Validity and reliability of the Spanish fear‐avoidance components scale in breast cancer survivors

Objective The aim of this study was to carry out a psychometric analysis the Fear-Avoidance Components Scale (FACS-Sp) in Spanish breast cancer survivors (BCS). Methods A validation carried 154 BCS. Participants were recruited from service Medical Oncology University Clinical Hospital Virgen de la Victoria, Málaga (Spain). internal consistency, structure and convergent validity FACS-Sp performed. Cronbach's alpha calculated for consistency. Exploratory Factor Analysis used determine FACS-Sp. Convergent with Tampa Kinesiophobia (TSK) Pain Catastrophizing (PCS) determined using Pearson correlation coefficient. Results consistency high (McDonald's ω = 0.91). yielded one factor explaining 40.80% total variance. TSK PCS demonstrated. Conclusions has demonstrated be valid reliable measure assessing pain-related fear avoidance BCS based on structural validity. Further studies that analyse other measurement properties different populations are needed.
