A Primary Care-Based Psychosocial Intervention To Improve Cognitive & Depression Outcomes in Older Adults With MCI & Early Stage AD

The purpose of the study is to examine the effect of Problem Adaptation Therapy for Pain (PATH-Pain) on cognitive functioning, depression and pain-related disability in 100 older adults with cognitive impairment, chronic pain, and depression. The study will test if PATH-Pain has better cognitive, affective, and functional outcomes than Attention Control Usual Care.

This is a Randomized Control Trial to target cognition in older adults with MCI or Early AD, depression, and chronic pain with a psychotherapeutic intervention in primary care. This project will study the efficacy of 8 in-office acute treatment sessions (first 8 weeks) and 6 telephone delivered sessions (3 individual and 3 group) in the following months (from 9-36 weeks) of PATH- Pain vs. an equal number of sessions consisting of Attention Control Usual Care in improving cognitive, affective, and functional outcomes. Each therapy session will last approximately 50 minutes. Assessments will be conducted at study entry and weeks 5, 9 (end of acute treatment; includes assessment of cognitive functioning), 24, 36 (end of follow-up treatment; includes assessment of cognitive functioning) and 52 (includes assessments of cognitive functioning) after randomization. This is an efficacy trial, but by being delivered by certified mental health clinicians, it has a strong "real-world" focus.
