Inwald Personality Inventory

Last updated

The Inwald Personality Inventory (IPI) is a standardized personality test of adult pathology and personality. The IPI is utilized by public safety services to assess the fit of possible employees in public safety and law enforcement positions. The assessment can also indicate deviant behavior patterns.

Contents

The original IPI was created by Dr. Robin Inwald in 1980, and was published by Hilson Research. An updated version, the IPI-2, was released in 2011 by the Institute for Personality and Ability Testing, Inc. (IPAT). Original items from the IPI were reorganized in the creation of the current edition. While the IPI-2 features diagnostic criteria, it is not meant to be used as a mental health disorder diagnostic tool.

History and use

IPI

The original IPI was created in 1980 by Dr. Robin Inwald and was published by Hilson Research. The assessment was created as a screening tool for applicants in high-risk positions, such as police candidates. The assessment was developed from over 2,500 pre-employment interviews with public safety officer candidates. Part of the purpose of the IPI was to counter the use of psychopathology tests, such as the MMPI, for the use of public safety selection tests. 310 true/false questions were implemented in the test. IPAT’s Public Safety and Security Division acquired the assessment in March of 2007, requiring clinicians to pay a fee every time it was administered. The assessment contained one validity scale (Guardedness) and 25 clinical scales:

IPI-2

The IPI-2 was released by the Institute for Personality and Ability Testing, Inc. (IPAT) in 2011. Items from the original IPI were reviewed for fit for the current revision, resulting in some items being removed because they were outdated and provocative by 21st century standards. Other items were reorganized into newly formulated content scales. The IPI-2 was created using a normative sample of 89,301 preexisting and rescored IPI records from the United States. 78.5% of this sample were male, and 21.5% were female. Ethnicities that are represented in the sample are as follows: 61.5% Caucasian, 19.4% African American, 13.3% Hispanic, 2.8% Native American, 2.3% Asian, and 0.6% Other. While these percentages could seem skewed, this ratio is representative of gender and ethnic percentages of public safety applicants according to the 2000 U.S. Census.

The assessment is made up of 202 true/false questions that are self-reported. Like its predecessor, the IPI-2 continues to measure characteristics or patterns of behavior that are unfavorable for those in high-risk professions. The assessment is fit for individuals who are ages 16 and older, and who have a minimum of a fifth-grade reading level. The assessment takes 30 to 40 minutes to complete, and is available in English, French, and Spanish. The assessment can always be taken by hand, but is now also available through the IPAT’s online service or on OnSite Pro software. The IPI-2 contains 16 content scales and 1 validity scale (Guardedness):

* - Validity Scale

Scoring and Interpretation

Scoring for the IPI-2 involves comparison of scores with those of other public safety professionals in an effort to better predict proper fit for applicants. Scores for each scale are scores using T-scores, and those scores that are above a t-score of 60 are considered to be “elevated”, thereby warranting further exploration.

In testing validity of the IPI-2, internal consistency was measured using Cronbach’s Alpha (overall=0.52). Significant correlations (<.05) were analyzed between IPI-2 scales and MMPI-2-RF and the PAI (Personality Assessment Inventory).

Results are combined with Field Training Officer (FTO) Predictions, in order to provide a more complete analysis. Results from FTO Predictions, coupled with IPI-2 results that were used in discriminant function analysis, lead to one of two outcomes for the categories of Control of Conflict, Public Relations, Report Writing, and Overall FTO Rating. The two outcomes for each of these categories are: ″likely to meet expectations″ or ″not likely to meet expectations″.

Psychometrics is a field of study within psychology concerned with the theory and technique of measurement. Psychometrics generally refers to specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. Psychometrics is concerned with the objective measurement of latent constructs that cannot be directly observed. Examples of latent constructs include intelligence, introversion, mental disorders, and educational achievement. The levels of individuals on nonobservable latent variables are inferred through mathematical modeling based on what is observed from individuals' responses to items on tests and scales.

Psychological testing is the administration of psychological tests. Psychological tests are administered by trained evaluators. A person's responses are evaluated according to carefully prescribed guidelines. Scores are thought to reflect individual or group differences in the construct the test purports to measure. The science behind psychological testing is psychometrics.

The Minnesota Multiphasic Personality Inventory (MMPI) is a standardized psychometric test of adult personality and psychopathology. Psychologists and other mental health professionals use various versions of the MMPI to help develop treatment plans, assist with differential diagnosis, help answer legal questions, screen job candidates during the personnel selection process, or as part of a therapeutic assessment procedure.

