025 Chapter 2 Background Research points to the effectiveness of educational interventions to raise awareness of ageist attitudes and behaviours and to challenge them.64 For example, a study in the United States found that a videobased educational intervention was effective in reducing ageism among aged care workers.65 This study found long-term, positive changes in participants’ attitudes, thinking, behaviour and language, following a single, video-based education session. Interventions that aim to foster positive interactions between people of different generations have also been shown to be effective in reducing ageism against older adults.66 However, intergenerational contact alone is not sufficient; the quality of contact plays an important role.67 For example, ‘home share’ programs, which match older adults who live alone with younger people in need of accommodation, provide opportunities for sustained intergenerational contact and may have the added benefit of reducing ageist stereotypes and attitudes among those involved. A third type of ageism intervention combines education and intergenerational contact. A systematic review and meta-analysis of ageism interventions commissioned by the WHO for its 2021 Global Report on Ageism, found that combined interventions, along with educational and intergenerational contact interventions, resulted in improvements in participants’ attitudes towards older adults and knowledge about ageing.68 The review also identified notable gaps in the current ageism intervention literature. First, the majority of interventions that have been formally evaluated are from the United States, and while there is some translatability, it is important for interventions to be tested in other contexts. Secondly, most evaluations of ageism interventions have taken place in formal educational settings (ie, schools, universities) and targeted students, with only a small number delivered in non-formal learning settings (eg, workplaces or community centres).69 Given these gaps, the present research contributes to a greater understanding of the effectiveness of an educational intervention for workers in aged care and community settings in the Australian context.
