A 12-week application-based group conversation intervention on cognitive health and psychosocial well-being among older adults during the COVID-19 pandemic: a randomized controlled trial.
Trial report in BMC geriatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFollowing empirical evidence suggesting a strong connection between social activities and longevity/well-being, this topic has now entered an intervention phase, which evaluates the effectiveness of social activity interventions and accumulates practical knowledge. Among these interventions, conversation-as a core component of social activity-has emerged as a promising target for cognitive, social, and psychological health.
objectiveThis study examined the effects of "Photo-Integrated Conversation Moderated by Application" (PICMOA), an application-based remote conversational intervention, on the cognitive function and psychological and social well-being, as reflected by selected indicators, among community-dwelling older adults with subjective cognitive concerns in Japan.
methodsThe PICMOA trial is a randomized controlled trial introducing an open-label, two parallel group trial design with a 1:1 allocation. In this trial, the effects of the PICMOA intervention, a weekly application-based group conversation, were compared with weekly health education videos. The participants included community dwellers aged 65 years and older with subjective cognitive concerns. The main outcomes included cognitive function assessed through the Telephone Interview for Cognitive Status in Japanese, verbal fluency test, and Digit Span Forward and Backward tests. The secondary outcomes included indicators related to psychological and social well-being, assessed using the Multidimensional Scale of Perceived Social Support, the UCLA Loneliness Scale-10 item version, the 5-item World Health Organization Well-Being Index, and the Health Utilities Index Mark 3.
resultsIn total, 81 participants were randomized and divided into two groups (intervention: n = 41; control: n = 40). A total of 75 participants who completed the intervention and evaluations were analyzed (intervention: n = 35; control: n = 40). There were no significant improvements associated with cognitive function and psychological metrics in the intervention group compared with the control group during the 12-week intervention. However, the ancillary analysis showed significant decline in the categorical fluency performance for those who were unfamiliar with smartphones at baseline (b = -5.47, SE = 2.04, P = 0.009), suggesting a moderating effect of participants' familiarity with smartphones at baseline.
conclusionsThis trial showed no significant improvements in cognitive and psychological outcomes after the PICMOA intervention. However, the findings raise important considerations regarding participants' familiarity with digital devices and intervention setting. Further research is needed to accumulate evidence on the duration and intensity of intervention and individual support for improving digital literacy.
