The Arabic Hospital Anxiety and Depression Scale: validation in a sample of Lebanese patients with cancer

Abstract

BackgroundDepression and anxiety are common comorbid psychological disorders among patients with cancer. Despite the wide use of the Arabic Hospital and Anxiety Scale (HADS) in oncological settings, it has not been yet validated among Lebanese patients with cancer. We aimed to assess the reliability and validity of the HADS in a sample of Lebanese patients with cancer. One-hundred one Lebanese patients diagnosed with cancer presenting to the Ambulatory Care Center in the Hematology Oncology Department at the American University of Beirut Medial Center filled the Arabic version of the HADS. The Generalized Anxiety Disorder 7-Item Scale (GAD-7) and the Patient Health Questionnaire 9-Item Scale (PHQ-9) were used to assess its concurrent validity in capturing anxiety and depression, respectively.ResultsReliability analysis using Cronbach’s alpha (α) coefficient revealed good internal consistency for the Arabic HADS (α = 0.89) and both subscales (α = 0.86 for depression and α = 0.78 for anxiety). Correlations between HADS with both GAD-7 and PHQ-9 were statistically significant and strong for both depression (r = 0.795; p < 0.0001) and anxiety (r = 0.727; p < 0.0001). Confirmatory factor analysis revealed that the observed data fits the two-factor model of depression and anxiety (Kaiser–Meyer–Olkin = 0.86; Tucker Lewis Index = 0.879; root-mean-square error of approximation = 0.08). Depression and anxiety rates were approximately 52% and 25%, respectively.ConclusionWe conclude that the Arabic version of the HADS is a credible and valid tool for clinical assessment of psychological distress (anxious and depressive states) among Lebanese patients with cancer.
