Clinical Trial Summary

This study will evaluate the efficacy of Problem Adaptation Therapy (PATH) vs. Supportive Therapy for Cognitively Impaired (ST-CI) older adults in reducing depression and disability in treating depressed, cognitively impaired older adults.

Description:

Depression, cognitive impairment, and disability often coexist in older adults and can lead to patient suffering and family disruption. Moreover, many depressed, cognitively impaired older adults have slow, poor, or unstable response to antidepressant drugs. Despite the need for treatments other than medication, most psychotherapy research focuses on either cognitively intact patients with limited disability or on dementia patients with pronounced disability. Thus, the available treatments do not fully address the needs of the large number of depressed elders with intermediate cognitive impairment and disability. Previous studies with cognitively impaired psychiatric populations have taught participants compensatory strategies to overcome their behavioral and cognitive limitations. This study will evaluate the efficacy of Problem Adaptation Therapy (PATH) a type of psychotherapy using a problem solving therapy (PST) approach, specially tailored compensatory strategies and environmental adaptations and caregiver involvement in treating depressed, cognitively impaired older adults.

All participants in this single-blind study will undergo initial evaluations, including a 2-hour interview to assess depression, memory, and physical functioning; questions about medical history; and a neuropsychological exam. Participants will then be randomly assigned to one of two treatment groups: PATH or ST-CI. Participants assigned to PATH will receive 12 weekly sessions conducted at the home of the participants. During these sessions, a therapist will identify the participant's difficulties in life related to depression and physical functioning and will provide strategies to overcome these difficulties. The goal of treatment is to improve adaptive functioning in the home environment, which in turn may reduce depression and disability. The first session will last between 1 and 2 hours, and the remaining 11 sessions will last 1 hour. Participants assigned to ST-CI will also receive 12 weekly treatment sessions with a therapist conducted at the home of the participants. During supportive therapy sessions, the therapist will help participants to express feelings and to focus on their strengths and abilities when working through difficulties and transitions. For all participants, initial assessments will be repeated at Weeks 4, 8, 12, and 24.

Related Conditions & MeSH terms

• Depression

Intervention

Behavioral:
• PATH
PATH utilizes a problem solving approach based on Problem Solving Therapy (PST) and identifies problems that interfere with everyday functions and that contribute to depression and disability. The treatment then provides compensatory strategies and environmental adaptations that are designed to bypass the person's cognitive limitations and to improve adaptive functioning in the home environment. PATH also incorporates caregiver involvement to help patient reduce depression and improve functioning.
• Supportive Therapy for Cognitively Impaired Older Adults (ST-CI)
Supportive therapy focuses on the use of nonspecific or common factors of therapy, including facilitation of affect, helping the person feel understood, empathy, the treatment ritual, success experiences, and therapeutic optimism. In working with the participant, the therapist creates a supportive relationship and encourages the participant to consider his/her strengths and abilities rather than focusing on negative aspects of his/her character.
