Reliability, concurrent validity, and clinical feasibility of measurement methods determining volume in patients with lower limb lymphedema and healthy controls.

PURPOSE: To investigate reliability, concurrent validity, and clinical feasibility of measurements assessing volume in patients with lower limb lymphedema (LLL) and healthy controls. MATERIALS AND METHODS: To investigate intra- and interrater reliability, 47 patients with LLL and 30 healthy controls were assessed three times by two assessors. To investigate between session reliability, 50 participants were reassessed two weeks later. Each assessment included measurements of the midline region (hip circumference; suprapubic volume), leg volume (perimeter every 4 cm; Perometer®), and foot volume (water displacement; figure-of-eight method). Concurrent validity was assessed with correlation coefficients. Measurements were timed and practical limitations were reviewed. Clinical trial registration number: NCT: 05269264. RESULTS: Measurements of the total volume of different regions showed weak to very high intraclass correlation coefficients (ICCs) (0.131-998). Absolute and relative volume differences had lower ICC values (0.360-0.976). A strong correlation was found between the total volumes of the same region. The Perometer® and figure-of-eight method were the fastest method for leg and foot volume, respectively. CONCLUSIONS: The assessed total volumes might be more valuable in assessing the evolution of volume in bilateral LLL than the calculated absolute and relative differences between both limbs. The Perometer® and figure-of-eight method were the most time efficient for leg and foot volume, respectively.Implications for rehabilitationLymphedema is a chronic condition for which a reliable and clinically feasible assessment of volume is essential for the diagnosis, treatment decisions, and the evaluation of the treatment.This study shows that the total leg/foot volumes were more reliable than the calculated absolute and relative differences between both limbs and could therefore more valuable to evaluate bilateral lower limb lymphedema.For the assessment of leg volume, the Perometer® was the most reliable and fastest method.For the evaluation of the foot volume, the figure-of-eight method was overall the best method.

Teacher-assigned grades and external exams: sources of discrepancy.

Modest correlations between teacher-assigned grades and external assessments of academic achievement (r = .40-.60) have led many educational stakeholders to deem grades subjective and unreliable. However, theoretical and methodological challenges, such as construct misalignment, data unavailability and sample unrepresentativeness, limit the generalisability of previous findings. We overcome these challenges by exploiting rich, population-wide data from the National Registries in Norway (n = 511,858), where state regulations require close construct alignment between grades and external exams. Correlations between lower-secondary education final grades and external exam results (r = .64-.86) suggest that grades are better measures of academic achievement than previously acknowledged. Dominance analyses and multivariate regression analyses indicate that external exam results are the best predictor of grades in the same subject. However, our results also indicate that state regulations and quality assurance systems cannot completely eradicate potential sources of discrepancy.

Concurrent validity of objective assessment by finger tracking for open surgical suturing training.

BACKGROUND: The aim of this study is to evaluate whether the parameters 'time' and 'distance', measured by SurgTrac, correlate with the assessment of the same skills by blinded experts. METHODS: Basic open suturing tasks were executed by medical students. SurgTrac software measured objective parameters by tracking fingers. The executed tasks were recorded by a tablet and additionally assessed by a blinded expert with a Competency Assessment Tool-form (CAT-form). A Pearson's correlation was used to investigate the correlation between the parameters and the outcomes of the expert assessment. RESULTS: A strong correlation between the measured parameters of SurgTrac and the expert-assessment was found for knot tying by hand (r â€‹= â€‹-0.703) and vertical mattress suture (r â€‹= â€‹-0.644) and a moderate correlation for transcutaneous suture (r â€‹= â€‹-0.555) and intracutaneous suture (r â€‹= â€‹-0.451). CONCLUSION: The use of finger tracking by SurgTrac showed a good concurrent validity for the basic open suturing tasks knot tying by hand, transcutaneous suture and vertical mattress suture.

ICD-11 and DSM-5-TR prolonged grief symptoms and quality of life: A criterion validity test.

