Attribution theory explains how people make judgments about the causes of their and other people's behaviors. In therapy, attribution theory can help patients identify and change their attributional style, which refers to the patient's tendency to attribute the causes of events or situations to certain factors. Negative self-attributions are often associated with an attributional style that is internal, stable, and global.
The goal of therapy using attribution theory is to help the patient recognize and change their attributional style to more positive and adaptive patterns.

Providing comprehensive information and allowing for questions ensures that consent is informed, voluntary, and based on a clear understanding of the study, aligning with ethical guidelines for research.
Providing the information necessary to obtain informed consent is the clinician's responsibility. While institutional review boards play a role in approving a clinical trial, they are not directly responsible for obtaining informed consent from participants. Coercing participation by threatening to discontinue treatment is unethical and violates the principle of voluntariness in informed consent. Although incentives can be used in research, they should not be so significant that they unduly influence the participant's decision, compromising the voluntariness of consent.
