This paper details revalidation of a higher-order (HO) version of the Parental Attitudes Toward Inclusiveness Instrument (PATII), measuring parents' attitudes toward curricular inclusivity of gender and sexuality diversity. The 48-item scale includes two HO factors: Supports and Barriers, and one first-order factor: Parental Capability. Responses from parents of government-school students (N = 2093) provided evidence for scale reliability, validity, and measurement invariance.
Keywords: Construct validity; education; exploratory structural equation modeling; gender and sexuality diversity; parents.