OBJECTIVE: Two similar but distinct versions of prolonged grief disorder (PGD) have recently been included in the International Classification of Diseases eleventh edition (ICD-11) and the Diagnostic and Statistical Manual of Mental Disorders - fifth edition, Text-Revision (DSM-5-TR). This study provides a criterion validity test of both new criteria sets of PGD, by examining concurrent and longitudinal associations of ICD-11 and DSM-5-TR prolonged grief symptoms with quality of life (QOL). METHODS: Bereaved adults completed a survey assessing ICD-11 and DSM-5-TR prolonged grief symptoms, depressive symptoms, insomnia symptoms and QOL at baseline and 6-month follow-up. RESULTS: Both ICD-11 and DSM-5-TR prolonged grief symptoms related negatively to QOL concurrently, while controlling for insomnia and depressive symptoms. ICD-11 prolonged grief symptoms, but not DSM-5-TR prolonged grief symptoms, predicted QOL at 6-month follow-up, while controlling for baseline QOL and insomnia and depression symptoms. CONCLUSIONS: Results provide consistent evidence for the criterion validity of ICD-11 PGD, but mixed evidence for the criterion validity of DSM-5-TR PGD. Study results can help guide attempts to optimize and harmonize future PGD criteria.

Development and validation of a Context-sensitive Positive Health Questionnaire (CPHQ): A factor analysis and multivariate regression study.

BACKGROUND: The concept of Positive Health (PH) has gained increasing attention as a way of measuring individuals' ability to adapt in the face of contextual challenges. However, a suitable measurement instrument for PH that encompasses contextual factors has not yet been developed. This paper responds to this need by developing a Context-specific Positive Health (CPH) measurement instrument that aligns with the Capability Approach (CA). METHODS: The measurement instrument was developed and tested among a representative sample of 1002 Dutch internet survey panel members with diverse sociodemographic backgrounds. The instrument was developed in two stages: a preparation phase consisting of focus groups and expert consultations, and a validation among a representative panel of Dutch citizens. The goal of the preparation phase, was to pilot test and refine previously proposed Positive Health questionnaires into an initial version of the CPHQ. The validation phase aimed to examine the initial CPHQ's factorial validity using Factor Analysis, and its concurrent validity using Multivariate Regression Analysis. RESULTS: The developed questionnaire demonstrated adequate factorial and concurrent validity. Furthermore, it explicitly includes an assessment of resilience, this being a key component of PH. CONCLUSIONS: The introduced measurement tool, the CPHQ, comprises 11 dimensions that we have labeled as follows: relaxation, autonomy, fitness, perceived environmental safety, exclusion, social support, financial resources, political representation, health literacy, resilience, and enjoyment. In this article, we present four major contributions. Firstly, we embedded the measurement in a theoretical framework. Secondly, we focused the questionnaire on a key concept of Positive Health - the "ability to adapt." Thirdly, we addressed issues of health inequality by considering contextual factors. Finally, we facilitated the development of more understandable measurement items.

Determining the MMPI-3 SUI scale's cross-sectional and prospective utility in suicide risk assessment.

OBJECTIVE: In-depth suicide risk assessments are particularly important to long-term suicide prevention. Broadband measures of psychopathology, such as the Minnesota Multiphasic Personality Inventory (MMPI) instruments, assess suicide risk factors and various mental health comorbidities. With the recent release of the MMPI-3, the Suicidal/Death Ideation (SUI) scale underwent revisions to improve its construct validity and detection of suicide risk factors. Thus, we hypothesized the MMPI-3 SUI scale would demonstrate medium to large associations with suicidal experience and behaviors, future ideation, and interpersonal risk factors of suicide. METHODS: A sample of 124 college students screened for elevated depressive symptoms completed a brief longitudinal study. Participants completed a baseline session including the MMPI-3 and criterion measures and three brief follow-ups every 2 weeks. RESULTS: SUI scores were most robustly associated with increased risk for past suicidal ideation, planning, and perceived burdensomeness. Prospectively assessed suicidal ideation was also meaningfully associated with SUI. SUI scale elevations indicate an increased risk of suicide-related risk factors. CONCLUSION: The MMPI-3 is a valuable tool to inform long-term suicide prevention for those experiencing elevated depressive symptoms as the SUI scale can assess past, current, and future suicide-related risk factors, including suicidal ideation and behaviors.

Oblique, forward, and lateral directions reach test distances in young adults, and concurrent validity of these tests with the center of pressure excursion in assessing the limits of stability.

