Test-retest Reliability Values Research Articles

Development of an assessment tool for designated medical institutions in China--Based on the application of an online assessment system.

Due to the expanding coverage of medical insurance and the growth of medical expenses, the ability to assess the performance of designated medical institutions (DMIs) in supporting the delivery of high-quality patient care and the standardized use of funds represents a priority in China. Despite such interest, there has yet to be an operable standard and labor-saving method for assessing DMIs in China. The main objectives include two aspects: (1) establishing an evaluation index system for DMIs based on contracts; (2) designing and developing an online evaluation platform. A group of 20 experts with theoretical and practical expertise in medical insurance regulation and performance evaluation were invited to select available indicators. A combination weighting method based on analytic hierarchy process and entropy method was used to determine the weight coefficient. Shanghai was taken as the sample area, and 760 DMIs were included in the empirical research. The test-retest reliability method and criterion-related validity method was used to test the reliability and the validity of the evaluation result. An assessment index system that included 6 domains and 56 indicators was established in this study. Furthermore, we developed an online platform to assist in the implementation of the assessment. The results showed that the average score of assessment was 94.39, the median was 96.92. The test-retest reliability value was 0.96 (P ≤ 0.01), which indicated high stability of the assessment. In addition, there was a significant negative relationship between assessment score and the penalty amount of DMIs (R = -0.133, P < 0.001). After adjusting for the basic characteristics of medical institutions, the number of visits and revenue, the negative relationship was still significant (B = -0.080, P < 0.05). These results are consistent with expectations, indicating that the assessment had good criterion-related validity. This study established an operable assessment measure and developed an online platform to assess the performance of DMIs. The results showed good feasibility and reliability in empirical research. Our research findings provided an operable Chinese solution for DMI assessment that saves manpower and time, which would have good enlightening significance in other regions of China and in low-income and middle-income countries internationally.

Psychometric analysis of the International Olympic Committee's Sport Mental Health Assessment Triage Tool among non-elite amateur adult athletes

ABSTRACT Background The International Olympic Committee developed the Sport Mental Health Assessment Tool-1, encompassing the Athlete Psychological Strain Questionnaire (APSQ) – used for initial screening of mental ill-being symptoms and risk in elite athletes. Despite preliminary psychometric evidence, the APSQ has yet to be tested in non-elite amateur athletes, who represent the majority of sporting participants. Method Athletes (n = 605) aged 28.57 years (SD = 9.32) comprising 402 males (73.5%) completed the 10-item APSQ, alongside validated measures of anxiety, depression and well-being. Two Confirmatory Factor Analysis models were tested, in addition to a series of receiver operating characteristics curves benchmarked against clinically relevant anxiety and depression symptoms to examine pre-defined and alternative cut-point sensitivity values. Nomological validity was tested through Pearson's correlations, and intraclass correlation coefficients were examined for test–retest reliability. Results A higher-order APSQ model comprising a general “Psychological Strain” factor, and three subcomponents of “External coping”, “Self-Regulation” and “Performance” were selected. Convergent and divergent validity were shown, and a new revised cut-point was found to have good classification accuracy within the sample. Largely “fair-to-good” test–retest reliability values were found. Conclusion The APSQ could be considered for initial screening of athlete mental health symptoms by sports organisations and may enable effective triaging to follow-up mental health assessment and/or supporting guidance, potentially preventing, or mitigating, short and long-term effects of mental ill-being. Further research should be undertaken to establish if the psychometric properties found amongst the present sample are generalisable to the broader amateur sporting population.

Extending the Range of Measurement for Minimally Invasive Treatments by Adding New Concepts to FACE-Q Aesthetics Scales.

