The coach's reply, “Something has changed since we last talked,” is an example of complex reflection because it not only reflects content but also implies understanding of the client's experience and emotional state. Complex reflections deepen the conversation by interpreting the underlying meaning and acknowledging the shifts or developments the client is experiencing. This response signals to the client that the coach is actively engaged in the dialogue and is attuned to the nuances of their journey, encouraging further exploration.

In contrast, simple reflections might merely restate what the client has said without adding any interpretation or deeper insight. Affirmations serve to reinforce and support the client by acknowledging positive qualities or efforts they have made, while open-ended questions invite the client to share more information or explore topics in greater depth. Each of these techniques serves unique purposes in coaching interactions, but the reply in question transcends mere reflection by recognizing and validating changes in the client's experience, cementing it as a complex reflection.