Limits of stability is required to perform functional activities and other advanced tasks of life without losing balance, and assessment of limits of stability is essential in clinical practice. Forward, Lateral, and Oblique direction reach tests are clinical balance tests that assess limits of stability, and these reach distances in various directions may be symmetrical or asymmetrical. The aim was to establish the symmetry between various reach distances on three reach tests and to establish the concurrent validity of oblique, forward, and lateral direction reach test distances with limits of stability measured by the Iso Free machine of TecnoBody company. METHODS: The measurements of oblique, forward, and lateral reach tests and limits of stability excursions of center of pressure were taken in eight directions on Iso Free machine of Techno Body in fifty typical college-going young adults who were recruited through convenience sampling. Pearson correlation test was used to find the relationship between forward, lateral, and oblique direction reaches and limits of stability in forward, lateral, and oblique directions. Regression analysis was used to find the factors influencing the forward, lateral, and oblique reach tests. RESULTS: The reach distances were symmetrical, and out of the three tests, the lateral and oblique direction reach tests have a moderate positive correlation with limits of stability test in lateral and oblique directions with an r-value of 0.569 (p < 0.001) and 0.50 (p < 0.001) respectively. A Significant standardized beta value of 0.49 (p < 0.05) for the oblique direction reach test with total stability limits. CONCLUSIONS: The oblique and lateral direction reach tests are correlated with their respective center of pressure excursion. However, the oblique direction reach test moderately correlated with the total limits of stability scores. Forward reach distances were more in number followed by oblique and lateral reach distances among young Saudi adults.

The Kessler Psychological Distress Scale in Australian adolescents: Analysis of the second Australian Child and Adolescent Survey of Mental Health and Wellbeing.

INTRODUCTION: The 10-item Kessler Psychological Distress Scale (K10) is used to screen adolescents for mental disorders in Australian clinical practice; however, there are no Australian adolescent normative data. METHODS: Data were drawn from a nationally representative sample (N = 2964) of Australian adolescents (11-17 years). This study had three aims: (1) to examine concurrent validity between the K10 and Strengths and Difficulties Questionnaire (SDQ) emotional symptoms subscale, (2) to establish normative Australian adolescent K10 data and (3) to determine optimal K10 cut-off scores for screening for major depressive disorder (MDD) via receiver operator characteristic curve analysis and stratum-specific likelihood ratios. RESULTS: The K10 and SDQ emotional symptoms scales were moderately correlated (rs = 0.63, p < 0.001). Older female adolescents reported higher total K10 scores compared with younger female adolescents (15-17 years: M = 20.2, standard error [SE] = 0.3; 11-14 years: M = 16.8, SE = 0.3) and male adolescents (11-14 years: M = 16.6, SE = 0.2; 15-17 years: M = 16.0, SE=0.2). K10 scores to optimally discriminate those with and without MDD varied by age and sex and had low specificities. Stratum-specific likelihood ratios indicated adolescents with a K10 score of ≥30 will have a 12.9 (95% confidence interval = [10.2, 16.2]) increased likelihood of MDD. CONCLUSION: The K10 has utility for assessing psychological distress in health care and epidemiological research in Australian adolescents. Adolescents with K10 scores in the 'very high' range are at increased risk of MDD. Further assessment of these young people is indicated to identify those with or at risk of developing MDD.

Patient-Reported Outcomes Measurement Information System Physical Function and Global Physical Health Subscale Strongly Correlate and Perform Similarly to the Knee Injury and Osteoarthritis Outcome Score-Physical Function Short Form.

BACKGROUND: Arthroplasty surgeons use a variety of patient-reported outcome measures (PROMs) to assess functional well-being, including the Knee Injury and Osteoarthritis Outcome Score (KOOS) Physical Function short form (KOOS-PS), Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function Short Form 10a (PROMIS PF SF 10a), and PROMIS Global-10 Physical Health subscale. However, there is a paucity of literature assessing their concurrent validity and performance. METHODS: Between June 2016 and December 2020, patient visits at an arthroplasty clinic for knee concerns were identified. Patients who completed KOOS-PS, PROMIS PF SF 10a, and PROMIS Global-10, including its physical and mental health subscales, at the same visit were identified. Spearman rho (ρ) correlations were calculated and ceiling and floor effects identified. Overall, 5,303 patient encounters were included. RESULTS: Among physical function domains, strong correlation existed between the KOOS-PS and PROMIS PF SF 10a (ρ = 0.76, P < .001), KOOS-PS and PROMIS Global Physical Health (ρ = 0.71, P < .001), and PROMIS PF SF 10a and PROMIS Global Physical Health (ρ = 0.78, P < .001). No physical function-focused PROM had an appreciable floor effect (ie, at or more than 1%). The KOOS-PS had a small but measurable ceiling effect (n = 105 [2.0%]). CONCLUSIONS: All of the examined PROMs are acceptable to measure the functional status of patients with knee pathology, with the PROMIS Global-10 also being able to capture elements of mental health too. The PROMIS Global-10 may be of most value of the PROMs assessed, as the United States Centers for Medicare and Medicaid Services already incorporate the mental health component into new alternative payment models.

