Consultation and Supervision
Cognitive Processing Therapy

Dr. Oliver has opened up a limited number of spots for Cognitive Processing Therapy (CPT) for Spring and Summer 2024. CPT is a manualized evidence-based treatment for Post-Traumatic Stress Disorder and can be done in person or through telepsychology. Should you wish to discuss CPT, please contact Dr. Oliver directly.


Cognitive Processing Therapy (CPT) is a cognitive-behavioural treatment for post-traumatic stress disorder (PTSD). Dr. Oliver will first assess you to ensure that you meet the criteria for a diagnosis of PTSD.


CPT consists of 12 individual (one-on-one) therapy sessions. Each session lasts 50–60 minutes. In these sessions, you will learn about the symptoms of PTSD and why we believe that some people develop it. You and Dr. Oliver will also identify and explore how your trauma(s) have changed your thoughts and beliefs, and how some of these ways of thinking may keep you “stuck” in your symptoms. 


CPT does not involve repeatedly reviewing the details of your trauma(s). However, you will be asked to write about your experiences in order to understand how they have affected your thoughts, feelings, and behaviors.


The overall goals of CPT are to improve your PTSD symptoms, and associated symptoms such as depression, anxiety, guilt, and shame. It also aims to improve your day-to-day living.


Perhaps the most important expectation of CPT is for you to make a commitment to come to sessions. In addition, after each session you will be given practice assignments to complete outside of the sessions. These assignments are designed to improve your PTSD symptoms more rapidly outside of the treatment sessions. Dr. Oliver asks that you make a commitment to attend 12 consecutive weekly appointments, however, this may vary slightly.


CPT has been thoroughly evaluated for use in many different populations including Canadian Military Veterans.

Psycho-Diagnostic Assessment

Psycho-Diagnostic Assessments are conducted by individuals trained in psychological assessment. They provide clients with diagnostic clarification and treatment planning.

A Psycho-Diagnostic Assessment is a collaborative process between the client and Dr. Oliver that can help to figure out specific areas of functioning that might be challenging for the individual and that the individual might want to work on in therapy/treatment. 

During this assessment, the client will be guided through several questions about different areas of their mental health, psychological and personality functioning. Questions asked are standardized and have undergone rigorous testing to ensure they are properly assessing areas of functioning in an evidence-based manner. Some questions will be answered in a simple yes or no manner and others will require more detailed responses. Dr. Oliver will support each client in answering any questions that are more difficult to respond to. 

A report will be then written based on the information provided and will include comprehensive holistic treatment recommendations. Following the assessment, the client will be invited to a feedback session in which they will learn about any diagnoses that were formally made and implications for treatment. During the feedback session, the client will be able to read through the report and provide any further information that they feel will be helpful. 

In order to have a psychological assessment completed, a client can be self-referred or referred by a physician.

Dr. Oliver provides psycho-diagnostic assessments for adults presenting with anxiety, mood, personality, and trauma concerns and a variety of other presenting clinical issues. Typically, psycho-diagnostic assessments are helpful in cases involving a history of multiple diagnoses, complex presentations, ineffective treatment experiences or limited treatment progression, and diagnostic debates.

The costs associated with this type of assessment will be determined based on the complexity of your referral question and history, amount of clinical records to review, and availability of collateral reporting. Please speak with Dr. Oliver for questions pertaining to cost and to schedule a quick phone consultation to determine appropriateness.
