Cross-cultural adaptation, validity and reliability of Turkish version of the Waterloo Handedness and Footedness Questionnaire-Revised

ABSTRACT This study investigated the validity and reliability of Turkish versions of the Waterloo Handedness and Footedness Questionnaire-Revised (WHQ-R and WFQ-R). Turkish versions of the WHQ-R and the WFQ-R, and other assessments (the Handedness Questionnaire and the Footedness Preference Test) were applied to 444 healthy participants aged between 18 and 65 years. The translation and cultural adaptation process of the WHQ-R and the WFQ-R was provided by the following proposed guideline. For test-retest reliability, translated versions were re-applied to 88 participants in a 7-day interval. Cronbach’s alpha of the WHQ-R was 0.984 and that of the WFQ was 0.905. The test-retest intra-class correlation coefficients (ICC) of the WHQ-R varied from 0.741 to 0.933 and those of the WFQ-R from 0.649 to 0.814. There were moderate to strong correlations between the WHQ-R and the Handedness Questionnaire (r = −853, p < 0.001) and between the WFQ-R and the Footedness Preference Test (r = −0.687, p < 0.001). Confirmatory factor analysis revealed a two-factor structure of the WHQ-R and the WFQ-R. The results of this study demonstrated that Turkish versions of the WHQ-R and the WFQ-R are reliable and valid inventories for assessing handedness and footedness in this population.

Scale Development Study: Readiness for Discharge from the Neonatal Intensive Care Unit and Home Care of Premature Infants by Parents.

To develop the readiness for hospital discharge scale for mothers and fathers with a premature infant hospitalised in the neonatal intensive care unit and to test the validity and reliability of this scale. A cross-sectional study. Sakarya University Education and Research Hospital, Sakarya, Turkey, from February to June 2020. This study was conducted with 136 mothers and 133 fathers, who met the inclusion criteria and agreed to participate in the study. After the content validity of the scale was evaluated, the exploratory and confirmatory factor analysis, reliability analysis (Cronbach Alfa) and test-retest reliability were performed. As a result of the factor analysis, items of the mother form and the father form were reduced to 22 and 20, respectively from the scale with 25 items. The confirmatory factor analysis fit indexes were calculated as χ²/df: 1.666, SRMR: 0.0598 in mothers and χ²/df: 2.110, SRMR: 0.0692 in fathers. The Cronbach's Alpha values were 0.911 for mothers and 0.948 for fathers. The test-retest intraclass correlation coefficient was observed as 0.835 for mothers and 0.942 for fathers. In line with the validity and reliability analyses, it was determined that the mother and father forms of the readiness of the parents of premature infants hospitalised in the NICU for the discharge of infants and home care scale were valid and reliable scales for measuring parents' readiness for discharge. Key Words: Parent, Premature, Neonatal intensive care units, Scale, Development, Reliability and validity.

Validity and reliability of the Sports Nutrition Knowledge Questionnaire for the Turkish athletes

Objective: The aim of this research is to determine validity and reliability of Sports Nutrition Knowledge Questionnaire (SNKQ) for the Turkish athletes. Patients and Methods: A total of 210 participants (n = 125 elite athletes and n = 85 Nutrition and Dietetics Department senior students) aged 19-30 years were enrolled in the research. SNKQ was evaluated utilizing the psychometric criteria to determine the reliability of items, test-retest reliability and known groups validity, by significance test (Independent Samples t-Test) of the difference between the two groups. After two weeks, SNKQ was applied again to some participants (n = 42) with the purpose of assuring testretest reliability. Results: The Sports Nutrition Knowledge Questionnaire was detected as valid and reliable according to the high internal consistency value (Kuder Richardson-20 (KR-20) = 0.927) and high test-retest reliability intraclass correlation coefficient (ICC = 0.974). The difference between SNKQ total scores of athletes (36.0 ± 8.1) and Nutrition and Dietetics Department students (59.1 ± 5.98) was statistically significant; thus, the known groups validity was obtained (p &amp;lt; 0.001). Conclusion: The Sports Nutrition Knowledge Questionnaire is valid and reliable. It can be easily used to determine the nutrition knowledge level of the Turkish athletes.

