Abstract
Individuals with emotional problems experience uncontrollable and intensive negative affect. They do not have the ability to manage and regulate their acute emotional experiences. The main aim of the present study was to compare alexithymia and defense mechanisms among patients with Major Depression Disorder (MDD), Generalized Anxiety Disorder (GAD), Obsessive-Compulsive Disorder (OCD) and normal individuals. A total of 160 participants (40 patients with MDD, 40 patients with GAD, 40 patients with OCD, and 40 normal individuals) participated in this study. Following a psychiatric diagnosis of the disorders, participants were asked to complete the Farsi version of the Toronto Alexithymia scale-20 (FTAS-20) and Defense Styles Questionnaire (DSQ-40). The normal group also completed the Depression Anxiety Stress Scale (DASS-21) and were selected based on Structured Clinical Interview (SCID-I). The results demonstrated that there are significant differences between clinical and normal groups in terms of alexithymia and defense mechanisms (p<0.001). Significant differences among clinical groups were also found (p<0.001). The results of the present study could be used in diagnosis and differentiate among these three high prevalent comorbid disorders. The findings could be used in preventive and therapeutical programs for emotional problems.

Abstract
Background: Given the changes in DSM and the consideration of dimensional variation, instead of category approach, the question arises as to whether transdiagnostic therapy is effective in the treatment of OCD? Aims: The purpose of this study was to investigate the effectiveness of transdiagnostic treatment on ambiguity tolerance, executive functions (accuracy and time) and memory in patients with obsessive-compulsive disorder (OCD). Method: 40 patients were selected by purposeful sampling method and randomly assigned to 2 groups of 20 subjects (transdiagnostic treatment group and control group). The tools used in the present study were: Yale Brown Obsessive Compulsory Inventory )Goodman, Price et al. 1989(, McLean ambiguity tolerance scale)McLain 2009), and Letter–Number Sequencing(Wechsler,1987) and Stroop test )Stroop,1935). Results: The results showed that transdiagnostic treatment significantly improved ambiguity tolerance, cognitive emotion regulation, executive functions (accuracy and time) and memory in patients with OCD (p<0/001). Conclusion: transdiagnostic approach in treatment by considering the dimensional approach and targeting of diagnostic structures can be effective in improving the symptoms of OCD.

Abstract
Background: The tendency to avoid negative emotions may occur in any psychological treatment process. In this regard, Robert Leahy reviewed this topic by presenting the model of emotional schemas. He believes that excitement is some sort of information. Excitements arise from the parallel processing of various information and most of them occur outside the scope of consciousness. In this regard,Robert Leahy tries to overcome this disadvantage by offering a therapeutic model based on emotional schemas. The present research question is what difference is between emotional schemas of patients with obsessive-compulsive disorder, major depression and normal people? Aims: The main purpose of the present research was comparing emotional schemas in patients with obsessive-compulsive disorder, major depression and normal people. Method: The method of this research was descriptive.The statistical population of the study consisted of all individuals with depression, obsessive-compulsive disorder, and normal people. Using available sampling method, 90 people(30 with obsessive-compulsive disorder,30 with depression and 30 of ordinary people)as sample size.In this study,questionnaires Leahy Emotional Schemas LESS(Leahy, 2002) and Structured Interview were used. Results: The statistical model used was multivariate analysis of variance and the findings showed that "obsessive rumination", "being uncontrollable" and "higher values" had significance level a:0.01, and in people with obsessive-compulsive disorder have been high. also "guilty" and "blame" had significance level a:0.01 ,and in depressed people it was higher than people with Obsessive-compulsive disorder and normal people. Conclusions: This means that the patients with obsessive-compulsive disorder had more emotional schemes than other groups.

