To evaluate the reliability and validity of the Chinese version of the Social Connectedness Scale-Revised(SCS-R) in order to provide correct way of its application among psychiatric patients.
A convenience sampling method was employed to select 345 patients with different types of mental disorders from K Hospital in Shenzhen. The patients’ general demographic information and disease conditions were collected, and Chinese version SCS-R was used to assess their social connectedness status. Cronbach α and split-half reliability were calculated to evaluate the reliability of SCS-R. Structural, convergent, discriminant, and discriminative validity were performed to measure the validity. The sample was randomly divided into half, exploratory factor analysis was used to explore the internal dimension of SCS-R, and confirmatory factor analysis was used to compare the scale structure explored and compared with the other three existing scale structures.
The Cronbach α coefficients for the total scale, social connectedness, non-social connectedness, and integration sense sub scales were 0.922, 0.904, 0.887 and 0.740, respectively. The split-half coefficients were 0.908, 0.918, 0.875 and 0.760, respectively. Exploratory factor analysis identified a three-factor structure, and confirmatory factor analysis showed that the scale structure developed in this study had a better fit than the other three and could explain 62.253% of the total variance. Both convergent validity and discriminant validity had success rates of calibration experiment as 100%. The correlation coefficients indicated good discriminative validity for the three dimensions of the scale.
The Chinese version of the SCS-R scale has shown good reliability and validity among psychiatric patients, making it suitable for evaluating the social connectedness of this population.