Development and validation of the Japanese version of the team job crafting scale for nurses.

Team job crafting, which refers to designing the task, relational, and cognitive aspects of a job, is thought to be beneficial for nurses working in the ward. There are no scales to assess team job crafting among nurses. This study aimed to develop and examine the reliability and validity of a scale to measure team job crafting. Based on literature reviews and interviews, potential items were created. A total of 293 nurses working on 19 wards in two hospitals in Japan were asked to complete a questionnaire twice. A series of exploratory factor analyses (EFAs) were conducted to select the final items. For convergent validity, multilevel correlations were calculated. Cronbach's α and intra-class correlation coefficients (ICCs) were calculated for reliability. A total of 190 participants responded to the baseline survey and 152 responded to the retest. The EFAs yielded a three-factor structure comprising 13 items. The three factors are task crafting considering the team's growth, cognitive crafting for members' respect and reflection of meaningfulness of work, and relational crafting for smooth information sharing. Cronbach's α ranged from.810 to.831, and test-retest ICCs ranged from 0.571 to 0.710. At the individual level, team job crafting had small-to-moderate correlations with individual levels of job crafting, job control, supervisor support, co-worker support, job satisfaction, workplace social capital, and work engagement. The ICC of the team job crafting scores of 0.125 indicated meaningful variation across wards. At the ward-level, nonsignificant but strong correlations were found with workplace social capital, job satisfaction, and psychological distress. This scale showed acceptable levels of reliability and validity. It would be useful in monitoring and improving team job crafting to increase team members' well-being and performance.

Cross-cultural adaptation into French and validation of the SCAR-Q questionnaire.

Most questionnaires designed to evaluate patient-reported outcomes regarding scarring are available in English. The objective was to generate a validated French version of the SCAR-Q questionnaire. The SCAR-Q questionnaire (including Appearance, Symptom and Psychological impact scales) was translated into French using a translation-back-translation process in accordance with international guidelines (ISPOR and WHO). For validation, two hundred patients consulting in our tertiary center completed the questionnaire. We tested scale reliability (Cronbach's α), floor/ceiling effects and item redundancy (inter-item correlations). Structural validity was tested using confirmatory factor analysis (CFA) with the robust weighted least squares (WLSMV) estimator and Delta parameterization. Model fit was examined using the root mean square error of approximation (RMSEA), the comparative fit index (CFI) and the Tucker-Lewis index (TLI). Correlations between scales and scale repeatability were tested (Spearman coefficient, Intra-class-coefficient). Four steps were required to obtain a translation consistent with the original version. Two hundred patients completed the questionnaire for validation. Internal consistency analysis found Cronbach's alphas > 0.7 for all scales (0.90 <α< 0.97). No floor or ceiling effect was found for all items (max = 85%). A ceiling effect was observed for all scales. Appearance and psychosocial impact scale items showed redundancy, with many inter-item correlations above 0.7. The CFA of the original structure displayed a reasonable fit, with RMSEA = 0.065, CFI = 0.974 and TLI = 0.972. Scales were positively correlated (0.45 < ρ < 0.65; p < 0.001). Test-retest intra-class correlation coefficients ranged from 0.94 to 0.99 for all scales. A French version of the SCAR-Q questionnaire is validated, ready for use.

Test-retest reproducibility of dopamine transporter density measured with [18F]FP-CIT PET in patients with essential tremor and Parkinson's disease.

