What the standard requires: Psychologists provide services, teach, and conduct research with populations and in areas only within the boundaries of their competence, based on their education, training, supervised experience, consultation, study, or professional experience.
A clinician who works with children and families in high-conflict custody settings and cannot identify Child Psychological Abuse under DSM-5 V995.51 is practicing outside the boundaries of their competence. The diagnostic standard exists. The clinical framework exists. Ignorance of both is a competence failure — not an excuse.
The Ethics Exposure
Every clinician who conducts custody evaluations, provides reunification therapy, or works with children in high-conflict custody proceedings without training in DSM-5 V995.51 and the Childress three-indicator framework is practicing outside their competence under Standard 2.01a. This is not a gray area. This is the APA's own standard applied to the APA's own diagnostic code.
