Validation study of the Indonesian internet addiction test among adolescents

Background Internet addiction is a serious problem that can negatively impact both the physical and mental health of individuals. The Internet Addiction Test (IAT) is the most common used instrument to screen internet addiction worldwide. This study sought to investigate the psychometric properties of an Indonesian version of the IAT. Methods The IAT questionnaire was made the focus of forward translation, expert panel discussions, back translation, an item analysis (30 subjects), a pilot study (385 subjects), and field testing (643 subjects). Factor structure was analysed by exploratory (EFA) and confirmatory factor (CFA) analyses, whereas reliability was measured with Cronbach’s alpha coefficient. Results Factor analysis revealed that the Indonesian version of IAT, consisted of 3 domains, and had good validity (χ2 p < 0.001; RMSEA = 0.076; CFI = 0.95; SRMR = 0.057, and AIC = 784.63). The Cronbach’s alpha score is 0.855. A significant association was also observed between the level of internet addiction with gender (p = 0.027) and the duration of internet use per day (p = 0.001). Conclusion The Indonesian version of IAT provides good validity and reliability in a three-dimensional model. Therefore, it can be utilised as a tool for screening internet addiction in the Indonesian population.

Abstract Background: Internet addiction is a serious problem that can negatively impact both the physical and mental health of individuals. The Internet Addiction Test (IAT) is the most common and worldwide used instrument to screen internet addiction. This study sought to investigate the psychometric properties of an Indonesian version of the IAT.Methods: A total of 643 high school students participated in the study. The IAT questionnaire was made the focus of forward translation, expert panel discussions, back translation, a face validity study, a pilot study, and a psychometric properties evaluation. Factor structure was analysed by exploratory (EFA) and confirmatory factor (CFA) analyses, whereas reliability was measured with Cronbach’s alpha coefficient.Results: The factor analysis revealed that a three-factor model of the Indonesian version of the IAT identified in the EFA displays better psychometric properties than a one-factor model of the same. The Cronbach’s alpha score is 0.855. A significant association was also observed between the level of internet addiction with gender (p = 0.027) and the duration of internet use per day (p = 0.001).Conclusion: The Indonesian version of the IAT provides good validity and reliability in a three-dimensional model. Therefore, it can be utilised as a tool for screening internet addiction in the Indonesian population.

Background: Adolescents’ health choices have been widely researched, but the ethical basis of these choices, namely their rights, duties, and responsibilities, have been disregarded and scale is required to measure these. Objective: To describe the development of a scale that measures adolescents’ rights, duties, and responsibilities in relation to health choices and document the preliminary scale testing. Research design: A multi-phase development method was used to construct the Health Rights Duties and Responsibilities ( HealthRDR) scale. The concepts and content were defined through document analysis, a systematic literature review, and focus groups. The content validity and clarity of the items were evaluated by expert panel of 23 adolescents, school nurses, and researchers. We calculated the content validity index and the content validity ratio at on item and scale levels. Preliminary testing was conducted with 200 adolescents aged 15–16 years. Descriptive statistics, Cronbach’s alpha correlation, and statistics for the item-analysis were calculated. Ethical considerations: Ethical approval and permission were obtained according to national legislation and responsible research practice was followed. Informed consent was obtained from the participants and the parents were informed about the study. Findings: The Health Rights Duties and Responsibilities scale comprises of four sub-scales with 148 items: 15 on health choices, 36 on rights, 47 on duties, and 50 on responsibilities. The items had a 0.93 content validity index and a 0.85 content validity ratio. Cronbach’s alpha correlation coefficient was 0.99 for the total scale and the individual sub-scales scores were health choices (0.93), rights (0.97), responsibilities (0.99), and duties (0.98). Discussion: The findings are discussed in light of the ethical concepts and validity and reliability of the developed scale. Conclusion: The Health Rights Duties and Responsibilities scale defines and understands adolescents’ rights, duties, and responsibilities in relation to health choices and has good content validity. Further testing and refinement of the concepts are needed.

Introduction: Women's screening beliefs play an important role in their performance. Since a short form questionnaire is necessary in the assessment of screening beliefs in Iranian society, this study was conducted with the aim of psychometric evaluation of the Breast Cancer Screening Beliefs Questionnaire (BCSBQ) among Iranian women. Methods: In this cross-sectional methodological study, 300 Iranian women who were aged 18 years or older, and who were attending healthcare centers of Shahid Beheshti University of Medical Sciences, were selected in 2017-18. After a backward-forward translation procedure of BCSBQ was carried out, the face, content and construct validity of breast cancer-screening beliefs questionnaire were evaluated. In addition, the reliability was measured using the Cronbach's alpha and intra class correlation coefficients. Results: The results of the exploratory and confirmatory factor analysis were used to extract three distinct factors, including: attitude, knowledge, and barriers to screening. The three-factor model fit was accepted for all factors based on standard indices (RMSEA = 0.12, χ2 = 2.832, GFI = 0.87, AGFI = 0.8, CFI = 0.94, NFI = 0.92). In addition, the instrument’s reliability was measured using the Cronbach's alpha coefficient. The instrument had an appropriate Cronbach alpha (0.78). The interclass correlation coefficient was obtained to be 0.93 within a range of 0.83-0.97. Conclusion: The three-factor structure of the BCSBQ-12 had appropriate validity and reliability among Iranian women. Considering its appropriate psychometric properties, this instrument can be employed in subsequent studies to measure women's breast cancer screening beliefs in Iran.

