This document summarizes a study that investigated the language used by 14-year-old students in England to describe people with mental illness. The researchers found that 400 out of 472 students provided 250 negative words and phrases. The words were grouped into five themes: 1) popular derogatory terms which accounted for nearly half the words, 2) negative emotional states, 3) confusion between mental illness and physical/learning disabilities, 4) limited use of psychiatric diagnoses, and 5) unexpected low reference to violence. The findings suggest that interventions are needed to address the students' lack of factual knowledge about mental illness and reduce their strong negative reactions.
