In general, studies have shown that the Attributional Style Questionnaire has extremely poor psychometric properties and, in particular, that scores on individual items show poor consistency. It has continued to be the most widely used attributional measure mainly because of the lack of aviable alternative.

Hove: Lawrence Erlbaum, pp. 337–60; R. P. Bentall, P. Kinderman and S.

Wykes (eds.), Outcome and Innovation in the Psychological Treatment of Schizophrenia. Chicheste
r: Wiley, pp. 119–44.

  5. The assumption that delusions reflect attempts to explain troubling experiences is apparent, for example, in Brendan Maher’s anomalous perception theory, in Chris Frith and Rhiannon Corcoran’s ideas about the role of theory-of-mind deficits in persecutory delusions, in the work that Sue Kaney, Peter Kinderman and I have conducted on paranoia, and also in Philippa Garety and David Hemsley’s studies of the way in which deluded patients reason about hypotheses.

Another type of implicit self-measure, based on the self-referent encoding effect, was used in this study but produced more equivocal results. For simplicity, I have not described it in the main text.
