One possible cause is the therapist's lack of training. If they haven't been properly educated in different therapeutic techniques and how to handle various mental health issues, it can lead to bad therapy.
Another reason is the therapist's own mental state. If they are going through personal issues, it can affect their ability to provide good therapy. They may be distracted or project their own problems onto the patient, especially when basing the therapy on a true story where there could be more room for misinterpretation.
To some extent. The story of Bad Therapy incorporates elements from real cases but also takes creative liberties to make it more engaging for the audience.
I don't have a specific 'bad therapy true story' at hand. But generally, in a bad therapy situation, there might be issues like the therapist being unprofessional. For example, not respecting the client's boundaries, constantly interrupting the client while they are sharing their problems.
In a 'bad therapy based on true story', perhaps the therapist had some personal biases. Say, if the patient was from a different cultural background. The therapist, instead of being open - minded and understanding, imposed their own cultural values on the patient during the therapy sessions. This made the patient feel unaccepted and misunderstood, and the therapy became ineffective and even harmful.
