Introduction: One of the popular questionnaires for screening neuropathic pain is the DN4 (Douleur Neuropathique 4) which has been translated into many languages and validated in different populations. So, we wanted to determine the Persian version of this questionnaire’s reliability and validity to differentiate neuropathic pain from other painful non-neuropathic conditions. Methods: This cross-sectional study was conducted on 120 patients who suffered from chronic pain referred to the Physical Medicine and Rehabilitation Department at the three great referral hospitals in Tehran, Iran in 2016. In this study, a modified version of DN4 was used to validate adding a question related to the appearance of pain in an especial joint and adding visual analogue scaling (VAS) score in each item. Results: The modified DN4 questionnaire had high reliability for assessing neuropathic pain with the Cronbach’s alpha coefficient of 0.874. The correlation coefficients obtained by the retest intra-class correlation test ranged from 0.650 to 0.941. Also, the internal consistency of Spearman’s R coefficients ranged from 0.482 to 0.904. Test-retest reliability analysis also showed a higher intraclass correlation (ICC) value in the neuropathic than non-neuropathic pain group (0.85 vs0.73). The modified DN4 questionnaire could effectively discriminate neuropathic pain from non-neuropathic pain with the area under the curve (ROC) of 0.989 (95% CI: 971–1000, P < 0.001). The best cutoff value for the modified DN4 questionnaire to diagnose neuropathic pain was 5, yielding a sensitivity of 98.3% and a specificity of 90.3%. Conclusion: Applying the new modified Persian version of DN4 achieved by adding a VAS score and a new question related to the appearance of pain in an especial joint led to high reliability and validity for this tool to discriminate neuropathic from non-neuropathic pain.

The current research aims to evaluate the reliability and validity of the Hindi Child Perception Questionnaire (CPQ11–14) in a child population of India. A randomly selected sample of children aged 11–14 years (n = 331) and their parents completed the Hindi translation of CPQ11–14 and the Parental-Caregiver Perceptions Questionnaire (P-CPQ), respectively, in this cross-sectional study. Children also provided a self-rating of oral health and were examined for dental caries. Exploratory Factor Analysis (EFA) was conducted to assess the dimensionality of the Hindi-CPQ11–14. Internal consistency and reliability on repeated administration were evaluated. Convergent and divergent validities were determined by estimating correlation coefficients between items and the hypothesised subscales. Concurrent validity was assessed using multiple linear regression analyses. The four factors extracted in EFA had a total variance of 38.5%, comprising 31 items. Cronbach’s alpha for the internal consistency of the overall scale was 0.90; reliability on repeated administration was 0.92. All the Hindi CPQ11–14 items had an item-hypothesised subscale correlation coefficient of ≥0.4, and these were greater than item-other hypothesised subscale correlations, demonstrating good convergent and divergent validities respectively. Hindi-CPQ11–14 was associated with self-ratings of the oral health and overall P-CPQ scores demonstrating good concurrent validity. Hindi-CPQ11–14 showed a factor structure different from the English CPQ11–14 and exhibited good validity and reliability.

The assessment of loading during walking and running has historically been limited to data collection in laboratory settings or with devices that require a computer connection. This study aims to determine if the loadsol®—a single sensor wireless insole—is a valid and reliable method of assessing force. Thirty (17 male and 13 female) recreationally active individuals were recruited for a two visit study where they walked (1.3 m/s) and ran (3.0 and 3.5 m/s) at a 0%, 10% incline, and 10% decline, with the visits approximately one week apart. Ground reaction force data was collected on an instrumented treadmill (1440 Hz) and with the loadsol® (100 Hz). Ten individuals completed the day 1 protocol with a newer 200 Hz loadsol®. Intraclass correlation coefficients (ICC3,k) were used to assess validity and reliability and Bland–Altman plots were generated to better understand loadsol® validity. Across conditions, the peak force ICCs ranged from 0.78 to 0.97, which increased to 0.84–0.99 with the 200 Hz insoles. Similarly, the loading rate ICCs improved from 0.61 to 0.97 to 0.80–0.96 and impulse improved from 0.61 to 0.97 to 0.90–0.97. The 200 Hz insoles may be needed for loading rate and impulse in running. For both walking and running, the loadsol® has excellent between-day reliability (>0.76).

