Nonverbal assessment of the Big Five personality factors

The Nonverbal Personality Questionnaire (NPQ) is an experimental, structured, nonverbal measure of 16 personality traits. Its items lack verbal content and, therefore, the inventory is useful for cross‐cultural research. Our goal is this research was to select a subset of the NPQ items to form a new nonverbal questionnaire based on the Five‐Factor Model of personality. We describe the construction of the Five‐Factor Nonverbal Personality Questionnaire (FF‐NPQ), and present data on its psychometric properties. These data include scale internal consistencies, intercorrelations, convergences with verbal measures of the Big Five factors, discriminant validity correlations, correlations with peer ratings, and ability to predict socially important behaviour criteria such as smoking and alcohol consumption. In a second study, we report on the psychometric properties of the FF‐NPQ in an independent sample of respondents from seven different countries. The utility of the new nonverbal inventory for cross‐cultural research is discussed. Copyright © 2001 John Wiley & Sons, Ltd.     

Psychometric evaluation on the Japanese adaptation of the Aggression Questionnaire.

The psychometric properties of a Japanese translation of the Aggression Questionnaire (Buss & Perry, 1992, Journal of Personality and Social Psychology, 63, 452-459) were investigated. Factor analysis of the responses of 425 Japanese participants generally supported the four-factor model. The factors were Physical Aggression, Verbal Aggression, Anger and Hostility. The internal consistencies of the four subscales were adequate. The results suggested that the Japanese version of the Aggression Questionnaire met psychometric standards and appears to be a promising measure of aggression. However, the Japanese version may be improved if two reversed scored items are removed from the scale. The cross-cultural difference in responses between negatively-oriented and affirmatively-oriented questions was discussed.     

Psychopathy and the personality dimensions of psychoticism,extraversion and neuroticism

The Eysenck Personality Questionnaire (EPQ) was administered to 173 male prison inmates for whom reliable assessments of psychopathy were available. Psychopathy was significantly correlated with the Psychoticism (P) scale (r = 0.16) and the Lie scale (r = 0.14), but not with the Extraversion (E) or Neuroticism (N) scales. Zone (octant) analysis indicated that psychopathy was not associated with any particular combination of P, E and N scores. Additional analyses, based on the discriminant function procedure described in the EPQ manual, indicated that inmates with high assessments of psychopathy were significantly less psychiatrically abnormal, in the EPQ sense, than were those with low assessments of psychopathy. A series of comparisons was also made between the P scale and a 22-item psychopathy checklist. The P scale was significantly correlated with six of the items, and with factors 1 (r = 0.30) and 4 (r = 0.19) that emerged from a principal components analysis of the checklist. Factor 1 is related to an impulsive, unstable lifestyle with no long-term commitments and factor 4 to the early appearance of antisocial behavior. It is argued that the P scale reflects the criminal, antisocial aspects of psychopathy and that the results probably have no direct implications for the suggestion that psychopathy and psychoticism are related in some fundamental way. A canonical analysis indicated that some interesting relations may exist between the EPQ variables and the psychopathy factors.     

What I Think and Feel: A Revised Measure of Children's Manifest Anxiety

The 1956 adaptation for children of Taylor's Manifest Anxiety Scale, the Children's Manifest Anxiety Scale, was revised to meet current psychometric standards. A 73-item revision draft was administered to 329 school children from grades 1 to 12. Based on item-analysis criteria for r _bis .4 and .30 p .70, 28 anxiety items were retained along with 9 of the original 11 Lie scale items. A cross-validation sample of 167 children from grades 2, 5, 9, 10, and 11 produced a KR₂₀ reliability estimate of .85. Anxiety scores did not differ across grade or race. Females scored significantly higher than males. For the Lie scale, significant differences appeared by grade and race. No sex differences were obtained on the Lie scale. The resulting scale appears useful for children in grades 1 to 12 and may aid in future studies of anxiety as well as assisting the clinician in the understanding of individual children.     

Reliability and factorial structure of the Chinese version of the State-Trait Anxiety Inventory

The Chinese version of the State-Trait Anxiety Inventory (STAI) was administered to 2150 Chinese secondary-school students. Reliability data revealed that the A-State and A-Trait scales had a high internal consistency, and high item-total correlations were found for most of the items under each scale. Factor analytic data showed that while two factors were abstracted from the A-Trait scale (Anxiety Present and Anxiety Absent), two (Anxiety Present and Anxiety Absent) or three (Anxiety Present, Calmness, and Happiness) factors were abstracted from the A-State scale. By randomly splitting the total sample into two subsamples, factors extracted from the first two factor-solutions could be reproduced reliably and high coefficients of congruence were found. These findings generally suggest that the Chinese A-State and A-Trait scales possess acceptable psychometric properties and the factor analytic data tend to support Spielberger's conception of the multidimensional nature of the A-State and A-Trait scales.This work was supported by UPGC Grant CPAS/714.

