students with disabilities, average-achieving students, high-achieving students) for the ATDP
(Yuker et al.
Each of the 20 items on the ATDP Scale are purported to reflect statements suggesting the similarities or differences between people with and without disabilities.
The ATDP Scale was selected for the study because of ease of administration and it had been carefully studied as an instrument measuring generalized attitude toward people with disabilities (1).
To test the effects of the pre-test and the educational intervention, we conducted a two-way multivariate analysis of covariance (MANCOVA) using post-test scores for the ATDP and the KAPWD, and gender, self-disability, family disability, friend disability, and prior experience as covariates.
In an effort to assess whether the participants retained their increased knowledge and improved attitudes after the intervention, we compared the ATDP and KAPWD scores for Groups 1 and 2 using paired-sample t-tests.
Next, the completed surveys were paired by participant code, and the results of both surveys were tabulated according to the scoring directions provided in the ATDP
manual, and the aggregate scores for each participant's pre-and post-test calculated.
24) The ATDP
scale continues to be one of the most used measures of attitude toward persons with disabilities.
This finding appears consistent with existing research that indicates persons who have parents with disabilities do not demonstrate higher scores on the ADTR With the only significant interaction effect seen in students with prior contact with a 'Professor' with a disability, the differences in ATDP
scores appear to be influenced by perceived levels of power.
Antonak and Livneh (1988) likewise reported that on the most commonly used measure, the ATDP
, females displayed greater acceptance of physical disability than did males.
Despite the move to better understand the complexities of attitudes toward persons with disabilities, the ATDP
and the SADP are both self-report measures that examine attitudes toward persons with disabilities as a group.
In the general context, Yuker and Block (1986) reported the mean ATDP
score for American subjects based on the average of 29 studies was 117.
The post hoc comparison between 20+ years and 5-9 years is significant (Factor I and Factor II), and between 20+ years and 5-9 years and 5 years is significant on ATDP