Thematic apperception test (TAT) is a projective psychological test developed during the 1930s by Henry A. Murray and Christiana D. Morgan at Harvard University. Proponents of the technique assert that subjects' responses, in the narratives they make up about ambiguous pictures of people, reveal their underlying motives, concerns, and the way they see the social world. Historically, the test has been among the most widely researched, taught, and used of such techniques.

<span class="mw-page-title-main">Personality test</span> Method of assessing human personality constructs

A personality test is a method of assessing human personality constructs. Most personality assessment instruments are in fact introspective self-report questionnaire measures or reports from life records (L-data) such as rating scales. Attempts to construct actual performance tests of personality have been very limited even though Raymond Cattell with his colleague Frank Warburton compiled a list of over 2000 separate objective tests that could be used in constructing objective personality tests. One exception however, was the Objective-Analytic Test Battery, a performance test designed to quantitatively measure 10 factor-analytically discerned personality trait dimensions. A major problem with both L-data and Q-data methods is that because of item transparency, rating scales and self-report questionnaires are highly susceptible to motivational and response distortion ranging all the way from lack of adequate self-insight to downright dissimulation depending on the reason/motivation for the assessment being undertaken.

In social science research, social-desirability bias is a type of response bias that is the tendency of survey respondents to answer questions in a manner that will be viewed favorably by others. It can take the form of over-reporting "good behavior" or under-reporting "bad", or undesirable behavior. The tendency poses a serious problem with conducting research with self-reports. This bias interferes with the interpretation of average tendencies as well as individual differences.

<span class="mw-page-title-main">Strong Interest Inventory</span>

The Strong Interest Inventory (SII) is an interest inventory used in career assessment. As such, career assessments may be used in career counseling. The goal of this assessment is to give insight into a person's interests, so that they may have less difficulty in deciding on an appropriate career choice for themselves. It is also frequently used for educational guidance as one of the most popular career assessment tools. The test was developed in 1927 by psychologist Edward Kellog Strong, Jr. to help people exiting the military find suitable jobs. It was revised later by Jo-Ida Hansen and David P. Campbell. The modern version of 2004 is based on the Holland Codes typology of psychologist John L. Holland. The Strong is designed for high school students, college students, and adults, and was found to be at about the ninth-grade reading level.

Throughout his nearly 60-year career, Meehl made seminal contributions to psychology, including empirical studies and theoretical accounts of construct validity, schizophrenia etiology, psychological assessment, behavioral prediction, and philosophy of science.

The California Psychological Inventory (CPI) is a self-report inventory created by Harrison G. Gough and currently published by Consulting Psychologists Press. The text containing the test was first published in 1956, and the most recent revision was published in 1996. It was created in a similar manner to the Minnesota Multiphasic Personality Inventory (MMPI)—with which it shares 194 items. But unlike the MMPI, which focuses on maladjustment or clinical diagnosis, the CPI was created to assess the everyday "folk-concepts" that ordinary people use to describe the behavior of the people around them.

The Millon Clinical Multiaxial Inventory – Fourth Edition (MCMI-IV) is the most recent edition of the Millon Clinical Multiaxial Inventory. The MCMI is a psychological assessment tool intended to provide information on personality traits and psychopathology, including specific mental disorders outlined in the DSM-5. It is intended for adults with at least a 5th grade reading level who are currently seeking mental health services. The MCMI was developed and standardized specifically on clinical populations, and the authors are very specific that it should not be used with the general population or adolescents. However, there is evidence base that shows that it may still retain validity on non-clinical populations, and so psychologists will sometimes administer the test to members of the general population, with caution. The concepts involved in the questions and their presentation make it unsuitable for those with below average intelligence or reading ability.

<span class="mw-page-title-main">Psychopathy Checklist</span> Psychopathy scale

The Psychopathy Checklist or Hare Psychopathy Checklist-Revised, now the Psychopathy Checklist—revised (PCL-R), is a psychological assessment tool that is commonly used to assess the presence and extent of the personality trait psychopathy in individuals—most often those institutionalized in the criminal justice system—and to differentiate those high in this trait from those with antisocial personality disorder, a related diagnosable disorder. It is a 20-item inventory of perceived personality traits and recorded behaviors, intended to be completed on the basis of a semi-structured interview along with a review of "collateral information" such as official records.

