Peer-Mentoring and Motivational Regulation in Colombian Youth Swimmers

The intervention comprised sixteen weekly face-to-face group peer-mentoring sessions of approximately 20-25 minutes integrated into regular swimming training. An experienced swimmer acted as the peer mentor. Session content included programme introduction and baseline assessment, effective communication, sport stories, SMART goal setting, reflection on competition experiences, a "pool of life" reflective activity, a future-self interview, and a career timeline and programme closure. The SMS-28 was administered before the first session and during the eighth session.

The completed dataset comprised 29 swimmers with paired pre- and post-intervention questionnaires. Seven motivational regulations were examined separately: intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, identified regulation, introjected regulation, external regulation and amotivation.

This study was registered retrospectively after completion of participant enrolment, data collection and analysis. Registration was undertaken for research transparency and should not be interpreted as prospective registration or preregistration.