Abstract
Background: Obsessive-compulsive disorder (OCD) is one of the disabling disorders associated with extensive personal and social costs. This disorder has a significant comorbidity with depression and anxiety disorders, and many of these patients do not respond to psychotherapy and medication. Thus can we develop a new and non-invasive brain stimulation techniques to improve obsessive-compulsive symptoms. Aims: This study aimed to investigate the effectiveness of cathodal transcranial direct current stimulation (c-tDCS) on obsessive-compulsive, anxiety, and depressive symptoms in patients with OCD. Method: Thirty OCD patients (15 patients in the experimental group and 15 patients in the placebo group) were selected by convenience sampling. In the intervention step, the experimental group received c-tDCS for 10 sessions (2 sessions per week, 20 minutes each session with 2 mA intensity) and the placebo subjects received the sham-tDCS. Subjects in both groups were evaluated using the Yale-Brown obsessive-compulsive scale(Goodman, 1989), the Hamilton anxiety rating scale(1959), and the Beck depression inventory(1978) in the first and tenth sessions. Results: The results of this study showed that the use of c-tDCS in orbitofrontal cortex and anodal transcranial direct current stimulation in O2 region resulted in significant reduction of obsessive-compulsive symptoms (p<0/001), anxiety (p<0/003), and depression (p<0/004) in OCD patients. Conclusions: tDCS is an effective non-invasive technique for the improvement of obsessive-compulsive symptoms, anxiety, and depression in OCD patients.

Abstract
Background: Obsessive-compulsive disorder (OCD) is a serious, debilitating but treatable disease. Ruminations and social anxiety are common psychological problems in patients with obsessive-compulsive disorder. The effectiveness of mindfulness training has been proven in various domains, but has been neglected the rumination and social anxiety in patients with obsessive-compulsive disorder. Aims: This study was conducted aiming to determine the effectiveness of mindfulness training on the rumination in women with obsessive-compulsive disorder. Method: This study was quasi-experimental with pre-test and post-test design with control group. Among women with obsessive-compulsive disorder referring to the clinics of the city of Tehran in the first half of the year 2019, 30 people were selected by convenience sampling and were randomly assignes to experimental and control groups. Participants completed Nolen Hoxma and Morrow (1993) Rumination Scale and Connor et al. (2000) Social Anxiety Scale. Mindfulness training sessions (Kabat-Zinn, 2003) were implemented for experimental group in eight 90-minute sessions, but no intervention was provided for the control group. The data were analyzed by analysis of covariance. Results: Results showed that mindfulness training reduced rumination and social anxiety in the experimental group (p<0/05). Conclusions: Mindfulness training can be used to reduce rumination and social anxiety in patients with obsessive-compulsive disorder.

Abstract
Background: Obsessive-compulsive disorder is one of the most common and debilitating psychological disorders. Numerous studies have examined the effectiveness of cognitive-behavioral therapies and third generation on the improvement of obsessive-compulsive disorder, But the main issue is that if new therapies such as imagery Rescripting and reprocessing therapy affect women's obsessive-compulsive disorder?
Aims: This study was implemented to study the effectiveness of imagery Rescripting and reprocessing therapy on cognitive abilities, distress tolerance and symptoms of obsessive-compulsive disorder in women.
Method: The present study is a quasi-experimental. The quasi-experimental design of the present study was pre-test, post-test and follow-up with a control group. The statistical population of this study consisted of all women aged 20 to 45 years in Kermanshah in 1397. The research sample was 40 women aged 20 to 45 years in Kermanshah who were selected by purposive sampling method and randomly assigned to the experimental and control groups. Structured clinical interview, Yale-Brown Obsessive-Compulsive Scale (Goodman et al., 1986), Nejati cognitive ability questionnaire (2013) and Simmons et al. (2005) Distress Tolerance Scale (DTS) were used to collect data. The experimental group received 12 sessions of 90 minutes imagery Rescripting and reprocessing therapy (IRRT) based on the approach of O’Shea and Moran (2019) once a week and the control group did not receive any intervention. Data were analyzed using mixed variance analysis with repeated measuring.
Results: The results of mixed variance analysis with repeated measuring showed that imagery rescripting and reprocessing therapy (IRRT) is effective in reducing cognitive problems and the symptom of obsessive-compulsive disorder and increasing distress tolerance (P≤0/001).
Conclusions: Based on the findings of this study and considering that the pattern of imagery Rescripting and reprocessing therapy Focuses on images, feeling, disturbing memories, and cognitive reconstruction, it can be considered as an effective intervention along with other therapeutic interventions for patients with obsessive-compulsive disorder Practically used.

