Extract

The Purpose of the Present Investigation

In their study “The relation between neurosis and psychosis: an analysis of symptoms and past history of 819 psychotics and neurotics”, Trouton and Maxwell (1956) were the first to apply the statistical technique of factor analysis to the isolation of clinical items representing the independent dimensions of ‘psychoticism’ and ‘neuroticism’. The findings were subsequently exploited for diagnostic purposes by other investigators (e.g. Richmond and Roberts, 1964), and the study and its results extensively quoted by Eysenck (1961) in his provocative review and critique of psychiatric classification to illustrate and lend support to his dimensional approach to psychiatric taxonomy.