Concurrent Validity and Test-Retest Reliability of the 3-Meter Backward Walk Test in Stroke Survivors.

In the context of evaluating physical function in individuals with stroke, the 3-Meter Backward Walk Test (3MBWT) emerges as a potential tool of interest. The purpose of this study was to assess the test-retest reliability and concurrent validity of the 3MBWT and its correlation with falling incidents. Conducted in a neurological rehabilitation center, 35 ambulatory individuals with stroke were enrolled within a month post-stroke onset. These participants, with a Functional Ambulation Category score of ≥4, underwent the 3MBWT, Functional Gait Assessment (FGA), 10-Meter Walk Test (10MWT), and 6-Minute Walk Test (6MWT) under the supervision of different physiotherapists. The results indicate that the 3MBWT demonstrated high reliability, with an Intraclass Correlation Coefficient of 0.97 (95% CI: 0.95, 0.98). It also showed significant concurrent validity with other established walking tests like the 6MWT (r = -0.78) and 10MWT (r = 0.71), with a moderate correlation with the FGA (r = -0.54). No marked differences in test outcomes were observed between participants based on their fall history. Conclusively, the 3MBWT proves to be highly reliable and agrees well with existing walking function assessments for stroke patients, suggesting its potential as a time-efficient alternative.

A Digital Box and Block Test for Hand Dexterity Measurement: Instrument Validation Study.

BACKGROUND: The Box and Block Test (BBT) measures unilateral gross manual dexterity and is widely used in clinical settings with a wide range of populations, including older people and clients with neurological disorders. OBJECTIVE: In this study, we present a newly developed digitized version of the BBT, called the digital BBT (dBBT). The physical design is similar to the original BBT, but the dBBT contains digital electronics that automate the test procedure, timing, and score measurement. The aim of this study is to investigate the validity and reliability of the dBBT. METHODS: We performed measurements at 2 time points for 29 healthy participants. BBT and dBBT were used at the first measurement time point, and dBBT was used again at the second measurement time point. Concurrent validity was assessed using the correlation between BBT and dBBT, the paired t test, and the Bland-Altman analysis. Test-retest reliability and interrater reliability were examined using the interclass correlation coefficient (ICC) by repeated measures with the dBBT within an interval of 10 days. RESULTS: Our results showed moderate concurrent validity (r=0.48, P=.008), moderate test-retest reliability (ICC 0.72, P<.001), a standard error of measurement of 3.1 blocks, and the smallest detectable change at a 95% CI of 8.5 blocks. Interrater reliability was moderate with an ICC of 0.67 (P=.02). The Bland-Altman analysis showed sufficient accuracy of the dBBT in comparison with the conventional BBT. CONCLUSIONS: The dBBT can contribute to objectifying the measurement of gross hand dexterity without losing its important characteristics and is simple to implement.

Test de Atención Infantil: análisis de las características psicométricas y valores de referencia preliminares / Test of Child Attention: Analysis of the Psychometric Characteristics and Preliminary Reference Values / Teste de Atenção Infantil: análise de características psicométricas e valores de referência preliminares