The Satisfaction with Face Overall and Psychological Function scales are the most frequently used FACE-Q Aesthetics module scales. This study aimed to extend their range of measurement by adding and testing new concepts. We aimed to create FACE-Q Aesthetics item libraries. In-depth concept elicitation interviews were conducted. Concepts were formed into items and refined through multiple rounds of patient and expert input. The items were tested with people living in the United States, Canada, and the United Kingdom who had minimally invasive facial aesthetic treatments. Participants were recruited through an online platform (ie, Prolific). Psychometric properties were examined using Rasch measurement theory analysis, test-retest reliability, and construct validity. We conducted 26 interviews. New concepts were developed into items and refined with input from 12 experts, 11 clinic patients, and 184 Prolific participants. A sample of 1369 Prolific participants completed 52 appearance and 22 psychological items. After removing 10 and 2 items respectively, the psychometric tests provided evidence of reliability with the person separation index, Cronbach alpha, and test-retest reliability values without extremes of 0.88 or more. For validity, lower scores were associated with looking older than one's age, being more bothered by facial skin laxity, treatment wearing off, and having deeper lines on Merz Assessment scales. Short-form scales formed from the 42 appearance items provide examples of item library application. This study provides an innovative means to customize scales to measure appearance and psychological function that maximizes content validity and minimizes respondent burden in the context of minimally invasive treatments.

Preliminary Characterization of Age and Chronic Low Back Pain Effects on Multimodal Pain Sensitivity: A Comparison Study in Older Adults with and Without Chronic Low Back Pain

Though pain sensitivity impairments contribute to chronic pain in younger adults, it is unclear if pain hypersensitivity manifests with aging and is heightened in the geriatric chronic low back pain population. The cross-sectional study preliminarily addressed this gap by measuring pain sensitivity in older adults with chronic low back pain (n = 25) as well as pain-free sex-matched older (n = 25) and younger adults (n = 25). Pain sensitivity was quantified by 8 distinct measures that were subdivided as static (ie, pressure pain thresholds, heat pain thresholds, fixed mechanical pain, and fixed cold pain) and dynamic pain sensitivity (ie, mechanical temporal summation, thermal ramp and hold, heat pain aftersensations, and conditioned pain modulation). Test-retest reliability values for pain sensitivity ranged from moderate to excellent (intraclass correlation coefficients ≥ .500; p’s < .05). The main effect for the group was significant (partial η2 = .413, P < .001), revealing between-group differences in pain sensitivity on 5 out of 8 tests (p’s ≤ .043). Predominantly, both older adult groups demonstrated increased pain facilitation and decreased pain inhibition during dynamic pain sensitivity testing compared to pain-free younger adults (p’s ≤ .044). Despite qualitative differences, static and dynamic pain sensitivity responses were statistically similar between older adults with and without chronic LBP (p’s > .05). Findings suggest pain sensitivity can be reliably measured in older adults and that pain hypersensitivity develops with chronological aging, providing partial support for the theory that pain hypersensitivity may impact geriatric chronic pain populations. Further study is needed to more definitively parse out whether pain hypersensitivity is comparatively heightened in older adults with chronic LBP beyond the influence of chronological aging. PerspectiveThis article establishes that surrogate measures of centrally mediated pain sensitization are heightened with aging. Impaired endogenous pain modulation may influence chronic pain development, maintenance, treatment efficacy, and/or ensuing disability, necessitating research to comprehensively characterize how pain hypersensitivity contributes to geriatric chronic pain conditions.

Sinhala version of the Cornell Musculoskeletal Discomfort Questionnaire: Cross-cultural adaptation and validation.

Work-related musculoskeletal disorders (WMSDs) are highly prevalent among people who work in sedentary jobs. The Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) is a valid tool to assess WMSDs, but is not available in the local language of Sri Lanka (Sinhala). To cross-culturally adapt the original CMDQ from English to Sinhala and evaluate its psychometric properties. The linguistic and cultural adaptation of the CMDQ to the Sinhala (Si-CMDQ) language followed international guidelines. The adapted pre-version was tested for comprehensibility among 32 subjects from different educational and occupational backgrounds. The Content Validity Index (CVI) was computed with ratings from five experts. The questionnaire was validated further by 111 security guards employed at the university. The tool was validated with reference to the Numeric Rating Scale. Test-retest reliability was assessed at two time points one week apart and internal consistency was tested. The Si-CMDQ showed adequate cross-cultural, content and construct validity, internal consistency, and test-retest reliability. The Kappa coefficient showed excellent agreement between NRS and Si-CMDQ frequency scale. Spearman's correlation coefficients showed a moderate to a strong significant positive correlation between NRS and the severity scale of Si-CMDQ. The Kappa values for test-retest reliability were moderate to excellent for the three scales of CMDQ. The internal consistency was high. The Si-CMDQ fulfilled the psychometric requirement for questionnaires. This tool will be beneficial to assess WMSDs among sedentary workers in different occupations in Sri Lanka.

