Which principle should psychologists follow regarding fees when referring clients?

Accepting payment only for services rendered aligns with ethical standards of practice in psychology, specifically those outlined in various professional codes of conduct. This principle upholds the integrity of the therapeutic relationship and prioritizes the best interests of clients. By only accepting payment for actual services provided, psychologists maintain professional boundaries and avoid potential conflicts of interest that could arise from referral commissions or flat fees that may not correspond to tangible service delivery.

Charging a flat fee for all referrals does not account for the variability in services provided and could mislead clients about the nature and scope of care they are receiving. Similarly, allowing commissions based on referrals could compromise the objectivity of a psychologist's professional judgment and push them to prioritize financial gain over client welfare. Adhering strictly to the principle of receiving payment only for services ensures that ethical considerations remain central to practice.
