In the current study, I examined the efficacy of mindful self-compassion, imagery, and goal-setting (i.e., treatment as usual) interventions on athletic identity, knee self-efficacy, subjective knee functioning, and perceived injustice, following ACL surgery. Twenty-nine adolescent and young adult athletes participated in the interventions and completed self-report measures assessing each of these constructs prior to their surgery and over seven weeks post-ACL surgery. HLM analyses demonstrated significant decreases in athletic identity and increases in subjective knee functioning from pre-surgery through seven weeks post-surgery. Intervention group further explained these decreases, though no one intervention clearly emerged as more or less beneficial. No significant changes were observed for athletes' ratings of knee self-efficacy or perceived injustice. Limitations and areas for future research are discussed.
