When facilitating change in the behavior of a client diagnosed with a personality disorder, the nurse knows which intervention will have the greatest impact on success?

Choice A reason: Regular assessments are important for monitoring progress, but they do not directly facilitate behavioral change. They are supportive measures rather than the primary driver of success. Choice B reason: Collaboration in establishing treatment goals empowers the client, fosters motivation, and increases adherence. Personality disorders often involve resistance to authority and difficulty with trust, so involving the client in goal-setting enhances engagement and ownership of the therapeutic process. This makes collaboration the most impactful intervention. Choice C reason: Educating the client about compliance is helpful, but compliance alone does not ensure behavioral change. Without active collaboration, education may feel directive and fail to address the client’s underlying resistance. Choice D reason: Understanding the etiology of medications is useful for knowledge, but it does not directly influence behavioral change. Personality disorders require psychosocial interventions more than pharmacological explanations.