Refinement of the MMPI-2 F(p) scale is not necessary: a response to Gass and Luis

Gass and Luis (2001) reported that four MMPI-2 Lie scale items contained on the F(p) scale do not measure symptom exaggeration but measure defensiveness. They hold that elimination of the four Lie scale items improves the utility of the F(p) scale in the identification of exaggeration in VA samples. To directly address the assertion that removal of the L scale items from the F(p) scale enhances the predictive validity of F(p), data derived from a previously published study where 74 psychiatric inpatients were asked to retake the MMPI-2 and either feign psychopathology or respond in an honest manner were reanalyzed. The intact F(p) scale demonstrated a stronger correlation with group membership, increased incremental validity, and superior classification rates compared with the F(p) scale without the 4 Lie scale items. Consequently, the F(p) refinement recommended by Gass and Luis is unnecessary.     

The State Adult Attachment Measure (SAAM): A construct and incremental validity study

Recent studies have shown that relationship experiences and contextual factors may influence attachment security, anxiety, and avoidance. In the present study, we investigated the psychometric properties of the Italian translation of the State Adult Attachment Measure (SAAM), a personality scale aimed to assess temporary variations in adult attachment styles (Gillath, Hart, Noftle, & Stockdale, 2009). Four hundred Italian participants took a set of standardized self-report attachment scales and other measures of subjective wellbeing and mental-health. Confirmatory Factor Analysis showed an acceptable fit between the SAAM three-factor model and the data, confirming the hypothesized measurement model for security, anxiety, and avoidance. SAAM subscales also attained high internal consistency reliability, were properly related to mainstream attachment style scales, and had incremental validity in predicting psychological well-being and mental health. The Italian SAAM translation is indeed a reliable and valid measure, showing promise as a clinical assessment of short-term changes in attachment states, even in non-English cultural context.     

Innovations in Assessing ADHD: Development, Psychometric Properties, and Factor Structure of the ADHD Symptoms Rating Scale (ADHD-SRS)

This research involved the development of a behavior rating scale designed to measure ADHD and the investigation of the scale's psychometric properties and factor structure. This scale, the ADHD Symptoms Rating Scale (ADHD-SRS), was developed for the assessment of ADHD in the school-age (K–12) population. Participants were 1006 children and adolescents (in grades K–12) who were rated by their parents and/or teachers. The results indicate that the ADHD-SRS possesses strong internal consistency reliability and test–retest reliability and moderate cross-informant reliability. The data also suggest that the ADHD-SRS has strong content validity. Convergent validity of this instrument was also high, as demonstrated by correlations with three previously validated behavior rating scales. Significant age and gender differences in ADHD symptoms were found with both the parent and teacher respondent populations. Finally, the factor analysis of the ADHD-SRS suggested a two factor oblique rotation as the best fit for both the parent and the teacher data. After a visual inspection of the items which loaded on each factor, Factor 1 was named Hyperactive-Impulsive and Factor 2 was named Inattention. These two factors, along with the items which loaded on each factor, appear to be remarkably similar to the two categories listed in the DSM-IV for ADHD. Directions for future research, as well as clinical implications and limitations of the research are discussed.     

A psychometric investigation of the Eysenck Personality Questionnaire.

The Eysenck Personality Questionnaire was administered to 139 females and 123 males. Scale statistics were obtained and hierachial factor analyses were performed. The P scale was found to have low internal consistency reliabilities and to covary with the L scale in the female subsample. Factor analyses showed recovery of E scale items in a secondary factor, Social Extraversion, without an impulsivity primary factor. No P and N dimensions recovered; rather components of each scale interrelated in two meaningful dimensions at the tertiary level.     

National differences in personality: India and England

This study reports comparisons between results on the Eysenck Personality Questionnaire (EPQ) obtained from 558 male and 636 female Indian Ss; the comparison group of the original standardized English Sample (Eysenck and Eysenck, 1975). Factor analysis of item correlations showed close correspondence between the factors extracted in the two samples, with indices of factor comparisons being well in excess of 0.97. The reliabilities in the Indian sample were only marginally lower than in the original English standardization group. Some items from the original EPQ did not load on the hypothesized factors; they were substituted by the extra items contained in the 101-item version of the EPQ used in India. The Indian data showed no sex differences with respect to extraversion; females were found to score higher on the Neuroticism and also slightly higher on the Lie scale than the males. The Lie scores for both males and females being quite high suggests a consistent trait of conformity in operation. It was concluded that the organization of personality in India is sufficiently similar to that in England to make national comparisons feasible since identical dimensions underlie the personalities of Indian and English Ss.     