18F-labeled fluoropropyl-carbomethoxylodopropyl-nor-ß-tropane ([18F]FP-CIT) positron emission tomography (PET) is a useful tool for evaluating disease progression in Parkinson's disease (PD) patients. We evaluated the test-retest reproducibility of [18F]FP-CIT PET measures in essential tremor (ET) and PD patients. Fifteen ET (68.9 ± 6.6years) and 10 PD patients (70.5 ± 6.3years; Hoehn and Yahr stage, 2.3 ± 0.8) underwent two [18F]FP-CIT PET/CT scans with an interval of 48 ± 7day. For both the test and retest studies, standardized uptake value ratios were estimated for 90-min and 3-h acquisitions for the caudate, anterior putamen, and posterior putamen using T1-MRI-based normalization (automatic) and fixed-VOI (manual) methods, with the occipital lobe as a reference. Reproducibility was evaluated by the bias, variability, percent test-retest, within-subject coefficient of variation, repeatability coefficient, and intraclass correlation coefficient (ICC). Reproducibility was excellent, with low variability (ET: 6.99-8.02%, PD: 3.51-6.94%) and high reliability (ICC; ET: 0.88-0.96, PD: 0.98-0.99). The ET group showed higher variability and lower ICCs than the PD group. The variability in the 90-min images (ET: 7.85-8.59%, PD: 1.52-2.75%) was comparable to that in the 3-h images (ET: 6.99-8.02%, PD: 3.51-6.94%). There were no differences in variability among the subregions in the ET group. In the PD group, the variability was high in the posterior putamen (automatic method: 6.94%, manual method: 11.80%). The test-retest variability and ICCs were similar for the manual and automatic methods. [18F]FP-CIT PET is reproducible for the quantitative measurement of DAT binding in both ET and PD individuals, independent of the acquisition time or analysis method. Also, the automaticmethod is more suitable for evaluating early loss of DAT binding inpatients with PD.

Semi-automatic measurements of foot morphological parameters from 3D plantar foot scans

BackgroundFoot healthcare research is focusing increasingly on personalized orthotic and prosthetic devices to address patient-specific morphology and ailments. Customization requires advanced 3D image processing tools to assess foot and leg geometrical parameters and alterations. The aim of this study is to present a new software for the measurement of the foot shape from 3D scans of the foot plantar surface.MethodsA Kinect-based scanning device was used to acquire the 3D foot shape of 44 healthy subjects. A software was developed in Matlab to measure the foot main morphological parameters from foot scans. Principal Component Analysis was used to orientate the foot scans with respect to the same reference system. Accuracy, via percentage errors and Bland-Altman plots, and correlation of the software-based foot parameters were assessed against manual measurements. A normalized Arch Volume Index (nAVI) was proposed and correlated to the traditional Arch Index. Test-retest Intraclass Correlation Coefficient was used to assess the inter-session repeatability of foot measurements.ResultsThe average percentage error between software and manual measurements was 1.2 ± 0.8% for foot length, 9.1 ± 3.7% for foot width, 22.3 ± 13.5% for arch height and 23.1 ± 12.7% for arch depth. Very strong correlations were observed for foot length (R = 0.97) and foot width (R = 0.83), and strong correlations for arch height (R = 0.62) and arch depth (R = 0.74). nAVI was negatively correlated to the Arch Index (R = -0.54). A small difference was found between software and manual measurements of foot length (Δ = 0.92 mm), a software overestimation of foot width (Δ = 8.6 mm) and underestimation of arch height (Δ = -1.4%) and arch depth (Δ = -11%). Moderate to excellent repeatability was observed for all measurements (0.67–0.99).ConclusionsThe present software appears capable to estimate the foot main morphological parameters without the need for skin markers or for identification of anatomical landmarks. Moreover, measurements are not affected by the foot orientation on the scanning device. The good accuracy and repeatability of measurements make the software a potentially useful operator-independent tool for the assessment of foot morphological alterations and for orthotics customization. nAVI may be used for a more realistic classification of foot types when 3D foot images are available.

Translation, cross-cultural adaptation and validation of the Pulmonary Rehabilitation Adapted Index of Self-efficacy (PRAISE) scale for Brazilian patients with chronic obstructive pulmonary disease