La atención es definida como un constructo multidimensional, encargado de regular sobre qué estímulos se dirigirán los recursos perceptivos, filtrando información irrelevante con el fin de favorecer la retención de información durante un período antes de actuar sobre ella. La evaluación computarizada de la atención ha ido cobrando relevancia tanto en la investigación como en las prácticas del quehacer profesional. Los objetivos de este estudio fueron: 1) analizar la consistencia interna y la validez concurrente del Test de Atención Infantil 6.0 (tai), versión computarizada; y 2) obtener los valores de referencia preliminares para cada subtest del tai. Los estudios de confiabilidad y validez del tai corresponden a una muestra de 122 escolares de Mendoza (Argentina). Al analizar la consistencia interna se obtuvieron valores satisfactorios para cada uno de los subtests (Test 1, kr 20 = 0.78; Test 2, kr 20 =0.74; Test 3, kr20 = 0.73). Se obtuvieron valores satisfactorios al explorar la estabilidad del instrumento. Al analizar la validez concurrente, los resultados indicaron correlaciones positivas moderadas y significativas (p <0.01) entre el test Caras-R y los subtests 1 y 2 del tai, utiliza-do para evaluar desempeño atencional. Se observaron asociaciones positivas significativas (p <0.01) entre el subtest 3 del tai y el Test de Bloques de Corsi, usado para evaluar memoria de trabajo visoespacial. Estos resultados señalan que el tai, instrumento desarrolla-do para evaluar la atención y memoria de trabajo visuoespacial en escolares, presenta indicadores adecuados de validez y confiabilidad. Se discuten los hallazgos, limitaciones y futuras líneas de investigación.

Attention has been defined as a multidimensional construct, dealing with regulation of which stimuli the perceptual resources are directed to, filtering irrelevant information out to favor the retention of relevant information for a period of time, before acting on it. The computerized evaluation of attention has been gaining relevance both in research and in professional practice. The objectives are: 1) to analyze internal consistency and concurrent validity of the Child Attention Test 6.0 (tai), computerized version 6.0; and, 2) to obtain the preliminary reference values for each of the tai subtests done. The data for the validity and reliability studies of the tai corresponds to a sample of 122 schoolchildren in Mendoza (Argentina). When analyzing the internal consistency, satisfactory values were obtained for each subtest (Test 1, kr 20 = 0.78; Test 2, kr 20 = 0.74; and Test 3, kr 20 = 0.73). Satisfactory values were obtained when exploring the stability of the instrument. For concurrent validity, the results indicate significant moderate positive correlations (p <0.01) between the scores obtained in the Caras-R test and subtests 1 and 2 of the tai, used to evaluate attentional performance. Significant positive associa-tions (p <0.01) were observed between tai subtest 3 and the Corsi Block Test, used to assess visuospatial working memory. These results indicate that the tai, an instrument developed in order to evaluate attention and visuospatial working memory of school children, presents adequate indicators of validity and reliability. The findings, limitations, and future lines of research are discussed

Evaluating and Comparing the Correlation and Performance of PROMIS and FAAM ADL in a Foot and Ankle Patient Population.

BACKGROUND: There is a paucity of literature assessing 2 of the commonly used static Patient-Reported Outcomes Measurement Information System (PROMIS) forms (PROMIS Global-10 and PROMIS Physical Function Short Form 10a [PF SF 10a]) and the Foot and Ankle Ability Measure Activities of Daily Living (FAAM ADL). METHODS: The PROMIS Global-10, PROMIS PF SF 10a, and FAAM ADL were compared among new foot and ankle patients. Spearman rho (ρ) correlations were calculated, and ceiling and floor effects were determined. RESULTS: The FAAM ADL demonstrated strong correlations with PROMIS PF SF 10a, P = .88, 95% confidence interval (CI): 0.86-0.90, P < .001, and PROMIS Global-10 Physical Health (P = .75, 95% CI: 0.71-0.78, p < .001). The FAAM ADL and PROMIS Global-10 Mental Health demonstrated a moderate correlation (P = .41, 95% CI: 0.34-0.47, P < .001). No PROM demonstrated an appreciable floor effect. The PROMIS Global-10 Physical Health demonstrated the lowest ceiling effect (n=11 [1.6%]). CONCLUSION: Because the PROMIS Global-10 captures physical health adequately, provides mental health insight, and performs as well (if not better), we recommend the PROMIS Global-10 among the PROMs studied.Level of Evidence: Level III.

Measuring Depression in Young Adults: Preliminary Development of an English Version of the Teate Depression Inventory.

