- Emotional distress
What are the issues in engaging patients with psychological therapy?
List 6
- Disenchanted with medical care
- Suspicious of mental health services
- Beliefs that symptoms are caused by disease

Why?
Patients who had negative experiences with healthcare feel dismissed and disbelieved
Engaging MUS patients with psychological therapy may make them feel like their symptoms are not believed
Why?
If they see a clinical psychologist instead of an actual doctor, they may feel like their symptoms are not taken seriously
