (SCQ-2) has been developed and validated to investigate athletes’ commitment in sports settings in Western countries but not in Malaysia. Hence, it is essential to establish instrument validity before being widely used in Malaysia, especially among athletes.

This study aimed to evaluate the psychometric properties of the Sports Commitment Questionnaire-2 (SCQ-2) among Malaysian racquet sports athletes.

This is a cross-sectional study, a total of 416 players (245 males/ 171 females, µ age=29.94±11.47) completed the SCQ-2 (Scanlan et al., 2016) consisting of 58 items measuring ten factors and two dimensions of sports commitment. We examined the psychometric properties of SCQ-2, by conducting Confirmatory Factor Analysis and examined discriminant validity and composite reliability (CR).

Initial fit indices of the hypothesized measurement model did not achieve satisfactory fit. But, after further model modification i.e., deleting 3 items resulted in good data fit (CFI=0.90, RMSEA=0.05, TLI=0.90, X²/df=2.14). Discriminant validity also met the suggested cutoff value (< 0.90). whereas  CR values were acceptable for the subscales ranging from 0.77 to 0.89. Convergent validity (AVE, ranging from 0.50 to 0.58) and discriminant validity (<0.90) were also established.

  The SCQ-2 showed adequate validity and reliability which enable sports practitioners to access athletes' commitment in a sports context.
