Test-retest Validity Research Articles

Normative Data for the Famous People Fluency Test in the Adult French-Quebec Population and Validation Study in Mild Cognitive Impairment and Alzheimer's Disease.

The production of words in verbal fluency tests relies heavily on executive functions and linguistic abilities. New tests such as the famous people fluency test can also be useful in clinical practice and research. This test, in which participants are asked to name so many famous people, has the potential to distinguish healthy individuals from participants with neurological disorders such as mild cognitive impairment or Alzheimer's disease. The aim of this study was to determine the psychometric validity of the test (Study 1) and to provide normative data in the adult population of French Quebec for the famous people fluency test (Study 2). The results of the normative study, derived from a sample of 378 healthy individuals between the ages of 50 and 92, showed that age and educational level significantly influence performance on the test. Therefore, percentile ranks were calculated for performance on the famous people fluency test, stratified for these two variables. The results of Study 2 showed that the test differentiated the performance of healthy participants from the performance of participants with mild cognitive impairment or Alzheimer's disease. The results also showed that the famous people fluency test has adequate convergent validity, established with a semantic fluency test, and that the results showed good stability over time (test-retest validity). Norms and psychometric data for the famous people fluency test will improve the ability of clinicians and researchers to better recognize executive and language impairments associated with pathological conditions.

Measurement properties and interpretability of the Patient-Reported Impact of Dermatological Diseases (PRIDD) measure.

Patient-reported outcome measures (PROMs) are crucial for assessing the impact of dermatological conditions on patients' lives, but the existing dermatology-specific PROMs are not recommended for use according to the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN). We developed the Patient-Reported Impact of Dermatological Diseases (PRIDD) measure in partnership with patients. It has strong evidence of content validity, structural validity, internal consistency, acceptability, and feasibility. To test PRIDD's remaining measurement properties and establish the interpretability of scores against the COSMIN criteria using classic and modern psychometric methods. A global longitudinal study consisting of two online surveys administered two to four weeks apart. Adults (≥ 18 years) living with a dermatological condition were recruited through the International Alliance of Dermatology Patient Organizations' (GlobalSkin) membership network. Participants completed PRIDD, a demographics questionnaire, and other related measures including the Dermatology Life Quality Index (DLQI). We tested PRIDD's criterion validity, construct validity and responsiveness (Spearman's ρ, independent-samples t-tests and ANOVA), test-retest reliability (interclass correlation coefficient [ICC]), measurement error (Smallest Detectable Change or Limits of Agreement [LoA], distribution-based Minimally Important Change [MIC]), floor and ceiling effects (number of minimum and maximum scores and Person-Item Location Distribution Maps), score bandings (κ coefficient of agreement) and anchor-based MIC. 504 patients with 35 dermatological conditions from 38 countries participated. Criterion validity (ρ = 0.79), construct validity (76% hypotheses met), test-retest validity (ICC = 0.93), and measurement error (LoA = 1.3 < MIC = 4.14) were sufficient. Floor and ceiling effects were in the acceptable range (< 15%). Score bandings were determined (κ = 0.47), however, the anchor-based MIC could not be calculated due to an insufficient anchor. PRIDD is a valid and reliable tool to evaluate the impact of dermatological disease on patients' lives in research and clinical practice. It is the first dermatology-specific PROM to meet the COSMIN criteria. These results support the value of developing and validating PROMs with a patient-centred approach and using classic and modern psychometric methods. Further testing of responsiveness and MIC, cross-cultural translation, linguistic validation, and global data collection are planned.

Development and validation of a tool to assess patient and caregiver satisfaction for minor pediatric surgical procedures

IntroductionPatient satisfaction questionnaires offer valuable perspectives on patient experiences and the quality of healthcare received. Despite their importance, a gold standard for measuring patient satisfaction in pediatric surgery remains elusive. This study introduces a patient satisfaction questionnaire designed to fill the gap in evaluating patient experiences specifically in pediatric surgical settings, aiming to create a standardized measure for assessing patient satisfaction. MethodsThe think-aloud method was used with patient advisors and an expert panel of hospital stakeholders to refine a novel patient and caregiver satisfaction tool. Through an iterative process, data was gathered, analyzed and the survey progressively revised. The final survey was then pilot tested. ResultsThree patient advisors and seven hospital stakeholders participated in the study. The think-aloud method was used to establish cognitive, content, and face validity. There were five distinct satisfaction domains established. Pilot testing included 30 participants and was used to establish construct validity and test-retest reliability. ConclusionsThis study addresses the existing gap in measuring patient satisfaction in pediatric surgery settings. The think-aloud method was used to ensure cognitive, content, and face validity ensuring multiple domains are addressed. Pilot testing of the tool showed feasibility in both the operating room and minor procedure room setting while also demonstrating test re-test validity. These results indicate that this questionnaire holds promise for use in a variety of pediatric surgical settings. Further research is necessary to confirm these findings in larger, more diverse populations and to assess its impact on improving patient care and experiences.

