In this assignment I choose the Myers-Briggs Type Sign (MBTI) to review (Fleenor, 1998). The MBTI is based on Jung’s (1923) theory of internal traits and was created in 1942 by a mother child team, Katharine Briggs and Isabel Myers, in order to operationalize Jung’s theory. The Mental Measurements Yearbook reports that no additional personality inventory in history has become as trusted as the MBTI can be today.

Description of the MBTI

Purpose and Design

The MBTI, which may be used on virtually any male or female older than 18, analyzes psychological or personality types on four dimensions: Extroversion/Introversion, Sensing/Intuition, Thinking/Feeling, and Judging/Perceiving (Cross Swiatek). The MBTI classifies these kinds of four categories as followed: (1) Introverts are more inside oriented and extroverts are more externally focused. Therefore , introverts will feel drained by interpersonal encounters while extroverts will certainly gain energy from interpersonal encounters. (2) Sensing types tend to gain information generally through the feelings whereas User-friendly types think more abstractly and look for concealed meanings. (3) Thinking types are reasonable and organized thinkers, viewing lots of things in bipolar dimensions, although Feeling types are better at perceiving, analyzing, and understanding the emotions of others. (4) Finally, judging types will be organized, they plan anything out, plus they enjoy having control of most circumstances. Perceiving types are natural, flexible, and open-minded people who adapt well at most conditions. This check can be used to support individuals gain self-insight, or help specialists better figure out their clientele.


The MBTI can be described as self-report set of questions written by a seventh-grade reading level and includes 94 forced-choice items upon four zweipolig discontinuous scales (Chamorro-Premuzic et al., 2007). After completing this evaluation individuals are categorized into one of 16 personality types based upon their maximum score in each of the 4 dimensions. For example , if an individual scores bigger on Expansion than Introversion, Intuition than Sensation, Pondering than Sense, and Perceiving than Judging, then that individual would be classified as a great Extroverted, User-friendly, Thinking, Perceiving type.

Standardization Sample

In order to analyze and weigh the products on the MBTI, a national sample representative of U. H. adults over the age of 18 was used (Fleenor, 1998). Nevertheless, this sample comprises more of old individuals, females, and Caucasians; thus, extreme caution should be considered when interpretation MBTI benefits (Hess, 2002).

Psychometric Houses


Stability refers to interior consistency, or the extent to which a evaluation or measurement produces precisely the same scientific remark each time it truly is applied (Hess, 2002). The MBTI offers demonstrated various forms of trustworthiness, such as test-retest reliability and Alpha coefficient reliability.

Test-retest reliability has become demonstrated making use of the MBTI (Fleenor, 1998). Three samples of people were given the MBTI ensure that you were asked to retake this test four weeks afterwards. Their tastes for the four dichotomies were then analyzed. The results showed that 54% to 80% (an normal of 65%) of members reported the same preferences about both testing. In addition , the authors of the MBTI manual report a number of studies credit reporting the MBTI’s Alpha rapport, which range from. 57 to. eighty-five with a typical of. 77 (Hess, 2002).


Quality refers to empirically supported interpretations of a test out (Hess, 2002). The MBTI has exhibited various kinds of validity, such as predictive quality, construct validity, concurrent quality, and heuristic validity.

Predictive validity has become demonstrated between the MBTI and two steps of intellect: the Graduate Management Evaluation (GMA-A), which usually measures both equally fluid and crystallized intelligence, and the Watson-Glaser Critical Pondering Appraisal (WGCTA), which steps crystallized brains (Chamorro-Premuzic ou al., 2007). The results of this research, which was conducted on 3500 males and females possessing managerial positions, found which the MBTI’s measures of persona type is a significant predictor of intellect scores on the GMA – A and WGCTA.

Additionally , the creators of the MBTI manual statement the construct validity with the MBTI’s four factor model using conformity factor evaluation (Fleenor, 1998). The 4 factor model was compared to two additional competing versions and was found as the best fit for the data. Furthermore, the MBTI manual studies a number of other research which demonstrate the MBTI’s concurrent quality by assessing its facet and choice scales into a number of different personality actions (such as the A bunch of states Psychological Inventory, Fundamental Interpersonal Relations Orientation-Behaviour, Eysenck Individuality Questionnaire, plus the Rotter Locus of Control Scale) (Hess, 2002). The majority of these side by side comparisons demonstrated correlations which were inside the expected way.

Finally, within a Mental Measurements Yearbook Review of the MBTI, it was declared this test has heuristic validity mainly because for a split century it has been one of the most well-known tools applied is counselling and career settings (Hess, 2002).

Make use of MBTI in Clinical Configurations

A number of research have been done on the use of personality testing among guidance students (Freeman et approach., 2007). Virtually all these studies have discovered that persona types or traits of counselling college students have a statistically significant impact of the type of psychotherapeutic approach that they choose to make use of. That being said, Freeman et ing. did not locate the same results. That they conducted a report on 132 counselling learners by having all of them complete the MBTI check along with the Self-Directed Search (SDS), which procedures personality and career passions (e. g. investigative, imaginative, conventional, and so forth ). In addition , the scholar’s preferences for psychotherapeutic techniques were established using the Counsellor Educators Review (CES) which usually classified 18 of the key psychotherapeutic approaches into one of three extensive categories (i. e. efficient, behavioural, and cognitive). The results on this study had been calculated making use of the Discriminant Function Analysis, a device that is used to predict and explain “the relationships that impact the class in which a subject is located” (Freeman ou al., 3 years ago, p. 259). This analysis found that neither the MBTI nor the SDS predicted different types of psychotherapeutic techniques. Although these kinds of results contradict those present in a number of other studies, the test was created differently. While previously mentioned, Freeman ainsi que al. labeled 18 in the major psychotherapeutic approaches into one of three broad groups, whereas the other studies used several. The researchers stated that some restorative approaches might not exactly have been showed adequately by one of the three classifications. For instance , solution-focused and solution-oriented were two beneficial approaches that have been less evidently classified.

In addition , it is stated in the Mental Measurements Yearbook the fact that results with this test can be a useful tool pertaining to instigating and encouraging open dialog between a counsellor and a client (Hess, 2002). Too, counsellors are able to use this test out can help their very own clients gain valuable self-insight and understand individual variations in themselves and more (Fleenor, 1998).

Strengths and Weaknesses


The Mental Measurements Yearbook states the MBTI is known as a useful tool for helping persons understand differences in personality type and boost self-insight (Fleenor, 1998). Furthermore, the test’s long-held recognition among experts is sited as one of the strengths, along with the MBTI manual itself, which is well written and possesses extensive info, including in-depth knowledge means interpret test results (Hess, 2002). Finally, the test has been praised being a tool which usually works as a government for dialogue in counselling and career settings.

Weak points

The Mental Measurements Yearbook states that the MBTI cannot be fully recommended until extra analysis is usually conducted intended for categorical data (Fleenor, 1998). The creators of the MBTI manual anxiety that this evaluation is not meant to measures personality traits over a continuous scale; but rather, it can be designed to kind individuals into types. However, the writers frequently statement studies within their manual that utilize constant scores because evidence of the instrument’s validity and reliability. In addition , the Mental Measurements Yearbook declares that further validational research, particularly in the area of predictive validity, should be carried out before the results of this test are used to generate clinical, job, or forensic decisions (Hess, 2002). Finally, in terms of the standardization sample used, although considered an agent sample of U. S. adults over the age of 18, the sample is weighted more towards elderly individuals, females, and Caucasians. Thus, extreme caution is advised once interpreting these kinds of results for individuals that do not get caught in any of these categories (Hess, 2002).
