Determining the Validity and Reliability Scale of Perception physical fitness

The purpose of this survey was to determine the validity and reliability of the Perceived Physical Fitness scale (PPFS). In the first stage, 600 people filled in the questionnaire in order to determine the compute detection factor analy sis. In the second stage, 480 people completed it for determining the compute confirmatory factor analysis, and in the last stage 130 people filled it twice, with a two-week time lap. The measurement device was Abadie ʹs Perceived Physical Fitness scale (PPFS) (1998) with 12 questions and 4 subscales. For determining compute detection factor analysis, compute confirmatory analysis, and internal reliability and time reliability, the researcher respectively used main factor analysis, structural equation model, Cronbach alpha and Pearson correlation. Findings showed that PPFS has a suitable structural reliability with variance percentage in these 4 factors: physical conditions (22 .18), muscular flexibility (13.14), muscular conditions (11.6) , body composition (12.11) and cumulative variance percentage (59.03). The results also showed that the questionnaireʹs internal reliability (0.84) and time reliability (0.80) and its subscales are acceptable. Hence, it can be concluded that the Persian versions of PPFS has the suitable reliability and validity and can be used as an acceptable device for studying the purposes, comparing with actual physical conditions and other functional purposes for athletes and researchers in educational, sports and research environments.
