Cross-Cultural Adaptation and Validation of the Arabic Version of the Rating Anxiety in Dementia Scale.
Objectives: This study aims to cross-culturally adapt the Rating Anxiety in Dementia (RAID) scale into Arabic language, evaluate its psychometric properties in a sample of Lebanese patients with dementia and determine the optimal cutoff for the identification of anxiety. Methods: A cross-sectional study was carried out with a sample of 136 patients with dementia aged 55 years and above. RAID-A was administered to a formal caregiver of the patient as well as a battery of psychological tools namely Hamilton anxiety scale (HAM-A) and Neuropsychiatric Inventory anxiety subscale (NPI-A). ⋯ Results from the receiver operating curve analysis identified a score of 11 as the optimal cutoff for the diagnosis of GAD with a sensitivity of 91% and a specificity of 82%. Conclusions: The Arabic version of the RAID scale exhibits good psychometric properties. Clinical Implications: RAID is a valid tool to measure anxiety in Arabic elder patients suffering from dementia.