Validity And Reliability

The usual fitness tests available to assess maximal oxygen uptake [Formula: see text] a key fitness component, are not particularly useful for epidemiological studies. Questionnaires to assess [Formula: see text] however, are simple, easy to use, and inexpensive. In 1986, Huet developed such a French general questionnaire, which now also has an English version. Its simplicity is interesting as it could be used to survey large populations. The purpose of this study was to assess the validity and reliability of this Huet questionnaire in a sample of healthy French volunteers. A total of 108 subjects were included in this study, 88 males and 20 females. The validity of the questionnaire was checked using correlation coefficients and a Bland-Altman plot between questionnaire estimations and measures of [Formula: see text] obtained with a stress test on a cycle ergometer. An intraclass correlation coefficient (ICC) was also calculated to determine the reliability of the questionnaire. Significant correlation was obtained with the Huet questionnaire and measured [Formula: see text] (r2 = 0.77, p = 0.0001, SEE = 5.97 ml•kg−1•min−1, n = 108). The ICC showed very high reliability (ICC = 0.988, n = 21). The Huet questionnaire is an easy, rapidly administered tool that correlated highly with [Formula: see text] in this sample population.

Purpose: To investigate stereo acuity of professional athletes in an open (baseball) and closed (golf) skilled sport compared to nonathletes using a new digitized version of the Titmus Stereo Test/Wirt Circles. Additionally, to examine the new test for reliability and validity. Methods: Participants included professional baseball players (PBP; n = 265) and professional women golfers (LPGA; n = 52), and nonathletes (n = 107). All participants were tested on the RightEye Fine Depth Perception (FDP) test and a subset (n = 20) was retested to determine reliability and internal consistency. A different subset (n = 81) was tested for validity comparing the Titmus Stereo Test/Wirt Circles to the RightEye FDP test. Cronbach’s Alpha, intraclass correlation coefficients (ICC) were examined for reliability and ANOVA was conducted to determine convergent validity as well as differences in stereo acuity between groups. Results: Results: The test was revealed to have high reliability and validity, therefore being a good measure of stereo acuity. Furthermore, significant differences (p<.001) between athletes and non-athletes were found. Both PBP and LPGA athletes were significantly different from non-athletes (p<.05). No differences were found between athlete groups. Conclusions: The RightEye FDP test is both reliable and valid and can therefore be used confidently as a measure of static stereo acuity. Elite athletes in open and closed skills show significantly better stereo acuity than non-athletes.

Abstract Background Postpartum maternal functioning has the potential to affect the quality of interaction between mother and child. A proper assessment of maternal functioning requires a comprehensive and accurate tool. The objective of this study was to prepare a Persian version of the Barkin Index of Maternal Functioning (BIMF) and evaluate its psychometric properties in order to determine its applicability in Iranian mothers. Methods The BIMF was translated into Persian and then culturally adapted for Iranian women. After evaluating face and content validity, to perform factor analysis, a cross-sectional study was conducted using the Persian version of BIMF. The data was collected from two unique groups of 250 mothers (in all 500 mothers) who had infants 2 to 12-months old and who were selected using a two-stage cluster sampling method. Factor analysis, Pearson’s correlation, intra-class correlation coefficients (ICC), composite reliability (CR) and Cronbach’s alpha were employed in order to evaluate structural validity and reliability. Results Exploratory factor analysis resulted in a five-factor structure consisting of 20 items. Subsequently, confirmatory factor analysis (X 2/ df = 1.61, RMSEA = 0.050, GFI = 0.91, CFI = 0.91) confirmed that the Persian version had satisfactory goodness of fit. Reliability and internal consistency were confirmed with a CR of 0.77, an ICC of 0.87 and a Cronbach’s alpha of 0.81. Conclusions The findings indicated that the Persian version of the BIMF is a valid and reliable instrument for assessing maternal functioning among Iranian mothers.

Professionals with burnout have negative physical and psychological effects, with adverse consequences in their workplace. Burnout mainly affects assisting professions; amongst them, police work is one of the professions at risk of suffering from this syndrome. The aim of this research is to study the adequacy of the Maslach Burnout Inventory and Granada Burnout Questionnaire instruments to measure burnout in police officers through the study of the reliability and validity (concurrent and predictive) of these instruments. A cross-sectional study was carried out. The sample was composed of 1884 police officers, mostly men (85.4%), with an average age of 35.04 (SD = 8.30). The Maslach Burnout Inventory and Granada Burnout Questionnaire were used to measure burnout. The results obtained in this study support the adequacy of both instruments for measuring burnout. The correlation coefficients between the dimensions are significant, with a medium-high magnitude. Participants with burnout had significantly higher scores in emotional exhaustion and depersonalization and lower scores in personal accomplishment in both instruments. The area under the curve estimated for the Granada Burnout Questionnaire provided evidence of the predictive validity of the instrument. The police profession needs validated and sensitive tools to identify police changes in the dimensions of burnout. The Granada Burnout Questionnaire instrument correctly classifies burnout in police professionals.

