Abstract

The purpose of the current study was to examine the way individuals with persecutory delusions construe the self, others, and their main persecutor with reference to the constructs of malevolence and omnipotence, and examine the extent to which these interpersonal beliefs link to distress, self-esteem, and delusion conviction. Repertory grid methodology was used to explore interpersonal beliefs about malevolence and omnipotence in a sample (N = 30) of individuals with current persecutory delusions (mean age 36.4 years; 62% male and 53% White). Participants also completed measures of emotional distress (depression and anxiety) and self-esteem. The findings suggested that persecutors were construed as more omnipotent and malevolent than both the self and others; others in turn were construed as more omnipotent and malevolent than the self. Beliefs about self as powerful were associated with lower anxiety, depression, and higher self-esteem, and beliefs about persecutors’ omnipotence predicted delusion conviction. As with voices, the concepts of power/omnipotence and malevolence/benevolence appear to be important constructs when seeking to understand the relationship between individuals and their perceived persecutors. These findings support working therapeutically with negative schematic beliefs about self, others, and persecutors, which is consistent with a person-based cognitive therapy model of distressing psychosis.
