The purpose of this study was to validate the six-item Men’s Osteoporosis Knowledge Quiz (MOKQ). The MOKQ asks questions about risk factors that are pertinent to men, such as the risk for developing low bone mass related to hormone treatment for prostate cancer and the importance of testosterone for bone mass. A survey was sent to 242 men with a mean age of 83.2 years. The mean number of questions answered correctly in response to the six-item MOKQ was 2.37. Convergent validity was examined by correlating the score achieved on the MOKQ with the score achieved on the total Facts on Osteoporosis Quiz. The Pearson correlation coefficient for the MOKQ and the Facts on Osteoporosis Quiz was r = .76. Reliability was demonstrated by computing a Cronbach’s alpha for the MOKQ ( r = .72). The MOKQ was found to have adequate reliability and validity in assessing older men’s knowledge about osteoporosis.

Abstract Background: Cognitive disorders are one of the most important issues in old age. They may remain hidden in the early stages. There are many cognitive tests, but some variables affect their results (e.g., age and education.) This study aimed to evaluate the reliability and validity of A Quick Test of Cognitive Speed (AQT) in Iranian older adults.Methods: This study aimed to test the psychometric properties of AQT. 114 older adults participated in the study and were divided into three groups (46 with mild cognitive impairments (MCI), 24 with dementia, and 45 without MCI and dementia) based on the diagnosis of two geriatric psychiatrists. Participants were assessed by AQT and Mini-Mental State Examination (MMSE). Data were analyzed using Pearson correlation, independent t-test, and ROC curve by SPSS v.23.Results: There was no significant correlation between AQT subscales and age and no significant difference between the AQT subscales in male and female, educational levels, and marital status. The test-retest correlations (r) were significant for Color (C) 0.84, Form (F) 0.91 and Color-Form (CF) 0.94. Convergent validity was significant between MMSE and AQT. Its correlation was with Color -0.78, Form -0.71, and Color-Form -0.72. The cut-off point for Color was 43.50 s, Form 52 s, and Color-Form 89 s were based on sensitivity and specificity for differentiating older patients with MCI with controls. The cut-off point for Color was 62.50 s, for Form 111 s, and Color-Form 197.50 s based on sensitivity and specificity measures for differentiating older patients with dementia and MCI.Conclusion: The findings of this study showed that A Quick Test of Cognitive Speed (AQT) is a suitable tool for assessing cognitive function in older adults.

Abstract Background: The PROMIS Preference score (PROPr) is a new generic preference-based health-related quality of life (HRQoL) score that can be used as a health state utility (HSU) score for quality-adjusted life years (QALYs) in cost-utility analyses (CUAs). It is the first HSU score based on item response theory (IRT) and has favorable psychometric properties. The PROPr combines the seven PROMIS domains: cognition, depression, fatigue, pain, physical function, sleep disturbance, and ability to participate in social roles and activities. It was developed based on preferences of the US general population. We aimed to validate the PROPr in a patient sample and to compare it to the EQ-5D. Methods: We collected PROPr and EQ-5D-5L data from 141 patients treated in the rheumatology and psychosomatic departments. We evaluated the convergent validity, reliability, known-groups construct validity, and ceiling and floor effects of the PROPr and compared those characteristics to those of the EQ-5D. Results: The mean PROPr (0.26, 95% CI: 0.23; 0.29) and the mean EQ-5D (0.44, 95% CI: 0.38; 0.51) differed significantly (d = 0.18, p < 0.001). The Pearson correlation coefficient between the two scores was r = 0.72. The PROPr and EQ-5D demonstrated high reliability and similar discrimination power across sex, age, and conditions. While the PROPr showed a floor effect, the EQ-5D showed a ceiling effect. Conclusion: PROPr and EQ-5D measure HSU differently. The PROPr shows a broader definition of perfect health, with a wider range of measurements at the top end. The previous results of excellent validity and precision were confirmed.

