Components/factors of the Czech version of the Physical Self Perception Profile (PSPP-CZ) among high school students [Komponenty/faktory eské verze dotazníku tělesného sebepojetí (PSPP-CZ) u st edo kolskych student ]

BACKGROUND: The physical self has been widely investigated as a determinant of exercise behaviors as well as a contributor to mental health and well being (Fox, 1997). Self esteem has been generally accepted as an important mediator of exercise and self esteem (Fox, 2000; Sonstroem, 1997). Understanding self development processes has increased in importance as self esteem and self perception components have become increasingly valued in educational, clinical and community health programs (Ferreira & Fox, 2008). In order to examine the relationships between various levels of physical activities and self perception we need to use standardized instruments to measure physical self perception among Czech teenagers. OBJECTIVE: The purpose of this study was to analyse the structure of the translated PSPP-CZ questionnaire among the population of high school students by finding components of PSPP-CZ using principal component analysis. The Physical Self Perception Profile (PSPP) has never been used in the CZ population before. METHODS: Participants were high school students from five schools representing three kinds of high schools in the Czech Republic. Of these participants, 666 were boys and 403 were girls. The average age of the participants was 17.00 (± 1.34) in boys and 16.63 (± 1.39) in girls. Participants received a test battery containing a Czech version of PSPP (Fox, 1990). PSPP has four subscales: (a) sports competence – SPORT; (b) attractiveness of the figure – BODY; (c) physical strength and musculature – STRENGTH; and (d) physical conditioning and exercise – CONDITION (Fox, 1990). RESULTS: Data were analyzed using SPSS PC 11.0. Cronbach Alpha, representing the internal consistency measure consisted of: (a) sport subscale (males = .86, females = .86); (b) physical condition subscales (males = .82, females = .85); (c) attractiveness of figure subscales (males = .78, females = .88); and (d) strength subscale (males = .87, females = .85). Initially we have found that students from Czech high schools have a different structure of self perception then the original PSPP population from England (Fox, 1990). Our findings correspond with findings among Flemish adults (Van de Vliet et al., 2002; Ferreira & Fox, 2007) where components of sport and condition were also loaded into one factor. There are clear, subtle differences in the structure of physical self perception as related to cultural and language differences. Findings of internal reliability and content validity suggest that the three subscales questionnaire can be used in the Czech population as a vali
