Photovoice (PV) was conceptualized in the early 1990s to engage community members in capturing/communicating their lived experience narratives through photography. However, no meta-analyses in health research have assessed whether PV achieves its purported effects.
We carried forward any relevant references from a previous review identifying PV studies before 2008 and searched MEDLINE, Embase, PsycINFO and Cochrane Central Register of Controlled Trials from 2008 up until October 2019. We included both published and grey literature, in any population or context. We assessed quality with the Effective Public Health Practice Project's (EPHPP) tool and pooled studies using the standardized mean difference (SMD) and 95% confidence intervals (CIs).
Twenty-eight studies were included, showing significant post-treatment effects only for health knowledge (SMD, 95% CIs = 0.41, 0.09 to 0.73, n = 16) and community functions (SMD, 95% CIs = 0.22, 0.03 to 0.40, n = 4). Strong heterogeneity was indicated for health knowledge, potentially explained by a larger effect in ethnic minority populations. There was insufficient follow-up data for health knowledge, while in follow-up for community functions the post-treatment effect was lost.
PV's post-treatment effect on health knowledge did not translate into positive health behaviours or physical and mental health outcomes, longer-term community functions, or health service outcomes.
摄影法（PV）于 20 世纪 90 年代初提出，旨在通过摄影让社区成员捕捉和交流他们的生活经历叙述。然而，在健康研究中，没有荟萃分析评估 PV 是否达到其预期效果。
我们从前瞻性综述中检索了 2008 年之前的 PV 研究相关参考文献，并在 2008 年至 2019 年 10 月期间检索了 MEDLINE、Embase、PsycINFO 和 Cochrane 对照试验中心注册库。我们纳入了所有人群或背景下的已发表和灰色文献。我们使用有效公共卫生实践项目（EPHPP）工具评估质量，并使用标准化均数差（SMD）和 95%置信区间（CI）对研究进行汇总。
共纳入 28 项研究，仅显示出健康知识（SMD，95%CI=0.41，0.09 至 0.73，n=16）和社区功能（SMD，95%CI=0.22，0.03 至 0.40，n=4）在治疗后有显著效果。健康知识存在较大的异质性，可能是由于少数民族群体的影响更大。健康知识的随访数据不足，而在社区功能的随访中，治疗后的效果消失。
PV 对健康知识的治疗后效果并未转化为积极的健康行为或身心健康结果、长期的社区功能或卫生服务结果。
