The Sports Commitment Questionnaire-2 (SCQ-2) has been developed and validated to investigate athletes&rsquo; 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.<br> <b>Objectives</b>. This study aimed to evaluate the psychometric properties of the Sports Commitment Questionnaire-2 (SCQ-2) among Malaysian racquet sports athletes.<br> <b>Methods.</b> This is a cross-sectional study, a total of 416 players (245 males/ 171 females, &micro; age=29.94&plusmn;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).<br> <b>Results.</b> 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, X&sup2;/df=2.14). Discriminant validity also met the suggested cutoff value (< 0.90). whereas&nbsp; 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.<br> <b>Conclusion.</b> The SCQ-2 showed adequate validity and reliability which enable sports practitioners to access athletes&#39; commitment in a sports context.</span></span></span></span></span></div> Constrained Commitment, Enthusiastic Commitment, Racquets Sports Athletes, Sports Commitment Model, Sports Enjoyment. 0 0 http://aassjournal.com/browse.php?a_code=A-11-2241-1&slc_lang=en&sid=1 Eng Wah Teo vteo2@um.edu.my 100319475328460014253 100319475328460014253 Yes Faculty of Sport and Exercise Sciences, University of Malaya, Kuala Lumpur, Malaysia Arthur Ling ling_wei87@hotmail.com 100319475328460014254 100319475328460014254 No Faculty of Sport and Exercise Sciences, University of Malaya, Kuala Lumpur, Malaysia Ngien Siong Chin ngiensiong@gmail.com 100319475328460014255 100319475328460014255 No Department of Physical Education, Institut Pendidikan Guru Kampus Batu Lintang, Kuching, Malaysia Remco Polman remco.polman@qut.edu.au 100319475328460014256 100319475328460014256 No Institute of Health and Wellbeing, Federation University, Ballarat, Victoria, Australia Kanagarajah Rarujanai rs_kanna85@yahoo.com 100319475328460014257 100319475328460014257 No Department of Physical Education, Institut Pendidikan Guru Kampus Tun Abdul Razak, Kota Samarahan, Malaysia Lee Sze Kho kholeesze12030055@gmail.com 100319475328460014258 100319475328460014258 No Department of Physical Education, Institut Pendidikan Guru Kampus Tun Abdul Razak, Kota Samarahan, Malaysia
