Abstract Objectives: to develop and analyze the psychometric properties of a questionnaire to assess community health workers’ knowledge on breastfeeding. Methods: this is a methodological study for the development of an instrument and analysis of validity and reliability. For the elaboration of items and identification of dimensions, a literature review was conducted. The items were submitted to the evaluation of a committee of judges, for apparent and content analysis. Construct validation was conducted through hypothesis test, with the participation of 282 community health workers and 19 pediatricians and obstetric nurses. For analysis and comparison of scores, the Mann-Whitney U test was used, assuming a significance level of 5%. Reliability was assessed using Cronbach's alpha coefficient and temporal consistency of the instrument was assessed using test-retest and Kappa analysis. Results: the final instrument presented a favorable opinion from the committee of judges. The hypothesis test showed that the questionnaire has discriminatory power to assess professionals with a higher level of knowledge (p<0.001). The Kappa test revealed that 63% of the items showed substantive to almost perfect agreement. The 32-item questionnaire showed a Cronbach's alpha of 0.794. Conclusion: the instrument developed was valid and reliable, allowing effective measurement of community health workers’ knowledge on breastfeeding.

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.

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.

This study intended to investigate the effect of social support and hope simultaneously and independently on resilience in adolescents. This study used quantitative methods with ex post facto design. Multistage random sampling techniques were used, which resulted in a sample of 291 adolescents in junior high school from Pagentan district, Central Java, Indonesia. They completed three questionnaires of social support, hope, and resilience. The validity of the instruments used was measured by psychology measurement experts (content validity). Then, the reliability of the instruments was analyzed using Cronbach’s alpha. The Cronbach’s alpha for each instrument was 0,854 (social support), 0,835 (hope), and 0,778 (resiliency). Data were analyzed using multiple regression at the significance level of 0,05. The results of the study reveal that there is an effect of social support and hope simultaneously and independently on resilience in adolescents. There are effective contributions of social support and hope to the resilience of about 41% (from social support 13,2% and hope of 27,8% respectively).

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.

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.
