Numerous studies have found kinesiophobia in patients with vestibular disorders. This research study aimed to develop and measure the psychometric properties of the Tampa Scale of Kinesiophobia (TSK-11), for use in persons with dizziness (TSKd).MethodsAn observational validation study of questionnaires was carried out including 211 participants with dizziness. After adapting the TSK-11 items to the symptoms of dizziness, the construct validity was evaluated with principal component analysis (PCA), internal consistency with the calculation of Cronbach's alpha, test-retest reliability with the intraclass correlation coefficient (ICC), concurrent validity with Spearman correlation and predictive validity with ROC curve analysis.ResultsThe PCA retained 10 items from the original scale with a three-factor structure that mediates fear (TSKd_f), negative thoughts (TSKd_n) and avoidance (TSKd_a). Cronbach's alpha was 0.810 for the 10-item TSKd. Reproducibility was moderate to substantial, with ICCs between 0.69 and 0.84. The TSK showed strong correlations with the DHI, while correlations with other dizziness measures were moderate. A TSKd score >25 and TSKd_f score >9 showed good predictive capacity, with an area under the curve (AUC) ROC of 0.85 and a sensitivity and specificity between 0.85 and 0.70.ConclusionsThe TSKd is a tool available for measuring kinesiophobia in persons with dizziness. Both the 10-item TSKd and the 4-item TSKd_f scales have good psychometric properties.</p>","PeriodicalId":49960,"journal":{"name":"Journal of Vestibular Research-Equilibrium & Orientation","volume":" ","pages":"300-312"},"PeriodicalIF":3.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144545844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anxiety (ANX) and depression (DEP) are common with dizziness, vertigo, or imbalance. It is unclear whether self-reported anxiety or depression depends on perceived physical function for individuals participating in vestibular rehabilitation (VPT). We hypothesized that individuals with worse physical function would be more likely to report abnormally high anxiety and/or depression levels.Participants170 individuals referred for vestibular rehabilitation (113 female, 57 males, and age 63.7 (21)).MethodsA retrospective chart review extracted age, Patient-Reported Outcome Measurement Information System (PROMIS) scores (ANX, DEP, physical function) and primary diagnoses [benign paroxysmal positional vertigo (<i>n</i> = 42), unilateral vestibular hypofunction (<i>n</i> = 39), bilateral vestibular hypofunction (<i>n</i> = 14), concussion/head injury (<i>n</i> = 7), dizziness/vertigo (<i>n</i> = 37), and imbalance (<i>n</i> = 31)]. Average PROMIS scores and percentage of abnormal scores were calculated for physical function, ANX, and DEP scores and reported using descriptive statistics. Logistic regression was performed to separately examine the odds of abnormal ANX and DEP based on abnormal physical function while controlling for age and sex, on the entire dataset and on diagnosis subgroups.ResultsIndividuals referred to vestibular physical therapy with self-reported abnormal physical function were more likely to have abnormal ANX (OR 5.1, <i>p</i> < 0.001) or DEP (OR 3.10, <i>p</i> = 0.002). Older adults were less likely to have abnormal ANX (OR = 0.96, <i>p</i> = 0.002). For individuals experiencing BPPV (<i>n</i> = 42), those with abnormal physical function are more likely to report ANX (OR 9.9, <i>p</i> = 0.009). For individuals with UVH (<i>n</i> = 39), those with abnormal physical function were more likely to report ANX (OR 10.1, <i>p</i> = 0.008) or DEP (OR 9.9, <i>p</i> = 0.010).ConclusionSelf-reported abnormal physical function corresponds to a higher incidence of abnormal ANX and DEP for individuals referred to VPT. Individuals with benign proximal positional vertigo and unilateral vestibular hypofunction were approximately 10 times more likely to experience abnormally high ANX or DEP compared to all other primary diagnosis. Clinicians seeing patients in VPT should be screening for anxiety and depression especially for those with self-reports of impaired physical function.</p>","PeriodicalId":49960,"journal":{"name":"Journal of Vestibular Research-Equilibrium & Orientation","volume":" ","pages":"320-327"},"PeriodicalIF":3.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12353977/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144095621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
