Abstract The research aims to examine the reliability and validity of a new personal fable scale in West Java adapted from Lapsley dkk. (1989). New Personal Fable Scale consists of 46 items with 3 dimensions:  invulnerability, omnipotence, and personal uniqueness. The subjects of this study were 489 adolescents in West Java. The Rasch Model analysis from summary statistics, scalograms, item measure, person measure, and dimensionality map shows that this scale’s model is a good fit. The convergent validity test shows that the new personal fable scale which is adapted to Bahasa is valid. Reliability with a Cronbach Alpha method is 0,8 which means this scale is reliable. The results indicate that there are several items that need to be improved. This research provides information about the psychometric properties of egocentrism in adolescent especially personal fable in West Java.Keywords: Adolescents; Egocentrism; Personal Fable; Reliability; Validity  Abstrak Penelitian ini bertujuan untuk melihat reliabilitas dan validitas alat ukur personal fable adaptasi secara bahasa yang disesuaikan dengan faktor kultur budaya di Jawa Barat yang berasal dari Lapsley dkk.

<p>Hajj Instrument (HAJI) was developed to determine hajj pilgrim’s wellness. This study used Rasch measurement to evaluate the psychometric properties including validity and reliability of the HAJI. The respondents involved in this study were 300 comprised of Malaysian hajj pilgrims. HAJI consists of eight constructs namely physical care, physical activity, healthy eating, knowledge, mental toughness, intrapersonal, interpersonal and relationship with Creator and natures. Validity of each construct and content was determined through dimensionality, item fit and item polarity while the reliability was achieved by administered person and item separation. The results showed that the reliability for both item and person were 0.99 and 0.96 respectively. Besides, there were no items need to be dropped based on PTMEA CORR and INFIT MNSQ results. The study revealed that the items of HAJI fit the Rasch model as well as able to measure hajj pilgrim’s wellness. </p>

Metodas parengtas dviem etapais, naudojant empirinę skalių konstravimo strategiją. Pirmajame etape, taikant grupinio interviu ir ekspertinio vertinimo metodus, parengti psichologinio įgalinimo vertinimo teiginiai. Antrajame etape atliktas empirinis tyrimas (dalyvavo 189 tiriamieji, reprezentuojantys 8 Lietuvos organizacijas). Remiantis jo rezultatais parengtas lietuviškas psichologinio įgalinimo vertinimo klausimynas. Tiriamosios faktorių analizės metodu išskirti penki faktoriai: prasmė, entuziazmas, sprendimų priėmimas, autonomija ir pasitikėjimas kompetencija. Klausimynas pasižymi dideliu vidiniu patikimumu (bendras Cronbacho α = 0,909, atskirų subskalių nuo 0,755 iki 0,880), dideliu konvergentiniu ir diskriminantiniu konstrukto validumu tiek viso klausimyno, tiek atskirų penkių skalių lygmeniu.Pagrindiniai žodžiai: psichologinis įgalinimas, psichologinio įgalinimo klausimynas, patikimumas, validumas.EMPLOYEE PSYCHOLOGICAL EMPOWERMENT: PSYCHOMETRIC PROPERTIES OF THE LITHUANIAN QUESTIONNAIREMantas Tvarijonavičius, Dalia Bagdžiūnienė SummaryEmployee psychological empowerment is treated as a multidimensional construct manifesting in several dimensions. It has been researched for several decades using various scales depending on the definition of psychological empowerment chosen by a reasercher. However, there is a lack of widely applicable, compact instruments for a reliable and valid assessment of psychological empowerment. Furthermore, there has been a lack of empowerment research in Lithuania. Therefore, the purpose of this study is to construct a Lithuanian psychological empowerment questionnaire and to evaluate its psychometric properties (reliability and validity).The strategy of the empirical construction of a questionnaire was used. At first, statements to describe the concept of psychological empowerment were generated, using group interviews and expert evaluation. Fifteen final items were included into the Lithuanian Psychological Empowerment Questionnaire (LPEQ). Then, an empirical research was performed: 189 respondents from 8 organizations filled up the LPEQ, G.M. Spreizer (1995) Psychological Empowerment Questionnaire (PEQ), B. E. Ashforth (1990) Helplessness Scale, Intrinsic Motivation Scale (Warr et al., 1979), and socio-demografic questions.The results of the study have revealed that the LPEQ has a high internal reliability (Cronbach α = 0.909). Five factors were extracted using the exploratoryfactor analysis, three items each. Psychological empowerment was defined based on five dimensions: meaning, enthusiasm, decision making, authonomy, and trust in competence. The Cronbach α was between 0.755 and 0.880 for the dimension level. These five dimensions show support for the existing models of psychological empowerment (Spreitzer, 1995; Menon, 2001), but also they supplement these models with for instance, the dimension of enthusiasm.The convergent validity of the LPEQ was confirmed by strong correlations (p < 0.01) between the LPEQ and the PEQ subscales, and the Intrinsic Motivation Scale. It was supported by a negative correlation between the LPEQ subscales and the Helplessness Scale. Based on the analysis of correlations, the discriminant validity of the LPEQ dimensions’ levels was confirmed.In conclusion, the Lithuanian Psychological Empowerment Questionnaire (LPEQ) can be characterized as an instrument with appropriate psychometricproperties for the use in research and practice. Directions for the future research in the field have been offered.Key words: psychological empowerment, psychological empowerment questionnaire, reliability, validity.