Background: Patients with Chronic Obstructive Pulmonary Disease (COPD) present a progressive chronic airflow obstruction. Pulmonary Rehabilitation (PR) promotes the reversal of the extrapulmonary effects of the disease and improves the quality of life. Despite the physiological benefits, the major challenge of PR is to promote change in lifestyle. In this sense, it has been emphasized the study of psychological variables such as self-efficacy. Aim: To translate, cross-culturally adapt and validate the PRAISE scale for Brazilian COPD patients. Methods: The PRAISE scale was applied on the first day by two raters and 15-20 days later by one rater. Patients were assessed for self-efficacy with the General Self-Efficacy Scale (GSS) and the COPD Self-Efficacy Scale (CSES); functional limitation for activities of daily living with the London Chest Activity of Daily Living (LCADL) scale; anxiety and depression symptoms with the Hospital Anxiety and Depression Scale (HADS); quality of life with Saint George’s Respiratory Questionnaire (SGRQ); resilience with the Resilience Scale; and basic psychological needs with the Basic Psychological Needs in Exercise Scale (BPNES). The tests used were: Student’s t-test or Wilcoxon’s test (PRAISE score comparison); intraclass correlation coefficient (ICC), interrater reliability and test-retest and Cronbach’s alpha; and Spearman’s or Pearson’s correlation coefficient to assess validity. Results: The scale was pre-tested in 10 patients to evaluate translation accuracy and cross-cultural adaptation. Thirty-four patients with COPD took part (22 men; FEV1=42.2±15.7%pred). The interrater and test-retest ICCs were excellent (0.82 and 0.86, respectively), with no significant differences in test-retest reliability (p>0.05). Cronbach’s alpha interrater and testretest were 0.90 and 0.92, respectively (p<0.001). There were no floor and ceiling effects. The scale showed weak to moderate correlations with GSS, CSES, LCADL, HADS, SGRQ, Resilience Scale, and BPNES. Conclusions: The PRAISE scale proved to be valid and reliable for Brazilian patients with COPD.

Challenges in the clinical education environment during the outbreak of COVID-19: Development and psychometric testing.

BACKGROUND:COVID-19 pandemic poses unique physical and emotional challenges in providing clinical education. Failure to identify the challenges and problems that students face in the clinical learning environment hinders their effective learning and growth. Consequently, the progress of their skills is affected. The aim of this study was to develop a challenge in the clinical education environment of medical students during the outbreak of COVID-19 questionnaire and to test its psychometric properties.MATERIALS AND METHODS:This study is part of a larger study that was conducted using a combined consecutive method in Qazvin. In the first stage, a phenomenological study was performed with van Manen's method by interviewing 12 students at Qazvin University. To extract the items of the tool in the second stage, the concept was defined. Ultimately, the psychometric properties of the questionnaire were evaluated with face validity, content validity (quantitative and qualitative), construct validity (exploratory factor analysis), internal consistency (Cronbach's alpha), and test–retest reliability (intraclass correlation coefficient).RESULTS:The initial tool had 70 questions. After validation, 53 items remained in the final questionnaire. Four extracted dimensions were as follows: “Inadequate professional competency,” “Inefficient clinical planning” and “outcomes of learning-teaching activities,” and “the challenges related to the stigma of medical staff.” Cronbach's alpha for the whole questionnaire was 0.98 (range: 0.87–0.98). The test–retest (intraclass correlation coefficient) reliability was 0.98 (P < 0.001).CONCLUSIONS:According to the obtained results, if the items of “Inadequate professional competency,” “Inefficient clinical planning” and “outcomes of learning-teaching activities,” and “the challenges related to the stigma of medical staff,” the challenges of students’ clinical education can be reduced during the COVID-19 outbreak.

Development and psychometric property testing of a skin tear knowledge assessment instrument (OASES) in 37 countries.

To develop and psychometrically evaluate a skin tear knowledge assessment instrument (OASES). Prospective psychometric instrument validation study. The skin tear knowledge assessment instrument was developed based on a literature review and expert input (N=19). Face and content validity were assessed in a two-round Delphi procedure by 10 international experts affiliated with the International Skin Tear Advisory Panel (ISTAP). The instrument was psychometrically tested in a convenience sample of 387 nurses in 37 countries (April-May 2020). Validity of the multiple-choice test items (item difficulty, discriminating index, quality of the response alternatives), construct validity, and test-retest reliability (stability) were analysed and evaluated in light of international reference standards. A 20-item instrument, covering six knowledge domains most relevant to skin tears, was designed. Content validity was established (CVI=0.90-1.00). Item difficulty varied between 0.24 and 0.94 and the quality of the response alternatives between 0.01-0.52. The discriminating index was acceptable (0.19-0.77). Participants with a theoretically expected higher knowledge level had a significantly higher total score than participants with theoretically expected lower knowledge (p<.001). The 1-week test-retest intraclass correlation coefficient (ICC) was 0.83 (95% CI=0.78-0.86) for the full instrument and varied between 0.72 (95% CI=0.64-0.79) and 0.85 (95% CI=0.81-0.89) for the domains. Cohen's Kappa coefficients of the individual items ranged between 0.21 and 0.74. The skin tear knowledge assessment instrument is supported by acceptable psychometric properties and can be applied in nursing education, research, and practice to assess knowledge of healthcare professionals about skin tears. Prevention and treatment of skin tears are a challenge for healthcare professionals. The provision of adequate care is based on profound and up-to-date knowledge. None of the existing instruments to assess skin tear knowledge is psychometrically tested, nor up-to-date. OASES can be used worldwide to identify education, practice, and research needs and priorities related to skin tears in clinical practice.