Depression is a common and debilitating condition that impacts individuals with various cultural backgrounds, medical conditions, and life circumstances. Thus, assessment tools need to be useful among different cultural groups. The 21-item Teate Depression Inventory (TDI) was developed in Italy, is designed to assess major depression, and focuses on cognitive and affective rather than somatic symptoms. This study aims to examine the factor structure and concurrent validity of the TDI English version among a non-clinical population in the United States. Participants included 398 adults (mean age 19.89 years, SD = 2.72, range: 18 to 46 years old) who completed the TDI and The Center for Epidemiologic Studies Depression Scale-Revised (CESD-R). The results supported a three-factor bifactor structure of the TDI (Positive Affect, Negative Affect, and Daily Functioning), which largely corresponds to the Tripartite Model of affective disorders. These findings support the use of TDI scores as measures of depressive symptoms among U.S. young adults, offering researchers and practitioners a brief and useful tool.

The Validity of Hawkin Dynamics Wireless Dual Force Plates for Measuring Countermovement Jump and Drop Jump Variables.

Force plate testing is becoming more commonplace in sport due to the advent of commercially available, portable, and affordable force plate systems (i.e., hardware and software). Following the validation of the Hawkin Dynamics Inc. (HD) proprietary software in recent literature, the aim of this study was to determine the concurrent validity of the HD wireless dual force plate hardware for assessing vertical jumps. During a single testing session, the HD force plates were placed directly atop two adjacent Advanced Mechanical Technology Inc. in-ground force plates (the "gold standard") to simultaneously collect vertical ground reaction forces produced by 20 participants (27 ± 6 years, 85 ± 14 kg, 176.5 ± 9.23 cm) during the countermovement jump (CMJ) and drop jump (DJ) tests (1000 Hz). Agreement between force plate systems was determined via ordinary least products regression using bootstrapped 95% confidence intervals. No bias was present between the two force plate systems for any of the CMJ and DJ variables, except DJ peak braking force (proportional bias) and DJ peak braking power (fixed and proportional bias). The HD system may be considered a valid alternative to the industry gold standard for assessing vertical jumps because fixed or proportional bias was identified for none of the CMJ variables (n = 17) and only 2 out of 18 DJ variables.

Construct validity of the General Health Questionnaire (GHQ-12) in patients with COVID-19 and its demographic and medical correlates.

Introduction: The present cross sectional study aimed to evaluate the construct and criterion validity, reliability, and gender and age differences of the 12-item General Health Questionnaire (GHQ-12) among hospitalized patients with COVID-19 in 2020. The criterion validity was assessed via its link with perceived stress, sleep quality, daily life activities, and demographic and medical characteristics. Methods: A total of 328 COVID-19 patients (55.8% men; Mage = 50.49, SD = 14.96) completed the GHQ-12, the Perceived Stress Scale (PSS), the Pittsburgh Sleep Quality Index (PSQI), the Activities of Daily Life (ADL)-Katz Scale, and the Lawton Instrumental Activities of Daily Living Scale (IADL). Results: Among 13 factorial models, the three-factor model (successful coping, self-esteem, and stress) was shown to have the best fit. GHQ-12 was positively associated with PSQI, PSS, Hyperlipidemia, psychiatry disorders, hospitalization duration, the change in sleep time, and use of sleeping pills, and negatively correlated with educational level, and the number of family members. The GHQ-12 also had a negative correlation with ADL and IADL in over 60 years of age group. Females scored higher on total GHQ-12 scores, compared to males. Finally, the hospitalization duration was longer for patients over 60 (mean = 8.8 days, SD = 5.9) than patients under 60 (mean = 6.35 days, SD = 5.87). Discussion: Overall, the findings provided evidence that mental distress in patients with COVID-19 is correlated with high perceived stress, low sleep quality, low ADL and IADL, and a range of demographic features and medical conditions. Designing psychological interventions for these patients that target the aforementioned correlates of mental distress is warranted.

Implementation of a Canine Ergonomic Abdominal Simulator for Training Basic Laparoscopic Skills in Veterinarians.

The validity of the CALMA Veterinary Lap-trainer simulator (CVLTS) for training basic veterinary laparoscopic skills was assessed and compared to a simple collapsible mobile box trainer. Ten veterinarian surgeons with no experience in laparoscopic surgery and four experts with at least two years of experience in minimally invasive surgery (MIS) were included. The training curriculum included object transfer, non-woven gauze cutting with curved scissors, and interrupted and continuous intracorporeal sutures, which were practiced on the CVLTS. The initial and final assessments were carried out in both the CVLTS and in a collapsible mobile simulator. These were video-recorded and evaluated by external experts using the Objective Structured Assessment of Technical Skills (OSATS) and a specific scale evaluation in a double-blinded schedule. The time, angular displacement, number, and movement smoothness were recorded using a hands movement assessment system (HMAS). Through a survey, the face validity and content were evaluated. The data were analyzed by a Pearson's proportions comparison or Mann Whitney U test and a bilateral Student's t-test. The experimental group OSATS, specific scores, and HMAS values, with the exception of the smoothness of movements, significantly improved after training, with no statistically significant differences compared to the expert group. No differences were found between the two simulators. The experts' and experimental participants' CVLTS mean score was 4.8. Our data support the CVLTS validations for laparoscopic surgery basic skills training.

