Abstract

The present study investigated compartmentalization and self-complexity of self-structure in people with a history of bipolar disorder. Remitted bipolar, recovered depressed and healthy control participants described aspects of themselves using experimenter-provided positive and negative traits. Compartmentalization was assessed by the partitioning of positive and negative traits between self-aspects. Complexity was assessed by both the number of self-aspects people generated and the degree of overlap between the self-aspects. The remitted bipolar and recovered depressed groups demonstrated greater compartmentalization than healthy controls and the remitted bipolar group also demonstrated greater self-complexity than healthy controls when self-aspects relating to the depressed and manic states were included. Compartmentalization may be a generic feature of mood disorder. In addition, bipolar disorder is characterized by a complex, differentiated self-concept with distinctive beliefs about the self in depressed and manic states. Therapeutic implications are discussed.

From the overall ratio of positive and negative words chosen across the whole sort, expected frequencies of positive and negative words within each self-aspect can be computed. As these represent chance values, Cramer’s V can then be used to assess the deviation from a random sort. Cramer’s V ranges from 0 to 1, with 0 representing a wholly random sort and 1 representing a perfectly compartmentalized sort.

Overlap is computed as follows:

$$ OL = (\Sigma _i \Sigma _j C_{ij} )/T_i )/n*(n - 1) $$

C relates to the number of common features in 2 aspects, T the total number of features in the referent self-aspect and n refers to the total number of aspects within the individual’s sort. OL is derived by first computing the pair-wise communality between the referent aspect and all other aspects in terms of the proportion of traits in common, within the total number of traits in the referent aspect. As pair-wise comparisons are conducted between all combinations of two groups, each aspect becomes the referent aspect. The mean of all proportions of pair-wise comparisons is then computed to provide an index of OL. In the present study, OL was computed for each participant across all aspects and subsequent to the ‘illness’ self-aspects being omitted in the two mood-disorder groups.
