Abstract
BACKGROUND: Over 600 million people chew betel nut worldwide and the behavior is classified by the World Health Organization (WHO) as a Group 1 carcinogen. Having a reliable and valid scale of reasons for chewing betel nut that can be used consistently across gender for both chewers and ex-chewers will assist practitioners to create culturally appropriate risk reduction and cessation programs and address an important public health concern.Purpose/ Objectives: We sought to: 1) examine factor structure, reliability, and validity of the Reasons for Chewing Scale (RBCS) for ex-chewers; 2) examine the influence of social-cultural factors on chewing behaviors; and 3) examine if measurement invariance (MI) of the RBCS held consistently across gender groups. METHODS: A Confirmatory Factor Analysis (CFA), a multigroup CFA for testing measurement invariance (MI), and Structural Equation Modeling (SEM) were applied to the RBCS using a convenience sample of (N = 223) of ex-chewers from Guam. RESULTS: The majority of the items in the RBCS were found to be moderately or strongly correlated to each other. The CFA model fit the ex-chewers' data well and the model suggested that the RBCS was found to be reliable and valid. The multi-group CFA showed this scale functions equivalently for both male and female groups.Conclusions/Importance: The RBCS is a valid and reliable measure that is invariant across gender and type of ex-chewer.
