Although fatigue usually goes unnoticed, it is a symptom that poses great challenges to patients with fibromyalgia and is a strong limitation. The aim of this study is to identify and describe the variables involved in fatigue in nine different situations of the Goal Pursuit Questionnaire (GPQ) that may occur in the daily lives of women with fibromyalgia, according to an ABC (Antecedents–Behaviors–Consequences) model. This study followed a qualitative descriptive research method and a deductive–inductive hybrid approach based on a phenomenological paradigm. Twenty-six women with fibromyalgia participated in focus group discussions between February and March of 2018. Thematic content analysis was carried out from transcribed verbatim interviews. We identified nine major themes that emerged from the participants’ conversations: self-imposed duties, muscle fatigue, overwhelming feeling of tiredness, difficulty thinking, difficulty concentrating, negative emotions, lifestyle changes, affected everyday activities, and lack of motivation for daily activities and social interactions. We conclude that the ABC model allowed certain elements to emerge regarding the fatigue experience, highlighting its importance as a symptom in fibromyalgia. This additional analysis of the ABC model showed that fatigue can be described through the 4 U’s Rule, which is integrated by these four adjectives: (1) Unpredictable, (2) Uncontrollable, (3) Unseen, and (4) Unintelligible. Identifying these characteristics can contribute to a better understanding of fibromyalgia in addition to better treatment for these patients.
Objectives: Along with the symptoms of pain and fatigue, pain catastrophizing and avoidance behaviors are highly prevalent and associated with functional impairment in fibromyalgia (FM) patients. Although pain and fatigue affect patients' quality of life, research has been exclusively focused on how pain affects physical activity and exercise. The aim of this study was to analyze the role of pain catastrophizing and preference for fatigue-avoidance goals in walking behavior and functional impairment in women with FM.
Materials and Methods:In this cross-sectional study the sample was composed of 76 participants aged 18 years and older (mean age = 55.05, SD = 7.70). The study evaluated pain catastrophizing, preference for fatigue-avoidance goals, functional impairment, and walking behavior along with sociodemographic variables and clinical data.Results: Pain catastrophizing was associated with preference for fatigue-avoidance goals and this preference was associated with greater functional impairment and less distance walked. Path analysis supported the mediating role of preference for fatigueavoidance goals in the relationship between pain catastrophizing and walking behavior and between pain catastrophizing and functional impairment. Furthermore, pain catastrophizing predicted greater preference for fatigue-avoidance goals which predicted more problems in functioning and less distance walked.Discussion: The present study may help clarify the connection between the factors that stop individuals with FM from implementing beneficial behaviors such as walking, and thus, allowing for the design of psychological interventions that seek to maintain physical functioning despite experiencing fatigue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
