Obsessive -compulsive disorder can lead to emotional and physical distance between couples. Excessive control over emotions prevents self-stimulation in the relationship and disrupts intimacy, which is a major problem for patients with obsessive-compulsive disorder. the present study was conducted with the aim of predicting marital intimacy based on object Relations and social cognition in couples with obsessive-compulsive symptoms.The current research was a regression type in terms of the fundamental objective and in terms of collecting correlational data.The statistical population of the present study was couples with obsessive-compulsive symptoms .Screening among 500 couples according to the entry criteria was conducted and 136 people were selected in an available manner.Pearson's correlation test and stepwise regression were used to analyze the findings.The results of Pearson's test show that object Relations and its subscales have a positive and significant relationship with marital intimacy at the 0.01 level, and social cognition does not have a significant relationship with marital intimacy, object Relations, and its subscales.Social cognition in couples with obsessive-compulsive disorder should be further investigated.On the other hand, By improving the quality of object Relations and its subscales, an effective step can be taken to increase the marital intimacy of couples with obsessive-compulsive symptoms

The aim of this study was to investigate the effectiveness of cognitive-behavioral therapy on repetitive thoughts and negative meta-exciting dimensions in women with obsessive-compulsive disorder. The present study was a semi-experimental study of the pre-test-test design with the control group. The statistical population of the study consisted of all women with obsessive-compulsive disorder referred to psychiatric services medical centers in Mashhad, of whom 24 were selected by available sampling and then were replaced in experimental and control groups (each group of 12). Data were collected using  Repeated NegativeAfter that, the therapeutic intervention was performed based on Leahy's pattern cognitive-behavioral approach for the experimental group during 8 sessions of 90 minutes, but the control group was placed on the waiting list. After the end of the treatment period, a post-test was performed in both groups. The results of covariance analysis showed that there was a significant difference in recurring thoughts and negative meta-exciting dimensions. The experimental group showed a significant decrease compared to the control group. Identifying, challenging, and correcting negative repetitive thoughts, and dysfunctional schemas and identifying hopeless thoughts and emotions and challenging them is the main goal of cognitive-behavioral therapists.

Obsessive compulsive disorder has a wide prevalence in human society. Based on this, it is of great importance to know the cognitive, behavioral and neurological backgrounds of these patients and the effective methods of therapeutic interventions to improve their conditions. The aim of the current research was to compare the cognitive, emotional and neurological profile of people with obsessive compulsive symptoms with normal people.

The present study was a correlational descriptive study. The statistical population consisted of all people with symptoms of obsessive-compulsive disorder in the second half of 1400 in Mashhad, who entered the research through an invitation. After conducting the screening interview and checking the criteria for entering the research, 80 people were selected as the research sample. The research tools included the Stroop color word test, Wisconsin cards, anxiety sensitivity, ambiguous scenarios, Googlen behavioral disorders questionnaire, Yale Brown obsessive compulsive disorder questionnaire and uncertainty intolerance scale. In order to analyze the data, partial least squares (PLS) approach was used due to the exploratory nature of the model, the small sample size, and the non-normal distribution of the variables. Analyzes were performed with SPSS.25 and SmartPLS.3.3.2 software. The findings showed that the trajectory of predicting obsessive-compulsive symptoms by five indicators was significant in all dimensions. Based on this, it was found that from the cognitive indicators, congruent reactions (P < 0.01), incongruent reactions (P < 0.01) and ambiguous scenarios (P < 0.01), among the neurological indicators (01 P < 0.01) and completion of classes (P < 0.01), among the emotional indices of anxiety sensitivity (P < 0.01) and intolerance of uncertainty (P < 0.01) and among the behavioral indices of behavioral tendencies Consistency (P<0.01) and impulsive behavior tendencies (P<0.01) were significant predictors for OCD symptoms. These results indicate that in explaining the psychological profile of obsessive-compulsive sufferers, the need to pay attention to cognitive, behavioral, emotional and neurological indicators has an important place. Also, based on these findings, it was found that emotional indicators have the highest level of predictability and behavioral indicators have the lowest level of predictability among the investigated indicators.

