Standard 3.05 of the APA ethics code outlines the definition of multiple relationships.
[4][5][6] Several "helping" fields which are not strictly psychological in nature, but which still involve a therapeutic counseling environment, also have stringent policies involving dual relationships and the avoidance of such relationships.
For example, the National Association of Social Workers [NASW], which regulates 132,000 social workers across the world, names multiple types of dual relationships.
[7] This includes sexual, financial, personal or religious relationships which could become exploitative due to the differences in power between the worker and the client.
Social workers are advised by the NASW to communicate with their clients when such a relationship arises or could arise, and are advised to take steps to avoid dual relationships wherever possible.
