The Impact

ABSTRACT Introduction: The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) is a multi-item psychometric instrument used to assess patients' perspective of the impact specifically related to Orthodontics. The cross-culturally adapted Brazilian version of the PIDAQ has demonstrated good reliability, validity and acceptability. Objective: The aim of the present study was to test the validity and reliability of the Brazilian version of the PIDAQ for use among adolescents aged between 11 and 14 years old. Methods: Having established the possibility of maintaining the operational characteristics of the Brazilian version of PIDAQ for the target age group, 194 individuals in the city of Belo Horizonte, Brazil, completed the questionnaire. The subjects were examined for the presence/absence of malocclusion based on the criteria of the Dental Aesthetic Index (DAI) to test discriminant validity. Internal consistency was measured by means of Cronbach's alpha coefficient which ranged from 0.59 to 0.86 for the subscales. Test-retest reliability was assessed by means of intraclass correlation coefficient which ranged from 0.54 to 0.89 for aesthetic concern and psychological impact. Results: Discriminant validity revealed that subjects without malocclusion had different PIDAQ scores in comparison to those with malocclusion. Conclusion: These findings suggest that the Brazilian version of PIDAQ for adolescents has satisfactory psychometric properties and is applicable to this age group in Brazil.

AbstractObjectiveTo test the validity and reliability of the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ)-Albanian version in Kosovar adolescents and assess gender-based differences of malocclusion on PIDAQ subscales.MethodsA sample of 200 adolescents aged 12–15 years were evaluated for orthodontic treatment need by a previous calibrated dental examiner, using the aesthetic component (AC) of the Index of Orthodontic Treatment Need-Aesthetic Concern (IOTN-AC) and the dental aesthetic index (DAI). Internal consistency, test-retest reliability, discriminant validity and gender-based impact of malocclusion on psychosocial impact was assessed.ResultsThe Albanian version of the PIDAQ shows satisfactory internal consistency (α ranging from 0.73 to 0.90) with high test-retest reliability (r > 0.83). The discriminant validity revealed that subjects with minor and severe malocclusion according to dichotomous DAI categorization had different PIDAQ scores. No significant gender-based differences were noted on the impact of malocclusion on psychological and social aspect or Dental Self-confidence (DSC); however, significant gender-based difference was noted on the impact of malocclusion on AC.ConclusionThe Albanian version of the PIDAQ demonstrated good psychometric properties and applicability to this age group in Kosova.

(1) Objectives: This paper aimed to cross-culturally adapt the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) into an Arabic language version (PIDAQ(A)) for measuring the oral health related quality of life related to dental aesthetics among 12–17-year-old Yemeni adolescents. (2) Material and methods: The study comprised three parts, which were linguistic validation and qualitative interview, comprehensibility assessment, and psychometric validations. Psychometric properties were examined for validity (exploratory factor analysis (EFA), partial confirmatory factor analysis (PCFA), construct, criterion, and discriminant validity) and reliability (internal consistency and reproducibility). (3) Results: The PIDAQ(A) contained a new item. EFA extracted three factors (item factor loading 0.375 to 0.918) comprising dental self-confidence, aesthetic concern, and psychosocial impact subscales. PCFA showed good fit statistics (comparative fit index (CFI) = 0.928, root-mean-square error of approximation (RMSEA) = 0.071). In addition, invariance across age groups was tested. Cronbach’s α values ranged from 0.90 to 0.93 (intraclass correlations = 0.89–0.96). A criterion validity test showed that the PIDAQ(A) had a significant association with oral impacts on daily performance scores. A construct validity test showed significant associations between PIDAQ(A) subscales and self-perceived dental appearance and self-perceived need for orthodontic braces (p < 0.05). Discriminant validity presented significant differences in the mean PIDAQ(A) scores between subjects having severe malocclusion and those with slight malocclusion. No floor or ceiling effects were detected.

