SummaryAims – To assess the validity and reliability of the GHQ-12 in Portugal. Methods – Using a standard ‘forwardbackward’ translation procedure, the English language version of the questionnaire was translated into Portuguese. To test reliability the internal consistency was assessed by Cronbach's alpha coefficient. Validity was performed using convergent validity. Finally, the factor structure of the questionnaire was extracted by performing principal component analysis using varimax rotation. Results – In all 790 undergraduates entered into the study. Reliability analysis showed satisfactory result (Cronbach's alpha coefficient = 0.91). Convergent validity indicated a significant negative correlation between the GHQ-12 and social support scores as expected (r = -0.54, P < 0.001). The principal component analysis showed that the GHQ-12 was a measure with two-factor structure. Conclusion – The Portuguese version of the GHQ-12 has a good structural characteristic for measuring psychological well being.Declaration of Interest: None.

The Monash Dog–Owner Relationship Scale (MDORS) is a questionnaire that is used to evaluate the perceived relationship between humans and their dog. This questionnaire was originally only formulated and validated in English, which limits its use among non-English speaking individuals. Although a translation could be made, the translation of questionnaires without additional validation often impairs the reliability of that questionnaire. Therefore, the aim of this study was to validate a translation of the MDORS that is suitable for use among native Dutch speakers. To achieve this, a Dutch translation of the MDORS was made and checked for spelling/grammar mistakes, readability, feasibility, and clarity. A test–retest comparison was subsequently performed on the translation together with a calculation of Cronbach’s alpha score and principal component analysis (PCA). Through the PCA, we found that the three-factor model of the original MDORS was also largely present in the Dutch translation. However, deviations were also found, as several questions did not achieve high PCA scores in their original factor. Therefore, we propose that these questions are excluded from the Dutch MDORS.

Self Forgiveness

Individu memiliki cara yang berbeda dalam merespon kesalahan yang diperbuat. Ada yang cepat memaakan kesalahan diri sendiri, namun ada yang butuh waktu lama atau bahkan membenci diri sendiri karena kesalahan yang diperbuat. Konsep penting terkait hal tersebut yaitu pemaafan diri yang ternyata berimbas positif pada kesejahteraan psikologis dan kesehatan mental. Pengukuran pemaafan diri kemudian menjadi penting untuk mendukung semakin banyaknya penelitian pemaafan diri. Namun begitu, meski di luar sudah dikembangkanbeberapa skala pemaafan diri, di Indonesia belum banyak ditemukan penelitian yang khusus mengembangkan atau mengadaptasi skala ini. Dalam tulisan ini, peneliti bertujuan mengembangkan skala pemaafan diri yang diharapkan menjadi alat ukur yang valid dan reliabel. Peneliti melakukan tujuh tahapan pengembangan skala yaitu: (1) penentuan konstrak ukur, (2) penyusunan indikator-aitem, (3) pengujian validitas isi, (4) uji coba, (5) uji lapangan, (6) seleksi aitem, dan (7) penyusunan skala final. Hasil akhir penelitian ini dihasilkan 13 aitem skala pemaafan diriyang memiliki daya beda berkisar .337 hingga .676 dan reliabilitas Cronbach’s alpha ditemukan .798 (dimensi mengakui tanggung jawab) dan .779 (dimensi memperbarui diri). Skala pemaafan diri juga memiliki struktur internal yang cukup baik. Hasil analisis faktor dengan principal component analysis pada 13 aitem didapat nilai KMO=.833, Barlett’s Test of sphrecity X2(78)=447.594, p<.01. Dua dimensi pemaafan diri mampu menjelaskan sebesar 49.891% varian.