Cross-cultural adaptation and validation of the Spanish version of the Orthognathic Quality of Life Questionnaire for patients with dentofacial deformities

ObjectiveThe aim of this study was to develop a Spanish version of the Orthognathic Quality of Life Questionnaire (OQLQ) that is conceptually equivalent to the original questionnaire, as well as acceptable, reliable, valid, and responsive for use in Chilean patients with dentofacial deformities. Material and methodsThe recommended standard methodology, with direct and back-translation, was used. A prospective longitudinal multicenter study of adult patients diagnosed with dentofacial deformity was carried out, self-administrating OQLQ, OHIP-14 (Oral Health Impact Profile), and SF-36 (Short Form 36 Health Survey) during the presurgery visit in order to examine construct validity. To evaluate reproducibility, questionnaires were re-administered 4 weeks later to subjects with a stable dental condition. Responsiveness was assessed among subjects followed up until 3 months after surgery. ResultsOf the 230 patients under presurgical orthodontic treatment included in the study, 216 completed the questionnaire, 142 formed the reliability sub-sample, and 30 were evaluated 3 months after surgery. Cronbach's alpha ranged from 0.78 to 0.94 and test–retest intraclass correlation coefficients ranged from 0.84 to 0.91 (p = 0.001) by dimension. The correlation matrix between OQLQ dimensions and SF-36 and OHIP-14 confirmed most of the associations previously hypothesized as moderate (rs > 0.4). Confirmatory factor analysis supported the same structure as the original instrument, considering four dimensions. Responsiveness was demonstrated by the large improvement observed in the global score 3 months after surgery: mean change ±SD = −15.1 ± 18.05 and standard response mean = −0.84 (p < 0.001). ConclusionsThe Spanish version of OQLQ has demonstrated good levels of reliability, validity, and responsiveness – similar to those of the original questionnaire.

Reliability and Reproducibility of Neuromelanin-Sensitive Imaging of the Substantia Nigra: A Comparison of Three Different Sequences.

BackgroundNeuromelanin‐sensitive MRI (NM‐MRI) of the substantia nigra provides a noninvasive way to acquire an indirect measure of dopamine functioning. Despite the potential of NM‐MRI as a candidate biomarker for dopaminergic pathology, studies about its reproducibility are sparse.PurposeTo assess the test–retest reproducibility of three commonly used NM‐MRI sequences and evaluate three analysis methods.Study TypeProspective study.PopulationA total of 11 healthy participants age between 20–27 years.Field Strength/Sequence3.0T; NM‐MRI gradient recalled echo (GRE) with magnetization transfer (MT) pulse; NM‐MRI turbo spin echo (TSE) with MT pulse; NM‐MRI TSE without MT pulse.AssessmentParticipants were scanned twice with a 3‐week interval. Manual analysis, threshold analysis, and voxelwise analysis were performed for volume and contrast ratio (CR) measurements.Statistical TestsIntraclass correlation coefficients (ICCs) were calculated for test–retest and inter‐ and intrarater variability.ResultsThe GRE sequence achieved the highest contrast and lowest variability (4.9–5.7%) and showed substantial to almost perfect test–retest ICC (0.72–0.90) for CR measurements. For volume measurements, the manual analysis showed a higher variability (10.7–17.9%) and scored lower test–retest ICCs (–0.13–0.73) than the other analysis methods. The threshold analysis showed higher test–retest ICC (0.77) than the manual analysis for the volume measurements.Data ConclusionNM‐MRI is a highly reproducible measure, especially when using the GRE sequence and CR measurements. Volume measurements appear to be more sensitive to inter/intrarater variability and variability in placement and orientation of the NM‐MRI slab. The threshold analysis appears to be the best alternative for volume analysis.Level of Evidence2Technical Efficacy Stage1

Development and Validation Clinician and Patient Reported Photonumeric Scales to Assess Buttocks Cellulite Severity.

