Adjustment disorders in the US military: Addressing Gaps in Knowledge and Practice

Purpose: The purpose of this study is to investigate gaps associated with diagnosing and assessing Adjustment Disorders (AD) in service members. This involves two phases conducted concurrently: (1) establishing a military-specific assessment tool for ADs and (2) exploring provider-focused factors that influence AD diagnosis in military populations for the purpose of modifying the reliable and validated ADNM-20.
Eligibility Criteria: Phase 1C Psychometric Evaluation (Any Active Duty Service Member, 18 or older, English-speaking, and who has not participated in another phase of this study) who: (1) has a diagnosis of Adjustment Disorder alone or Adjustment Disorder with depressed mood, anxiety, or mixed anxiety and depressed mood within the past 12 months OR (2) has never received a diagnosis of Adjustment Disorder or any other mental health or substance use disorders Phase 2b (Providers Only): Provider (e.g., healthcare, behavioral health), age 18 years or older, who diagnoses or treats active duty military service members.
Participant Expectations: Phase 1C (Any Service Member) If you decide to participate in this study you will complete a 20-30 minute packet of online questionnaires, which can also be mailed to you. The questionnaires will ask you about a series of symptoms of various mental health problems to understand how adjustment disorders are experienced in military populations and how they are different from other diagnoses. Phase 2b (Providers Only) If you decide to participate in the study you will complete a short onetime questionnaire that will take approximately 20-30 minutes to complete. The questionnaire will ask you about your attitudes and behaviors as a provider with regards to using a military-specific/focused assessment tool when diagnosing Adjustment Disorders in the Military population.

Summary: If you served in the military after October 2001, you may be eligible to participate in a reserach study requested by Congress. We are currently recruiting service members and veterans who 1) have incurred a TBI since 2001, 2) incurred a bodily injury that was not a TBI since 2011 or 3) have served at any point since 2001 but were not injured.
The purpose of the study is to increase our understanding of the long term effects of trumatic brain injury on service members and veterans. Participation will include short yearly appointments. Each visit will last either 2 hours or 2 days and will occur once per year for up to 15 years. You may elect to participate only in web-based and telephone measures.

Your participant could contribute to knowledge that could improve the care of your fellow service members and veterans. You may be compensated for your participation.