Kemajuan teknologi Internet di dunia memunculkan fenomena baru dalam penggunaan media sosial. Media sosial tidak hanya digunakan untuk berhubungan dengan orang lain, namun juga untuk membentuk kesan yang baik, bahkan untuk melakukan manipulasi. Pengguna media sosial seringkali memanipulasi penampakan mereka di media sosial, seperti mengedit foto atau memalsukan identitas mereka. Fenomena ini termasuk dalam Deception Behavior (perilaku menipu). Meski fenomena ini sering dijumpai, belum banyak studi yang berupaya untuk mengukur kecenderungan seseorang untuk terlibat dalam perilaku menipu di media sosial. Oleh karena itu, penelitian ini bertujuan untuk membuat skala Deception Behavior in Social Media berdasarkan teori Utz (2005). Partisipan penelitian adalah pengguna aktif media sosial sebanyak 457 orang di wilayah Jabodetabek dengan rentang usia 15-40 tahun. Penelitian ini meliputi pembuatan butir dan pengujian dengan menggunakan Principal Component Analysis (PCA), dilanjutkan dengan Confirmatory Factor Analysis (CFA). Sementara itu, reliabilitas diuji dengan menggunakan koefisien Cronbach’s Alpha. Hasil penelitian menunjukkan bahwa skala ini reliabel untuk mengukur deception behavior di media sosial.

AbstractUsing categorical principal component analysis, we aimed to determine the relationship between health care-associated infections (HAIs) and diagnostic categories (DCs) in patients with acute heart disease using data collected in the Spanish prospective ENVIN-HELICS intensive care registry over a 10-year period (2005–2015). A total of 69,876 admissions were included, of which 5597 developed HAIs. Two 2-component CATPCA models were developed. In the first model, all cases were included; the first component was determined by the duration of the invasive devices, the ICU stay, the APACHE II score and the HAIs; the second component was determined by the type of admission (medical or surgical) and by the DCs. No clear association between DCs and HAIs was found. Cronbach’s alpha was 0.899, and the variance accounted for (VAF) was 52.5%. The second model included only admissions that developed HAIs; the first component was determined by the duration of the invasive devices and the ICU stay; the second component was determined by the inflammatory response, the mortality in the ICU and the HAIs. Cronbach’s alpha value was 0.855, and VAF was 46.9%. These findings highlight the role of exposure to invasive devices in the development of HAIS in patients with acute heart disease.

17077 Background: The cancer load in India is enormous and majority of the cases present in an advanced stage. There is no valid translation of 12-item General Health Questionnaire (GHQ-12) in Kannada, which is a simple but indispensable tool in the comprehensive cancer care (both for metastatic and in adjuvant settings). Therefore we thought of developing and validating the GHQ-12 Questionnaire into Kannada language. Methods: The study was conducted at kidwai memorial institute of Oncology, Bangalore, a tertiary cancer center with an annual attendance of 16,000 new cases. We have chosen educated patients who can speak and write both English and Kannada. We used ’forward-backward’ translation procedure into Kannada. We used scores from 0–3 for the Questionnaire. Total score for both languages was calculated. Internal consistency was assessed by Cronbach's alpha coefficient. Validity was performed using convergent validity. Finally, the factor structure of the questionnaire was extracted by performing principal component analysis using oblique factor solution. Results: A total of 118 patients with various malignancies were entered into the study. The mean age was 36.8 ± 12.1 years. The mean GHQ score was 21.6 ± 9.1 for the English and 22.6 ± 8.1 for Kannada. Reliability analysis showed satisfactory result (Cronbach's alpha coefficient = 0.79). The principal component analysis with oblique rotation solution showed that the GHQ-12 was a measure of psychological morbidity with four -factor structure that jointly accounted for 48 % of the variance. Conclusions: The Kannada version of the GHQ-12 is a reliable and valid instrument with a good structural characteristic. It can be used for measuring psychological well being at our institute for those patients who can read and write only Kannada. No significant financial relationships to disclose.

Background and Aims: Mentalized affectivity is a new approach that expresses the process of emotion regulation through a dynamic perspective. Since social-cognitive variables and cultural context play a major role in the process of mentalized affectivity, the present study aimed to assess the psychometric properties of the Mentalized Affectivity Scale in Iran. Materials and Methods: A total of 447 students were selected via the convenience sampling method. The Persian version of Mentalized Affectivity Scale was administered simultaneously with other scales. exploratory and confirmatory factor analyses was used to evaluate the validity of the scale. Moreover, convergent validity and divergent validity of this scale were assessed with other scales. The reliability of the scale was calculated by Cronbach's alpha, coefficient theta, and composite reliability. Results: The results of exploratory factor analysis showed four factors of emotion recognition, emotion processing, emotion tracing, and emotion expression. The significant correlation of factors with the used scales pointed to the content validity and divergent validity of the scale. Cronbach's alpha coefficient for the entire scale was 0.93. The composite reliability of the factors was in the range of 0.82-0.89, and the coefficient theta of the scale was reported as 0.98. With respect to average variance extracted (AVE) greater than 0.5 and composite reliability greater than 0.8, the convergent validity of the factors was confirmed. Conclusion: As evidenced by the obtained results, the Persian version of the Mentalized Affectivity Scale is a valid scale in the field of emotion regulation and social cognition that can be used for Iranian populations. The factor structure includes four factors.

