Cognitive correlates of mania risk: are responses to success, positive moods, and manic symptoms distinct or overlapping?
Several measures of cognitive style have been shown to be elevated among persons diagnosed with bipolar disorder and those at risk for bipolar disorder. Several of these scales capture responses to positive affect, success, and hypomanic symptoms. We had two goals: (a) to use factor analyses to assess whether the constructs within these scales were statistically independent and (b) to examine whether the factors identified uniquely related to mania risk. A cross-national sample of 638 participants completed measures of cognitive style, including the Responses to Positive Affect scale, the Positive Overgeneralization Scale, and the Hypomanic Interpretations Questionnaire. To assess whether these measures might simply reflect more impulsive reactions to positive mood states, participants also completed the Barratt Impulsivity Scale. To measure risk of mania, participants completed the Hypomanic Personality Scale (HPS). Factor analyses suggested seven factors of cognitive style and impulsivity. Four factors uniquely correlated with HPS. That is, risk for mania related to higher scores on separable factors of acting before thinking, being overly positive in interpreting manic symptoms, being overly confident in response to success, and tendencies to dampen positive affect. Current findings suggest the need to consider multifaceted aspects of cognition in refining psychological treatments of bipolar disorder.
