Association Between Catastrophizing and Dizziness-Related Disability Assessed With the Dizziness Catastrophizing Scale.

ABSTRACT: Importance:Catastrophizing is a maladaptive thought process that involves irrational fear and worry about anticipated or actual symptoms. Although clinically relevant, the role of catastrophizing in patients with chronic dizziness or imbalance has not yet been explored to our knowledge. Objectives:To validate a measure of dizziness catastrophizing and to assess its association with dizziness-related disability compared with other negative affect constructs (eg, anxiety and depression). Design, Setting, and Participants:For this retrospective medical record review, the Dizziness Catastrophizing Scale (DCS), a dizziness-specific catastrophizing assessment tool, was adapted from the previously validated Pain Catastrophizing Scale. Psychometric evaluation of the DCS was performed. In addition, the associations of dizziness catastrophizing and positive and negative affectivity with dizziness-related disability were assessed using structural equation modeling and regression analyses. Data were collected using a retrospective medical record review from April 27, 2010, to June 25, 2014. The dates of analysis were June 3 to August 15, 2017. The setting was the Multidisciplinary Neurotology Clinic at the Toronto General Hospital (Toronto, Ontario, Canada). Participants were 457 adult outpatients with dizziness or imbalance who were referred to the clinic. Main Outcomes and Measures:Psychometric properties of the DCS and its association with dizziness-related disability, as measured with the Dizziness Handicap Inventory. Results:Among 457 patients (mean [SD] age, 53.4 [15.4] years; 154 [33.7%] male), the DCS demonstrated good convergent (r = 0.78, P < .001) and discriminant validity (r = -0.40, P < .001) with the negative and positive affectivity, respectively; internal consistency (α = .95); and test-retest reliability (intraclass correlation coefficient, 0.92; P < .001 at the 95% CI). An exploratory dimension reduction analysis revealed a single latent component of the DCS. The results of the structural equation modeling and regression analyses revealed that dizziness catastrophizing, although associated with negative affectivity (eg, symptoms of anxiety and depression), was independently associated with dizziness-related disability (standardized β = 0.378; P < .001). Furthermore, a strong association was found between catastrophizing and dizziness-related disability across different dizziness-related diagnoses (r ≥ 0.6; P < .001). Conclusions and Relevance:In this study, the DCS was a valid and reliable measure for evaluating catastrophic thinking in patients with dizziness, which was independently associated with dizziness-related disability. Future studies should investigate the influence of alleviating symptoms of catastrophizing on functional outcomes in patients with dizziness or imbalance, the results of which will help guide novel approaches to the clinical care of patients with chronic dizziness.

Project description:BackgroundAssociations between dizziness-related handicap and a variety of self-reported measures have been reported. However, research regarding associations between dizziness-related handicap and aspects of functioning that includes both physical tests and self-reported measures is scarce.ObjectiveThe purpose of the study was to describe the variations in signs and symptoms in people with persistent dizziness using physical tests and self-reported outcomes across three severity levels of the Dizziness Handicap Inventory (DHI) and investigate their associations with the DHI.MethodParticipants with persistent dizziness (n = 107) were included in this cross-sectional study. The participants underwent (1) physical tests (gait tests, grip strength, body flexibility, and movement-induced dizziness) and completed questionnaires regarding (2) psychological measures (Mobility Inventory of Agoraphobia, Body Sensation Questionnaire, Agoraphobic Cognitions Questionnaire, and Hospital Depression and Anxiety Questionnaire), and (3) fatigue, dizziness severity, and quality of life (Chalders Fatigue Scale, Vertigo Symptom Scale-Short Form, and EQ visual analog scale), in addition to the DHI. Data were presented by descriptive statistics for three DHI severity levels (mild, moderate, and severe). A multiple linear backward regression analysis was conducted for each group of measures in relation to the DHI total score, with additional analyses adjusting for age and sex. Based on these results, significant associations were tested in a final regression model.ResultsWith increasing severity levels of DHI, the participants demonstrated worse performance on most of the physical tests (preferred and fast gait velocity, dizziness intensity after head movements), presented with worse scores on the self-reported measures (avoidance behavior, fear of bodily sensation, fear of fear itself, psychological distress, fatigue, dizziness severity, quality of life). After adjusting for age and sex, significant associations were found between total DHI and avoidance behavior, psychological distress, dizziness severity, and quality of life, but not with any of the physical tests, explaining almost 56% of the variance of the DHI total score.ConclusionThere was a trend toward worse scores on physical tests and self-reported measurements with increasing DHI severity level. The DHI seems to be a valuable tool in relation to several self-reported outcomes; however, several signs and symptoms may not be detected by the DHI, and thus, a combination of outcomes should be utilized when examining patients with persistent dizziness.

