Zuckerman-Kuhlman Personality Questionnaire: preliminary results of the Italian version

Cross-Border Reproductive Care: Psychological Distress in A Sample of Women Undergoing In Vitro Fertilization Treatment with and without Oocyte Donation

Background

Cross-border reproductive care (CBRC) refers to the movement of patients to foreign countries for fertility treatment. Limited evidence indicates that this phenomenon is associated with a risk of psychologi- cal distress, but few studies on the psychological impact of CBRC are currently available. The aim of this study was to compare the anxiety and depression levels of a group of cross-border patients with a local Spanish patient group, both of which underwent in vitro fertilization (IVF) treatment. We also sought to explore the clinical, sociodemographic and personality profiles of the CBRC group and local women.

Materials and Methods

This present cross-sectional study was conducted on 161 infertile females (71 CBRC patients and 90 local women) who were undergoing IVF treatment. The following questionnaires were used to collect data: Spielberger State Anxiety Inventory (STAI-S), the Beck Depression Inventory-II (BDI-II) and the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ). Sociodemographic, clinical, reproductive and CBRC variables were also recorded.

Results

CBRC patients, specifically CBRC oocyte recipients, showed higher levels of anxiety compared to lo- cal women. However, no significant differences in depression scores were found between both groups. Finally, when analysing personality, the Activity scale scores of the ZKPQ were found to be higher in CBRC oocyte recipients, which indicated a greater tendency for general activity and higher energy levels.

Conclusion

CBRC oocyte recipient women may have greater vulnerability to anxiety than local women prior to infertility treatment. Screening and psychological support protocols for anxiety in this population should be considered.

Multicultural Validation of the Zuckerman-Kuhlman-Aluja Personality Questionnaire Shortened Form (ZKA-PQ/SF) Across 18 Countries

The aim of this study was to assess the psychometric properties of the Zuckerman-Kuhlman-Aluja Personality Questionnaire shortened form (ZKA-PQ/SF) in 18 cultures and 13 languages of different African, American, Asian, and European cultures and languages. The results showed that the five-factor structure with 20 facets replicated well across cultures with a total congruence coefficient of .97. A confirmatory factor analysis (CFA) resulted in adequate fit indices for the five factors based on the comparative fit index (CFI), Tucker-Lewis index (TLI; >.90), and RMSEA (.031-.081). A series of CFA to assess measurement invariance across cultures resulted in adequate CFIs and TLIs for configural and metric invariance. However, factors did not show scalar invariance. Alpha internal consistencies of five factors ranged between .77 (Sensation Seeking) and .86 (Neuroticism). The average alpha of the 20 facets was .64 with a range from .43 (SS4) to .75 (AG1). Nevertheless, alpha reliabilities were lower in some facets and cultures, especially for Senegal and Togo. The average percentage of the variance explained based on the adjusted R² was 2.9%, 1.7%, and 5.1% for age, sex, and, cultures, respectively. Finally, multidimensional scaling suggested that geographically or culturally close cultures share mean profile similarities.

Psychometric Properties of the Chinese Shortened Version of the Zuckerman-Kuhlman Personality Questionnaire in a Sample of Adolescents and Young Adults

Introduction: The original 89-item Zuckerman–Kuhlman Personality Questionnaire (form III Revised, ZKPQ-III-R) is a widely accepted and used self-report measure for personality traits. This study assessed the reliability and construct validity of the Chinese short 46-item version of the ZKPQ-III-R in a sample of adolescents and young adults.

Methodology: A total of 1,019 Chinese adolescents and young adults completed the Chinese version of the original 89-item version ZKPQ-III-R and short 46-item version ZKPQ-III-R, self-report measures of depression, life satisfaction, and subjective health complaints (SHC), the Big Five personality traits, and a substance use risk profile. We explored the internal consistency of five dimensions of the short 46-item version ZKPQ-III-R and compared it with observations in previous studies of Chinese and other populations. The structure of the questionnaire was analyzed by confirmatory factor analysis and exploratory structural equation modeling.

Results: The short 46-item version ZKPQ-III-R had adequate internal reliability for all five dimensions, with Cronbach’s α coefficients of 0.63 to 0.84. The concurrent validity of the short 46-item version ZKPQ-III-R was supported by significant correlations with depression, life satisfaction, and SHC. The short 46-item version ZKPQ-III-R had better fit, similar reliability coefficients, and slightly better construct and convergent validity than the 89-item version.