ABSTRACT Objectives The 6-minute stepper test (6MST) is a submaximal test that requires little space to assess exercise capacity compared to the 6-minute walk test (6MWT). The study aims to investigate the test-retest reliability and convergent validity of 6MST and to compare physiological responses, dyspnea, fatigue perception with 6MST and 6MWT in patients with ankylosing spondylitis (AS). Methods To test the convergent validity of 6MST, 65 patients performed both 6MWT and 6MST on the first day and correlation between two tests were assessed with Pearson correlation test. In order to investigate the test-retest reliability of the 6MST, thirty-two of the 65 patients performed 6MST one week later and intraclass correlation coefficients (ICC) were calculated. Dyspnea and fatigue perception were analyzed with using Wilcoxon signed-rank test, physiological responses were analyzed using paired sample t-test. Results Excellent test-retest reliability was observed for 6MST (ICC: 0.988). There was a significant correlation between 6MST and 6MWT (r: 0.725, p&lt;0.001). Dyspnea and leg fatigue perception were significantly higher in 6MST (p&lt;0.05). Physiological responses and fatigue perception were similar in both 6MST and 6MWT (p&gt;0.05). Conclusion This study demonstrated that the 6MST is reliable and valid method to evaluate exercise capacity in patients with AS. 6MST can be used to evaluate exercise capacity of patients with AS.

Background: Organizations usually seek for decreasing problems such as slacking and aggression and increase the behaviors that lead to a benefit such as productivity for the organization. One of the factors creating productivity in the organization is organizational citizenship behavior. Therefore, this research is aimed at investigating the relationship between organizational citizenship behavior and human resources productivity in the selected hospitals of ShahidSadoughi University of Medical Sciences in Yazd, 2018. Methods: This research is a descriptive correlation study. The population includes the staff of three selected hospitals in Yazd. Out of the mentioned population, 211 people were selected by random sampling. Data collection tool was a standard questionnaire. Reliability and validity of the tool have been already approved in a similar study. The questionnaire consists of two parts including: organizational citizenship behavior, , and human resources productivity. Data analysis was done by Pearson correlation, regression, t-test, and analysis of variance in SPSS16. Results: The mean total scores of organizational citizenship behavior and human resources productivity were 3.06 ± 0.32 and 3.50 ± 0.62, respectively. The investigation of the mean scores of organizational citizenship behavior in each aspect indicated that the highest mean score, 4.11 ± 0.54, belonged to altruism and the lowest, 1.58 ± 0.75, belonged to sportsmanship. Among the various aspects of human resources productivity, the highest mean score was for competency, 3.89 ± 0.55, and the lowest was obtained for support, 3.22 ± 0.57. Based on the employees’ perspectives, there was a positive and significant relationship between OCB and human resources productivity (P-value < 0.001 and r = 0.297). Conclusion: OCBhas a direct effect on resources productivity based on the staff viewpoints in educational hospitals. So, providing the opportunity of promotion of organizational citizenship behaviors can be an effective factor in increasing human resources productivity.

Psychometric testing of the Shared Vision (SV) scale that measures team efforts toward common patient-centered goals was initially estimated among rural hospital nurse executives. The purpose of this study was to estimate the scale’s reliability (internal consistency), convergent validity (Pearson correlation with Practice Environment Scale), and structural validity (ordinal confirmatory factor analysis) among acute care Magnet® hospital nurses. The study sample included 289 nurses from 27 acute care Magnet® hospitals. The scale demonstrated acceptable estimates for internal consistency (Cronbach’s α = .902, 95% confidence interval [CI] = [0.883, 0.919]), convergent validity ( r = .720, p < .001), and structural validity with a one-factor structure. The findings of this study supported the reliability and validity of the SV scale as a unidimensional construct in measuring SV among nurses in acute care Magnet® hospitals. Further testing among different nursing providers and health care settings is needed to accumulate evidence and expand use of the instrument.