Abstract
Background: Transcranial direct electrical stimulation is a non-invasive neuromodulation stimulation technique with good tolerance and no side effects in the treatment and improvement of obsessive-compulsive symptoms, which effectively modulates cortical excitability. However, there is still no strong and sufficient evidence for the use of this treatment method in adolescents with obsessibe- compulsive disorder.
Aims: The present study was aimed at the effectiveness of transcranial direct current stimulation on the Self-conscious Affections of Shame and Guilt and the disgust sensitivity of Adolescents with obsessibe- compulsive disorder.
Methods: In this research, the experimental method was used as a single case method with a continuous measurement design and different subjects. The statistical population of the present study included all teenagers suffering from obsessive-compulsive disorder who were referred to Yas Counseling Center in Tabriz in 1400, and 4 of them were selected by purposive sampling and based on the protocol of Green et al (2020) they underwent ten sessions of transcranial direct current stimulation twice in a week for 20 minutes each time. Subjects in the baseline stages, the second, fourth, sixth, eighth, tenth, and one-month follow-up sessions with disgust sensitivity scale (Heidet, McCauley, and Rosin, 1994), guilt questionnaire (Kugler and Fons, 1992) and shame questionnaire (Cohen, Wolff, Penter and Insko, 2011) were evaluated. For data analysis, a visual drawing method, reliable change index, percentage of recovery, and percentage of non-overlapping data were used.
Results: The results showed that transcranial direct electrical stimulation has a significant effect on reducing feelings of shame and guilt and disgust sensitivity in adolescents with obsessive-compulsive disorder (RCI≥1/96), and the therapeutic effects are maintained in the follow-up phase.
Conclusion: Adolescents with obsessive-compulsive disorder who were treated with transcranial direct electrical stimulation experienced less shame and guilt and less disgust sensitivity. It is recommended to use this method in the treatment of adolescents with obsessive-compulsive disorder.

Abstract
Background: Relationship obsessive–compulsive disorder (ROCD) is a presentation of obsessive-compulsive disorder (OCD) centering on close interpersonal relationships. ROCD is characterized by obsessive preoccupation, doubts, and compulsive behaviors focusing on one's relationship and relationship partner's qualities and properties. Despite the growing attention to ROCD, not much research has been done on the underlying, cognitive, and personality factors of the symptoms.
Aims: The study aimed to investigate the mediating role of ego strength in the relationship between perfectionism dimensions and ROCD symptoms.
Methods: The research method was correlational, structural equations modeling type. 430 participants (324 women, 106 men) were selected by convenience sampling method from students of the University of Tehran in the academic year 2022-2023. Selected individuals completed the Relationship Obsessive-Compulsive Inventory (ROCI; Doron et al., 2012), Ego Strength Scale (ESS; Besharat, 2017), and Tehran Multidimensional Perfectionism Scale (TMPS; Besharat, 2007). Research data were analyzed by Pearson correlation coefficient and path analysis using SPSS28 and AMOS28 software.
Results: The hypothesized mediation model provided fit to the data, CFI= 1, TLI= 1, RMSEA = 0.001. The correlation between perfectionism dimensions and ROCD symptoms were significantly positive (p<0.01), and between ego strength and ROCD symptoms were significantly negative (p<0.01).
Conclusion: The study findings suggest that ego strength mediated the association between perfectionism dimensions and ROCD symptoms. According to the results of this study, it can be concluded that perfectionism dimensions in ego strength can predict the severity of ROCD symptoms. Considering these variables may be important in the processes of prevention, diagnosis, and treatment of ROCD symptoms.

Abstract
Background: Obsessive-compulsive disorder is a chronic mental disorder that requires different treatments due to its complex nature. Schema therapy (ST) and exposure and response prevention (ERP) are two treatments that have been studied in people with obsessive-compulsive disorder (OCD), and previous studies have shown them to be effective. However, few studies have investigated the effectiveness of integrating these two methods in comparison with other methods.
Aims: The study aimed to compare the effectiveness of the ST and the integration of schema therapy with the exposure and response prevention technique (STERP) in treating distress tolerance in women with washing compulsions.
Methods: The research method was quasi-experimental with a pre-test-post-test design and a 2-month follow-up. The statistical population included all women with obsessive-compulsive disorder referred to counseling centers in the north and center of Tehran from the beginning of November to the end of February 2020. Forty-five people were selected by a convenience method based on inclusion criteria. The first intervention group (ST) received 12 sessions, and the second intervention group (STERP) received 14 sessions. The research instrument included the Distress Tolerance Scale (DTS) (Simmons & Gaher, 2005). Data were analyzed by mixed-design analysis of variance and Bonferroni test in SPSS-23 software.
Results: The results showed that ST and STERP interventions increased distress tolerance in women with washing compulsions at the end of interventions and follow-up period (P<0.0001), but STERP was more effective in treating distress tolerance compared to the ST.
Conclusion: The results showed that using exposure and response prevention methods integrated with schema therapy for patients with obsessive-compulsive disorder allows the them to analyze different dimensions of anxiety-inducing stimuli and provides a more appropriate answer to it.

