Final answer:
A cognitive-behavior therapist is least likely to be successful in helping Jan, who believes that she is being followed by people from another planet.
Step-by-step explanation:
A cognitive-behavior therapist is least likely to be successful in helping Jan, who believes that she is being followed by people from another planet. This is because Jan is likely experiencing delusions, which are fixed and false beliefs that are not based in reality. Cognitive-behavior therapy focuses on changing thoughts and behaviors based on rational thinking, which may not be effective in addressing delusions.
On the other hand, cognitive-behavior therapy can be helpful for clients like Jordan, who has anxiety about home safety and engages in repetitive behaviors to alleviate his anxiety. This therapy can address his irrational thoughts and behaviors by challenging and changing them. It can also be effective for clients like Jouma, who has social anxiety and avoidance due to fear of negative judgment. Cognitive-behavior therapy can help Jouma challenge and change her negative thoughts about being judged and gradually engage in social situations.
For clients like Jenkins, who are depressed and have negative beliefs about themselves, cognitive-behavior therapy can also be effective. This therapy can help him identify and challenge negative thoughts, develop healthier beliefs, and engage in activities that improve mood and self-worth.
