Trauma-informed care (TIC) psychoeducational group-based interventions for foster carers and adoptive parents are growing, but evidence about their effects have not been integrated. A narrative review was undertaken of studies that evaluated the effects of these interventions. It found that they appear to increase carers’ capacity to provide children with TIC and reduce child trauma-related difficulties. Three core components – psychoeducation, reflective engagement and skills building – were identified as helping to explain how the interventions work. However, the evidence is weak due to the mixed findings, diverse research designs, varied measures and methodological deficiencies, so results should be interpreted with caution. This highlights the urgent need for more rigorous research. Implications for practice, policy and research are discussed.

针对寄养者和养父母的创伤知情护理 (TIC) 基于心理教育团体的干预措施正在增加，但尚未整合有关其影响的证据。对评估这些干预措施效果的研究进行了叙述性审查。它发现它们似乎提高了照顾者为儿童提供 TIC 的能力，并减少了与儿童创伤相关的困难。三个核心组成部分——心理教育、反思性参与和技能培养——被确定为有助于解释干预措施的工作原理。然而，由于结果参差不齐、研究设计多样、措施多样和方法论缺陷，证据薄弱，因此应谨慎解释结果。这凸显了进行更严格研究的迫切需要。讨论了对实践、政策和研究的影响。