Reliability and validity of the Turkish version of the patellofemoral pain severity scale in patients with patellofemoral pain syndrome

Purpose The aim of this study was to investigate the Turkish validity and reliability of the Patellofemoral Pain Severity Scale (PSS) in patients with patellofemoral pain (PFP) and to adapt it to Turkish. Materials and methods A pilot study was conducted with 10 patients. 123 patients underwent PSS test-retest at 24–48 h intervals. Construct validity, correlations of PSS with other scales Timed Up and Go Test (TUG), Stair Climbing and Descending Test (SCD), Anterior Knee Pain Scale (AKPS), Tegner Activity Scale (TAS), Lysholm Knee Scoring Scale (LDSS), Knee Outcome Survey Activities of Daily Living Scale (KOS-ADL) were evaluated. Results The content validity index value of the scale was 0.95. The overall internal consistency (Cronbach α: 0.88) was high. Item-total correlations of the scale were between 0.51 and 0.7. In the evaluation of the convergent validity of the PSS, it was found that there was a positive correlation between the PSSS and TUG and SCD, and a negative correlation between the PSS, TAS, LDSS and KOS-ADL (p = 0.000). Conclusions In this study, it was determined that the PSSS scale had good internal consistency, test-retest validity and adequate construct validity when compared with the KOS-ADL, LDSS and AKPS.

Canadian French Translation and Validation of the Neck Dissection Impairment Index: A Quality of Life Measure for the Surgical Oncology Population.

Neck dissections (ND) are a routine procedure in head and neck oncology. Given the postoperative functional impact that some patients experience, it is imperative to identify and track quality of life (QoL) symptomatology to tailor each patient's therapeutic needs. To date, there is no validated French-Canadian questionnaire for this patient-population. We therefore sought to translate and validate the Neck Dissection Impairment Index (NDII) in Canadian French. A 3-phased approach was used. Phase 1: The NDII was translated from English to Canadian French using a "forward and backward" translational technique following international guidelines. Phase 2: A cognitive debriefing session was held with 10 Canadian French-speaking otolaryngology patients to evaluate understandability and acceptability. Phase 3: The final version was administered prospectively to 30 patients with prior history of ND and 30 control patients. These patients were asked to complete the questionnaire 2 weeks after their first response. Test-retest reliability was calculated with Spearman's correlation. Internal consistency was elicited using Cronbach's alpha. NDII was successfully translated and validated to Canadian French. Cronbach's alpha revealed high internal consistency (0.92, lower 95% confidence limit 0.89). The correlation for test-retest validity were strong or very strong (0.61-0.91). NDII is an internationally recognized QoL tool for the identification of ND-related impairments. This validated Canadian French version will allow clinicians to adequately assess the surgery-related QoL effect of neck surgery in the French-speaking population, while allowing French institutions to conduct and/or participate in multisite clinical trials requiring the NDII as an outcome measure.

Construct Validity and Test-Retest Reliability of Questionnaires to Assess Workplace Violence Risk Factors (QAWRF): A Tripartite Perspective of Worksite-Specific Determinants in Healthcare Settings.

