Abstract Introduction Symptoms of depression and anxiety, with and without dementia, are common in older care home residents. It is postulated that that watching films can help residents to share emotions, enhance social connectedness and engage in reminiscence. As such, films can ameliorate depression and promote well-being. This scoping review summarises the evidence for the therapeutic benefits of film-based interventions in care homes. Methods Electronic databases MEDLINE, Embase, EMCare and CINAHL were searched for quantitative and qualitative studies in English including adults aged 65 years and older in years 2005–2023. The search terms were: older adults, dementia, depression, carers, caregivers, care homes, and film. Results Five studies met our criteria: Campbell-Sills, 2006, USA; Kim, 2014, Korea; Davison et al., 2016, Australia; Bjornskov et al., 2018, Denmark; and Breckenridge et al., 2020, UK. All subjects were care home residents except for Bjornskov et al., who included 63 institutional caregivers. The number of study participants ranged from 11 to 120. There was a female predominance throughout the studies, and all residents had dementia of varying severity. Study designs included: direct comparison of participants with mood/anxiety disorder versus controls (Campbell-Sills); non-equivalent control group pretest/posttest (Kim); randomised single-blind crossover (Davison); qualitative focus-group caregiver interviews (Bjornskov); and cross-sectional observation (Breckenridge). Observation/follow up periods ranged from 6–10 weeks. Findings were as follows Campbell-Sills: residents with mood/anxiety disorders were identified by suppressing negative emotions induced by films; Kim: group reminiscence therapy using cinema increased ego integrity and reduced depression severity; Davison et al: using a personal computer platform that included films resulted in reductions in anxiety, depression and agitation; Bjornskov et al.: caregivers reported that films can evoke reminiscence; Breckenridge et al.: small-group film viewing enhanced social connectivity. Conclusions Film screenings for ageing care home residents have the potential for improving mood and encouraging social connections.
