Adaptation and validation of the Patient Health Questionnaire-9 to evaluate major depression in a primary care sample in Latvia
2017
Background: Depression is one of the most common mental disorders in primary care settings and is often underdiagnosed and undertreated by general practitioners (GPs). To date, no depression screening instruments have been validated for use in primary care settings in Latvia. The aim of this study was to establish the validity and cutoff score of the Patient Health Questionnaire-9 (PHQ-9) among primary care patients in Latvia. Materials and methods: During a one-week period, all consecutive patients aged 18 years or older visiting their GP of health concerns at 6 primary care settings were invited to complete the PHQ-9 questionnaire in their native language (Latvian or Russian). Criterion v…
Rasch validation of the Depression Scale among patients with low back pain.
2020
BACKGROUND: The Depression Scale (DEPS) is a commonly used screening tool for major depression in studies investigating low back pain, yet it has not been validated for patients with back-specific problems. OBJECTIVE: To assess the psychometric properties of the DEPS in patients with degenerative spinal disease. METHODS: Six hundred and thirty-seven patients with a degenerative spinal disease completed the DEPS instrument. The Rasch Measurement Theory was applied to analyze the measurement properties of the DEPS. The main hypothesis-driven approach was whether the DEPS would meet relevant psychometric criteria for assessing depressive symptoms among patients with degenerative spinal disease…
Reliability and validity study of the Finnish version of the Chronic Pain Acceptance Questionnaire (CPAQ).
2012
Acceptance has been discovered to be successful in improving quality of life when adjusting to chronic pain. Instead of avoiding and controlling the pain, the goal is to confront the pain and to live a value directed life. Thus far, there has not been an instrument in Finnish to assess the acceptance of chronic pain. This study aimed at translating the Chronic Pain Acceptance Questionnaire-(CPAQ)-into Finnish and assessing its reliability and validity.Eighty-one persons with different types of chronic pain responded to the CPAQ, the Beck Depression Inventory (BDI), RAND-36 and questions of sociodemographic and pain-related variables.The responders' ages varied from 16 to 83 years (mean = 48…
A SCAN-SADS comparison study of psychotic subjects and their first-degree relatives
1993
Two diagnostic interviews, the Schedule for Affective Disorders and Schizophrenia (lifetime version) (SADS-LA) and the Schedule for the Clinical Assessment of Neuropsychiatry (SCAN) were compared for main diagnoses and for their acceptibility to psychotic subjects and their psychiatrically well relatives. Broad agreement for DSM-III, DSM-III-R and draft ICD-10 diagnoses was good, although there were areas of disagreement between the two interviews which are discussed.
Measurement invariance, validation and normative data of the Jenkins Sleep Scale-4 (JSS-4) in the German general population across the life span.
2019
Abstract Objective As sleep disorders have become a major concern in public health, there is strong need for a brief and sound measure for sleep problems. The purposes of the study were to 1) evaluate factor structure and measurement invariance, 2) validate the scale based on sociodemographic data and distress, and 3) provide norm values for the general population. Methods In a representative survey of the German population N = 2515 participants (14 to 95 years) filled in the 4-item Jenkins Sleep Scale (JSS-4), sociodemographic questions and the Brief Symptom Inventory-18 (anxiety, depression, somatic symptom load). The JSS-4 was analyzed by principal component analysis, confirmatory and mu…
Confirmatory factor analysis and psychometric properties of the Yale–Brown–Cornell Eating Disorders Scale Self-Report version (SR-YBC-EDS) in Spanish…
2015
[EN] Objective: The aimof the study was to adapt and validate the Yale Brown Cornell Eating Disorder Scale (YBC-EDS) transformed into a self-report format in Spanish clinical and non-clinical samples. Method: Eighty-three eating disordered patients and 358 non-clinical participants completed the Self Report-YBCEDS version (SR-YBC-EDS), the Eating Attitudes Test (EAT), and the Penn State Worry Questionnaire (PSWQ). Results: Confirmatory factor analyses of a two-factor second-order model showed adequate values of goodness-of fit indices for non-clinical (normed ÷2=13.4578; df=18; NFI=0.980; GFI=1.00; RMSEA= 0.00) and clinical samples (normed ÷2 = 26.5913; df =18; NFI = 0.944; GFI = 0.981; RMS…
Hepatic focal nodular hyperplasia: contrast-enhanced ultrasound findings with emphasis on lesion size, depth and liver echogenicity
2010
To correlate contrast-enhanced ultrasound (CEUS) findings of hepatic focal nodular hyperplasia (FNH) with lesion size, depth and liver echogenicity and to compare CEUS with baseline US. Two radiologists evaluated baseline US and CEUS examinations of 92 FNHs (mean size: 3.1 +/- 1.7 cm) in 71 patients (59 women and 12 men) to detect the "spoke-wheel" sign, central scar and feeding vessel. The FNHs were grouped and analysed by dimension, depth and liver echogenicity. At least one sign could be detected at CEUS in 27 out of 36 (75%) FNHs larger than 3 cm and in 17 out of 56 (30%) FNH measuring 3 cm or less (p 0.05) as well as between CEUS or baseline US/CD with regard to lesion size, depth or l…
Comparison of subjective olfaction ratings in patients with and without olfactory disorders
2012
AbstractObjective:Olfactory dysfunction is common. The reliability of self-assessment tools for smell testing is still controversial. This study aimed to provide new data about the accuracy of olfactory self-assessment compared with a standardised smell test.Design:Prospective, controlled, cohort study of patients with olfactory disorders and healthy controls.Subjects:Ninety-six patients with a smell deficit and 71 controls were asked to rate their sense of smell on a visual analogue scale. Their olfactory abilities were also evaluated with the Sniffin' Sticks tests.Results:The whole cohort showed a significant correlation between visual analogue scale smell scores and Sniffin' Sticks total…
The spectrum of circadian blood pressure changes in type I diabetic patients.
2001
Background The objective of the present study was to characterize the spectrum of circadian blood pressure changes in type I diabetes at different stages of nephropathy by using two monitorings in each patient in order to avoid intra-individual variability. Patients and methods A total of 80 type I diabetic subjects and the same number of age, sex and awake mean blood pressure (BP)-matched controls were included. According to urinary albumin excretion, there were 57 normoalbuminurics, 15 persistent microalbuminurics and eight proteinurics. Two 24 h ambulatory blood pressure monitorings were performed at the same urinary albumin excretion stage in absence of antihypertensive treatment for ea…
Non-Invasive Assessment of Coronary Artery Bypass Grafts and Native Coronary Arteries Using 64-Slice Computed Tomography: Comparison With Invasive Co…
2010
Introduction and objectives Although the diagnostic accuracy of CT in the non-invasive assessment of coronary arteries and grafts is known to be high, only a few studies have investigated the technique's reliability for the combined assessment of native coronary arteries, grafts, and vessels lying distal to anastomoses. The aim of this study was to evaluate the diagnostic accuracy of 64-slice CT for assessing coronary grafts and native coronary arteries. Methods In the study, 64-slice CT was used to evaluate 36 patients who had undergone coronary artery bypass graft surgery and had a clinical indication for angiographic graft assessment. The diagnostic accuracy of CT for identifying signifi…
