The development of the material in this study is considered for use in exploring cognitive styles in bipolar disorder using experimental methodology to investigate information-processing biases related to internal states. Design/Method: The study used a cross-sectional design based on a student sample recruited from the University of Edinburgh. A list of 36 internal state words were selected and matched with 36 neutral words, for length and frequency of occurrence in the English language. A sample of 86 students from the university of Edinburgh were asked to rate the list of 72 words on a 7 point likert-type scale for level relating to internal state, emotional state and self-relevance (e.g. not at all internal to extremely internal). Participants also completed three standardised measures assessing, depression, mania/hypomania and anxiety. Results: Data was analysed using SPSS 16.0 for windows. Descriptive statistics identified 10 words meeting criteria for highly internal, low emotional matched with 10 neutral words, meeting criteria for low ratings on internal and emotional scales. An additional list of 14 internal-emotional words were generated also matched with neutral words meeting specified criteria. Self-relevance ratings for these words were correlated using a series of correlational analysis (Spearman’s rho) with scores on the standardised measures. Significant results were observed between most of the words and measures of mania/hypomania and depression, for internal and neutral words. Conclusions: Primary findings support the development of a list of highly internal, not confounded by emotion, words, matched with neutral words for use in future research. Using self-relevance ratings to carry out preliminary investigation of the validity of these words and preliminary investigate hypotheses inferred from Mansell et al (2007) model, show inconclusive results. The clinical and theoretical implications of the study and particularly the use of this developed material for use in future research are discussed.