Project description:BackgroundThe impact of long-term dizziness is considerable both on the personal level and in society and may lead to self-imposed restrictions in daily activities and social relations due to fear of triggering the symptoms. Musculoskeletal complaints seem to be common in persons with dizziness, but studies addressing these complaints as a widespread occurrence, are scarce. This study aimed to examine the occurrence of widespread pain in patients with long-term dizziness and investigate the associations between pain and dizziness symptoms. Further, to explore whether diagnostic belonging is related to the occurrence of pain.MethodsThis cross-sectional study was conducted in an otorhinolaryngology clinic and included 150 patients with persistent dizziness. The patients were categorized into three groups: episodic vestibular syndromes, chronic vestibular syndromes, and non-vestibular group. The patients completed questionnaires on dizziness symptoms, catastrophic thinking, and musculoskeletal pain when entering the study. Descriptive statistics were used to describe the population, and associations between pain and dizziness were investigated by linear regression.ResultsPain was reported by 94.5% of the patients. A significantly higher prevalence of pain was reported in all the ten pain sites examined compared to the general population. Number of pain sites and pain intensity were associated with the dizziness severity. Number of pain sites was also associated with dizziness-related handicap, but not with catastrophic thinking. There was no association between pain intensity and dizziness-related handicap or catastrophic thinking. Pain was equally distributed in the diagnostic groups.ConclusionPatients with long-term dizziness have a considerably higher prevalence of pain and number of pain sites than the general population. Pain co-exists with dizziness and is associated with dizziness severity. These findings may indicate that pain should be systematically assessed and treated in patients with persisting dizziness.

Project description:BackgroundChronic low back pain is a worldwide burden that is not being abated with our current knowledge and treatment of the condition. The fear-avoidance model is used to explain the relationship between pain and disability in patients with chronic low back pain. However there are gaps in empirical support for pathways proposed within this model, and no evidence exists as to whether physical activity moderates these pathways.MethodsThis was a cross-sectional study of 218 people with chronic low back pain. Multiple mediation analyses were conducted to determine the role of fear, catastrophizing, depression, and anxiety in the relationship between pain and disability. Separate analyses were performed with physical activity as the moderator. Individuals were classified as performing regular structured physical activity if they described on average once per week for > 30-minutes an activity classified at least moderate intensity (≥ 4-6 METs), activity prescribed by an allied health professional for their back pain, leisure time sport or recreation, or self-directed physical activity such as resistance exercise.ResultsFear, catastrophizing, and depression significantly mediated the relationship between pain and disability (p<0.001). However the mediating effect of catastrophizing was conditional upon weekly physical activity. That is, the indirect effect for catastrophizing mediating the relationship between pain and disability was only significant for individuals reporting weekly physical activity (B = 1.31, 95% CI 0.44 to 2.23), compared to individuals reporting no weekly physical activity (B = 0.21, 95% CI -0.50 to 0.97). Catastrophizing also mediated the relationship between pain and fear (B = 0.37, 95% CI 0.15 to 0.62), with higher scores explaining 53% of the total effect of pain on fear.ConclusionsThese results support previous findings about the importance of fear and depression as factors that should be targeted in low back pain patients to reduce back pain related disability. We have also extended understanding for the mediating effect of catastrophizing on back pain related disability. Back pain patients engaged with regular physical activity may require counselling with regards to negative pain perceptions.