Depression and obsessive-compulsive disorders are common mental health problems in people, and several factors play a role in these disorders. One of the most important components of mental health is the locus of control. The aim of this study was to compare the locus of control and mental health in depressed and obsessive-compulsive patients. The research method was descriptive and causal-comparative with the participation of 140 people (70 people with obsessive-compulsive disorder and 70 people with depression) from outpatients referred to Kermanshah psychiatric clinics in 2021. The instrument of the present study included the General Health Questionnaire (GHQ) and Ratter Locus of Control Questionnaire. Data were analyzed using descriptive statistics and independent t-tests. The results showed that the locus of control of most people (82.1%) was external and the score of mental health and its components were moderate. Although the variables incloud social dysfunction, anxiety disorder, and physical symptoms were more prevalent in obsessive-compulsive disorder than in depressed individuals, this difference was not statistically significant. Depression was more common in depressed people than in obsessive-compulsive disorder, and the difference was statistically significant. Mental health was significantly weaker in obsessive-compulsive disorder than in depressed individuals, although locus of control was not significantly different in the two groups of patients. Depressed and obsessive-compulsive patients have different personality traits, at least in some components of mental health, although they did not show a statistically significant difference in the locus of control, which can be considered to control and treat mental disorders.

The aim of the present study was the determination of the efficiency of Cognitive -Behavioral therapy (CBT) on Dysfunctional cognitions in individuals with Obsessive - compulsive disorder (OCD) Symptoms. Regarding the aim, 30 individuals with Obsessive - compulsive disorder (OCD) Symptoms using random sampling method selected and arranged into two groups (examine and control group each 15 person). The efficiency of the intervention evaluated in pretest - posttest and one - month follows up. In order to evaluate the symptoms of Obsessive-compulsive disorder (OCD) , Semi - structured diagnostic interview, a Structured Clinical Interview for DSM - IV Axis I Disorders (SCID - I) , and the Obsessive Beliefs Questionnaire 44 questions (44 - OBQ) were used. The analysis of data showed that cognitive - behavioral therapy was effective in reducing Dysfunctional cognitions in individuals with OCD symptom. The results showed that posttest scores reduced in all variables. In fact, reduction in scores of Dysfunctional cognitions indicates the effectiveness of the intervention. In addition, results showed that the Cognitive - Behavioral therapy (CBT) could significantly reduce the components of responsibility, perfectionism, importance and controlling thoughts. The results showed that for the studied groups in the component of sense of responsibility / assessment of risk and threat )sig =0.139, f =4.52 (perfectionism / need to gain confidence and certainty )sig=0.158 and f=5.26( and the importance and control of thoughts )sig=0.179, f=6.12( are significant. Also, the effect of group × time is significant (sig=0.001, f = 66.91).

The aim of this study was to determine the mediating role of fear of self in the relationship between ethical sensitivity with obsessive-compulsive symptoms and sleep problems in students. The research method was correlational (structural equations) and the statistical population of the study was all students of Semnan University in the academic year 2019-2020. Using the available sampling method, 400 students participated in the research through on the university social network. The instruments used include the Obsessive–compulsive Disorder- revision, Pittsburgh Sleep Quality Index, Ethical Sensitivity Scale and Fear of self questionnaire. Structural equation method were used to evaluate the proposed model. Findings showed that ethical sensitivity had a direct relationship with symptoms of obsessive-compulsive and sleep problems and fear of self had a mediating role in the relationship between ethical sensitivity and symptoms of obsesive-compulsive and sleep problems and the model had a good fit. Ethical sensitivity is associated with sleep problems and symptoms of obsessive-compulsive when fear of self had high. It is suggested that in treating sleep problems and reducing the symptoms of obsessive-compulsive , the role of fear of self and ethical sensitivity should also be considered.

Various studies have investigated the effectiveness of Exposure and Response Prevention (ERP) on obsessive-compulsive disorder and depression, but few studies have examined ERP in a competitive trial with other methods such as mindfulness-based cognitive-behavioral therapy (MBCBT).

The purpose of this study was to compare the effectiveness of two methods of mindfulness-based cognitive-behavioral therapy (MBCBT) and Exposure and Response Prevention (ERP) on obsessive-compulsive disorder and comorbid depression in women with obsessive-compulsive disorder.

