Integration of the Theory of Planned Behavior and Transtheoretical Model of Change for Prediction of Intentions to Reduce or Stop Alcohol Use among Thai Adolescents.

BACKGROUND: Alcohol use among Thai adolescents has been increasing over the past few decades, and efforts to control consumption by underaged youth have proven largely ineffective. Objectives: This study tested components of the Theory of Planned Behavior (TPB) and Readiness to Change, based on the Transtheoretical Model (TTM), to identify useful constructs for developing alcohol use interventions for youth. Methods: A sample of 825 Thai student drinkers (65% female), between the ages of 14 and 19, were recruited in Bangkok, Thailand. Hierarchical regression analyses were used to test components of the TPB and Readiness to Change as predictors of intention to reduce/stop alcohol use while controlling for age, gender and alcohol use. Results: The model accounted for 58% of the variance of intentions. The TPB components accounted for a significant increase in variance beyond that explained by age, gender and alcohol use, ΔR2 = .23, p < .001; Perceived Behavioral Control (PBC) was the strongest predictor (ß =.41, p < .001), followed by Attitudes (ß=.13, p < .001), and Subjective Norms (ß =.09, p = .002). Readiness to Change composite scores (ß=.54, p < .001) were added last and accounted for a further significant increase, ΔR2 = .24, p < .001. Conclusions: The findings suggest that interventions should assess Readiness to Change and utilize effective processes in facilitating change at each stage. Other suggestions are to improve participants' PBC and to further examine the role of specific social norms and attitudes regarding perceived benefits and disadvantages of alcohol use.

Validation of the Coping with Discrimination Scale in sexual minorities.

The Coping With Discrimination Scale (CDS) shows promise as a self-report measure of strategies for coping with racial discrimination. To assess the psychometric properties of the measure for use with sexual minorities (i.e., gay, lesbian, bisexual, or GLB persons), a nonprobability sample of 371 GLB adults completed the instrument along with several standardized, self-report measures. Confirmatory factor analyses supported the five-factor structure of the original scale with the exclusion of five items. Adequate internal consistency reliability was found. Internalization, drug and alcohol use, and detachment subscales were correlated positively with measures of psychological distress and negatively with a measure of life satisfaction, providing evidence of construct validity. The education/advocacy and resistance subscales were largely unrelated to concurrently administered validation measures, consistent with prior findings. Coping strategy use varied as a function of primary sources of social support. The CDS appears to be a psychometrically sound measure of several discrimination coping strategies for use with sexual minorities.

The attitudes toward transgendered individuals scale: psychometric properties.

Gay, lesbian, bisexual, and transgendered individuals are sexual and gender minorities subject to stigma in a heteronormative culture with binary gender role norms. Although much research has examined sexual stigma in the form of homophobia, or negative attitudes and reactions to homosexuals and homosexuality, little is known about the stigma experienced by transgendered individuals. Transgendered people are those whose gender identity (sense of oneself as a man or a woman) or gender expression (expression of oneself as a man or a woman in behavior, manner, and/or dress) differ from conventional expectations for their physical sex. Although a scale exists to measure transphobia or negative attitudes and reactions to transgendered individuals, it includes items tapping into overt behavioral expression of this stigma, or gender-bashing, and fails to identify or define transgendered persons as the attitudinal target of the items. A new scale was developed and evaluated in an effort to assess transgender-related stigma, separately from discrimination and violence, among members of the general population. Using two separate samples of college students ranging in age from 18-64 years, exploratory (N = 134) and confirmatory factor analyses (N = 237) were performed. The resulting 20-item, self-report measure demonstrated a single-factor structure, high internal consistency reliability, and evidence of convergent and discriminant construct validity.
