An area of emerging interest in chronic pain populations concerns fear of pain and associated fear of movement (kinesiophobia)-a cognitive appraisal pattern that is well-validated in non-headache chronic pain. However, there is limited research on whether this construct can be measured in a similar manner in headache populations. ⋯ The current study is the first to examine the factor structure of the TSK-12 in an adult headache population. The results support the relevance of pain-related fear to the functional and psychosocial status of adults with chronic headache, although model fit of the TSK-12 could be characterized as adequate rather than optimal. Limitations of the study include heterogeneity in headache diagnosis and rates of comorbid non-headache chronic pain in the sample. Future studies should replicate these findings in more homogenous headache groups (eg, chronic migraine) and examine associations with behavioral indices and treatment response.
