Reliability of knee extensor neuromuscular structure and function and functional tests’ performance

IntroductionThe aim of this study was to evaluate the intra and inter-rater and inter-analyzer reliability of neuromuscular variables and functional tests.MethodsCross-sectional crossover design. Two independent raters and analyzers evaluated twenty-two healthy subjects. Knee-extensor strength was assessed from three maximal voluntary isometric contractions. Muscle activation was obtained from the vastus lateralis (VL), rectus femoris (RF), and vastus medialis (VM) muscles. VL and RF muscles’ architecture [fascicle length (FL), pennation angle (PA), muscle thickness (MT)] was obtained at rest by ultrasound. The time from five sit-to-stand (STS) trials, and the distance from the 6-min walk test (6MWT) were obtained. Intraclass correlation coefficient was determined and classified as strong (r = 0.75–1.00), moderate (r = 0.40–0.74), and weak (r < 0.40).ResultsStrong intra-rater reliability values were observed for strength (r = 0.97), muscle activation [VL (r = 0.91); RF (r = 0.92); VM (r = 0.80)], VL [FL (r = 0.90); PA (r = 0.94); MT (r = 0.99)] and RF [MT (r = 0.85)] muscle architecture, STS (r = 0.95), and 6MWT (r = 0.98). Inter-rater reliability also presented strong values for strength (r = 0.97), muscle activation [VL (r = 0.94); RF (r = 0.79); VM (r = 0.78)], muscle architecture VL [PA (r = 0.81) and MT (r = 0.88)] and RF [MT (r = 0.80)], STS (r = 0.93), and 6MWT (r = 0.98). A moderate correlation VL muscle architecture [FL (r = 0.69)]. Inter-analyzer muscle architecture reliability presented strong VL [FL (r = 0.77); PA (r = 0.76); MT (r = 0.91)] and RF [MT (r = 0.99)].ConclusionThe high intra and inter-rater and inter-analyzer reliability values for most variables is evidence that they can be used for clinical evaluation. Muscle architecture might need a longer training period by different raters and analyzers to increase reliability.     

Reliability of forearm medial-anterior surface dimensional changes at different isometric hand grip forces

Indirect techniques of predicting hand grip force are fundamental to develop hand control systems for assistive devices. The purpose of this study was to determine the reliability of 3D position of forearm surface at different isometric hand grip forces. Three-dimensional motion analysis was used to measure displacement of 24 discrete and standardized surface markers placed on forearm in 20 healthy participants. The relative displacements were measured for isometric grip forces at 0%, 5%, 20% 50% and 80% of maximum voluntary contraction (MVC). Intraclass correlation coefficient (ICC) for relative radial displacement (RRD) of each marker was calculated. Averaged single measure ICC of 24 markers at five grip forces was 0.61; while the highest averaged single measure ICC (0.80) for all markers was achieved at 80% of MVC and the lowest (0.47) at 0% of MVC. The average measure ICC for each grip force across the 24 markers also increased with grip force from 0.80 at 0% of MVC to the maximum of 0.95 at 80% of MVC. In conclusion, RRD showed moderate and high ICCs for single and average measures respectively. Overall, this study suggests that the reliable dimensional changes of 3D positions of forearm surface might be considered as an indirect and non-invasive method to predict hand grip force in future.     

Psychometric Properties of the Self-Report Version of the Strengths and Difficulties Questionnaire in Korea

Objective

To examine the reliability and validity of the self-report Korean version of Strengths and Difficulties Questionnaire (SDQ-Kr) in the community sample.

Methods

The SDQ-Kr was administered to a large sample of school children and adolescents (n=2814) and youth attendees of a psychiatric clinic (n=385) aged 11-16 years. To examine temporal stability, the same questionnaire was administered to a subsample of 167 school youths five to six weeks after the initial assessment. To examine the reliability, we calculated Cronbach''s alpha coefficients for internal consistency and Pearson''s correlations for test-retest stability. In order to evaluate the factorial structure of the SDQ-Kr items, we conducted an exploratory factor analysis (EFA) with varimax rotation. Finally, discriminant validity was examined by using receiver operating characteristic (ROC) curves employing the area under the curve (AUC) as an index of discriminant ability.

Results

Although the internal consistency of some subscales of the SDQ-Kr was somewhat less satisfactory (alpha coefficients; 0.28-0.54) than the English original, coefficients for the total difficulties scores approached sufficient levels (coefficients; 0.69). Other psychometric properties including discriminant validity (AUC for total difficulties and four subscales >0.7) were comparable to those obtained in other language studies.

Conclusion

The self-report SDQ-Kr exhibited a low level of reliability, indicating that some items need to be further evaluated and revised to improve the psychometric properties. We suggest that the total difficulties score could be used with more confidence for screening possible mental health problems in youths.     

