Abstract: Aim: The Checklist of Individual Strength (CIS20) is a well validated measure of fatigue severity, which has been adapted in several languages. As Portuguese is one of the most widely spoken languages in the world it is important to have a Portuguese adaptation of the CIS20. Method: Four hundred and thirty healthy Portuguese adults and 89 patients with chronic fatigue (CF) filled out the Portuguese version of the CIS20 (CIS20-P). The CF patients and a subsample of the healthy adults also filled out the SF-12v2 assessing health-related quality of life. Results: The CIS20 four-factor structure was confirmed (subjective experience of fatigue, concentration, motivation and physical activity scales). In general, internal consistency estimates were satisfactory, with the exception of the motivation scale. Moreover, a higher degree of fatigue severity was significantly associated with lower vitality and physical and psychological health-related quality of life. Conclusion: Our results indicate that the CIS20-P is a reliable and valid measure of fatigue severity. Future studies should establish Portuguese cut-off points for sub)clinical levels of fatigue.

Abstract: Patients were seen in two consecutive visits, three to four weeks apart. They were asked to: (i) rate their mean pain intensity in the last 24 hours on an 11-point (0-10) numerical scale; (ii) complete the PV-NPSI; (iii) provide the list of pain medications and doses currently in use. VAS and Global Impression of Change (GIC) were filled out in the second visit.PV-NPSI underwent test-retest reliability, factor analysis, analysis of sensitivity to changes between both visits. The PV-NPSI was reliable in this setting, with a good intra-class correlation for all items. The factorial analysis showed that the PV-NPSI inventory assessed different components of neuropathic pain. Five different factors were found. The PV-NPSI was adequate to evaluate patients with neuropathic pain and to detect clusters of NeP symptoms.The psychometric properties of the PV-NPSI rendered it adequate to evaluate patients with both central and peripheral neuropathic pain syndromes and to detect clusters of NeP symptoms.Neuropathic pain (NeP) probably concerns 7-8% of the general population [1,2]. In addition to a number of patients with various neurological diseases [3], NeP affects significant proportions of patients with diabetes [4], low back pain [5], post-surgical pain [6], cancer [7,8] and some infectious diseases [9] and has a major impact on quality of life.Neuropathic pain syndromes are rather heterogeneous and the relationship between a certain etiology and the symptoms reported by patients are not straightforward. Different symptoms (i.e., allodynia, burning or paroxysmal pain) may coexist in the same patient and may reflect different mechanisms of disease [10]. Consistent with this hypothesis, it has been shown that different symptoms or symptom combinations may respond differently to treatment [11-13]. These data highlight the importance of a specific measurement of neuropathic pain symptoms or neuropathic components, to assess the effects of treatment both in clinical trials and

Abstract: Social Anxiety Disorder (SAD) is prevalent and rarely diagnosed due to the difficulty in recognizing its symptoms as belonging to a disorder. Therefore, the evaluation/screening scales are of great importance for its detection, with the most used being the Liebowitz Social Anxiety Scale (LSAS). Thus, this study proposed to evaluate the psychometric properties of internal consistency and convergent validity, as well as the confirmatory factorial analysis and reliability of the self-reported version of the LSAS (LSAS-SR), translated into Brazilian Portuguese, in a sample of the general population (N = 413) and in a SAD clinical sample (N = 252). The convergent validity with specific scales for the evaluation of SAD and a general anxiety scale presented correlations ranging from 0.21 to 0.84. The confirmatory factorial analysis did not replicate the previously indicated findings of the literature, with the difficulty being in obtaining a consensus factorial structure common to the diverse cultures in which the instrument was studied. The LSAS-SR presented excellent internal consistency (α = 0.90–0.96) and test-retest reliability (Intraclass Correlation Coefficient = 0.81; Pearson’s = 0.82). The present findings support those of international studies that attest to the excellent psychometric properties of the LSAS-SR, endorsing its status as the gold standard.

Abstract: objective: to develop a brazilian version of the gesture behavior test (gbt) for patients with chronic low back pain. methods: translation of gbt into portuguese was performed by a rheumatologist fluent in the language of origin (french) and skilled in the validation of questionnaires. this translated version was back-translated into french by a native-speaking teacher of the language. the two translators then created a final consensual version in portuguese. cultural adaptation was carried out by two rheumatologists, one educated patient and the native-speaking french teacher. thirty patients with chronic low back pain and fifteen healthcare professionals involved in the education of patients with low back pain through back schools (gold-standard) were evaluated. reproducibility was initially tested by two observers (inter-observer); the procedures were also videotaped for later evaluation by one of the observers (intra-observer). for construct validation, we compared patients' scores against the scores of the healthcare professionals. results: modifications were made to the gbt for cultural reasons. the spearman's correlation coefficient and the intra-class coefficient, which was employed to measure reproducibility, ranged between 0.87 and 0.99 and 0.94 to 0.99, respectively (p < 0.01). with regard to validation, the mann-whitney test revealed a significant difference (p < 0.01) between the averages for healthcare professionals (26.60; sd 2.79) and patients (16.30; sd 6.39). there was a positive correlation between the gbt score and the score on the roland morris disability questionnaire (r= 0.47). conclusions: the brazilian version of the gbt proved to be a reproducible and valid instrument. in addition, according to the questionnaire results, more disabled patients exhibited more protective gesture behavior related to low-back.

Abstract: objectives: to evaluate the psychometric properties of the portuguese version of the jebsen-taylor test (jtt) in patients with stroke. methods: forty participants who suffered a stroke in the cerebral hemisphere were videotaped while performing the jtt. scores were defined by the time taken to perform the tasks, and two physical therapists evaluated the performance of the participants. intra- and inter-rater reliability was defined by intraclass correlation coefficients (icc) through videotape analysis. cronbach's alpha and pearson's correlation coefficient (r) were used to measure the internal consistency of the scale. confidence intervals (ci) were calculated, and the influence of handedness and educational level on the jtt scores was evaluated. results: inter-rater (icc = 1.0; ci, 1.0-1.0) and intra-rater reliabilities (icc=0.997; ci, 0.995-0.998) were excellent. regarding internal consistency, cronbach's α was 0.924. the item "writing a sentence" was less consistent than the other items (cronbach's alpha=0.884). pearson's r (item score - total score) was lower for the item "small objects" (r=0.657). there was no significant influence of handedness or educational level on the jtt scores. conclusions: videotaping test performances can be a useful tool in multicenter studies if inter-rater reliability is appropriate. the inter- and intra-rater reliabilities of the portuguese version of the jtt were excellent in patients with stroke. the jtt can be a valuable tool for evaluating dexterity in research protocols aiming at efficacy of rehabilitation interventions.
