Subjects were 34 computer programmers employed in a major computerized tax processing company. Scores in the Computer Programmer Aptitude Battery (CPAB) and ratings of each programmer's job performance by his immediate supervisor were obtained. The purpose of the study was to validate a selection test. The relationship between the aptitude battery and performance evaluations was examined to evaluate the test's ability in predicting programming performance. Statistical treatment of data included Pearson product-moment correlations and a multiple linear regression analysis. The total test scores and several of the subtests were found to be significantly correlated with performance.

Professional school counselors frequently use career interest inventories as part of a comprehensive guidance program to help students create a post-secondary school plan. The present study evaluates the validity of three commonly used interest inventories, the Myers-Briggs Type Indicator, Self-Directed Search, and Strong Interest Inventory on field of study choice for graduating high school seniors (N = 616) from a large, suburban high school in Texas. Students identified their intended postsecondary field of study category, were randomly assigned using stratification to three groups, and each group completed a different inventory. Group membership was evaluated to establish covariate balance on a wide variety of indicators. Data from each group was evaluated to determine the extent to which the inventory predicted the chosen field of study, as well as Other and Undeclared categories using logistic regression models. None of the inventory models suggest that the inventory accurately predicts Other or Undeclared outcomes. For students selecting intended postsecondary fields of study, the Self Directed Search predicts such outcomes better than other measures. Professional school and career counselors should consider the SDS in addition to narrative counseling strategies to add greater precision with career decision making among clients and students.

This research is an investigation into the Apil B as a culture fair assessment tool for the purpose of recruitment and selection. The Employment Equity Act stipulates that "psychological testing and other similar assessments are prohibited unless the test or assessment being used :-a) has been shown to be valid and reliable b) can be fairly applied to all employees and c) is not biased against any employee" (Employment Equity Act, 1998). The primary objective of this research is to evaluate the Apil B with regard to validity. reliability, cultural fairness, and bias via a consideration of the attitudes, opinions, and feelings of psychometric test administrators in the Kwa-Zulu Natal region. The secondary objective is to ascertain whether the Employment Equity legislation has influenced the attitudes of test administrators toward psychometric testing, and the implications for psychometric testing in South Africa following the Act. The sample in this research consists of 20 qualified test administrators of the Apil B. The administrators are affiliated with the following companies : Beacon, Durban Electricity, Profiled Appointments, Mondi, McCann and Associates, Saunders and Associates, Tetrapak, lthaJa, and Mangosuthu Technikon. Qualitative and quantitative methods are used. A self-administered questionnaire is used to investigate the attitudes, opinions, and feelings of the respondents toward the Apil B as a culture fair assessment, specifically in relation to validity, reliability, cultural fairness, and bias. Although most of the questions are qualitative, quantitative questions are also included. Therefore, this research requires numerical data as well . The quantitative questions include yes and no responses, as well as rating scales. The quantitative data supplements the qualitative data and therefore facilitates a more concrete data base. The results indicate that all respondents feel that the Apil B is valid, reliable, culture fair and fairly applied . Respondents feel more positively toward the new updated psychometric tests. They expressed greater confidence in terms of knowing which tests are inappropriate and which tests are relevant to specific jobs. It is also evident that the Employment Equity Act has strongly influenced the attitudes of respondents, in a very positive light, toward the use of psychometric testing. The respondents do however mention some concerns with regard to language based tests, and the ethical use of tests. According to the research conducted, the Apil B is regarded as a valid, reliable, and culture fair assessment tool in the opinion of the respondents utilised in this study. It is therefore recommended that the Apil B is used in organisations as a test that does not discriminate against any culture or subculture. / Thesis (M.A.)-University of Natal, Durban, 2000.

There is a dire need for psychological tests to be standardized for the African child and for appropriate norms to be developed. This study is part of two larger studies that began in 2008, namely the National Early Learning Standards Age Validation Study (NELDS) (Kvalsvig, Govender & Taylor; 2008) (Principal Investigator – Dr. S. Kauchali), and the INSTAPA Work Package 6 Study (Kvalsvig, Govender & Taylor; 2008) (Principle Investigator – Dr. J.D. Kvalsvig). This study considers aspects of the Kilifi Development Inventory (KDI) as a measurement tool used to provide a structured and standardized procedure for monitoring the cognitive development of children from the age of 6 to 35 months. It is situated in the positivist paradigm and has adopted the classical test theory in attempting to establish the reliability of the Kilifi Developmental Inventory. Stratified purposive sampling techniques were used to select the South African sample, which comprised 120 participants categorized by gender (males and females), age (6 – 18 months and 18 – 35 months) and area (urban and peri urban/rural). The internal reliability of the KDI was investigated. Results from the data analysis (using SPSS 18.0) suggest that the measurement tool as a whole had inadequate internal reliability and therefore, further investigations and modifications have to be undertaken in certain subtests of the measurement tool before the assessment tool can be standardized for the South African population. / Thesis (M.Soc.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2011.