Simple Definition

The Psychology of Religion has had a tradition measuring things that are seemingly difficult to measure, such as one’s level of religiosity or spirituality – concepts that are polysemantic, so do not have a simple definition. In doing so, researchers have developed scales to measure such constructs. This trend in Psychology of Religion research will continue as researchers start to conduct studies in non-Western Educated Industrialized Rich Democratic (WEIRD) populations, as they will require new scales that are appropriate for the way that these populations conceptualize religiosity and spirituality. Scale construction takes multiple steps, which most researchers are well-acquainted with. One important step is to demonstrate both validity and reliability. In the Psychology of Religion, an overwhelming majority of researchers use Cronbach’s alpha to estimate scale reliability. However, alpha has multiple preconditions that can easily be violated in psychology research that are rarely tested for, let alone adjusted for. Much like with using parametric statistical analyses when parametric assumptions are violated, this approach may be leading to inaccurate reporting. This article will discuss; (1) whether alpha should be used at all in Psychology of Religion research and, if so, when it is appropriate; (2) introduce another estimate of scale reliability, Omega, and show how and it might be calculated; (3) provide examples of how these techniques might be taught to students studying Psychology of Religion at undergraduate and higher levels. In doing so, I hope to move the entire field of Psychology of Religion forward in terms of methodological rigor.

Patient-centredness in care is a core healthcare value and an effective healthcare delivery design requiring specific nurse competences. The aim of this study was to assess (1) the reliability, validity, and sensitivity of the Finnish version of the Patient-centred Care Competency (PCC) scale and (2) Finnish nurses’ self-assessed level of patient-centred care competency. The PCC was translated to Finnish (PCC-Fin) before data collection and analyses: descriptive statistics; Cronbach’s alpha coefficients; item analysis; exploratory and confirmatory factor analyses; inter-scale correlational analysis; and sensitivity. Cronbach’s alpha coefficients were acceptable, high for the total scale, and satisfactory for the four sub-scales. Item analysis supported the internal homogeneity of the items-to-total and inter-items within the sub-scales. Explorative factor analysis suggested a three-factor solution, but the confirmatory factor analysis confirmed the four-factor structure (Tucker–Lewis index (TLI) 0.92, goodness-of-fit index (GFI) 0.99, root mean square error of approximation (RMSEA) 0.065, standardized root mean square residual (SRMR) 0.045) with 61.2% explained variance. Analysis of the secondary data detected no differences in nurses’ self-evaluations of contextual competence, so the inter-scale correlations were high. The PCC-Fin was found to be a reliable and valid instrument for the measurement of nurses’ patient-centred care competence. Rasch model analysis would provide some further information about the item level functioning within the instrument.

Background Evidence-based medicine (EBM) is a widely accepted scientific advancement in clinical settings that helps achieve better, safer, and more cost-effective healthcare. However, presently, validated instruments to evaluate healthcare professionals’ attitude and practices toward implementing EBM are not widely available. Therefore, the present study aimed to determine the validity and reliability of a newly developed knowledge, attitude, and practice (KAP) questionnaire on EBM for use among healthcare professionals. Methods The Noor Evidence-Based Medicine Questionnaire was tested among physicians in a government hospital between July and August 2018. Exploratory factor analysis and internal consistency reliability-based Cronbach’s alpha statistic were conducted. Results The questionnaire was distributed among 94 physicians, and 90 responded (response rate of 95.7%). The initial number of items in the KAP domains of the Noor Evidence-Based Medicine Questionnaire were 15, 17, and 13, respectively; however, two items in the practice domain with communalities <0.25 and factor loadings <0.4 were removed. The factor structure accounted for 52.33%, 66.29%, and 55.39% of data variance in the KAP domains, respectively. Cronbach’s alpha values were 0.81, 0.81, and 0.84 for KAP domains, respectively, indicating high reliability. Conclusions This questionnaire can be used to evaluate the knowledge, attitudes, and behaviour of healthcare professionals toward EBM. Future testing of this questionnaire among other medical personnel groups will help expand the scope of this tool.

