Abstract:
Objective:The study aimed to validate the Neuroception of Psychological Safety Scale (NPSS) in terms of reliability and validity among individuals with mental disorders in China.Methods:The Study followed Brislin′s translation principles to adapt the scale into Chinese. From February to June 2023, a total of 638 hospitalized patients with mental disorders (477 with schizophrenia and 161 with mood disorders) were selected through gender-stratified simple random sampling from the Shanghai Pudong New Area Mental Health Center and the Shanghai Baoshan Mental Health Center. The Chinese version of the NPSS and the Security Questionnaire (SQ) were administered. The reliability of the scale was measured using split-half reliability and test-retest reliability. Validity was assessed through content validity, structural validity, convergent validity, and discriminative validity analyses. In addition, SQ was used as a criterion tool to test the validity of the criterion through Pearson correlation analysis.Results:The Chinese version of the NPSS contained 29 items, with total scores ranging from 29 to 145. Higher total scores indicated greater psychological safety. Item analysis showed a decider value of 10.58 to 20.80 (>3), and the correlation between items and total scores ranged from 0.579 to 0.749 (all P<0.05). The item-level content validity index (I-CVI) for the items ranged from 0.86 to 1.00, while the average scale-level content validity index (S-CVI/Ave) was 0.99. Exploratory factor analysis extracted three common factors: social participation, empathy, and bodily sensations, which is consistent with the structure of the original scale, explaining a cumulative variance contribution rate of 62.551%. Confirmatory analysis revealed a satisfactory model fit, with average variance extracted (AVE) values for the three dimensions ranging from 0.523 to 0.645, and composite reliability(CR) ranging from 0.905 to 0.938. The standard loading coefficients for the items ranged from 0.608 to 0.859, and inter-factor correlation coefficients were all smaller than the square roots of their respective AVE values. Pearson correlation analysis indicated significant positive relationships between the Chinese NPSS and SQ ( r=0.822-0.846, P<0.01). Reliability analysis showed Cronbach′s alpha coefficients of 0.903-0.959 for the total scale and subscales. After a 3-week interval, test-retest reliability (70 patients) ranged from 0.874 to 0.983, and split-half reliability was 0.869-0.969. All model fit indices met established criteria. Conclusions:The Chinese version of the NPSS demonstrates good reliability and validity, making it suitable for both research and clinical applications in assessing psychological security among individuals with schizophrenia and mood disorders.
