Abstract This research aims to evaluate the effectiveness of Schema Therapy on cognitive emotion regulation and Emotional Behavior Regulation in mothers with children with learning disabilities. Based on purpose the research was applied with a semi-experimental design with pre-test, and post-test. The statistical population of the study was mothers of children with learning disabilities in Tehran in the first six months of 1400. The sample consisted of 30 mothers who were selected as the final sample by purposive sampling method and were randomly divided into two groups of experiments and control (each Group 15 mothers). Cognitive Emotion Regulation Questionnaire by Garnefski and Kraaij (2002) and Emotional Behavior Regulation by Garnefski and Kraaij (2019) were used. The experimental group received eight sessions of mindfulness-based cognitive therapy and the control group received no therapy. The results of covariance analysis showed that the Perceived Stress and Emotional Behavior Regulation was significantly different in the experimental group (P0.01). So Schema Therapy can be used effectively on cognitive emotion regulation and Emotional Behavior Regulation in mothers with children with learning disabilities. Keywords: Schema Therapy, Cognitive Emotion Regulation, Emotional Behavior Regulation. Extended Abstract Introduction Learning disability is a neurodevelopmental disorder with biological roots that has three characteristics of reading, writing and mathematics. This disorder affects the normal pattern of learning (American Psychiatric Association, 2013). Research has shown that parents of children with learning disabilities experience more stress and difficulties in dealing with adverse situations compared to other parents (Gupta, 2007; Suzuki, Kobayashi, Moriyama, Kaja, & Enakagi, 2013). Stress is a general reaction to environmental demands and pressures and is associated with the limitation of people's emotional resources to effectively cope with these demands (Emond, Eyck, Kasmerelli, Robinson, Stillar, & Bledrein, 2016; Anioja & Aniojoti, 2016). Therefore, cognitive and behavioral regulation of emotion is necessary for parents with children with learning disabilities. Emotion regulation includes adjusting or maintaining experiences and expressing negative and positive emotions and indicates the type of emotion experienced, its occurrence, intensity, duration, and how to express it (Gross, 1998; Gross and Thompson, 2007). In this research, has been noted to two dimensions of cognitive and behavioral regulation of emotion. Cognitive regulation of emotion is the way of cognitive processing of a person when facing unfortunate and stressful events (Garnefski, Ban and Kraij, 2005). The cognitive regulation of emotion can be defined as the cognitive method of managing emotionally stimulated information (Pathoff, Garnevsky, Miklosi, Domingos-Sánchez et al., 2016). People who have the cognitive skills of emotional regulation can reduce or manage negative emotions well, and there is a significant relationship between emotion regulation by reducing self-harm and reducing emotional problems such as symptoms of depression, anxiety, and stress. There is (Zofari and Khademi Ashkazari, 2019). Behavioral emotion regulation also evaluates the behavioral strategies that people use to regulate their emotions after stressful or negative events. According to the findings of Garnevsky and Kraich (2019) and Tona (2020), distraction, active coping, and seeking social support are more adaptive methods to cope with stressful events, while avoidance and ignoring are less adaptive strategies. There are different approaches to helping mothers with children with learning disabilities, and one of these approaches is schema therapy. Schema therapy was founded by Yang, Klosko, and Vishar (2003) and its main goal is to change and improve the initial maladaptive schemas and it is possible to create a healthy schema (Peters et al., 2021). In the approach of schema therapy, the focus is on increased awareness and insight and the understanding of the role of schemas in maintaining problem-causing situations, as well as adjusting the activation and action of schemas (Heuntjen, Rijkboer and Arntz, 2019). Despite conducting numerous researches on the effect of schema therapy, research findings on the effect of schema therapy on mothers with children with learning disabilities are very limited. Therefore, considering the existing gap and the importance of providing effective interventions in the field of cognitive and behavioral regulation of emotion, the present study aims to investigate the effect of schema therapy on the cognitive and behavioral regulation of emotion in mothers with children with learning disabilities. Research Question Is schema therapy effective on cognitive and behavioral emotion regulation of mothers with children with learning disabilities? Literature Review Hertz and Evans (2021), showed that schema therapy through cognitive, behavioral, interpersonal and experimental interventions has reduced depressive rumination and avoidance behaviors, as well as increased the frequency of positive mood. Dadmo et al. (2018), also showed in research that schema therapy is one of the most important treatments in the treatment of personality disorders, and with schema therapy techniques, emotion regulation can be created in these people. Methodology The current research was semi-experimental and the research design was pre-test-post-test with a control group. The statistical population of this study included mothers of children with learning disabilities in Tehran in the first six months of 1400. The research sample included 30 mothers of children with learning disabilities, whose children attended exceptional elementary schools. Among the volunteer mothers, 30 mothers were randomly selected based on the entry and exit criteria. Then, cognitive and behavioral emotion regulation questionnaires were presented to them. Then these 30 mothers were randomly replaced in the experimental and control groups (15 mothers in the experimental group and 15 mothers in the control group). In the next step, the mothers in the experimental group received schema therapy for two months, while the control group did not benefit from this intervention during the research process. After the end of the intervention period, both groups answered the mentioned questionnaires again and the results of the two groups were analyzed with statistical methods of univariate covariance analysis. Results The mean and standard deviation of the dependent variables of the research in the pre-test and post-test stages, separated by two experimental and control groups, are presented in Table 1.

Before conducting this test, the assumptions of the normality of the distribution of scores, the homogeneity of the variance of the variables and the equality of the slope of the regression line were checked and all the assumptions were met.
