The purpose of this study is to examine the attitudes of direct care workers (DCWs) in group homes towards PWDs. This study also investigated DCWs' demographic and other variables on their attitudes towards PWDs. The scale of attitudes towards disabled persons (SADP) questionnaire was administered to a purposive sample of 108 direct care workers in four group homes companies in the Lansing area. Of the 108 participants, 104 responded, but six participants were dropped from the studies because they did not answer most of the questions, resulting in 98 usable questionnaires, a 90 percent response rate. Quantitative analysis, using descriptive statistics to investigate DCWs' attitudes and general linear model to investigate the effects of DCWs' demographic and other variables on their attitudes towards PWDs. Regarding DCWs' attitudes, both their general and specific attitudes, that is DCW's optimistic, behavioral misconception, and pessimism attitudes, were investigated. For variables that had effects on DCWs' attitudes, comparison were made regarding differences within the variables to see different categories' or groups' effects. Results show that DCWs in the group homes had moderate positive attitudes towards PWDs, in both their general and specific attitudes. Result regarding DCWs' demographic and other variables' effects on DCWs' attitudes shows that some variable had effects while others did not. Comparison within variables shows significant differences between and among some of the groups, indicating that some variable had more positive or negative attitudes than others, and non significant differences in others. (1) The overall attitudes of DCWs towards PWDs were general positive. (2) Training needs, knowledge about disability, and contact with PWDs and had an impact on their overall attitudes towards PWDs. (3) DCWs' attitudes towards PWDs in relation to the SAPD subscales were positive for the SADP's three subscales. (4) For training needs, in all the scales, only the means of those whose training needs were a combination of directly working with clients (DWC), learning about disability (LAD), and helping individual with disability (HIWD) were significantly different from the means of all the other groups. (5) Contact had effect on the SAPD scale, and its subscales, 2 and 3. All of the subtypes of "contact" positively affected the attitudes of DCWs in the SAPD scale. (6) For "population DCWs worked with" in subscale 2, those who worked with brain injuries (BI) and those who worked with a combination of those with mental retardation (MR) and psychiatric disability (PD) had negative attitudes. (7) For "knowledge about disability," all the categories under knowledge had positive effects towards PWDs. There are implications for training and research. Increasing DCWs' level of knowledge about disability can help their attitudes towards PWDs. Research can focus on the training needs of PWDs since training needs have the potentials of affecting DCWs' attitudes. Also, research can focus on the type of contact and how they affect DCWs' attitudes. Furthermore, researchers should replicate this study with different DCWs to see whether they can find similar results as this study, and they can focus on which type of knowledge can positively impact DCWs' attitudes.
