Abstract
The purpose of this research was to develop a causal relationship model of consuming food from polystyrene foam containers and to validate the correspondence with empirical data based on the theory of planned behavior. The subjects were consumers who had experience in consuming foam-packed food in the Hat Yai district of Songkhla Province. A total of 280 consumers were selected by the probability sampling method with cluster random sampling and sample selection from each group by purposive sampling technique. The study instrument was questionnaires. The data were analyzed using descriptive statistics, testing the causal relationship between factors by path analysis, and considering the model validity by the goodness of fit measures and fitted residuals matrix values.
The results indicated that the causal relationship model of consuming food from polystyrene foam containers was consistent with the empirical data considered from goodness of fit statistic: cri-square = 62.86, df = 47, p = 0.060, GFI = 0.97, AGFI = 0.93, CFI = 1.00, SRMR = 0.034 and RMSEA = 0.035. The behavioral intention was the mediator in the associations of attitudes towards food consumption, subjective norms, and perceived polystyrene foam food behavioral control. In addition, this research found that intention and perceived polystyrene foam food behavioral control were all positively associated with food consumption behaviors as the theory of planned behavior. All variables in the model were accounted for 98 percent of the total variance in consuming food from polystyrene foam containers. This research can be applied to consumption behaviors of consumers in daily life as part of the campaign to reduce using polystyrene foam containers for food.