The Australian/Canadian Osteoarthritis Hand Index in a community‐dwelling population of older adults: Reliability and validity

Objective

To assess the acceptability and measurement properties of the Australian/Canadian Osteoarthritis Hand Index (AUSCAN) applied to a community‐dwelling population of older adults with hand problems.

Methods

Data were obtained from 2 related sources: 2,113 responders to a 2‐stage cross‐sectional postal survey who reported hand problems in the previous 12‐months, and 55 participants with hand problems completing a clinical assessment. The AUSCAN subscales were assessed for data quality and scaling properties. Test–retest reliability was assessed in clinical participants reporting no change in their hand condition at 1 month. Construct and criterion validity were evaluated using other data from the survey and clinical assessment. Internal consistency of the subscales was tested using Cronbach's alpha and item‐total correlations.

Results

AUSCAN subscales had high completion rates in the survey (missing data: 2.3–2.7%). Subscale scores covered the possible range but were skewed towards lower pain, stiffness, and functional problems. Test–retest reliability estimates supported the use of the pain and stiffness subscales (ρ > 0.7), with the estimate for stiffness being slightly lower (ρ = 0.64). The subscales demonstrated both construct validity (significantly higher subscale scores in participants reporting a recent general practitioner consultation for their hand problems and high correlations with hand function performance measures) and criterion validity (high correlations with generic health measures and disease‐specific measures).

Conclusion

The AUSCAN is a valid and reliable measure of hand problems in a community‐dwelling population of older adults. The AUSCAN performs well both in terms of its internal reliability and its relationship with external constructs.     

Does clinical experience affect the reproducibility of cervical vertebrae maturation method?

Objective:To assess interobserver and intraobserver reproducibility of the cervical vertebrae maturation method (CVMM) among three panels of judges with different levels of orthodontic experience (OE).Materials and Methods:Fifty individual lateral cephalograms of good quality with complete visualization of cervical vertebrae 1 to 4 were selected. Thirty clinicians, divided according to their OE into three groups (junior group, JU, OE ≤ 1 year; postgraduate group, PG, 2 ≤ OE ≤ 4 years; specialist group, SP, OE ≥ 7 years), evaluated the cephalograms in two sessions (T₁ and T₂) at 3 weeks apart. Kendall''s W and weighted Cohen''s kappa (κ) coefficients were performed to assess interobserver and intraobserver agreement. The level of significance was set as P < .05. For both the interobserver and the intraobserver datasets, the percentage of perfect agreement (PPA) and the number of stages apart for each disagreement were calculated.Results:Kendall''s W at T₁ was SP  =  0.61, PG  =  0.70, and JU  =  0.87; at T₂ it was SP  =  0.78, PG  =  0.85, and JU  =  0.86. The percentage of total interobserver perfect agreement (Inter-PPA) was 42.3% at T₁ and 46.3% at T₂. The JU group had the highest Cohen''s κ coefficient at 0.78, while the PG and SP had coefficients of 0.64 each. The percentage of total intraobserver perfect agreement (Intra-PPA) was 54.2%.Conclusions:The reproducibility of the method was not improved by the level of orthodontic experience. The group with the lowest level of orthodontic experience had the best performance.     

Validity of Chinese Version of the Composite International Diagnostic Interview-3.0 in Psychiatric Settings

Background:

The Composite International Diagnostic Interview-3.0 (CIDI-3.0) is a fully structured lay-administered diagnostic interview for the assessment of mental disorders according to ICD-10 and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. The aim of the study was to investigate the concurrent validity of the Chinese CIDI in diagnosing mental disorders in psychiatric settings.

Methods:

We recruited 208 participants, of whom 148 were patients from two psychiatric hospitals and 60 healthy people from communities. These participants were administered with CIDI by six trained lay interviewers and the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I, gold standard) by two psychiatrists. Agreement between CIDI and SCID-I was assessed with sensitivity, specificity, positive predictive value and negative predictive value. Individual-level CIDI-SCID diagnostic concordance was evaluated using the area under the receiver operator characteristic curve and Cohen''s K.

Results:

Substantial to excellent CIDI to SCID concordance was found for any substance use disorder (area under the receiver operator characteristic curve [AUC] = 0.926), any anxiety disorder (AUC = 0.807) and any mood disorder (AUC = 0.806). The concordance between the CIDI and the SCID for psychotic and eating disorders is moderate. However, for individual mental disorders, the CIDI-SCID concordance for bipolar disorders (AUC = 0.55) and anorexia nervosa (AUC = 0.50) was insufficient.

Conclusions:

Overall, the Chinese version of CIDI-3.0 has acceptable validity in diagnosing the substance use disorder, anxiety disorder and mood disorder among Chinese adult population. However, we should be cautious when using it for bipolar disorders and anorexia nervosa.