Validity and Reliability Study of the Turkish Version of Focus on the Outcomes of Communication Under Six-34.

Speech and language disorders can negatively affect preschool children's communicative participation skills. Focus on the Outcomes of Communication Under Six-34 (FOCUS-34) is a valid and reliable scale that evaluates communicative participation in preschool children with speech and language disorders. This study aimed to establish the Turkish version of FOCUS-34 (FOCUS-34-TR) and investigate its validity and reliability. A total of 175 children with language disorders, speech sound disorders, and fluency disorders (aged 20-72 months) and their parents were included in the study. Parents were asked to complete the demographic information form, the FOCUS-34-TR scale, and the Ages and Stages Questionnaires: Social-Emotional (ASQ-SE) Turkish version. The construct validity, convergent and divergent validity, internal consistency, and test-retest reliability of the scale were investigated. The FOCUS-34-TR had high values for internal consistency (α = .97) and test-retest reliability (r = .95). The correlations between the FOCUS-34-TR total score and its subscales were between .77 and .90. A moderately significant negative correlation was found between the FOCUS-34-TR scale and the ASQ-SE. The Turkish version of FOCUS-34 is a valid and reliable scale that can be used in clinics and for research purposes to evaluate the communicative participation skills of Turkish-speaking preschool children with speech and language disorders.

The Revised Second Victim Experience and Support Tool: Thai Translation and Psychometric Evaluation.

Background and Purpose: Nurses are vulnerable to being second victims, resulting in physio-psychological problems and leaving their profession. Exploring second victims requires reliable instruments. This study aimed to translate the Revised Second Victim Experience and Support Tool (SVEST-R) and evaluate its psychometric properties. Methods: The translation process applied the World Health Organization guidelines and validated the Thai version of the SVEST-R (Thai-SVEST-R) with 400 registered nurses. Results: Part A of the scale had a highly constructed validity with a significantly good model fit and was equivalent to the original SVEST-R. For Part B, the test-retest reliability value was satisfactory. Conclusions: Thai-SVEST-R demonstrates evidence of validity and reliability, indicating the scale's value for measuring Thai nurses' experiences as second victims.

Unveiling the relationships between eco-anxiety, psychological symptoms and anthropocentric narcissism: The psychometric properties of the Turkish version of the Hogg eco-anxiety scale

Abstract The increasing number of losses and damages caused by the climate crisis has rendered the psychometric assessment of the climate crisis more important than ever, specifically in developing countries, such as Turkey. The aim of this study was to examine the psychometric properties of the Turkish version of the Hogg Eco-Anxiety Scale (HEAS-13), using exploratory structural equation modeling (ESEM) on the cross-sectional data collected from 445 adults (286 females and 159 males; Mage = 29.76, range 18–65). The results supported the four-factor solution of the original version in the Turkish sample. Further analysis confirmed the invariance of the HEAS-13 across genders. The results demonstrated significant correlations of the HEAS-13 subscales with the Brief Symptom Inventory (BSI) and the Anthropocentric Narcissism Scale (ANS), except for that between the behavioral symptoms subscale of the HEAS-13 and the ANS. Both the total and the subscale scores of the HEAS-13 were also found to be reliable, given the internal consistency and test–retest reliability values. The Turkish version of the HEAS-13 can expand the scientific understanding of eco-anxiety, which can help develop mental health services to mitigate the negative mental health impacts of the environmental crisis.

Adaptation and Validation of the Mandarin Chinese Version of the Pediatric Voice Handicap Index-10 (pVHI-10).

The purpose of this study was to adapt and validate the Mandarin Chinese version of the pediatric Voice Handicap Index-10 (pVHI-10). A cross-sectional study was conducted from January 2018 to December 2019. A total of 422 parents completed the questionnaire, including 283 parents of children with voice disorders (dysphonic group) and 139 parents of children without voice disorders (control group). Internal consistency, test-retest reliability, clinical effectiveness, and cut-off value were evaluated. In the dysphonic group, the internal consistency of the Mandarin Chinese version of pVHI-10 was excellent (Cronbach's α=0.95). The test-retest reliability was excellent for the total score of the Mandarin Chinese version of pVHI-10 (interclass correlation coefficient=0.916). The total scores as well as scores on individual items were significantly higher in the dyphonic group compared to those in the control group (P <0.001). In addition, the optimum cut-off value for the Mandarin Chinese version of pVHI-10 was 6.5 (87% sensitivity and 86.3% specificity, respectively). The Mandarin Chinese version of the pVHI-10 is a valid tool that evaluates the quality of life of children with voice disorders from the parents' perspective.

