| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Patient Self-Administered Exam Group | Experimental | Participants with hip pain presenting in the hip preservation clinics will be asked to complete two diagnostic exams. Participants with hip pain will first complete a patient self-administered diagnostic exam. |
|
| Clinician-Performed Exam Group | Active Comparator | Participants with hip pain presenting in the hip preservation clinics will be asked to complete two diagnostic exams. Participants with hip pain will next complete a clinician-performed diagnostic exam. |

|---|---|---|---|---|
| Patient Self-Administered Diagnostic Exam | Other | Participants will complete a patient self-administered diagnostic exam. A physician will be available to monitor the patient and record findings but will not physically assist the participants. |
| Measure | Description | Time Frame |
|---|---|---|
| Sensitivity | As measured by a questionnaire evaluating the diagnostic test's ability to identify a positive finding when the targeted diagnosis is actually present (i.e. true positive). | End of clinician examination, 20 minutes |
| Measure | Description | Time Frame |
|---|---|---|
| Specificity | As measured by the discriminatory ability of the diagnostic test to identify if the disease or condition is absent when in actuality it is truly absent (i.e. true negative). | End of clinician examination, 20 minutes |
| Diagnostic accuracy measure of positive likelihood ratio |

As measured by sensitivity and specificity values. |
| End of clinician examination, 20 minutes |
| Diagnostic accuracy measure of negative likelihood ratio | As measured by sensitivity and specificity values. | End of clinician examination, 20 minutes |
| Diagnostic accuracy measure of post-test probabilities | As measured by analysis of the pre-test prevalence of the condition and determination of the post-test shift in probability of the condition. | End of clinician examination, 20 minutes |
