The aim of this study was to test the validity and reliability of the short form to revise for children and adult athletes of the Performance Perfectionism Scale For Sport (PPS-S). The study was carried out on two groups, 200 adults and 294 children.
First group (PPS-AS) EFA showed that the factor load values of the items varied between .52 and .85 and covered 52.06 % of the total variance. Second group (PPS-CS) EFA showed that the factor load values of the items varied between .35 and .71 and covered 32.34 % of the total variance. The CFA results showed that the Turkish version of the both scale (PSS-AS and PSS-CS) were also consisted of single sub-dimensions, PPS-AS a total of 6 items and PPS-CS a total of 5 items, the model (PSS-AS) reached perfect and adequate fit indexes (χ2/sd = 2.21, RMSEA = 0.07, GFI = 0.97, AGFI = 0.92, NFI = 0.96, CFI = 0.97, AGFI = 0.92) and the model (PSS-CS) reached perfect fit indexes (χ2/sd = 1.50, RMSEA = 0.04, GFI = 0.99, AGFI = 0.97, NFI = 0.98, CFI = 0.99, AGFI = 0.97) after with the necessary modification procedures. Reliability coefficients of both scales ranged from 0.79 (PPS-AS) and 0.74 (PPS-CS). Split-Half correlation coefficients of both scale were found for PPS-AS (0.83-0.80) and for PPS-CS (0.88-0.82). The mean variance (AVE) and composite reliability (CR) values were calculated [(PPS-AS for AVE (0.62), CR (0.86); PPS-CS for AVE (0.64), CR (0.85)]. Results finally indicated that it can be said that PPS-YS is an instrument that has sufficient psychometric properties can be used determine levels to performance perfectionism of athletes aged between 18-52. It can be said that PPS-CS is an instrument that has sufficient psychometric properties can be used determine levels to performance perfectionism of athletes aged between 7-17.
