Brief cognitive assessment instruments in schizophrenia and bipolar patients, and healthy control subjects: A comparison study between the Brief Cogn…
2011
Cognitive impairment in schizophrenia and psychosis is ubiquitous and acknowledged as a core feature of clinical expression, pathophysiology, and prediction of functioning. However, assessment of cognitive functioning is excessively time-consuming in routine practice, and brief cognitive instruments specific to psychosis would be of value. Two screening tools have recently been created to address this issue, i.e., the Brief Cognitive Assessment Tool for Schizophrenia (B-CATS) and the Screen for Cognitive Impairment in Psychiatry (SCIP). The aim of this research was to examine the comparative validity of these two brief instruments in relation to a global cognitive score. 161 patients with p…
Dimensionality of depression in acute schizophrenia: a methodological study using the Bech-Rafaelsen Melancholia Scale (BRMES).
1998
Abstract Despite the great clinical importance of depressive symptoms in schizophrenia there is a lack of studies on the assessment and evaluation of depression in acutely psychotic patients. For the Bech-Rafaelsen Melancholia Scale (BRMES), among other advantages, the concept of unidimensionality was confirmed in patients with major depression by different methodological approaches including Rasch analysis. The present evaluation was designed to investigate the scale properties of the BRMES in acutely schizophrenic patients with particular emphasis on the dimensionality of the scale. Three different statistical approaches were used: principal component analysis in combination with computer…
Performance of the compensation comparison method for retinal straylight measurement: effect of patient's age on repeatability
2008
Aim: The assessment of repeatability and reproducibility of retinal straylight measurements with the C-Quant straylight meter (Oculus AG, Germany) and the effect of patient’s age on the instrument performance are tested with a series of experiments. Methods: First, 20 eyes from 20 subjects (mean age 26.9 (SD 2.7) years, mean refractive error −1.34 (2.72) D) were examined with the C-Quant straylightmeter, taking 10 consecutive readings. Five subjects were also examined on five consecutive days to assess reproducibility. Additionally, repeated measures of straylight from 84 subjects of ages ranging from 19 to 86 years (mean (SD): 42.4 (24.0) years) were retrospectively analysed to assess the …
RhinAsthma patient perspective: a short daily asthma and rhinitis QoL assessment.
2012
Background The present study aimed to develop a short validated patient-completed questionnaire, the RhinAsthma Patient Perspective (RAPP), to assess the health-related quality of life (HRQoL) in patients with asthma and comorbid allergic rhinitis in clinical practice. Methods A provisional RAPP questionnaire was formed from candidate items identified through retrospective analysis of 333 RHINASTHMA questionnaires. This was then tested on 150 asthma patients with allergic rhinitis. Results Psychometric analyses identified eight items fitting a unidimensional model to form RAPP. Internal consistency (Cronbach's alpha coefficient > 0.8) and agreement with RHINASTHMA (r = −0.31, P = 0.0001) we…
The Panic-Associated Symptom Scale: measuring the severity of panic disorder.
1991
The Panic-Associated Symptom Scale (PASS) is presented as a new measurement of the severity of the core symptoms of panic disorder. This first description addresses the rationale for its design and its scoring, score distributions, test-retest reliability, correlations within the PASS and with other scales, principal component structure, and response to drug therapy. Data are presented from a large study group of patients with panic disorder (n = 1168). Problems in measuring panic disorder are discussed.
HepaDisk – A new quality of life questionnaire for HCV patients
2019
Abstract Background Since most patients with hepatitis C virus (HCV) infection now receive treatment irrespective of liver disease severity, special attention to patient quality of life (QoL), including psycho-social aspects, is required. No QoL questionnaire is specific for patients with HCV. Aims To develop and validate a short Italian questionnaire (HepaDisk) assessing the QoL of patients affected by HCV with intuitive graphic results that is understandable by patients and physicians. Methods A questionnaire, drafted by a steering committee, underwent a Delphi survey. A multicenter, observational study was conducted to validate the developed HepaDisk versus other tools (CLDQ-I, SF-36, WP…
Depression and functional impairment independently contribute to decreased quality of life in cancer patients prior to chemotherapy
2007
An inverse association either between depression or impaired functional status and quality of life (QoL) has been reported for cancer patients, but the independent effect of depression or depressive symptoms and of functional impairment on QoL is unclear.We investigated the prevalence of depression or depressive symptoms with the Beck Depression Inventory (BDI), the functional impairment with the ECOG-Performance-Status (ECOG-PS) and the QoL with the EORTC-QLQ-C30 questionnaire in a sample of 175 hospitalised cancer patients prior to the start of chemotherapy.Sixteen of 175 patients (9.1%) screened positive for major depression, 29 (16.6%) had mild to moderate depressive symptoms. In 11 of …
Two-Year Stability of Psychosis Proneness Scales and Their Relations to Personality Disorder Traits
2000
Two-year stability of Physical Anhedonia (PhA), Perceptual Aberration (PER), and Magical Ideation (MI) scale scores and their relation to personality disorder traits were examined. Additionally, the effects of a time-lagged (prospective) versus concurrent measurement of psychosis proneness and personality disorder traits were studied to examine the specificity of MI, PER, and PhA. With a non-college-student sample (n = 404), stability for PhA was sufficiently high, but for PER and MI, stability was moderate to low. The correlations between personality disorder traits and psychosis proneness scales demonstrate that simultaneous assessment leads to a more nonspecific pattern of associations f…
Initial Evaluation of a Smoking Cessation Program Incorporating Physical Activity Promotion to Greek Adults in Antismoking Clinics
2012
The purpose of this study was to evaluate an initial application of a smoking cessation program that integrated the promotion of physical activity (PA) as a cessation aid to Greek adults in antismoking clinics. From an initial pool of 50, 12 men and 28 women from Central Greece completed the program, and 18 of them succeeded in quitting for 1 year after the program. Additionally, after the program, they increased their PA. Suggestions for future applications of the program are further discussed. peerReviewed
Comparison of the Behavioural Inattention Test and the Catherine Bergego Scale in assessment of hemispatial neglect.
2010
The objective of the study was to correlate visual and behavioural assessments of hemispatial neglect caused by cerebrovascular accident. We assessed 17 consecutive right-hemisphere stroke patients with hemispatial neglect: the Catherine Bergego Scale (CBS) was used to evaluate neglect in spontaneous behaviour and the conventional subtests of the Behavioural Inattention Test (BIT C) were used to assess visual neglect. The proportional severity of both visual and behavioural neglect was calculated in each individual patient. Dissociations were found between mild neglect in visual screening tasks and moderate or severe neglect in behaviour, although in most patients, neglect was equally evide…
