Abstract Background Vaccination rates for measles, mumps, and rubella (MMR) and diphtheria, tetanus, pertussis, and polio (Tdap-IPV) are not optimal among German adolescents. Education in combination with easy access to vaccination may be a promising approach to improve vaccination rates. The present paper describes a pilot study of a planned cluster randomized controlled trial (cRCT) in which we aim to improve MMR and Tdap-IPV vaccination rates together with knowledge and self-efficacy in a school setting. Methods The study covered 863 students from 41 classes of four schools. The optimization and feasibility of access to schools, recruitment strategies, intervention, and assessment procedures were examined. The course and content of the educational unit were evaluated with a mixed-methods approach. A pre-post measurement design was tested for the vaccination rate in all schools. Additionally, at two schools, improvement in vaccination-related knowledge and perceived self-efficacy were measured by questionnaire pre-educational unit (n=287) and post-educational unit (n=293). The remaining two schools provided only postintervention data. Finally, we evaluated the psychometric properties (i.e., reliability, retest reliability, and change rates) of the questionnaire, applying Cronbach’s alpha, factor analyses, generalized estimating equations and linear mixed models. Results The findings of the pilot study indicated good feasibility. Of the total sample, 437 students (50.9%) brought their vaccination cards to school, 68 students received Tdap-IPV vaccinations, and 11 received MMR vaccinations. Out of six knowledge questions, on average, the students had M=2.84 (95% CI [2.69, 3.10]) correct answers before and M=4.45 (95% CI [4.26, 4.64]) after the class. Ranging from 1 to 4, the self-efficacy scale changed by 0.3 points (p <.001); Cronbach’s alpha was 0.67 and 0.76 pre- and post-educational unit, respectively, and a one-factor solution was found. Content analysis of the five semistructured group interviews (n=12, 58.3% female) showed that all students found the length of the intervention to be appropriate. The teaching methods, including interactive and social media components, were perceived as very good. Conclusions A school-based educational and on-site vaccination intervention appears to be feasible in terms of procedures and the adequacy of the instruments for the adolescent target group. Trial registration ISRCTN, ISRCTN18026662. Pilot study for main trial registered 8 December 2017.

IntroductionChildhood vaccination programmes have been established in all Organisation for Economic Co-operation and Development (OECD) countries; however, measles, mumps and rubella (MMR) as well as diphtheria, tetanus, pertussis and polio (Tdap-IPV) vaccination rates are not optimal in adolescents. Education in combination with easy access vaccination may be a promising approach to improve vaccination rates. We aim at improving MMR and Tdap-IPV rates in a school setting in the context of a planned cluster randomised controlled trial (cRCT), the present paper describes the detailed protocol of this trial.Methods and analysisWe will conduct a school-based cRCT, where schools will be randomised to either an educational condition addressing knowledge, risk communication and enhancing self-efficacy regarding vaccination or a low-intensity information condition. In both conditions, a bus equipped with medical staff and materials, will be delivering MMR and Tdap-IPV vaccine directly after the intervention. Schools in the city centre of Berlin, Germany, will be stratified by percentage of migration and type of school. Primary outcome is the number of students who receive vaccination in the bus. Secondary outcomes are knowledge and self-efficacy. An estimated sample size of 355 school classes with approximately 25 students per class is required. The planned analyses will take the nested structure of students, classes and schools into account.Ethics and disseminationThe study will be performed according to the principles of Good Clinical Practice and the Declaration of Helsinki. Approval was obtained by the local ethics committee. Parents of all students will be informed in advance. Their written consent will be obtained, in case students are underage. For dissemination, we will engage with governmental organisations to create potential of our educational unit to be included in future public health prevention schemes.Trial registration numberISRCTN18026662;Pre-results.

ABSTRACT Objective: To evaluate the psychometric properties in terms of validity and reliability of the scale Self-efficacy and their child's level of asthma control: Brazilian version. Method: Methodological study in which 216 parents/guardians of children with asthma participated. A construct validation (factor analysis and test of hypothesis by comparison of contrasted groups) and an analysis of reliability in terms of homogeneity (Cronbach's alpha) and stability (test-retest) were carried out. Results: Exploratory factor analysis proved suitable for the Brazilian version of the scale (Kaiser-Meyer-Olkim index of 0.879 and Bartlett's sphericity with p < 0.001). The correlation matrix in factor analysis suggested the removal of item 7 from the scale. Cronbach's alpha of the final scale, with 16 items, was 0.92. Conclusion: The Brazilian version of Self-efficacy and their child's level of asthma control presented psychometric properties that confirmed its validity and reliability.

