Personality assessment without borders: adaptation of the MMPI-2 across cultures

Adjusting Bilingual Ratings by Retest Reliability Improves Estimation of Translation Quality

The quality of cross-language scale translations is often explored by having bilingual participants complete the scale in both languages and then correlating their scores. However, low cross-language correlations can be observed due to score unreliability rather than due to poor scale translation. McCrae, Yik, Trapnell, Bond, and Paulhus suggested that a better indicator of translation quality can be formed by dividing the raw cross-language correlation by the same-language retest correlations over a similar measurement interval. Here, we illustrate how this method can be extended to evaluate the translation quality of individual items. We translated the English version of the Inventory of Individual Differences in the Lexicon (IIDL) into Chinese, and within a single survey session participants either completed the instrument either in both languages ( N = 151 bilingual participants) or twice in Chinese ( N = 94) or in English ( N = 82). Finally, additional bilingual participants ( N = 46) rated the perceived translation quality of each item. Variation in the cross-language correlations across items predicted perceived translation quality, however, adjusting for same-language retest correlations resulted in significantly stronger indicators of perceived translation quality. The present study thus indicates the validity of McCrae et al.’s general method, and demonstrates that it can be extended to designs where all participants complete a single test session and can be applied to evaluate the quality of translations of single items.

A pilot study on the Chinese Minnesota Multiphasic Personality Inventory-2 in detecting feigned mental disorders: Simulators classified by using the Structured Interview of Reported Symptoms

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is often used in forensic psychological/psychiatric assessment. This was a pilot study on the utility of the Chinese MMPI-2 in detecting feigned mental disorders. The sample consisted of 194 university students who were either simulators (informed or uninformed) or controls. All the participants were administered the Chinese MMPI-2 and the Structured Interview of Reported Symptoms-2 (SIRS-2). The results of the SIRS-2 were utilized to classify the participants into the feigning or control groups. The effectiveness of eight detection indices was investigated by using item analysis, multivariate analysis of covariance (MANCOVA), and receiver operating characteristic (ROC) analysis. Results indicated that informed-simulating participants with prior knowledge of mental disorders did not perform better in avoiding feigning detection than uninformed-simulating participants. In addition, the eight detection indices of the Chinese MMPI-2 were effective in discriminating participants in the feigning and control groups, and the best cut-off scores of three of the indices were higher than those obtained from the studies using the English MMPI-2. Thus, in this sample of university students, the utility of the Chinese MMPI-2 in detecting feigned mental disorders was tentatively supported, and the Chinese Infrequency Scale (ICH), a scale developed specifically for the Chinese MMPI-2, was also supported as a valid scale for validity checking.

Psychometric Evaluation of the MMPI-2/MMPI-2-RF Restructured Clinical Scales in an Israeli Sample

The current study cross-culturally evaluated the psychometric properties of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2)/MMPI-2-Restructured Form Restructured Clinical (RC) Scales in psychiatric settings in Israel with a sample of 100 men and 133 women. Participants were administered the MMPI-2 and were rated by their therapists on a 188-item Patient Description Form. Results indicated that in most instances the RC Scales demonstrated equivalent or better internal consistencies and improved intercorrelation patterns relative to their clinical counterparts. Furthermore, external analyses revealed comparable or improved convergent validity (with the exceptions of Antisocial Behavior [RC4] and Ideas of Persecution [RC6] among men), and mostly greater discriminant validity. Overall, the findings indicate that consistent with previous findings, the RC Scales generally exhibit comparable to improved psychometric properties over the Clinical Scales. Implications of the results, limitations, and recommendations for future research are discussed.

