FAQ - Testing and Evaluation Psychiatrists
How can psychiatrists help with diagnostic testing and evaluation?
What distinguishes psychiatrists from many other mental health professionals is their training and expertise in conducting comprehensive psychiatric testing and evaluations. These evaluations are essential for accurately diagnosis and treatment of mental health conditions. A psychiatric evaluation typically includes an assessment of a client's current symptoms, mental health history, medical background, family history, and psychosocial factors. Psychiatric testing and evaluation can help clarify diagnoses (e.g., by helping distinguish symptoms of conditions that may appear similarly, such as ADHD and anxiety), guide decisions about appropriate levels of care, and inform medication or therapy interventions. As part of the evaluation process, psychiatrists will often also explore how lifestyle factors like stress, sleep, relationships, and daily routines affect a client's emotional well-being.
How do psychiatrists use evaluation results to guide treatment planning?
Based on the results of their evaluation, psychiatrists work with clients to develop a treatment plan, which may include therapy, lifestyle changes, and psychiatric medication. For younger clients, such as children undergoing testing for learning disabilities, the results may help inform school-based interventions. In other cases, evaluations can help ensure that the psychiatrist prescribes a correct medication based on a clients's symptoms. Testing and evaluation may also help inform what psychotherapy treatment interventions may be most useful, such as Dialectical Behavioral Therapy (DBT) if a patient is evaluated and diagnosed with Borderline Personality Disorder (BPD) or Cognitive Behavioral Therapy (CBT) is a client is diagnosed with depression.
How can I find a psychiatrist who specializes in diagnostic testing and evaluation?
The Psychology Today directory is a helpful resource for finding psychiatrists who specialize in diagnostic testing and evaluations. Using the platform's filters, clients can search for professionals with experience in specific conditions such as mood disorders, trauma, neurodevelopmental conditions, cognitive decline, and other conditions. Clients may also filter by factors such as provider identity, insurance accepted, or availability for telehealth. When reaching out to a psychiatrist, it can be helpful to ask about their experience with evaluation and diagnosis for your concerns, the types of assessments they offer, and how they typically structure treatment planning based on their findings.
