Narcissism as a psychological construct has had a contentious past both in its conceptualization and measurement. There is an emerging consensus that narcissism consists of grandiose and vulnerable subtypes, which share a common core. In the present research (N = 1002), we constructed a new measure of unified narcissism that reflects these contemporary understandings using items from the most widely used measures of grandiose and vulnerable narcissism: the Narcissistic Personality Inventory (NPI; Raskin & Terry, 1988, https://doi.org/10.1037/0022-3514.54.5.890), and the Pathological Narcissism Inventory (PNI; Pincus et al., 2009, https://doi-org/10.1037/a0016530). We used classical test theory and item response theory approaches to devise a 29-item Unified Narcissism Scale. The scale showed good internal consistency, and convergent and discriminant validity, and showed evidence of measurement invariance between men and women. This research gave strong support for the structure, reliability, and validity of the unified measure, which offers a promising avenue for further enhancing our knowledge of narcissism.

The factorial structure, reliability, convergent and discriminant validity, as well as factorial invariance of the 10-item Connor-Davidson Resilience Scale (CD-RISC-10) were determined. The sample was composed of 330 students (174 medical students and 156 psychology students) with a mean age of 20.20 years (SD = 2.33). The results obtained con-firm the unidimensional structure of the scale (χ2/df = 3.06, GFI = .93, CFI = .92, NFI = .90, TLI = .92, RMSEA = .08, and SRMR = .04), the factorial in-variance with respect to career, and good internal consistency (ω = .85 and α = .85). A statistically significant difference in the level of resilience bet-ween medical students (M = 20.64, SD = 4.48) and psychology students (M = 20.27, SD = 4.51) was found [t(281) = 2.65, p = .009, d = .20]. Evidence of convergent and discriminant validity of CD-RISC-10 with happiness and perceived stress was obtai-ned. It is concluded that CD-RISC-10 shows adequate psychometric properties to measure resi-lience in Mexican university students

Five Phases

The Faceted Inventory of the Five-Factor Model (FI-FFM) is a comprehensive hierarchical measure of personality. The FI-FFM was created across five phases of scale development. It includes five facets apiece for neuroticism, extraversion, and conscientiousness; four facets within agreeableness; and three facets for openness. We present reliability and validity data obtained from three samples. The FI-FFM scales are internally consistent and highly stable over 2 weeks (retest rs ranged from .64 to .82, median r = .77). They show strong convergent and discriminant validity vis-à-vis the NEO, the Big Five Inventory, and the Personality Inventory for DSM-5. Moreover, self-ratings on the scales show moderate to strong agreement with corresponding ratings made by informants ( rs ranged from .26 to .66, median r = .42). Finally, in joint analyses with the NEO Personality Inventory–3, the FI-FFM neuroticism facet scales display significant incremental validity in predicting indicators of internalizing psychopathology.

The Impact

This study investigated the application of item response theory (IRT) to expand the range of ability estimates for gifted (hereinafter referred to as high-achieving) students’ performance on an above-level test. Using a sample of fourth- to sixth-grade high-achieving students ( N = 1,893), we conducted a study to compare estimates from two measurement theories, classical test theory (CTT) and IRT. CTT and IRT make different assumptions about the analysis that impact the reliability and validity of the scores obtained from the test. IRT can also differentiate students based on the student’s grade or within a grade by using the unique string of correct and incorrect answers the student makes while taking the test. This differentiation may have implications for identifying or classifying students who are ready for advanced coursework. An exploration of the differentiation for Math, Reading, and Science tests and the impact the different measurement frameworks can have on classification of students are explored. Implications for academic talent identification with the talent search model and development of academic talent are discussed.