Thesis (MComm (Industrial Psychology))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: The last two decades have witnessed an upsurge in the research and use of psychometric tests to aid in the prediction of managerial performance. Currently the most prevailing predictor constructs of managerial performance are cognitive ability, personality, and experience. However, researchers and practitioners are still looking for ways in which to maximise the prediction of managerial performance. In recent years, Situational Judgement Tests (SJTs) have become an increasingly popular selection tool. SJTs are multidimensional psychometric instruments designed to assess an individual’s judgement concerning work-related situations. Evidence to date indicates that SJTs are valid predictors of performance, especially for managerial positions in which interpersonal interactions are important. The main objective of this study was to examine whether SJTs significantly add to the prediction of managerial performance over other measures used for managerial selection, such as measures of cognitive ability and personality. Measures of specific cognitive abilities, personality and a SJT were administered to branch managers in a South African retail bank (N = 124) to investigate the ability of the measures to predict managerial performance. Managerial performance was measured using three measures; Performance Ranking, a Behavioural Observation Scale (BOS) and an Overall Performance Rating. Hierarchical multiple regression was used to investigate the relationship between the predictor composites and the managerial performance measures. Findings reveal different prediction patterns for the three criteria. A multiple correlation coefficient of .442 (p > .05) was obtained when predicting Performance Ranking measures, .308 (p < .05) was obtained for predicting the Behavioural Observation Scale (BOS) measure, and .318 (p > .05) was obtained when predicting the Overall Performance Rating measure. Therefore, only when predicting the BOS measure, the SJT provided incremental validity over cognitive ability and personality measures. Consequently, the average of the scores of the three criterion measures, i.e., the Managerial Performance Composite, was used to evaluate the a priori hypotheses. A multiple correlation of .366 (p > .05) was obtained for predicting the Managerial Performance Composite criterion. Results therefore indicate that the SJT did not exhibit meaningful or statistically significant incremental prediction over cognitive ability and personality to predict the composite managerial performance measure. / AFRIKAANSE OPSOMMING: Die laaste twee dekades het ‘n toename in die gebruik van psigometriese toetse in die voorspelling van bestuurdersprestasie waargeneem. Tans is kognitiewe vermoë, persoonlikheid en ervaring die mees algemene voorspellingskonstrukte vir bestuurdersprestasie. Navorsers en praktisyns is egter op soek na maniere om die voorspelling van bestuurdersprestasie te verbeter. ‘n Onlangse verwikkeling is dat “Situational Judgement Tests” (SJTs) toeneem in gewildheid as seleksie-metode. SJTs is multi-dimensionele psigometriese toetse wat ontwerp is om ‘n individu se oordeelsvermoë ten opsigte van werksverwante situasies te assesseer. Navorsing tot op hede wys dat SJTs geldige voorspellers van prestasie is, veral vir bestuursposisies waarin interpersoonlike interaksies belangrik is. Die hoofdoel van hierdie studie was om te ondersoek of SJTs betekenisvolle waarde toevoeg tot die voorspelling van bestuurdersprestasie bo die gebruik van ander meetinstrumente wat vir bestuurskeuring gebruik word, soos metings van kognitiewe vermoë en persoonlikheid. Vir hierdie doel, is takbestuurders in ‘n Suid Afrikaanse bank (N = 124) se kognitiewe vermoëns, persoonlikheid en situasionele beoordelingsvermoë getoets om die vermoë van die meetinstrumente om bestuurdersprestasie te voorspel, te ondersoek. Bestuurdersprestasie was deur middel van drie meetinstrumente bepaal; prestasie-rangordening (“Performance Ranking”), ‘n gedragsobservasieskaal (“Behavioural Observation Scale”) en ‘n algehele prestasiebeoordelingsmeting (“Overall Performance Rating”). Hiërargiese meervoudige regressie-ontleding was gebruik om die verhouding tussen die voorspellers en die bestuurdersprestasiemetings te ondersoek. Verskillende voorspellingspatrone is vir die drie meetinstrumente gevind. ‘n Meervoudige korrelasie koeffisiënt van .308 (p < .05) is vir die voorspelling van die BOS meting verkry, terwyl .442 (p > .05) en .308 (p < .05) onderskeidelik vir die voorspelling van die prestasie-rangordening en algehele prestasiebeoordelingsmeting verkry is. Gevolglik het slegs die BOS meting inkrementele geldigheid getoon. Die gemiddeld van hierdie drie metings se tellings is gebruik om ‘n bestuurdersprestasie-kombinasietelling “Managerial Performance Composite” te skep wat gebruik is om die finale besluit rakende die a priori hipoteses te maak. ‘n Meervoudige korrelasie van .366 (p >.05) was gevind ten einde die bestuurdersprestasie-kombinasietelling te voorspel aan die hand van die voorspellers.

Some basic but desirable employability skills are antecedents of job performance. The Workplace Skills Survey (WSS) is a 48-item situational judgment test (SJT) used to assess non-technical workplace skills for both entry-level and experienced workers. Unfortunately, the psychometric evidence for use of its scores is far from adequate. The purpose of current study was two-fold: (a) to examine the proposed structure of WSS scores using confirmatory factor analysis (CFA), and (b) to explore the WSS item functioning and performance using item response theory (IRT). A sample of 1,018 Jamaican unattached youth completed the WSS instrument as part of a longitudinal study on the efficacy of a youth development program in Jamaica. Three CFA models were tested for the construct validity of WSS scores. Parameter estimations of item difficulty, item discrimination, and examinee’s proficiency estimations were obtained with item response theory (IRT) and plotted in item characteristics curves (ICCs) and item information curves (IICs). Results showed that the WSS performed quite well as a whole and provided precise measurement especially for respondents at latent trait levels of -0.5 and +1.5. However, some modifications of some items were recommended. CFA analyses showed supportive evidence of the one-factor construct model, while the six-factor model and higher-order model were not achieved. Several directions for future research are suggested.

New Spanish versions of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and the Personality Assessment Inventory (PAI) were assessed with the Spanish translation of the Diagnostic Interview Schedule (DIS) as the gold standard. Findings from categorical and dimensional analyses suggest that, although the degree of diagnostic concordance of both measures with the DIS was found to be moderately high, the MMPI-2 clinical scales yielded greater specificity but lower sensitivity than the PAI scales on two of four diagnostic categories (i.e., Major Depression, and Schizophrenia). Both measures failed to correctly diagnose Anxiety Disorders, while the MMPI-2 also showed poor diagnostic accuracy with Alcohol Dependence.
