Final answer:
Cognitive-behavioral therapies have been developed for panic disorder, depression, and obsessive-compulsive disorder but not extensively for schizophrenia, which often requires a combination of treatments including antipsychotic medication.
Step-by-step explanation:
Cognitive-behavioral therapies (CBT) have been developed for a variety of mental health conditions, including panic disorder, depression, and obsessive-compulsive disorder (OCD). These therapies involve identification and change of negative thought patterns and behaviors that can contribute to emotional distress and mental health disorders. While CBT has proven effective for many conditions, its development for schizophrenia is not as pronounced. Schizophrenia typically requires a more complex treatment approach, often including antipsychotic medications and various forms of psychotherapy, which may or may not include elements of CBT.
