A method for the study of lay conceptions of psychopathology: a free-response approach

A free-response approach for identifying a lay group's conception of psycopathology is described in this paper and is illustrated with a college student population. An initial sample of individuals from the population is asked to give "reasons why someone might need to be examined by a professional person in the field of mental health." A second sample of individuals sort the problem statements on the basis of their judgements of the similarity among the statements. A measure of psychological distance for each pair of statements, based on the proportion of times the two statements are sorted together, is used as input for clustering and multidimensional scaling. A third sample contributes to the interpretation of the resulting structures by rating each problem on several psychological properties. The most relevant properties found for college students are: (a) degree of abnormality; (b) referral source--self versus others. Also disc1ssed are possible applications of the method to other lay groups in the interest of providing improved community mental health services to such groups.
