Rasch validation of the Arabic version of the beach center family quality of life scale (BCFQOL-AR)

Abstract

AimThis study aimed to examine the dimensionality of the BCFQOL-AR using Rasch analysis.MethodThe sample consisted of 320 families having a member with intellectual or developmental disabilities. Rasch analysis was used to validate the dimensionality of the scale. The participants were from Riyadh, Saudi Arabia.ResultsThe BCFQOL-AR 25-item scale was multidimensional. Rasch analyses support the unidimensionality of the five subscales. There were no indicators of differential item function for any of the items, regardless of sex or age.ConclusionThe BCFQOL-AR is a multidimensional scale that measures families with members who are satisfied with their quality of life. Therefore, obtaining a total score at the subscale level is supported and showed that each of the five subscales of the BCFQOL can be used alone. This study partially supports the practices used with other versions of the scale, by providing the statistical base, where means were used at the subscale level in different countries.

Variations in Perceptions of Well-Being within Families of Youths with Intellectual Disabilities in Saudi Arabia

“…By concentrating on these three domains, our study aimed to gain a deeper understanding of the nuanced ways in which a youth’s intellectual disability affects the family’s quality of life. It is important to elucidate that our selection was informed by the foundational work of Alnahdi [ 30 ], which emphasized the multidimensionality of the Beach Center Family Quality of Life (BCFQOL) scale. Alnahdi’s study provided statistical evidence, via Rasch analysis, underscoring the unidimensional nature of each of the subscales, thereby validating the independent use of each subscale to assess distinct dimensions of family quality of life.…”
