RESUMEN
Salutogenesis is a health-promoting orientation and sense of coherence (SOC) is a vital coping factor associated with quality of life (QOL) and self-efficacy. Although salutogenic-based interventions showed potential in improving health outcomes, the application of salutogenic concepts and effectiveness on SOC, QOL and self-efficacy among community-dwelling older adults remained unclear. This review aimed to consolidate evidence on salutogenic approaches and evaluate the effectiveness of salutogenic-based interventions on SOC, QOL and self-efficacy in community-dwelling older adults. Databases systematically searched include PubMed, CINAHL, Embase, Cochrane Central Register of Controlled Trials, Scopus, Medline, PsycINFO and ProQuest Dissertations & Theses Global electronic databases. Two reviewers screened study eligibility, assessed risk of bias and extracted data of included studies independently. Meta-analyses on SOC and QOL were performed using RevMan. Where meta-analysis was not possible, narrative synthesis was employed. Eight studies involving 1201 older adults were included in this review. Subgroup analysis on SOC showed significant effects favouring salutogenic-based interventions using the empowering self-management model or strengths/resource-based approaches. However, results were mixed for the reflection-based approach. No significant effect favouring salutogenic-based interventions on QOL outcomes were found. High heterogeneity was observed for the outcome on self-efficacy. Two SOC strengthening processes, empowerment and reflection, were found to potentially underlie salutogenic-based intervention mechanisms. Effectiveness of salutogenic-based interventions on SOC, QOL and self-efficacy among community-dwelling older adults remained inconclusive due to high heterogeneity. Future salutogenic-based interventions should employ longitudinal designs and standardization on intervention delivery, utilizing a dual pathway via empowerment and reflection.