Personality for free: Psychometric properties of a public domain Australian measure of the five‐factor model

Fifty items from Goldberg's International Personality Item Pool were compiled to form a public‐domain measure of personality, the Australian Personality Inventory (API). Data from a random community sample (N = 7615) and a university‐based sample (N = 271) were used to explore psychometric properties of this 50‐item measure of the five‐factor model of personality (FFM). In both samples, internal reliabilities were adequate. In the university‐based sample an appropriate pattern of convergent and divergent relationship was found between scale scores and domain scores from the NEO Five‐Factor Inventory. After adjusting for an apparent response set (mean response across items), exploratory factor analyses clearly retrieved the FFM in both samples. It is provisionally concluded that raw scale scores from the API provide reliable estimates of the FFM, but adjustment for mean response across the 50 items might clarify the five‐factor structure, especially in less educated samples.     

Internet addiction,self-esteem and the validation of the Italian version of the Internet Related Experiences Questionnaire

IntroductionThe continued progression of the digital age raises the question of Internet and social media abuse among adolescents and of the need for more specific assessment instruments to measure the phenomenon.ObjectiveThe purpose of the current study was to explore the role of intrapersonal and interpersonal factors influencing Internet addiction, as well as to evaluate the psychometric properties of the Internet Related Experiences Questionnaire (IREQ-I) in relation to a sample of Italian adolescents.MethodTwo studies were designed. In study 1, a school-based sample of 838 Italian adolescents was recruited to test the psychometric properties of the IREQ-I by using a robust Confirmatory Factor Analysis (CFA). In study 2, a total of 438 Italian adolescents were recruited to investigate the concurrent validity of the instrument.ResultsWe found that intrapersonal rather than interpersonal factors were associated with Internet abuse. The final version of the IREQ-I showed a good level of fit and the bi-factorial solution was consistent with the previous findings.ConclusionThe results of this study suggest that the IREQ-I is a valuable bifactorial instrument for measuring Internet abuse, including both intrapersonal and interpersonal factors as theoretically relevant constructs.     

Cross-national generalizability of patterns of parental rearing behaviour: Invariance of EMBU dimensional representations of healthy subjects from Australia,Denmark, Hungary,Italy and The Netherlands

A psychometric study was carried out on Australian, Danish, Hungarian, Italian and Dutch non-patient samples examining cross-national invariance characteristics of dimensions of perceived parental rearing behaviour and attitudes as measured by the EMBU. Of the four primary factors identified previously with Dutch Ss, namely Rejection, Emotional Warmth, Overprotection and Favouring Subject, the first three were retrieved in a similar form in the Australian, Danish and Italian healthy Ss. Less satisfactory findings emerged in the Hungarian sample. Further analyses examining metric equivalence of the scales and the strength of the factors for each group indicated that it would be warranted to carry out future pattern and level comparisons between groups from the respective countries (except Hungary) on the three factors evidencing cross-national constancy. Higher order factor analyses of the corresponding scales produced identical two-factor compositions (Care and Protection) in the Australian, Danish and Italian groups when compared to the factorial composition of EMBU scales of their Dutch counterparts, which further supported this conclusion. It was proposed to either rephrase or omit and replace the unsuitable Hungarian EMBU items by alternative items to be tried out in the next round of data gathering and their psychometric evaluation.     

The Italian version of the Inventory of Interpersonal Problems Personality Disorders Scales (IIP-47): psychometric properties and clinical usefulness as a screening measure

The Inventory of Interpersonal Problems-47 (IIP-47) is a brief and valid self-report measure for screening Personality Disorders (PDs). This study examined internal consistency, factor structure, criterion validity, temporal stability, and operating characteristics of the Italian version of the IIP-47 in two independent samples: PD subjects (n = 120) and nonclinical subjects (n = 475). Alpha coefficients ranged from .70 to .90. Multiple-Group Confirmatory Factor Analyses showed that the five-correlated-factor model reported in literature had the highest measurement invariance across the two groups. Criterion validity was supported by correlations among IIP-47 scale scores and scores on established measures of personality dimensions and pathology. Test-retest indices ranged from .71 to .95. PD subjects scored significantly higher than nonclinical subjects on all IIP-47 scales and cut-off scores for different levels of specificity and sensibility are reported. It is concluded that the psychometric properties of the original IIP-47 were preserved in its Italian version.     

