Modeling intention to participate in face-to-face and online lung cancer support groups.

BACKGROUND Lung cancer patients and survivors are significantly less likely to use support groups than those with other cancers. In this study, we evaluated the utility and specificity of the Behavioral Model for Vulnerable Populations for modeling intention to participate in face-to-face (F2F) and online lung cancer support groups. METHODS Adults diagnosed with lung cancer (n = 230) completed measures assessing predisposing, enabling, and need factors associated with intention to use support services. RESULTS Intention to join a F2F support group (found among 36.4% of survivors) was associated with positive attitude about F2F support groups, fewer perceived time constraints, less travel time from the clinic, and not having enough social support. Intention to join an online support group (34% of survivors) was associated with having more positive attitudes about online support, greater use of avoidance coping strategies, more comfort using computers, and fewer perceived time constraints. Demographics, medical history, health status, and psychological status were not associated with intention to join either type of group. CONCLUSIONS Reducing barriers to participation and addressing attitudes about support services may be the most effective ways to increase utilization of lung cancer support services.