Multi-Site Cross-Site Inter-Rater and Test-Retest Reliability and Construct Validity of the MarkVCID White Matter Hyperintensity Growth and Regression Protocol.

White matter hyperintensities (WMH) that occur in the setting of vascular cognitive impairment and dementia (VCID) may be dynamic increasing or decreasing volumes or stable over time. Quantifying such changes may prove useful as a biomarker for clinical trials designed to address vascular cognitive-impairment and dementia and Alzheimer's Disease. Conducting multi-site cross-site inter-rater and test-retest reliability of the MarkVCID white matter hyperintensity growth and regression protocol. The NINDS-supported MarkVCID Consortium evaluated a neuroimaging biomarker developed to track WMH change. Test-retest and cross-site inter-rater reliability of the protocol were assessed. Cognitive test scores were analyzed in relation to WMH changes to explore its construct validity. ICC values for test-retest reliability of WMH growth and regression were 0.969 and 0.937 respectively, while for cross-site inter-rater ICC values for WMH growth and regression were 0.995 and 0.990 respectively. Word list long-delay free-recall was negatively associated with WMH growth (p < 0.028) but was not associated with WMH regression. The present data demonstrate robust ICC validity of a WMH growth/regression protocol over a one-year period as measured by cross-site inter-rater and test-retest reliability. These data suggest that this approach may serve an important role in clinical trials of disease-modifying agents for VCID that may preferentially affect WMH growth, stability, or regression.

Persian Handwriting Assessment Tool: Reliability in Students with Specific Learning Disorders

Background: Handwriting is one of the most common reasons for referral to occupational therapy among children with specific learning disorders (SLDs). The Persian handwriting assessment tool (PHAT) is a valid assessment instrument. It is important to clarify the reliability of this assessment tool for the accuracy of results and certain clinical uses in Iranian children with SLDs. Objectives: The present study aimed to investigate the internal consistency, test-retest, and inter-rater reliability of the PHAT in children with SLDs aged 10 to 12 years in the Iranian context. Methods: Thirty children (mean ± SD 132.33 ± 53.8 months) with SLDs, studying in grades 4 to 6, were recruited from special education schools and rehabilitation clinics from January to May 2022. Cronbach's alpha and intraclass correlation coefficient (ICC) were calculated to determine internal consistency, test-retest reliability, and inter-rater reliability, respectively. The standard error of measurement (SEM) and minimal detectable change (MDC) were computed to establish absolute reliability. Results: Internal consistency was excellent (α = 0.98 to 0.99), as was inter-rater reliability (ICC = 0.95 to 1.00). Test-retest reliability was good to excellent (0.86 to 1.00). The SEM and MDC values for test-retest reliability were 0 to 0.47 and 0 to 1.29, respectively. Finally, the SEM (0 - 0.21) and MDC (0 - 0.57) values were acceptable for inter-rater reliability. Conclusions: The PHAT is a reliable assessment tool for Iranian children with SLDs aged 10 to 12 years. Further, clinicians can utilize this tool to identify handwriting difficulties in children with SLDs aged 10 to 12 years, which leads to more targeted interventions.

Trust Your Fingers: Determining the Reliability and Validity of the Measurement of the Diastasis of the Rectus Abdominis Muscle by Palpation and Tape Measure

