A psychiatric disability exists when a person is mentally impaired by a psychiatric disorder. Impairment can be partial or total, temporary or permanent, and must be taken in the context of performance of varying types of tasks. For example, can a job be performed (or performance in a particular occupation)? Carrying out tasks of daily living? The assessment of the psychiatric impairment requires a psychiatric evaluation. The scope of the psychiatric evaluation is situation-specific. The assessment of Psychiatric Disability usually requires a review of medical records, face-to-face examination if possible, appropriate psychometric testing, and a review of relevant collateral information, e.g. deposition testimony, investigative reports, interviews with other interested parties.
- Ability to work in any occupation. (With special applications regarding the Defense Base Act, Longshore and Harbor Workers, Railroad Act, Social Security Disability)
- Ability to work in a specific occupation. (Disability Insurance, Workers’ Compensation, Fitness for Duty)
- Ability to work if specified and reasonable accommodations are provided by the employer (Americans with Disabilities Act – ADA).
- Ability to work after a specific event which allegedly caused the psychiatric disability (Personal Injury, Harassment, Discrimination).
[An aside: In personal injury cases, an event which is alleged to have triggered or exacerbated a mental health condition is clarified by a forensic assessment. Is a diagnosed psychiatric disorder present, did it preexist or follow an alleged ‘triggering event’, did the event worsen a preexisting illness? How does a mental health disability affect that person’s post-event life. A psychiatric condition can be disabling but treatable, or be an issue of damages yet not be a Disability (capital D) as defined under any number of administrative criteria (Social Security Disability Benefits, for example)].
