NCT07476430

Brief Summary

The primary aim is to determine if MST will improve coping skills in young athletes returning to sport after ACLR as measured by ACSI-28. Participants will undergo MST led by masters-level mental skills specialist pre-operatively, 3 months, 6 months, and 9 months post-operatively. Power analysis suggested at least 52 pairs are needed (α=0.05, β=0.80). There will be 65 patients enrolled in both the MST group and the control group (no MST) for a total of 130 patients. This will allow for a 4-point difference in ACSI and a 20% dropout rate. The secondary aim is to determine if MST will improve psychological readiness and athletic identity as well as decrease psychological stress, anxiety, depression, and PTSD symptoms of young athletes returning to sport after ACLR as measured by ACL-RSI, AIMS, PROMIS-PSE, GAD-7, PHQ-9, and CRIES, respectively.

Outcome Measures

Primary Outcomes (1)

  • Athletic Coping Skills Inventory (ACSI-28)

    A questionnaire to assess the psychological skills and coping strategies employed by athletes. Scored on a 28-point scale, where higher scores indicate a greater ability to cope.

    The ACSI-28 will be administered preoperatively (baseline) and 9 months, 1 year, and 2 years post operatively.

Secondary Outcomes (8)

  • The Anterior Cruciate Ligament Return to Sport after Injury Scale (ACL-RSI)

    The ACL-RSI will be administered preoperatively (baseline) and at 3 months, 6 months, 9 months, 1 year, and 2 years postoperatively.

  • The Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS)

    The Pedi-FABS will be assessed at baseline, 6 months, 9 months, 1 year, and 2 years

  • PROMIS Psychological Stress Experiences (PROMIS-PSE)

    The PROMIS-PSE will be assessed at baseline, 3 months, 6 months, 9 months, 1 year, and 2 years.

  • Child Revised Impact of Events Scale (CRIES)

    The CRIES will be administered preoperatively (baseline), 3 months, and 6 months.

  • General Anxiety Disorder-7 (GAD-7)

    The GAD-7 will be administered preoperatively (baseline) and at 3 months, 6 months, 9 months, 1 year, and 2 years postoperatively.
