Interventions to improve attitudes toward older people in undergraduate health and social sciences students. A systematic review and meta-analysis

Abstract

Objective: To determine which interventions are the most effective in improving attitudes toward older persons in undergraduate health and social sciences students.

Design: Systematic review and meta-analysis.

Data sources: A literature search was made in PubMed, EBSCO and SCOPUS and additional records were identified by manual searching. The selection criteria were studies that evaluated an intervention designed to improve positive attitudes; studies in undergraduate health and social sciences students; and studies using direct instruments to measure attitudes.

Review methods: Two independent reviewers extracted study-level data from records using a common data collection spreadsheet. Two reviewers also assessed study quality by using the Cochrane Risk of Bias Tool. The primary outcome was the effect of an intervention upon attitudes toward older people, while the secondary outcome was the effect upon knowledge about aging and older people in those studies that had previously assessed subject attitude. The meta-analysis was carried out based on mixed statistical models.

Results: The search identified 53 eligible studies published during 1982-2020, comprising 35 pre-post studies and 18 randomized clinical trials, of which 14 were included in the meta-analysis. A strongly significant effect upon attitudes was observed for empathy-based interventions (differences of standardized mean differences (d_SMD) = 1.26; 95%CI: 0.04-2.48; p = 0.04), knowledge + empathy-based interventions (d_SMD = 0.22; 95%CI: 0.05-0.39; p = 0.01), and knowledge + clinical skills-based interventions (d_SMD = 0.22; 95%CI: 0.01-0.43; p = 0.04). The overall effect was d_SMD = 0.50; 95%CI: 0.01-0.43; p = 0.004. In addition, a positive effect in terms of increased knowledge about the older was observed after knowledge + empathy-based and knowledge + clinical skills-based interventions (d_SMD = 0.24; 95%CI: 0.07-0.40; p = 0.005).

Conclusions: Interventions to improve attitudes in health and social sciences students are effective, with those based on empathy having the greatest impact. Improving attitudes among future professionals could improve the management and quality of care of older people. More rigorous and better designed studies are recommended to determine the effect of the interventions. Registered on PROSPERO ID: CRD42021220677.
