BACKGROUND AND PURPOSE The aim of this study was to determine the face and criterion validity, stability reliability, and internal consistency of the Persian version of the Impact on Participation and Autonomy (IPA-p) scale among Iranian people with multiple sclerosis (MS). METHODS Trained experts interviewed 364 MS patients and their relatives to assess the criterion validity, stability reli...

BACKGROUND The General Practitioner Experiences Questionnaire (GPEQ) measures community mental health centres from the perspective of GP but lacked accessibility scales and documentation of centre level reliability. OBJECTIVES To assess the psychometric properties of the GPEQ following the inclusion of four new accessibility items and estimate centre level reliability for all scales and items...

background : the aim of training midwifery student is to increasing scientific and practical abilities in trainees in order to present caring health services and so the evaluation tools of these abilities has a great importance. for evaluating considered tools and for the reason of midwifery theoretical special courses importance this study tries to evaluate content validity, criterion validity...

Abstract Introduction. Agility is an important physical quality required in team sports including volleyball. The aims of this study were to quantify the reliability two reactive agility drills: (a) arrow test (ARAT) and (b) square upper body (SUBRAT). Their relationship was assessed with T-Test, lower limbs’ power evaluated using sprint vertical jump performance, while maximal strength back sq...

Original scientific paper After large scale blackout, there may be more than one black-start unit in power system. A rational subsystem partitioning restoration scheme could speed up the entire system restoration procedure and promote restoration reliability. In the paper, a subsystem partitioning strategy considering the restoration reliability is proposed. The calculation of nodes restoration...

-One critical issue for routing in mobile ad hoc networks (MANET) is how to select a reliable path that can last longer since mobility may cause radio links to break frequently. To answer this question, a criterion that can judge path reliability is needed. The reliability of a path depends on the availability of the links1 constituting the path. However, how to measure link availability to ans...

Software reliability models play a dominant role in the analysis of failure data for real time command and control software systems. Goel and Okumoto model is a non homogenous Poisson Process software reliability growth model which has gained a lot of importance in software reliability analysis and prediction. The process of parameter estimation is the major drawback of this model because the i...

This paper proposes a measurable criterion called “stitching reliability ’’ which reflects the stitching quality of panoramic mosaics. We also show that the accurate focal length from image sequences closely relates to the stitching reliability. However, current methods to recover the focal length are not very robust because mis-stitched areas in general panoramas are used in the computation of...

BACKGROUND The study aims to validate a previously developed and published combined success criterion for patients after multimodal pain therapy (Donath et al., BMC Health Serv Res 15:272, 2015). The criterion classifies treated patients as successful in the long term on the basis of pain severity, disability through pain, depressiveness, and health-related quality of life. METHODS Routine lo...

This study examined the factor structure, reliability, and validity of the Antisocial Process Screening Device-Self-Report (APSD-SR), the Youth Psychopathic Traits Inventory (YPI), and the YPI-Short Version (YPI-SV) in detained female adolescents aged 12 to 17 years. The proposed three-factor structure of the YPI and YPI-SV was replicated, whereas the proposed three-factor structure of the APSD...
