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).