Abstract Background The Harris Hip Score (HHS) is a widely used Patient-Related Outcomes score. It measures pain and function levels in patients with hip pathologies. Objectives The main objective of this study is to translate and culturally adapt the HHS into Arabic, and to further assess the reliability and validity of translated version Material & Methods 110 patients participated in this survey. The internal consistency tests were performed using Cronbach’s alpha. Test-retest reliability (intra-correlation coefficient), convergent construct validity, convergent validity, floor & ceiling effects and responsiveness was also calculated. In order to measure the level of agreement, Bland-Altman Plot, forest Plots are performed. Results Test reliability for the first testing situation - calculated using Cronbach's alpha - was 0.98 for the pain subscale, 0.98 for the stiffness, and 0.99 for the physical function subscale. For the second testing, reliability was 0.99, 0.97, and 0.99 (pain, stiffness, and physical function, respectively). This only proves that WOMAC is an instrument with good reliability. Same calculation of Cronbach’s alpha was essential to testing the reliability of the Harris Hip Score. For each of the three testing occasions the reliability was very good or excellent – α 1 = 0.92, α 2 = 0.91, and α 3 = 0.90. Intra-class correlation coefficient was good with the score of 0.76 (95% CI 0.44-0.88). Conclusion Overall, Arabic version of HOOS could be used as diagnostic tool for patients with hip problems, when it comes to information about the overall condition of the patient, especially about the improvement or deterioration, however, it is important to be cautious using HHS when the change magnitude of patient’s condition is investigated, since there is a potential probability that the level of improvement of the patient’s condition will be overestimated by HHS.

Reflective Measurement

Well being is a multidimensional phenomenon, that cannot be measured by a single descriptive indicator and that, it should be represented by multiple dimensions. It requires, to be measured by combination of different dimensions that can be considered together as components of the phenomenon. This combination can be obtained by applying methodologies knows as Composite Indicators (CIs). CIs are largely used to have a comprehensive view on a phenomenon that cannot be captured by a single indicator. Principal Component Analysis (PCA) is one of the most popular multivariate statistical technique used for reducing data with many dimension, and often well being indicators are obtained using PCA. PCA is implicitly based on a reflective measurement model that it non suitable for all types of indicators. Mazziotta and Pareto (2013) in their paper discuss the use and misuse of PCA for measuring well-being. The classical PCA is not suitable for data collected on the territory because it does not take into account the spatial autocorrelation present in the data. The aim of this paper is to propose the use of Spatial Principal Component Analysis for measuring well being in the Italian Provinces.

Background: Infertility is a public health problem and can lead to depressive symptoms. In recent years, the WHO-five Well-being Index (WHO-5) has been used as a screening measure for depression, but study on psychometric properties in people with infertility is scarce. The objective of this study was to examine the reliability and validity of the Persian version of the WHO-5 in people with infertility. Methods: Overall, 539 infertile patients from a referral infertility center in Tehran, Iran in the period between May and Aug 2017, completed the WHO-5, along with other psychological measures: the Patient Health Questionnaire-9 (PHQ-9) and the Hospital Anxiety and Depression Scale (HADS). Construct validity and internal consistency of WHO-5 were evaluated using confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with PHQ-9 and HADS. Results: The prevalence of poor well-being was 44.3% and that of depression was 18.6%. CFA confirmed the unidimensional factor structure of the WHO-5. Internal consistency of the WHO-5 was good (Cronbach’s alpha=0.858). The WHO-5 significantly correlated with the PHQ-9 (r=-0.522), HADS-anxiety (r=-0.524) and HADS-depression (r=-0.630), confirming convergent validity. Conclusion: The WHO-5 is a short and easy to use questionnaire with satisfactory reliability and validity that appears suitable for use as a screening test for depressive symptom in infertile people. In addition, the prevalence of depression and poor well-being was very high in this population.
