Note: CI: Confidence interval. MPQ-SC: Multidimensional Personality Questionnaire-Social Closeness subscale. CAINS-MAP: Clinical Assessment Interview for Negative Symptoms-Motivation and Pleasure subscale. CAINS-Express: Clinical Assessment Interview for Negative Symptoms-Expression subscale. Suicide ideation measured by the Brief Psychiatric Rating Scale item 4; Depression measured by the Brief Psychiatric Rating Scale item 3; Anxiety measured by the Brief Psychiatric Rating Scale item 2; Positive symptoms measured by the Brief Psychiatric Rating Scale positive symptoms subscale; Role functioning measured by the Role Functioning Scale sum of items 3 and 4; Social closeness measured by the Multidimensional Personality Questionnaire-Social Closeness subscale; Negative symptoms-MAP measured by the Clinical Assessment Interview for Negative Symptoms-Motivation and Pleasure subscale; Negative symptoms-Express measured by the Clinical Assessment Interview for Negative Symptoms-Expression subscale. Interaction term is the multiplied effects of role functioning and social closeness (Analysis 1), motivation and pleasure-related negative symptoms (Analysis 2), or expression-related negative symptoms (Analysis 3).
