Psychological testing and evaluation involve a series of tests which are used to identify the causes of mental health symptoms and disorders. It is employed when the underlying problem is unclear, despite apparent symptoms like academic or social difficulties in children or relationship struggles in adults. The evaluation includes aptitude tests, personality assessments, and cognitive screenings. The process typically takes several hours, involving standardized written tests, questionnaires, and interviews with a clinician. The results are used to formulate an overall evaluation, determine a diagnosis, and create a personalized treatment plan.
