Research suggests that self-esteem is influential in many aspects of schizophrenia, including symptomatology, experience ofillness, quality of life, and recovery (Barrowclough, et aI, 2003; Freeman, et aI, 1998). However, this field of study has been limited by a number of factors including a lack of longitudinal research, difficulties in interpreting the construct, and problematic measurement techniques (Andrews & Brown 19903). Barrowclough et al. (2003) used an interview-based method ofself-esteem assessment (SESS-sv), which was found to be superior to past measures ofthe construct. Using this measure, Barrowclough and colleagues (2003) found a relationship between negative self-evaluation and positive symptom severity and an inverse relationship between positive self-evaluation and negative symptoms. The general aim ofthe current research is to investigate the relationship of self-esteem to aspects ofpsychopathology in a clinical and a non-clinical sample, using new measures that address past inconsistencies in the self-esteem literature. Method The relationship between self-esteem and psychopathology was assessed in three ways: (1) A follow-up investigation ofBarrowclough and colleagues (2003) study was conducted to address the stability ofself-esteem and its effect on outcomes over time; (2) A new self-report measure of self-evaluation was developed based on an established interview to see if the benefits of the SESS-sv are due to its interview format or to its specific conceptualization ofthe construct; (3) The psychometric properties ofthe measure and its relation~hip to positive and negative symptoms of psychosis were tested in a clinical and a non clinical sample. Results Self-evaluation appeared to be relatively stable at follow-up. Time to relapse was associated with High negative self-evaluation and inversely with High positive selfevaluation. The Questionnaire for Evaluation of Self (QES) was found to be a reliable and valid self-report assessment of self-evaluation. As predicted, negative selfevaluation was strongly associated with positive symptoms ofpsychosis, specifically feelings ofparanoia and persecution. Participants in the clinical sample had greater levels ofnegative self-evaluation than a university sample, but their levels ofpositive self-evaluation were comparable. Discussion/Conclusions This research emphasizes the importance ofrecognising the multi-dimensional nature of self-esteem and its potential long-term impact on outcomes. The QES is a useful new measure of self-evaluation that will be appropriate for use in both research and practice settings, as it provides a more comprehensive assessment of self-evaiuation than traditional self-report measures.