The Need for Recovery scale: Adaptation to the Italian context

IntroductionNeed for Recovery scale is one of the main scales used to assess work-induced fatigue and quality of workers’ recovery time. In fact, need for recovery is considered relevant as a precursor of prolonged fatigue or psychological distress, an indicator of work stress, and a mediating or moderating characteristic in the etiology of work-related health problems, sick leave and work disability.ObjectiveThe purpose of the present study is to translate the Need for Recovery scale into Italian, and to adapt it to Italian culture; until now there has been no comparable valid instrument made for the Italian language that measures the need for recovery of employees. The stability and internal consistency of the scale will be assessed among Italian workers.MethodFor cross-cultural adaptation, a translation/back-translation method integrated with expert committee review and pre-testing was applied. Three hundred and seventy-eight Italian workers filled out the scale.ResultsThe psychometric properties proved to be good, both in terms of scale homogeneity and internal consistency, for the total sample and for subgroups of Italian employees in terms of gender, age and educational level. Exploratory factor analysis suggested a single factor solution with 44% of the variance explained.ConclusionsResults are encouraging for the possibility of using the Need for Recovery scale as a quick and adequate scale to measure early symptoms of work-induced fatigue and quality of Italian workers’ recovery time.     

Weight Bias Internalization Scale Discriminates Obese and Overweight Patients with Different Severity Levels of Depression: the Italian Version of the WBIS

We have investigated the psychometric properties of the Italian version of the weight bias internalization scale (WBIS) in overweight and obese patients who were attending weight loss programs. Participants were 386 overweight and obese patients admitted in two medical centers specializing in the treatment of obesity. All the patients were administered the WBIS, and measures of binge eating, depression, self-esteem, and body dissatisfaction. Confirmatory factor analysis failed to confirm the fit of the original 11-item unidimensional model. Item analysis and exploratory factor analysis indicated that 9 items included in the original measure (the items 1 and 9 were excluded because low item-total correlations) formed a reliable unidimensional measure of internalized weight bias (WBIS-9). The WBIS-9 was significantly correlated with convergent measures and was able to categorize individuals with different severity levels of depression (sensitivity of 0.72 and specificity of 0.70). The WBIS-9 may be useful in clinical practice to discriminate patients with more severe psychopathology, comorbid disordered eating patterns, and risk for poor outcomes.     

Development and psychometric evaluation of a post exercise exhaustion scale utilising the Rasch measurement model

ObjectivesThe objective of this study to report on the development and psychometric analysis of a scale to measure post exercise exhaustion.DesignThis study utilised the Rasch measurement model for the psychometric analysis of a new scale aimed at measuring acute onset exhaustion in athletes.MethodAn extensive literature review, feedback from athletes and an expert panel from educators in psychology, sports science and exercise physiology provided feedback on the scale, providing evidence of content validity. A final survey, consisting of the 25 items and completed by three hundred and seventy-nine athletes (Sport: 187 tri-athletes and 192 cyclists; gender: 211 males, and 168 females; age: 18–25 [31], 26–35 [114], 36–45 [120], and 46+ [114]), was submitted to Rasch analysis.ResultsAfter amendments a final 14 item scale provided internally consistent and reliable measures of exhaustion for participants. The items of the final scale have good fit, and the scale has high PSI providing statistical evidence of reliability. The scale could benefit from items dealing with mid-range levels of exhaustion. The correlational association between the new scale and a similar scale was positive and significant correlation adding to the evidence of the validity of the new scale.ConclusionsThe scale appears to be a valuable tool for the assessment of exercise-induced acute onset exhaustion and may be an attractive option for researchers, clinicians, and coaches seeking to measure the levels of exhaustion in individuals. In addition to its valid theoretical structure and sound psychometric properties, the scale has advantages over other exhaustion or fatigue scales as it is not disease-specific.     

Psychometric properties of the Dutch version of the Automatic Thoughts Questionnaire - Positive (ATQ - P)

The role of positive cognitions in psychopathology is increasingly recognized. Several measures of this construct have been devised. The most well-known instrument to measure positive self-referent thoughts is the Automatic Thoughts Questionnaire - Positive (ATQ - P). The present study explored the psychometric properties of the Dutch version of this questionnaire. Data were derived from 257 bereaved adults. Confirmatory Factor Analysis showed that an oblique 5-factor model with items pertaining to Positive Daily Functioning, Positive Self-Evaluation, Other's Evaluation of Self, Positive Future Expectations, and Positive Social Functioning fit the data well. This model was a slight modification of the 4-factor model originally proposed by the developers of the ATQ - P, in which items pertaining to Positive Social Functioning were part of the factor Positive Daily Functioning. The internal consistency and the short-term temporal stability of the ATQ - P were found to be satisfactory. In addition, the 5 factors as well as the summed total score of the ATQ - P showed adequate discriminative, construct, divergent and convergent validity. In sum, the present study indicates that the Dutch ATQ - P is an effective measure of positive automatic cognitions.
