<div>Background:<p>Successful return to sports activity after surgery requires both physical and psychological readiness. The Hip–Return to Sport After Injury (Short Form) has been developed to assess psychological readiness to return to sports after hip injury and hip surgery, including hip arthroscopy.</p>Purpose:<p>To evaluate the reliability, validity, responsiveness, and interpretability of the scale for a cohort of patients after hip arthroscopy with a range of sports participation levels.</p>Study Design:<p>Cohort study (diagnosis); Level of evidence, 2.</p>Methods:<p>Invitations to participate were sent to 145 patients from 3 specialist surgeons. The study included 77 participants 1 to 24 months after hip arthroscopy (mean ± SD age, 35 ± 9 years; 62% women) and 33 healthy age-matched controls (age, 37 ± 7 years; 52% women). The scale was administered electronically on 3 occasions to patients: baseline (≥1 month postarthroscopy), 1 week later, and 6 months later. In addition to the scale, participants were asked about sports participation status and their global rating of postsurgical change. The scale was administered to healthy controls on 1 occasion. The minimal detectable difference, discriminant validity, floor and ceiling effects, responsiveness, and interpretability (minimally important change) were determined for the scale.</p>Results:<p>Among the postarthroscopy group, excellent test-retest reliability was found (intraclass correlation coefficient = 0.869; 95% CI, 0.756-0.932) with a minimal detectable difference of 26 points out of 100 at the individual level and 4 points out of 100 at the group level. At baseline discriminant validity was evident between those who had returned to sports (median = 69, n = 35) and those who had not returned to sports (median = 30, n = 42; Mann-Whitney <i>U</i> score = 232.5, <i>z</i> = −5.141, <i>P</i> < .001) and between the returned-to-sports postarthroscopy group and healthy controls (median = 96, n = 33; Mann-Whitney <i>U</i> score = 165.500, <i>z</i> = 5.666, <i>P</i> < .001). No floor or ceiling effects were evident. Responsiveness was demonstrated for the scale in relation to sports status. With sports status as an anchor, a minimally important change of 26 points was identified.</p>Conclusion:<p>Assessment of the Hip–Return to Sport After Injury (Short Form) supports its use as a reliable and valid measure of psychological readiness to return to sports in patients after hip arthroscopy.</p></div>
