Which ethical guideline should therapists follow regarding past relationships with clients?

Therapists must adhere to strict ethical guidelines to ensure the integrity of the therapeutic relationship and to protect clients from potential harm. The appropriate guideline regarding past relationships with clients is that therapists should not treat anyone with whom they had a past sexual relationship. This principle helps to prevent conflicts of interest and boundary issues that could arise from previous personal involvement.

Engaging in therapy with a former partner can lead to dual relationships, which are problematic because they may compromise the objectivity and professionalism required in therapy. Such situations can create power imbalances, conflicts of interest, and the potential for exploitation, all of which can undermine the effectiveness of therapy and harm the client's emotional well-being.

By maintaining clear boundaries, therapists foster a safe and confidential environment, allowing clients to engage fully in the therapeutic process without concerns about the therapist's dual roles or past connections. This guideline supports the trust that is essential in the client-therapist relationship and aligns with the overarching goal of ethical clinical practice in marriage and family therapy.
