Schizophrenia and bipolar disorder have been associated with shared and distinct emotion processing abnormalities. Initial findings indicate that these disorders differ with respect to the domain of emotional intelligence (EI). Individuals with schizophrenia display deficits on performance measures of EI, whereas those with bipolar disorder do not. However, no research has examined patients' subjective beliefs about their own EI (referred to as “perceived EI”). This study examined perceived EI, assessed with the Trait Meta-Mood Scale (TMMS), and its clinical and functional correlates in outpatients with schizophrenia (n = 35) or bipolar disorder I (n = 38) and matched healthy controls (n = 35). The TMMS includes three subscales that assess beliefs about one's ability to attend to (Attention to Feelings), understand (Clarity of Feelings), and repair emotions (Mood Repair). Participants in the clinical groups also completed community functioning and symptom assessments. Both clinical groups reported significantly lower perceived EI than controls, but did not differ from each other. Higher total TMMS correlated with higher levels of independent living in the schizophrenia group (r = .36) and better social functioning in the bipolar group (r = .61). In addition, although higher Attention to Feelings scores correlated with greater psychiatric symptoms in the schizophrenia group, higher scores across all subscales correlated with less manic symptoms in the bipolar group. The findings suggest that perceived EI is impaired and related to community functioning in both disorders.
Research from an affective science perspective has begun to specify differences and similarities in the emotion processing abnormalities associated with schizophrenia and bipolar disorder. On one hand, these disorders are associated with different patterns of in-the-moment responses to emotionally evocative stimuli. While schizophrenia patients demonstrate normal emotional responses to evocative stimuli (Kring and Elis, 2013), bipolar patients demonstrate prolonged positive emotion during emotion-eliciting laboratory tasks (Gruber, 2011). However, both clinical groups show deficits in emotion regulation, including difficulty modulating neural responses to unpleasant stimuli through cognitive reappraisal in schizophrenia (Horan et al., 2013) and, in bipolar disorder, using more emotion regulation strategies, but with less success, than healthy people (Gruber et al., 2012). Examining other aspects of emotion processing can further illuminate differences and similarities across these disorders. For example, an aspect of emotion processing that has received research attention in major mental illness is emotional intelligence (EI). Mayer et al. (2008) define EI as the capacity to process one's own and others' emotions (i.e. perceive, access, generate, and reflectively regulate emotions) to guide thinking about behavior. Accordingly, EI is viewed as a unique set of abilities that plays a critical role in adaptive socio-emotional functioning. To date, nearly all research on EI in mental illness has focused on performance-based measures, particularly the Mayer–Salovey–Caruso Emotional Intelligence Test (MSCEIT; Mayer et al., 2002). The MSCEIT assesses four “branches” of EI: emotion perception, using emotions, understanding, and managing emotions. Patients with schizophrenia demonstrate impairments on this measure across all four domains, and lower MSCEIT scores are related to greater positive and negative symptoms, low functional capacity, and poor functional outcome (Kee et al., 2009, Eack et al., 2010 and Lin et al., 2012). We are aware of only two studies that used the MSCEIT in bipolar disorder and both found that performance was normal (Burdick et al., 2011 and Lee et al., 2013). In addition to performance-based measures, affective scientists have assessed self-reported or “perceived EI.” While the MSCEIT measures one's ability to identify and understand emotions in oneself and others, perceived EI measures the meta-experience of emotion, or one's subjective beliefs about his or her emotional abilities. The most commonly-used measure of perceived EI is the Trait-Meta Mood Scale (TMMS; Salovey et al., 1995). It contains three subscales: (1) Attention to Feelings (Attention): the tendency to notice and value emotions; (2) Clarity of Feelings (Clarity): the tendency to experience and name feelings clearly; and (3) Mood Repair (Repair): one's belief in his or her ability to repair negative emotions by fostering positive feelings. In healthy samples, TMMS scores are not strongly related to performance-based measures, such as the MSCEIT (Mayer et al., 2004), yet both are associated with mental and physical health and better social functioning (Schutte et al., 2007). Studies have demonstrated incremental validity for TMMS for outcomes; in healthy individuals, the TMMS predicts subjective well-being and adaptive functioning above and beyond factors such as current mood state, personality traits, and general intelligence (Palmer et al., 2002, Extremera and Fernández-Berrocal, 2005 and Fernandez Berrocal and Extremera, 2008). Higher scores on Clarity and Repair are consistently associated with positive outcomes, such as greater life satisfaction, interpersonal satisfaction, and less social anxiety and depression (Palmer et al., 2002, Salovey et al., 2002 and Salguero et al., 2012). Higher scores on the third subscale, Attention, are sometimes associated with positive outcomes, such as empathy, self-esteem, and adaptive physiological responses to acute stress (Salovey et al., 2002), but have also been associated with greater anxiety and depression (Salovey et al., 1995 and Salguero et al., 2012). We are unaware of any studies of perceived EI in schizophrenia or bipolar disorder using the TMMS. Research has been conducted on concepts related to perceived EI, such as mindfulness and alexithymia (related to the Attention and Clarity subscales) and emotion regulation (related to Repair). Schizophrenia patients display low levels of dispositional mindfulness (Chadwick et al., 2008), while bipolar patients and healthy controls do not differ on mindfulness (Perich et al., 2011). Also, schizophrenia patients report increased alexithymia (van't Wout et al., 2007), which has been associated with increased positive (Serper and Berenbaum, 2008) and negative symptoms (van't Wout et al., 2007). Individuals with schizophrenia additionally report abnormal emotion regulation styles and show impairment on performance-based and neurophysiological tasks (Kee et al., 2009, Kimhy et al., 2012 and Horan et al., 2013). Although individuals with bipolar disorder also report abnormal emotion regulation styles (Gruber et al., 2012 and Wolkenstein et al., 2014), they do not consistently show impairments on performance-based assessments (Burdick et al., 2011, Lee et al., 2013 and Gruber et al., 2014). There were three objectives for the current study. The first was to compare levels of perceived EI across schizophrenia, bipolar, and control participants. Based on prior research, we expected schizophrenia patients to report lower scores on all TMMS subscales, but we did not have clear directional predictions for the bipolar group. The second objective was to examine the correlations among perceived EI, characteristic symptoms for the two disorders (positive and negative symptoms, mania, and depression), and community functioning within each clinical group. The third objective was to determine whether perceived EI accounted for unique variance in functional outcome for each clinical group, above and beyond any contribution of symptoms.
