cognitive rehabilitation for veterans with mdd-related cognitive functioning deficits

Conditions: Major Depressive Disorder (MDD); Cognitive Dysfunction

Summary: individuals with depression often describe difficulties with memory, attention, concentration, and overall cognitive functioning, which can persist even after mood episodes get better, and can affect treatment and health outcomes. the primary objective of this pilot clinical trial is to evaluate the feasibility and acceptability of a manualized, 8-week, compensatory cognitive training (cct) intervention for veterans who received treatment for mdd in the past year and have persistent cognitive functioning deficits. the investigators will compare motivationally enhanced compensatory cognitive training for major depressive disorder (me-cct-mdd) to a robust comparator, goal-focused supportive contact (gsc), to evaluate differences in outcome measures. the investigators hypothesize that motivationally enhanced compensatory cognitive training for major depressive disorder (me-cct-mdd) will be feasible and acceptable to participants in a pilot trial of me-cct-mdd vs. goal-focused supportive contact (gsc) for veterans with recent mdd treatment and persistent cognitive symptoms. this study will also evaluate the preliminary magnitude and direction of symptom change on measures of objective cognitive functioning, psychiatric symptomatology, psychosocial functioning, and quality of life. the investigators hypothesize that cct will improve objective cognitive functioning, psychiatric outcomes, psychosocial functioning, and quality of life in veterans with recent mdd-related cognitive functioning deficits. participants who agree to participate in the study will: 1. take part in an assessment of their cognition, symptoms, and functioning, which will take approximately 2 hours. the assessment will include an interview about their medical, psychiatric, and cognitive history. it will also include questionnaires about their symptoms and daily functioning as well as neuropsychological tests, which are paper-pencil tests that evaluate aspects of cognition such as memory, attention, and problem-solving skills. 2. be randomly assigned (like the flip of a coin) to receive goal-focused supportive contact or compensatory cognitive training. both treatments will involve weekly groups with a mental health provider for approximately 2 hours per week for 8 weeks. goal-focused treatment includes setting and achieving short-term and long-term goals for improving cognition and functioning. compensatory cognitive training includes training in strategies to improve cognition and manage stress. 3. complete a follow-up assessment of cognition, symptoms, and functioning 8 weeks after they begin treatment, as well as a brief interview about their experience in the group. these assessment sessions will take approximately 2 hours.

motivationally enhanced compensatory cognitive training for major depressive disorder (me-cct-mdd) is a manualized group-based behavioral intervention (8 weeks, 2 hours per week) designed to improve cognitive functioning in veterans with major depressive disorder (mdd) and cognitive complaints. me-cct-mdd is an adaptation of cct initially developed by clinicians and researchers at the va portland healthcare system and the va san diego healthcare system. cct draws from the empirical and theoretical literature on compensatory strategy training for conditions characterized by cognitive complaints and impairments, including mild traumatic brain injury, psychosis, and mild cognitive impairment. me-cct-mdd is a comprehensive treatment in that it addresses multiple types of symptoms and concerns that interfere with recovery from depressed mood episodes - cognitive impairments, neuropsychiatric symptoms, and lifestyle patterns that increase the risk of cognitive impairment, poor health, and mdd relapse. in addition to training in compensatory cognitive skills, me-cct-mdd includes mindfulness practices and motivational interviewing techniques to boost the adoption of lifestyle strategies (e.g., nutrition, exercise) that improve cognition and overall health. me-cct-mdd is designed to be easy to administer and as an adjunct to standard mdd treatment programs. given the high rate of mdd among veterans, the prevalence of cognitive impairments among those with mdd, and the negative impact of cognitive impairments on vocational functioning, psychosocial functioning, quality of life, and treatment outcomes, an evidence-based cognitive training intervention that optimally addresses the complex needs of veterans with mdd and cognitive impairments is of critical importance. this study will allow the investigators to assess the feasibility and acceptability of the me-cct-mdd intervention in preparation for a larger-scale pilot randomized control trial.