This study was designed as an “applied and quasi-experimental research” with pretest-posttest and follow-up design with two experimental groups 1 and 2 and control group. The statistical population in this study included all women in the age group of 20 to 45 years who referred to Amina and Rayen Psychological Services and Counseling Center in Tehran in 2018, 36 of whom were selected through purposeful sampling and were divided into three groups: 1) MBCBT group (n = 12), ERP group (n = 12) and control group (n = 12). Research tools included the Yale Brown Obsessive-Compulsive Disorder Questionnaire (Goodman, 1986) and the Beck Depression Inventory 2 (Beck, 1979). Data analysis was performed using repeated measures analysis of variance test by SPSS-21 software

In the post-test phase, both interventions had a significant effect on obsessive-compulsive disorder and depression (p >0.05). In the follow-up phase, two interventions significantly reduced obsessive-compulsive disorder and depression, but MBCBT was more effective.

Based on the findings of this study, it can be concluded that MBCBT and ERP can be used to reduce the rate of obsessive-compulsive disorder and depression in women with obsessive-compulsive disorder.

The aim of the present study was to investigate the mediating role of psychological distress (stress, anxiety and depression) in the relationship between experiential avoidance and symptoms of obsessive-compulsive in students. The research method was descriptive-correlational (structural equations, path analysis) and the statistical population of the study was all students of Semnan University in the academic year 2019-2020. Using the available sampling method, 311 students participated in the research through an online call on the university social network. The instruments used in this study include the Obsessive–compulsive Disorder- revision (Foa, Huppert, Leiberg, Langner, Kichic, Hajcak & Salkovskis), Acceptance and Action Questionnaire (Bond, Hayes, Baer, Carpenter & Zettle) And the scale of depression, anxiety, and stress (Lovibond & Lovibond). Pearson correlation test and path analysis method were used to analyze the data. Findings showed that experiential avoidance has a direct and significant relationship with the symptoms of obsessive-compulsive and psychological distress (stress, anxiety and depression) has a mediating role in the relationship between experiential avoidance and symptoms of obsessive-compulsive and the model had a good fit. According to the research results and the mediating role of psychological distress (stress, anxiety and depression) in the relationship between obsessive-compulsive symptoms, planning to promote psychological resilience can play an important role in reducing obsessive-compulsive symptoms due to psychological distress (stress, anxiety and depression) Have.

The aim of this study was to evaluate the effectiveness of an integrated training package of three therapies based on acceptance and commitment (ACT), mindfulness-based cognitive therapy (MBCT) and schema therapy (ST) on interpersonal relationships in patients with obsessive-compulsive disorder. Algebra was performed.

This research was conducted experimentally with a pre-test-post-test design with a control group with a follow-up phase (quarterly). According to the inclusion criteria of all male and female clients of Nikta Clinic with the diagnosis of obsessive-compulsive disorder, in the pre-test conditions, they answered the interpersonal communication skills questionnaire (Matson et al., 1995) and those with a standard deviation. They obtained lower (below score 62) in this questionnaire, 77 people were screened and 30 of them were randomly selected and replaced in 2 experimental and control groups (15 people in each group). Then, the experimental group underwent 20 sessions (each session for 120 minutes and two sessions per week) of a research package and a combination of three approaches of acceptance and commitment therapy, mindfulness-based cognitive therapy and schema therapy. At the end of the treatment period, again in the post-test phase, both groups were asked to answer the research questionnaire. Finally, after three months, follow-up was performed and the effect of this method was evaluated.

The results showed the effectiveness of a combination of three approaches based on acceptance and commitment, mindfulness-based cognitive therapy and schema therapy on interpersonal relationships in the experimental group (F = 30.12, P 00 0.001). Also, three months after the sessions related to integrated therapy, in the follow-up phase, the integrated protocol was still effective on interpersonal relationships (p <0.001).

This study aimed to compare schema modes, childhood trauma, and object relationships in individuals with borderline personality and obsessive-compulsive disorder symptoms. The research method was causal-comparative and the statistical population of this study included all people who were referred to public and private counseling centers in Tehran city in 2019, of whom 90 people with borderline personality symptoms and 90 people with obsessive-compulsive symptoms were selected by convenience sampling method. Research tools include Millon Clinical Multiaxial Inventory (1983) (MCMI); Schema Mode Inventory by Lobbestael et al. (2010) (SMI); Childhood Trauma Questionnaire by Bernstein et al. (1994) (CTQ) and Bell Object Relations and Reality Testing Inventory (1986) (BORRTI). Data were analyzed using analysis of variance. Individuals with borderline personality disorder symptoms in the components of angry child mode (P<0.05), impulsive child mode (P<0.01), undisciplined child mode (P<0.05), self-aggrandizer mode (P<0.01), emotional abuse (P<0.05), emotional neglect (P<0.01), egocentricity (P<0.05) and insecure attachment (P<0.01) obtained higher mean scores than people with obsessive-compulsive disorder symptoms. Individuals with obsessive-compulsive disorder symptoms in the components of detached protector mode (P<0.01), punishing parent mode (P<0.05), and demanding parent mode (P<0.01), and social incompetence (P<0.01) obtained higher mean scores than people with borderline disorder symptoms. Based on the present study results, it seems that object relationships, schema modes, and childhood traumas play a role in the formation of borderline personality disorder and obsessive-compulsive personality symptoms.

