Note. ISMI = The Internalized Stigma of Mental Illness Scale; MANSA = The Manchester Short Assessment of Quality of Life; RES = Rosenberg Self-Esteem; M = mean; SD = standard deviation; df = degree of freedom. Two-way analysis of variance results for effects of group, attendance, and the interaction.

df = (1,218).

df = (1,216).

df = (1,215).

Differences between the control and treatment groups.

Differences between those who did and didn’t complete Time 2 assessments.

Interaction between “groups” and “attendance”.
