Measurement invariance by sexual orientation for a measure of pandemic-related psychological distress (N=1928). Sexual orientation categories are heterosexual and sexual minority. The measure showed measurement in variance based on the criterion of ΔCFI<.01 [54] between the configural and the metric model and between the metric and the scalar model.
