introduction: falling is a common problem after stroke that occurs following the physical and psychological problems. psychological factors such as reduce of self-efficacy in maintain balance could have an equal or even greater contribution than physical problems in falling. therefore, having a suitable tool with acceptable repeatability seems to be necessary for evaluation of individual confid...

OBJECTIVES To compare the reliability, validity, and responsiveness of the motor subscale of the functional independence measure (FIM), the original 10 item Barthel index (BI), and the 5 item short form BI (BI-5) in inpatients with stroke receiving rehabilitation. METHODS 118 inpatients with stroke at a rehabilitation unit participated in the study. The patients were tested with the FIM motor...

Background: Alcohol consumption is one of the main health problems in most countries. The purpose of the present study is to evaluate the reliability and validity of Alcohol Use Disorders Identification Test (AUDIT). Methods: By employing the method of available sampling, 70 alcoholic patients were included as case group and 70 normal age, gender and education matched individuals were also inc...

OBJECTIVE To evaluate reliability and construct validity of the Norwegian versions of the Roland Morris Disability Questionnaire and the modified Oswestry Disability Index. DESIGN Translation of two functional status questionnaires and a cross-sectional study of measurement properties. METHODS The questionnaires were translated and back-translated following the Guillemin criteria. The Norwe...

[Purpose] This study aimed to examine the inter- and intra-rater reliability and validity of the modified functional ambulation category (mFAC) scale. [Subjects and Methods] The participants were 66 stroke patients with hemiparalysis. The inter- and intra-rater validity of the mFAC was calculated using the Spearman correlation coefficient. A score comparison of the stable or maximum gait speed ...

INTRODUCTION This study assessed the validity and reliability of the Turkish version of the DSM-5 Posttraumatic Stress Symptom Severity Scale-Child Form for use among the Turkish population. METHODS The study group consisted of 30 patients that had been treated in a child psychiatry unit and diagnosed with posttraumatic stress disorder and 83 healthy volunteers that were attending middle or h...

INTRODUCTION The aim of this study was to adapt the Markova and Berrios Insight scale in Spanish and to analyze its psychometric properties and relationships to the severity of the psychotic symptoms. METHODOLOGY A translation-backtranslation of the original scale was elaborated and a panel of professionals participated to assess conceptual equivalence and naturality. This is a 30-item self-a...

This paper is concerned with feature screening and variable selection for varying coefficient models with ultrahigh dimensional covariates. We propose a new feature screening procedure for these models based on conditional correlation coefficient. We systematically study the theoretical properties of the proposed procedure, and establish their sure screening property and the ranking consistency...

The consistency of the quasi maximum likelihood estimator for random coefficient autoregressive models requires that the coefficient be a non-degenerate random variable. In this paper we propose empirical likelihood methods based on weighted score equations to construct a confidence interval for the coefficient. We do not need to distinguish whether the coefficient is random or deterministic an...
