This systematic review examines widely used mental health measurement scales, including the Perceived Stress Scale, General Health Questionnaire, Depression Anxiety Stress Scale, Mental Health Inventory, Ryff's Psychological Well-Being Scale, and Warwick-Edinburgh Mental Well-being Scale. It highlights that mental health assessment requires both negative dimensions (stress, anxiety, depression) and positive dimensions (well-being, resilience, life satisfaction). The review finds that no single scale fully captures mental health's complexity, recommending multi-scale approaches. It identifies a research gap in integrating spiritual-based interventions such as Rajyoga meditation with standardized psychometric assessments. The authors conclude that combining well-being and distress measures provides a more comprehensive understanding of mental health outcomes in intervention studies.
