Note: Final columns provide the results of the post-hoc Scheffe’s pairwise comparisons (with corresponding significance levels: * < .05; ** p < .01; *** p < .001) where ‘a’ denotes the “No suicidal ideation” group (i.e. HDRS item-3 score = 0); ‘b’ denotes the “Life not worth living” group (i.e. HDRS item-3 score = 1) and ‘c’ denotes the “Thoughts of death or Suicidal ideation” group (i.e. HDRS item-3 score >1). SOFAS = Social and Occupational Functioning Assessment Scale; HDRS = Hamilton Depression rating Scale; BPRS = Brief Psychiatric Rating Scale; K-10 = Kessler-10; AUDIT = Alcohol Use Disorders Identification Test.