Among available workplace violence (WPV) interventions, only data-driven, worksite-based, and risk-based approach WPV interventions had moderate evidence for effectiveness in decreasing the risk of WPV. The Questionnaires to Assess Workplace Violence Risk Factors (QAWRF) had been previously developed to determine the level of WPV risk factors in each healthcare setting based on the tripartite perspective of key stakeholders to enable effective WPV interventions. This study aimed to determine the construct validity and test-retest validity of QAWRF. QAWRF, a three-component instrument consisting of QAWRF-Administrators, QAWRF-Workers, and QAWRF-Clients, had previously undergone content validation, face validation, and internal consistency reliability testing. 965 respondents were recruited to examine the construct validity of QAWRF, and a subset of these (n = 90) were retested again at an interval of three weeks to assess its test-retest reliability. Confirmatory factor analysis (CFA) was performed, and fitness indices, average variance extracted, correlation coefficient, composite reliability, and intraclass correlation coefficient were determined. QAWRF-Administrator, QAWRF-Worker, and QAWRF-Client had acceptable factor loadings (≥0.6), absolute fit (Root Mean Square Error of Approximation > 0.1), incremental fit (Confirmatory Fit Index and Tucker Lewis Index > 0.9), parsimonious fit (Chi-square/degree of freedom < 5), correlation coefficient between construct (≤0.85), discriminant validity index, and construct reliability (≥0.6). CFA supported a four-factor model for QAWRF-Administrator and QAWRF-Worker, and a two-factor model for QAWRF-Client. QAWRF holds good construct validity and test-retest reliability. By using QAWRF, healthcare managers can identify specific WPV risk factors that are perceived by stakeholders as prevalent at a particular workplace, and these findings can contribute towards data-driven, worksite-specific, and targeted WPV interventions in healthcare settings that are expected to be resource-efficient and more effective than general WPV interventions.

Reliability and validity of the Chinese version of the COMPI Fertility Problem Stress Scale-Short Form for infertile women.

To translate and culturally adapt the COMPI Fertility Problem Stress Scale-Short form (COMPI-FPSS-SF) and to test its reliability and validity in China. The cross-sectional study adopted Brislin's translation model to translate, synthesize, back-translate, and cross-culturally adapt the COMPI-FPSS-SF for the Chinese setting. A total of 279 infertile women were invited to participate in the study to test the reliability and validity of the scale between March and June 2021. It was verified that the Chinese version of the COMPI-FPSS-SF has three domains with nine items. The Cronbach's α coefficient of the total scale was 0.907, and the coefficient for each dimension ranged from 0.760 to 0.855. The test-retest validity was 0.891. The exploratory factor analysis extracted three common factors with eigenvalues of 4.499, 1.124, and 1.011 and a cumulative variance contribution of 73.706. The validity factor analysis showed good results for the three-factor structure fit. The criterion-related validity with the Fertility Inventory Short-Form Scale was 0.649. The above analysis revealed statistically significant differences (P < 0.001). The Chinese version of the COMPI-FPSS-SF can be used for the assessment of fertility-related stress in infertility patients in China with good reliability and validity.

Athlete Sleep Screening Questionnaire in Japanese: Adaptation and Validation Study.

General screening methods for athletes are limited. This study aims to analyze the reliability and validity of the Japanese version of the athlete sleep screening questionnaire. In total, 111 female collegiate athletes completed the initial test and retest. The independent variables included the kind of sports of the participants and their athletic level, grade (freshman, sophomore, junior, and senior), and age. The reliability of the questionnaire was assessed using Cronbach'salpha and intraclass correlation coefficients. Athletes competing in team sports and individual sports were compared to evaluate for differences. A total of 38.7% of athletes had moderate to severe sleep difficulty score. Their Cronbach's alpha for test and retest were .34 and .44, respectively. The intraclass correlation coefficient indicated sufficient internal consistency and test-retest validity. The mean sleep difficulty scores were 7.0 (2.3) and 6.5 (2.1) for test and retest, but no significant difference was observed between the individual and team sport athletes. Results of multivariable regression analysis revealed that having sleep and performance issues during travel was related to sleep difficulty scores (Coef 1.44, P < .01). Athletes of all levels have sleep disorders. The Japanese version of athlete sleep screening questionnaire has been validated with sufficient test-retest validity but has poor internal consistency. Thus, although Japanese version of the athlete sleep screening questionnaire is an appropriate questionnaire for assessing sleep disorders in athletes whose primary language is Japanese, future research is needed to optimize the questionnaire accounting for cultural variation.

Validity of self-reported sleep duration in the Cancer Prevention Study- 3.

