This four-part webinar seeks to enhance the clinician's ability to diagnose child mental disorders accurately and comprehensively. We will address two major topic areas: 1) the key factors in accurate assessment, including developmental perspectives, the use of multiple data sources and standardized assessment tools; and 2) major diagnostic categories, including disruptive behavior, reactive attachment disorder and early character dysfunction in children. The workshop will include didactic presentation and case-centered group exercises. Participants are strongly encouraged to bring sample vignettes that illustrate diagnostic difficulties and puzzles. It is suggested that participants bring a copy of the DSM-5, if possible. *This is a four-part webinar, attendees must attend all four sessions to receive a certificate of completion.
