Why psychiatrists prefer to use mental disorder while psychologists prefer to use psychological disorder?

Psychiatrists often use the term "mental disorder" to align with medical terminology and emphasize the biological and neurological aspects of these conditions, which can be relevant for diagnosis and treatment. In contrast, psychologists tend to prefer "psychological disorder" as it highlights the cognitive, emotional, and behavioral dimensions of these conditions, reflecting their focus on therapy and psychological interventions. This distinction also underscores the different professional approaches and training backgrounds of each discipline.
