To determine (i) the dimensional invariance of instrumental and basic activities of daily living (IADL/ADL) by gender subgroups, and (ii) the extent to which ADL dimensionality varies with the inclusion or exclusion of nondisabled people. Data were taken from the 1999 Spanish Survey on Disability, Impairment and State of Health. The analysis focussed on(More)
The Maudsley Obsessive-Compulsive Inventory (MOCI) is one of the most used tests in clinical psychology for assessing the obsessive and compulsive symptoms in psychiatric patients and as a screening tool in nonclinical population. A reliability generalization meta-analysis was carried out with the purpose of studying how test scores reliability varies along(More)
The Yale-Brown Obsessive-Compulsive Scale for children and adolescents (CY-BOCS) is a frequently applied test to assess obsessive-compulsive symptoms. We conducted a reliability generalization meta-analysis on the CY-BOCS to estimate the average reliability, search for reliability moderators, and propose a predictive model that researchers and clinicians(More)
BACKGROUND There is a growing interest in designing instruments to assess obsessive-compulsive symptoms in children. The Obsessive-Compulsive Inventory-Child Version (OCI-CV) has showed to be a valid in the evaluation of OCD in clinical and nonclinical populations. The main goal in this study was to analyze factor structure and psychometric properties of(More)
The purpose of this study was to analyze the component structure and reliability of the Liebowitz Social Anxiety Scale for Children and Adolescents, self-report version (LSAS-CA-SR), in a Spanish community population. The sample was made up of 422 students from elementary and high schools, aged between 10 and 17 years. Exploratory factor analysis isolated(More)
Reliability generalization is a meta-analytic approach to study how reliability estimates of a test scores depend on the specific characteristics under which the test is applied and, as a consequence, the risks of inducing score reliability from previous applications of the test. The Hamilton Rating Scale for Depression (HAMD) is one the most popular(More)
Precursors of the reliability generalization (RG) meta-analytic approach have not established a single preferred analytic method. By means of five real RG examples, we examine how using different statistical methods to integrate coefficients alpha can influence results in RG studies. Specifically, we compare thirteen different statistical models for(More)
INTRODUCTION One of the tests that is mostly widely used to evaluate aphasia in clinical practice is the Boston Naming Test (BNT), a classic test in which 60 black and white pictures are presented to subjects in order to evaluate their capacity to put a name to such pictures. Despite its psychometric goodness, the number of items in the test has to be(More)
The reliability generalization (RG) approach is a kind of meta-analysis that aims to statistically integrate a set of independent reliability coefficients obtained in several applications of a test, with the purpose of characterizing the measurement error and determining which factors related to the studies and samples can explain its variability. Diverse(More)
BACKGROUND Patients' opinions are crucial in assessing the effectiveness of the ethical theories which underlie the care relationship between patients and primary health care professionals. OBJECTIVES To study the ethical behaviour of primary health care professionals with respect to communication issues according to patients' opinions. METHODS(More)
