TL;DR: New reliability models are derived to describe how test-based software reliability estimates depend on the component structure of code, providing a meaning for ‘reliable software design,’ making it possible to identify software designs whose reliability can be demonstrated.
Abstract: New reliability models are derived to describe how test-based software reliability estimates depend on the component structure of code. The models can analyze dependent component failures. Models of this type are important for two main reasons. Firstly, they provide a quality model for software development based on component reuse. For simple software architectures, it is shown that it is feasible to re-use evidence of a component’s reliability from previous testing/usage in a different system. This technique has potential to provide extremely efficient software verification. Secondly, the new models provide a meaning for ‘reliable software design,’ making it possible to identify software designs whose reliability can be demonstrated. Traditionally, the complexity of a computation is measured in terms of the number of elemental computations used. In contrast, a statistical complexity measure is proposed to describe complexity in terms of statistical software testability. A highly complex program requires intense testing in order to justify a claim that the program achieves a given level of reliability. A low complexity program requires less testing to achieve the same claim.

TL;DR: To determine the inter‐rater, intrarater, and intrasubject reliability of the Hoffmann sign, a computer simulation is used to evaluate the ability of the sign to be translated into English.
Abstract: Objective To determine the inter-rater, intrarater, and intrasubject reliability of the Hoffmann sign. Design Observational, cross-sectional study. Setting Veterans Affairs medical center. Patients Fifty-two consenting subjects without amputation of the first through third fingers, fixed finger contractures, relapsing remitting multiple sclerosis, or any acute central neurological illness or injury within the past 3 months requiring hospital admission were recruited from inpatients and outpatients in the Spinal Cord Injury and Physical Medicine and Rehabilitation services. Interventions The Hoffmann sign was elicited by 1 primary and 3 secondary investigators who used a standardized technique. The Hoffmann sign was considered positive if any reflexive flexion of the distal phalanx of the thumb or any of the fingers was present. In the first session, the primary and one secondary examiner performed 2 trials on both hands of each subject. Each investigator pair repeated the procedure in a second session. Main Outcome Measures Cohen's κ coefficient was calculated to determine (1) inter-rater reliability, calculated per investigator pair per hand, for the first trial of a session; (2) intrarater reliability, calculated between the 2 trials of each session per investigator; and (3) intrasubject reliability, calculated per hand of each subject between the first trials of the 2 sessions. Results Inter-rater κ was 0.65 (188 pairs), intrarater κ was 0.89 (384 pairs), and intrasubject κ was 0.73 (178 pairs). All κ values were obtained with P Conclusions The Hoffmann sign has substantial inter-rater and intrasubject reliability, in addition to outstanding intrarater reliability, when tested with the use of a standardized technique.

TL;DR: Patients can acquire the necessary skills to conduct a correct joint assessment after initial and thorough training and patient-performed assessments of joints and DAS28-CRP in an eHealth home-monitoring solution were reliable and comparable with HCP.
Abstract: Objective. In an eHealth setting, to investigate intra- and interrater reliability and agreement of joint assessments and Disease Activity Score using C-reactive protein (DAS28-CRP) in patients with rheumatoid arthritis (RA) and test the effect of repeated joint assessment training. Methods. Patients with DAS28-CRP ≤ 5.1 were included in a prospective cohort study (clinicaltrials.gov: NCT02317939). Intrarater reliability and agreement of patient-performed joint counts were assessed through completion of 5 joint assessments over a 2-month period. All patients received training on joint assessment at baseline; only half of the patients received repeated training. A subset of patients was included in an appraisal of interrater reliability and agreement comparing joint assessments completed by patients, healthcare professionals (HCP), and ultrasonography. Cohen’s κ coefficients and intraclass correlation coefficients (ICC) were used for quantifying of reliability of joint assessments and DAS28-CRP. Agreement was assessed using Bland-Altman plots. Results. Intrarater reliability was excellent with ICC of 0.87 (95% CI 0.83–0.90) and minimal detectable change of 1.13. ICC for interrater reliability ranged between 0.69 and 0.90 (good to excellent). Patients tended to rate DAS28-CRP slightly higher than HCP. In patients receiving repeated training, a mean difference in DAS28-CRP of −0.08 was observed (limits of agreements of −1.06 and 0.90). After 2 months, reliability between patients and HCP was similar between groups receiving single or repeated training. Conclusion. Patient-performed assessments of joints and DAS28-CRP in an eHealth home-monitoring solution were reliable and comparable with HCP. Patients can acquire the necessary skills to conduct a correct joint assessment after initial and thorough training. [clinicaltrials.gov (NCT02317939)]
