Trust in Dyads.
| SUBTHEME | ILLUSTRATIVE QUOTE | DYAD |
|---|---|---|
| Trust as foundation | “Not that I don’t trust other people, it’s just you don’t know them, and I think, knowing people and them knowing a little bit about you, you know who they are, and you’re comfortable. That’s what is really beneficial in terms of a great-working relationship.” | Midwife and Obstetrician 1 |
| Psychological safety | “I know that [John] trusts my judgment. If I didn’t trust [John], I wouldn’t be able to go to him and feel psychologically safe in saying what my feelings are, because I’m just a nurse to some people.” | Emergency Nurse and Emergency Physician |
| Fragility vs abundance of trust | “Because if you can’t trust the other person, then you’re not part of a team. You have two people working and you’re doing your job and second guessing their job.” | Ophthalmologist and Anaesthetist.1. |

| Transparency | “He is able to speak out loud all of his thoughts, and because he says what is happening, everyone is able to talk out loud.” | Anaesthetist and Anaesthetic Nurse |
| Levity/humour | “We’ll text each other stupid memes; it doesn’t break the flow, but it just sort of resets us.” | Obstetrician and Emergency Physician |

Table 8
Analysis of Patterns Stemming from Dyadic Experience.
| RELATIONSHIP/PATTERN | ANALYSIS | CAVEAT/POTENTIAL CONFOUND |
|---|---|---|
| When there was greater dyad familiarity, there was a higher shared volume of work and more explicit physical and gestural cues were deployed. | In dyads that had worked many years or many procedures together (e.g. >100), there was more mention of subtle gestural coordination (eye cues, small gestures) than in dyads with shorter tenure. | This could be a visibility bias. For example; when people know each other well, they notice these cues. |
| When there was more experience, (such as years in a role) there was more talk about emotional regulation and calmness. | Older, more senior participants more often spoke of staying calm, hiding emotion, or co-regulating under pressure. | Senior clinicians might also feel more able to articulate these emotions, so reporting bias might play a role. |
| Dyads with a strong learning culture (simulation, debriefs) tend to also emphasize psychological safety. | Where debriefs, feedback, and structured learning were strong, participants more often spoke about being safe to speak up, making mistakes, or emotional processing. | It may be that the same relational qualities (trust, openness) grow when there is more experience together, ensuring more psychological safety. |
| In dyads with more cross-discipline overlap (e.g. surgeon and anaesthetist) there was stronger talk of shared mental models, planning, and decision alignment. | In surgical/anaesthesia dyads, participants often mentioned stress pre-case, and so planned alignment, intra-case updates, and spoke of adapting together. | These dyads may inherently require more coordination, so the theme is situationally more visible. |

The Collaborative Practices Table; Relational vs Cognitive Behaviours and Attitudes.
| COLLABORATIVE PRACTICES TABLE — RELATIONAL VS COGNITIVE | |||
|---|---|---|---|
| PRACTICE/STRATEGY | RELATIONAL (INTERPERSONAL, AFFECTIVE) | COGNITIVE/STRATEGIC (THINKING, COORDINATION) | SAMPLE INDICATORS/NOTES |
| Trust | vulnerability, reliability, moral alignment | predictability, transparency, consistency | Many dyads said “I trust that she’ll do X”; trust developed over time. |
| Connectedness/Rapport | banter, personal stories, empathy, checking in | Dyads often “like each other,” share non-clinical chat. | |
| Shared Mental Models/Pre-planning | aligning mental models, “what if” scenarios, defining endpoints | Pre-briefs, discussing a plan before the case starts. | |
| Situation Awareness | reading partner cues, attention to environment | anticipating changes, scanning for cues, updating the mental model | Nonverbal cueing, mid-case updates, coordinate and adaptation. |
| Physical Communication | eye contact, posture shifts, touch, gestures | using gestural cues to coordinate timing, signalling | Gestures, shoulder taps, glance cues, spatial orientation |
| Reflexivity Reflection/Debriefing/Feedback | safe voice, open discussion, emotional processing | micro-analysis, “what went well/what not,” feedback loops | Many dyads do after-action reviews and informal post-case talk. |
| Boundary Norms/Conflict Avoidance | norms about not criticizing publicly, respectful tone | rules about where/when disagreement is aired | “We don’t disagree in front of the patient,” private resolution |
| Emotional Regulation/Co-regulation | calming presence, managing partner’s emotional state | maintaining focus under stress, regulating cognitive load | Dyads mention staying calm, mutual support when tense |
| Role Clarification/Complementarity | recognizing each other’s domain, respecting autonomy | distributing tasks, determining who leads in which domain | “She handles X, I handle Y,” seamless role handoffs |
| Learning Practices (Simulation, Checklists) | shared humility, joint improvement | structured tools, checklists, simulation, measurement | Use of simulation, checklists, experimenting, adopting new methods |
| Conflict Management/Tension Resolution | Airing disagreement respectfully and repairing relational strain | Negotiation, boundary enforcement, feedback timing | Some dyads mention “heated discussion” and always with resolution discussion |

