This study intended to validate and develop the Physical Educators' Intentions Toward Teaching Individuals with Disabilities II Preservice Survey (PEITID-II-PS; So, Tripp, & Rizzo, 2007).
Method
A total of 245 (192 males and 53 females) middle school PE teachers in Korea participated in this study. Each participant completed the Korean version of the PEITID-II-PS, consisting of 30 items (instead of 35 items of the original PEITID-II-PS); three items for intention (I), three for attitude toward the behavior (ATB), three for subjective norm (SN), three perceived behavior control (PBC), six behavioral beliefs (Ab), six normative beliefs (SNb), and six control beliefs (PBCb). All items use a 7-point Likert-type scale ranging from 1 (strongly disagree) to 7 (strongly agree). To compute an indirect measure of Ab, SNb, and PBCb in accordance with an expectancy-value model as described in the TpB (Ajzen, 2004), the belief strength was multiplied by outcome evaluation, and the resulting products were summed over all accessible behavior outcomes.
Analysis/Results
The results supported for the psychometric properties of the Korean version of the PEITID-II-PS. Internal consistency reliabilities using Cronbach's alpha (Ą) coefficients ranged from .83 to .95; I (.95), ATB (.92), SN (.95), PBC (.89), Ab (.83), SNb (.87), and PBCb (.93). EFA produced seven factors of the Korean version of the PEITID-II-PS, accounting for 75.7% of the total variance. Confirmatory factor analysis (CFA) revealed a relatively high adequate fit of the hypothesized model of the Korean version of the PEITID-II-PS to the data, Normed c2 =1.80, GFI=.92, NFI=.94, TLI=.96, CFI=.97, and RESEA=.06. A Structural Equation Model (SEM) analysis found a relatively adequate fit of the model to the data; Normed c2 =3.65, GFI=.84, NFI=.88, TLI=.90, CFI=.91, and RESEA=.09. Based on the results of the structural equation model analysis, the path coefficients (a) were examined to determine causal effects among factors of the Korean version of the PEITID-II-PS. Normative beliefs had positive effects on subjective norm (&beta =.53, t=7.31, p <.001). The subjective norm (&beta =.41, t=7.00, p<.001), attitude toward the behavior (&beta =.36, t=6.04, p<.001), and perceived behavior control (&beta =.26, t= 4.46, p<.001) had positive effects on intention toward teaching individuals with disabilities. However, the control beliefs showed a negative effect on the perceived behavior control (&beta =-.17, t=-2.40, p<.05).
Conclusions
The results indicated the potential usefulness of the Korean version of the PEITID-II-PS in assessing Korean physical education teachers' intention toward teaching students with disabilities.