We examined the one-year test re-test reliability and validity criterion of survey-assessed sleep duration collected from two separate questions. The Activity Validation Sub Study included 751 participants of the Cancer Prevention Study-3 study to further investigate rest/activity cycles. Sleep duration was collected using three methods: survey, Daysimeter device, and sleep diary. Survey-assessed sleep duration was collected using 2 different questions, each with different response options (categorical and continuous). Selected participants (n = 170) were asked to wear a Daysimeter device for seven consecutive days for two non-consecutive quarters. Participants were excluded from the current study due to incomplete/implausible survey or device data or reported working night shift. We calculated reliability of pre- and post-survey sleep duration for both survey question using Spearman correlation. We used the method of triads to estimate the validity coefficient (VC) between the three sleep duration measurements in the present study and the "true" latent sleep duration measure, and bootstrapping methods to calculate the 95% confidence intervals (95%CI). Of 119 participants included in the study (52.10% male), test-retest correlation showed strong and moderate correlations for sleep duration collected continuously and categorically, respectively. The VC for survey-assessed continuous sleep duration was 0.82 (95%CI 0.71, 0.90) for weekday and 0.68 (95%CI 0.46, 0.83) for weekend. Performance of the VC was slightly weaker for survey-assessed categorical sleep duration (weekday VC = 0.57 95%CI 0.42, 0.71; weekend VC = 0.47 95%CI 0.29, 0.62). The two survey-assessed sleep duration questions used in the AVSS and CPS-3 cohorts are valid approximations of sleep duration.

АДАПТАЦИЯ И ВАЛИДИЗАЦИЯ ШКАЛЫ ПРОЭКОЛОГИЧЕСКОЙ МОТИВАЦИИ НА РОССИЙСКОЙ ВЫБОРКЕ

The objective of the study was the translation and adaptation of Motivation Toward the Environment Scale (Pelletier et al., 1998) into the Russian language. The methodology is based on the theory of self-determination, where behavior is determined by different reasons and the level of control. The scale contains 6 types of motivation: intrinsic motivation, extrinsic motivation, which includes integrated, identified, introjected and externally regulated motivation, and amotivation. On a sample of 462 respondents, the factorial structure of the scale and the internal consistency of the subscales were confirmed. Further, the test-retest validity of the scale was demonstrated (n = 56). To study convergent validity, correlations of motivation types with environmental concerns and nature connectedness were considered. The most self-determined types of motivation (intrinsic, integrated, identified, and introjected) were positively related to each other and to proenvironmental variables. The identified regulation, which focuses on the expediency of pro-environmental actions, is the most common, both in Canada, where the scale was developed, and in Russia. Other types of motivation were also positively related to each other. Externally regulated motivation, which considers social influence rather than economic incentives in this scale, was the least related to other study variables. Additionally, the influence of sociodemographic characteristics on the types of motivation was considered, where gender and income level turned out to be significant variables. The analysis revealed that the adapted scale is largely equivalent to the original one. Based on the obtained results, the reliability, the test-retest, and the convergent validity of the adapted inventory for measuring pro-environmental motivation were proved.

Investigation of the validity and reliability of the 3-meter backward walk test in high functional level adults with lower limb amputation.

Backward walk training has an important place in the rehabilitation programs of lower extremity amputees. This study aimed to investigate the test-retest validity and reliability of the 3-meter backward walk test (3MBWT), minimal detectable change, and the cutoff time in high functional level adults with lower limb amputations (LLAs). Adults with LLA (n = 30) and healthy adults (n = 29) were included in the study. This is a randomized cross-sectional study. The Modified Fall Efficacy Score, Rivermead Mobility Index, and Timed Up and Go test with the 3MBWT were used to evaluate the concurrent validity of the test. The second evaluation (retest) was performed by the same physiotherapist 1 week following the first evaluation (test). The validity was assessed by correlating the 3MBWT times with the scores of other measures and by comparing the 3MBWT times between adults with LLA and healthy adults. Test-retest reliability of the 3MBWT was excellent. The intraclass correlation coefficient for the 3MBWT was 0.950. The standard error of measurement and minimal detectable change values were 0.38 and 0.53, respectively. A moderate correlation was found between the 3MBWT, Modified Fall Efficacy Score, Timed Up and Go test, and Rivermead Mobility Index ( p < 0.001). Significant differences in the 3MBWT times were found between adults with LLA and healthy controls ( p < 0.001). The cutoff time of 3.11 s discriminates healthy adults from high functional level adults with LLA. The 3MBWT was determined to be valid, reliable, and easy-to-apply tool in high functional level adults with LLA. This assessment is a useful and practical measurement for dynamic balance in high functional level adults with LLA.

