Final Questionnaire

Objectives: To develop a questionnaire that specifically evaluates the ability of trans-tibial amputees to don and doff a prosthesis and to investigate the psychometric properties of the newly developed questionnaire. Background: Prosthesis should be donned and doffed few times during the day and night; thus, it is important to measure ease of donning and doffing. Study design: A cross-sectional study. Methods: The questionnaire was designed and evaluated by a group of experts. The final questionnaire was administered to 50 individuals with trans-tibial amputation. A test–retest study was also conducted on 20 amputees to assess the repeatability of questionnaire items. Results: The prosthesis donning and doffing questionnaire was developed and tested through a pilot study. Based on Kappa index, the questionnaire items showed correlation coefficients greater than 0.7, which indicate good reliability and repeatability. The majority of the participants had good hand dexterity (80%) and could perform all types of grasps. The mean satisfaction scores with donning and doffing were 69.9 and 81.4, respectively. Most of the respondents needed to don and doff the prosthesis 3.44 times per day. Based on a 7-point score, the total scores ranged between 3 and 7. Conclusion: The prosthesis donning and doffing questionnaire items showed good psychometric properties. A scoring method was suggested based on the pilot sample, which requires further evaluation to be able to differentiate between more suspension types. A larger international multicenter evaluation is required in the future to measure the responsiveness of the scales. This questionnaire will be useful in the evaluation of the ability of amputees to don and doff a trans-tibial limb prosthesis. Clinical relevance Donning and doffing of prostheses are challenging tasks for many lower limb amputees. The prosthesis donning and doffing questionnaire, on its own or combined with other prosthetic evaluation questionnaires, has the potential to help manufacturers, clinicians, and researchers gain knowledge and improve the donning and doffing qualities of prostheses.

Abstract Background and Objectives Ageism toward older adults, prevalent in contemporary societies, seems to be internalized during childhood and consolidated during adolescence. Although several instruments have been developed to measure adolescents’ ageism, they present a number of limitations. The study aimed at developing a new instrument, the Adolescents’ Ageism Toward Older Adults Scale, and testing its psychometric properties. Research Design and Methods A 3-phase process was followed: the instrument’s items were developed empirically from focus groups of adolescents; its content validity was evaluated; and finally, its psychometric properties were tested through a multicenter cross-sectional study involving 575 adolescents. Results Exploratory factor analysis of the new scale retained 33 items grouped into six factors: Moodiness, Traditionalism, Physical deterioration, Anti-technologism, Sageness and Sociability. Confirmatory factor analysis evidenced a second-order factor structure. Omega coefficients measuring internal consistency were above the cut-off of 0.60 for the six factors except for Anti-technologism. Intraclass correlation coefficients for the entire scale and for the six factors were greater than 0.70, again excepting Anti-technologism. Discussion and implications The Adolescents’ Ageism Toward Older Adults Scale is a promising measure of adolescents’ negative and positive attitudes toward older adults. Its validation highlighted some criticalities that can be resolved by a few modifications. Further testing of the scale should be conducted after these modifications.

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.

CONTEXT AND OBJECTIVE: Lifestyle includes the personal attitudes or behavioral patterns that result in risks or benefits to the individual's own health or that of others. Children's health is particularly determined by their mother's lifestyle. The objective here was to develop and evaluate the reliability of a questionnaire capable of describing the lifestyles of preschoolers' mothers in terms of their activities, interests, opinions and values. DESIGN AND SETTING: Cross-sectional study conducted in a public university. METHODS: This study was conducted between January 2010 and March 2011, among 255 mothers of preschoolers living in the southeastern region of the municipality of São Paulo. A proportional stratified random probabilistic sample with two strata was selected: schools were drawn and then the children. Three instruments found in the literature were used to create the lifestyle questionnaire. The questionnaire was developed in eight stages: preliminary pretest, cultural adaptation, second pretest, pilot study, semantic correction and adaptation, third pretest, final research and final retest. Cronbach's alpha and pairwise correlation coefficients were used. RESULTS: The Cronbach's alpha value in the final version was 0.83 and the pre and post-test pairwise correlation coefficients were greater than 0.5. Factor analysis identified five factors that explained 73.51% of the correlation variance. As a result, seven variables were eliminated from the questionnaire. CONCLUSIONS: The questionnaire described five lifestyle domains, with good reliability, and can be used in combination with preschoolers' health and nutritional outcomes.