AbstractObjectiveTo develop and test a scale for healthy eating practices measurement according to the Dietary Guidelines for the Brazilian Population recommendations.DesignMethodological study. The current Brazilian food-based dietary guideline highlights the importance of choosing foods, combining foods to create meals and modes of eating. These recommendations formed the main domains of the scale and served as a basis for the development of ninety-six items, each with a 4-point Likert response option. Content and face validity were tested. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to determine construct validity. Internal consistency was determined using α and ω coefficients, and reproducibility was tested using test–retest.SettingBrazil.ParticipantsA ten-member expert panel was used to assess content validity. Adults aged 18–60 years were included in the face validity (n 20), EFA (n 352), CFA and reliability tests (n 900).ResultsOf the ninety-six initial items, twenty-four were excluded and fifty-five were reworded following the content and face validations. EFA detected a four-domain structure (Food choices, Modes of eating, Planning and Domestic organization), which explained 41 % of the variance. CFA led to a final twenty-four-item model with acceptable goodness-of-fit indices and good reliability measures (α=0·77; ω=0·83). Intraclass correlation coefficient for the total score (0·82) and analysis of the Bland–Altman plot suggested good reproducibility of the scale.ConclusionsThe scale presents good evidence of validity and reliability. This innovative study created a useful tool for evaluation of the impact of the Dietary Guidelines for the Brazilian Population.

OBJECTIVES: to produce evidence of the validity and reliability of the Body Shape Questionnaire (BSQ) - a tool for measuring an individual's attitude towards his or her body image. METHODS: the study covered 386 young people of both sexes aged between 10 and 18 from a private school and used self-applied questionnaires and anthropometric evaluation. It evaluated the internal consistency, the discriminant validity for differences from the means, according to nutritional status (underweight, eutrophic, overweight and obese), the concurrent validity by way of Spearman's correlation coefficient between the scale and the Body Mass Index (BMI), the waist-hip circumference ratio (WHR) and the waist circumference (WC). Reliability was tested using Wilcoxon's Test, the intraclass correlation coefficient and the Bland-Altman figures. RESULTS: the BSQ displayed good internal consistency (±=0.96) and was capable of discriminating among the total population, boys and girls, according to nutritional status (p<0.001). It correlated with the BMI (r=0.41; p<0.001), WHR (r=-0.10; p=0.043) and WC (r=0.24; p<0.001) and its reliability was confirmed by intraclass correlation (r=0.91; p<0.001) for the total population. The questionnaire was easy to understand and could be completed quickly. CONCLUSIONS: the BSQ presented good results, thereby providing evidence of its validity and reliability. It is therefore recommended for evaluation of body image attitudes among adolescents.

Abstract Purpose To determine the validity of wrist range of motion (ROM) measurements by the wearable-controlled ReValidate! wrist-rehabilitation game, which simultaneously acts as a digital goniometer. Furthermore, to establish the reliability of the game by contrasting ROM measurements to those found by medical experts using a universal goniometer. Methods As the universal goniometer is considered the reference standard, inter-rater reliability between surgeons was first determined. Internal validity of the game ROM measurements was determined in a test–retest setting with healthy volunteers. The reliability of the game was tested in 34 patients with a restricted range of motion, in whom the ROM was measured by experts as well as digitally. Intraclass-correlation coefficients (ICCs) were determined and outcomes were analyzed using Bland–Altman plots. Results Inter-rater reliability between experts using a universal goniometer was poor, with ICCs of 0.002, 0.160 and 0.520. Internal validity testing of the game found ICCs of − 0.693, 0.376 and 0.863, thus ranging from poor to good. Reliability testing of the game compared to medical expert measurements, found that mean differences were small for the flexion–extension arc and the radial deviation-ulnar deviation arc. Conclusion The ReValidate! game is a reliable home-monitoring device digitally measuring ROM in the wrist. Interestingly, the test–retest reliability of the serious game was found to be considerably higher than the inter-rater reliability of the reference standard, being healthcare professionals using a universal goniometer.

Background The use of a valid and reliable outcome scoring system is crucial for evaluating the result of different treatment interventions. The aims of this study were to translate and culturally adapt the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scoring system into the Persian language and assess its validity and reliability. Method In total, 57 patients with midfoot injuries were enrolled. Forward-backward translation and cultural adaptation methods were used to develop the Persian version of AOFAS midfoot scoring system. Reliability and internal consistency were assessed using intraclass correlation coefficient (ICC) and Cronbach’s alpha. The discriminant and convergent validities of the scoring system were assessed using the total score of the mental and physical component of SF-36. Results The mean age of the participants was 46.2 ± 16.3 years. The intra-observer reliability of the totals core of the Persian version of AOFAS midfoot scoring system was 0.96 (confidence interval [CI]: 0.92-0.97) and the inter-observer reliability of the scoring system was 0.90 (CI: 0.86-0.95). The Persian version of AOFAS midfoot scoring system had acceptable convergence with physical component scoring system of SF-36 and its subscales (0.57); moreover, it had acceptable discriminant validity with the mental component of SF-36 and its subscales (0.36). Conclusion The Persian version of AOFAS midfoot is a reliable and valid instrument and could be used by Persian language clinicians and researchers. Level of Clinical Evidence: 3

