Figure 1
The conceptual model consists of five rectangular boxes arranged from left to right. The rectangular box on the left is labeled “I V Self-learning Service for Older Adults (Study 1, 2, 3)”. A horizontal solid arrow labeled “H 1” above and “H 2” below it from this box points to a rectangular box at the center labeled “Mediator”. The “Mediator” box includes two bulleted points: “Personal Growth (Study 1, 2)” and “Social Connectedness (Study 3)”. From the “Mediator” box, a horizontal solid arrow points right to a rectangular box on the far right labeled “D V”. The “D V” box contains four bulleted points: “Service Usage Intention (Study 1, 2, 3)”, “Service Referral Intention (Study 1, 2, 3)”, “Purpose of Life (Study 2)”, and “Satisfaction with Life (Study 3)”. A rectangular box at the top labeled “Moderator A I-enabled Interaction (Study 2, 3)” has a vertical downward arrow that intersects the horizontal arrow between “I V” and “Mediator”. This vertical arrow is labeled “H 3” and “H 5” on its left, “H 4” and “H 6” on its right. A rectangular box at the bottom labeled “Moderator A I-enabled Inter-generational Interaction (Study 3)” has a vertical upward arrow labeled “H 7” that also intersects the horizontal arrow between “I V” and “Mediator”.Conceptual model.
