ABSTRACT

Objective:

To evaluate the reliability and validity of the Adolescents' Quality of Life Scale in left-behind children to provide a reliable measurement tool for the study of the quality of life of left-behind children.

Methods:

Six schools (three primary schools and three secondary schools) were selected in the Qianjiang District of Chongqing City by the purpose sampling method. A total of 1 276 students in the 4-9 grades were selected. One week later, one of the primary and secondary schools was retested respectively.

Results:

The 23rd item was deleted from the Adolescents' Quality of Life Scale. Every factor load of 38 items was greater than 0.4, and the cumulative variance contribution rate was 61.713%. A total of 4 dimensions and 11 factors were obtained. Confirmatory factor analysis showed that, for physical, psychological, social, and pubertal dimensions and total scale, χ2/df values were less than 5, and goodness of fit index (GFI), incremental fit index (IFI) and comparative fit index (CFI) values were greater than 0.9; root mean square error of approximation (RMSEA) value of each dimension was less than 0.08, and RMSEA value of total scale was 0.083; normed fit index (NFI) values of physical and pubertal dimensions were greater than 0.9, and NFI values for the psychological and social dimensions and total scale were 0.883, 0.876, and 0.871, respectively. The coefficient and the test-retest reliability of each dimension and the total scale were 0.648-0.849 and 0.554-0.831, respectively.

Conclusion:

The revised Adolescent Children's Quality of Life Scale has good reliability and validity, suggesting that it can be used for assessing the quality of life of left-behind children in China.
