Abstract Background Animal breeders' inadequate awareness about the transmission of brucellosis and their improper knowledge about prevention of brucellosis are among important barriers to vaccinate animals against brucellosis. The aim of this study is design, implementation and evaluation of a theory-driven and vaccination-focused training program for brucellosis prevention.Methods In this exploratory psychometric study, a brucellosis prevention questionnaire (BPQ) was developed. Face-to-face interviews were conducted to develop the initial items of BPQ. The findings from interviews were merged with those of literature review. Face, content and construct validity of BPQ were assessed by participation of animal breeders, veterinarians and health educationists. Impact Score (IS), Content Validity Ratio (CVR) and Content Validity Index (CVI) of the items were calculated. Construct validity of BPQ was evaluated through factor analyses. Cronbach’s alpha, Intra-class correlation coefficient (ICC), composite reliability and standard error of measurement (SEM) were measured to assess the reliability of the findings by BPQ.Results BPQ was finalized by 53 items. Its validity was confirmed by CVI, CVR, and IS of 0.90, 0.74 and 4.30, respectively. The items were loaded into three constructs of awareness, attitude and practice. The predictive power of the awareness, attitude and practice was 43.43%, 15.81% and 15.78%, respectively. The fitness of the proposed model among those constructs was confirmed by RMSEA < 0.08, Normed Chi2 < 5, CFI > .90, TLI > .90.Conclusion The brucellosis prevention questionnaire has acceptable psychometric properties. Applying BPQ, veterinarians and educational planners can identify factors influencing animal breeders' preventive behavior.

Modern lifestyle is associated with prolonged exposure to sedentary behavior (SB), especially in older adults; however, there is a lack of validated questionnaires to measure SB in Brazilian older adults. The aim of this study was to adapt and validate the Brazilian version of the “Measure of Older Adults Sedentary Time” (MOST) questionnaire in Brazilian older adults. Content validity, clarity and concurrent validity of the adapted MOST were examined. Fifty-seven participants (68.7 ± 3.47 years) answered the adapted version of the MOST questionnaire and wore an ActiGraph wGT3X-BT accelerometer for seven days. After this period, participants answered the adapted MOST again and the accelerometer was collected. MOST answers were summed over for calculating self-reported time spent in SB. A cutoff point of < 100 counts/min was applied to accelerometer data for estimating time spent in SB. The relationship between SB estimates from MOST and accelerometer was verified by Pearson correlation, reproducibility was verified by intra-class correlation coefficient (ICC), internal consistency by Cronbach’s alpha (α) and concordance by Bland Altman. Significance was set at P <0.05. Content validity index and clarity index were 100% and 98%, respectively. ICC was 0.72 (95% CI: 0.56-0.82) for total time in SB assessed with the MOST questionnaire. The correlation between SB estimates from MOST and accelerometer data was 0.37 (95% CI: 0.130.58). The adapted MOST systematically underestimated SB compared to accelerometer (measurement bias: -732.8 min/week [2087.6; -3553.2 min/wk]). The adapted MOST questionnaire presents adequate validity for assessing SB in the Brazilian older adults.

BACKGROUND: The structure of buildings is in degradation over time, monitoring their safety status and providing timely warnings is crucial. Therefore, an efficient visual inspection of the building’s safety has intrinsic value to give early warnings to owners and managers. OBJECTIVE: This study aimed to provide an audit tool for evaluation of the administrative in-operation buildings’ safety status. METHODS: Factors affecting the administrative buildings’ safety status was determined based on the National Building Regulations of Iran (NBRI) and other studies. checklist items and their guidelines were prepared. Face validity (quantitative and qualitative), content validity ratio (CVR), and content validity index (CVI) were calculated for the checklist. The Intra-class correlation coefficient (ICC) used for inter-rater reliability and Cronbach’s α was used to evaluate internal consistency of the checklist. RESULTS: Forty-seven items related to in-operation building safety were extracted from literature review. Based on the results of the psychometric analysis, 5 items were removed and 42 items remained. The values of different psychometric indices for the other items indicated their acceptable validity. (α= 0.82, ICC≥0.75). CONCLUSION: The designed checklist had a good level of validity and reliability for inspecting architectural, technical services, and managerial safety aspects of administrative in-operation buildings. Stakeholders can use it for quick and comprehensive assessment of building safety. Use of this checklist are expected to give early warnings about the safety of buildings to the stakeholders.

AbstractObjectiveThe present study aimed to translate the English version of the Nutritional Form For the Elderly into Simplified Chinese, as well as to test the reliability (homogeneity and stability) and validity (content and construct validity) of the Chinese version of the Nutritional Form For the Elderly (NUFFE-CHI).DesignThe study adopted a cross-sectional design. The English version of the NUFFE was translated into Simplified Chinese and a questionnaire survey was conducted. The data were analysed with statistical methods to estimate the homogeneity, stability, content and construct validity.SettingJinzhou City, China.SubjectsA total number of 701 community-dwelling older adults answered the questionnaire, including background variables and the NUFFE-CHI. A small group of the participants (n 50) completed the NUFFE-CHI twice for test–retest reliability.ResultsCronbach’s α was 0·65 and the split-half reliability was 0·67. Item-to-total correlation analyses showed that the scale has sufficient internal consistency. The test–retest reliability regarding the total scores of NUFFE-CHI was reflected in an intra-class correlation coefficient of 0·88. The intra-class correlation coefficients between the test and retest of the NUFFE-CHI items varied between 0·43 and 0·98. A content validity index of 0·83 explained good content validity. Construct validity was demonstrated in an exploratory factor analysis with a six-factor solution, explaining 57·65 % of the variance.ConclusionsThis first testing of the NUFFE-CHI indicates sufficient evidence for reliability, content and construct validity. Further testing studies regarding homogeneity, concurrent validity, sensitivity and specificity are required before the NUFFE-CHI can be used as a screening instrument in clinical settings and in research.

