ABSTRACT
Objective:To develop a suitable solitude behavior scale for short version(SBS-S).Methods:A total of 2 484 valid data were collected from college students in Tianjin city and Shandong province.Based on the exploratory structural equation model(ESEM) and generalized partial credit model(GPCM) of item response theory, the SBS-S was developed.A total of 100 college students in Guizhou province were tested twice at intervals of two months to calculate the test-retest reliability of the SBS-S.R language Mplus 8.0 and SPSS 24.0 software were used for the data analysis.Results:According to the results of ESEM and GPCM model, 18 items were deleted. After deleting the above questions, 16 items (four items under each dimension) and four dimensions(positive solitude, eccentricity, social avoidance and loneliness) were retained. The coefficient of Cronbach's α was above 0.75. The results of confirmatory factor analysis showed that the structure model of the SBS-S was fitting well, and the index was ( χ2/ df=4.74, TLI=0.92, CFI= 0.95, SRMR =0.05, RMSEA=0.06). According to the results of SPSS, the test-retest reliability was above 0.60.Big-five persondlity, social support and self-esteem were regarded as criterion related validity. The results showed that positive solitude had positive correlations with extraversion, conscientiousness, agreeableness, openness and self-esteem( r=0.07, 0.25, 0.15, 0.26, 0.09, all P<0.05). Eccentricity and social avoidance had negative correlations with extraversion, conscientiousness, agreeableness, social support and self-esteem( r=-0.25, -0.22, -0.45, -0.16, -0.36, all P<0.05; r=-0.26, -0.09, -0.06, -0.18, -0.36, all P<0.05), and had positive correlations with neuroticism( r=0.25, 0.32, both P<0.05). Loneliness had negative relation with extraversion, conscientiousness, agreeableness and self-esteem( r=-0.08, -0.11, -0.08, -0.33, all P<0.05), and had positive correlations with neuroticism( r=0.33, P<0.05). Conclusion:The SBS-S has good psychometric characteristics and can be used to evaluate the solitude behavior of individuals.
