In most jurisdictions, therapists are bound by laws and ethical codes that require them to maintain client confidentiality. This means that therapists are generally not allowed to disclose information shared by their clients during therapy sessions to third parties without the client's consent, except in specific situations where there is a duty to warn or protect the client or others from serious harm.
If a therapist lies to you about their ability to report information in order to elicit information from you and then goes on to disclose that information without your consent, it would be a serious breach of ethical conduct and could be grounds for professional misconduct.
If you have concerns about your therapist's behavior or the handling of your confidential information, it's essential to address those concerns directly with the therapist or the therapy organization if applicable. You can inquire about their confidentiality policies and how they handle disclosures. If you feel uncomfortable discussing certain topics due to fear of potential reporting, consider having an open conversation with your therapist about your concerns. Building a trusting therapeutic relationship is crucial for effective therapy, and open communication is an essential part of that process.
If you ever feel that your confidentiality has been violated or you have experienced unprofessional conduct from a therapist, you have the right to report the issue to the therapist's licensing board or regulatory authority. This step can help ensure that appropriate actions are taken to address the matter.
