Tampa Scale for Kinesiophobia for Pelvic Pain (TSK-PP). Adaptation, Translation, and Psychometric Validation.

Pelvic pain is a complex condition that can significantly impact daily functioning and quality of life. Fear of movement, or kinesiophobia, is recognized as a key psychological factor that may contribute to the transition from acute to chronic pain by promoting avoidance behaviors and limiting physical activity. Accurate measurement of kinesiophobia in patients with pelvic pain is essential for both clinical assessment and research purposes.

The Tampa Scale for Kinesiophobia (TSK) is a widely used instrument for assessing fear of movement, but its original items focus on general or musculoskeletal pain and do not capture the specific concerns of patients with pelvic pain. To address this gap, this study aims to adapt and translate the TSK for application in this population (TSK-PP) and evaluate its psychometric properties.

The study involves a rigorous process of cultural adaptation and translation, including item modification to reflect pelvic pain-specific contexts, forward translation into Spanish, independent review by an external expert, and back-translation into English to ensure conceptual equivalence. Following translation, the TSK-PP will be administered to adult patients with pelvic pain, alongside measures used for construct validation, including the Fear-Avoidance Beliefs Questionnaire (FABQ) and the Pain Catastrophizing Scale (PCS).

Data collected will include demographic and clinical characteristics such as age, sex, marital status, medical diagnosis, duration and severity of pelvic pain. These variables will allow for sample characterization and exploration of relationships with TSK-PP scores during psychometric evaluation.

This study will provide evidence on the reliability, validity, and applicability of the TSK-PP for assessing kinesiophobia in individuals with pelvic pain, supporting its use in both clinical practice and research settings.
