Résumé: La détresse de la mort constituerait l'un des problèmes les plus importants de la population âgée et serait encore plus prononcée dans certaines populations âgées spécifiques vulnérables, notamment les personnes vivant en institution. Notre objectif était d'évaluer l'obsession de la mort dans un groupe de personnes âgées non démentes vivant en milieu institutionnel, et d'étudier l'association entre l'obsession de la mort et la religiosité dans cette population. La « Death obsession scale », la « Brief religious coping scale » et la « Arabic religiosity scale » ont été utilisées. Nous avons objectivé des scores de l'obsession de la mort relativement élevés, sans différence selon le genre (score moyen = 33,1 ± 18,1). La régression multiple hiérarchique a trouvé que les variables religieuses (religiosité globale et coping religieux) n'ont pas contribué de manière significative à la variance de l'obsession de la mort. Les personnes âgées vivant dans des maisons de retraite ont des besoins psychosociaux et spirituels spécifiques, que les personnels soignants devraient reconnaître, évaluer et prendre en charge de manière précoce et adéquate. Background: The death distress would be one of the most important problems in the older population and would be more pronounced in some vulnerable older subjects, including those living in nursing homes facilities. We aimed to assess death obsession (DO) in elderly without dementia living in nursing homes, and to examine the association between DO and religiosity. Methods: We carried out a cross-sectional survey involving 42 old subjects living in Manouba nursing home. The "Mini-Mental State Examination", the "Geriatric Depression Scale", the "Activity of Daily Living", the "Cumulative Illness Rating Scale-Geriatric", the "Death Obsession Scale", the "Brief religious coping scale" and the "Arabic Religiosity Scale" were used to assess cognitive functions, depression, level of dependency, comorbidities, death obsession, religious coping and religiosity, respectively. Results: We found relatively high death obsession scores, with no gender differencies (mean scores = 33.1 ± 18.1). The death obsession was significantly and positively associated with comorbidity scores (p = 0.04). No significant correlation was found between death obsession scores and religiosity and religious coping scores in the bivariate analysis. Similarly, multiple hierarchical regression found that religious variables (global religiosity and religious coping) did not significantly contribute to the variance of the death obsession. Conclusion: Older people living in nursing homes have specific psychosocial and spiritual needs, that health care providors should recognize, assess and care for, early and adequately.
