To examine the efficacy of the Dementia Stigma Reduction (DESeRvE) programme, aimed at reducing the general public dementia-related stigma utilising 'education' and 'contact' approaches.
A total of 1024 Australians aged between 40 and 87 years (M = 60.8, = 10.1) participated in a factorial randomised controlled trial. This trial examined four conditions: online education programme (ED), contact through simulated contact with people with dementia and carers (CT), education and contact (ED+CT) and active control. Cognitive, emotional and behavioural aspects of dementia-related stigma were measured with a modified Attribution Questionnaire, and dementia knowledge was measured with the Dementia Knowledge Assessment Scale at the baseline, immediately and 12 weeks after the completion of the intervention.
All four groups improved (reduction in scores) significantly from baseline to week 12 in dementia-related stigma, and the effects were stronger for those with higher baseline stigma scores. Intervention groups also improved significantly from baseline in dementia knowledge. Especially, the ED (β = .85, SE = .07; < .001) and ED+CT (β = .78, SE = .08; < .001) groups at immediate follow-up and CT (β = .21, SE = .09; < .05) and ED+CT (β = .32, SE = .09; < .001) at 12-week follow-up showed significant effects.
Findings suggest that DESeRvE can be a valuable tool to enhance public's dementia knowledge and reduce dementia-related stigma, especially for those with higher levels of stigma. Reduction in stigma, however, may take a longer time to achieve, whereas improvement in dementia knowledge is instant.
本研究旨在采用“教育”和“接触”方法，检验旨在减少公众对痴呆症相关污名的 Dementia Stigma Reduction（DESeRvE）计划的疗效。
共有 1024 名年龄在 40 至 87 岁之间的澳大利亚人（M=60.8，=10.1）参与了一项完全随机对照试验。该试验检验了四种条件：在线教育计划（ED）、通过与痴呆症患者和照护者的模拟接触进行接触（CT）、教育和接触（ED+CT）以及积极对照。使用改良归因问卷测量与痴呆症相关的污名的认知、情感和行为方面，使用痴呆症知识评估量表测量痴呆症知识，在基线、干预完成后立即和 12 周后进行测量。
所有四组在基线到 12 周时，与痴呆症相关的污名都显著改善（得分降低），且基线污名得分较高的组改善效果更强。干预组在痴呆症知识方面也有显著改善。特别是 ED（β=0.85，SE=0.07；<0.001）和 ED+CT（β=0.78，SE=0.08；<0.001）组在即时随访时，CT（β=0.21，SE=0.09；<0.05）和 ED+CT（β=0.32，SE=0.09；<0.001）组在 12 周随访时显示出显著效果。
研究结果表明，DESeRvE 可以成为增强公众对痴呆症知识和减少与痴呆症相关污名的有效工具，特别是对于那些污名程度较高的人群。然而，污名的减少可能需要更长的时间才能实现，而痴呆症知识的提高则是即时的。
