Psychological Tests

General Description

Psychological tests are standardized instruments used to measure or evaluate one or more psychological and cognitive characteristics of an individual. They are based on both observable and non-observable behavior and the subjective expression of the individual. From their results, it is possible to infer particular aspects related to a person’s personality, intellect, behavior, and mental state.

Psychological assessments can be classified according to various factors. One of the most well-known classifications is that of Pervin, which categorizes them as follows:

• Psychometric tests: Focus on the quantitative measurement of cognitive abilities and personality traits using structured and standardized questions. An example is the Wechsler Intelligence Scale.
• Objective tests: Structured tests whose results do not depend on the evaluator’s interpretation but are based on physiological correlates. This category includes cognitive, motor, and psychophysiological tests.
• Subjective tests: Assess the most personal and emotional aspects of an individual. They depend on the examinee’s responses regarding their own thoughts and behaviors.
• Projective tests: Based on psychoanalysis, these tests are characterized by open-ended questions and unstructured stimuli, where the examinee projects their responses. A well-known example is the Rorschach Test.

Additionally, psychological tests are classified based on their content, meaning the specific aspect of the psyche they aim to evaluate:

• Intelligence tests: Measure intellectual capacity, adaptability, and understanding of the environment.
• Aptitude tests: Evaluate an individual's abilities in specific areas.
• Personality tests: Assess behavior, emotions, and thoughts that shape how a person perceives and interacts with the world.
• Psychopathology tests: Used to diagnose mental disorders and conditions.
• Neuropsychological tests: Help determine an individual’s mental and perceptual state, especially after an injury.
• Developmental/aging tests: Measure the degree of cognitive development or deterioration.
• Interest or vocational tests: Analyze individual preferences to provide career or interest guidance.

When Are They Indicated?

Psychological tests are indicated in different contexts:

• Clinical settings: Used to assess and diagnose mental disorders, design personalized treatment plans, and monitor patient progress.
• Educational settings: Used to evaluate both students' cognitive abilities and academic aptitudes, as well as their vocational interests and emotional well-being.
• Workplace settings: Utilized in personnel selection processes to measure candidates’ skills and aptitudes, identifying their suitability for a role.
• Research: Serve as standardized tools for measuring psychological variables and obtaining quantitative data that can support statistical analysis or scientific theories on human behavior.

How Are They Conducted?

The administration of a psychological test depends on its specific type:

• Verbal tests require oral or written responses, while non-verbal tests are based on graphic, tactile, or behavioral elements.
• Structured tests contain closed-ended questions, such as multiple-choice or rating scales, where the examinee selects the most appropriate response. Unstructured tests, on the other hand, allow free responses, enabling individuals to express their thoughts, feelings, or experiences openly.

Additionally, test administration methods vary based on their purpose. In clinical assessments, tests are conducted individually in a consultation setting, following a personal interview with a psychologist. In other cases, such as hiring processes, multiple individuals may complete the test simultaneously.

Risks

Although psychological tests are highly valuable tools for gaining insights into human behavior and cognition, they may be influenced by cultural or linguistic biases that affect the reliability or validity of the results. Similarly, a patient’s emotional state at the time of taking the test can impact outcomes.

In projective tests, the subjective interpretation of results by the evaluator plays a significant role in the diagnosis. Therefore, a high level of experience and training is essential to ensure precise and consistent interpretations.

What to Expect from a Psychological Test

Before starting a psychological test, the patient will receive detailed instructions from the evaluating specialist. In some cases, depending on the test’s objective, they will also be informed about its purpose and the implications of their responses.

It is extremely important that the patient answers truthfully and does not alter the information. Otherwise, the diagnosis derived from the test results will be inaccurate.

During the test, individuals may experience fatigue, mental exhaustion, or emotional distress, especially if sensitive topics are involved. If necessary, the specialist may suggest taking a break before continuing.

The duration of psychological tests varies significantly. Depending on the test type and the individual’s response speed, they can take anywhere from 15 minutes to several hours. Once completed, the specialist analyzes the results and prepares a report with their conclusions, which is then communicated to the patient or the relevant administrators.
