10 commonly used psychological assessments

Sometimes, meeting with a client in therapy isn’t enough for a therapist to know what is going on. You are seeing someone out of her regular context, moved into a intrusive (though supportive) environment. You aren’t the same self in therapy as you are the rest of the time, so it can be good to get a closer look at traits and symptoms. If your therapist needs more insight into your situation, he might request that you take one or a series of assessments. Following are some of the most widely used ones.

1. Clinical interviews
Clinical interviews are a series of set questions that focus on any symptoms you may have, helping the clinician better assess if you have a diagnosable disorder. During the interview, you will be asked open-ended questions. The interviews generally last between 30 minutes and two hours. Sometimes, the clinician that is administering the test will assess 
attitudes, appearances and behaviors in order to 
supplement the verbal answers given.

2. Screening inventories 
A screening inventory is an assessment that is looking at client symptoms and distress. They can be used both to diagnose mental illnesses and to look at therapy progress and outcomes, depending on the test and context you are taking it in. For instance, the Outcome Questionnaire-45 (OQ-45) can be used before each session to check in on where the client is at. The Beck Depression Inventory (BDI) might be used to get a better handle on a client’s depression symptoms. The Symptom Checklist-90-R (SCL-90-R) might be used to look at a number of symptom clusters while conducting a psychological study. There are a wide variety of tests to suit many purposes.

3. Rorschach test
The Rorschach test (also known as the inkblot test) is perhaps the most famous psychological test of all time. It is a projective assessment wherein the subject is shown a series of symmetrical images created by ink on paper. The subject says what she sees in the images and the test administrator will write down everything, no matter how trivial it may seem. These statements are later interpreted in regards to personality, emotional functioning and to detect thought disorders. 

4. Thematic Apperception Test (TAT)
The TAT is another projective assessment. In this one, the subject is shown ambiguous images of people. The client will tell the proctor stories about the individuals the pictures, which can be interpreted in a multitude of ways. This test is considered a glimpse into the subconscious and the way people see the world. It has been used to study a variety of items, such as motives, concerns, personality and emotional stability. 

5. Rotter Incomplete Sentence Blank (RISB)
A third commonly used projective test is the RISB. In this assessment, the subject is given a list of 40 sentence stems, or incomplete sentences. These are deliberately vague and encompass such phrases as, “I need…,” “Other people…” and “My greatest fear…”. The subject simply completes the sentences however he wants. There is not much in terms of standardized scoring, but themes will emerge, such as a preoccupation with ones appearance or social anxiety. These can help the therapist better tailor treatment to areas of concern.

The WAIS, currently in its fourth edition, is an intelligence test. It measures raw intelligence and gives you an IQ score. The average IQ is 100. It focuses on a variety of areas, including working memory, processing speed, arithmetic and vocabulary. It has questions ranging from picture completion to finding similarities between words. This test measures your aptitude, not how well you are actually doing in the areas tested.

7. Woodcock-Johnson Tests of Cognitive Abilities
The Woodcock-Johnson, in contrast to the WAIS, is made to measure cognitive performance. It shows how well you actually do in the areas of math, reading and writing. You may score higher or lower than your actual IQ would indicate; for this reason, it can be useful in identifying learning disorders. 

8. Minnesota Multiphasic Personality Inventory (MMPI)
The MMPI is the most commonly used psychological test. It is used to assess personality and psychopathology. Depending on the version of the test you take, you answer either 338 or 567 true or false questions about yourself. This is used to gauge your level of pathology in areas such as depression, hysteria and paranoia. Based on the areas you have the highest scores in, a portrait of your personality and psychological issues can be made. There is also an adolescent version of this assessment, the MMPI-A, which is 478 items long.

9. Millon Clinical Multiaxial Inventory (MCMI)
Used strictly to assess psychopathology, the MCMI does not tell you about personality in the same way the MMPI does. It has a clear focus on psychological symptoms, as it identifies personality disorders and clinical syndromes. It is, however, much shorter than the MMPI, only having 175 true or false questions that can generally be answered in 25-30 minutes. The adolescent version of this assessment is called the Millon Adolescent Clinical Inventory (MACI) and is 160 items long.

10. Child Behavior Checklist (CBCL)
This test is designed to be used with minors, starting as young as 18 months of age. A parent or caregiver takes the test and reports social, behavioral and emotional observations of the subject. There are also versions of the test that can be filled out by teachers or the youth themselves. The assessment asks how true certain statements are, such as “talks or walks in sleep” or “acts too young for his/her age.” Because parents and teachers have higher access to the youth than the therapist does, it can be helpful to get input from someone used to seeing the child in other settings.