Psychological evaluation is a method to assess an individual's behavior, personality, cognitive abilities, and several other domains. A common reason for a psychological evaluation is to identify psychological factors that may be inhibiting a person's ability to think, behave, or regulate emotion functionally or constructively. It is the mental equivalent of physical examination. Other psychological evaluations seek to better understand the individual's unique characteristics or personality to predict things like workplace performance or customer relationship management.

The Sixteen Personality Factor Questionnaire (16PF) is a self-report personality test developed over several decades of empirical research by Raymond B. Cattell, Maurice Tatsuoka and Herbert Eber. The 16PF provides a measure of personality and can also be used by psychologists, and other mental health professionals, as a clinical instrument to help diagnose psychiatric disorders, and help with prognosis and therapy planning. The 16PF can also provide information relevant to the clinical and counseling process, such as an individual's capacity for insight, self-esteem, cognitive style, internalization of standards, openness to change, capacity for empathy, level of interpersonal trust, quality of attachments, interpersonal needs, attitude toward authority, reaction toward dynamics of power, frustration tolerance, and coping style. Thus, the 16PF instrument provides clinicians with a normal-range measurement of anxiety, adjustment, emotional stability and behavioral problems. Clinicians can use 16PF results to identify effective strategies for establishing a working alliance, to develop a therapeutic plan, and to select effective therapeutic interventions or modes of treatment. It can also be used within other areas of psychology, such as career and occupational selection.

The Narcissistic Personality Inventory (NPI) was developed in 1979 by Raskin and Hall, and since then, has become one of the most widely utilized personality measures for non-clinical levels of the trait narcissism. Since its initial development, the NPI has evolved from 220 items to the more commonly employed NPI-40 (1984) and NPI-16 (2006), as well as the novel NPI-1 inventory (2014). Derived from the DSM-III criteria for Narcissistic personality disorder (NPD), the NPI has been employed heavily by personality and social psychology researchers.

Post-traumatic stress disorder (PTSD) is an anxiety disorder that may develop after an individual experiences a traumatic event. In the United States, the Social Security Administration and the Department of Veterans Affairs each offer disability compensation programs that provide benefits for qualified individuals with mental disorders, including PTSD. Because of the substantial benefits available to individuals with a confirmed PTSD diagnosis, which causes occupational impairment, the distinct possibility of Type I errors exists, some of which are due to malingering of PTSD.

The Psychopathic Personality Inventory (PPI-Revised) is a personality test for traits associated with psychopathy in adults. The PPI was developed by Scott Lilienfeld and Brian Andrews to assess these traits in non-criminal populations, though it is still used in clinical populations as well. In contrast to other psychopathy measures, such as the Hare Psychopathy Checklist (PCL), the PPI is a self-report scale, rather than interview-based, assessment. It is intended to comprehensively index psychopathic personality traits without assuming particular links to anti-social or criminal behaviors. It also includes measures to detect impression management or careless responding.

Computer-based test interpretation (CBTI) programs are technological tools that have been commonly used to interpret data in psychological assessments since the 1960s. CBTI programs are used for a myriad of psychological tests, like clinical interviews or problem rating, but are most frequently exercised in psychological and neuropsychological assessments. CBTI programs are either empirically based or clinically based. The empirically based programs, or actuarial assessment programs, use statistical analyses to interpret the data, while the clinically based programs, or automated assessment programs, rely on information from expert clinicians and research. Although CBTI programs are successful in test-retest reliability, there have been major concerns and criticisms regarding the programs' ability to assess inter-rater and internal consistency reliability. Research has shown that the validity of CBTI programs has not been confirmed, due to the varying reports of individual programs. CBTI programs are very efficient in that they save time, reduce human error, are cost effective, and are objective/reliable, yet limited in that they are not always used by adequately trained evaluators or are not integrated with multiple sources of data. As technology continues to transform our modern society, computer-based interpretation programs have the possibility to expand their software and even alleviate some of the current concerns with the programs' methodology.

The Lees-Haley Fake Bad Scale (FBS) or MMPI Symptom Validity Scale is a set of 43 items in the Minnesota Multiphasic Personality Inventory, selected by Paul R. Lees-Haley in 1991 to detect malingering for the forensic evaluation of personal injury claimants. It was endorsed by the MMPI publishers in 2006 and incorporated into the official scoring keys. A 2008 Wall Street Journal article noted that a few psychologists argued that it was controversial because they felt that some individuals with legitimate injuries would be categorized as faking bad.

A validity scale, in psychological testing, is a scale used in an attempt to measure reliability of responses, for example with the goal of detecting defensiveness, malingering, or careless or random responding.
