A multiple replication of the three-factor solution of the Eysenck personality inventory identified using a two-step confirmation and the factor replication procedure,FACTOREP

For more than 20 yr there has been argument over the precise factor structure of the Eysenck Personality Inventory (EPI). There has recently been some empirical support for the suggestion that this failure to find the original structure is a result of the discrepancy in size between the Neuroticism and Extraversion scales (24 items each) and the Lie scale with nine items. In a recent study the present authors identified the three-factor structure using a two-step process which involved a two-factor analysis of the Neuroticism and Extraversion items followed by a three-factor analysis of an equal number of items from all three scales. This process was repeated in the present study across the responses from two further independent subjects groups. The factor comparison procedure FACTOREP provided strong evidence of the robust and consistent replications of both the two-factor structure of the Extraversion and Neuroticism items and of the three-factor structure of the nine Extraversion, nine Neuroticism and nine Lie scale items.     

Personality and differential susceptibility to hypnosis: further replication and sex differences.

Following the study of Gibson & Curran (1974), a further sample of 45 subjects were tested on the Eysenck Personality Inventory (EPI) and a slightly modified form of the Stanford Hypnotic Susceptibility Scale (SHSS) in precisely the same way. The results in this second sample were broadly the same as those obtained in the earlier study. Combining the two samples, it was found that the sex variable provided some interesting contrasts. The power of the lie scale of the EPI to predict hypnotic susceptibility observed earlier was found to be a significant effect only for males. While there was no significant difference between the sexes in terms of the means and S.D.S. of the extraversion (E) and neuroticism (N) scales, when the interaction of these scales was studied males and females differed significantly. The population from the two studies (n = 88) was analysed by means of polar coordinates in the manner suggested by Eysenck (1966) with regard to the E nad N scales. Esyenck's prediction as to hypnotic susceptibility was strikingly confirmed. These data are briefly discussed in terms of alternative approaches to hypnosis from the 'state' and the 'non-state' viewpoints.     

Individual differences in delayed heart-rate recovery following stress: The role of extraversion,neuroticism and emotional control

The aim of this study was to investigate the effects of individual differences on heart-rate reactivity and recovery following exposure to a laboratory stressor (performance on the Stroop task). The personality scales used were EPI Extraversion and Neuroticism and four subscales comprising the Emotion Control Questionnaire (ECQ). Contrary to predictions the EPI scales were unrelated to the physiological indices, but there were significant correlations between the Benign Control scale of the ECQ and heart rate reactivity and between the Rehearsal scale and heart-rate recovery.     

Personality, learning style and work performance

Just over two hundred telephone sales staff completed the Eysenck Personality Inventory (EPI) and Honey and Mumford's Learning Styles Questionnaire (LSQ). Extraversion was highly correlated both positively and negatively with three of the four LSQ measures. The lie scale from the EPI was also systematically correlated with the Activist and Reflector scales of the LSQ. Both the EPI and LSQ traits were modestly correlated with two criteria: ratings of Actual Performance and Development Potential. Regressions were used to determine the best predictors of the two ratings measures. Personality variables (extraversion, neuroticism) and certain learning styles (reflector, pragmatist) were statistically significant predictors of rated performance, though they accounted for less than 10% of the explained variance. The results concur with recent meta-analytical studies that show personality variables account for a small but important amount of variance in measures of work performance.     

Hierarchical structure of the Eysenck Personality Inventory in a large population sample: Goldberg’s trait-tier mapping procedure

The structure of the Eysenck Personality Inventory (EPI) is poorly understood, and applications have mostly been confined to the broad Neuroticism, Extraversion and Lie scales. Using a hierarchical factoring procedure, we mapped the sequential differentiation of EPI scales from broad, molar factors to more specific, molecular factors, in a UK population sample of over 6500 persons. Replicable facets at the lowest tier of Neuroticism included oversensitivity, mood lability, nervous tension and rumination. The lowest order set of replicable Extraversion facets consisted of social dynamism, sociotropy, haste, jocularity, communalism and impulsivity. The Lie scale consisted of an interpersonal virtue and a behavioral diligence facet. Users of the EPI may be well served in some circumstances by considering its broad Neuroticism, Extraversion and Lie scales as multifactorial, a feature that was explicitly incorporated into subsequent Eysenck inventories and is consistent with other hierarchical trait structures.     

