Einleitung

Fox and Corbin (1989) have put forward a hierarchical, multidimensional model for conceptualising self-perceptions in the physical domain. The model posits that an overall or global self-esteem (GSE) construct, as hypothesised by Rosenburg (1979), operates as a superordinate governing self-esteem in the physical domain. The physical self-worth (PSW) construct is represented by four subdomains in which individuals report their self-esteem: Sports Competence (SPORT), Physical Condition (COND), Physical Strength (STREN), and Body Attractiveness (BODY) which are related to PSW at the domain level, but not the GSE at the apex. The model has demonstrated utility in studying the organisation of self-esteem in the field of sport and physical activity (Fox, 1990). Further studies have successfully replicated the structure of Physical Self-Perception Profile (PSPP) constructs, the accompanying instrument for quantifying individual perceptions regarding self-esteem, in adults and children. Research has also indicated the PSPP variables to be related to involvement, physical fitness indicators and discriminates between high and low exercisers. Fox's (1990) model is also useful as it provides a means of discounting less significant subdomains using an importance scale to assign relative importance to given subdomains. Traditionally the importance scales have been used to discount less important subdomains and calculate discrepancy scores which demonstrate the importance of specific subdomains. However, the importance scores may also be useful in determining the relative importance of each subdomain indicator to its overall factor. The PSPP items represent the overall judgement or expectancy an individual may place on the given subdomain area. This is accompanied by an importance score which assigns importance or value to the given subdomain. This gives rise utilizing an expectancy-value paradigm to assign importance to each item prior to examining the structure of the model and relationships between the constructs. Such an expectancy-value method has been used previously in attitude research by Bagozzi (1984). The present study aims to adopt an expectancy-value paradigm by weighting each item from the PSPP with the importance score from its respective subdomain. These scores will then be used to test the multidimensional and hierarchical integrity of Fox's (1990) model. Einleitung