Conclusion: The Chinese version of the 46-item ZKPQ-III-R presented reliability and validity in measuring personality in Chinese adolescents and young adults.

Circadian typology and the Alternative Five-Factor Model of personality

Two studies were carried out to explore the relationship between circadian typology and the Alternative Five-Factor Model of personality. In the first study, 379 participants (232 females) were administered the reduced version of the Morningness-Eveningness Questionnaire and the Zuckerman-Kuhlman Personality Questionnaire. Evening types reported higher impulsive sensation-seeking scores than morning and intermediate types, whereas morning types scored higher than evening types on activity factor. In the second study, the association between morningness and activity personality factor was verified through the objective-actigraphic monitoring of the rest-activity cycle. Actigraphy allowed us to operationalise both circadian typology, through the computing of midpoint of sleep (early values, expressed in hours and minutes, correspond to an advanced phase of the sleep/wake cycle), and activity factor by the means of motor activity recording. Fifty-one individuals (30 females) wore an actigraph on the nondominant wrist continuously for 1 week. A negative correlation was observed between midpoint of sleep and mean diurnal motor activity, demonstrating that an early phase of the sleep/wake cycle (i.e. morningness preference) was related to higher diurnal motor activity. Assessed both subjectively and objectively, the results of both studies highlight a significant relationship between morningness and activity personality factor.

Catalan and Hungarian validation of the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ)

The goal of this study was to examine the cross-cultural validity and reliability of the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) - a recently published instrument for assessing the Zuckerman's Alternative Five Factor Personality Model - in Catalan and Hungarian speaking populations. The samples consisted of 1,564 subjects from Catalonia and 1,647 from Hungary. Results showed a clear five-factor structure and acceptable alpha reliabilities of the ZKA-PQ in both countries. Facets alpha average was 80.35 and 74.10 for Catalans and Hungarians respectively. The factorial congruency coefficients indicated that both structures were equivalent, with a global value of .97. However, the robust structure obtained with EFA yielded poor fit indices in the subsequent CFA. Altogether, the psychometric findings were similar to those obtained in the original validation study carried out in Spanish and English populations. Main country differences were found only in Neuroticism factor, with Hungarians scoring significantly lower that Catalans. Nevertheless, country, sex and age explained only 18.6 % of Neuroticism variance (adjusted R squared = .186). Country differences had only medium effect size [F(1, 3188) = 292, p < .001, η2 = .084 1 ].

Psychometric Properties of the Romanian Version of the Zuckerman-Kuhlman Personality Questionnaire

This research investigated the psychometric properties and the convergent and divergent validity of the Romanian version of the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ) at the factor-level. The ZKPQ assesses the five basic factors of Zuckerman’s alternative five-factor model (AFFM). Study 1 (n = 449) assessed the psychometric properties of the Romanian version of the ZKPQ and verified its factorial structure. The factors reliability ranged from .69 to .88, and gender differences were similar to those found in the Spanish, French, and Chinese samples. Exploratory factor analysis supported the replicability of the original five-factor structure, and correlations between the scales showed that the five basic factors of the AFFM are relatively independent. Study 2 (n = 238) verified the convergent and divergent validity of the Romanian version of the ZKPQ, by testing its links with DECAS, a personality inventory based on the five-factor model, developed and well-validated on the Romanian population. The results showed good convergent and divergent validity, with all identified correlations supporting the correspondence between the two personality models. Overall, the present findings showed that the Romanian version of the ZKPQ is a valid tool for assessing personality traits according to the AFFM.

Consensual validity parameters of the Zuckerman-Kuhlman personality questionnaire: evidence from self-reports and spouse reports

One way of validating questionnaire responses is correlating them with ratings made by external assessors who know the ratee well: This is known as consensual validity. In this study, we assessed the consensual validity of the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ; Zuckerman, 2002; Zuckerman, Kuhlman, Joireman, Teta, & Kraft, 1993). A multitrait-multimethod matrix of self-reported and spouse reported personality ratings was used to establish convergent and discriminant validity by means of Campbell and Fiske's (1959) evaluative criteria. Self-reports of 86 men and 85 women were correlated with their spouses' reports. Intraclass correlations ranged from .47 to .63 for the 5 dimensions, providing strong evidence of convergent and discriminant validity. The results obtained favor the use of the ZKPQ as a valid self-report measure of personality traits.
