尽管低收入和中等收入国家（LMIC）的痴呆症负担很高，但在这些环境中，只有少数痴呆症患者（PwD）的心理社会干预临床试验。至关重要的是，这些试验使用适当的结果措施，在方法上是强大的和文化上适当的评估干预措施的有效性。我们进行了系统的审查，以检查在这些研究中采用的措施，在中低收入国家的证据基础和心理测量学特性。对2008年至2020年4月期间LMIC中PwD心理社会干预的随机对照试验（RCT）的已发表文献进行了系统检索。在每个合格的研究中采用的措施进行了识别，并通过集中搜索，我们进一步探讨了证据基础和心理测量学特性采用Terwee标准。数据提取和质量评价由两名独立的评审员进行。该综述从17个符合资格标准的RCTS中确定了41项措施，并检查了认知（n = 16），行为和心理症状（n = 11）和生活质量（n = 8）领域的有效性。在这41个，我们能够访问相关的文献只有18个，他们受到心理测量分析。这18种工具的心理测量特性充其量是适度的，Terwee评分从3（低）到15（中等）不等。大多数研究来自中国（n = 5）和巴西（n = 6）。LMIC PwD非药物干预RCT中常规采用的措施的证据基础有限。这些工具的适应和验证的质量是可变的，研究在很大程度上是没有信息的心理测量特性和文化适当的研究设置。迫切需要在LMIC环境中开发科学可靠的工具，可以自信地用于测量PwD心理社会干预试验的结果。
Despite high burden of dementia in low‐and middle‐income countries (LMICs), only a small number of clinical trials of psychosocial interventions for persons with dementia (PwD) have been conducted in these settings. It is essential that such trials use appropriate outcome measures that are methodologically robust and culturally appropriate to evaluate the effectiveness of interventions. We carried out a systematic review to examine the evidence base and psychometric properties of measures employed in these studies in LMICs. A systematic search of published literature on randomised controlled trials (RCT) of psychosocial interventions for PwD in LMICs between 2008 and April 2020 was carried out. Measures employed in each of the eligible studies were identified and through a focused search, we further explored the evidence base and psychometric properties employing Terwee criteria. Data extraction and quality appraisal were conducted by two independent reviewers. The review identified 41 measures from 17 RCTS which fulfilled eligibility criteria and they examined effectiveness across the domains of cognition (n = 16), behaviour and psychological symptoms (n = 11) and quality of life (n = 8). Of these 41, we were able to access relevant literature only for 18 and they were subject to psychometric analysis. Psychometric properties of these 18 instruments were at best modest, with Terwee scores ranging from 3 (low) to 15 (moderate). A majority of the studies were from China (n = 5) and Brazil (n = 6). The evidence base for the routinely employed measures in RCTs of non‐pharmacological interventions for PwD in LMICs is limited. The quality of adaptation and validation of these instruments is variable and studies are largely uninformative about their psychometric properties and cultural appropriateness to the study setting. There is an urgent need to develop scientifically robust instruments in LMIC settings that can be confidently employed to measure outcomes in trials of psychosocial interventions for PwD.
