title: Social-cognitive determinants of nutrition behavior among supermarket food shoppers: a structural equation analysis.
abstract: A social-cognitive model of nutrition behavior (A. Bandura, 1997) was tested using structural equation modeling of data from 307 food shoppers recruited from 5 supermarkets in Southwest Virginia. The shoppers were participating in the baseline phase of an ongoing nutrition promotion program. As part of the evaluation, data were collected on the self-efficacy and outcome-expectations components of social-cognitive theory as well as on food purchases and intake. The structural analyses presented here support the social-cognitive model. Self-efficacy, physical outcome expectations, age, socioeconomic status, and number of children were important predictors of nutrition behavior among shoppers. Implications for interventions using social-cognitive variables to improve the nutritional content of food purchases and intake are discussed.