The Clinician Reported Photonumeric Cellulite Severity Scale (CR-PCSS) and Patient Reported PCSS (PR-PCSS) are newly developed tools for assessing cellulite severity. To report on the reliability, validity, and ability to detect a change in cellulite severity on the buttocks of adult women with the CR-PCSS and PR-PCSS. Content validity of both scales was established through concept elicitation and cognitive interviews. Test-retest reliability was evaluated, and intra-rater (both scales) and inter-rater (CR-PCSS only) reliability were estimated using intraclass correlation coefficients (ICCs) for agreement and consistency. Ability to detect a change was determined using the Subject-Global Aesthetic Improvement Scale (GAIS) or Investigator-GAIS as anchors. For the CR-PCSS (n = 6) at baseline and Day 2, the mean interrater ICCs were ≥0.70 and mean intrarater ICCs (95% confidence interval [CI]) were ≥0.81 (0.72-0.90) for both buttocks. For the PR-PCSS (n = 99) at baseline and Day 14, the mean test-retest reliability ICCs (95% CI) were ≥0.86 (0.79-0.91) for both buttocks. A clinically meaningful change was 1.0 point on the PR-PCSS and 1.0 on the CR-PCSS. The CR-PCSS and PR-PCSS reliably assess cellulite severity of the buttocks and can detect a clinically meaningful change after treatment for cellulite.

Cross-cultural adaptation and validation of the Italian Aachener Aphasie Bedside Test (I-AABT), a tool for Aphasia assessment in the acute phase

ABSTRACT Background: Early recognition of post stroke aphasia is thought to be crucial to plan effective rehabilitation. The Aachener Aphasie Bedside Test (AABT) is a widely-used tool for aphasia assessment in acute phase. The AABT was translated into Italian (I-AABT) in 2011, but its psychometric properties had not yet been studied. Aims: The aims of the study were to assess the I-AABT 1) short-term test-retest and inter-rater reliability, 2) concurrent and construct validity, 3) responsiveness and 4) to develop preliminary Italian normative scores to stage aphasia severity.Methods & Procedures: Participants were recruited from three Italian hospitals and divided into four groups: 1) patients with acute aphasia (PwAA; n=116), 2) patients with post-acute aphasia (PwPA; n=54), 3) patients with right-hemisphere damage (PwRHD; n=48) and 4) patients without neurological disorders (PwND; n=30). The I-AABT was administered to all participants. The Aachner Aphasie Test (AAT) was administered to assess concurrent validity. Spearman’s correlations and Intraclass Correlation Coefficient (ICC) were used to calculate reliability. Concurrent and construct validity were assessed through Spearman’s correlations between I-AABT and AAT subscales and Mann-Whitney test, respectively. Wilcoxon signed test was used to assess responsiveness. Both normalized z and T scores were calculated to produce Italian normative scores. Finally, ROC curves were drawn to determine the diagnostic accuracy of the I-AABT Comprehension and Production subtests. Outcomes & Results. Test-retest and inter-rater ICCs were highly significant and strong (ICC > .837, ICC > .698, p<.001, respectively). Correlations between I-AABT and AAT Comprehension and Production subtests were significant and strong (rs>.611, p <.001). Mann-Whitney test confirmed statistically significant difference between PwAA, and both PwRHD and PwND for I-AABT Spontaneous Language, Comprehension and Production subtests. A significant improvement in the I-AABT items Semantic, Phonemic and Syntactic Spontaneous Language, Oral praxis, Object identification, Automatic Language and Naming (p <.05) was detected after intensive language therapy. Preliminary conversion tables were devised to classify comprehension and production impairment levels. I-AABT’s AUC-ROC values for Comprehension and Production parts were significant to detect patients with aphasia with a cut value of 139.5 (sensitivity = 72.9%, specificity = 79.5%9) and 94.5 (sensitivity = 75.2%, specificity = 74.4%.), respectively.Conclusions: The I-AABT proved to be a reliable, valid and responsive tool for the assessment of aphasia in acute stroke patients; its use is recommended in everyday clinical practice.

