title: The role of emotion regulation in auditory hallucinations.
abstract: Emotion regulation involves the use of strategies to influence the experience and expression of emotions. Anxiety and depression are strongly associated with the positive symptoms of schizophrenia, such as auditory hallucinations (AHs). Individuals usually try to down-regulate (decrease) such emotions, consequently abnormal or maladaptive use of one or more of these down-regulatory processes (e.g. increased use of expressive suppression or maladaptive attentional deployment, i.e. rumination/worry) may play an important role in AHs (e.g. increasing AH severity and distress). This study examined the self-reported use of a range of emotion regulation strategies in individuals with schizophrenia and current AHs (SZ AH; N=34) and healthy controls (N=34). Two separable dimensions of hallucinatory experiences (severity and distress) were assessed together with measures of anxiety, depression and happiness. Within the SZ AH group, greater use of expressive suppression was associated with an increase in severity of AHs and greater disruption in daily life. In addition, rumination was significantly positively correlated with the distress (but not with the severity) associated with AHs. Within the control group, expressive suppression, rumination and worry were associated with more anxiety/depression and less happiness, as predicted. The implications of different emotion regulation strategies for the treatment of individuals with schizophrenia and AHs are discussed.
