Measures of career skills and cognitive development, for example, focus specifically on development and provide a place for you and your psychologist to begin talking about change. Other tests, such as personality inventories and instruments, which measure family dynamics, environmental stresses and psychiatric problems, are not focused specifically on development but can be used to guide patients toward change. Test results reveal both strengths and limitations, providing a starting point for how strengths compensate for limitations.

For example, when a patient takes a test that reveals a tendency to take criticism harshly, he will know to attempt to solve problems related to being criticized in a new way. Results also reveal strengths, which can assist with problem solving. When a patient takes a test that shows he has an aptitude for social engagement, he can exploit this advantage by applying it to solving problems

Essentially, tests teach people about themselves, and with a psychologist guiding a patient in understanding the test results, simply gaining insight can be a powerful advantage in making progress in treatment. Tests also provide the advantage of establishing a starting point for educating a patient on aspects of mental health in general. With test results specifically relevant to the patient, a psychologist knows the type of information the patient needs to learn in order to make
