The study aims to examine the mediating role of mindfulness in the relationship between job boredom, job satisfaction, and turnover intention. The current research was descriptive-correlational. The statistical population consisted of all the female teachers working in the secondary education of one district of Shahre Rey in the academic year of 2022-2023, of which 303 were selected by volunteering sampling. Data were collected using the Job Satisfaction Scale (Smith et al., 1969), the Turnover Intention Questionnaire (Kim and Leung, 2007), the Job Boredom Scale (Lee, 1986), and the Five Facets Mindfulness Questionnaire  (Baer & et.al., 2004). For data analysis, correlation coefficient tests and path analysis were conducted using AMOS and SPSS software. The results showed that the direct effects of job boredom on job satisfaction (β = -0.27, p < 0.01) and turnover intention (β = 0.42, p < 0.01) were significant. Also, the indirect effects of job boredom on job satisfaction (β=0.36, p<0.01) and turnover intention (β=0.12, p<0.01) through mindfulness were significant. The causal model of job satisfaction and turnover intention based on job boredom fits with the mediating role of mindfulness in female teachers at the secondary level.

The aim of current study was to investigate the mediating role of resilience in the relationship between self-efficacy and post-traumatic growth among nurses during the COVID-19 pandemic. The research design was descriptive-correlational. From the mentioned, a total of 350  nurses selected via convinence sampling method and were examined by Tedeschi and Calhoun Post-traumatic Growth Inventory (PTGI), Scherer et al. General Self-Efficacy Questionnaire (GSE-17), and Conor-Davidson resilience scale (CD-RISK). To analyze the collected data Pearson correlation coefficient and Structural Equation Modeling were conducted. The results showed that direct effect of self-efficacy and the direct effect of resilience on the post-traumatic growth were significantly positive. Also, results showed that the mediating role of resilience in the relationship between self-efficacy and post-traumatic growth was significant. Based on the findings, it can be concluded that resilience and self-efficacy were important factors affecting nurses’ post-traumatic growth. Therefore, it is suggested that specialists by increasing resilience and self-efficacy through training and counseling interventions help nurses to manage the psychological truamas that resulted by covid-19 pandemic.

The purpose of this study was to evaluate the effectiveness of schema therapy on negative affect and perceived stress in coronary heart patients. The research method was quasi-experimental with pre-test and post-test with control group. The statistical population of the study consisted of all coronary heart patients referring to Jamaran hospital in Tehran in 2018 which were selected by purposeful sampling method. 30 of them were selected and randomly assigned into two groups of experimental (15 subjects) and control (15 subjects). Data were collected using the Denollet Negative Affect Inventory (1998) and Cohen et al. Perceived Stress Scale (1983). After the pre-test, intervention (Schema Therapy) was given to the experimental group in 10 sessions with duration of 50 minutes. At the end of group Schema Therapy program, post-test was taken from both groups. Data were analyzed using multivariate covariance test. The findings showed that by controlling the effect of the pretest between the means of the posttest for the experimental and the control group, there was a significant difference between the variables of perceived stress (F=17/897) and negative affect (F=16/082) at P<0/01 level. Based on the results of the present study, the application of this method can be useful in planning therapeutic interventions in cardiovascular.

Boredom is one of the most commonly experienced emotions during the adolescent years. Highly bored adolescents were shown to avoid schoolwork, and reduced attention, self-regulation, and motivation. An important characteristic of boredom is that it can be triggered by family environment. Although the relationship between Family Communication Patterns and boredom has been examined, there are few studies on underling mechanisms of this relationship. Therefore, the aim of present study was to investigate the mediating role of creativity in the relationship between Family Communication Patterns and boredom. In this descriptive- correlational study a total of 400 female high school students from the school of the 3th district of Tehran in the academic year of 2018-2019 were selected via cluster sampling. Data were collected using Multidimensional State Boredom Scale (Fahlman et al, 2013), Family Comminication Patterns Questionnaire (Fitzpatrick & Ritchie, 1974) and Abedi Creativity Questionnaire (Abadi, 1372). To analyze the data descriptive statistics, Pierson Correlation and path analysis were conducted. The results showed that direct effect of the family conversation orientation on the boredom was significantly negative, And direct effect of the Family conformity orientation and boredom were significantly positive. Also, results showed that mediating role of creativity in the relationship between Family Communication Patterns and boredom was significant. Based on the findings, it can be concluded that family communication patterns and creativity are important factor affecting adolescents’ boredom. Therefore, improving family communication and enhancing creativity can be a good way to support adolescent against everyday life problems and prevention boredom.

