Fear of self and obsessionality: Development and validation of the Fear of Self Questionnaire

• The current study describes the development of a new questionnaire measuring fear of self.
• The questionnaire showed strong relationships with obsessional symptoms.
• Results shed light on an important clinical characteristic of those with obsessions.

Obsessions – particularly those directly relating to causing harm – often contain or imply evaluative dimensions about the self, reflecting a fear as to who the person might be – or might become. Following from research indicating that such beliefs are relevant to OCD, and the wider literature in social psychology regarding ‘feared’ or ‘undesired’ self-guides, the current study describes the development and validation of a new questionnaire—the Fear of Self Questionnaire, in 8- and 20-item versions. The questionnaire was piloted in two non-clinical samples (n=258; n=292). Exploratory and confirmatory factor analyses supported the unidimensionality of the measure. The questionnaire showed a strong internal inconsistency, and good divergent and convergent validity, including strong relationships to obsessional symptoms and with other processes implicated in cognitive models of OCD (e.g. obsessive beliefs, inferential confusion). Implications are discussed.