Background: Diastasis of the rectus abdominis muscle (DRAM) occurs in about 60% of pregnant women and often persists after delivery. Currently, the reference standard to measure DRAM is ultrasonography, and physiotherapy is considered first-line treatment. Most physiotherapists do not base their DRAM assessment on ultrasonography but instead on palpatory evaluation with tape measures. This method is neither standardized nor has been tested for its reliability or validity in women with interrectus distance (IRD) of 30 mm and greater. Objectives: To assess the reliability of the measurements of DRAM by palpation with tape measure and to evaluate its validity compared with ultrasonography. Study Design: Prospective observational study. Methods: Two physiotherapists assessed test-retest, intra- and interrater reliability of this method in 20 women with IRD of 30 mm and greater, using intraclass correlations (ICC) and compared the values with ultrasonography to establish its validity using Spearman ρ and Bland-Altman plots. The interval between the 2 sessions was 7 days and greater. Results: The ICC values for test-retest reliability ranged from 0.67 to 0.95 and between 0.40 and 0.85 for intrarater reliability. The ICC values for interrater reliability ranged from 0.13 to 0.29. In terms of validity, correlations were inconsistent with Spearman ρ ranging from −0.24 to 0.74. Conclusion: Single palpatory measurement with tape above the umbilicus and during partial curl-up might detect changes in IRD of 15.5 mm and greater over time in women with IRD of 30 mm and greater. It cannot replace ultrasonographic measurements in accuracy but might be the only available option for IRDs larger than the ultrasonographic probe.

Transcultural adaptation, content, and internal structure validity evidence of the perceived efficacy and goal setting system - 2 edition for Brazilian children.

AimThe aim was to investigate the validity of evidence of the Perceived Efficacy and Goal Setting System second edition for Brazilian children.Methods258 children participated, both sexes (n = 133 girls; 51.6%), 5 to 9 years old (total sample Mage = 7.1, SD = 1.4), from four regions of Brazil. The Perceived Efficacy and Goal Setting System – second edition, was used.ResultsExperts showed agreement about the high clarity and practical pertinence of the items (content validity coefficient from 98.4 to 100%; Gwet’s agreement coefficient from 0.85 to 1.00, p &amp;lt; 0.001). Confirmatory factorial analysis showed adequate adjustment indexes (RMSEA [0.048, 90% C.I. = 0.043 to 0.053], SRMR [0.243], CFI [0.91], RNI [0.91], TLI [0.91], ꭓ2/df [1.962]). The multigroup analysis showed configural, metric and scalar invariance of two models for gender (CFI = 0.97; RMSEA, [90%C.I.] = 0.05 [0.03 to 0.07]; metric: ΔRMSEA = 0.001; scalar: ΔRMSEA = −0.004) and age band (5–7 years-old and 8–9 years-old; CFI = 0.94; RMSEA, [90%C.I.] = 0.05 [0.03 to 0.07]; metric: ΔRMSEA = 0.002; scalar: ΔRMSEA = 0.010). The Heterotrait-Monotrait ratio test showed adequate discriminant validity among three dimensions (self-care and productivity [value = 0.76]; self-care and leisure [value = 0.57], productivity and leisure [value = 0.76]). Alpha for polychoric correlations showed an adequate internal consistency for all items and total scale (all α values &amp;gt;0.70). Composite reliability (Self-care = 0.8; Productivity = 0.81; Leisure = 0.8) reinforce evidence about reliability. Percentage agreement showed adequate item-level test-retest reliability (values between 76 and 92%).ConclusionThis scale showed adequate content and internal structure validity evidence to assess the perceived self-efficacy for Brazilian children.

The Oxford Face Matching Test: Short-form alternative.

A recently published test of face perception, the Oxford Face Matching Test, asks participants to make two judgements: whether two faces are of the same individual and how perceptually similar the two faces are. In this study, we sought to determine to what extent the test can be shortened by removing the perceptual similarity judgements and whether this affects test performance. In Experiment 1, participants completed two versions of the test, with and without similarity judgements, in separate sessions in counterbalanced order. The version without similarity judgements took approximately 40% less time to complete. Performance on the matching judgements did not differ across versions and the correlation in accuracy across the two versions was comparable with the originally reported test-retest reliability value. Experiment 2 validated the version without similarity judgements against other measures, demonstrating moderate relationships with other face matching, memory, and self-report face perception measures. These data indicate that a test version without the similarity judgements can substantially reduce administration time without affecting test performance.

An evaluation of the test-retest reliability of the functional head impulse test in healthy young adults.

