Research Article: Optimal GRID-HAM-D7 cut-off scores for defining remission in older Thai adults with depression
Abstract:
The 7-item Hamilton Depression Rating Scale (HAM-D7) is commonly used to assess depression severity and remission; however, its standard cut-off scores may not be optimal for elderly populations. This study aimed to establish GRID-HAM-D7 remission thresholds among elderly Thai patients diagnosed with depressive disorders, including both any depressive disorder and major depressive disorder (MDD).
A total of 803 elderly participants were recruited from four tertiary care hospitals across Thailand as part of a larger psychiatric study. Diagnoses were determined using the Mini International Neuropsychiatric Interview, and depression severity was assessed via the GRID-HAM-D7. Statistical analyses, including sensitivity, specificity, predictive values, and Receiver Operating Characteristic curves, were performed to determine optimal remission cut-off scores.
For any depressive disorder, a GRID-HAM-D7 score of ? 4 yielded sensitivities of 88.86% and specificity of 77.66%. In major depressive disorder, the optimal threshold was ? 6, resulting in 91.68% sensitivity and 79.73% specificity. Both values surpassed the diagnostic accuracy of conventional lower thresholds. These results suggest that higher GRID-HAM-D7 remission cut-offs better reflect depressive symptomatology in older adults.
The study underscores the necessity of tailoring standardized assessment tools for specific populations to enhance clinical management and decision-making in geriatric psychiatry.
Introduction:
Major depressive disorder (MDD) is a profound global health concern, especially among older adults. Depression in this population is common, frequently under-recognized, and often undertreated. With a prevalence rate of 31.74% among the global elderly population ( 1 ), the need for regular screening and effective interventions is clear. This high rate highlights the importance of proactive strategies for detection and management in older adults. Recognizing these challenges, clinicians require reliable and…
