This article presents research ideas for further study of the role of multicultural counseling competencies in counseling and psychotherapy. Research recommendations revolve around the ideas of including the client in the assessment of counselors' multicultural counseling competencies and of studying multicultural counseling competencies in relation to process and outcome indexes of counseling.Este articulo presenta ideas para avanzar la investigacion y estudio del papel de las competencias multiculturales en la consejeria y la psicoterapia. Las recomendaciones de esta investigaci6n se basan en dos ideas. La primera es incluir a 10s clientes en la evaluation de la competencia multicultural de sus consejeros, la segunda es el estudio de competencias multiculturales en relacion al proceso y resultados de la consejeria. ounselors and researchers in the mental health field have become increasingly aware of the role of cultural factors, such as race, ethnicity,
The purpose of this study was to access current medication usage by HIV/AIDS patients and its effects on dental caries and on unstimulated salivary flow rates. Thirty females and 127 males (mean age = 39.6 +/- 7.4 years), of whom 46% were White/Non-Hispanic, 39% African-American, and 15% Hispanic, were examined and interviewed at the Bering Dental Clinic, Houston, Texas. The mean time in years after seroconversion was 5.4 +/- 4.1. Calibrated examiners performed dental caries examination (DMFS) with dental explorers and bitewing radiographs. Interviews were carried out with pretested questionnaires, and medication usage was assessed by illustrative examples of HIV/AIDS medications. Salivary flow rates were determined gravimetrically (mL/min). Bivariate analysis and analysis of variance (ANOVA) were used to analyze the data. Because there were no race or gender effects on dental caries outcome variables or salivary flow rates, separate logistic regression models for medication usage were generated, which were adjusted for age and CD4+ cell counts. Patients who, currently, were receiving antiretroviral therapy (ART) had a lower occurrence of dental caries than patients not taking these medications. An unexpected finding in the lower caries rate group was a decrease in salivary flow rates, which was a probable oral side effect of ART. It appears from this cross-sectional study that systemic medication for the management of HIV disease has no significant detrimental effect on the dentition.
Sample size calculations for a group-randomized trial (GRT) require an estimate of the expected intraclass correlation coefficient (ICC). However, few ICC estimates from GRTs in HIV/AIDS research have been published, leaving investigators with little data on which to base expectations. We used data from a multi-country study to estimate ICCs for variables related to physical and mental health and HIV risk behaviors. ICCs for perceptions of physical and mental health tended to be higher than those for HIV risk behavior variables, which were higher than ICCs for CD4 count. Covariate adjustment for country and socio-demographic variables reduced most ICC estimates. For risk behavior variables, adjustment for country and socio-demographic variables reduced ICC estimates by as much as 84 %. Variability in ICC estimates has important implications for study design, as a larger ICC reduces power. ICC estimates presented in this analysis will allow more precise sample size estimates for future GRTs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