The aim of present study was to investigate the effectiveness of the positive cognitive-behavioral therapy on boredom and academic procrastination of female students. In this pretest–posttest quasi-experimental research with a control group, 34 female high school students in Shahre-Rey were selected in the academic year 2019-2020 through simple random sampling method and randomly divided into an experimental group (n = 17) and a control group (n = 17). The experimental group underwent ten sessions of positive cognitive-behavioral therapy while the control group did not receive any intervention. Data were collected through the Multidimensional State Boredom Scale (Fahlman et al., 2013) and the Academic Procrastination Scale (Solomon & Rothblum, 1984). The collected data were analyzed using multivariate analysis of covariance. The results showed a significant difference between the experimental and control groups in terms of boredom and academic procrastination.

Data analysis was performed using structural equation modeling statistical method and by the SPSS-22, and AMOS-24 software. The results showed that loneliness has a direct relationship on the academic engagement and an indirect effect on the academic engagement due to corona stress. Due to the results, authorities are required to increase academic engagement in higher education by planning intervening programs, holding workshops and presenting counseling to reduce these factors in order to increasing students' academic engagement

The aim of the current study was to examine the mediating role of maladaptive perfectionism and rumination in the relationship between family functioning and stressful life events with sleep quality in university students. The method of the present study was descriptive-correlational.  The statistical population of this study consisted of B. A Male student at Lorestan University, Khorramabad, Iran 2021. A sample of 562 students was selected using the convenience sampling method. Date collected tools include  Family Assessment Device (1983) FAD, Ruminative Responses Scale (1991) RRS, Pittsburgh Sleep Quality Index (1989) PSQI, the Positive and Negative Perfectionism Scale (2007) PANPS and Self-Rating Life Events Checklist (1997) ASLEC. Data analysis was based on structural equation modeling. The results showed that family functioning, maladjustment perfectionism, stressful life events, and rumination exert a significant and direct effect on the sleep quality of students (p<0.001). Also, results showed that the mediating role of maladjustment perfectionism in the relationship between family functioning with sleep quality (p<0.01) and the mediating role of rumination in the relationship between stressful events and sleep quality was significant (p<0.01). Based on the findings, it can be concluded that the conceptual model has a good fit and it can be inferred that family functioning, perfectionism, the experience of stressful events, and rumination were important factors affecting students’ sleep quality.

The aim of the present study was to examine the mediating role of perceived social support and psychological resilience in the relationship between gratitude and depression symptoms. The research method was basic in objective and correlational and structural equation analysis in data collection. A total of 219 individuals (82 males and 137 females) were selected from the statistical population of nurses working in Tehran in the second half of 2020 using the convenience sampling method. Data were collected using the Connor-Davidson Resiliency Scale (CDRS), Gratitude Questionnaire (GQ-6), Beck Depression Inventory-Second Edition (BDI-II), and Multidimensional Scale of Perceives Social Support (MSPSS). Pearson correlation and structural equation modeling were performed to analyze the data using SPSS-23 and AMOS-21. The results showed that the direct effect of gratitude (β = -0.19, P<0.001), the direct effect of perceived social support (β= -0.32, P<0.001), and the direct effect of psychological resilience (β = -0.41, p < 0.001) on depression symptoms were significantly negative. In addition, the results showed that perceived social support (β = -0.11, P < 0.01) and psychological resilience (β = -0.16, P < 0.01) had a significant mediating role in the relationship between gratitude and depression symptoms. The results of the current study suggest that gratitude may increase perceived social support and resilience and protect nurses from depression, which has applications for clinical interventions for nurses during the coronavirus pandemic.

The current study aimed to evaluate the reliability and validation of the Persian version of the Job Boredom Scale among Iranian teachers. The present study was descriptive-analytical, and we selected 500 teachers working in Tehran using the convenience sampling method. We collected data using Lee’s Job Boredom Questionnaire (1986), Schaufeli Work Engagement (2002), Maslach Job Burnout Questionnaire (1981), and Smith’s Job Satisfaction Questionnaire (1969). Exploratory factor analysis using principal components and confirmatory factor analysis were used to analyze the data. The results of the experimental study confirmed the factor structure of job boredom with 17 items; we classified all 17 items into uniformity, low arousal, and reluctance to work. The confirmatory factor analysis results confirmed the excellent fit of the three-factor model. Convergent validity coefficients of job boredom with burnout were 0.47, divergent validity coefficients with job satisfaction were -0.50, and job enthusiasm was -0.74. Also, the reliability of the questionnaire was evaluated by the test-retest method in quarterly periods, which had a significant correlation of 0.87 and a Cronbach’s alpha coefficient of 0.94, which showed the confirmation of reliability by the internal synchronization method. Therefore, researchers and practitioners can be suggested to use this tool in research related to determining job boredom and reviewing the job status of teachers.

