Final answer:
A multiple relationship refers to situations where a therapist has more than one role or relationship with a client, which can compromise objectivity and effectiveness. The RBT Ethics Code states that having a friendly relationship with a client outside of sessions is not appropriate, while collaborating with a colleague on a work project is acceptable as long as professional boundaries are maintained. Team-building activities with clients may create potential multiple relationships depending on the context.
Step-by-step explanation:
A "multiple relationship" in the context of the RBT Ethics Code refers to situations where a therapist has more than one role or relationship with a client. These relationships can potentially compromise the therapist's objectivity and effectiveness. According to the code, it is not appropriate for a therapist to have a friendly relationship with a client outside of sessions, as this could blur professional boundaries and impact the therapeutic relationship.
Collaborating with a colleague on a work project is not considered a multiple relationship, as long as the interaction is within the professional context and does not involve personal or dual roles.
Team-building activities with clients may also have a potential for multiple relationships, as they can create a social bond beyond the therapeutic relationship. However, it depends on the specific context and the intentions behind the activities. To avoid multiple relationships, it is generally recommended to maintain professional boundaries with all clients.