Athlete Sleep Behavior Questionnaire in Japanese (ASBQ-J): An Adaptation and Validation Study.

The Athlete Sleep Behavior Questionnaire (ASBQ) is an 18-item self-reported questionnaire that can be used to screen for sleep disorders in athletes and assess environmental, behavioral, and sports-related factors along with sleep disorders. This study aimed to analyze the reliability and validity of the ASBQ translated into Japanese (ASBQ-J). 111 female collegiate athletes completed both the initial test and retest. Independent variables were what kind of sports they perform, level as an athlete, grade (freshman, sophomore, junior, senior), and age. The reliability of the survey was assessed using Cronbach's alpha and intraclass correlation, and Pearson's correlation coefficient was calculated to determine the correlation between the total ASBQ scores and three components which were routine/environmental, behavioral, and sports factors. A total of 37.8% of athletes had ASBQ scores equal or less than 36 indicating good sleep. However, 19.8% of athletes scored more than 42, indicating poor sleep. Cronbach alpha was 0.62 and 0.65 for test and retest, respectively. Intraclass correlation was 0.78 (P < 0.01), indicating sufficient internal consistency and test-retest validity. Mean ASBQ scores were 38.5 ± 5.0 and 37.0 ± 6.5 for test and retest, respectively, and it was not significantly different between the two groups (P = 0.37). The correlation coefficients between the ASBQ-J and component scores were all statistically significant (all P < 0.01). ASBQ-J is a reliable questionnaire for assessing sleep disorders in athletes whose primary language is Japanese.

Psychometric properties of the Romanian version of the female sexual function index (FSFI-RO)

BackgroundFemale sexual dysfunction (FSD) is a highly prevalent health disorder and no self-report questionnaire on female sexual function is available in Romanian. Therefore we considered the Female Sexual Function Index (FSFI) to be the most appropriate due to its excellent psychometric properties. The FSFI is a measuring scale with 19 items that assess the six domains of female sexual function: desire, arousal, lubrication, orgasm, satisfaction and pain. The paper aims to analyze the psychometric reliability and validity of the FSFI-RO (Romanian Version of the Female Sexual Function Index).Methods385 women (aged 18 to 51) enrolled in the present study. To assess the presence of FSD we used the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) criteria for sexual dysfunction. Then we categorized the participants into two groups: the FSD group (41%) and the healthy control group (59%). Women were then asked to fill out a form that included sociodemographic information and the FSFI-RO questionnaire. A sample of 50 women agreed to re-answer FSFI-RO in a 4-week interval in order to evaluate the test-retest validity of the questionnaire. The data were summarized using descriptive statistics: the test-retest reliability was measured by the intraclass correlation coefficient (ICC); Cronbach’s alpha was employed to evaluate the internal consistency of the Romanian version of the FSFI, and validity was assessed by the content and construct validity.ResultsThe results showed high test-retest reliability, with ICC from 0.942 to 0.991 in the domains and 0.987 in the total score. Regarding the internal consistency of the FSFI-RO, Cronbach’s α coefficients were found to be high (α = 0.944). Convergent construct validity proved to be moderate to high in desire, arousal, lubrication, orgasm and, satisfaction domains, and weak correlation in the pain domain. Regarding the discriminant construct validity, the scores for each domain and the total score showed statistically significant differences between the FSD group and the control group.ConclusionsThe FSFI-RO showed similar psychometric properties to those of the original version, therefore being a reliable and valid instrument that can be used in Romanian-speaking women.

Society's Attitudes Towards Human Augmentation and Performance Enhancement Technologies (SHAPE) Scale

Human augmentation technologies (ATs) are a subset of ubiquitous on-body devices designed to improve cognitive, sensory, and motor capacities. Although there is a large corpus of knowledge concerning ATs, less is known about societal attitudes towards them and how they shift over time. To that end, we developed The Society's Attitudes Towards Human Augmentation and Performance Enhancement Technologies (SHAPE) Scale, which measures how users of ATs are perceived. To develop the scale, we first created a list of possible scale items based on past work on how people respond to new technologies. The items were then reviewed by experts. Next, we performed exploratory factor analysis to reduce the scale to its final length of thirteen items. Subsequently, we confirmed test-retest validity of our instrument, as well as its construct validity. The SHAPE scale enables researchers and practitioners to understand elements contributing to attitudes toward augmentation technology users. The SHAPE scale assists designers of ATs in designing artifacts that will be more universally accepted.

