The Zest For Work Scale For Referees: Validity and Reliability Study-ZWSR

The aim of the study is to develop the Zest Scale for Referees (ZWSR). The study group was formed by convenient sampling method. The sample of the study is consisted of a group of 314 referees who actively served as referees during the 2016-2017 season. These referees are consisted of 36% (n:113) basketball, 33% (n:106) soccer, 5% (n:16) wheelchair basketball, %10 (n:31) hentball, 6% (n:18) tennis referees. 14% (n:44) of the referees who participated in the research are female and 86% (n:270) are male referees. The average age of the referees participating in the study is 26, and the average of refereeing experience is 6 years. The scale was administered to the referees participating in the survey as face-to-face at a time when there were no competitions. The analysis of the data was conducted using SPSS 21 and AMOS programs. For construct validity of the scale, principal component analysis and varimax rotation techniques were used. The Pearson moment correlation coefficient and the t-test were used to determine the criterion validity and item discrimination of the (ZWSR). The Referee Self-Efficacy Scale (REFS) developed by Kara？am and Pulur (2017) was used for the criteria validity of ZWSR. As a result of the exploratory factor analysis, it was observed that the total explained variance was 50.59% and the items were clustered under a single factor. The alpha internal consistency coefficient for the scale was .83 and the KMO value was .85. The DFA analysis of the scale showed c2/sd = 1.636 RMSEA = .07, CFI = .96, GFI = .94, AGFI = .90, RMR = .01 and NFI = .92. The item total correlations of the ZWSR varied between .56 and .84, and t-values were significant in all items (p <.001). For the criterion validity, the correlation between ZWSR and REFS total scores, and the subscales of REFS varied between .52 and .62, and these coefficients were significant at p = .01 level. The results show that the ZWSR scale is valid and reliable in measuring the level of zest of the referees
