Different Types of Psychological Assessments

Psychological Assessment

Psychological assessment is defined by Cohen et al. (2022) as “the gathering and integration of psychology-related data for the purpose of making a psychological evaluation that is accomplished through the use of tools such as tests, interviews, case studies, behavioral observation, and specially designed apparatuses and measurement procedures” (p. 3). In other words, it is a process of using a wide range of tools and methods, each designed to identify and understand the specific aspects of a person’s psychological profile. Beyond the tools stated by Cohen et al. (2022) in their definition, there are self-report questionnaires, performance-based measures, projective tests, physiological measures, ecological momentary assessment (EMA), and dynamic assessments—all of which help the psychologist to gain a picture of the client, where the client’s mental health is on the health spectrum, and identify areas of potential concern.

The tools and methods of gathering data in the field of psychological assessment are all different in their own rights. Psychological tests are standardized instruments that can be used to measure for a specific construct—such as intelligence or personality traits, or there are tests that have been shown through research and evaluation to be able to test for specific mental health conditions. Examples of such tests include the Wechsler Adult Intelligence Scale (WAIS) for assessing intelligence and the Minnesota Multiphasic Personality Inventory (MMPI) for evaluating personality traits. These tests are useful for giving statistical data that can be used in the overall evaluation process.

Interviews are much different in that these tests are more subjective in terms of how data is interpreted. Interviews can be structured, which means they follow a pre-arranged form; or they can be semi-structured, or even unstructured. Each type has its own uses Structured interviews, like the Structured Clinical Interview for DSM Disorders (SCID), follow a set of questions useful for making a diagnosis. Semi-structured and unstructured interviews are more flexibility, and are useful for exploring a client’s personality (Cohen et al., 2022).

Behavioral Observations are conducted by observing the client’s behavior usually in a natural setting, such as in the client’s home or else in a controlled environment. These are a good way to see how the person interacts with his environment, which helps the psychologist obtain data that might not be readily apparent in a standardized test or interview.

Case Histories are another good assessment which involves compiling detailed information about the person’s background, including medical history, education, family history, and life experiences. It provides a lot of context for the psychologist to better understand the current mental state of the client and can help in identifying patterns or factors that might be influencing the client’s behavior (Cohen et al., 2022).
