Measuring individual hierarchy of anxiety invoking sports related activities: development and validation of the Photographic Series of Sports Activities for Anterior Cruciate Ligament Reconstruction (PHOSA-ACLR).

The PHOSA-ACLR showed acceptable measurement properties. The PHOSA-ACLR gives specific information about fear invoking sports situations that are not measured by other kinesophobia measures. Therefore, the PHOSA-ACLR might be a valuable additional tool in rehabilitation of ACLR patients. Additional research is needed to determine responsiveness to change.
