Participants completed a single, 60-minute semi-structured interview on Zoom following a standardized guide in three parts: 1) sharing a recent positive experience; 2) describing recent in-person interactions with acquaintances and with strangers, including emotional responses, comfort, and experiences discussing their cancer; and 3) reviewing and giving feedback on three image sets (peers experiencing loneliness, peers experiencing connectedness, and spaces where connection could occur) and two mock intervention messages shown as social media posts with a personal story, intervention text, and behavioral tips.