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.

Background: Resilience is a dynamic system for successful adjustment with various circumstances, particularly adverse living conditions. In this respect, the Child and Youth Resilience Measure (CYRM-12) can simultaneously assess the individual, relational, contextual, and cultural resources of resilience. Objectives: The present study aimed to investigate the psychometric properties of the Persian version of CYRM-12 in Iranian youth. Methods: In this cross-sectional study, a total number of 440 students aged 14 - 18 years were enrolled. The students were studying in middle and high schools (the academic year of 2019 - 2020) in the city of Islamshahr, Iran, and were selected using random cluster sampling. Data collection questionnaires included the CYRM-12, CYRM-28, Warwick-Edinburgh Mental Well-Being Scale (WEMWBS), and Depression, Anxiety, and Stress Scale (DASS-21). Results: Our results supported the one-factor structure and showed that the given measure had a good fit (χ2/DF = 2.63, RMSEA = 0.06, CFI = 0.95, and GFI = 0.95). The internal consistency measured by Cronbach’s alpha coefficient was also satisfactory (0.79). As well, the test-retest reliability determined by Pearson’s correlation coefficient (with a two-week interval) was obtained 0.70. Moreover, this scale had acceptable convergent and divergent validities. Conclusions: The Persian version of the CYRM-12 delivered good reliability and validity to assess resilience in Iranian youth.

Background and PurposeModified Engulfment Scale (MES) measure the impact of a schizophrenic illness on an individual’s self-concept. The objective of this study was to determine psychometric properties of the Turkish form of MES (MES-T).MethodsThis cross-sectional study were included 162 schizophrenia patients with a convenience sampling method.ResultsBased on the results of factor analysis, five items were removed from the original version of the scale. It was determined that the MES-T consists of 25 items, and it has three factors: change in self-concept, belief in treatment, and future expectation. As a result of Pearson product-moment, low and moderate correlation coefficients were obtained between subscales, and moderate and high correlation coefficients were achieved between the subscales and total score of the scale.ConclusionsThe scale was found to be applicable for schizophrenia patients in Turkish population.

Mediterranean diet (MD) is among the most commonly investigated diets and recognized as one of the healthiest dietary patterns. Due to its complexity, geographical and cultural variations, it also represents a challenge for quantification. The aim of this cross-sectional study was to assess reliability and validity of the Croatian version of the 14-item Mediterranean Diet Serving Score (MDSS), using the Mediterranean Diet Adherence Screener (MEDAS) as the referent test. We included the exploratory sample of 360 medical students, and a confirmatory sample of 299 health studies students from the University of Split, Croatia. Test-retest reliability and validity of the MDSS were tested using intra-class correlation coefficients (ICC), while Cohen’s kappa statistic was used to test correct classification of subjects into MD adherent/non-adherent category. A very good reliability was shown for the overall MDSS score (ICC = 0.881 [95% CI 0.843–0.909]), and a moderate reliability for the binary adherence (κ = 0.584). Concurrent validity of the MDSS was also better when expressed as a total score (ICC = 0.544 [0.439–0.629]) as opposed to the adherence (κ = 0.223), with similar result in the confirmatory sample (ICC = 0.510 [0.384–0.610]; κ = 0.216). Disappointingly, only 13.6% of medical students were adherent to the MD according to MDSS, and 19.7% according to the MEDAS questionnaire. Nevertheless, MDSS score was positively correlated with age (ρ = 0.179: P = 0.003), self-assessed health perception (ρ = 0.123; P = 0.047), and mental well-being (ρ = 0.139: P = 0.022). MDSS questionnaire is a short, reliable and reasonably valid instrument, and thus useful for assessing the MD adherence, with better results when used as a numeric score, even in the population with low MD adherence.