Kannada Translation and Validation of the ESAS-r Renal for Symptom Burden Survey in Patients with End-Stage Kidney Disease.

End-stage kidney disease (ESKD) is a life-limiting illness that leads to significant health-related suffering for the patients and their caregivers. Moreover, disease-directed options such as dialysis and renal transplant might not be universally accessible. Inadequate assessment and management of symptoms often lead to diminished quality of life. For evaluating symptoms and their associated distress, various tools have been identified. However, these are not available for the native Kannada-speaking population for assessing ESKD symptom burden. In this study, we determined the reliability and validity of the Edmonton Symptom Assessment System Revised Renal (ESAS-r: Renal) in Kannada-speaking ESKD patients. ESAS-r: Renal English version was translated into Kannada using the forward and backward method. The translated version was endorsed by Nephrology, Palliative care, Dialysis technology and Nursing experts. As a pilot study, 12 ESKD patients evaluated the content of the questionnaires for appropriateness and relevance. The ESAS-r: Renal Kannada version was validated by administering this tool to 45 patients twice a fortnight. The translated ESAS-r: Renal Kannada version questionnaire had an acceptable face and content validity. Experts' opinion was assessed by content validity ratio (CVR), and the value of CVR of ESAS-r: Renal Kannada version was-'1'-. Internal consistency of the tool was assessed among Kannada-speaking ESKD patients; its Cronbach's α was 0.785, and test-retest validity was 0.896. The validated Kannada version of ESAS-r: Renal was reliable and valid for assessing symptom burden in ESKD patients.

Fear and Stigma of COVID-19 Reinfection Scale (FSoCOVID-19RS): New Scale Development and Validation.

The advent of COVID-19 and its impacts have prompted fear and stigma among people all across the world. Because of stigma, there was often a delay in diagnosis and treatment, which resulted in a poor prognosis. As a result, a reliable scale is required to measure the level of fear and stigma of COVID-19 reinfection. To develop and validate a scale for determining the level of fear and stigma of COVID-19 reinfection. A cross-sectional study including 200 nursing-college students who had previously tested positive for COVID-19 was conducted. The scale's reliability was evaluated by external and internal consistency methods. Construct, convergent, and discriminant validity were evaluated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The scale's mean score was 24.85 ± 11.35, and no floor or ceiling effects were detected. The scale items' reliability, measured by Cronbach's alpha coefficient if an item was deleted, ranged from 0.76 to 0.95, with a total score value of 0.86. The range of convergent validity coefficients was between 0.37 and 0.64. Pearson's correlation coefficients for test-retest validity ranged from 0.71 to 0.93, with a total score of 0.82. The coefficient of split-half correlation was 0.87, while the coefficient of reliability was 0.93. According to the factor analysis, two components had latent roots larger than 1. The rotated component matrix of the two factors revealed that all items had R values over 0.30, indicating that none of them should be excluded. In addition, CFA results revealed that χ2 = 3524, df = 1283, χ2/df ratio = 2.74, p < 0.001, GFI = 0.86, CFI = 0.92, AGFI = 0.88, and RMSEA = 0.05. The scale's convergent and discriminant validity was confirmed. The 14-item, two-dimensional Fear and Stigma of COVID-19 Reinfection Scale (FSoCOVID-19 RS) was demonstrated to have reliable psychometric properties.

Test-Retest Reliability and External Validity of Canadian Diabetes Risk Questionnaire - Turkish

Objectives: The aim of the study was to examine the test-retest reliability and external validity of the Canadian Diabetes Risk Questionnaire (CanRisk). Materials and Methods: Individuals over 40 years of age without any disease were included in the study. Participants were administered the CanRisk, Nottingham Health Profile (NHP), and Visual Analog Scale (VAS). CanRisk test-retest validity was calculated with the interclass correlation coefficient (ICC), and external validity was calculated with the Pearson correlation coefficient. Results: The study included 1349 participants, 549 men and 755 women (mean age 50.03 ± 8.05 years). CanRisk test-retest validity was found to be excellent (0.99). Its external validity was evaluated by examining its correlation with NHP, and it was found that there was a statistically significant, positive weak correlation (p&amp;lt;0.05, r= 0.23). Conclusion: CanRisk -TR was found to be a reliable and valid questionnaire to predict diabetes risk.

