Study Arms:
- E-PST (randomized) (Type: EXPERIMENTAL): Enhanced Problem-Solving Training (E-PST) arm. E-PST is a combined treatment that is comprised of brief problem-solving training and compensatory cognitive skills training. Randomized participants were assigned 1:1 to E-PST or HLM.
- Control (randomized) (Type: ACTIVE_COMPARATOR): Healthy Living Messages (Control) arm. Healthy Living Messages (HLM) are primary care-congruent messages that consist of simple advice regarding general health behaviors and preventive care. Randomized participants were assigned 1:1 to E-PST or HLM.
- E-PST (non-randomized) (Type: OTHER): Enhanced Problem-Solving Training (E-PST) arm. E-PST is a combined treatment that is comprised of brief problem-solving training and compensatory cognitive skills training. Non-randomized participants were assigned to E-PST only.

Based on this trial design, predict the completion outcome and termination type (if applicable).
