Toby is a clinical psychologist who is reviewing the diagnosis of his new patient, Maya. Maya was previously diagnosed with generalized anxiety disorder by a GP using the ICD-11, but a private psychiatrist recently diagnosed her with obsessive-compulsive disorder using the DSM-5. Toby is concerned about the reliability of these diagnostic tools.
Explain whether Toby's concerns about the reliability of Maya's diagnoses are justified.
