have a significant impact on the individual’s treatment and prognosis (American Psychiatric Association, 2013). It can also be used to track changes in the individual’s symptoms presentation over time. Being that Tyrell is 30 years old, the adult version would be best appropriate for use. The adult version contains 23 questions, assessing 13 psychiatric domains. This assessment measure is particularly helpful in Tyrell’s case because the Level 1 Cross-Cutting Symptom Measure assesses the domains of suicidal ideation, depression, anger, and substance use (American Psychiatric Association, 2013). In addition, this measure has been found to be clinically useful. The World Health Organization Disability Assessment Schedule 2.0 is an adult self-administered assessment, which consists of 36-items that assess disability across 6 domains, in adults 18 or older (American Psychiatric Association, 2013). The domains include cognition, mobility, self-care, getting along, life activities, and participation. This assessment would be beneficial in that it can provide a clinician with a bigger picture of what could be going on with Tyrell. Furthermore, the WHODAS 2.0 can be used to track an individual’s level of disability over time (American Psychiatric Association, 2013).