obsessive-compulsive disorder is a serious disorder that affects other psychological and cognitive processes of adolescents. Therefore, this study was conducted with the aim of determining the effectiveness of emotion-based cognitive therapy on cognitive flexibility and rumination of adolescents suffering from obsessive-compulsive disorder.

The research method was semi-experimental with a pre-test-post-test design and follow-up with a control group The statistics of the research were all adolescents with obsessive compulsive disorder in the city of Tehran in 2021. The sample size of the study included 30 adolescents with obsessive-compulsive disorder who were selected by the available sampling method and according to the inclusion and exclusion criteria of the study. The experimental group received 10 90-minute weekly sessions of emotion-oriented cognitive therapy intervention. The questionnaires used in this research include the obsessive-compulsive questionnaire (Hodgson and Rachman, 1977); Cognitive Flexibility Handbook (Dennis & Vanderwaal, 2010); Questionnaire was rumination responses (Hoeksma and Marver, 1991). The data were analyzed by variance analysis with repeated measurements in spss software version 22.

The findings showed that in the post-test there was a significant difference between the experimental and control groups in terms of cognitive flexibility and rumination of adolescents suffering from obsessive-compulsive disorder (P<0.001). In other words, emotion-oriented cognitive therapy intervention improved the cognitive flexibility and rumination of adolescents suffering from obsessive-compulsive disorder.

According to the findings of the present study, it is possible to suggest emotion-oriented cognitive therapy intervention as an effective method to increase the cognitive flexibility and rumination of adolescents suffering from obsessive-compulsive disorder.

Present study aimed to determine the effect of resilience training on anxiety components in primary school children. This study was quasi-experimental with a pretest and posttest design with a control group. The research population was male students referred to education counseling centers of 5 and 6 districts of Tehran city in 2019-20 academic years. The research sample was 40 people who were selected by available sampling method and randomly assigned into two equal groups. The experimental group trained 9 sessions of 60 minutes (two sessions a week) with the resilience training method and the control group didn’t received any training. Data collected with using the demographic information form and revised child anxiety and depression scale (Chorpita and et all, 2000) and analyzed by methods of chi-square and multivariate analysis of covariance in SPSS-21 software. The findings showed that the in the experimental and control groups didn’t significant difference in terms of educational level, age and education of parents (P>0.05). Other findings showed that resilience training reduced the components of separation anxiety, social phobia, generalized anxiety and obsessive-compulsive in primary school children (p < 0.05), but hadn’t significant effect on their panic (P>0.05). According to the results of this study, planning to use the method of resilience education is necessary to reduce anxiety of primary school children.

The purpose of this study was to predict obsessive-compulsive symptoms based on anxiety sensitivity and social problem solving. This study is descriptive and correlational. The statistical population of this study was all women referring to medical centers of Rasht in 2018 from which 167 patients were selected through convenience sampling. Data were collected using the Maudsley Obsessive-Compulsive Inventory (MOCI), Anxiety Sensitivity (ASR-R) and Social Problem-Solving Questionnaire (SPSI). Data were analyzed using Pearson correlation coefficient and multiple regression analysis. The results showed that anxiety sensitivity and social problem solving had a significant relationship with obsessive-compulsive symptoms (P<0.01). Anxiety sensitivity (ß=0.47), positive orientation (ß=-0.25), negative orientation (ß=0.33), avoidance problem solving (ß=0.36), impulsive problem solving (ß=0.69), and logical problem solving (ß=-0.47) significantly predicted obsessive-compulsive symptom (P<0.01). The results indicate that the more anxiety levels decrease and social problem-solving increases, the greater the degree of obsessive-compulsive symptoms in patients. Therefore, therapists need to pay more attention to the social and anxiety dimensions of patients with obsessive-compulsive disorder.

