| Popis: | The effects of basic psychological need satisfaction from the self-determination theory on relationships within the theory of planned behavior (TPB) were examined in a prospective study. It was hypothesized that need satisfaction would moderate the relationship between intention and behavior and between intention and its proximal determinants. Participants (n = 250) completed measures of the TPB and psychological need satisfaction with respect to restrictive dietary behaviors. Moderated multiple regression analyses indicated that each psychological need moderated the effects of subjective norms on intention. Results suggest that individuals with high psychological need satisfaction tend to base their intentions on subjective norms to a greater extent compared with individuals with lower psychological need satisfaction. Epidemiological research suggests that rates of cardiovascular disease and obesity in industrialized nations are rising sharply and reaching epidemic proportions (World Health Organization, 1999). As a consequence, there is greater impetus to further understand the psychological antecedents and mechanisms underpinning the self-regulation of dieting behavior. Policymakers and health strategists have turned to theoretical models developed by social psychologists in search of models to understand these influential factors and processes (Hagger & |