Background:There are several studies assessing bone mass and osteoporosis (OP) development of patients with giant cell arteritis (GCA) during glucocorticoid treatment, however data at time of diagnosis is scarce.Objectives:To analyze bone metabolism, bone mineral density (BMD) and trabecular microarchitecture by measuring trabecular bone score (TBS) in patients with recent diagnosis of GCA.Methods:Retrospective observational study in which we included all patients with GCA and bone metabolism assessment at diagnosis. We recorded: risk factors for OP (previous fractures and anti-OP treatments), bone metabolism (calcium, phosphate, PTH, 25-vitaminD [25-OHD]) and the DXA results (Lunar, DPX) at the time of diagnosis and during the follow-up. The statistic analysis was made with SPSS.Results:36 patients (27 W: 9M) with a mean age of 76±9 years were included. The clinical characteristics of the GCA at diagnoses were: headache (81%), constitutional syndrome (58%), allodynia (42%), visual loss (42%, binocular in 2 patients), jaw claudication (39%), polymyalgic syndrome (28%), amaurosis fugax (25%) and lingular necrosis (n=1, 3%). Additional diagnosis tests included: temporal biopsy (86%, being pathologic in 55%), temporal ultrasound (97%, pathologic 34%), extra-cranial arteries ultrasound (81%, pathologic 7%) and PET/CT (19%, pathologic 86%). Up to 61% received three metilprednisolone bolus (mean dose 1700mg). 7 patients (19%) had previous OP and 3 had already suffered a fragility fracture (Colles, vertebral and femur). Only 4 patients were receiving anti-OP treatment (2 oral bisphosphonate, 2 zoledronate).At time of diagnosis of GCA, the mean of 25OHD was 17±13ng/mL (88%, <30). BMD showed low bone mass in 80% of patients (47% with OP, 33% osteopenia). The mean TBS was 1.026±0.098 and up to 38% showed poor bone microarchitecture [values <1.23]). No significant differences were observed between patients with or without TBS <1.23. Up to 94% of patients received anti-OP treatment (26 zoledronate, 6 oral bisphosphonate, 1 denosumab, 1 teriparatide). 3 patients had incidental fractures during the follow-up, however no relation was found with BMD or TBS.Conclusion:Low bone mass and vitamin D insufficiency are frequent in patients with recent diagnoses of GCA and up to 38% have poor bone microarchitecture at baseline. Thus, it’s important to perform a bone mass assessment in all patients with recent diagnose of ACG and initiate therapeutic or preventive anti-OP treatment if required.Disclosure of Interests:None declared

Abstract Background Juvenile idiopathic arthritis (JIA) may seriously affects patients’ quality of life (QoL), but it was rarely focused and studied in China, so we explore JIA children’s QoL using Chinese version of the PedsQL4.0 Generic Core and PedsQL3.0 Rheumatology Module scale, and analyzed the psychometric properties of these two Scales among Chinese JIA children. Methods We recruited 180 JIA patients from Children's Hospital Affiliated to Capital Institute of Pediatrics and Hebei Yanda Hospital from July 2018 to August 2019. The questionnaires include information related on JIA, PedsQL4.0 generic core and PedsQL3.0 Rheumatology Module scales. According to the disease type, onset age of and course of JIA, we divided them into different groups, then compared the QoL status among different groups. Moreover, we analyzed the reliability and validity of these two scales in these 180 JIA children. Results The mean score of PedsQL4.0 generic core scale on these 180 patients was 82.85 ± 14.82, for these in active period was 72.05 ± 15.29, in remission period was 89.77 ± 9.23; the QoL score of systemic, polyarticular and oligoarticular JIA patients were 77.05 ± 19.11, 84.33 ± 12.46 and 87.12 ± 10.23. The mean score of PedsQL3.0 Rheumatology Module scale on 180 patients was 91.22 ± 9.45, for these in active period was 84.70 ± 11.37, in remission period was 95.43 ± 4.48; the QoL score of systemic, polyarticular and oligoarticular JIA patients were 89.41 ± 11.54, 89.38 ± 10.08 and 93.71 ± 6.92. In the PedsQL 4.0 Generic Core scale, the α coefficients of total scale and almost every dimension are all greater than 0.8 except for the school activity dimension of 0.589; the correlation coefficients of 22 items’ scores (total 23 items) with the scores of dimensions they belong to are greater than 0.5 (maximum value is 0.864), and the other one is 0.406. In PedsQL3.0 Rheumatology Module scale, except for the treatment and worry dimensions of 0.652 and 0.635, the α coefficients of other dimensions and the total scale are all greater than 0.7; the correlation coefficients of all items’ score were greater than 0.5 (the maximum is 0.933, the minimum is 0.515). Conclusions The QoL of Chinese JIA children is worse than their healthy peers, these in active period and diagnosed as systemic type were undergoing worst quality of life. The reliability and validity of PedsQL 4.0 Generic Core and PedsQL3.0 Rheumatology Module scale in Chinese JIA children are satisfactory, and can be used in clinical and scientific researches.