The present research has aimed to compare efficacy of cognitive-behavioral and metacognitive approaches on thought fusions and washing-cleaning obsessions in patient with obsessive-compulsive disorder. The study utilized quasi-experimental design with pretest - posttest model has two experimental groups. The population included all of the girl students at the university of science and technology of Iran in 2014-2015.initial sampling by the recall of implementing the study was conducted voluntary and all the voluntaries completed Padua inventory and among them 12 people who suffered from obsessive-compulsive disorder and verified by clinical psychologist ( base on DSM5) were selected by available sampling and randomly divided into two groups of cognitive-behavioral (n=6) and metacognitive (n=6) groups. Then all patient filled Thought Fusion Instrument and cognitive-behavioral and metacognitive interventions was applied. each of interventions was performed in 10 sessions (2 hours per sessions).in order to analyze mixed multi factorial ANOVA and repeated measure one way ANOVA methods has been used. Both metacognitive therapy (P<0.001) and cognitive-behavioral therapy (P<0.001) were effective in reducing thought fusion at the end of treatment and after a one-month follow-up. In addition, Both metacognitive therapy (P<0.001) and cognitive-behavioral therapy (P=0.001) were effective in reducing obsessive-compulsive disorder. Also, There was no significant difference between the effectiveness of cognitive-behavioral and metacognitive approaches on thought fusion (P=0.07), at the end of treatment and after one month follow-up. So metacognitive therapy as new therapeutic areas to the extent of psychology, is effective as much as cognitive-behavioral therapy in reducing thought fusion and symptoms of obsessive-compulsive disorder and it’s subscales, and can be used as an alternative treatment.

The purpose of this study was to compare the efficacy of Exposure and Response Prevention Therapy (ERP), Cognitive-Behavior Therapy (CBT) and Third-Wave Behavior Therapies on Obsessive-Compulsive Disorder (OCD) in Iranian population. The research method was a meta-analysis and the statistical population of all researches conducted in Iran between 2005 and 2017 was 58 studies that among them, 34 studies were selected according to the inclusion and exclusion criteria as the research sample and finally reported 13 effect sizes for ERP, 19 effect sizes for CBT and 12 effect sizes for Third-Wave Behavior Therapies. The effect size index was the standardized mean difference also statistical analysis was done by comprehensive meta-analysis software. The results showed that ERP (d= 1.815, P= 0.05), CBT (d= 1.542, P= 0.05) and Third-Wave Behavior Therapies (d= 1.688, P= 0.05) had been effective for OCD. In addition, study of type of treatment as a moderating variable didn’t show significant difference. Based on the findings of this meta-analysis, it can be concluded that exposure is the most important therapeutic process in the treatment of OCD which it is an essential component in all three therapeutic approaches, and probably adding cognitive, mindfulness and acceptance components will not significantly contribute to the efficacy of behavioral therapy based on ERP in Iranian patients with OCD.

This study was conducted with the aim of comparing perfectionism and the source of health control in in patients with Obsessive-Compulsive Disorder (OCD) and depressed patients. Method was casual-comparative and statistical population included all outpatients referred to Hamrah psychiatric center under supervision of welfare organization of Karaj city in the year 2015 who totally were 487 people. Among them 60 patients with OCD and 60 depressed patients who met the criteria of the study were selected using convenience sampling and the subjects completed the Frast Marten, Lhart and Rosenblate (1990) multidimensional perfetctionism scale (FMPS) and Wollaston, Wollaston and Dolis (1978) multidimensional health locus of control scale (MHLC). Data was analyzed using MANOVA & ANOVA. Results showed that the obsessive patients had more levels of perfectionism (F= 18.12, P= 0.001) and its dimensions namely worry over mistakes (F= 17.45, P= 0.003), parental expectations (F= 11.34, P= 0.01), uncertainty in the works (F= 28.25, P= 0.0001), individual criteria (F= 10.67, P= 0.01), parental criticism (F= 16.32, P= 0.004), desire to be disciplined and organized (F= 18.58, P= 0.002), internal health locus of control (IHLC) (F= 61.28, P= 0.001), powerful others health locus of control (PHLC) (F= 79.54, P= 0.0001), chance health locus of control (CHLC) (F= 63.23, P= 0.00) compared to depressed patients. It seems that higher levels of perfectionism and its components in obsessive patients lead to mental and behavioral activation; that's why they have better health locus of control than depressed people. Thus, it is recommended for the prevention of depression and its treatment some behavioral activation plans to be developed.

