HomePsychological Assessment

Psychological testing is the administration of psychological tests, which are designed to be “an objective and standardized measure of a sample of behavior”. The term sample of behavior refers to an individual’s performance on tasks that have usually been prescribed beforehand.

Performance on these items produce a test score. A score on a well-constructed test is believed to reflect a psychological construct such as achievement in a school subject, cognitive ability, aptitude, emotional functioning, personality, etc. The science behind psychological testing is psychometrics.

A psychological test is an instrument designed to measure unobserved constructs, also known as latent variables. Psychological tests are typically, but not necessarily, a series of tasks or problems that the respondent has to solve. Psychological tests can strongly resemble questionnaires, which are also designed to measure unobserved constructs, A useful psychological test must be both valid (i.e., there is evidence to support the specified interpretation of the test results) and reliable (i.e., internally consistent or give consistent results over time, across raters, etc.).

Psychological assessment is similar to psychological testing but usually involves a more comprehensive assessment of the individual. Psychological assessment is a process that involves checking the integration of information from multiple sources, such as tests of normal and abnormal personality, tests of ability or intelligence, tests of interests or attitudes, as well as information from personal interviews.

A psychological test is one of the sources of data used within the process of assessment; usually more than one test is used. Many psychologists do some level of assessment when providing services to clients or patients, and may use for example, simple checklists to osis for treatment settings; to assess a particular area of functioning or disability often for school settings; to help select type of treatment or to assess treatment outcomes; to help courts decide issues such as child custody or competency to stand trial; or to help assess job applicants or employees and provide career development Counselling or training.

The first large-scale tests may have been examinations that were part of the imperial examination system in China. The test, an early form of psychological testing, assessed candidates based on their proficiency in topics such as civil law and fiscal policies. Other early tests of intelligence were made for entertainment rather than analysis. Modern mental testing began in France in the 19th century. It contributed to separating mental retardation from mental illness and reducing the neglect, torture, and ridicule heaped on both groups Englishman Francis Galton coined the terms psychometrics and eugenics, and developed a method for measuring intelligence based on nonverbal sensory-motor tests. It was initially popular, but was abandoned after the discovery that it had no relationship to outcomes such as college grades.

French psychologist Alfred Binet, together with psychologists Victor Henri and Théodore Simon, after about 15 years of development, published the Binet-Simon test in 1905, which focused on verbal abilities.

The origins of personality testing date back to the 18th and 19th centuries, when personality was assessed through phrenology, the measurement of the human skull, and physiognomy, which assessed personality based on a person’s outer appearances.

One of the earliest modern personality tests was the Woolworth Personality Data Sheet, a inventory developed for World War I and used for the psychiatric screening of new draftees.
