Association of Social Work Boards (ASWB) Clinical Practice Exam

The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) is the most appropriate assessment tool for determining a client's global functioning according to the DSM-5. This tool provides a comprehensive framework for measuring disability across various dimensions of functioning, including cognition, mobility, self-care, and interpersonal relationships. It is designed to assess the impact of health conditions on functional activities and is aligned with the biopsychosocial model, which encompasses biological, psychological, and social factors contributing to a person's overall functioning.

WHODAS 2.0 captures both the severity of disability and the individual's perceived ability to function in daily life, making it a valuable asset for clinicians in assessing global functioning. Its standardized format allows for consistent and reliable evaluation across different populations and settings, thus helping clinicians to tailor treatment approaches and monitor progress over time.

Other assessment tools listed, such as the Global Assessment of Functioning Scale (GAF), while previously utilized, are not used in the DSM-5. The Myers-Briggs Type Indicator is focused on personality types rather than functioning. The Thematic Apperception Test is a projective psychological test that explores themes and emotions rather than providing a measure of global functioning.