The validity analysis of the scale for the data collected was performed with exploratory factor analysis and item-total correlation tests, while the property of reliability was determined using the Cronbach’s alpha internal consistency coefficient and the stability test was carried out by determining the relationship between two applications conducted at an interval of the five weeks. The scale, which is called the “Scale for Determining the Civic-Mindedness Levels of Individuals” is a five-step Likert-type scale and consists of 27 items that can be collected under three factors. The factor names are “Openness to Criticism/Development”, “Participation/Activeness” and “Lack of Prejudice/Flexibility”. The KMO value of the scale was 0.956; and the Bartlett Test values were x2=11001.719; sd=351; p<0.000. Items in the scale accounted for 56.619% of the total variance. As a result of the confirmatory factor analysis, the χ2 value was 808.07 and the degree of freedom was 321. Χ2/df is 2.51. The fit indices of the scale were determined as RMSEA=0.067; S-RMR=0.049; NFI=0.97. The item-total corrected correlation coefficients of the items in the scale varied between 0.40 and 0.703 (p<.01). The reliability coefficient of the scale was Cronbach’s alpha at 0.954 and the stability coefficients of the items were between 0.496 and 0.674 (p<,01).

Heart Failure Questionnaire

The Minnesota Living with Heart Failure Questionnaire (MLHFQ) has been developed to measure health-related quality of life (HRQoL) status of Heart Failure (HF) patients. The aim of this study was to translate MLHFQ into the Persian version and assess the validity and reliability of the translated version. We used a forward-backward procedure for translation. In a cross-sectional study, 105 HF patients and 50 healthy subjects were selected to assess the reliability and construct validity of the instrument. The face and content validity were used to assess the questionnaire validity. Validity was examined on the HF patients group, using the Persian version of the Short form-36 health survey (SF-36) Questionnaire. In order to assess the questionnaire’s reliability, the Intraclass correlation coefficient (ICC) and Cronbach’s alpha were calculated. Test-retest reliability was examined by re-administering the MLHFQ after 2 weeks. Test-retest results demonstrated that the Persian version has excellent reliability (ICC for all 2 domains were higher than 0.91, P≤0.000). Internal consistency for Physical domain (PD), emotional domain (ED) and total scores using Cronbach’s alpha were 0.90, 0.84 and 0.92, respectively. ICC for PD, ED and total scores were 0.95, 0.94, and 0.97, respectively. Good and very good Pearson's Correlation Coefficient was seen between MLHFQ and SF-36 (r= -0.47 to -0.775, P≤0.000 for PD; r= -0.47 to -0.65, P≤0.000 for ED). The Persian version of the MLHFQ had satisfactory reliability and validity for assessing HRQoL status of Iranian HF patients. © 2019 Tehran University of Medical Sciences. All rights reserved.

ABSTRACT Objective: To validate the construct and test the reliability of the Brazilian version of Hypertension Knowledge-Level Scale. Methods: Methodological research with 220 participants in a primary health care unit from Curitiba, Paraná. The data were collected with a social demographic questionnaire and the Brazilian version of the scale. The construct validity and reliability were assessed using Cronbach’s Alpha, Pearson’s Correlation and Analysis of Variance. The discriminant validity was verified comparing groups of people with hypertension and without, using T test. Results: Cronbach’s Alpha was 0.74. The groups comparison showed that people with hypertension had better results (p<0,001). Pearson’s Correlation showed that the questions measure different aspects of the same construct, justifying its organization in subdimensions. Conclusion: The Brazilian version of Hypertension Knowledge-Level Scale is a reliable instrument, which had its construct and criterion validated to measure knowledge about hypertension among Brazilian people. It can help health professionals with planning educative actions.

Abstract: Introduction: The humanities are associated with the improvement of medical students’ personal qualities. To date, there are no research instruments that quantify the exposure of medical students have to the humanities. Hence, the availability of a questionnaire with such characteristics in Brazilian Portuguese sets a precedent for the planning and implementation of educational strategies and policies addressing this topic. Objective: to translate and transculturally adapt the “HUMANITIES SCORE (LIFE EXPERIENCES + ATTITUDES) questionnaire, determine its validity and reliability, as well as identify the type of exposure to the humanities of the assessed population. Method: The original version of the questionnaire, written in English, was translated according to what is recommended by the specialized literature, with the addition of some activities in the humanities field, as per the original authors’ suggestion. The translated instrument underwent a pre-test with 31 medical students for semantic validation, followed by the application of its final version to 258 students. The exploratory and the confirmatory factorial analyses were applied to assess the instrument with its internal consistency was checked with Cronbach’s Alpha coefficient. Result: The final questionnaire was administered to the students to verify their type of exposure to the humanities. After the statistical tests were carried out, the final version of the instrument, named “Escala de Exposição às Humanidades” (EEH), included 17 items with Likert-scale responses with five options each, and obtained a Cronbach’s alpha of 0.689. The mean score of the students’ exposure was 1.72 ± 0.37, being influenced by the period at medical school, the number of volunteer social activity experiences, the participation in religious groups, the practice of meditation, and the involvement in political activities. Variables such as female gender, engagement in previous actions related to the humanities before starting medical school and in religious ceremonies positively influenced the students’ opinion about the importance of the humanities for the medical curriculum. Conclusion: The EEH demonstrated reliability in its structure and content, allowing correlations between the students’ exposure to humanities and their opinion about the importance of human sciences in the medical curriculum. It constitutes the first instrument that aims at measuring the humanities exposure rate in Brazil; however, further studies must be carried out, to better validate the instrument.