To translate or to develop a measure? The case of a new Arabic measure of organizational justice

One of the most prominent and widely used self‐reporting scales for assessing organizational justice perceptions was developed by Colquitt (2001). This scale has been used internationally and has therefore been translated into several languages including Arabic. In a recent study, after conducting a careful review of organizational justice literature to ensure its relevance to Arabic culture, Alkhadher and Gadalreb ( 2016 ) developed a new Arabic measure of organizational justice (AMOJ) perceptions and found evidence of a four‐factor scale structure. The purpose of this study is to compare the Arabic version of Colquitt's measure of organizational justice (AVCMOJ) with the AMOJ in terms of predictive power using various outcome measures used by Colquitt (2001). The two scales were administered to 781 Kuwaiti employees (47.6% males) from the public sector. A multiple‐sample confirmatory factor analysis supports the four‐dimensional structure for both AVCMOJ and AMOJ measures. Cronbach's alpha obtained for subscales was found to range between 0.72 and 0.85. The predictive power of the three AMOJ dimensions (distributional, procedural, and informational) was found to be higher than that of the AVCMOJ. The results of the present study raise issues of scale development against the translation of well‐developed scales. Theoretical and practical implications of the results are discussed.     

Some EPI Reliability Estimates

The stability of the EPI over one month was estimated with 80 American university students, separately by sex (40 males, 40 females). The estimates for the extraversion-introversion (E-I), neuroticism (N) and lie scales ranged from 0.50 to 0.87. Reliability data (alternate-forms) from other sources were compared to the present results. It was concluded that the EPI has demonstrated generally high reliability for a personality measure, with reservations where the lie scale is concerned, and that the E-I scale alternate-forms, but not test-retest, reliability was generally lower than that for the N scale, suggesting that the alternate-forms are somewhat more equivalent for N than for E-I.     

An Inventory of Affective Tolerance

The two dimensions of personality, extraversion (E) and neuroticism (N) as measured by the Eysenck Personality Inventory (EPI), were tested for their social desirability response set and their independence. Results from a collegiate sample (N = 282) show that E and N scales were susceptible to social desirability response bias for males and females, respectively. This bias could not be overcome by eliminating Ss who reported higher scores on the lie scale included in the EPI. The dimensionality of the two scales for the male Ss is questionable.     

Conceptualization and measurement of millennial's social signaling and self‐signaling for socially responsible consumption

Social responsibility has rapidly gained popularity among consumers specifically among millennials born 1980 to 2000. Millennials are characterized by their willingness to get involved with social and political initiatives. Motivations for social responsibility are not completely unselfish in that individuals receive personal gain when providing support for others. This research proposes that socially responsible (SR) consumption has both social signaling and self‐signaling abilities. The scales for measuring millennial's social signaling and self‐signaling for SR consumption were developed to reflect the evolving nature of both social responsibility and the millennial generation. In‐depth interviews (n = 12) were used to generate scale items and an exploratory factor analysis was used to assess the dimensionality of the scales. Results were subjected to a confirmatory factor analysis that examined convergent and discriminant validity. Nomological validity testing was also performed. The social signaling for SR consumption scale was a one‐dimensional factor structure whereas the self‐signaling for SR consumption scale had two factors. These scales provide a tool for marketers and researchers to develop relevant SR initiatives aimed at millennials.     

