According to the Professional and Ethical Compliance Code for Behavior Analysts clients have the right to refuse or terminate services at any time While it can be disappointing a BCBA must respect the clients autonomy and decision Option D demonstrates ethical conduct by immediately accepting the clients decision with professionalism It also includes the appropriate step of offering assistance with referrals which aligns with supporting the clients continued wellbeing without forcing services Option A is incorrect because clients are generally not legally or ethically bound to a notice period for termination they can terminate immediately Option B is incorrect as it constitutes refusing to terminate services when requested which is a form of abandonment if the client no longer desires services and it overrides their right to choose While BCBAs must avoid abandonment this applies to the BCBA unilaterally terminating not the client choosing to stop Option C while wellintentioned is unethical as it attempts to manipulate or coerce the client into continuing services against their wishes infringing on their right to selfdetermination