Using cognitive interviewing for the semantic enhancement of multilingual versions of personality questionnaires

We discuss the use of cognitive interviewing with bilinguals as an integral part of cross-cultural adaptation of personality questionnaires. The aim is to maximize semantic equivalence to increase the likelihood of items maintaining the intended structure and meaning in the target language. We refer to this part of adaptation as semantic enhancement, and integrate cognitive interviewing within it as a tool for scrutinizing translations, the connotative meaning, and the psychological impact of items across languages. During the adaptation of a work-based personality questionnaire from English to Arabic, Chinese (Mandarin), and Spanish, we cognitively interviewed 12 bilingual participants about 136 items in different languages (17% of all items), of which 67 were changed. A content analysis categorizing the reasons for amending items elicited 11 errors that affect 2 identified forms of semantic equivalence. We provide the resultant coding scheme as a framework for designing cognitive interviewing protocols and propose a procedure for implementing them. We discuss implications for theory and practice.

Psychometric properties of the Polish adaptation of the Infant Behavior Questionnaire—Revised (IBQ-R)

This paper presents the psychometric properties of the Polish version of the Infant Behavior Questionnaire—Revised (IBQ-R). A group of 396 pairs of parents was studied, and a 3-factor structure of IBQ-R emerged with differences comparing to the original U.S. sample and a prior replication Russian sample. Analyses demonstrated satisfactory internal consistency and high consistency rating between both parents' scores. Additionally, a comparison of the scores of IBQ-R scales between Polish and previously reported U.S. data was made, showing that Polish infants scored higher on negative affectivity scales and lower on surgency/extraversion and orientation/regulation scales.

MMPI-II personality profiles of patients with psychogenic nonepileptic seizures

This comparative study explored whether psychogenic nonepileptic seizures (PNES) are a unique disorder with distinctive personality characteristics or (seen from the personality profile) PNES are allied with the domain of a general functional somatic symptom and syndrome (FSSS). We compared the Minnesota Multiphasic Personality Inventory 2 (MMPI-2) results for 41 patients with newly diagnosed PNES and 43 patients with newly diagnosed insomnia. There were no statistically significant quantitative scoring differences on the main clinical scales, indicating that there is no substantial difference in "personality makeup" between the two groups with a FSSS. Additional subscale analysis indicated that patients with PNES reported significantly more somatic complaints (Hysteria 4) and bizarre sensory experiences (Schizophrenia 6). Further profile analysis revealed that the personality pattern of patients with PNES was characterized by a strong tendency toward "conversion V, a lack of control pattern and less excessive worries" as compared with patients with insomnia. Patients with PNES are characterized by a stronger tendency toward somatization and externalization, which has treatment implications.

Two languages, two personalities? Examining language effects on the expression of personality in a bilingual context

The issue of whether personality changes as a function of language is controversial. The present research tested the cultural accommodation hypothesis by examining the impact of language use on personality as perceived by the self and by others. In Study 1, Hong Kong Chinese-English bilinguals responded to personality inventories in Chinese or English on perceived traits for themselves, typical native speakers of Chinese, and typical native speakers of English. Study 2 adopted a repeated measures design and collected data at three time points from written measures and actual conversations to examine whether bilinguals exhibited different patterns of personality, each associated with one of their two languages and the ethnicity of their interlocutors. Self-reports and behavioral observations confirmed the effects of perceived cultural norms, language priming, and interlocutor ethnicity on various personality dimensions. It is suggested that use of a second language accesses the perceived cultural norms of the group most associated with that language, especially its prototypic trait profiles, thus activating behavioral expressions of personality that are appropriate in the corresponding linguistic-social context.

Assessment of autism in community settings: discrepancies in classification

Review of 78 evaluations for 29 young children examined practices used in assessment of autism spectrum disorders in three settings: public schools, developmental disabilities eligibility determinations, and our hospital-based early childhood mental health program. While similar rates of classification of autism spectrum disorders were found across sites, the rate of agreement by different evaluators for individual children was only 45%. Further, most community evaluators did not follow best practice guidelines nor use autism diagnostic tools with established psychometric properties. In this sample of primarily Latino, Spanish-speaking children, most community evaluators did not document assessment of the child in their native language, nor address the impact of language in their assessments.