To determine the test and retest reliability of the functional head impulse test (fHIT) in healthy young adults. Thirty-three healthy participants (17 women, 16 men) aged 18-30years were included in the study. Each participant underwent the fHIT twice, 1week apart, by the same experienced clinician. Intraclass correlation coefficients (ICCs) were used to determine test-retest reliability. There was no statistically significant difference between the results of total percentage of correct answer (CA%) of the fHIT obtained in session 1 and session 2 measurements in the lateral, anterior, and posterior semicircular canals (SCCs) (p > 0.05). ICC values for test-retest reliability were found to range from 0.619 to 0.665 for the three semicircular canals (SCCs). The test-retest reliability of the fHIT device was moderate. Attention, cognition, and fatigue may be the factors reducing reliability. In the diagnosis, follow-up, and rehabilitation processes of vestibular diseases in clinics, changes in the fHIT CA% can be used to assess vestibulo-ocular reflex (VOR) functionality.

An instrument to measure atrial fibrillation knowledge in Chinese patients: validation of the Jessa Atrial fibrillation Knowledge Questionnaire.

Background: There is no validated tool to assess patients' knowledge of oral anticoagulant therapy in atrial fibrillation in China. Methods: Using a standard translation program, the Jessa Atrial fibrillation Knowledge Questionnaire (JAKQ) was translated into Chinese. The reliability of the JAKQ was assessed by internal consistency (Cronbach's α coefficient), repeatability (test-retest reliability), and sensitivity tests. Effectiveness was assessed by hypothesizing that a lower JAKQ score was a risk factor for bleeding. A total of 447 patients with atrial fibrillation (AF) who were hospitalized between July 2019 and December 2021 were studied and followed up. Participants were followed up 1, 3, 6, and 12 months after enrollment. Bleeding during follow-up was recorded. Data were obtained from hospital databases and telephone follow-up. Result: A total of 447 patients with AF completed JAKQ. The mean age of patients was 67.7 ± 10.2years. The median JAKQ score was 31.3% (12.5-43.8). The Cronbach's α coefficient of JAKQ was 0.616-0.637, and the test-retest reliability value was 0.902 (p < 0.001). Multivariate logistic regression showed that the higher knowledge level of AF was associated with secondary education or above, an income of more than 2000 yuan, and a history of AF of more than 1year. Bleeding was associated with a lower JAKQ score, hypertension, and a history of bleeding. Non-bleeding patients on VKA had a better understanding of how often INR should be monitored and what to do if an OAC dose was missed. Conclusion: The Chinese version of JAKQ shows good reliability and validity, indicating that it is a valuable tool for AF and oral anticoagulation (OAC) knowledge assessment. It can be used in clinical practice to guide educational activities and improve the effectiveness and safety of treatment. It was shown that Chinese patients with AF have insufficient knowledge about AF and OAC. Lower JAKQ scores are associated with bleeding, so targeted education is necessary. Targeted educational efforts should focus on patients recently diagnosed with AF and those with lower formal education and income.

Translation, Cultural Adaptation, and Reliability of the 15D Portuguese Version: A Generic Health-Related Quality of Life (HRQoL) Instrument.

(1) Background: Purpose: The assessment of quality of life is essential to the human condition and can be measured through questionnaires. This study aims to translate and culturally adapt the 15D questionnaire to assess the population's quality of life, as well as explore its relative reliability and internal consistency; (2) Methods: The translation and cultural adaptation of the 15D questionnaire was carried out independently, considering two translations. The synthesis version was applied to eight subjects, distributed by gender. Cognitive interviews were conducted to observe clarity, acceptability, and familiarity with the version of the questionnaire. The final version of the questionnaire, in Portuguese, was again translated into the official language by two translators who had never had contact with the questionnaire. To assess the test-retest reliability and internal consistency of the 15D questionnaire, 43 participants were interviewed; (3) Results: Participants indicated that they had some doubts about dimensions, breathing, and discomfort and symptoms; however, as there were no suggestions for change, the questionnaire had no changes. Items were clear and understandable. Internal consistency was observed using Cronbach's alpha, with values between 0.76 and 0.98. The test-retest reliability values were between 0.77 and 0.97; and (4) Conclusions: The Portuguese version of the 15D questionnaire was proved to be equivalent to the English version and to be reliable for the Portuguese population. This instrument is easy to access and apply.

