About this trial
This study evaluates whether a brief, structured team reflection programme embedded within routine elite underwater rugby training is associated with longitudinal change in key psychosocial team over 6 weeks and assessed at baseline (T0), mid-intervention (week 3; T1) and post-intervention (week 6; T2). Outcomes include team cohesion, psychological safety, peer trust and team identification measured via validated questionnaires.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Male elite underwater rugby athletes aged 18 years or older.
Officially rostered in the squad and training regularly (minimum 2 sessions per week).
Able to complete Spanish-language questionnaires.
Willing to participate and provide written informed consent.
Disqualifiers
Unable to complete the questionnaires reliably (e.g., language/comprehension barriers).
Anticipated prolonged absence during the 6-week period that would prevent meaningful exposure to the intervention and/or completion of follow-up assessments.
Declines participation or does not provide informed consent.

Treatments tested in this trial
Usual elite underwater rugby training
BehavioralOngoing routine team training delivered during the 6-week study period according to the team's normal training plan (e.g., in-water technical/tactical practice and dry-land conditioning as typically scheduled). Training content is not modified for research purposes. Training attendance and any major deviations (e.g., cancellations, unusual loads) are recorded as part of routine monitoring.

Trial outcomes
Primary outcomes
1
Team Cohesion (GEQ-12 short form)
Team cohesion measured using the Spanish 12-item short form of the Group Environment Questionnaire (GEQ). Items are rated on a 1-9 scale; negatively keyed items are reverse-scored. A composite cohesion score is computed as the mean of items, with higher scores indicating greater perceived cohesion.
Time frame
Baseline (T0, pre-intervention; up to 5 minutes), Week 3 (T1; up to 5 minutes), and Week 6 (T2, post-intervention; up to 5 minutes)Secondary outcomes
1
Psychological Safety (Edmondson 7-item Team Psychological Safety scale)
Psychological safety assessed with the 7-item Team Psychological Safety scale. Items are answered on a 1-7 Likert-type response format; negatively keyed items are reverse-scored. A composite psychological safety score is computed as the mean of the 7 items, with higher scores indicating greater perceived psychological safety within the team.
Time frame
Baseline (T0, pre-intervention; up to 5 minutes), Week 3 (T1; up to 5 minutes), and Week 6 (T2, post-intervention; up to 5 minutes)2
Peer Trust (HERO horizontal trust, 4-item team-referent measure)
Peer trust within the squad assessed using a 4-item team-referent horizontal trust measure drawn from the HERO organisational trust framework. Items are answered on a 0-6 response scale (strongly disagree to strongly agree). A composite peer trust score is computed as the mean of the 4 items, with higher values indicating greater perceived horizontal (peer) trust among teammates.
Time frame
Baseline (T0, pre-intervention; up to 5 minutes), Week 3 (T1; up to 5 minutes), and Week 6 (T2, post-intervention; up to 5 minutes)3
Team Identification (6-item team-referent identification scale)
Team identification assessed using a 6-item team-referent identification measure adapted from Mael \& Ashforth. Items are answered on a 1-7 Likert-type response format. A composite identification score is computed as the mean of the 6 items, with higher scores indicating stronger identification with the team.
Time frame
Baseline (T0, pre-intervention; up to 5 minutes), Week 3 (T1; up to 5 minutes), and Week 6 (T2, post-intervention; up to 5 minutes)Sponsors and contacts
