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.

Introduction: The objective of this study was to adapt the Brazilian version, and verify the validity, reliability and internal consistency of the Oliveira questionnaire on low back pain in young people.Material and Methods: The questionnaire was translated from European Portuguese into Brazilian Portuguese by means of translation and re-translation. The validity of the contents was determined by experts who analyzed the clarity and pertinence of the questions. Fifteen young people aged 15 to 18 took part in the pre-test step (qualitative analysis), 40 in the test-retest (reliability) and 679 in the evaluation of internal consistency. The intra-class correlation coefficient and Spearman’s correlation coefficient were used in the reliability analysis (test-retest), and Cronbach’s alpha to determine the internal consistency (stability).Results: In the translation phase the questionnaire was modified and considered suitable, observing similarity and equivalence of the two versions. After being corrected by the experts in the validation of the contents, the instrument was considered suitable and valid, and in the pre-test, the young people suggested some modifications to make the questionnaire more succinct. With respect to reliability, the values for the intra-class correlation coefficient were between 0.512 – acceptable and 1 – excellent and Spearman’s correlation coefficient varied between 0.525 and 1, classifying the instrument as reproducible. The internal consistency was considered acceptable with a 0.757 Cronbach’s alpha.Discussion: The Oliveira questionnaire was choosen since it has been used in several Portuguese studies; moreover, it addresses the need to raise data regarding low back pain and associated risk factors.Conclusions: The Brazilian version of the Oliveira questionnaire on low back pain in young people showed valid and reliable cultural adaptation, with good reliability and stability.

Abstract Background Cross-table lateral (CL) radiography is a convenient and feasible method to assess cup version angle (VA) after total hip arthroplasty; However, pelvic tilt (PT) may contribute to its measurement inaccuracy. How PT affects CL radiographic measurements have not been well studied. We sought (1) to determine the effect of the PT on cup version measurement on CL radiography and (2) to develop a method for reducing measurement errors caused by the PT. Methods We used 3D technique to construct standard model and capture CL radiography simulation. A linear regression model was created to analyze the relationship between PT and VA. CL radiography and computed tomography (CT) were performed for the enrolled patients after surgery. The consistency between CL and CT measurements were verified by intra-class correlation coefficient (ICC). Results There was a high correlation between the VA and PT. For each 1-degree increased in the PT, the VA decreased by 0.76° (R2 = 0.995, p < 0.001). Based on the data, we created a corrective formula to convert the radiographic measurements into values approximating the actual VA under a natural pelvic position. The VA measurements corrected by our equation was in high agreement with the CT-measured values with reference to the corresponding PT (ICC = 0.988, p < 0.001), which was in sharp contrast to that without PT control (ICC = 0.454, p = 0.203). Conclusions The PT may contribute to cup version measurement inaccuracies on CL radiography. Our mathematical algorithm can serve as a reliable method to improve the accuracy of CL radiography.

Family care givers providing a major portion of care giving often experience stress related to the negative consequences for their health. Female care givers often more heavily involved care giving activities than males. Care givers’ gender studies have seldom conducted in Taiwan. The purpose of this study was to explore the relationship of demographic factors and coping on health of female care givers of older adults with dementia in Taiwan. In addition, whether coping mediated or moderated the relationship between stress and care giver’s health was also examined. Lazarus and Folkman’s Stress model guided this study. Using a secondary data analysis method, this study examined data collected from the family care givers of older adults with dementia (2002). One hundred and three female care givers were analyzed by applying Pearson correlation, simple and multiple regression analysis. The findings showed care givers who are younger, more income, and with helpers had better health. Care givers who had less income, without helpers, and caring for care recipients with more behavioral problems had more depressive symptoms. In addition, mediating effect of avoidance coping was supported in this study. The data analysis from this study will provide a basis for nurses to develop interventions that minimize the negative impacts on female care givers.

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.

