Chronic tinnitus is defined as nonsensical, persistent sound in the head or ears with no external sound source that persists for more than 6 months.1 It is most commonly associated with sound trauma, aging, head injury, and damage to the ear structures.2 Tinnitus affects up to 30% of military veterans, a prevalence rate that is twice that of the nonveteran population.3 It also is the most common service-connected disability for veterans.4 In 2016, more than 1.6 million veterans had service-connected tinnitus.

Clinical management of tinnitus is the purview of audiologists, although their role in providing this service is not well defined.5 Following an audiologic evaluation for hearing loss, devices such as hearing aids, ear-level sound generators, or sounds played through speakers may be prescribed. However, effectiveness of these devices has been shown only when coupled with counseling.6 Counseling provided by audiologists often includes education about tinnitus etiology, maintaining hearing health, and use of sound to manage tinnitus. Length, content of care, and follow-up services vary among audiologists.

Given the importance of counseling and the added complexities of mental health and behavioral health comorbidities (eg, depression, anxiety, sleep disorders), various psychological therapies delivered by mental health specialists for tinnitus management have been explored.7-11 In fact, only psychological therapies have been documented to be efficacious for mitigating the negative effects of tinnitus on sleep, concentration, communication, and emotions.12 Among these approaches, cognitive behavioral therapy (CBT) has the strongest empirical support, particularly in terms of improving quality of life (QOL) and reducing depressive symptoms.11,12 Cognitive behavioral therapy for tinnitus is derived from social cognitive theory (SCT) and modeled after CBT for depression, anxiety, pain, and insomnia.11,13-15

Cognitive behavioral therapy helps patients with tinnitus reconceptualize the auditory problem as manageable and encourages acquisition, practice, and use of a range of specific tinnitus coping strategies to enhance perceptions of self-control and self-efficacy. Cognitive behavioral therapy involves a number of distinct therapeutic components, and there is no consensus about the efficacious components of CBT for tinnitus. For example, use of sound and purposeful exposure to tinnitus varies among providers.16 Additional questions about CBT pertain to its clinical implementation (eg, group vs individual sessions, frequency and length of sessions, in-person sessions vs delivery via telephone or Internet).

Programs offered at the Department of Veterans Affairs (VA) facilities take veteran-specific factors into account to promote optimal engagement and outcomes. Factors that differentiate veterans from civilians include (1) increased probability of low health literacy and low socioeconomic status among seniors17; (2) increased likelihood of acoustic and/or psychological trauma3,18; (3) overrepresentation of males; and (4) increased probability of mental health diagnoses.19,20 At the same time, veterans are highly diverse with respect to age, academic achievement, cultural background, medical and mental health comorbidities, and economic resources.17 In spite of this diversity, most veterans are unified by their sense of camaraderie, loyalty to country, and adherence to discipline and order.21 Peer support and other variables such as compassionate understanding of their military experiences may be especially important to consider when designing behavioral interventions for veterans.

The present phenomenologic study was motivated by the need to develop and test a veteran-specific CBT for tinnitus protocol (VET CBT-T). To examine veterans’ experiences with VET CBT-T, we designed a small pilot randomized controlled trial (RCT) of VET CBT-T comparing it to structured audiologist counseling (AC). A mixed quantitative and qualitative approach was employed, including assessing veterans’ acceptance of care, identifying aspects that can be modified to improve outcomes, and obtaining feasibility data to guide refinements to VET CBT-T to inform a larger RCT.
