Abstract
Purpose: Although deficits in social cognition (SC) had been recognized as a hallmark of schizophrenia, quality data in Indian context were limited. The purpose of the current research was to determine the demographic and clinical correlates of SC in schizophrenia. Methods: Between February 2014 and January 2015, a case-control study was conducted in Chhattisgarh, India, among 100 paranoid schizophrenia patients (ICD-10) from two psychiatric hospitals and 100 neighborhood-based healthy (28-item General Health Questionnaire) controls. After obtaining signed consent, SC was assessed among 20-35-year-old, high school or more educated subjects ensuring eligibility for appropriate scales. Results: Patients had poorer social knowledge (adjusted-beta-coefficient [AC] = -4.89 [-6.32, -3.45]) and lower predicted mean score for internal attribution of negative event (AC: -0.72 [-1.17, -0.27]). Nonrecognition of facial expressions especially for anger (adjusted-odds-ratio [AOR] = 3.50 [1.17, 10.51]), surprise (AOR = 2.91 [1.36, 6.25]) and fear (AOR = 2.35 [1.11, 5.01]) was more common among cases. Wrong recognition of expressions was less likely among females (for surprise: AOR = 0.35 [0.13, 0.93]) and educated (for sadness: AOR = 0.11 [0.02, 0.58]) but more common among wealthy (for surprise: AOR = 4.58 [1.22, 17.19]) and urban (for fear: unadjusted odds ratios = 4.30 [1.53, 12.03]) subjects. If recognized expressions correctly, females were more likely to perceive higher intensity of anger (AOR = 4.30 [1.80, 10.29]) and happiness (AOR = 4.22 [1.66, 10.72]). Higher intensity was perceived by more educated subjects regarding anger (AOR = 2.57 [1.04, 6.34]) but not for happiness (AOR = 0.09 [0.01, 0.79]). Unmarried/divorced/separated perceived happiness (AOR = 2.86 [1.02, 7.97]) with more intensity while those in joint families perceived sadness (AOR = 2.80 [1.22, 6.41]) and fear (AOR = 2.28 [1.01, 5.16]) with more intensity. Conclusion: A significant impairment in SC was observed among paranoid schizophrenia cases in Chhattisgarh, India. Intervention and further research addressing identified issues of SC need to target specific subpopulations, among schizophrenia patients.
