About this study
Official title: Brief Structured Team Reflection Embedded in Elite Underwater Rugby Training: A Three-Wave Field Evaluation of Cohesion, Psychological Safety, Peer Trust, and Team Identification
This single-arm field evaluation examined whether a brief, structured team reflection routine embedded within usual elite underwater rugby training was associated with change in team cohesion, psychological safety, peer trust, and team identification across three measurement occasions. Twenty-five male athletes contributed at least one assessment. Baseline responses were recorded on 16-17 February 2026 (T0), midpoint responses after session 6 on 5-9 March 2026 (T1), and endpoint responses after session 12 on 18 March 2026 (T2). The registered plan anticipated 16 sessions over six weeks; operational delivery concluded after 12 sessions, and no later follow-up was conducted.
Read the detailed description
The intervention consisted of brief, structured team-reflection conversations embedded within the squad's usual training environment. The routine used concise prompts, turn-taking, and a 'share-only' rule that prohibited interruption, rebuttal, blame, selection discussion, and cross-talk.. Sessions were intended to close with an observable cue, rule, norm, or micro-habit for subsequent training.
The registered plan anticipated 16 sessions over six weeks. Operational delivery concluded after 12 sessions. Assessments were completed at T0 (16-17 February 2026), T1 after session 6 (5-9 March 2026), and T2 after session 12 (18 March 2026). No later follow-up was conducted.
The retained study file contains outcome responses but no complete nominal record of attendance, actual session duration, facilitator fidelity, protocol deviations, training availability, injury, or illness. Accordingly, no attendance percentage, fidelity percentage, dose-response analysis, or injury/availability result is claimed. Objective sport-performance outcomes were not collected.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Brief Structured Team Reflection (BSTR)Behavioural
Twelve brief, structured team-reflection sessions were embedded within usual elite underwater rugby training. Athletes responded to concise prompts in turn under a 'share-only' rule that prohibited interruption, rebuttal, blame, selection discussion, and cross-talk. Sessions normally closed with an observable cue, rule, norm, or micro-habit for the next training experience. The registered plan anticipated 16 sessions; operational delivery concluded after session 12.
| Study group | Role | What they receive |
|---|---|---|
| Usual elite underwater rugby training plus BSTR | Experimental | Participants continued usual elite underwater rugby training and took part in 12 embedded Brief Structured Team Reflection sessions. There was no separate control arm. Receives: Behavioral: Brief Structured Team Reflection (BSTR) |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Baseline 16-17 February 2026 (T0, pre-intervention; up to 5 minutes); T1: 5-9 March 2026 (after session 6; T1; up to 5 minutes) and T2: 18 March 2026 (after session 12; post-intervention; up to 5 minutes)
Secondary outcomes (3)
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.
Measured: Baseline 16-17 February 2026 (T0, pre-intervention; up to 5 minutes); T1: 5-9 March 2026 (after session 6; T1; up to 5 minutes) and T2: 18 March 2026 (after session 12; post-intervention; up to 5 minutes)
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.
Measured: Baseline 16-17 February 2026 (T0, pre-intervention; up to 5 minutes); T1: 5-9 March 2026 (after session 6; T1; up to 5 minutes) and T2: 18 March 2026 (after session 12; post-intervention; up to 5 minutes)
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.
Measured: Baseline 16-17 February 2026 (T0, pre-intervention; up to 5 minutes); T1: 5-9 March 2026 (after session 6; T1; up to 5 minutes) and T2: 18 March 2026 (after session 12; post-intervention; up to 5 minutes)

- No: Individual participant data (IPD) will not be shared publicly. The sample is small and drawn from a single, identifiable elite underwater rugby squad, so even de-identified records could carry a meaningful risk of re-identification when combined with contextual information (e.g., roster composition, training attendance patterns, and time-point assessments). Participant consent covers analysis and publication of aggregated results rather than unrestricted public release of participant-level data. Summary statistics and full methodological details will be reported in publications. De-identified extracts or additional details may be considered on a case-by-case basis, subject to a data-use agreement, ethics approval, and safeguards that minimise re-identification risk.
