The Reliability and Validity of the Group Participation Scale

Abstract: a single operationally defined dimension of &dquo;effectiveness in group participation.&dquo; To them, effective group participation involved behavior which would initiate, sustain, define, and direct activity toward goals which were held by the group. Their Group Participation Scale is composed of 24 behavior description items, such as &dquo;V6’ho never does anything?,&dquo; &dquo;Who is a good follower in the group?,&dquo; &dquo;Who pushes new ways of doing things?,&dquo; etc. Each of these 24 items has a weight ranging from one (least effective participation) to eight (most effective participation), which was determined by judges using Thur-

Study of non-probabilistic reliability measures of structures based on interval

Abstract: In the case of scarce data or insufficient information available,a non-probabilistic set model is valid alternative to structural reliability analysis.The non-probabilistic reliability measures based on interval and their interrelations are investigated.Three kinds of non-probabilistic reliability measures based on interval,which are reliability index,set based reliability measure and safety possibility degree are compared.The non-probability set-based reliability nature and the computational method have been studied.In the stress-strength interference case,the non-probability set-based of reliability analytic method is suggested to be applied to carry on the structural reliability analysis,then several common non-probability set-based of reliability computational method for stress-strength combination are also proposed.At last,the conclusion is verified by an example.

Investigating the reliability of contemporary Chinese pulse diagnosis as a diagnostic tool in Oriental medicine

Abstract: Introduction: Few studies have evaluated the reliability of pulse diagnosis clinically despite it being a fundamental part of Oriental medicine diagnostics. The objective of this study was to determine the levels of intra-rater and inter-rater reliability of practitioners using an operationally defined method, Contemporary Chinese Pulse Diagnosis™ (CCPD), to evaluate the radial pulse of volunteer subjects. Methods: The study utilised a real-life design to investigate CCPD in a clincal setting. Fifteen volunteer subjects and six testers skilled in the CCPD method were recruited. Two episodes of data collection were conducted 28 days apart as a practical test and retest. For each subject, four pulse rates and 30 pulse categories defined nby the CCPD system were assessed and reassessed by the same four testers during both phases of testing. All assessments were conducted according to the CCPD method. Intra rater reliability was measured by comparing individual tester results on day one with day two, while inter rater agreement and reliability were determined by comparing all testers across both days. Rates were analysed using ANOVA, while the remaining data employed Cohen's kappa coefficient. Kappa values were interpreted according to previous clinical studies and parameters considered acceptable when using a tool such as CCPD to assist in clinical diagnosis. Cross-referencing percentage agreement with the appropriate kappa results rated individual pulse quality dependability. Results: Of the 11760 kappa calculations excellent to good agreement (kappa =0.60) in 67% of intra rater and 44.1% of inter rater calculations indicated CCPD to be a reliable method of pulse diagnosis. Unacceptable agreement (kappa =0.40) in 14.3% of intra rater and 30.5% of inter rater calcualtions correlated most profoundly to CCPD pulse category/position and to several subjects. Reliability of individual pulse qualities depended on the location of the quality, the complexity of the sensation description and the classification of grouping to which the quality belonged. Conclusions: The results confirmed the findings of earlier studies that when the system of pulse diagnosis is operationally defined, acceptable levels of reliabilitycan be achieved. Additionally bilateral methods of palpation were identified as more reliable than those that assessed pulse positions using a single finger. Unacceptable reliability for the Combined Complementary Positions suggested imprecise descriptions, wording or language for accessing the Pleura, Esophagus and Diaphragm Positions may exist within the CCPD operational definitions. Further any uncertain terminology needs revision as the data indicated this might have contributed to variance within the testers' techniques. Also the pulse qualities Muffled, Change of Amplitude, Blood Heat, Blood Thick, and Flooding Deficient, while not shown to be unreliable, had comparatively lower reliability suggesting the definitions for these qualities may also need modification.

Goniometric evaluation of the spinal sagittal curves in children and adolescents: A reliability study

Abstract: BACKGROUND Gold standard for spine deformities assessment is X rays, but the procedure bears a risk of exposure. OBJECTIVE To investigate intra-rater and inter-rater reliability of a pocket compass needle goniometer (IncliMed®, University of Padua) to non-invasively evaluate spine curves in children and adolescents. METHODS Prospective reliability study in a paediatric population (mean age 12.5 years ± 2.5). Children with spine deformities (Scheuermann's or postural kyphosis, idiopathic scoliosis) and healthy controls were included. Two physician measured spinal curves with the surface goniometer IncliMed® within a temporal range of 10 minutes. Participants were re-tested after a mean of 28 days for the intra-rater study. Agreement limit and coefficient of repeatability were calculated according to the linear regression analysis; the Bland and Altman method was applied to obtain average of differences and standard error of the mean of the differences. RESULTS One hundred and thirty-nine subjects participated to the inter-rater reliability assessment; 30 to the intra-rater reliability assessment. Inter-observer variability for IncliMed® measurements was ± 11° both for kyphosis and for lordosis. The intra-observer variability for kyphosis and lordosis measurements was ± 11° and ± 12°. CONCLUSIONS IncliMed® is a reliable, non-invasive tool to screen and monitor spinal curves in paediatric populations.