Measures of Maximal Tactile Pressures during a Sustained Grasp Task Using a TactArray Device Have Satisfactory Reliability and Concurrent Validity in People with Stroke.

Sensor-based devices can record pressure or force over time during grasping and therefore offer a more comprehensive approach to quantifying grip strength during sustained contractions. The objectives of this study were to investigate the reliability and concurrent validity of measures of maximal tactile pressures and forces during a sustained grasp task using a TactArray device in people with stroke. Participants with stroke (n = 11) performed three trials of sustained maximal grasp over 8 s. Both hands were tested in within- and between-day sessions, with and without vision. Measures of maximal tactile pressures and forces were measured for the complete (8 s) grasp duration and plateau phase (5 s). Tactile measures are reported using the highest value among three trials, the mean of two trials, and the mean of three trials. Reliability was determined using changes in mean, coefficients of variation, and intraclass correlation coefficients (ICCs). Pearson correlation coefficients were used to evaluate concurrent validity. This study found that measures of reliability assessed by changes in means were good, coefficients of variation were good to acceptable, and ICCs were very good for maximal tactile pressures using the average pressure of the mean of three trials over 8 s in the affected hand with and without vision for within-day sessions and without vision for between-day sessions. In the less affected hand, changes in mean were very good, coefficients of variations were acceptable, and ICCs were good to very good for maximal tactile pressures using the average pressure of the mean of three trials over 8 s and 5 s, respectively, in between-day sessions with and without vision. Maximal tactile pressures had moderate correlations with grip strength. The TactArray device demonstrates satisfactory reliability and concurrent validity for measures of maximal tactile pressures in people with stroke.

Examining concurrent validity and item selection of the Session Wants and Needs Outcome Measure (SWAN-OM) in a children and young people web-based therapy service.

Background: Single-session mental health interventions are frequently attended by children and young people (CYP) in both web-based and face-to-face therapy settings. The Session "Wants" and "Needs" Outcome Measure (SWAN-OM) is an instrument developed in a web-based therapy service to overcome the challenges of collecting outcomes and experiences of single-session therapies (SSTs). It provides pre-defined goals for the session, selected by the young person prior to the intervention, on which progress toward achievement is scored at the end of the session. Objective: The objective of this study was to evaluate the instrument's psychometric properties, including concurrent validity against three other frequently used outcome and experience measures, at a web-based and text-based mental health service. Methods: The SWAN-OM was administered for a period of 6 months to 1,401 CYP (aged 10-32 years; 79.3% white; 77.59% female) accessing SST on a web-based service. Item correlations with comparator measures and hierarchical logistic regressions to predict item selection were calculated for concurrent validity and psychometric exploration. Results: The most frequently selected items were "Feel better" (N = 431; 11.61%) and "Find ways I can help myself" (N = 411; 11.07%); unpopular items were "Feel safe in my relationships" (N = 53; 1.43%) and "Learn the steps to achieve something I want" (N = 58; 1.56%). The SWAN-OM was significantly correlated with the Experience of Service Questionnaire, particularly the item "Feel better" [rs(109) = 0.48, p < 0.001], the Youth Counseling Impact Scale, particularly the item "Learn the steps to achieve something I want" [rs(22) = 0.76, p < 0.001], and the Positive and Negative Affect Schedule, particularly the items "Learn how to feel better" [rs(22) = 0.72, p < 0.001] and "Explore how I feel" [rs(70) = -0.44, p < 0.001]. Conclusion: The SWAN-OM demonstrates good concurrent validity with common measures of outcome and experience. Analysis suggests that lesser-endorsed items may be removed in future iterations of the measure to improve functionality. Future research is required to explore SWAN-OM's potential to measure meaningful change in a range of therapeutic settings.
