Arthur has been referred for a clinical assessment. He strongly believes he is a medieval knight. He frequently wears a heavy suit of replica chainmail armor and insists on speaking in Middle English to his landlord, which has caused severe friction between them.
Because of his refusal to use computers or telephones at work, which he describes as "unholy machinery," Arthur was dismissed from his administrative role. As a result, he is falling behind on his rent and can no longer afford his hobbies or proper groceries.
Recently, while walking down a busy street, Arthur believed a passing delivery van was a hostile charging beast. He drew a wooden souvenir sword to defend himself, stumbled off the curb into oncoming traffic, and was clipped by a cyclist, resulting in a fractured wrist and a visit to the hospital. When interviewed by a clinical psychologist, Arthur expressed that he feels a profound sense of honor and peace when acting as a knight. However, when he considers his mounting debts and his strained relationship with his family, he admits to feeling deeply overwhelmed, hopeless, and miserable.
To what extent are deviance, dysfunction, distress and danger useful in diagnosing Arthur with a mental health disorder?
