Abstract

The purpose of this research was to develop a causal relationship model of consuming food from polystyrene foam container and to analyze the direct effects, indirect effects and total effects from latent variables. The data were collected using the questionnaire form 280 consumers who had experience in consuming foam- packed food in Hatyai district, Songkhla province. A probability sampling method with cluster random sampling and sample selected from consumer who had experience for polystyrene foam container. The data were analyzed using descriptive statistic. A causal relationship model was analyzed by path analysis and considering the model validity by goodness of fit measures, fitted residuals matrix values and direct, indirect and total effects. The results indicated that the causal relationship model of consuming food from polystyrene foam container was consistent with the empirical data considered from goodness of fit statistic: cri-square = 62.86, df = 47, relative Chi-square = 1.33, p = .06, GFI = 0.97, AGFI = 0.93, CFI = 1.00, SRMR = 0.03 and RMSEA = 0.03. Behavioral intention was the mediator in the associations of attitude towards food consumption, subjective norm and perceived polystyrene foam food behavioral control. In addition, this research was found that intention and perceived polystyrene foam food behavioral control were all positively associated with food consumption behaviors as theory of planned behavior. All variables in the model accounted for 98 percent of the total variance in consuming food from polystyrene foam container.