A Multitrait-Multimethod Analysis of the MCMI-II Clinical Syndrome Scales

Multitrait-multimethod procedures and factor analyses were utilized to assess convergent/discriminant validity of the revised version of the Millon Clinical Multiaxial Inventory (MCMI-II) clinical syndrome scales and effects of item overlap on scale performance. Except for the Delusional Disorder Scale (PP), convergent validity was supported, but poor discriminant validity was found for the Alcohol Dependence (B) scale, Drug Dependence (T) scale, and Scale PP. Item overlap did not influence performance for many scales. In fact, results indicate that some scales, such as Bipolar: Manic (N), may perform better in overlapping form, whereas others, such as Somatoform (H) and Scales B and T, are most affected by item overlap. Factor structure was generally stable, regardless of whether overlapping or nonoverlapping scales were utilized. However, substance abuse/ dependence emerged as an independent factor when common item artifact was removed. Findings are discussed in terms of their implications for clinical practice and further research.

Adolescent coping scales: a critical psychometric review

Individual coping is identified as an important factor in relation to health and well-being. Although several coping scales have been developed, key terms of coping such as nature and a number of primary and secondary factors (dimensions) are obscure. Coping scales, such as those that have been developed through exploratory factor analysis (EFA), have been criticized for poor psychometric properties, yet the critique so far does not evaluate development of the scales against best test-theoretical practice. The present study reviews six adolescent coping scales against ten detailed psychometric criteria in relation to statistical choices throughout the process of scale development. All six scales measured poorly on several criteria. Best practice had not been followed throughout their development and they suffered serious psychometric limitations. These findings indicate that there still is empirical research to be pursued in search of latent constructs and possible dimensions of coping through the implementation of EFA.     

Dimensionality of the hospital anxiety and depression scale (HADS) in cardiac patients: comparison of Mokken scale analysis and factor analysis

The hospital anxiety and depression scale (HADS) measures anxiety and depressive symptoms and is widely used in clinical and nonclinical populations. However, there is some debate about the number of dimensions represented by the HADS. In a sample of 534 Dutch cardiac patients, this study examined (a) the dimensionality of the HADS using Mokken scale analysis and factor analysis and (b) the scale properties of the HADS. Mokken scale analysis and factor analysis suggested that three dimensions adequately capture the structure of the HADS. Of the three corresponding scales, two scales of five items each were found to be structurally sound and reliable. These scales covered the two key attributes of anxiety and (anhedonic) depression. The findings suggest that the HADS may be reduced to a 10-item questionnaire comprising two 5-item scales measuring anxiety and depressive symptoms.     

Victim-Blaming and Society-Blaming Scales for Social Problems

Until now, no general scales have been available for measuring victim or society blaming. This constraint has been an impediment to policymaking with regard to those who are affected by social problems. Four scales were constructed: stable victim-blaming scale, unstable victim-blaming scale, stable society-blaming scale, and unstable society-blaming scale. Based on the results of the preliminary exploratory factor analysis and the reliability coefficients, the unstable society-blaming scale was deleted from further analysis. Then, a confirmatory factor analysis using the LISREL 7 program was conducted to evaluate the parameter estimates of the scale items and examine the construct validity of the 3 scales. The scales were judged to have construct validity with satisfactory reliability.     

Another look at the psychometric properties of the Anxiety Control Questionnaire.

This study examined the psychometric properties of the Anxiety Control Questionnaire (AxCQ), a recently developed 30-item instrument intended to assess an individual's perceived level of control over anxiety related events. The sample consisted of 303 college students (189 females, 110 males, 4 no response). Although the scale is reported to have a two factor solution, results of an exploratory factor analysis in this sample indicated a three factor solution was more appropriate. Significant correlations were found between the three factor scales (r's ranged from 0.28 to 0.62). Internal consistency appeared good for the total AxCQ and for the factor scales derived from both the two and three factor models. There were no significant gender differences. We conclude that the psychometric properties of the scale look promising, but recommend that the factor structure of the AxCQ continue to be explored.     