When No Bilingual Examiner Is Available

Reliable and valid assessment of individuals who are English language learners (ELL) has presented a dilemma to psychologists, and school psychologists in particular, as it is complicated by the small number of professionals qualified to serve as bilingual examiners. Some psychologists use ancillary examiners during testing when no bilingual psychologist is available to conduct the evaluation, and both the process and the impact of using ancillary examiners need further investigation. This study examined the performance of students under two testing conditions, one with a monolingual psychologist and an ancillary examiner, and another with a bilingual psychologist without an ancillary examiner. Students tested in English, with English as their dominant language, consistently performed better than those students tested in Spanish on sub-tests that required detailed verbal responses. Results also indicated that evaluation format may have an effect on student performance and can lead to different levels of performance.

Anticonvulsant treatments of dysphoric mania: a trial of gabapentin, lamotrigine and carbamazepine in Iran

The treatment of dysphoric mania is challenging given the need to treat symptoms of both depression and mania simultaneously without provoking any clinical exacerbation. The newer antiepileptic drugs such as gabapentin, lamotrogine, and carbamazepine are often used as adjuncts to either lithium or valproic acid in the treatment of bipolar disorder. We decided to undertake a monotherapy trial because previous evidence suggested mixed states may be more responsive to anticonvulsants than more traditional antimanic agents. 51 patients with a DSM IV diagnosis of dysphoric mania were randomized to three groups comprising gapbapentin, lamotrogine or carbamazepine and followed for 8 weeks. Psychiatric diagnosis was verified by the structural clinical interview for the DSM-IV (SCID). The MMPI-2 in full was used to assess symptoms at baseline and 8 weeks. All three groups showed significant changes in MMPI-2 scores for depression and mania subscales. Gabapentin showed the greatest change in depression symptom improvement relative to lamotrogine and carbamazepine, respectively. Although manic symptoms improved overall, here were no differences between groups in the degree of manic symptom improvement.

MMPI–2 Profiles of Women With Eating Disorders in a Dutch Day Treatment Sample

In this study, we examined the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) profiles of 324 Dutch patients with eating disorders at an eating disorder day treatment program. We studied the MMPI-2 profiles in 5 diagnostic eating disorder groups. All diagnostic subgroups showed high mean elevations of the T scores on the same 6 or 7 scales. Remarkable similarities existed between the mean profile configurations. The MMPI-2 distinguished especially in that patients with restricting anorexia nervosa scored lower on one Validity scale (F), two Clinical scales (1 and 2) and several Supplementary and Content scales of the MMPI-2 compared to the other groups. Only on the validity Scale L did they score higher. The MMPI-2 also distinguished patients with the bulimia nervosa purging type who scored higher on Scale 9 and different on several Content and Supplementary scales. We discuss results with regard to other studies of MMPI (Hathaway & McKinley, 1983) and MMPI-2 profiles of women with anorexia nervosa, bulimia nervosa, and eating disorder not otherwise specified in inpatient and outpatient settings.

MMPI-2 profiles of Australian and Singaporean psychiatric patients

The use of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) as a useful measure of psychopathology has been shown in extensive studies. However, there is limited research on the ability of the MMPI-2 to measure differences across diverse cultures. This study aims to extend the research on Caucasian-Chinese MMPI profiles to the countries of Singapore and Australia by examining cross-nation variations. Participants were recruited from psychiatric outpatient clinics and consisted of 70 and 107 patients from Singapore and Australia, respectively. It was predicted that similarities across the two cultures would be observable, with differences reflected on specific scales. The overall findings indicate that MMPI-2 profile comparisons are comparable between Australian and Singaporean subjects, with considerably more similarities than differences. However, there are significant differences on specific MMPI-2 subscales including the lie, hypochondriasis, Addiction Potential Scale, overcontrolled hostility, fears, health concerns and negative treatment indicators. It is suggested that the differences are a reflection of cultural and ethnic distinctions specific to each country, whereas the commonalities between the two nations indicate comparable overall profiles.