Positioning the Expert Dyad Framework within contemporary teamwork literature.
| FRAMEWORK | CORE FOCUS | STRENGTHS | LIMITATIONS/GAPS | EXPERT DYAD FRAMEWORK MICRO-PRACTICES |
|---|---|---|---|---|
| Big Five Teamwork (Salas, Sims & Burke, 2005) | Five core teamwork processes (team leadership; mutual performance monitoring; backup behaviour; adaptability; team orientation) supported by coordinating mechanisms (shared mental models; closed-loop communication; mutual trust) | High theoretical grounding; serves as a clear, parsimonious framework for team effectiveness across contexts; widely cited in the teamwork literature | Operates at team level rather than fine-grain dyadic micro-interaction; lacks direct focus on physical signalling, glance/gesture, micro-relational calibration in pairs | EDF complements this by specifying micro-practices like gestural cueing, relational calibration, emotional atunement, subtle boundary signalling between two interacting individuals |
| TeamSTEPPS King H, Battles J, Baker DP, Alonso A, Salas E, Webster J, Toomey L, Salisbury M. TeamSTEPPS™: Team Strategies and Tools to Enhance Performance and Patient Safety. Rockville, MD: Agency for Healthcare Research and Quality; 2006. | Standardized teamwork skills: communication, leadership, situation monitoring, mutual support, role clarity | Widely adopted; provides practical tools and training modules | Treats dyads as mini teams without specifying micro-coordination; limited focus on relational calibration or non-verbal signalling | Specifies gestural cueing, relational calibration, emotional atunement, boundary norms for disagreement and micro-adjustments mid-interaction. |
| Team FIRST Greilich PE, Kilcullen M, Paquette S, Lazzara EH, Scielzo S, Hernandez J, et al. Team FIRST framework: Identifying core teamwork competencies critical to interprofessional healthcare curricula. J Clin Transl Sci. 2023;7(1):e106. | 10 teamwork competencies: recognizing teamwork, psychological safety, structured communication, closed loop, clarifying questions, sharing unique info, optimizing mental models, mutual trust, mutual performance monitoring, reflection/debriefing | Strong, evidence-based, tailored to healthcare; emphasis on interprofessional curricula | Operates at team level; less attention to how two individuals dynamically coordinate via gesture, glance, emotional regulation | EDF shows how Team FIRST competencies are embodied in dyads—e.g. how “structured communication” becomes gaze shifts or minimal cues; how “mental model alignment” becomes micro calibration and checking |
| Frontiers Healthcare Team Effectiveness Framework Zajac S, Woods A, Tannenbaum S, Salas E, Holladay CL. Overcoming Challenges to Teamwork in Healthcare: A Team Effectiveness Framework and Evidence-Based Guidance. Front Commun. 2021; 6:606445. | Broad challenges to teamwork in healthcare: accountability, conflict, decision making, reflection, communications, context (from qualitative + survey data) | Useful at system/team levels; identifies common barriers and enabling strategies | Doesn’ zoom into micro pair interaction; conflict and relational drift under-specified | EDF brings forward relational repair, micro-conflict norms, co-regulation under stress, and fine grain relational gestures |
| Relational Coordination/Relational Perspectives Gittell JH, Godfrey M, Thistlethwaite J. Interprofessional collaborative practice and relational coordination: Improving healthcare through relationships. Journal of Interprofessional Care. 2013;27(3):210–3. | Emphasis on work coordination via relationships: shared goals, shared knowledge, mutual respect, frequently timely communication | Excellent for linking relational and structural coordination at team/organizational levels | Less emphasis on how individuals enact relational coordination in minute-by-minute interaction | EDF shows how relational coordination is embodied: through glance cues, touch, micro reflection, mutual atunement in dyads |
| Dyadic Leadership/Dyad partnership models Clouser JM, Vundi NL, Cowley AM, Cook C, Williams MV, McIntosh M, Li J. Evaluating the clinical dyad leadership model: a narrative review. J Health Organ Manag. 2020;34(7):725–741 | Role alignment, shared vision, trust, communication in leader–co-leader dyads (mostly administrative/strategic) | Focuses on pair relationships, role negotiation, trust | Usually distant from clinical micro-interaction, limited in capturing split-second cueing or emotional regulation in high pressure | EDF brings micro-relational responsiveness, calibration under pressure, feedback loops between two people, and micro experiential reflection in clinical dyads |
