Step-by-step explanation:
The publication that dramatically changed the field of psychology and introduced the five-part multiaxial system is the Diagnostic and Statistical Manual of Mental Disorders (DSM). The edition released in 1980 is referred to as the DSM-III.
The DSM-III revolutionized the classification of mental illness by providing a standardized framework for diagnosing and categorizing psychiatric disorders. It introduced the multiaxial system, which included different axes for assessing clinical symptoms, personality disorders, and psychosocial stressors.
The DSM-III was widely influential and remained in use until it was revised in 2013 with the release of the DSM-5.
