Which open-ended question is most suitable for a client in the contemplation stage of change?

The most suitable open-ended question for a client in the contemplation stage of change is one that encourages reflection on the implications of making a change without pushing for an immediate commitment. The selected question prompts the client to evaluate both the positive aspects (pros) and the potential drawbacks (cons) of making a change at this moment. This stage is characterized by an awareness of the need to change but ambivalence about it, so exploring the pros and cons can help clients clarify their thoughts and feelings about the change, leading to deeper insights and a potential movement toward readiness for action.

In contrast, the other questions either push the client to think about change in a more immediate or directive way or address past experiences without focusing on the present contemplation stage. The focus on pros and cons specifically helps the client evaluate their current situation and consider their options, making it particularly pertinent for someone who is weighing the decision of whether or not to change.
