This study tested the applicability of the theory of planned behavior (TPB) on gambling intention and involvement in a representative Chinese sample in Macao, recruited by a random residential number dialing method. We successfully interviewed 685 respondents, with about one-third of them reporting that they had participated in gambling activities during(More)
OBJECTIVES We studied the predictive impact of family satisfaction, marital status, and functional impairment on the trajectories of life satisfaction over the first 5 years following medical treatment for traumatic spinal cord injury, burns, or interarticular fractures (total N = 662). It was anticipated that fewer functional impairments, being married,(More)
Despite the high availability of offline gambling in Macao, China, Internet gambling may remain attractive to many gamblers due to its anonymity and convenience. Given the scarcity of relevant research, this study aims to not only investigate the public attitude and prevalence of Internet gambling but also identify the demographic and psychological(More)
An excessive, problematic gambling pattern has been regarded as a mental disorder in the Diagnostic and Statistical Manual for Mental Disorders (DSM) for more than 3 decades (American Psychiatric Association [APA], 1980). In this study, its latest prevalence in Macao (one of very few cities with legalized gambling in China and the Far East) was estimated(More)
We studied the predictive impact of proxy ‘‘outsider’’ reports, injury type, and functional independence on trajectories of happiness over the first 5 years following medical treatment for a traumatic spinal cord injury, brain injury, severe burns or interarticular fractures (total N = 1,271). It was anticipated that lower functional independence and(More)
Although previous research has discussed an effect size estimator for partially nested cluster randomized designs, the existing estimator (a) is not efficient when used with primary data, (b) can be biased when the homogeneity of variance assumption is violated, and (c) has not yet been empirically evaluated for its finite sample properties. The present(More)
In conventional structural equation modeling (SEM), with the presence of even a tiny amount of data contamination due to outliers or influential observations, normal-theory maximum likelihood (ML-Normal) is not efficient and can be severely biased. The multivariate-t-based SEM, which recently got implemented in Mplus as an approach for mixture modeling,(More)
This article attends to recent discussions of validity in psychometric research on human life history strategy (LHS), provides a constructive critique of the extant literature, and describes strategies for improving construct validity. To place the psychometric study of human LHS on more solid ground, our review indicates that researchers should (a) use(More)
Background and aims Internet gaming disorder (IGD) imposes a potential public health threat worldwide. Gaming motives are potentially salient factors of IGD, but research on Chinese gaming motives is scarce. This study empirically evaluated the psychometric properties of the Chinese version of the Motives for Online Gaming Questionnaire (C-MOGQ), the first(More)
The research literature has paid little attention to the issue of finite population at a higher level in hierarchical linear modeling. In this article, we propose a method to obtain finite-population-adjusted standard errors of Level-1 and Level-2 fixed effects in 2-level hierarchical linear models. When the finite population at Level-2 is incorrectly(More)