The Rasch Model

This paper provides an elementary introduction to the one parameter psychometric model known as the Rasch model. It explains the basic principles underlying the model and the concepts of unidimensionality, local stochastic independence, and additivity in non-mathematical terms. The requirements of measurement procedures, the measurement of latent traits, the control on model fit, and the definition of a trait are discussed. It is argued that the Rasch model is particularly appropriate to understand the mutual dependence of test reliability and validity. Examples from foreign language listening comprehension tests are used to illustrate the application of the model to a test validation procedure.

The present study aims to analyze the psychometric properties of the revised version of the Adolescent Cyber-Aggressor scale (CYB-AGS). This scale is composed of 18 items that measure direct and indirect cyberbullying. A cross-sectional study was conducted using two independent samples of adolescents. The first sample included 1318 adolescents (52.6% girls) from 12 to 16 years old (M = 13.89, SD = 1.32). The second sample included 1188 adolescents (48.5% boys) from 12 to 16 years old (M = 14.19, SD = 1.80). First, to study the psychometric properties of the CYB-AGS, exploratory factor analysis was performed on Sample 1. Results indicated a two-factor structure: direct cyber-aggression and indirect cyber-aggression. Second, to verify the structure of the CYB-AGS, we selected Sample 2 to conduct confirmatory factor analysis and test the scale’s convergent validity with theoretically-related measures. Results confirmed the reliability and validity of the two-dimensional model. Moreover, measurement invariance was established. Finally, regarding convergent validity, positive correlations were obtained between cyberbullying and aggressive behaviors in school, anger expression, negative attitudes towards school, and transgression of norms. Furthermore, negative correlations were found between cyberbullying and attitudes towards institutional authority.

The main goal of the present study was to analyze the psychometric properties of the revised version of the Adolescent Cyber-Victimization Scale (CYBVICS). This scale is composed of 18 items that assess direct and indirect cyber-victimization. Two subsamples participated in the present study. Sample 1 included 1318 adolescents (47.4% boys) from 12 to 16 years old (M = 13.89, SD = 1.32). Sample 2 was composed of 1188 adolescents (51.5% girls) from 12 to 16 years old (M = 14.19, SD = 1.80). First, an exploratory factor analysis was conducted on sample 1. Results yielded a bifactor structure: direct cyber-victimization and indirect cyber-victimization. To confirm the structure of the CYBVICS, we selected sample 2 to perform confirmatory factor analysis and test its convergent validity with theoretically related measures. The results supported the reliability and validity of the two-factor model. In addition, measurement invariance was established. Related to convergent validity, positive correlations between cyber-victimization and peer victimization, depressive symptoms, and offensive communication with the mother and the father were found. Moreover, negative correlations were found between cyber-victimization and open communication with the mother and the father and family self-esteem.

Background and Purpose: The purpose of this study was to assess the psychometric properties of the Survey of Workplace Intimidation (SWI), including content and construct validity, factor structure, and internal consistency. Methods: A cross-sectional, descriptive study design was used for this study. The final sample consisted of 237 labor and delivery nurses who completed the SWI and the Practice Environment Scale of the Nursing Work Index (PES-NWI). Cronbach's alpha for the SWI was .930. Results: Content validity was obtained and the scale content validity index (S-CVI) was .943. Convergent validity was calculated by comparing the SWI with the PES-NWI, and the result was .408 (p .01). A factor analysis explained 61% of the variance and resulted in two factors: prescriber behaviors and nurses' responses to prescribers' behaviors. Conclusions: The SWI demonstrated acceptable reliability and validity.