Abstract
Background: Previous research has highlighted the potential role of inferential confusion in the development and maintenance of obsessive- compulsive disorder symptoms. In some of these studies, the factors predicting obsessive-compulsive disorder symptoms, including fear of self and obsessive beliefs, have been identified, but the mediating mechanisms of this relationship have not been identified yet.
Aims: The purpose of the present study was to investigate the mediating role of fear of self and obsessive beliefs in the relationship between inferential confusion and obsessive-compulsive disorder symptoms.
Methods: The research method was correlational and structural equation medeling. The statistical population of the study included all social network users in mashhad in year 2022, from which 300 subjects participated were selected by available sampling method. To collect research data, measures of Obsessive-Compulsive Insentory-Revised (Foa et al., 2002), Feared Self Questionnaire (Aardema et al., 2013), Obsessive Beliefs Questionnaire (OCCWG, 1997), and Inferential Confusion Questionnaire (Aardema et al., 2010) were used. Data analysis done through structural equation modeling using path analysis method by SPSS26 and AMOS22 softwares.
Results: The results showed that inferential confusion (β=0.19), fear of self (β=0.23) and obsessive beliefs (β=0.55) had a positive and significant effect on obsessive-compulsive disorder symptoms (P<0.01). Also, the direct effect of inferential confusion on fear of self (β=0.60) and obsessive beliefs (β=0.58) was significant (P<0.01). Regarding the indirect effect, inferential confusion had a significant effect on obsessive-compulsive disorder symptoms through the mediating variable of obsessive beliefs (β=0.31) and fear of self (β=0.13) (P<0.05).
Conclusion: Acording to the role of fear of self and obsessive beliefs in the relationship between inferential confusion and obsessive-compulsive disorder symptoms, planning to reduce fear of self and obsessive beliefs can reduce the effect of inferential confusion on obsessive-compulsive disorder symptoms.

Abstract
Background: Obsessive-compulsive disorder is a heterogeneous disorder with different symptoms and different subgroups. To understand this disorder and investigate its neurological basis, most of the studies have examined the function of the frontal lobe of affected people in a resting state, regardless of the heterogeneity of its symptoms and subgroups; however, the quantitative electroencephalography characteristics of all brain channels for different subgroups of this disorder have not been investigated separately and in different situations.
Aims: This study was conducted to investigate the index of asymmetry in all brain lobes of people with OCD with harm avoidance (HA) motivation in an imaginary exposure to an obsessive-provoking situation compared to the resting stage.
Methods: The current research was practical in terms of purpose and experimental in terms of method. The statistical population consisted of all OCD patients with harm avoidance motivation who were referred to the Peyvand Counselling Center in Kerman in 2022-2023. To conduct the study, 45 people were selected by a convenience method based on inclusion criteria and were evaluated by completing the Yale-Brown Obsessive Compulsive Scale (Goodman et al., 1986), Obsessive-Compulsive Core Dimensions Interview (Summerfeldt et al., 2014), Obsessive-compulsive Core Dimensions Questionnaire (Summerfeldt et al., 1999) and EEG recording. The obtained data were quantified by the Fourier transform method and statistically analyzed using paired t test and SPSS-26 software.
Results: The results showed a significant increase in theta waves in the left frontal lobe (FP1-FP2 and F3-F4), alpha waves in the left frontal lobe (F3-F4 and F7-F8) and left temporal lobe (T3-T4), and beta waves in the right parietal lobe (P3-P4) (p< 0.01).
Conclusion: The results indicated the involvement of slow waves of the left frontal and temporal lobes, and fast waves of the right parietal lobe during exposure in OCD. These findings provide the possibility of using noninvasive neurophysiological methods in the more accurate treatment of this subgroup and encourage further research on quantitative electroencephalographic features as possible biomarkers for other homogeneous subtypes of OCD.

