The Purpose of the Psychological Evaluation

Before undergoing bariatric surgery, patients should be evaluated to assess psychiatric or psychological issues that might affect the outcome of surgery, or a person's ability to cope with the necessary lifestyle changes. The psychological evaluation can be an important tool in determining what a particular person might need from a mental health perspective for a successful outcome and a healthy adjustment. Psychological evaluations can be powerful tools to assist in the diagnosis, treatment, or management of any mental health or behavioral problems that could adversely affect the outcome if left unassessed or untreated. As a result of the evaluation the psychologist may make specific recommendations designed to support a successful post-operative adjustment.

Psychological Evaluations Assess:

• The presence of any current relevant psychiatric diagnoses or problems that might adversely affect the outcome or require further treatment before pursuing weight reduction surgery. 
• The possibility of a chemical dependency or other addictive disorder 
• Whether the patient can provide informed consent to the procedure
• Whether the patient sufficiently understands the nature of the procedure and the necessary lifestyle changes crucial for a successful outcome
• Whether the person's expectations and goals are realistic and attainable
• The level of social support versus social stress a person might experience
• Personality strengths and weaknesses, such as coping style, tolerance for stress, and the ability to assert oneself appropriately with others with respect to maintaining commitment to dietary and other lifestyle changes
• The risk of the person engaging in unhealthy 'symptom substitution' for over-eating or other compulsive behavior
