Abstract

BACKGROUND

Social activity is a key component in the prevention of cognitive decline. However, face-to-face social intervention has limited accessibility. To address this issue, we developed the "Photo-Integrated Conversation Moderated by Application" (PICMOA), a home-based group conversation intervention using smartphones. This paper introduces the PICMOA intervention and the protocol of the ongoing randomized controlled trial (RCT), which aims to evaluate the effects of PICMOA on the cognitive functioning and psychological well-being of Japanese community dwelling older adults at the risk of cognitive function decline.

METHODS

This study uses an RCT design in two parallel group trials with 1:1 allocation. The participants are community dwelling older adults aged 65 years and above, living in an urban city in Japan, with subjective cognitive concerns. In total, 81 participants were allocated to the intervention or control groups. The intervention group receives 30 min of weekly PICMOA sessions at their home for 12 weeks. The PICMOA intervention consists of (1) a photo preparation period before the session and (2) a structured group conversation session talking about the photos that participants took according to a specific theme. The control group receives 30 min of weekly health education videos on a tablet device. The primary outcome is cognitive functioning at pre- and post-phases of the 12-week intervention measured using the Telephone Interview for Cognitive Status in Japanese, semantic and phonemic fluency tests, and the Digit Span Forward and Backward tests. The secondary outcomes are psychological and social aspects including mental status, well-being, loneliness, and social support.

DISCUSSION

Interest is growing in internet-based activities for preventing social isolation. However, the effect of remote conversation interventions on cognitive functioning remains unclear. This study addresses this issue and provides a new avenue of social participation for older adults.

摘要

背景

社交活动是预防认知衰退的关键组成部分。然而，面对面的社交干预可及性有限。为解决这一问题，我们开发了“应用程序介导的照片整合对话”（PICMOA），这是一种使用智能手机的居家小组对话干预方式。本文介绍了PICMOA干预以及正在进行的随机对照试验（RCT）方案，该试验旨在评估PICMOA对有认知功能衰退风险的日本社区老年人认知功能和心理健康的影响。

方法

本研究采用RCT设计，在两个平行组试验中按1:1分配。参与者为居住在日本城市、年龄在65岁及以上、有主观认知问题的社区老年人。共有81名参与者被分配到干预组或对照组。干预组每周在家接受30分钟的PICMOA课程，为期12周。PICMOA干预包括（1）课程前的照片准备期和（2）根据特定主题谈论参与者所拍照片的结构化小组对话期。对照组每周在平板电脑设备上观看30分钟的健康教育视频。主要结局是在12周干预的前后阶段使用日语认知状态电话访谈、语义和语音流畅性测试以及数字广度顺背和倒背测试来测量的认知功能。次要结局是心理和社会方面，包括精神状态、幸福感、孤独感和社会支持。
