Table Key

TSK = Tampa Scale for Kinesiophobia (11 item version)

TSK-SOMFE = TSK subscale somatic focus of ACLR (Items 3, 4, 5, 8)

TSK-FOPE = TSK subscale fear of pain in early phase (Items 6, 7, 9, 11)

TSK-FOIE = TSK subscale fear of injury in early phase (Items 1, 2, 10)

TSK-FOPL = TSK subscale fear of pain in late phase (Items 6, 7, 8, 9, 11)

Shaded area represents data from components not considered for shortened scale

Extraction Method: Principal Component Analysis

Rotation Method: Varimax with Kaiser Normalization (rotation converged in 5 iterations)

Items with loadings of less than 0.45 were suppressed from the table for ease of interpretation
