Research Type

In this study, the authors constructed and validated instrument to measure examiners’ disposition towards knowledge of examination malpractice indicators of West African Examinations Council (WAEC). Consequently, scale development research type of single-subject design was employed. The sample for the two phases consisted of nine hundred and sixty (960) WAEC mathematics examiners from 9 marking centres, which were drawn randomly from Osun, Ogun and Ondo State, Nigeria. The instrument used for data collection was Examiners’ Attitude Towards Knowledge of Malpractice Indicators Scale (EAKMIS). Data were analyzed using Principal Component Analysis (PCA), Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA) and Ordinal Alpha. The results showed that the scale was reduced from twenty (20) to eleven (11) items across three (3) dimensions. Final compliance indices were: χ2 = 457.54, p = 0.01, RMSEA= 0.03, GFI = 0.96, AGFI = 0.96, TLI = 0.94, NFI = 0.90, SRMR= 0.01, CFI= 0.91 and IFI= 0.91. The ordinal alpha reliability index for the three (3) factors of EAKMIS was 0.79, while the reliability index for each of the subscale of the EAKMIS ranged from 0.85 to 0.93. It was recommended that there should be intensive training and re-training for all the examiners by the examining body where issues related to the detection of examination malpractice cases while marking would be discussed.

Inadequate health literacy decreases physical activity. This study aimed to develop and examine psychometrics of physical activity health literacy in Iranian older adults. This methodological work was conducted in two phases. Phase 1 consisted of extensive studies review and qualitative study to extract and design the items. The psychometrics were measured in Phase 2 included content, faceconstruct validities, reliability, and stability. The collected data were analyzed in SPSS (version 25.0) and AMOS (version 24.0). The results of the exploratory factor analysis showed four factors— information evaluation, reading skill, perception, and decision making—and used information that explained 70.08% of the variance. The model’s fitness was supported by confirmatory factor analysis. Internal consistency based on Cronbach’s alpha was .89 with composite reliability >0.85. Stability was confirmed through the test–retest method and intraclass correlation coefficient (.89–1). Psychometrics of physical activity health literacy in Iranian older adults supported validity and reliability of the tool.

The purpose of this study is to identify employability skills among aspiring engineering graduates and develop measurement scale to assess their skill sets. This research has been conducted in two phases: Phase 1 covers the scale development process and Phase 2 covers exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and validation. The findings of EFA resulted in ten factors of employability. Subsequently, CFA identified nine different factors: leadership, critical thinking, numeracy, sociability, using technology, planning and organizing, problem-solving, teamwork, and emotional intelligence skills. The values of CFA met the acceptance level of different fit indices and thus, resulted in a good model fit. Further, the internal consistency of the total scale yielded Cronbach's alpha value (α = 0.82). The threshold values of CR, AVE, and MSV also met the required criteria. Thus, it received a valid and reliable 26-item measurement scale of employability which can prove to be useful for academia, students, and employers in computer science and information technology.

Addenbrooke’S Cognitive Examination

Background: The Addenbrooke's Cognitive Examination (ACE) is used to measure cognition across a range of domains in dementia. Identifying the order in which cognitive decline occurs across items, and whether this varies between dementia aetiologies could add more information to subdomain scores. Method: ACE-Revised data from 350 patients were split into three groups: Alzheimer's type (n = 131), predominantly frontal (n = 119) and other frontotemporal lobe degenerative disorders (n = 100). Results of factor analysis and Mokken scaling analysis were compared. Results: Principal component analysis revealed one factor for each group. Confirmatory factor analysis found that the one-factor model fit two samples poorly. Mokken analyses revealed different item ordering in terms of difficulty for each group. Conclusion: The different patterns for each diagnostic group could aid in the separation of these different types of dementia.

The A-ADS is one the first validated measures of attitudes of dementia in adolescents, though further validation is needed. 630 adolescents were recruited from secondary schools in England. A Principal Component Analysis was completed ( n = 230) followed by a Confirmatory Factor Analysis ( n = 400). Reducing the A-ADS into a single factor, 13-item measure (Brief A-ADS) improved the model fit of the measure (χ2 = 182.75, DF = 65, CMIN/DF = 2.81, p < 0.001, CFI = 0.90, RMSEA = 0.07). The scale demonstrated good internal consistency, good predictive and concurrent validity. Building on the validation of the A-ADS, the Brief A-ADS is suitable to capture attitudes towards dementia amongst adolescents.

