The study provides valuable insights into the validation of the Spiritual Distress and Resources Questionnaire (SDRQ) in patients with affective disorders. However, a few aspects could benefit from further clarification. First, while the study establishes construct validity through correlations with established measures, could the authors elaborate on whether any confirmatory factor analysis (CFA) was conducted? Moreover, the study highlights the strong correlation between spiritual distress and psychological distress (HADS-D), but it would be helpful to discuss potential confounding variables. For instance, were factors like social support or past religious experiences considered, as they might influence both spiritual distress and mental health outcomes?
