Final answer:
The appropriate action to institute consequences for manipulative behavior is to set clear boundaries and consequences. This method aligns with cognitive-behavioral therapy, which takes thoughts and actions into account in treatment.
Step-by-step explanation:
To address manipulative behavior, the correct approach is to set clear boundaries and consequences. This strategy aligns with cognitive-behavioral therapy principles where cognitive processes and behaviors are considered.
By setting boundaries, you communicate what is acceptable and what is not, while consequences provide a tangible deterrent against the repetition of manipulative behavior.
This approach is significantly more effective in promoting behavioral change than reinforcing or ignoring the behavior or immediately referring to another therapist without attempting intervention.
