Final answer:
For the second training session using the scaffolding approach, the OT should encourage the client to pay for the bus fare and recognize the destination stop themselves, with the OT providing verbal guidance and feedback instead of direct demonstration.
Step-by-step explanation:
When an individual with chronic mental illness is learning to take a bus using the scaffolding approach, the occupational therapist (OT) should gradually reduce the level of assistance provided in subsequent training sessions to promote independence. In the next training session, instead of demonstrating and walking with the client throughout the process, the OT might suggest the client try to pay for the bus themselves while still under supervision, and then verbally guide them on when to get off the bus, rather than pointing it out. The ultimate goal would be for the client to perform these tasks independently, with the OT only observing and providing feedback as necessary.
