Abstract

Background: Societal stigma towards people with addiction fuels exclusion, undermines social support, and inhibits help-seeking. We evaluated a wordless, short animated storytelling (SAS) social contact video in three countries.

Methods: We conducted a three-arm, online randomised controlled trial in the UK, USA, and South Africa. Adults aged 18-49 years were recruited via Prolific Academic between July 10th and July 24th, 2025, and randomly assigned (1:1:1) to a 2 min 40 s SAS video with soundtrack, the same video without soundtrack, or an informational control delivered within the online survey platform. The primary outcome was stigma towards people with addiction, measured using the 18-item Attribution Questionnaire (AQ-18) immediately post-exposure (T1) and two weeks later (T2). Secondary outcomes were optimism (Brief García Interactive Optimism Scale), hopefulness and attitudes of warmth towards people with addiction. Analyses included all participants who completed the relevant assessment and met attention-check criteria. Effects were estimated as ratios of means with robust standard errors and country fixed effects. The trial was registered with ClinicalTrials.gov (NCT06705205; Nov 22, 2024).

Findings: Between July 10th and July 24th, 2025, 13,500 participants were recruited; 13,397 (99%) completed T1 and 92% completed T2. Compared with control, mean stigma scores were 9% lower at T1 in the soundtrack group (ratio of means 0·91; 95% CI 0·90-0·93) and 6% lower in the no-soundtrack group (0·94; 0·93-0·95). At T2, stigma remained 4% lower with soundtrack (0·96; 0·95-0·97) and 2% lower without soundtrack (0·98; 0·97-0·99). Secondary outcomes improved at T1 in both intervention groups; at T2, warmth remained higher with attenuation.

Interpretation: Single exposure to a wordless SAS social contact intervention reduced addiction stigma across three countries, with greater and more durable effects when accompanied by soundtrack. Our findings support integrating SAS social contact interventions into population-level addiction stigma reduction campaigns.

在英国、美国和南非进行的一项随机对照试验中,简短的动画故事社交视频减少了成瘾的耻辱感。
背景:对成瘾者的社会污名加剧了排斥,破坏了社会支持,并抑制了寻求帮助。我们在三个国家评估了一个无声的简短动画故事(SAS)社交视频。方法:我们在英国、美国和南非进行了一项三组在线随机对照试验。在2025年7月10日至7月24日期间,通过多产学术网站招募了18-49岁的成年人,并随机分配(1:1:1)观看2分钟40秒的SAS视频,其中有配乐,同样的视频没有配乐,或者在在线调查平台上提供信息控制。主要结果是对成瘾者的耻辱感,使用18项归因问卷(AQ-18)在接触后立即(T1)和两周后(T2)进行测量。次要结果为乐观(简要García互动乐观量表)、对成瘾者的希望和温暖态度。分析包括所有完成相关评估并符合注意检查标准的参与者。效应用具有稳健标准误差的均值和国家固定效应的比值来估计。该试验已在ClinicalTrials.gov注册(NCT06705205; 2024年11月22日)。研究结果:在2025年7月10日至7月24日期间,招募了13500名参与者;13397例(99%)完成T1, 92%完成T2。与对照组相比,配乐组在T1时的平均病耻感得分低9%(均值比值为0.91;95% CI为0.90 - 0.93),无配乐组的平均病耻感得分低6%(0.94;0.93 - 0.95)。T2时,有配乐的病耻感降低4%(0.96;0.95 ~ 0.97),无配乐的病耻感降低2%(0.98;0.97 ~ 0.99)。两个干预组的次要结局在T1时均有所改善;在T2,随着衰减,热量保持较高。解释:在三个国家中,单次接触无声的SAS社会接触干预减少了成瘾的耻辱感,当伴有配乐时,效果更大,更持久。我们的研究结果支持将SAS社会接触干预纳入人口层面的成瘾污名减少运动。资助:德国海德堡大学医院海德堡全球健康研究所。没有指定具体的资助编号。