Development and validation of the atopic dermatitis and infant skincare knowledge, attitude, and practice (ADISKAP 1.0) scale.

Preserving skin health is crucial for atopic dermatitis control as well as for the thriving of children. However, a well-developed and validated tool that measures the knowledge, attitude, and practice of skin care is lacking. To develop and validate the atopic dermatitis and infant skincare knowledge, attitude, and practice (ADISKAP 1.0) scale that measures parental health literacy on atopic dermatitis and skin care. We conducted a review of the literature, a focus group (two dermatologists and 12 parents), and a panel discussion in order to generate the ADISKAP prototype. Two samples of parents with knowingly superior (dermatologists, n = 59) and inferior (general population, n = 395) knowledge traits participated in the validation of ADISKAP. Cronbach's alpha was reported as a measure of internal consistency, and the intraclass correlation coefficient (ICC) was calculated to assess the test-retest validity. The known-groups technique was used to evaluate construct validity. The ADISKAP scale contained 17 items after content and face validity validation. After removing items that displayed poor test-retest reliability (n = 4) and construct validity (n = 3), 12 items were retained in the ADISKAP 1.0. ADISKAP 1.0 is a reliable and valid tool for assessing parental knowledge, attitude, and practice on infantile atopic dermatitis and skin care.

Adaptation and validation of the Italian Singing Voice Handicap Index-10 (SVHI-10-IT).

The aim of this study was to adapt and validate the Italian version of the singing Voice Handicap Index-10 (SVHI-10-IT). 99 Italian singers were enrolled in the study. All subjects underwent videolaryngostroboscopic examination and were asked to fill out the self-reported 10-item SVHI-10-IT. Laryngostroboscopic examination was pathological in 56 subjects (study group) (56.6%), while it was normal in the remaining 43 singers (control group) (43.4%). Dimensionality, test retest and internal validity for SVHI-10-IT were performed. Videolaryngostroboscopy was used as gold-standard for external validity. The items of SVHI-10-IT were uni-dimensional and Cronbach's α was 0.853 (95% CI = 0.805-0.892). High and comparable area under curve (AUC:0.93 95% CI = 0.88-0.98) values indicate a good ability of the scale to distinguish between the study and control groups. Based on balanced sensitivity (Se = 83.9%) and specificity (Sp = 86.0%), the optimal cut-off score for a singer's perceived voice handicap was 12. The SVHI-10-IT is a reliable and valid instrument to evaluate the self-reported singing voice handicap among singers. It can also be used as a quick screening tool since a score higher than 12 is indicative of a problematic voice as perceived by singers.

Test Retest Reliability and Validity of 1-Minute Sit-to-Stand Test in Patients With Chronic Heart Failure.

The psychometric properties of the 1-minute sit-to-stand (1STS) test have not been investigated in patients with chronic heart failure (CHF). The aim of this study was to evaluate test-retest reliability, construct validity, and minimal detectable change of the 1STS test and to investigate the physiological response to the 1STS test in patients with CHF. Forty-three (43) patients with CHF were included. Demographic and clinical features were recorded. To investigate test-retest reliability, participants performed two 1STS tests on the same day. The correlations between the 1STS test and the 6-minute walk test (6MWT), functional class, pulmonary function, quadriceps muscle strength, and physical activity were investigated for validity. The physiological responses and symptom perception were assessed before and after both the 1STS test and 6MWT. Excellent test-retest reliability was found for the 1STS test, with an intraclass correlation of 0.932 (95% confidence interval 0.874-0.963). The minimal detectable change of the 1STST test was 3.7 repetitions. The 1STS test was correlated with 6MWT distance, age, functional class, pulmonary function, quadriceps muscle strength, and physical activity (p<0.05). The 1STS test showed similar changes to the 6MWT in physiological responses and symptom perception (p>0.05), except for leg fatigue (p=0.02). The 1STS test is reliable and valid in evaluating functional exercise capacity in patients with CHF. The 1STS test reveals similar cardiac demand to the 6MWT. The 1STS test may be considered an option when traditional tests are impractical in terms of space and time.