THE DEVELOPMENT OF BEHAVIORAL OBSERVATION SCALES FOR APPRAISING THE PERFORMANCE OF FOREMEN

Behavioral observation scales (BOS) were developed for first line foremen. BOS are similar to behavioral expectation scales (BES) in that both are based on a job analysis procedure known as the critical incident technique. However, the BOS differ from BES in that, in developing BOS, (a) a group of individuals is observed and rated on a five-point scale as to the frequency with which they engage in the behavior described by each incident/statement, (b) a total score for each individual is determined by summing the observer's responses for each behavioral item, and (c) an item analysis (or factor analysis, depending upon the sample size) is conducted to select the most discriminating items. Those items with the highest correlations with the total score on a scale are retained to form one behavioral criterion or scale (BOS).     

Self, Other, Positive, and Negative Affect Scales of the Self-Confrontation Method: factorial structure and unidimensionality

In the self-confrontation method, the rows of a grid consist of valuations (i.e. summaries of important personal narratives), while the columns contain affects grouped into four scales (see title). These affects (varying from 16 to 30) are rated on a 0–5 scale of intensity, resulting in an affect profile for each valuation. Principal components analysis on the affect profiles of a client sample, using a list of 30 affects, yielded a 3-factor solution, with 2 unipolar and 1 bipolar factor, in accordance with the four scales. On the basis of this analysis, a list of 24 affects was derived with six affects per scale. This list was then applied to a student sample to cross-validate the results. Unidimensionality of the four scales was found at the level of single grids, and across both client and student samples. It was concluded that the four scales of the 24-affect list appeared to be psychometrically sound and optimally suited for use in research and practice.     

The relationship between oral character traits and extraversion/neuroticism

The present study was a factor-analytic study attempting to uncover the relationship between the psychoanalytic concept of oral traits and the personality dimensions of E and N. Two hundred and fifty-four Ss completed the Eysenck Personality Inventory (EPI) and thewritten form of the 19 oral scales designed by Goldman-Eisler. The data was subjected to factor analysis. It was found that five factors were necessary to account for the majority of the observed common variance. The extraction of five factors was contrary to the extraction of two factors in the Goldman-Eisler study. Path analysis, using multiple regression, was performed to find to what extent E and N influenced the 19 oral scales. It was found that 15 of the 19 scales were significantly causally influenced by E and N. Because there were discrepancies between the correlations in the present study and those reported by Goldman-Eisler, and discrepancies in the number of factors to emerge were found, it was decided to subject the original correlation matrix of the Goldman-Eisler study to re-analysis. The results of this re-analysis demonstrated serious mathematical flaws in Goldman-Eisler's results.     

THE ADAPTATION OF THE FAMILY ENVIRONMENT SCALE TO CHINESE CHILDREN AND ADOLESCENTS IN HONG KONG

Moos and Moos' (1986) Family Environment Scale (FES) was adapted to the Chinese children and adolescents in Hong Kong. The major sample included 1,174 subjects from three elementary schools and seven high schools. Two subscales, Expressiveness and Independence and a few items were deleted based on the psychometric analysis. The FES scale intercorrelations were consistent, and the factor pattern of the remaining eight scales was explicable in terms of the characteristics of the Chinese culture. Results also showed that middle class families in general had a more positive family social environment than the working class families.     

A validation study of goal orientations and self-efficacy scales

The aim of the current study was to investigate the validity and reliability of goal orientation and self-efficacy scales. The scales were administered to 264 university students (154 from engineering departments, 110 from business administration). Two samples were used. In the first sample, the original factor model was tested with confirmatory factor analysis. In the second sample, the Turkish versions of the scales were factor analyzed. Principal components analysis resulted in three components for the Goal Orientation scale: Learning goal orientation, Performance-prove goal orientation, and Performance-avoid goal orientation. The Self-efficacy scale had one factor as expected. Cronbach's alpha coefficients were satisfactory. The results did not fully support the use of current Turkish versions of the scales. Results of the studies are discussed along with the strengths and limitations of the study and suggestions for further development of the scales.