Abstract Background The aim of the present study was to evaluate the psychometric properties of the Persian version of delivery fear scale (DFS) among Iranian women population. Methods This is a methodological study that was conducted to evaluate the psychometric properties of DFS. Convenience sampling was used to select 200 pregnant women from the maternity ward of Razi Hospital in Ahvaz, Iran. In the first step, the scale was translated into Persian using backward-forward translation method. Afterwards, the following types of validity were examined: face validity based on impact score, construct validity based on confirmatory factor analysis (CFA), and concurrent validity. The Pearson correlation test was used to determine the correlation of DFS with pregnancy-related anxiety questionnaire (PRAQ), Childbirth Attitude Questionnaire (CAQ), Spielberger’s state-trait anxiety inventory (STAI), and the short form of Lowe’s childbirth self-efficacy inventory. Reliability of DFS was assessed by determining internal consistency (Cronbach’s alpha) and split-half method. Results CFA had satisfactory validity considering x2⁄df < 5 and the RMSEA < 0.08. /the obtained Cronbach’s alpha coefficient was 0.77. The split-half coefficient of the questionnaire was 0.83, indicating an acceptable reliability for the questionnaire. The results showed that DFS had a direct significant correlation with the CAQ (r = 0.72), PRAQ (r = 0.74), STAI-Y1 (r = 0.71) and STAI-Y1 (r = 0.63) and a reverse significant correlation with subscales of the short form of Lowe’s childbirth self-efficacy inventory including outcome expectancy (r= -0.75) and self-efficacy expectancy (r= -0.76). Conclusions The findings of the present study confirm the validity and reliability of the Persian version of DFS as an instrument for measuring fear of childbirth (FOC) in Iranian women population.

Background Iranian researchers have investigated breastfeeding self-efficacy and its related factors. However, there is no valid and reliable tool for assessing the breastfeeding self-efficacy of Iranian Farsi-speaking women. Research aim To examine the validity and reliability of the Breastfeeding Self-Efficacy Scale—Short Form among Iranian Farsi-speaking mothers. Methods We conducted this cross-sectional study at Izadi teaching hospital in Qom, Iran. Using convenience sampling, we recruited 174 mothers, who completed the questionnaire on the first postnatal day. A forward–backward translation method was used to translate the scale. Cronbach’s alpha and item-total characteristics were examined to test reliability. Construct validity was evaluated via principal component analysis (PCA), as well as known-groups validity. Results The mean (standard deviation) of sample age was 28.33 (5.38). The mean (standard deviation) of breastfeeding self-efficacy score was 54.32 (10.50), ranging from 24–70. Cronbach’s alpha (.92), inter-item correlations (.21–.72), and corrected item-total correlations (.44–.75) indicated the adequate reliability of the scale. PCA yielded one component with an eigenvalue of 6.97, explaining 49.8% of the total variance. There was no significant difference in the self-efficacy scores between primiparous and multiparous women. Breastfeeding self-efficacy was not significantly different between the groups in terms of the demographic characteristics. Conclusion The Farsi version of the Breastfeeding Self-efficacy Scale—Short Form is a valid and reliable instrument for Iranian Farsi-speaking mothers, with sound psychometric properties per the other studies worldwide.

Abstract Background Clinical experience is a crucial activity for nursing students. The way students` perceive clinical placement exerts an immense influence on the learning process. This study aims to test the psychometric properties of a 19-item version of the Clinical Learning Environment Inventory under Polish clinical conditions. Method For this study, Discriminant validity and Cronbach’s alpha reliabilities were computed. In order to measure content validity, the criterion validity Generalized Self Efficacy Scale and the Life Orientation Test - Revised were used. Results Cronbach’s Alpha for the Clinical Facilitator Support of Learning Scale and the Satisfaction with Clinical Placement scale is 0.949 and 0.901, respectively. The Spearman’s rank correlation coefficient indicates the existence of a positive correlation between the students’ satisfaction with clinical placement and their [overall] life optimism. Age correlates negatively with perceived teacher support and positively with satisfaction with clinical placement. The sense of self-efficacy correlates negatively with their satisfaction with clinical placement. Clinical Learning Environment Inventory − 19 could be a useful tool to evaluate the quality of the clinical learning process in Polish conditions.