Abstract. Background: Only few food frequency questionnaires (FFQs) have been specifically designed and validated for toddlers. There is no valid instrument to assess usual intakes of Iranian toddlers. The present study was designed to develop a FFQ, and to examine its validity and reliability among toddlers. Material and methods: This cross-sectional study was conducted in 2019 in Iran. Mothers of 100 toddlers completed a semi-quantitative FFQ with 99 items as well as three non-consecutive dietary records. Data on maternal age, education, toddler gender, birth order, birth weight, current weight and height, and the age of beginning complementary foods were collected. By comparing the results obtained from dietary records and the FFQ, we assessed the relative validity. Reliability was evaluated by intra-class correlation coefficients between results of two FFQs administered with four weeks intervals to the same participants (n=20), as well as weighted kappa. The Bland-Altman plots were used to assess the level of agreement between two FFQs. Results: Mean and standard deviation (SD) of age was 32.71 (4.76) years and 22.42 (3.52) months, for mothers and toddlers, respectively. The FFQ showed acceptable validity and reliability. The correlation coefficients for the first FFQ were 0.82 (energy), 0.81 (fats), 0.60 (carbohydrate), 0.96 (calcium), 0.39 (iron) and 0.24 (vitamin C), all P-values were <0.001, except for vitamin C (P: 0.02). Reliability coefficients were between 0.77 (vitamin C) and 0.99 (calcium, potassium, phosphorus, zinc, riboflavin, vitamin B12, vitamin E and D). The Cronbach’s Alpha was 0.91, showing high reliability. Conclusion: The present study provided a thorough assessment of both validity and reliability of T-FFQ, and indicated acceptable validity as compared with three-day dietary records and good reliability. Therefore, this FFQ could be a useful tool to evaluate usual dietary intake of toddlers.

AbstractObjectivesThe purpose of this study is to develop a self-administered version of the Health of the Nation Outcome Scales for Older Adults (HoNOS65+) in Spanish – the HoNOS65+A – and to study its reliability and validity.MethodsThere are two phases in the study: construction of the HoNOS65+A and the study of its psychometric properties. In the second phase, 179 users of 10 services for older people of Madrid were interviewed. They completed the HoNOS65+A, the Spanish version of the HoNOS65+, and other instruments that evaluate similar constructs. Reliability (internal consistency with the other-administered HoNOS65+, intraclass) and validity (concurrent, discriminant, and criterion validity) were analyzed.ResultsHigh reliability indexes (intraclass correlation coefficients) were found for all the scales (HoNOS65+ and HoNOS65+A), except for items 4 and 6. Moreover, the HoNOS65+A has satisfactory concurrent (except 4, 6, and 9) and discriminant validity (except for items 4 and 10). Considering all these data and some theoretical points the items 4 and 6 have eliminated from the scale. Upon eliminating items 4 and 6, the analysis of the reliability (Cronbach's Alpha) and criterion validity (discriminant function among autonomous and assisted people) presents positive values.ConclusionThe results indicate that the HoNOS65+A is a useful measure that does not assess a homogeneous area but instead different aspects of health and psychosocial functioning.

PurposeTo evaluate the capability of wide-field spectral-domain optical coherence tomography (SD-OCT) corneal sublayer pachymetry to distinguish between keratoconus and pellucid marginal degeneration (PMD).MethodsThis prospective cross-sectional study included 69 eyes (59 with keratoconus and 10 with PMD) of 69 patients. All patients were examined three subsequent times with the RTVue XR system. Pachymetry maps of the total cornea (CT), the epithelium (ET) and the stroma were generated using the onboard software. For analysis of reliability, the coefficients of variation and intraclass correlation coefficients (ICC) were calculated. Receiver operating characteristic analyses were performed to elaborate the most accurate pachymetric parameters for distinguishing between PMD and keratoconus.ResultsOverall repeatability of (sublayer) pachymetry was comparably good in both keratoconus (ICC ranging between 0.827 and 0.986) and PMD (ICC ranging between 0.753 and 0.998). Measurement reliability in keratoconic eyes was a negative function of Kmax (p<0.05). As compared with keratoconus, PMD exhibited higher CT (526±31 µm vs 503±30 µm; p=0.02) and ET (56±7 µm vs 51±5 µm; p=0.02) in the inferotemporal 2–5 mm sector as well as lower ET in the inferior 7–9 mm sector (52±5 µm vs 57±5 µm; p<0.01). The calculated ratio between CT in the inferotemporal 2–5 mm and in the inferior 7–9 mm sector yielded the highest diagnostic accuracy for distinguishing between PMD and keratoconus with an area under the curve of 0.977 and an optimal cut-off value of 0.90.ConclusionWide-field SD-OCT corneal sublayer pachymetry showed good reliability in PMD and keratoconus and may be useful to differentiate between the two ectatic diseases.
