Before providing one service jointly to several clients (for example a couple, family, group or other system), psychologists must consider and record why that mode suits every client involved. Effective practice means the psychologist: (a) takes reasonable steps so that each client consents without undue pressure from the others; (b) takes reasonable steps so that the joint format does not undermine the safety or effectiveness of the service for any client; (c) gives every client a safe and effective service; and (d) respects and protects every client's privacy and confidentiality under the code's other provisions.
