Abstract Background The thermal strain can be measured using subjective methods without the use of sensitive equipment. The purpose of the present study was the development and validation of an observational - perceptual heat strain risk assessment (OPHSRA) method. Methods This cross-sectional study, in 2019, was performed. At first, an observational-perceptual questionnaire was designed using effective items in producing heat strain. Then, the reliability and validity of the questionnaire were examined. Later, 201 male workers were asked to perform the routine tasks for 90 min under various climatic conditions after resting in a cool room. At the end of the activity, the tympanic temperature of the subjects was accurately measured. Also, the designed questionnaire was completed by researchers and participants. Then, the effect coefficients of the items were calculated and used for developing the novel index. At final, the index validity was investigated. Results The values of the content validity ratio (CVR), content validity index (CVI), and Cronbach’s coefficient alpha (α) of the designed questionnaire with 16 questions were equal to 0.793, 0.913, and 0.910, respectively. The results indicated that environmental, job, administrative, and clothing items assessed by the questionnaire with the coefficients of 0.860, 0.658, 0.783, and 0.566 had significant effects on the thermal strain, respectively. These coefficients were exploited to develop the index. The result revealed that the OPHSRA index justified 69% of the variations of the tympanic temperature (R2 = 0.69). Conclusion The novel index developed by the questionnaire had an acceptable validity. Therefore, this index can be used for estimating the risk of thermal strain in a variety of thermal conditions.

Background and Purpose: The purpose of this study was to assess the psychometric properties of the Survey of Workplace Intimidation (SWI), including content and construct validity, factor structure, and internal consistency. Methods: A cross-sectional, descriptive study design was used for this study. The final sample consisted of 237 labor and delivery nurses who completed the SWI and the Practice Environment Scale of the Nursing Work Index (PES-NWI). Cronbach's alpha for the SWI was .930. Results: Content validity was obtained and the scale content validity index (S-CVI) was .943. Convergent validity was calculated by comparing the SWI with the PES-NWI, and the result was .408 (p .01). A factor analysis explained 61% of the variance and resulted in two factors: prescriber behaviors and nurses' responses to prescribers' behaviors. Conclusions: The SWI demonstrated acceptable reliability and validity.

Background: Prosthetists and orthotists have a responsibility to direct treatment toward enabling their clients to perform desired activities and to facilitate participation of their clients in all areas of life. This may include provision of assistive technologies to help clients meet goals related to participation in sexual activities. To help prosthetic and orthotic students develop competencies in dealing with the sexual health of their future clients, it is necessary to generate knowledge of their own perceived competence and capacity. Objectives: To explore prosthetic and orthotic students’ attitudes and competence toward working with sexual health and to evaluate reliability and validity of the Students’ Attitudes Towards Addressing Sexual Health questionnaire. Study design: Cross-sectional study. Methods: Students enrolled in all three years of an undergraduate prosthetic and orthotic program were requested to complete the Students’ Attitudes Towards Addressing Sexual Health questionnaire ( n = 65). Reliability and validity were evaluated using the content validity index and Cronbach’s alpha. Results: Students felt unprepared to talk about sexual health with future clients and thought that they would be embarrassed if they raised the issue. No differences were identified between students enrolled in each of the three years of the program and few differences were observed between male and female students. The content validity index values were low but improved as the students’ level of education increased. Internal consistency of the questionnaire was acceptable ( α = 0.86). Conclusion: Prosthetic and orthotic students are unprepared to address sexual health issues with their future clients. There is a need to provide students with training related to sexual health issues. Clinical relevance This study indicates the need for additional education of prosthetic and orthotic students in issues related to sexual health and how to address sexual health issues with clients. Results can be used to develop training programs for students and will serve to improve the sexual health of individuals who receive prosthetic and orthotic services.