This study examined the reliability and validity of an expanded version of the Iowa Sleep Disturbances Inventory (ISDI; Koffel & Watson, 2010) in 2 samples (219 college students and 200 psychiatric patients). The expanded ISDI includes the scales of Sleep Paralysis and Sleep Hallucinations. These scales, along with the Nightmares scale, help define a higher order factor entitled Unusual Sleep Experiences. This factor was distinct from the factors of Insomnia and Lassitude that were reported previously. The expanded ISDI showed strong evidence of convergent and discriminant validity with the corresponding interview ratings on a clinician rating version of the ISDI. Mean convergent correlations were .68 in students and .70 in patients. Convergent correlations were significantly higher than discriminant correlations in 99.8% of the 624 comparisons. This study also reports the associations of higher order sleep factors with questionnaire and interview measures of pathological symptoms (e.g., depression, anxiety, dissociation, and schizotypy). The Lassitude factor was specific to dysphoria, whereas the Unusual Sleep Experiences factor was specific to posttraumatic stress disorder (PTSD) and dissociation. Finally, several ISDI scales showed strong evidence of specificity in relation to pathological symptoms; in particular, there were strong associations between (a) ISDI Fatigue and measures of dysphoria, (b) ISDI Nightmares and measures of PTSD, and (c) ISDI Sleep Hallucinations and measures of dissociation.

Properties Of Information

Purpose This paper aims to present the results of a systematic review of the evidence on psychometric properties of information literacy (IL) tests. Design/methodology/approach A two-stage search strategy was used to find relevant studies in two subject and three general databases. A descriptive review of test characteristics and psychometric properties was presented. The review included 29 studies describing psychometric properties of 18 IL tests. Findings It was found that the classical test theory was applied for all tests. However, the item response theory was also applied in three cases. Most of the psychometric tests were developed in the USA using ACRL IL competency standards. The most commonly used psychometric analyses include content validity, discriminant validity and internal consistency reliability. Research limitations/implications Only studies in English language are included in this review. Practical implications The study recommends that standards should be developed for the use and reporting of psychometric measures in designing IL tests. Librarians need to be trained in psychometric analysis of tests. Originality/value It is the first study that systematically reviewed psychometric properties of IL tests. The findings are useful for librarians who are teaching IL courses.

The purpose of this study was to examine the reliability and validity of the Received Support Scale of the Berlin Social Support Scales in a Canadian sample of English and French language melanoma patients ( N = 137). Participants received a skin self-examination education and completed self-report questionnaires. Exploratory factor analyses, reliability analyses, and independent samples t-tests were conducted. Findings support the unidimensionality of the Received Support Scale of the Berlin Social Support Scales. The psychometric similarities of the French and English versions of the scale, its strong internal consistency, as well as its convergent and discriminant validity support the use of the Received Support Scale of the Berlin Social Support Scales in patients with melanoma.

Background: There has been an increased effort to understand the nature of obsessive-compulsive disorder (OCD) in non-Western cultures. In particular, growing research has examined OCD in China, but there are no comprehensive instruments that measure both OCD severity and heterogeneity for characterizing samples. Aims: A validated, comprehensive measure that could be used in China would provide researchers with a useful instrument for evaluating severity and heterogeneity of OCD in a non-Western culture, allowing researchers to better understand the universal and cultural components that play a role in the nature of OCD. Method: The current investigation presents data on the reliability and validity of a Mandarin translation of the Obsessive-Compulsive Inventory-Revised (CH-OCI) using both a student (n = 1950) and clinical sample (n = 50 patients with OCD; n = 50 patients with anxiety as a comparison group). Results: Results support the factor structure, convergent and discriminant validity, criterion-related validity, test-retest reliability, and internal consistency of the CH-OCI. Conclusions: Validation of the instrument permits researchers and clinicians to measure OCD presentation in Mandarin-speaking samples.

Development And Validation

Background: Moral Growth Mindset (MGM) is a belief about whether one can become a morally better person through efforts. Prior research showed that MGM is positively associated with promotion of moral motivation among adolescents and young adults. We developed and tested the English version of the MGM measure in this study with data collected from college student participants. Methods: In Study 1, we tested the reliability and validity of the MGM measure with two-wave data (N = 212, Age mean = 24.18 years, SD = 7.82 years). In Study 2, we retested the construct validity of the MGM measure once again and its association with other moral and positive psychological indicators to test its convergent and discriminant validity (N = 275, Age mean = 22.02 years, SD = 6.34 years). Results: We found that the MGM measure was reliable and valid from Study 1. In Study 2, the results indicated that the MGM was well correlated with other moral and positive psychological indicators as expected. Conclusions: We developed and validated the English version of the MGM measure in the present study. The results from studies 1 and 2 supported the reliability and validity of the MGM measure. Given these, we found that the English version of the MGM measure can well measure one’s MGM as we intended.