IntroductionH&F Multidimensional Perfectionism Scale is a widely used measure of perfectionism developed to measure Self-oriented perfectionism (SOP), Socially-prescribed perfectionism (SPP) and Other-oriented perfectionism (OOP) dimensions. The original scale comprises 45-likert items. We have previously developed a short version of The H&F-MPS, with 13 items, showing adequate validity in a sample of university students, using principal component analyses method with factors varimax rotation.ObjectiveTo examine the factor structure of the H&F-MPS13 with confirmatory factor analysis (CFA), using a different sample of Portuguese university students.MethodsThe sample comprises 245 university students (68.9% females), with a mean age of 20.95 years (SD= 2.19; range= 17–33) who completed the H&F-MPS13. CFA was used to test the model suggested by prior exploratory factor analyses of H&F-MPS13.ResultsAfter correlated errors, we obtained a good fit for the second-order factor (X2/d= 2.577; CFI= 0.928; GFI= 0.915, RMSEA= 0.080; P[rmsea ≤ 0.05] = 0.001). The H&F-MPS13 showed acceptable internal consistency (α= 0.77) and the three dimensions presented Cronbach's alphas ranging between acceptable and good (α OOP = 0.67; SPP = 0.73; SOP = 0.89).ConclusionsThe H&F-MPS13 obtained through CFA is a reliable and valid measure to assess perfectionism in Portuguese university students.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The aim of this study is to develop a scale that measures active citizenship self-efficacy. Because self-efficacy identifies a person’s perceived beliefs towards his or her capacity and ability to succeed a task, it has a motivational and causative role in one’s possible acts or behaviors. For his reason, measuring active citizenship behaviors through self-efficacy is of special importance for understanding citizenry behaviors. The study explores the development of the Active Citizenship Self-Efficacy Scale (ACSES) and its psychometric properties. Participants consist of 414 university students, of which 326 were female and 88 were male. The validity of the scale was tested via explanatory and confirmatory factor analysis. The results for explanatory factor analysis with principal component solution indicated three factor structure that explains 57,17 percent of the total variance. Since the chi square test indicated that our data was meaningful, we also conducted a confirmatory factor analysis and found the indices of goodness of fit as for RMSEA = .070, GFI = .90, CFI = .97, NFI =.95, RFI = .95, AGFI = .87, IFI = .97 and NNFI = .96. These results from both explanatory and confirmatory factor analysis indicated that scale obtains construct validity criterion. The Cronbach alphas’ of the ACSES for the total 18 items and subdomains were found .90, and .84, .82, and .86 respectively. Since the determination of citizens’ self-efficacy level can in part reflect the results of citizenship education and practices we believe that this scale has a potential use in citizenship studies.Extended English abstract is in the end of PDF (TURKISH) file. ÖzetBu çalışmanın amacı aktif yurttaşlık öz yeterliği ile ilgili bir ölçme aracı geliştirmektir. Öz-yeterlik kişinin bir işi başarmada kendi kendisine yönelik algı inancını yansıttığı için olası davranışlar üzerine nedensel ve motivasyonel bir etkiye sahiptir. Bu nedenle, aktif yurttaşlık davranışlarını öz-yeterlik aracılığıyla ölçmek yurttaşlık davranışlarını anlamada önemlidir. Çalışmada Aktif Yurttaşlık Öz-yeterlik Ölçeği (AYÖYÖ) geliştirilerek psikometrik özellikleri tanıtılmıştır. Ölçek, 18 soru ve üç boyuttan meydana gelen bir ölçme aracıdır. Araştırmanın katılımcıları 326’sı kadın; 88’i erkek olmak üzere 414 üniversite öğrencisidir.  Elde edilen verilere açıklayıcı ve doğrulayıcı faktör analizi yapılarak ölçeğin geçerliliği test edilmiştir. Açıklayıcı faktör analizinde ölçeğin üç faktörlü yapısının toplam varyansı açıklama oranının % 57,17 olduğu görülmüştür. Doğrulayıcı faktör analizinde ki-kare değeri anlamlı bulunmuştur; uyum indeksleri ise RMSEA = .070, GFI = .90, CFI = .97, NFI =.95, RFI = .95, AGFI = .87, IFI = .97 ve NNFI = .96 olarak tespit edilmiştir. Bu sonuçlar, ölçeğin yapı geçerliğinin sağladığını göstermektedir. AYÖYÖ’nin tüm maddeler için Cronbach alpha güvenirlik katsayısı .90, alt boyutlar için ise .84, .82. ve .86  olarak tespit edilmiştir. Yurttaşların öz-yeterlik düzeylerinin tespit edilmesi yurttaşlık eğitimi ve uygulamalarının sonuçlarını görme açısından önemli olduğundan bu ölçme aracının yurttaşlık araştırmalarında yaygın kullanım potansiyeline sahip olduğunu düşünüyoruz.

The present study is based on the development of scale to measure schadenfreude in adolescents. The objectives of the study are twofold i.e., the development of an indigenous scale to measure schadenfreude among adolescents and to establish the validity of this scale. To achieve these goals, study comprised of two phases. Item pool was generated on the basis of literature as well as content analysis of the information obtained through focus groups and it was finalized through committee approach. Factor structure of the scale was determined by conducting Exploratory Factor Analysis (N=330). In Phase-II, psychometric properties of the scale were established by conducting Confirmatory Factor Analysis on an independent sample (N=320). Descriptive statistics, alpha reliabilities and item total correlations were computed. The final scale comprised of 28 statements with six domains included Rivalry, Negative Emotions, Unfairness, Worthlessness, Comparison Bias, and Helplessness. It is a measure schadenfreude among adolescents.

Background Neglect and abuse of older adults are still prevalent in communities of developing countries, a situation that could discourage active and healthy behaviors in community-dwelling older adults. Methods This study used the cross-sectional and correlational approaches to construct a scale measuring neglect and abuse in older adults living in the community. The study population was all (3,211) older adults who were resident in Accra and were part of the database of the Social Security and National Insurance Trust. Participants were 515 individuals who met some inclusion criteria. Three steps were followed to determine an initial set of 11 items, and principal component analysis with varimax rotation and confirmatory factor analysis were used to select relevant items and assess the psychometric properties of the final scale. Results Principal component analysis with varimax rotation yielded a two-factor solution on all 11 items. The first factor extracted was “discrimination and exploitation,” which accounted for a variance of 53.9% out of total variance of 70.8%. The scale had a good internal consistency (Cronbach’s α = .90, factor loading ≥0.50). Confirmatory factor analysis confirmed the two-factor solution and produced satisfactory convergent and discriminant validity. Conclusion It is concluded that 11 items that make up 2 factors are potential indicators of neglect and abuse of older adults at the community level. Finally, neglect and abuse of older people in the community can contribute to an increase or decrease in social activity.