Abstract Background: This study aims to develop a risk assessment scale to assess and quantify risk of hepatic encephalopathy in cirrhotic patients. Methods: Data were derived from two Delphi rounds and a cross-sectional survey of 276 cirrhotic patients. The minimal consensus were a mean score 3.5 on a scale of 1 to 5, and a coefficient of variation 0.25. The reliability and validity of the scale were validated by a cross-sectional survey. Results: After two Delphi rounds and item analysis, a final 23-item scale covered two dimensions. The total Cronbach’s αretest Cronbach’s α, interrater Cronbach’s α and split-half Cronbach’s α were higher than 0.7, showing an acceptable reliability. The AUC was 0.792, and the sensitivity and specificity were 83.9% and 59.6%, respectively, indicating that the scale had a good predictive validity. Conclusion: This scale may be a promising tool for estimating and ranking risk of hepatic encephalopathy. Future research is necessary to apply it in hepatic encephalopathy.

The Ten Item Personality Inventory (TIPI; Gosling, Rentfrow, & Swann, 2003 ) is a widely used very brief measure of the Big Five personality dimensions. Oshio, Abe, and Cutrone (2012) have developed a Japanese version of the TIPI (TIPI-J), which demonstrated acceptable levels of reliability and validity. Until now, all studies examining the validity of the TIPI-J have been conducted in the Japanese language; this reliance on a single language raises concerns about the instrument’s content validity because the instrument could demonstrate reliability (e.g., retest) and some forms of validity (e.g., convergent) but still not capture the full range of the dimensions as originally conceptualized in English. Therefore, to test the content validity of the Japanese TIPI with respect to the original Big Five formulation, we examine the convergence between scores on the TIPI-J and scores on the English-language Big Five Inventory (i.e., the BFI-E), an instrument specifically designed to optimize Big Five content coverage. Two-hundred and twenty-eight Japanese undergraduate students, who were all learning English, completed the two instruments. The results of correlation analyses and structural equation modeling demonstrate the theorized congruence between the TIPI-J and the BFI-E, supporting the content validity of the TIPI-J.

Abstract Objective Rating tissue irritability has been recommended to aid decision making in several recent clinical practice guidelines. An explicit method for rating tissue irritability was proposed as part of the Staged Algorithm for Rehabilitation Classification: Shoulder Disorders (STAR-Shoulder), but the reliability and validity of this classification are unknown. The purpose of this study was to examine the reliability and concurrent validity of shoulder tissue irritability ratings as part of a system designed to guide appropriate treatment strategy and intensity. Methods A clinical measurement, prospective repeated-measures cross-sectional design was used. The 101 consecutive participants with primary complaints of shoulder pain were assessed by pairs of blinded raters (24 raters in total) and rated for tissue irritability. Patients completed 3 patient-rated outcome (PRO) measures reflecting both pain and disability, and these scores were compared with ratings of tissue irritability. Paired ratings of irritability were analyzed for reliability with prevalence-adjusted, bias-adjusted Kappa for ordinal scales (PABAK-OS). Analysis of variance (ANOVA) was used to compare PRO measures across different levels of irritability. Receiver operating characteristic (ROC) curve analysis was utilized to derive cut-off scores for 3 PRO instruments. Results Interrater reliability was 0.69 (95% CI = 0.59–0.78), with 67% agreement. All PRO measures were significantly different among 3 levels of tissue irritability. Conclusion There appear to be acceptable reliability and a strong relationship between PRO measures and therapist-rated tissue irritability, supporting the use of the STAR-Shoulder irritability rating system. Impact Several clinical practice guidelines have recommended that clinicians rate tissue irritability as part of their examination. This study provides important new information supporting the reliability and validity of the STAR-Shoulder tissue irritability rating system.

