“…The GDS has been found to have adequate psychometric properties. 36 Self-and collateral reports of ADLs were examined with the OARS. 37 Each questionnaire contains 15 items assessing OAs' ability to perform ADLs.…”

Older adults (OAs) with mild cognitive impairment (MCI) are traditionally thought to have preservation of activities of daily living (ADLs). However, recent evidence suggests OAs with MCI may have difficulty completing ADLs and specifically instrumental ADLs (IADLs). The ADLs are frequently evaluated through self- or collateral report questionnaires, while performance-based measures are infrequently utilized, despite the decreased bias and increased accuracy and sensitivity associated with these instruments. This investigation compared ADLs between community-dwelling OAs with (n = 20) and without MCI (n = 30) using a self-report questionnaire (Older American Resources and Services Activities of Daily Living Scale; OARS), a collateral report questionnaire (OARS), and a performance-based measure (the Direct Assessment of Functional Status-Revised). Consistent with our hypothesis, OAs with MCI had decreased ADLs and IADLs on the performance-based measure compared to cognitively intact OAs, while there were no differences in ADLs or IADLs on self-report questionnaires or collateral report questionnaires. Our results suggest OAs with MCI have decreased ability to complete IADLs. However, this investigation suggests these deficits may not be detected by questionnaires and are more likely to be found with performance-based testing.

“…Following admission to the program, the HAM-D is readministered monthly and the GDS is readministered once, at discharge. The GDS assesses the presence or absence of 30 depressive symptoms; a cut-off score of 11 indicates depression and scores above 20 are considered severe (Peach et al, 2001;Yesavage and Brink, 1983). The HAM-D assesses the severity of symptoms; various cut scores ranging from 15 to 18 indicate significant depression and a score of 7 typically signifies remission (Entsuah et al, 2001;Hamilton, 1960;Zimmerman et al, 2002).…”

“…It is a highly reliable and valid instrument that allows early detection of significant mood changes and, therefore, better management of depression-related adverse consequences (Peach, Koob, & Kraus, 2001). The GDS is a time-saving instrument with a simple response format (yes/no), which facilitates its use in different healthcare settings (Jongenelis et al, 2005;Peach et al, 2001).…”

Abstract:The aim of this study was to analyze the screening performance of the European Portuguese version of the 15-item Geriatric Depression Scale (GDS-15) against DSM-5 diagnostic criteria for major depressive episode. The study was multicentre and involved 139 older adults recruited in the context of primary healthcare. Twenty-three participants were diagnosed with clinical depression. Sensitivity and specificity for different cut-off points were determined based on ROC curve analyses. The cut-off point ≥ 4.5 provided optimal sensitivity (95.7%) and specificity (52.6%) rates. After exclusion from the analysis of illiterate participants' data, the optimal cut-off point remained unchanged. The European Portuguese version of GDS-15 is an effective tool for depression screening in older adults. Further studies are needed to verify if there are factors, other than formal education, that may influence the scale's performance.Keywords: Depression; Geriatric Depression Scale; older adults; screening. Exploración de la capacidad de screening de la versión europea portuguesa de la Geriatric Depression Scale de 15 itemsResumen: El objetivo del estudio fue comparar la capacidad de cribado de la versión europea portuguesa de la Geriatric Depression Scale de 15 ítems (GDS-15) respecto a los criterios del DSM-5 en relación con el trastorno depresivo mayor. El estudio fue multicéntrico e incluyó 139 ancianos (23 con diagnóstico de depresión) reclutados en un contexto de atención primaria. La sensibilidad y la especificidad para diferentes puntos de corte fueron obtenidas a través de curvas ROC. La relación de sensibilidad y especificidad reveló ser mejor en el punto de corte ≥ 4.5, resultante en sensibilidad del 95.7% y especificidad del 52.6%. Después de excluirse del análisis de los datos los participantes sin educación formal, el punto de corte óptimo permaneció sin cambios. La versión europea portuguesa de la escala GDS-15 es una herramienta efectiva para el screening de la depresión en ancianos. Se necesitan más estudios para verificar si hay otros factores que puedan influir en el rendimiento de la escala.
