Objective: This study aimed to evaluate the effectiveness of an online multicomponent intervention called FATIGUEWALK (FaW) compared to treatment as usual (TAU) in patients with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). Method: FaWincluded pain neuroscience education, therapeutic exercise, cognitive restructuring, and mindfulness training. A total of 428 patients with CFS/ME were randomized into two study arms: online FaW plus TAU versus TAU alone. A single-blinded randomized controlled trial was conducted. Validated patient-reported outcome measures of fatigue, pain, anxiety, depression, and physical function were collected at baseline and posttreatment, following the FaW intervention, which lasted 12 weeks. Results: Statistically significant improvements (with small-to-moderate effect sizes) were observed in online FaWversus TAU alone with respect to multidimensional aspects of fatigue (Cohen's d ranging from 0.25 to 0.73) and most secondary outcomes (pain and fatigue intensity, depressive and anxious symptomatology, functional impairment, kinesiophobia, physical functioning). The absolute risk reduction in FaWversus TAU was 19%, 95% confidence interval (CI) [12.19, 25.80] with number needed to treat= 6, 95% CI [3.9, 8.2]. Overall, similar clinical improvements were observed in sensitivity analyses including a subgroup of patients without comorbidity with fibromyalgia (n=70). Conclusions: This is the first study to assess the short-term effectiveness of an online multicomponent intervention added to TAU, compared to TAU alone, for the management of CFS/ME. Further trials, including active control groups with an equivalent treatment dose, and assessing the long-term effectiveness of the online FaW, are warranted. [ABSTRACT FROM AUTHOR]

Purpose: To translate and cross-culturally adapt the English version of the Central Sensitisation Inventory (CSI) into Thai (CSI-Thai) and to evaluate its psychometric properties in individuals with chronic non-specific neck pain. Materials and methods: Cross-cultural translation and adaptation of the CSI were performed according to standard guidelines. A total of 340 participants were invited to complete the CSI-Thai, Visual Analogue Scale (pain intensity), Neck Disability Index, Fear-Avoidance Beliefs Questionnaire, Pain Catastrophising Scale (PCS), and Short Form-36. Psychometric evaluation included confirmatory factor analysis, internal consistency, test-retest reliability, agreement, and construct validity. Results: Dimensionality analyses indicated that a bifactor model, comprising one general factor plus four orthogonal factors, fit the CSI structure better than unidimensional and the four-factor models. The general factor showed substantial reliability (Cronbach α=0.91, Omega ω=0.94, and omega hierarchical x-h=0.91). The intraclass correlation coefficient was 0.90, representing excellent stability over a 48 h interval. Moderate-to-strong correlations and acceptable-to-excellent discriminations were found between the CSI-Thai and all questionnaires. The exception was the PCS (no correlation and discrimination). The standard error of measurement and minimal detectable change of the CSI-Thai were 2.33 and 6.47, respectively. Conclusions: The translation and cross-cultural adaptation of the CSI-Thai were successful, with satisfactory reliability and construct validity. [ABSTRACT FROM AUTHOR]

The Fear-Avoidance Components Scale (FACS) is a recently developed patient-reported instrument assessing different constructs related to the fear-avoidance model of pain. The aim was to translate the original English FACS into Dutch (FACS-D) and assess its measurement properties in persons with chronic musculoskeletal pain. The original English FACS (20 item-scale, range: 0–100) was translated in Dutch through standard forward-backward translation methodology. The FACS-D's measurement properties were evaluated in 224 persons with chronic musculoskeletal pain. Internal consistency, test-retest reliability and measurement error were assessed with the Cronbach's alpha coefficient (α), intraclass correlation coefficient (ICC), and standard error of measurement (SEM). Construct validity was assessed through inter-item correlation analyses, exploratory factor analysis, association with other fear-avoidance-related constructs, and hypothesis testing. Internal consistency, test-retest reliability and hypotheses testing were good (α=0.92; ICC=0.92, CI 0.80–0.96; 7/8 hypotheses confirmed). Similar to the original FACS and other translated versions, a two-factor model best fit the data. However, the item distribution differed from other versions. One factor represented "pain-related cognitions and emotions" and a second factor represented "avoidance behaviour." In contrast to the original FACS, low inter-item correlations for item 12 were found. The FACS-D was more strongly associated with fear-avoidance-related constructs of pain severity, perceived disability, feelings of injustice, and depressive/anxiety symptoms than the other fear-avoidance-related scales studied here. The FACS-D demonstrated good reliability and construct validity, suggesting that it may be a useful measure for Dutch-speaking healthcare providers. Two clinically relevant factors, with a different item distribution than the original FACS, were identified: one covering items on pain-related cognitions and emotions, and one covering items on avoidance behaviour. The stronger association between FACS-D and fear-avoidance related constructs suggests that the FACS-D may be more effective in evaluating the cognitive, emotional and behavioural constructs of pain-related fear-avoidance than other similar measures.
