Functional experiences of a LINE-based chatbot and their associations with system use experience among older adults: a cross-sectional study.

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
Background: Population aging has heightened concerns regarding social participation and active aging among older adults. Chatbot-based interventions delivered through familiar messaging platforms have increasingly been adopted to support engagement with community activity programs; however, prior research has often treated chatbots as homogeneous interventions, with limited attention to how specific functional components shape user experiences among older adults. Objective: This study aimed to examine older adults' functional experiences with a LINE-based chatbot designed to support engagement with community activity programs and to investigate how different chatbot functions are associated with overall system use experience. Methods: A cross-sectional survey was conducted among 299 older adults who used a LINE-based chatbot implemented in community-based programs. Functional experiences were assessed across three chatbot modules: information inquiry, photo-based check-in interaction, and task achievement. Composite mean scores were calculated for each functional module and for the overall system use experience scale. Descriptive statistics, Pearson correlation analyses, and multiple linear regression analyses were performed using IBM SPSS Statistics. Results: Participants reported moderate to moderately high levels of functional experience across all chatbot modules. Pearson correlation analyses showed significant positive associations among all functional experience variables. Multiple linear regression analysis indicated that the overall model explained a large proportion of variance in overall system use experience ( Conclusion: The findings suggest that different chatbot functions contribute unequally to older adults' system use experience. Task-oriented and goal-focused functions may play a central role in shaping engagement with chatbot systems, whereas interactive features such as photo-based check-ins may serve a supplementary role. These results underscore the importance of function-specific design when developing chatbot-based interventions intended to support engagement with digital systems designed for community activity programs among older adults.
