Modified Prolonged Exposure Therapy for Posttraumatic Stress Disorder with an 85-Year-Old Native American Cajun Man With Late-Onset Deafness: A Case Report.

Objectives: Few studies of exposure therapy with adults 85 years and older exist. This case report presents results of prolonged exposure (PE) for posttraumatic stress disorder (PTSD) modified for an 85-year-old Native American Cajun man with late-onset deafness, who used a cochlear implant, and reported high Western/non-Native American acculturation. The following modifications were made primarily in response to the client's individual, disability-related barriers to completing the standard PE protocol: (a) inclusion of the client's spouse in aspects of treatment planning and homework assignments; (b) variable session length and frequency; (c) homework was limited to the daily practice of breathing retraining and in vivo exposure to triggering images; and (d) therapist reliance on nonverbal indicators of distress during imaginal exposures.

Methods: The PTSD Checklist for DSM-5 (PCL-5) and 15-item Geriatric Depression Scale (GSD-15) were primary progress and outcome measures.

Results: The modified treatment was associated with clinically significant decreases in baseline PTSD (19 points) and depressive (8 points) symptoms.

Conclusions: PE protocol modifications did not compromise treatment outcomes for this client.

Clinical implications: PE protocols should be modified based on the individual needs of diverse older adults underrepresented in efficacy research.