Abstract Background Antiretroviral therapy (ART) has the most effective treatment for people with HIV, but its effectiveness depends on the individual medication adherence. Morisky Medication Adherence Scale (MMAS-8) is one of the most widely used scales to assess patient adherence. Thus, we aimed to validate a Portuguese version of MMAS-8 and determine its psychometric properties in HIV positive patients. Methods A cross-sectional survey was conducted in Centro Hospitalar Universitário São João (Porto, northern Portugal) at the infectious diseases department. After authorization to use the scale - granted by the author - and, a standard forward-backwards procedure to translate MMAS-8 to Portuguese, the questionnaire was applied to 233 patients with HIV doing ART. Reliability was assessed using Cronbach's alpha and test-retest reliability. Three levels of adherence were considered: 0 to &lt; 6 (low), 6 to &lt; 8 (medium), 8 (high). Results In the studied sample, the mean age was 45.03 years (SD = 11.63), 80.3% men, 19.3% women and 1 transgender, and 53.8% had ≤9 years of education. The mean number of prescribed ART per patient was 1.76. The mean score for the medication adherence scale was 7.29 (SD = 6.74). For the reliability analysis, 12 patients were excluded due to missing data (n = 221). Regarding the level of adherence, 22.5% were low adhering, 71.6% medium and 5.9% high. Corrected item-total correlations showed that 1 item does not correlate very well with the overall scale and was dropped. Scale reliability analysis for the remaining 7 items revealed an overall Cronbach's alpha of 0.661. Women had a protective effect on adherence (OR = 0.31;95%CI:0.15-0.66). Number of years doing ART, age of participants, and type of residence didn't show to be correlated with adherence. Conclusions MMAS-8 is a reliable and valid measure to detect patients at risk of non-adherence. A satisfactory Cronbach's alfa (0.661) was obtained. In general, adherence to medication was medium or high. Key messages This scale can be applied nationwide in other different hospitals, as it could serve as a tool for measuring adherence to ART that can allow for better health care to the ones that are low adhering. A Portuguese version of the MMAS-8 was created for measuring adherence to ART that maintained a similar structure to the original MMAS-8 and good psychometric properties.

The purpose of this study was to evaluate the psychometric properties of the Brazilian Scale for the Assessment of Self-Care Behaviors with Arteriovenous Fistula in Hemodialysis. Cross-sectional validation study, followed the recommendation provided by Sousa and Rojjanasrirat. Content validity, explanatory and confirmatory factor analyses used to check validity and Cronbach’s alpha was the reliability measure. Three hundred hemodialysis patients with arteriovenous fistula were included in the study. The expert committee assessed the content validity. Exploratory factor analysis confirmed the same two-factor structure found for the original scale, explaining 60.10% of the variance. Such solution was checked by confirmatory factor analysis with Cronbach’s alpha equal to 0.920, 0.810, and 0.884 for the overall scale, the self-care in management of signs and symptoms and the self-care in prevention of complications subscales respectively. The scale has good psychometric properties to assess self-care behaviors and can be used with Brazilian patients on hemodialysis with arteriovenous fistula.

Multigroup Ethnic Identity Measure

The current study examined psychometric properties of the Japanese version of Abbreviated Multidimensional Acculturation Scale (AMAS-ZABB-JP) and the 20-item Multigroup Ethnic Identity Measure (MEIM-JP) with 273 Japanese sojourners and immigrants to the United States. The theoretical six-factor structure for the AMAS-JP and two-factor structure for the MEIM-JP was consistent with the literature. The subscales of the AMAS and MEIM showed expected patterns of correlation with each other and with additional variables (i.e., number of years in the United States), providing evidence for construct validity. Cronbach’s alpha reflected high levels of reliability for both scales. Despite strong psychometric findings, there were translational and cultural-based findings that suggest the need for further research.
