title: The outcome expectancy model for areca-quid chewing behavior.
abstract: Outcome expectancies as regards areca-quid chewing played an important role in areca-quid addiction. In this study, areca-quid user expectancies will be explored. A total of 179 adolescents selected from high school completed the areca-quid chewing expectancy questionnaire and related chewing-behavior scale. Three factors (physical/emotional reward, negative consequences and social benefit) relating to areca-quid chewing behavior were explored by factor analysis and the two-dimensional model of chewing expectancy (positive-negative effect of chewing and physical-social reaction to chewing) was found using non-metric multi-dimensional scaling. The structure of the areca-quid chewing expectancy was determined for an adolescent group and the social factors involved in areca-quid chewing clearly warrant further investigation.
