Abstract
Schema Therapy is an effective therapy form for treatment-resistant depression. However, it remains unclear what cognitive schemas exactly are and how they function and influence other factors like negative mood in daily life. Based on several studies, there is a possibility that people with a negatively biased memory are more prone to activate dysfunctional schemas elicited by a life event, which may cause rumination and a negative mood state. Therefore, an observational, longitudinal ESM study was conducted on students from Radboud University Nijmegen (N = 90), to answer the following research questions: “Is cognitive schema activation associated with negative mood in daily life?”, “Is the association between schema activation and negative mood mediated by rumination?” and “Is the association between schema activation and mood state and schema activation and rumination moderated by pre-existing negative memory bias?”. During the baseline appointment on day 1, a computer task (SRET) was used to measure memory bias for negative words. During days 2-7, participants received on their smartphones 5 randomized prompts between 8:00 a.m. and 8:00 p.m., to measure schema-activation, mood, and rumination in daily life. A simple regression and moderated-mediation analysis was performed in the SPSS PROCESS macro. The current study indicates that schemas, which are characterized by negatively biased thoughts, were associated with negative mood, but most of this effect was explained by the repetitive focus on these negatively biased thoughts themselves. Further research is needed regarding schema activation in daily life by means of multilevel regression analysis and regarding the possible moderating effect of pre-existing negative memory bias among depressed patients in a clinical setting. Future research should also consider whether sessions of positive CBM can help vulnerable people with depressive symptoms change their EMSs in more adaptive ways.
