Here, n=21 for BPI group and n=19 for NCI group as three patients in the BPI group and four patients in the NCI group were either uncooperative or had formal thought disorder. Hence, this instrument could not be applied on them. *P<0.05 indicates statistically significant change. QOL – Quality of life; BPI – Brief psychosocial intervention; NCI – Nonspecific control intervention; SD – Standard deviation
