Evaluation of apathy among institutionalized older persons: Its mediating role between cognitive functioning and lack of awareness

Abstract

AbstractObjectivesThe main objective of this study was to determine the directions of the relationships between apathy, cognitive deficits and lack of awareness.MethodsOne hundred and twenty‐one older persons living in nursing homes, aged between 65 and 99 years old, participated in the study. Cognitive functioning, autonomy, depressive and anxious symptoms, general self‐efficacy, self‐esteem and apathy were evaluated through tests and questionnaires. Lack of awareness was calculated using the patient‐caregiver discrepancy method. The sample was divided into two groups (n1 = 60, n2 = 61) depending on cognitive functioning level (Dementia Rating Scale < median score: 120). We first explored the characteristics of each group. Then, we compared the mode of evaluation of apathy. Finally, we investigated the direction of relationships by applying mediation analyses.ResultsOlder persons in the low cognitive functioning group were less autonomous, had a lower cognitive functioning level, higher caregiver‐rated apathy and higher lack of awareness than the high cognitive functioning group (ps < 0.05). Evaluation differences were found only in the low cognition group. Caregiver‐rated apathy totally mediated the relationship between cognitive functioning (predictor) and lack of awareness (dependent variable) for the whole sample (90%) and for the low cognitive functioning group (100%).ConclusionsCognitive deficits should be taken into account when evaluating apathy. Interventions should combine cognition training and emotion intervention to reduce lack of awareness. Future research should develop a therapy dedicated to apathy among older persons without pathologies.
