A further Rasch analysis of the Fear-Avoidance Beliefs Questionnaire in adults with chronic low back pain suggests the revision of its rating scale
No full textObjective: To examine the psychometric properties of the Fear-Avoidance Beliefs Questionnaire (FABQ) and its two subscales, in subjects with chronic low back pain (LBP).
Design: Methodological research based on a cross-sectional observational study.
Methods: A convenience sample of 155 Italian subjects with chronic LBP (57% men; mean age: 43±11 years; mean pain duration: 23±32 months) completed the FABQ. Rasch analysis was used to investigate dimensionality of the entire scale and key psychometric properties of its two subscales.
Results: The FABQ-Physical Activity (FABQ-PA) and FABQ-Work (FABQ-W) subscales showed two distinct unidimensional structures. Their 7-option rating categories were malfunctioning, but after collapsing problematic categories and omitting the central one ("Unsure") the new 4 categories (completely disagree; disagree; agree; completely agree) functioned as intended. After that and accommodation of local response dependency between two items in a testlet solution, each of the two subscales presented acceptable fit to the Rasch model (just one FABQ-W items was slightly underfitting). Person separation reliability was acceptable but not high (0.69 for FABQ-PA, and 0.79 for FABQ-W).
Conclusions: FABQ-PA and FABQ-W have adequate unidimensionality. A simplification of the response options of both subscales is strongly recommended to improve the technical quality of the scale. The reliability indexes suggest FABQ-PA and FABQ-W can be used for group judgements about level of fear-avoidance beliefs, but not for clinical decision-making in individuals. The selection of their items is acceptable, although - if future studies corroborate our results - there is room for some refinements to improve the general measurement quality.
Clinical rehabilitation impact: Fear-avoidance beliefs are associated with reduction of physical activity, and development of disability and deconditioning. This study examined the measurement properties of the two FABQ subscales, showing their essential unidimensionality, recommending the simplification of the rating categories, and discussing strengths and weaknesses of item selection. Our results extend the evidence for FABQ as a satisfactory (but improvable) measure of fear-avoidance beliefs in chronic LBP
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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

Full text linkUpper limb lymphedema (ULLy) is an external (and/or internal) manifestation of lymphatic system insufficiency and deranged lymph transport for more than 3 months and frequently affects people as a consequence of breast cancer (BC). ULLy is often underestimated despite diminished motor skills, mood, and cognitive-behavioral complaints negatively condition the health-related quality of life (HRQoL) of persons. BC can also metastasize to the jawbone, further impacting on the HRQoL. In time, the implementation of robot-assisted rehabilitation (RR) for neurological diseases has grown to improve HRQoL and pain. This study aims to evaluate the effectiveness of a RR program in the treatment of individuals who develop an ULLy; as a further analysis, the study will assess the effectiveness of the same program in people with jawbone metastases from BC who will also develop ULLy. A randomized, parallel-group superiority-controlled trial will be conducted. 44 participants will be randomly allocated to either the experimental (receiving a RR program) or the control group (regular rehabilitation). Both groups will follow individual-based programs three times a week for 10 weeks. The main outcome measure will be the Lymphedema Quality of Life Questionnaire. Secondary outcomes will be a pain intensity numerical rating scale and the Cranio-Facial Pain Disability Inventory. Evaluations are before and after training and 6 months later. Findings may provide evidence on the effectiveness of a RR program on inducing improvements in the HRQoL and pain of individuals with ULLy due to BC. People with ULLy and jawbone metastases from BC are expected for similar or higher improvements as per the same comparisons above. This trial might contribute towards defining guidelines for good clinical rehabilitation routines and might be used as a basis for health authorities' endorsements.Trial registration OSF REGISTRIES, osf-registrations-jz7ax-v1 .

Variations on the Author
Full text link“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
Full text linkWe 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
Cognitive Rehabilitation Integrated with Motor Rehabilitation in Oncological People
Full text linkUsual anticancer therapies may result in cancer-related cognitive impairment, or worsen it if the patient is already affected. Cognitive rehabilitation is the most effective way of dealing with cognitive impairment, especially together with motor rehabilitation. A patient-centred care approach will give even better results. Neuropsychological rehabilitation starts after an evaluation of the patient’s cognitive, psychological and behavioural function levels by a psychologist. In this context, mindfulness, yoga and meditation can be helpful supporting activities. The process is completed by motor rehabilitation, according to the biopsychosocial pattern, which is based on the interaction of biological, psychological and socio-cultural factors. For instance, the execution of motor exercise creates new sinaptic connections, strengthening brain functions.Usual anticancer therapies may result in cancer-related cognitive impairment, or worsen it if the patient is already affected.

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
