The correct answer is option 'C': Personality of the practitioner does not contribute towards ethical standards in psychotherapy.

Explanation:

Ethical standards in psychotherapy are a set of guidelines and principles that therapists follow to ensure the well-being and best interests of their clients. These standards are established to maintain professionalism, protect clients' rights, and provide a safe and effective therapeutic environment. There are several factors that contribute to ethical standards in psychotherapy, and the personality of the practitioner is not one of them.

1. Confidentiality: Confidentiality is a fundamental principle in psychotherapy. Therapists are required to maintain the privacy and confidentiality of their clients. This means that therapists cannot disclose any information shared by the client without their informed consent, except in certain circumstances where there is a risk of harm to self or others.

2. Integrity of the practitioner: Integrity refers to the honesty, trustworthiness, and adherence to ethical principles by the therapist. It involves acting in the best interests of the client, maintaining professional boundaries, and avoiding conflicts of interest. Practitioners with high integrity are more likely to provide ethical and responsible care to their clients.

3. Professional competence: Professional competence refers to the therapist's knowledge, skills, and abilities in their area of practice. It includes staying updated with the latest research and evidence-based practices, engaging in professional development, and seeking supervision or consultation when needed. Professional competence ensures that therapists provide effective and appropriate interventions to their clients.

4. Personality of the practitioner: While the personality of the therapist may influence their therapeutic style and approach, it does not directly contribute to ethical standards in psychotherapy. Ethical standards are based on professional guidelines and principles, not on personal traits or characteristics. It is important for therapists to have a professional demeanor and to separate their personal feelings and biases from their therapeutic work.

In conclusion, while confidentiality, integrity of the practitioner, and professional competence are essential contributors to ethical standards in psychotherapy, the personality of the practitioner does not directly contribute to these standards.