The Relationship

The relationship of objectively measured sedentary time (ST), frequency of breaks in ST, and lower extremity function (LEF) was investigated in a diverse sample aged ≥ 70 years (n = 217). Physical activity (PA) was assessed by accelerometry deriving moderate-vigorous PA (MVPA) minutes per registered hour (MVPA min · hr−1), registered ST (ST min · hr−1), and breaks in ST min · hr−1 (breaks · hr−1). LEF was assessed by the Short Physical Performance Battery. Univariate associations with overall LEF were MVPA (r = .523), ST (r = −.499), and breaks (r = .389). Adjusted linear regression including MVPA min · hr−1, ST min · hr−1, and breaks · hr−1 explained 41.5% of LEF variance. Each additional break · hr−1 was associated with 0.58 point increase in LEF. Breaks and MVPA had strongest independent associations with LEF. Promoting regular breaks might be useful in maintaining or increasing LEF and later life independence. This novel finding is important for the design of effective lifestyle interventions targeting older adults.

Abstract Purpose (main purposes and research question) The purpose of this study is to assess the accuracy and precision of the smartphone with application and casing (Scolioscreen) compared to the Scoliometer. Methods The Axial Trunk Rotation (ATR) was measured in adolescent scoliosis patients visiting the outpatient clinic while performing the Adam Forward Bending Test. The Scolioscreen measurements were performed by the orthopedic surgeon and a parent. They were compared to the measurement with the Scoliometer by the orthopedic surgeon, the gold standard. The accuracy was determined with the Pearson’s correlation coefficient, and precision was determined by assessing the intra- and inter-variability with the intra-class correlation coefficient (ICC). Results Fifty patients with adolescent idiopathic scoliosis (44 girls) were included with a mean age of 14.1 years and a mean Cobb angle of 38.5°. The accuracy of both the parents and orthopedic surgeon was excellent with a Pearson correlation coefficient of 0.92 and 0.97, respectively. All the ICC’s, both intra- and inter-observer, were over 0.92 demonstrating excellent precision. Conclusion This study confirms the accuracy and precision of the Scolioscreen when measuring the ATR on patients with AIS. Therefore, the Scoliometer can be replaced by the more easily available Scolioscreen which can be used by both physician and parents.

The Relationship

The objectives were to clarify whether the relationship between physical performance and frailty was independently and jointly mediated by movement behaviors and body composition. We analyzed 871 older adults (476 women) from The Toledo Study for Healthy Aging. Skeletal muscle index (SMI) and fat index (FI) were determined using bone densitometry. Sedentary time (ST) and moderate-to-vigorous physical activity (MVPA) were assessed using accelerometry. The Frailty Trait Scale and The Short Physical Performance Battery (SPPB) were used to evaluate frailty and physical performance, respectively. Simple and multiple mediation analyses were carried out to determine the role of movement behaviors and body composition, adjusted for potential confounders. ST and MVPA acted independently as mediators in the relationship between SPPB and frailty (0.06% for ST and 16.89% for MVPA). FI also acted as an independent mediator in the same relationship (36.47%), while the mediation role of SMI was not significant. MVPA and FI both acted jointly as mediators in this previous relationship explaining 58.15% of the model. Our data support the fact that interventions should simultaneously encourage the promotion of MVPA and strategies to decrease the FI in order to prevent or treat frailty through physical performance improvement.

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.

Objectives: Loneliness is a significant concern among the elderly and requires measurement and intervention. This study was conducted to translate and make a psychometric evaluation of the 6-item de Jong Gierveld loneliness scale in Iranian older people. Methods & Materials: This is a descriptive study carried out in 2018. After receiving permission from the tool designer, the original version of the 6-item de Jong Gierveld loneliness scale was translated into Persian by the translation and translation-back method. Then its face and content validities were determined. The final Persian version was completed by 224 eligible elderly residents in Khorramabad City, Iran. The data were analyzed using Confirmatory Factor Analysis (CFA), the Pearson correlation coefficient, the Intra-class Correlation Coefficient (ICC), and the Cronbach alpha. The SPSS and AMOS were used, and the significance was determined at the level of P≤ 0.05. Results: The Persian version of the 6-item de Jong Gierveld Loneliness Scale had an acceptable content validity (CVI=0.874). Confirmative factor analysis indicated the extraction of two factors: emotional loneliness and social loneliness (CMIN/DF=1.48, GFI=0.983, IFI=0.983, RMSEA=0.004). The overall loneliness score showed a significant correlation with the hospital anxiety and depression scale. The reliability of the scale was accepted by the intra-class correlation coefficient and the Cronbach alpha coefficient. Conclusion: The Persian version of the 6-item de Jong Gierveld loneliness scale is a reliable and valid measure of loneliness in Iranian elders.
