Abstract:
Background: Parents of children with disabilities often experience reduced quality of life (QoL), yet validated Arabic instruments remain limited. This study aimed to translate and validate the Arabic version of the Multicultural Quality of Life Index (MQLI-Ar). Methods: A cross-sectional study was conducted among 132 parents and caregivers in Saudi Arabia. The MQLI was translated using forward-backward translation and culturally adapted. Reliability and validity were assessed using Cronbach's alpha, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). Results: The MQLI-Ar demonstrated high internal consistency (Cronbach's alpha = 0.948). EFA supported a unidimensional structure explaining 68.3% of the variance. CFA indicated acceptable model fit (CFI = 0.934, TLI = 0.915, SRMR = 0.0397), although RMSEA was elevated. Factor loadings ranged from 0.642 to 0.919, confirming strong item-factor relationships. Conclusions: The MQLI-Ar is a reliable and valid tool for assessing QoL among Arabic-speaking caregivers of children with disabilities, supporting its use in research and clinical practice.

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
