Development of a multidimensional measure of fibromyalgia symptomatology: the comprehensive rating scale for fibromyalgia symptomatology.

OBJECTIVE: Fibromyalgia (FM) is characterized by a heterogeneous group of clinical symptoms that are evaluated using a wide variety of instruments. This study sought to develop and validate a new scale, the Comprehensive Rating Scale for Fibromyalgia Symptomatology (CRSFS), to facilitate the joint evaluation of the most frequent symptoms in patients with FM. METHODS: CRSFS items were based on a literature review and a focus group composed of patients and healthcare professionals. Four samples of patients (FM, non-FM rheumatic pain, depression, and healthy volunteers) were used to study the reliability and validity of the CRSFS. The factor structure of the CRSFS was determined through exploratory and confirmatory factor analyses. The test-retest and inter-examiner reliabilities were evaluated in a subsample of participants with FM. The criterion and convergent construct validity were compared using valid and reliable instruments to assess the impact of FM on quality of life, pain, fatigue, mood, and quality of sleep. The capacity to differentiate groups of patients was examined by comparing the CRSFS scores of the four samples to each other and using receiver operating characteristics curves. RESULTS: The sample was composed of 240 participants, the mean age was 49.1years (SD=10.4), and 97.5% of them were women. The factor analyses, as well as the tests of reliability and validity, were positive. The final version of the CRSFS consisted of 20 symptoms evaluated using 60 items. CONCLUSION: The CRSFS is a valid and reliable 4-factor scale that evaluates the most frequent clinical symptoms of patients with FM.

[Subtypes of patients with fibromyalgia, psychopathological characteristics and quality of life]. / Subtipos de pacientes confi bromialgia, característicaspsicopatológicas y calidad de vida.

INTRODUCTION. The main goal of this work was to identify subgroups of patients with fibromyalgia (FM) by means of a frequently used clinical tool, the Fibromyalgia Impact Questionnaire (FIQ). METHODOLOGY. A total of 66 women diagnosed with FM participated in the study. Two subgroups of patients were identified by analysis of a hierarchical cluster of selected items from the FIQ (pain, fatigue, morning tiredness, stiffness, anxiety and depressive symptoms). RESULTS. The type I FM-group had very high levels of fatigue, morning tiredness and anxiety, and high levels of joint stiffness, pain and depressive symptoms, while the type II FM-group had predominantly moderate levels of fatigue and morning tiredness, with moderate low levels of pain and stiffness along with a low level of depression and anxiety. CONCLUSIONS. Type I FM-group also had lower healthrelated quality of life, especially through emotional reactions and social isolation as well as more psychopathological affections than presented by type II FM-group.

The goals of this study are the preliminary Spanish adaptation and validation of the following questionnaires: the Children's Eating Attitudes Test (ChEAT), the Lawrence Self-Esteem Questionnaire (LAWSEQ) and the Body Esteem Scale (BES). In addition, we studied bodily self-esteem in pre-adolescent children, and their possible relation to certain eating attitudes and general self-esteem. This study is cross-sectional, analytical and observational. The sample was made up of 457 participants, 55.14% boys and 44.86% girls aged between 8 and 12 (M = 10.14, SD = 1.30). A multivariate analysis of variance (Age x Sex) was carried out with the total scores of LAWSEQ, ChEAT, BES, BIA and BMI. Cronbach's alpha reliability coefficient was .76, .80, and .67 for ChEAT, BES, and LAWSEQ, respectively. The boys presented significantly higher total scores in the ChEAT than the girls. Of the sample, 10.4% (n = 45) scored over the cut-off point of the ChEAT: These subjects presented lower general and bodily self-esteem, a slimmer ideal image and a greater discrepancy between their real self and their social self.