working memory is the comprehensive cognitive system that embedded attentional and memorical mechanisms and therefore can be used in systematic research of cognitive problems. The aim of this study was to investigate the predictive role of working memory capacity and executive functions (shifting, inhibition and updating) for Obsessive Compulsive Disorder. We selected 164 student (90 male and 74 female) from university of Tehran with random sampling method and they completed Maudsley Obsessional – Compulsive Inventory (Hodgson & Rachman, 1977), the Digit Backward Span Task (workingmemory capacity), Forward Span task (Short Term Memory), Stroop (inhibition, Spreen & Strauss, 1998), Set- Switching Task (shifting, Rogers & Monsell, 1995) and Keep Track Task (updating, Martinez, et al., 2011). Data analyzing used regression showed working memory and executive function totally predict considerable amount (67 percent) of obsessive compulsive predisposition. Therefore it can be concluding, obsessive people have crucial weakness in storage, monitoring and executive cognitive function (in general attention control) and we can use training in these functions as treatment strategies.

The present research has aimed to compare efficacy of cognitive-behavioral and metacognitive approaches on obsessive-compulsive disorder. The study utilized quasi-experimental design with pretest - posttest model has two experimental groups. The population included all of the girl students educating for B.S and M.S graduation degree at the university of science and technology of Iran in 2014-2015. Initial sampling by the recall of implementing the study was conducted voluntary and all the voluntaries completed Padua inventory and among them 12 people who suffered from obsessive-compulsive disorder and verified by clinical psychologist ( base on DSM5) were selected by random sampling and randomly divided into two groups of cognitive-behavioral (n=6) and metacognitive (n=6) groups. Then cognitive-behavioral and metacognitive interventions applied. Each of interventions performed in 10 sessions (2 hours per sessions). In order to analyze mixed multi factorial ANOVA and repeated measure one way ANOVA methods has been used. Both metacognitive therapy and cognitive-behavioral therapy were effective in reducing symptom of obsessive-compulsive disorder, at the end of treatment and after a one-month follow-up. Also, there was no significant difference between the effectiveness of cognitive-behavioral and metacognitive approaches on obsessive-compulsive disorder, at the end of treatment and after one month follow-up. So metacognitive therapy as new therapeutic areas to the extent of psychology, is effective as much as cognitive-behavioral therapy in reducing symptoms of obsessive-compulsive disorder and it’s subscales, and can be used as an alternative treatment.

There is a few research that have examined on neuropsychological ­deficits in Obsessive Compulsive Personality disorder (OCPD). In addition, neuropsychological disfunction ­can also be in relationship with obsessive compulsive personality symptoms. OCPD symptoms like rigid bounds to rules, can be compensation for cognitive deficits, and in other hand, considering the relation between OCPD and obsessive compulsive disorder (OCD), and regarding neuropsychological functions pattern in OCD, It is hypothesized that patients with OCPD also showed deficits in neuropsychological assessments. So ­neuropsychological profile of patients with OCPD and OCD have been compared with control healthy participants. In the present study, a neuropsychological test battery was administered to patients with OCPD, OCD and control healthy participants. Results of multivariate analysis of variance (MANOVA) showed that there is a significant difference in neuropsycological assessments of cognitive flexibility, problem solving and working memory between patients with OCPD and OCD. Our results suggest that OCD and OCPD patients have cognitive impairment in cognitive flexibility, problem solving and working memory. However impairment pattern was differed between OCD and OCPD patients.

This research was conducted to study the relationship between the academic procrastination behaviour of university students with perfectionism, obsessive – compulsive and five factor personality traits. Study was performed on Azarbaijan University of Tarbiat Moallem. The sample consisted of 265 students, which were selected through cluster random sampling method. The instruments employed in the study were The Almost Perfect Scale-Revised (APS-R), Padua Inventory” developed by Sanavio, Five Factor Model Personality Scale, Procrastination Assessment Scale – student(SPSS). Data were analyzed by multiple regression method. The results showed that perception of a discrepancy between those standards and actual performance, conscientiousness, openness, obsessive –compulsive personal traits were important predictive factors of procrastination behaviors. Also it was found that 35% of the variance of procrastination were accounted by linear combination of standards and actual performance, Conscientiousness, Openness, and obsessive –compulsive personal traits.
