Abstract
We conducted Goldberg's 30-item General Health Questionnaire (GHQ) on 1,216 Japanese general population aged 40-92. Among them, 9.8% of males and 13.7% of females scored over the cut-off point which is used to indicate minor psychiatric disorders. Factor analysis was carried out using the Likert method and eight factors labelled as follows were selected: depression, anxiety and tension, anergia, interpersonal dysfunction, difficulty in coping, insomnia, anhedonia and social avoidance. The mean value of the standardized scores for each age-sex group indicated that changes in sex-age social roles with age affect the mental health of the general population.
