Psychometric Properties of the Quality of Life Scale for Children and Adolescents with Special Learning Disabilities

The purpose of the present study is to investigate Psychometric properties of 15-item scale of quality of life for children and adolescents with learning problems (LD/QOL15). In a descriptive-correlational study, 195 parents of students with special learning problems were selected through cluster random sampling in Mashhad during the academic year 2018-2019 and responded to LD/QOL15 by Weber et al (2019). Data analysis was performed by EFA, CFA, construct validity and internal consistency analysis using SPSS24 and AMOS20 software. The results showed that the scale had a three-factor structure that explained 62.28% of the variance. Confirmatory factor analysis confirmed this structure as well as the single-factor structure. Internal consistency of the scale with Cronbach's alpha for the dimensions of academic performance, school comprehension, child / family psychological and quality of life were 0.80, 0.84, 0.84, and 0.84, and split-half coefficients were 0.74, 0.84, 0.81 and 0.68, respectively. Therefore, the quality of life of children and adolescents with special learning problems in Mashhad's students has good validity and reliability and can be used as a precise tool in this field.
