Note. All predictive models included 6 predictive variables: age, sex (two dummy coded variables: female, and no response to the question of sex), frequency of domestic abuse/violence, level of concern about COVID-19, and UCLA loneliness score. Change statistics were relative to the reduced model, which contained only 5 predictive variables (i.e., all variables except UCLA loneliness score).
