We also studied of sample characteristics possible differences. Studies healthy populations extensively collected; required minimum size was 50. According results, scored scales ie, Physical Anhedonia Scale (n = 23 studies, size, Cohen d 0.59, z test P < .001) Social 14, 0.44, .001). Differences virtually nonexistent measurements Magical Ideation 29, -0.01, .74) Perceptual Aberration 22, -0.08, .05). The difference larger with nonstudent older samples (d -0.19 vs -0.03, This study first one pool these scales. gender social anhedonia both nonclinical schizophrenia may relate a broader aspect interpersonal deficits. should be taken into account using instruments.
