RecruitingBehavioural interventionA Study of Meaning-Centered Psychotherapy for Caregivers to People With CancerParticipants will complete 1 set of questionnaires about 2 weeks before beginning their Meaning-Centered Psychotherapy for Caregivers/MCP-C or standard Supportive Psychotherapy for Caregivers/SP-C sessions. These questionnaires will ask about participants' sense of meaning and purpose in life, spiritual well-being, depression and/or anxiety, and social support. Participants will then be assigned to receive either MCP-C or SP-C for 7 sessions. Participants will complete additional sets of questionnaires about 2 weeks, 6 months, and 12 months after their last session of MCP-C or SP-C. It will take between 35 and 50 minutes to complete each set of questionnaires. After participants complete the MCP-C or SP-C sessions and all 4 sets of questionnaires, their participation in this study will end. If participants decide not to complete all 7 sessions, they may still choose to complete the questionnaires. Participants may remain in the study and continue to receive all 7 sessions of MCP-C or SP-C even if their loved one passes away.
