Family caregivers in the attention control study arm will receive three sessions of attention-matched control in addition to the services and support provided as part of usual outpatient palliative care. Attention-matched control will consist of three "friendly visits" with a trained research staff person.

Family caregivers in the intervention study arm will participate in three problem-solving therapy sessions with a trained interventionist in addition to receiving the services and support provided as part of usual outpatient palliative care.

Each year of the project, the investigators will recruit 6 key stakeholders to participate in individual interviews focused on potential barriers and facilitators to adoption of the PST intervention into clinical practice for a total of 30 unique stakeholders who will be interviewed over the duration of this 5-year study.

Over an approximately 3-week period, family caregivers randomized to the intervention study arm will learn and apply a problem-solving approach based on the ADAPT model, which encourages participants to follow five steps when solving caregiving problems: 1) focus on adopting a positive attitude to problem solving, 2) define the problem and set goals, 3) generate a list of alternative solutions to the problem, 4) predict consequences of the alternative solutions, and 5) try implementing the most promising solution from among the list of alternatives. The intervention will be delivered by a trained interventionist over the course of three structured sessions via telephone or videoconferencing technology, depending on the FCG's preference. Session content will be summarized in an intervention manual, which we will provide to all intervention participants. Sessions will last approximately 45-60 minutes.

Family caregivers indicate the frequency with which they experience eight different symptoms of anxiety (8 items); higher scores reflect higher anxiety severity.

Family caregivers indicate the frequency with which they experience eight different symptoms of depression (8 items); higher scores reflect higher depression severity

• Family caregivers indicate good things that they experience as a caregiver with seven different statements. The caregivers answer with 1=I disagree with this statement a lot; 2=I disagree with this statement a little; 3=I neither agree nor disagree with this statement; 4=I agree with this statement a little; or 5=I agree with this statement a lot.
• Higher scores indicate a more positive caregiving experience