This study examined the psychometric properties of the Chinese version of the Personal Diabetes Questionnaire (C-PDQ). The PDQ was translated into Chinese using a forward and backward translation approach. After being reviewed by an expert panel, the C-PDQ was administered to a convenience sample of 346 adults with Type 2 diabetes. The Chinese version of the Summary of Diabetes Self-Care Activities (C-SDSCA) was also administered. The results of the exploratory factor analysis revealed a one-factor structure for the Diet Knowledge, Decision-Making, and Eating Problems subscales and a two-factor structure for the barriers-related subscales. The criterion and convergent validity were supported by significant correlations of the subscales of the C-PDQ with the glycated hemoglobin values and the parallel subscales in the C-SDSCA, respectively. The C-PDQ subscales also showed acceptable internal consistency (α = .61–.89) and excellent test–retest reliability (intraclass correlation coefficients: .73–.96). The results provide preliminary support for the reliability and validity of the C-PDQ. This comprehensive, patient-centered instrument could be useful to identify the needs, concerns, and priorities of Chinese patients with type 2 diabetes.

Abstract Background A diagnosis of dementia presents individuals with both social and psychological challenges but research on self-stigma in dementia has been largely confined to qualitative approaches due to a lack of robust outcome measures that assess change. The Stigma Impact Scale (SIS) is the most commonly used measure of self-stigma in dementia but its suitability as a tool to assess change in a UK population is unclear. Thus, the aim of this study was to identify, adapt and evaluate the acceptability and preliminary psychometric properties of self-stigma measures for people with dementia for use as measures of change. Method A 4-step sequential design of identifying, selecting, adapting and testing psychometric measures as follows: 1) identification of stigma outcome measures through reviewing anti-stigma intervention literature, 2) selection of candidate measures through quality assessment (Terwee criteria) and expert consultation, 3) adaptation for UK dementia population (Stewart and colleagues Modification Framework) 4) testing of adapted measures in people living with dementia (N=40) to establish acceptability and preliminary reproducibility (test retest), criterion (concurrent with SIS) and construct (negative convergence with Rosenberg self-esteem scale) validity. Results Seven measures were identified from the review, but most were poor quality (Terwee range: 0–4). Three measures were selected for modification: Stigma Stress Scale; Secrecy subscale of the Stigma Coping Orientation Scale; Disclosure Related Distress Scale. Internal consistency and test-retest reliability were acceptable (.866≤α≤ .938; ICC .721–.774), except for the Stigma Stress Scale (α= .643) for which the component subscales (perceived harm, ability to cope) had stronger psychometric properties. Concurrent validity with the SIS was not established (r<.7) although there were significant correlations between total SIS and perceived harm (r=.587) and between internalized shame and secrecy (r=.488). Relationships with self-esteem were in the hypothesized direction for all scales and subscales indicating convergent validity. Conclusion Stigma scales from mental health are not readily adapted for use with people with dementia. However there is preliminary evidence for the acceptability, reliability and validity of measures of perceived harm, secrecy and stigma impact. Further conceptual and psychometric development is required.

AbstractIntroduction. The growing cultural diversity of Polish society creates new challenges for people who, in their professional activities, deal with culturally divergent people. Therefore, on the one hand, there is an urgent need for education and development in cross-cultural competences; on the other hand, there is a need to measure these competences with reliable and accurate methods.Aim. The goal of the present paper is recommendation of the Polish adaptation of the Cross-Cultural Competence Inventory (CCCI). In addition, the paper discusses the possible usage of the CCCI within the Polish healthcare system.Methods. The CCCI was adapted to Polish in a multistage process [1]. Briefly, it consisted of two studies, with 455 (Study 1) and 347 (Study 2) participants, in which the psychometric properties of the CCCI were evaluated in terms of reliability, internal consistency, factorial structure, test-retest reliability, and theoretical validity, criterion and convergent validity.Results. Although the original version of the CCCI was assumed to have a 6-dimensional factor structure, confirmatory factor analysis did not provide strong evidence for this assumption. However, as demonstrated in two studies, the Polish adaptation of the CCCI has satisfactory psychometric properties, such as reliability and validity (theoretical, criterion and convergent).Conclusions. Results of Study 1 and Study 2 support the conclusion that the CCCI can be successfully used in empirical research among healthcare professionals and students of medical courses. Future work may focus on further improvements of the CCCI by, for example, developing Polish standardized norms for different groups of professionals.