Cross-cultural adaptation and psychometric testing of the Thai version of the Spinal Cord Independence Measure III-Self Report.

Cross-sectional reliability and validation study. To translate and assess the psychometric properties of the Thai version of the Spinal Cord Independence Measure III-Self Report (TH-SCIM-SR) in Thai spinal cord injury (SCI) patients. Faculty of Medicine Siriraj Hospital, Mahidol University. A cross-cultural forward and backward translation of the original Spinal Cord Independence Measure III-Self Report (SCIM-SR) was performed at the Faculty of Medicine Siriraj Hospital, Mahidol University, Thailand, to create the TH-SCIM-SR. The inclusion criteria were Thai patients with SCI duration of ≥3 months. Patients were evaluated by a team of healthcare professionals using the Thai version of the Spinal Cord Independence Measure Version III (TH-SCIM III). Study patients subsequently completed the TH-SCIM-SR two times with a 3-day interval between evaluations. Cronbach's Alpha, Pearson's correlation coefficient, and intraclass correlation coefficient (ICC) were used to examine internal consistency, concurrent validity, and reliability, respectively. Bland-Altman plot was used to compare scoring results between the TH-SCIM III and the TH-SCIM-SR. Thirty-two patients were included. Cronbach's alpha of total score, self-care subscale, respiration/sphincter management, and mobility subscale were 0.91, 0.94, 0.75, and 0.90, respectively. The reliability analysis showed good reliability. The test-retest ICC of total score, self-care subscale, respiration/sphincter management, and mobility subscale were 0.95, 0.95, 0.78, and 0.96, respectively. Regarding construct validity, the subscales of TH-SCIM-SR demonstrated a strong correlation with those of the TH-SCIM III (0.85-0.96). TH-SCIM-SR showed good reliability and validity for assessing functional independence in Thai patients with SCI.

Understanding and measuring nurses' professionalism: Development and validation of the Nurses' Professionalism Inventory.

To develop a self-report assessment inventory to evaluate nurses' professionalism and test its validity and reliability. Professionalism is essential for nurses' development. To promote professionalism, evaluation indices must be developed. The Nurses' Professionalism Inventory (NPI) was constructed through a literature review and interviews with expert nurses and other medical personnel. An anonymized cross-sectional survey that included this inventory was administered to 5,739 nurses in hospitals throughout Japan. A total of 4,183 (72.8%) questionnaires were returned, of which 3,655 (63.7%) with valid responses were used for further analyses. The Nurses' Professionalism Inventory consists of five subscales containing 28 items: (a) accountability, (b) self-improvement, (c) professional attitude, (d) advancement of the nursing profession and (e) professional membership. The internal consistency reliability (Cronbach's alpha) ranged from 0.84 to 0.90. Confirmatory factor analysis revealed that this five-factor structure had good fit. The test-retest intraclass correlations were consistently greater than 0.6. The Nurses' Professionalism Inventory is valid and reliable. The Nurses' Professionalism Inventory could be used to evaluate changes in nurses' professionalism and programmes designed to promote nurses' professionalism.

