The purpose of this study was to develop and examine the psychometric properties of two new instruments-the Domestic Gender Role Scale (DGRS) and the Domestic Gender Role Implicit Association Test (DGR IAT)-in assessing Taiwanese people’s explicit and implicit gender stereotypes regarding domestic labor. In a pilot study, 92 Taiwanese adults were recruited to obtain a sample of genderized household chores for development of the initial DGRS and DGR IAT versions. In the main study, another 149 Taiwanese people were recruited on a voluntary basis to examine the psychometric properties of the DGRS and DGR IAT. Confirmatory factor analysis of this sample indicated that the DGRS was a three-factor model. Except for the DGRS subscale for male baby boomers, the Cronbach’s alpha values and composite reliability coefficients of the three DGRS subscale scores were all above .7, indicating satisfactory reliability. The significant IAT effects of the DGR IAT indicated that it was a valid instrument for assessing implicit gender stereotypes regarding domestic labor. Its reliability coefficient was over .7 only when assessing Taiwanese baby boomers using the congruent association-first version of the DGR IAT. Moreover, the weak association between its IAT effects and the three DGRS subscale scores revealed the divergent validity of these two instruments, whereas the moderate correlation among the three DGRS subscale scores indicated its convergent validity. As newly developed instruments, the DGRS demonstrated suitable reliability and validity, whereas the DGR IAT had suitable validity but required further modifications to improve its reliability. This study provided only an initial validation of these two instruments, and further research should validate their psychometric properties using samples with diverse education levels and marital statuses.