AbstractThe present study was conducted to translate and assess the validation of the measure of self-management of type 1 diabetes for adolescents that developed by Schilling et al [Schilling LS, Knafl KA, Grey M. Changing patterns of self-management in youth with type I diabetes. J Pediatr Nurs 2006;21:412–24].The first stage of the study involved the translation of the measure of self-management of type 1 diabetes for adolescents into Persian based on the model proposed by Wild et al. in two versions [Wild D, Grove A, Martin M, Eremenco S, McElroy S, et al. Principles of good practice for the translation and cultural adaptation process for patient-reported outcomes (PRO) measures: report of the ISPOR task force for translation and cultural adaptation. Value Health 2005;8:94–104; Wild D, Eremenco S, Mear I, Martin M, Houchin C, et al. Multinational trials – recommendations on the translations required, approaches to using the same language in different countries, and the approaches to support pooling the data: the ISPOR patient-reported outcomes translation and linguistic validation good research practices task force report. Value Health 2009;12:430–40]. The translated versions were reviewed in consultation sessions with experts and the more appropriate items were selected and the final version was translated back into English in two versions and was then sent to the measure’s designer for confirmation. The content validity of the measure was then evaluated by a group of experts and found to be acceptable. The next stage evaluated the measure’s construct validity. This measure contains 52 items classified under five subscales. The confirmatory factor analysis was performed to assess the measure’s construct validity and was found to be acceptable. For evaluating the reliability of the measure, its internal consistency was assessed through calculating its Cronbach’s alpha and intra-class correlation. The measure’s consistency was measured through calculating its test-retest reliability.The assessment of the measure’s content validity revealed a content validity index of 0.98. For the construct validity of the measure using the confirmatory factor analysis, the following figures were obtained: NFI=0.97, RMSA=0.001, AGFI=0.81, IFI=0.833, GFI=0.83. In the assessment of the measure’s reliability, the intra-class correlation showed an overall Cronbach’s alpha of 0.88. The test-retest showed a consistency of 0.73 for the measure.The validation of the 48-item measure revealed that it can be used in the population of Iranian adolescents with type 1 diabetes (8 items changed their subscales and 4 items were removed).

Abstract Disc height has been a focus of research on disc degeneration and low back pain (LBP). However, choosing an appropriate method to quantify disc height remains controversial. The aim of the present study was to determine the reliability and construct validity of disc height quantification methods. Repeated semi-automatic measurements of L4–5 and L5–S1 discs were obtained from 43 T2-weighted mid-sagittal 3T magnetic resonance (MR) images of 22 subjects with LBP (43±13 years), blinded to prior measurements. Heights were calculated with area-based methods (using 60%, 80% and 100% of the disc width), and point-based methods (Hurxthal’s, Dabbs’ and combining the two). Intra-class correlation coefficients (ICC) and standard error of measurement (SEM) were estimated. Construct validity was assessed using correlation coefficients. Intra-rater ICC(3,1) of the area-based disc height measurements ranged from 0.84 to 0.99 with an inter-rater ICC(2,1) of 0.99. Measurements with point-based methods had lower intra- and inter-rater reliability ranging between 0.76 and 0.96 and between 0.84 and 0.98, respectively. Inter-rater SEM varied between 0.2 and 0.3 mm for area-based methods and between 0.3 and 0.7 mm for point-based methods. Excluding Dabbs’, high correlations (r>0.9) were observed between methods. Area-based height measurements using partial disc width demonstrated excellent reliability and construct validity and outperformed point-based methods.

IntroductionUltrasound imaging (USI) is useful to evaluate structures of the foot to guide treatment, but the reliability of USI technique needs to be clarified. The goal of the study was to evaluate the intra- and inter-examiner reliability of USI image capture, and measurement of the cross-sectional area (CSA) and thickness of the flexor hallucis longus (FHL) for experienced and novice examinersMaterial and methodsFHL images were captured for 20 healthy adults. Reliability of image capture was evaluated between images repeated at 10-min interval for an experienced and a novice examiner. Reliability of image-based measurements was evaluated for one experienced and one novice rater, using all images. The intra-class correlation coefficient (ICC) and the standard error of measurement (SEM) were calculatedResultsIntra-examiner reliability of image capture for the FHL muscle examined by USI was excellent for both thickness (ICC3,1, 0.944–0.976; SEM, 6.8%–10.0%) and CSA (ICC3,1, 0.954–0.979; SEM, 10.8%–16.5%), with no effect of examiner experience. Reliability was also excellent for measurement of thickness (ICC3,1, 0.954–0.972; SEM, 1.2%–9.6%) and CSA (ICC3,1, 0.961–0.986; SEM, 9.2%–14.1%), with no effects of experience.ConclusionsReliability of image capture and image-based measurements developed by USI of CSA and thickness for the FHL muscle in healthy individuals was excellent, independent of the examiner experience.
