Final answer:
Choosing not to collect health risk assessment data before coaching sessions may lead coaches to use an 'expert hat' approach, possibly curtailing personalized client guidance.
Step-by-step explanation:
When a coach decides not to collect health risk assessment data or personal wellness information prior to the first session, some coaches do this because it may increase the likelihood that the coach uses the "expert hat". This approach might influence the coaching process, steering the coach to deploy a more authoritative or prescriptive style based on their own expertise rather than facilitating a client-centered dialogue. Without the health risk assessment data, coaches might aim to rely on general experience rather than specific client details which can curtail personalized guidance and rapport-building that comes from understanding a client's unique health background.