Abstract
Background: In recent research, defects in cognitive processes have been proposed as one of the cognitive causal hypotheses, and psychological interventions can help to improve this disorder. Acceptance and commitment therapy (ACT) focuses on increasing psychological flexibility, which is the ability to pay attention to experiences in the present without bias. Metacognitive therapy (MCT) also emphasizes how a person responds to his/her thoughts and how he/she communicates with them. Conducting comparative research on these two types of treatment in patients with obsessive-compulsive disorder has received less attention.
Aims: The study aimed to compare the effectiveness of ACT and MCT in reducing insufficient executive functioning in obsessive-compulsive patients.
Methods: The current research design was a semi-experimental pre-test-post-test type with a control group. The statistical population of the research included all patients suffering from obsessive-compulsive disorder who were referred to counseling centers and psychological services in Kermanshah City in 2022. 45 of these patients were purposefully selected and randomly divided into two experimental groups (a treatment group based on acceptance and commitment and a metacognitive treatment group) and a control group (15 people in each group). The measuring tool in this research was the Wisconsin card sorting test of Grant and Berg (1993). The treatment protocol based on acceptance and commitment (Bach & Moran, 2008) and metacognitive therapy (Wells, 2008) were implemented during eight 60-minute sessions for the first and second experimental groups, respectively, but the control group did not receive any intervention. In order to analyze the data, one-way analysis of variance and SPSS-23 software were used.
Results: The results of the one-way analysis of variance showed the effectiveness of both treatment models in increasing the number of completed classes, increasing the number of correct answers, and reducing the residual error (p<0.05). Also, based on the results of Toky Post Hoc test, a significant difference was observed between the two treatment groups in the research variable, And the treatment based on acceptance and commitment has been significantly more effective in increasing the number of classes completed, increasing the number of correct answers and reducing the error remaining in participants compared to metacognitive therapy. (p<0.05).
Conclusion: The study findings suggest that both treatments were effective in improving the executive function of obsessive-compulsive patients. However, the effectiveness of ACT was significantly higher than MCT.

Abstract
Background: Obsessive-compulsive disorder (OCD) is profoundly debilitating, necessitating lifelong treatment. Various interventions have been employed to treat obsessive-compulsive disorder (OCD), but the efficacy of danger ideation reduction therapy (DIRT) on behavioral avoidance and death anxiety has not been investigated.
Aims: The aim of this study was to examine the effectiveness of danger ideation reduction therapy (DIRT) on behavioral avoidance and death anxiety in individuals with obsessive-compulsive disorder (OCD).
Methods: This study employed a pretest-posttest experimental design with a control group. The population of this study consisted of all individuals with OCD in Ahvaz in 2023. Thirty-eight individuals were selected through purposive non-random sampling and assigned to two experimental and control groups randomly. The experimental group received eight sessions of 90-minute danger ideation reduction therapy, while the control group remained on the waiting list. The Death Anxiety Scale (Templer, 1970) and the Experiential Avoidance Questionnaire (Gámez et al., 2011) were used to collect data in two stages: pretest and posttest. The data were analyzed using multivariate analysis of covariance (MANCOVA) in SPSS 24 software.
Results: The results indicated a significant difference in the mean scores of posttest between the experimental and control groups in the variables of behavioral avoidance and death anxiety in individuals with OCD after controlling for pretest effects (p < 0.05).
Conclusion: Based on the results of this study, it is recommended that mental health professionals utilize danger ideation reduction therapy as an effective intervention to reduce behavioral avoidance and death anxiety in individuals with OCD. Furthermore, organizing conferences and seminars on danger ideation reduction therapy is recommended to further promote and advance this treatment.