Reliability of Different Clinical Techniques for Assessing Foot Posture

ObjectiveThe aim was to determine the interrater and intrarater reliability of navicular drop (NDP), navicular drift (NDT), and the Foot Posture Index-6 (FPI-6), and test–retest reliability of the static arch index (SAI) and dynamic arch index (DAI). MethodsSixty healthy individuals were assessed for intrarater and test–retest reliability. From 60 participants, 30 individuals were assessed for interrater reliability. A digital caliper was used to measure NDP and NDT. Electronic pedography was used to calculate SAI and DAI. The FPI-6 was also performed. All assessments were performed on the dominant foot. The NDP, NDT, SAI, and DAI were repeated 3 times. The NDP and NDT were analyzed separately using both first measurement and the average, but the SAI and DAI were analyzed using only the average. The NDP, NDT, and FPI-6 were conducted by 2 raters to determine interrater reliability and were repeated by a single rater after 5 days from initial assessment to determine intrarater reliability. The SAI and DAI were also repeated after 5 days to determine test–retest reliability. ResultsIntrarater intraclass correlation coefficients (ICCs) were 0.934 and 0.970 for NDP, 0.724 and 0.850 for NDT, and 0.945 for FPI. Interrater ICCs were 0.712 and 0.811 for NDP, 0.592 and 0.797 for NDT, and 0.575 for FPI. Test–retest ICCs of the SAI and DAI were 0.850 and 0.876, respectively. ConclusionNavicular drop is relatively more reliable than other traditional techniques. Also, the FPI-6 has excellent intrarater reliability, but only moderate interrater reliability. The results can provide clinicians and researchers with a reliable way to implement foot posture assessment.

Breast cancer screening beliefs questionnaire: psychometric properties of the Persian version

BackgroundValid and reliable instruments are needed to assess such beliefs, attitudes, and knowledge. This study aimed to translate Breast Cancer Screening Beliefs Questionnaire into Persian and evaluate its psychometric properties among Iranian women.MethodsIn this methodological study, the twelve-item Breast Cancer Screening Beliefs Questionnaire was translated into Persian and filled out by 1256 Iranian women. Face, content, convergent, and discriminant validity were evaluated and exploratory and confirmatory factor analyses were performed for construct validity evaluation. Reliability was also evaluated through calculating Cronbach’s alpha, McDonald’s omega, Average inter-item correlation, and test-retest intraclass correlation coefficient and finally, composite reliability was estimated.ResultsThree factors were extracted in factor analysis which included screening attitude, screening knowledge and perception, and screening practice. These factors explained 55.71% of the total variance of breast cancer screening beliefs. This three-factor model was confirmed in confirmatory factor analysis based on model fit indices (PCFI = 0.703, PNFI = 0.697, CMIN/DF = 2.127, RMSEA = 0.30, GFI = 0.980, AGFI = 0.998, and CFI = 0.991). Convergent and discriminant validity were also confirmed. Composite reliability and test-retest intraclass correlation coefficient were more than 0.7.ConclusionWith a three-factor structure, the Persian Breast Cancer Screening Beliefs Questionnaire has acceptable validity and reliability and hence, can be used to evaluate Iranian women’s breast cancer screening beliefs.

Contact between patients with suicidal ideation and nurses in mental health wards: Development and psychometric evaluation of a questionnaire.

Suicide prevention and treatment opportunities often depend on interpersonal contact between patients and professionals. Presently, there is a lack of valid and reliable instruments to obtain the perspective of patients with suicidal ideation regarding their contact with professionals in mental health wards. This was a three-stage study to develop and psychometrically evaluate a questionnaire: the Contact with Nurses from the perspective of Patients with Suicidal ideation (CoNuPaS). First, the construct was defined by a systematic review, qualitative study, and face validity among experts. Second, the content was validated through a Delphi procedure with professional experts (n=14) and cognitive interviews with hospitalized patients (n=12). Third, using a sample of adult patients with suicidal ideation in the past year (n=405), the psychometric properties were assessed by an exploratory factor analysis, a test-retest procedure, and the internal consistency. The CoNuPaS comprises 23 items and two subsections, to examine patients' perceptions of contact experiences with nurses (CoNuPaS-experience) and what they find important in that contact (CoNuPaS-importance). The subsections comprise four components: encountering a space to express suicidal thoughts and explore needs, being recognized as a unique and self-determining individual, encountering nurses' availability/information-sharing/transparency on expectations, and trusting nurses in communication about suicidality. Content validity scores were excellent (0.78-1.00); test-retest intraclass correlation coefficient and internal consistency were >0.90. Thus, the CoNuPaS demonstrated good psychometric properties. The availability of a valid questionnaire to examine patient-nurse contact in mental health wards is central to improving understanding of nurses' contributions to suicide prevention and suicidal ideation treatment.