A Novel Device for Assessment and Treatment of Upper Cervical Spine: Test–Retest Reliability Study

Neck pain is one of the most frequent reasons for consultation in primary care. Clinicians evaluate different variables, including movement and cervical strength, to determine the prognosis of patients. Usually, the tools employed for this purpose are expensive and bulky, or more than one is needed. This study aims to describe a novel device designed to assess the cervical spine and describe its test-retest reliability. The Spinetrack device was designed to measure the strength of deep cervical flexor muscles and the chin-in and chin-out movement of the upper cervical spine. A test-retest reliability study was developed. The flexion, extension and strength needed to move the Spinetrack device were registered. Two measurements were developed, with one week between each assessment. Twenty healthy subjects were evaluated. The strength of the deep cervical flexor muscles in the first measurement was 21.18 ± 3.15 Newtons, the displacement movement during chin-in movement was 12.79 mm ± 3.46 and the displacement during chin-out movement was 35.99 mm ± 4.44. The test-retest reliability of strength was ICC 0.97 (95% CI (0.91-0.99)). The Spinetrack device has shown excellent test-retest reliability values for the measurement of the strength of the cervical flexor muscles and for the chin-in and chin-out movements.

Test-Retest Reliability and Minimum Difference Values of a Novel and Portable Upright Row Strength Assessment in Probation Officers.

Upper body (UB) strength is important for occupational tasks and injury prevention in law enforcement officers (LEOs). Portable, reliable, and cost-effective assessments are needed to examine UB strength among LEOs in field settings. The purpose of this study was to examine the test-retest reliability and minimum difference (MD) values of a novel and portable isometric upright row assessment in probation officers. Thirty certified probation officers (18 women; age = 38.9 ± 9.0 years, body mass = 98.8 ± 27.1 kg, stature = 171.4 ± 14.0 cm) volunteered for this investigation. Testing occurred on-site across two sessions (2-5 days apart). Participants stood upon an aluminum plate with a chain attached to a handle and dynamometer. They grasped the handle with a pronated grip, two cm below the umbilicus, and performed three isometric maximal voluntary contractions. Intraclass correlation coefficient (ICC2,1), standard error of the measurement (SEM), and MD values were calculated. Results indicated no significant systematic error (p = 0.080) across sessions. The ICC2,1, SEM, and MD values for UB strength were 0.984, 27.20 N (4.1% of the mean), and 75.38 N (11.3% of the mean), respectively. These data suggest this isometric upright row assessment is a reliable, portable, and cost-effective measure of UB strength to assess and monitor LEOs in field settings.

Psychometric evaluation of the Chinese version of fear of hospitalization scale among outpatients: A validation study.

In China, some patients avoid seeking medical care and are highly sensitive to subsequent medical care because of fear of possible hospitalization after a diagnosis has been established. Early identification of fear of hospitalization is essential for clinical staff to develop targeted education and interventions. However, there are currently no tools to assess outpatients' fear of hospitalization in mainland China. This study aimed to translate the Fear of Hospitalization (FH) scale into Chinese and verify its reliability and validity in outpatients. Through convenience sampling, 664 outpatients who required hospitalization were recruited from two cities in Liaoning Province, China. The reliability of the translated scale was measured by internal consistency, split-half reliability, and test-retest reliability. The validity of the translated scale was evaluated by expert consultation, exploratory factor analysis, and confirmatory factor analysis. Data were analyzed using SPSS 25.0 (IBM Corp., Armonk, NY, United States) and AMOS 23.0 (IBM Corp., Armonk, NY, United States). The Cronbach's α value of the Chinese version of the FH scale was 0.849, and the Cronbach's α value of the dimensions ranged from 0.857 to 0.902. The test-retest reliability value of 0.868 shows good temporal stability. The split-half reliability value of 0.910 indicates a high degree of measuring the same content. The content validity index of the scale (S-CVI) was 0.924, indicating a good level of content validity. The 3-factor structure supported by eigenvalues, total variance explained, and scree plot was obtained using exploratory factor analysis. In addition, all recommended fit indicators were within the acceptable range by confirmatory factor analysis. The Chinese version of the FH scale is valid and reliable in outpatients. The developed three-factor structured scale will help identify outpatients with a high fear of hospitalization and can inform the development of educational intervention plans for care managers, physicians, and nurses. In addition, it helps clinicians and nurses take action to reduce this fear of hospitalization in patients and prevent avoidance of using health care services due to fear of hospitalization.