Abstract
Background: Obsessive-compulsive disorder is one of the most common debilitating neuro-psychological disorders, which is characterized by features such as recurrent obsessions or compulsions or both, and disrupts the life of the affected person.
Aims: This research aimed to design and validate the therapeutic protocol of accelerated resolution therapy (ART) and to evaluate its effectiveness on the clinical symptoms of obsessive-compulsive disorder (OCD).
Methods: The research was carried out in two stages, which were designed and implemented for this specific purpose. In the first stage, the initial treatment protocol was developed based on a comprehensive review of previous studies, existing methods, and guidelines. After that, the validity of the protocol was evaluated by two qualitative and quantitative methods by calculating the content validity ratio.In stage two of the research, a new protocol was tested with a single-subject study and multiple baseline controls. A 6-week follow-up was conducted to measure the protocol's effectiveness. The statistical population for this research comprised all patients diagnosed with obsessive-compulsive disorder who were referred to counseling centers in Urmia City. Out of the total population, 4 patients were selected through a structured diagnostic and clinical interview, based on the criteria of DSM-5-TR, using the available sampling method. Patients participated in the research after meeting the entry criteria and not meeting the exit criteria. The effectiveness of the treatment protocol during 3 stages (baseline, treatment, and follow-up) was evaluated using the revised obsessive-compulsive questionnaire.
Results: Based on the results of the CVR index, the developed protocol can be implemented to reduce the clinical symptoms of obsessive-compulsive disorder in patients.
Conclusion: It appears that accelerated resolution therapy may alleviate the symptoms of obsessive-compulsive disorder and should be considered in macro health management programs.

Abstract
Background: Individuals with obsessive-compulsive disorder and general anxiety suffer from attention bias. However, the lack of similar studies investigating attention bias in these groups necessiates a copmarison of attention bias between individuals with these disorders and those without.
Aims: The aim of this study was to compare attention bias among individuals exhibiting symptoms of obsessive-compulsive disorder ( washers and checkers), those with generalized anxiety disorder, and individuals without any diagnosed psychological conditions.
Methods: The methododology employed in this research is a causal-comparative (post-event) design. The statistical population of this study comprised all students enrolled at Tabriz University during the academic year 1401-1402. To identify students with symptoms of obsessive-compulsive disorder (based on Maudsley, 1997) and anxiety (following Beck, 1990) questionnaires were distributed using available methods. Subsequently, a purposive sampling technique was used to select 15 participants for each of the four groups: washers, checkers, anxious and normal. Following the selection process, participants underwent the emotional Stroop test (Stroop, 1935), which included four categories of words: disgust, anxiety, checking and neutral words to assess attention bias. The collected data were analyzed using multivariate analysis of variance (MANOVA) with SPSS-20 software.
Results: The findings revealed that participants in the washing group exhibited significantly longer reaction time to disgust words (P≤0.001) compared to the other three groups. Similarly, individuals in the checking group demonstrated prolonged reaction time to checking words compared to the other three groups (P≤0.001). Moreover, participants in the anxiety group displayed extended reaction times to the anxiety words compared to the other groups (P≤0.001).
Conclusion: Based on the findings indicating heightened attention bias among individuals with obsessive-compulsive disorder (washers and checkers) and generalized anxiety disorder compared to the normal group, it is recommended to implement therapeutic interventions and cognitive rehabilitation strategies aimed at reducing attention bias in these two groups.

Abstract
Background: Obsessive-compulsive disorder is characterized by repetitive and intrusive thoughts and actions, which are associated with thought-action fusion and reasoning deficits. Negative mental imagery is one of the factors that affects the integration of thought-action fusion and reasoning in OCD.
Aims: This study aimed to determine the effectiveness of imagery rescripting and reprocessing therapy (IRRT) in addressing thought-action fusion and reasoning in OCD.
Methods: The research was a quasi-experimental study utilizing a pre-test and post-test design with a control group. The statistical population consisted of individuals aged 18 and 40 with obsessive-compulsive disorder. 30 people were selected hrough purposeful sampling referring to psychotherapy clinics in Shiraz in 2024, and were randomly assigned to two groups: experimental (n=15) and control (n=15). As part of the pre-test and post-test, both groups were asked to listen to words, while QEEG recorded the beta wave activity of the precuneus area of the brain. 10 seconds after reading the last word, participants completed the Raven's Progressive Advanced Matrices Test (APM) and Thought-Action Fusion Scale (TAFS-R). The experimental group participated in 10 weekly sessions of IRRT, while the control group waited for intervention. Data analysis was conducted using covariance analysis.
Results: The results indicated that IRRT significantly improved the dimensions of thought-action fusion to others, to oneself, and moral, with effect sizes of (Ƞ2=0.55), (Ƞ2=0.47) and (Ƞ2=0.45) respectively, as well as reasoning ability with an effect size (Ƞ2=0.67) in OCD.
Conclusion: The IRRT model, with its techniques and methods, can reduce thought-action fusion and improved reasoning in individuals with obsessive-compulsive disorder by changing negative mental imagery.
