A revised short version of the Depression Questionnaire (QD/R)
No full textBackground The Depression Questionnaire (QD) is an instrument designed to measure depression in an inpatientrehabilitation
setting. This study proposes a reduced version of the original 24-item QD, to make it better suited to the
characteristics of patients in this setting.
Methods The study population consisted of 801 individuals admitted to cardiac rehabilitation (564 males and 237
females) who had validly completed the original version of the QD. Data were analyzed first through confirmatory factor
analysis and then using logistic models.
Results Factor analysis of QD-24 items form, confirmed the plausibility of the monofactorial solution, both for males and
females. Factor analysis combined with clinical observation suggested the possibility of reducing the QD to 17 items. Two
further items were eliminated through use of simple logistic models. We thus obtained a shortened 15-item version of the
QD (QD-R) that maintains a good index of separation (0.80), that is, good capacity to discriminate between individuals with
different levels of depression, and a good item-trait interaction (v2
153 = 165.37, P > 0.05). A second confirmatory factor
analysis applied to the 15-item monofactorial model confirmed the validity of this shortened version of the instrument. The
QD-R scores significantly correlated with metres walked during the 6 minute walking test (r = – 0.316; P < 0.01).
Conclusion Combined use of confirmatory factor analysis and simple logistic models together with observations drawn
from clinical experience constitutes a valid method for shortening a questionnaire while at the same time maintaining, if
not improving, its psychometric properties. The QD-R, seems adequate to how much is required in rehabilitation to point
out the outcome, in case of variation of depression, easily to fill in by the debilitated individual or elderly, mainly because
some item excessively influenced by the pathology or the hospital context were removed
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Psychophysical health of elderly inpatients in cardiac rehabilitation: A retrospective cohort study
Get PDFBACKGROUND: Elderlies in cardiac rehabilitation show a particular frailty due to specific aging issues, thus specific professional psychophysical care is required. AIM: This study aimed at evaluating the effect of a cardiac rehabilitation program enhanced with psychological support on the psychophysical health of elderly subjects aged ≥75. Moreover, the association of psychophysical conditions with the long-term post-discharge course of medical events was examined. DESIGN: This retrospective cohort study was conducted on elderly patients aged ≥75 admitted from 2015 to 2019 to a cardiac rehabilitation program including psychological support. SETTING: The cardiac ward and the psychology unit of a post-acute clinical rehabilitation Institute. POPULATION: A total of 523 elderly inpatients (44% females), aged ≥75 years (mean 79.7±3.46 years), admitted to a cardiac rehabilitation ward due to heart disease. METHODS: Psychological and functional variables such as depression, quality of life, and Barthel Index were measured at hospitalization and at discharge. The medical events after discharge such as emergency department accesses and rehospitalizations were registered. RESULTS: Cardiac rehabilitation showed significant improvements both in elderlies' psychological and physical health. Higher depression levels predicted a worse post-discharge course. Patients who received psychological intervention accessed emergency department and were rehospitalized significantly later than the others. CONCLUSIONS: Cardiac comprehensive rehabilitation can significantly improve the psycho-physical health of elderly subjects aged ≥75 who benefit of psychological support. Psychological support can enhance the psychophysical health of great elder inpatients in cardiac rehabilitation. CLINICAL REHABILITATION IMPACT: Given the associations with short and long-term outcomes, health professionals should take care of the psychological conditions of elderlies (e.g., depression) by integrating psychological interventions in cardiac rehabilitation in order to promote the elderlies' psychophysical conditions, quality of life, as well as more favorable medical outcomes