PurposeTo translate and adapt the Chelsea Critical Care Physical Assessment Tool (CPAx) into Chinese version (‘CPAx-Chi’), test the reliability and validity of CPAx-Chi, and verify the cut-off point for the diagnosis of intensive care unit-acquired weakness (ICU-AW).Study designCross-sectional observational study.MethodsForward and back translation, cross-cultural adaptation and pretesting of CPAx into CPAx-Chi were based on the Brislin model. Participants were recruited from the general ICU of five third-grade class-A hospitals in western China. Two hundred critically ill adult patients (median age: 53 years; 64% men) with duration of ICU stay ≥48 hours and Glasgow Coma Scale ≥11 were included in this study. Two researchers simultaneously and independently assessed eligible patients using the Medical Research Council Muscle Score (MRC-Score) and CPAx-Chi.ResultsThe content validity index of items was 0.889. The content validity index of scale was 0.955. Taking the MRC-Score scale as standard, the criterion validity of CPAx-Chi was r=0.758 (p<0.001) for researcher A, and r=0.65 (p<0.001) for researcher B. Cronbach’s α was 0.939. The inter-rater reliability was 0.902 (p<0.001). The area under the receiver operating characteristic curves of CPAx-Chi for diagnosing ICU-AW based on MRC-Score ≤48 were 0.899 (95% CI 0.862 to 1.025) and 0.874 (95% CI 0.824 to 0.925) for researcher B. The best cut-off point for CPAx-Chi for the diagnosis of ICU-AW was 31.5. The sensitivity was 87% and specificity was 77% for researcher A, whereas it was 0.621, 31.5, 75% and 87% for researcher B, respectively. The consistency was high when taking CPAx-Chi ≤31 and MRC-Score ≤48 as the cut-off points for the diagnosis of ICU-AW. Cohen’s kappa=0.845 (p=0.02) in researcher A and 0.839 (p=0.04) for researcher B.ConclusionsCPAx-Chi demonstrated content validity, criterion-related validity and reliability. CPAx-Chi showed the best accuracy in assessment of patients at risk of ICU-AW with good sensitivity and specificity at a recommended cut-off of 31.

Intersectional research on childhood suicidality requires studies with a reliable and valid measure of suicidality, as well as a large sample size that shows some variability of suicidality across sex by race intersectional groups. Objectives: We aimed to investigate the feasibility of intersectionality research on childhood suicidality in the Adolescent Brain Cognitive Development (ABCD) study. We specifically explored the reliability and validity of the measure, sample size, and variability of suicidality across sex by race intersectional groups. Methods: We used cross-sectional data (wave 1) from the ABCD study, which sampled 9013 non-Hispanic white (NHW) or non-Hispanic black (NHB) children between the ages of 9 and 10 between years 2016 and 2018. Four intersectional groups were built based on race and sex: NHW males (n = 3554), NHW females (n = 3158), NHB males (n = 1164), and NHB females (n = 1137). Outcome measure was the count of suicidality symptoms, reflecting all positive history and symptoms of suicidal ideas, plans, and attempts. To validate our measure, we tested the correlation between our suicidality measure and depression and Child Behavior Checklist (CBCL) sub-scores. Cronbach alpha was calculated for reliability across each intersectional group. We also compared groups for suicidality. Results: We observed some suicidality history in observed 3.2% (n = 101) of NHW females, 4.9% (n = 175) of NHW males, 5.4% (n = 61) of NHB females, and 5.8% (n = 68) of NHB males. Our measure’s reliability was acceptable in all race by sex groups (Cronbach alpha higher than .70+ in all intersectional groups). Our measure was valid in all intersectional groups, documented by a positive correlation with depression and CBCL sub-scores. We could successfully model suicidality across sex by race groups, using multivariable models. Conclusion: Given the high sample size, reliability, and validity of the suicidality measure, variability of suicidality, it is feasible to investigate correlates of suicidality across race by sex intersections in the ABCD study. We also found evidence of higher suicidality in NHB than NHW children in the ABCD study. The ABCD rich data in domains of social context, self-report, schools, parenting, psychopathology, personality, and brain imaging provides a unique opportunity to study intersectional differences in neural circuits associated with youth suicidality.