BackgroundPatient feedback surveys are increasingly seen as a key component of health care quality monitoring and improvement.ObjectiveThe study objective was to describe the development and initial psychometric evaluation of a fixed-length questionnaire about the experiences of patients receiving physical therapist treatment in postacute outpatient settings.DesignThis was an instrument development study with validity and reliability testing.MethodsA total of 465 participants attending 3 rehabilitation centers for musculoskeletal conditions completed the questionnaire. A cognitive pretest was applied to the draft version (n=94), and a revised version was evaluated for test-retest reliability (n=90). Analyses to evaluate variance and nonresponse rates for items, the factor structure of the questionnaire, and the metric properties of multi-item scales were conducted.ResultsExploratory factor analyses yielded evidence for a 7-factor structure of the questionnaire, with 3 factors that may be conceptually viewed as professionals' attitudes and behavior (providing information and education, sensitivity to patients' changes, and emotional support) and 4 factors that conceptually reflect organizational environment (duration of attendance, interruptions during care delivery, waiting times, and patient safety). Item-scale correlations ranged from .70 to .93. The percentage of scaling success was 100% for all of the scales. Cronbach alpha coefficients ranged from .70 to .87. Intraclass correlation coefficients ranged from .57 to .80 (median=.68).LimitationsGeneralization to other patients is not known.ConclusionsThe questionnaire has test-retest reliability, and the scales have internal consistency and convergent and discriminant validity. All of the scales are distinct and unidimensional.

BACKGROUND There is strong evidence suggesting that higher levels of cardiorespiratory fitness (CRF) are associated with a healthier metabolic profile, and that CRF can serve as a powerful predictor of morbidity and mortality. In this context, a smartphone app based on the 2-km walk test (UKK test) would provide the possibility to assess CRF remotely in individuals geographically distributed around a country or continent, and even between continents, with minimal equipment and low costs. OBJECTIVE The overall aim of this study was to evaluate the validity and reliability of 2kmFIT-App developed for Android and iOS mobile operating systems to estimate maximum oxygen consumption (VO2max) as an indicator of CRF. The specific aims of the study were to determine the validity of 2kmFIT-App to track distance and calculate heart rate (HR). METHODS Twenty participants were included for field-testing validation and reliability analysis. The participants completed the UKK test twice using 2kmFIT-App. Distance and HR were measured with the app as well as with accurate methods, and VO2max was estimated using the UKK test equation. RESULTS The validity results showed the following mean differences (app minus criterion): distance (–70.40, SD 51.47 meters), time (–0.59, SD 0.45 minutes), HR (–16.75, SD 9.96 beats/minute), and VO2max (3.59, SD 2.01 ml/kg/min). There was moderate validity found for HR (intraclass correlation coefficient [ICC] 0.731, 95% CI –0.211 to 0.942) and good validity found for VO2max (ICC 0.878, 95% CI –0.125 to 0.972). The reliability results showed the following mean differences (retest minus test): app distance (25.99, SD 43.21 meters), app time (–0.15, SD 0.94 seconds), pace (–0.18, SD 0.33 min/km), app HR (–4.5, 13.44 beats/minute), and app VO2max (0.92, SD 3.04 ml/kg/min). There was good reliability for app HR (ICC 0.897, 95% CI 0.742-0.959) and excellent validity for app VO2max (ICC 0.932, 95% CI 0.830-0.973). All of these findings were observed when using the app with an Android operating system, whereas validity was poor when the app was used with iOS. CONCLUSIONS This study shows that 2kmFIT-App is a new, scientifically valid and reliable tool able to objectively and remotely estimate CRF, HR, and distance with an Android but not iOS mobile operating system. However, certain limitations such as the time required by 2kmFIT-App to calculate HR or the temperature environment should be considered when using the app.
