Psychometric properties of the self-control schedule: Thai version

The psychometric properties of the Thai version of the Self-Control Schedule (SCS), a measure of learned resourcefulness, were examined. Data were collected from 77 pregnant women who were HIV positive and 103 pregnant women who were HIV negative. Back-translation was completed, and agreement between the two content experts as determined by the Content Validity Index was 86%. To assure the equivalence of the translated SCS, English and Thai versions were completed by 16 bilinguals, and the two versions were found to correlate highly (r=.95; p<.01). Internal consistency reliability for the Thai version of the SCS was.81. Confirmatory factor analysis was used to establish construct validity. The results suggest that the Thai version of the SCS has promise for use with pregnant Thai women; however, modification of some items would improve its understandability and cross-cultural applicability. Further psychometric testing in larger and more diverse samples is recommended.
