This study explores cognitive differences in bipolar patients during stable periods to aid in accurate diagnosis and treatment. The findings indicate a connection between certain cognitive factors and a history of manic episodes. By identifying these markers, clinicians can better differentiate bipolar disorder from other conditions. The research involved administering a self-report questionnaire to patients experiencing euthymic periods and analyzing the responses in relation to their clinical history. Ultimately, cognitive markers may offer new targets for treatment and improve diagnostic precision in mental health care.

A Cognitive Factor Differentiates Bipolar Patients in a Mixed Clinical Sample Bradford C. Richards, Ph.D. Jeanne A. Czajka, Ph.D. Pamela J. Stanley, LPCC, ACT Jennifer A. Harrington, Ph.D. Meagan C. Parmley, Ph.D. Cognitive Behavioral Institute of Albuquerque
Our Interest Seeking greater clarity: Many of our patients are diagnosed as Bipolar by their prescribing psychiatrists, but do not appear to meet criteria Bipolar Disorder is clearly over-diagnosed in our community (Stewart & El-Mallakh, 2007) When we began this study, no measurable cognitive factors were known to distinguish bipolar patients from unipolar patients while euthymic
Our Interest Challenge and Opportunity Only 4 or 5 years ago, many experts believed that bipolar and unipolar patients could not be distinguished by cognitive factors unless the bipolar patients were manic If cognitive markers for Bipolar Disorder could be found during stable periods, these markers might help point to new targets for treatment
Quasi-experimental design Specific aims We theorized that there are stable cognitive factors in bipolar patients that are identifiable during euthymic states We hoped to find significant differences in the levels of some of these factors when comparing bipolar patients to a mixed clinical sample and to a sample of unipolar depressed patients. We hoped that these factors could be used to successfully discriminate bipolar patients from a mixed clinical sample and from unipolars
Method: Participants Actual clinical population in treatment at the Cognitive Behavioral Institute of Albuquerque N=33, 15 males (avg age=45), 18 females (avg age=43) Therapist’s diagnoses: Unipolar 14 9 Males, 5 Females Bipolar 8 4 Males, 4 Females, 7 with hx of hosp. OCD 2 1 Male, 1Female PTSD 2 0 Males, 2 Females GAD 1 0 Males, 1Female Borderline 2 0 Males, 2 Females Adjust. D/O 3 1 Male, 2 Females OCPD 1 0 Males, 1 Female
Method: Measures Preparing our exploratory measures We read Eisner, Johnson, & Carver’s (2008) finding that Upward Generalization items were associated with Hypomanic Personality in college students. We generated additional items based on speculation about Hyper-positivity (Lam, 2000), Risk-taking (Leahy, 2004), Action Predisposition, Self-Proof, and Self-Redemption We attempted to craft items reflecting adequate levels of social desirability

My actions speak louder than my words. Because people have told me that I’m smart, I know I can earn people’s respect in anything I do. Virtue should be its own reward. I am able to do things with more energy than most people. If people underestimate me, it’s up to me to show them what I can do. Every task I do is an opportunity to prove what kind of person I am.

Therapist’s concurrent ratings (blind) History of all DSM-IV Bipolar Disorder symptoms, each rated for severity by therapist on a scale of 1-7 Number of hospitalizations for manic, non-depressed states Therapist’s overall impression of patient’s chronic bipolar tendency severity Therapist’s rating of patient’s current arousal state: (Comatose) 1 2 3 4 5 6 7 (Extremely excited) Therapist’s rating of patient’s current level of depression (Not at all depressed) 1 2 3 4 5 6 7 (Severely depressed)
Procedure Therapists (n=4) were instructed to administer the 10-item self-report questionnaire to all of their most clear-cut and severe cases of Bipolar Disorder, along with a mixture of other non-Bipolar patients Therapists were instructed to administer the questionnaires and make their own ratings only while patients were experiencing euthymic periods, not while patients were experiencing any manic, hypomanic, or depressive symptoms Therapists remained blind to their patients’ responses throughout the course of the study
Preliminary Analyses Therapist ratings of overall Bipolar Tendency had no associations with any of the clients’ responses to the ten questions, all ps > .05 Therapist ratings of specific symptoms had no associations with any of the clients’ responses, all ps > .05 The best differentiator of clients’ responses turned out to be a history of hospitalization for mania. Patients with any history of hospitalization for maniashowed significantly elevated responses on 3 of the ten questions, ps < .05

Conclusions The notion that Unipolar and Bipolar patients are indistinguishable while euthymic is strongly contradictedby the present results – they were highly discriminable, with correct classifications 81% - 100% of the time. Replication of Eisner, Johnson, & Carver’s (2008) association of hypomanic personalities with upward generalization tendencies supports theories based on Behavioral Approach System Sensitivity (Alloy et al., 2009)
Conclusions Our discriminative items support new theorizing by Mansell et al. (2009) about self-perceptions and appraisals of mood states in bipolar disorder. The hypothesized importance of the “strong personal meanings” of Action and Energy are supported by the present findings. The discrimination of Bipolar patients by their explicit Action Predisposition is a promising lead for future study.
Implications for psychotherapy It is not safe to conclude that the 3 discriminating items we found are merely psychologically inert scars of previous manic episodes. It is quite possible that excessive valuations of energy, excessive valuations of action, and excessive tendencies to upwardly generalize from rewards function as enduring latent cognitive vulnerabilities to mania. We owe it to our patients to explore these factors as possible ongoing vulnerabilities.
Implications for psychotherapy With regard to excesssive Upward Generalization, therapy targeting Moderation in Goal-Setting has already achieved some empirical support (Johnson & Fulford, 2009) Therapy for excessive valuation of energy and excessive valuation of action would require change at the level of core implicit values. Explicit Functional Analysis of Specific Emotional Responses may help patients see the potential value in tolerating Low-energy, Inactive states. As far as we know, therapy aimed at enhancing tolerance for passivity and disinterest has never been systematically studied.
Implications for psychotherapy Therapy aimed at increasing Action could actually reinforce a cognitive vulnerability to Bipolar Disorder An alternative therapeutic target for functional analysis might be Increasing Reflection rather than Action Reflection may be usefully directed to: Understanding the Meanings of low-energy, low-activity states The Utilityof inactive, low-energy “decompression” Reducing Aversion to low energy states Finding Self-efficacy in low-activity states Noticing increases in Personal Reliability as low-energy, low-activity states become valued (e.g., ability to listen)
