A computerized version of the Patient Health Questionnaire-4 as an ultra-brief screening tool to detect emotional disorders in primary care
2018
Abstract Background The Patient Health Questionnaire-4 (PHQ-4) is an ultra-brief self-report consisting of a 2-item depression scale (PHQ-2) and a 2-item anxiety scale (GAD-2). The aim of the present study is to determine the psychometric properties of a computerized version of the PHQ-4 used to detect emotional disorders (anxiety and depression) in the primary care setting. Method A total of 1052 patients with suspected anxiety, depression, or somatic symptoms were recruited from 28 primary care centres participating in the PsicAP trial and completed the full version of the computerized PHQ. In addition, 178 of these patients also underwent in clinical interviews as a gold standard. Result…
Psychometric properties of the Haitian Creole version of the Resilience Scale with a sample of adult survivors of the 2010 earthquake
2015
Abstract Background Resilience is defined as the ability of people to cope with disasters and significant life adversities. The present paper aims to investigate the underlying structure of the Creole version of the Resilience Scale and its psychometric properties using a sample of adult survivors of the 2010 earthquake. Methods A parallel analysis was conducted to determine the number of factors to extract and confirmatory factor analysis was performed using a sample of 1355 adult survivors of the 2010 earthquake from people of specific places where earthquake occurred with an average age of 31.57 (SD = 14.42). All participants completed the Creole version of Resilience Scale (RS), the Imp…
Reliability and validity of the form 90 interview.
2004
<i>Objective:</i> Alcohol consumption is a central variable in substance abuse research and treatment. The study reports the psychometric characteristics of the German version of the Form 90 interview for the assessment of recent alcohol consumption. <i>Method:</i> Reliability was evaluated in a test-retest study (7 days) with 30 consecutively admitted psychiatric inpatients with alcohol dependence. Validity of Form 90 was assessed with a second sample of 60 alcohol-dependent inpatients. <i>Results:</i> Form 90 demonstrated good to excellent retest reliability for the central variables of alcohol consumption. Retest reliability Pearson correlation coeffic…
Hyperthymic temperament may protect against suicidal ideation.
2010
Abstract Background The aim of this study was to investigate the role of hyperthymic temperament in suicidal ideation between a sample of patients with affective disorders (unipolar and bipolar). Method We investigated affective disorders outpatients (unipolar, bipolar I, II and NOS) treated in eleven participating centres during at least a six-month period. DSM-IV diagnosis was made by psychiatrists experienced in mood disorders, using the corresponding modules of the Mini International Neuropsychiatric Interview (MINI). In addition, bipolar NOS diagnoses were extended by guidelines for bipolar spectrum symptoms as proposed by Akiskal and Pinto in 1999. Thereby we also identified NOS III (…
Weekly monitoring of dexamethasone suppression response in depression: its relationship to change of body weight and psychopathology
1985
Abstract Weekly dexamethasone suppression tests (DST) were performed in 19 hospitalized patients with major depressive disorder, endogenous subtype, and who had an abnormal DST at admission. Depression scores (Hamilton Rating Scale) and weight changes were collected by investigators who were blind to the test results. Major findings were: (1) the DST gradually normalized 3–4 weeks prior to full resolution of clinical symptomatology; (2) weight loss was an important patient variable which may have contributed to false positive DST results; however, the positive correlation between changes in DST results and changes in depression scores in all our patients with or without weight loss suggests…
Improvement of inter-rater reliability of PANSS items and subscales by a standardized rater training.
1998
The present evaluation focused on the inter-rater reliability of single items and subscales of the Positive and Negative Syndrome Scale (PANSS) before and after a standardized rater training. The results of two independent studies comprising n=23 (study I) and n=12 (study II) psychiatrists and videotaped interviews with schizophrenic patients were analysed. Chance-corrected coefficients of rating agreement with expert standards (weighted kappa) were computed for single items and subscales of the PANSS. The results clearly demonstrate the importance of rater trainings. After three training sessions, 90% of the PANSS items reached an acceptable level of reliability (kappa(w)>0.40) in both eva…
Objective measurement of intraocular forward light scatter using Hartmann-Shack spot patterns from clinical aberrometers. Model-eye and human-eye stu…
2007
Purpose To apply software-based image-analysis tools to objectively determine intraocular scatter determined from clinically derived Hartmann-Shack patterns. Setting Aston Academy of Life Sciences, Aston University, Birmingham, United Kingdom, and Department of Optics, University of Valencia, Valencia, Spain. Methods Purpose-designed image-analysis software was used to quantify scatter from centroid patterns obtained using a clinical Hartmann-Shack analyzer (WASCA, Zeiss/Meditec). Three scatter values, as the maximum standard deviation within a lenslet for all lenslets in the pattern, were obtained in 6 model eyes and 10 human eyes. In the model-eye sample, patterns were obtained in 4 sessi…
The development of a Spanish language version of the Worn Out scale of the General Well-Being Questionnaire (GWBQ).
2006
The paper describes the development of a short Spanish-language version of the General Well-Being Questionnaire (GWBQ; Cox & Gotts, 1987), based on the 12 items of its Worn Out scale. Research has shown the English-version Worn Out scale to be sensitive to aspects of the design and management of work. This study aimed to test its cross-cultural consistency in a Spanish-language workplace context. The data were collected from a sample of 229 workers in Valencia (Spain). Confirmatory Factor Analyses showed the factorial validity, reliability, and concurrent validity of the new Spanish version to be adequate. The sensitivity of the new measure to safety behavior and the reporting of accide…
The Spanish-Version of the Subjective Vitality Scale: Psychometric Properties and Evidence of Validity.
2017
AbstractThe Subjective Vitality Scale (SVS) assess the subjective experience of being full of energy and alive, a clinically relevant outcome measure of positive psychological well-being. The purpose of this paper was to translate the 7-item SVS into Spanish and examine its psychometric properties. In Study 1 (n = 790 adolescents) and Study 2 (n = 130 athletes) reliability and exploratory factor analysis (EFA) were carried out. In Study 1 and Study 3 (n = 197 dancers) evidence of validity of inferences based on SVS scores estimating relationships with other variables (life satisfaction, global self-esteem and emotional and physical exhaustion) was obtained. In Study 2 invariance across time…
Is the breadth of individualized ranges of optimal anxiety (IZOF) equal for all athletes? A graphical method for establishing IZOF.
2001
Recall and direct methods to determine the individual zone of optimal functioning (IZOF) cannot account for potential individual differences in the span of optimal anxiety. Accordingly, an attempt was made to test a graphical technique that could establish the span of optimal anxiety ranges for individuals. State anxiety (STAI; Spielberger, Gorusch, & Lushene, 1970; and CSAI-2; Martens, Burton, Vealey, Bump, & Smith, 1990) was assessed before competitions (10 to 20) in six Spanish golfers during a season. Performance in each match was determined using golf scores and self-ratings. Optimal anxiety ranges were established graphically by plotting individual scores of precompetition anx…
