This paper describes a randomized controlled trial on the Online Life Story Book (OLSB), a digital reminiscence intervention for people with (very) mild dementia living at home. The aim of the study was to investigate the effectiveness of the OLSB on (i) neuropsychiatric symptoms (NPS) in persons with dementia and (ii) the distress and quality of life (QOL) of primary informal caregivers. A randomized controlled trial with individual randomization to one of two conditions was conducted: 1) intervention "Online Life Story Book"; 2) wait list control condition. In the intervention OLSB, a trained volunteer guided the participants through the process of creating an OLSB in approximately 5 meetings within a period of 8-10 weeks. Participants in the control condition received care as usual while they waited for 6 months before starting. Outcomes on NPS and distress and QOL of the informal caregiver were assessed at baseline (baseline, T0), 3 months (T1) and 6 months (T2) post baseline. Of the 42 persons with dementia, 23 were female and 19 were male. They had a mean age of 80 years, ranging from 49 to 95. The total drop-out rate was 14.3 percent. Small but insignificant effects on NPS, caregiver distress and QOL of caregivers were found with the exception of self-rated caregiver distress that reduced significantly during the intervention. One reason to explain the results might be that the included participants were in relatively good health. Practical challenges during the intervention could have affected the results as well. It might also be that the intervention caused effects on other outcomes than NPS and caregiver distress. In future research, it is important to study the effects in persons with more complaints and higher distress and to be careful in the selection of outcome variables in relation to the reminiscence functions served by the intervention.

在线生活故事书：一项关于数字回忆干预对（非常）轻度痴呆症患者及其非正式照顾者的影响的随机对照试验。

本文描述了一项关于在线生活故事书 (OLSB) 的随机对照试验，这是一种针对居家（非常）轻度痴呆症患者的数字回忆干预。该研究的目的是调查 OLSB 对 (i) 痴呆症患者的神经精神症状 (NPS) 和 (ii) 主要非正式照顾者的痛苦和生活质量 (QOL) 的有效性。进行了一项随机对照试验，将个体随机分配到以下两种情况之一：1）干预“在线生活故事书”；2) 等待列表控制条件。在干预 OLSB 中，一名训练有素的志愿者在 8-10 周内通过大约 5 次会议指导参与者完成创建 OLSB 的过程。对照条件下的参与者在开始前等待 6 个月时照常接受护理。在基线（基线，T0）、基线后 3 个月 (T1) 和 6 个月 (T2) 评估了 NPS 和非正式照顾者的痛苦和 QOL 的结果。在 42 名痴呆症患者中，23 名女性，19 名男性。他们的平均年龄为 80 岁，从 49 岁到 95 岁不等。总辍学率为 14.3%。发现对 NPS、照顾者痛苦和照顾者 QOL 的影响很小但不显着，但自我评估的照顾者痛苦在干预期间显着减少。解释结果的一个原因可能是所包括的参与者身体状况相对较好。干预期间的实际挑战也可能影响结果。也可能是干预对 NPS 和照顾者痛苦以外的其他结果产生了影响。在未来的研究中，