The results showed that direct effect of mindfulness on rumination was significantly negative; direct effect of rumination on sleep quality and the direct effect of mindfulness on sleep quality were significantly positive. Also, results showed that the mediating role of rumination in the relationship between mindfulness and sleep quality was significant. Based on the findings, it can be concluded that mindfulness and rumination are two important factors affecting adolescents’ sleep quality.

Infertility led to personal and social problems among women. The present study was carried out with the aim of evaluating the effectiveness of acceptance and commitment therapy (ACT) on cognitive emotion regulation strategies, body image and resilience of infertile women.

The method of the current study being quasi-experimental, was with pretest-posttest design with control group. The statistical population of the study included all infertile women who had referred to Ghadir Hospital of Shiraz in 2019. Using purposeful sampling method, a total of 30 infertile women were selected and were randomly categorized as experimental and control groups. In the pre-test and post-test stages, Resilience Scale, Cognitive Emotion Regulation Questionnaire and the body Image Concern Inventory were conducted. After performing the pretest, the experimental group received ACT for 8 sessions of 60 minutes and the control group did not receive any intervention. Data were analyzed using multivariate analysis of covariance with SPSS-22 software.

The results showed that by controlling the effect of pre-test, there was a significant difference between the mean post-test of the two groups in the variables of adaptive emotion regulation strategies (F=18.173), maladaptive emotion regulation strategies (F=16.163), body image (F=17.593) and resilience (F=16.826) at the level P = 0.01.

According to the results of this study, we can make use of ACT for the improvement of emotion regulation strategies, body image and resilience of infertile women.

The aim of the current study was to investigate the moderating role of depression and mindfulness in the relationship between parental marital conflict and adolescents drug abuse tendency.

The method of the present study was descriptive-correlation. The statistical population of the study was adolescent male students in Nurabad city in 2019-2020, from which 329 adolescents and their parents were selected using multi-stage cluster sampling. Data were collected using marital conflict questionnaire, addiction scale, Beck depression inventory second edition and mindfulness five-factor questionnaire and analyzed by Pearson correlation coefficient and hierarchical regression.

The results showed that there is a significant negative relationship between mindfulness and tendency to use drugs and a significant positive relationship between parents 'marital conflict and depression with adolescents' tendency to use drugs. Also, based on the results of hierarchical regression, the moderating role of depression and mindfulness in the relationship between parental marital conflict and adolescent drug use tendencies was confirmed.

The present study highlights the moderating role of depression and mindfulness as an important mechanism in the relationship between parental marital conflict and adolescent drug use tendencies. Therefore, the results are of considerable practical and theoretical importance in intervention and prevention of drug use among male adolescents.

The aim of present study was to investigate the mediating role of academic entitlement in the relationship between permissive parenting and psychological distress. The research method was descriptive-correlational. Statistical population was B.A Male students at the Lorestan University, Khorramabad, Iran. A total of 282 students were selected using voluntary response sample method. Data were collected using Academic Entitlement Scale (AES), Parenting Authority Questionnaire (PAQ) and Depression, Anxiety and Stress Scale (DASS-21). To analyze the data Pearson correlation and structural equation modeling (SEM) were conducted. The results showed that direct effect of permissive parenting on psychological distress, the direct effect of permissive parenting on academic entitlement and the direct effect of academic entitlement on psychological distress were significantly positive. Also, results showed that mediating role of academic entitlement in the relationship between permissive parenting and psychological distress was significant. The current study findings indicate that permissive parenting style can increase psychological distress among university students by strengthening of academic entitlement beliefs.

For some people and in certain situations, shopping may be unplanned, sudden, and accompanied by a strong urge to feel pleasure or excitement. This type of repetitive, chronic and extreme buying behavior is known as compulsive buying. A review of the research literature shows that compulsive buyers experience adverse consequences such as feelings of guilt and remorse, academic dysfunction, financial problems, family conflicts, negative parenting, eating and sleeping disorders, and even suicide attempts. Therefore, it is important to identify and characterize the factors that influence compulsive buying. A substantial body of literature has established the links between family emotional climate and subsequent compulsive buying. Nevertheless, the perception of family climate does not always result in compulsive in buying as the development of abnormal behaviors may involve other intermediary mechanisms jointly responsible for such a relationship. Based on research literature some variables including self-differentiation have mediated relations between family emotional climate and compulsive buying. Altogether, as mentioned before compulsive buying may pose a number of deleterious outcomes for female individuals. Therefore, focus on female university students when studying compulsive buying is highly pertinent. Although an enormous amount of research is in line with the notion that family emotional climate could predict university students’ compulsive buying, studies that have tested the mediating role of self-differentiation are minimal. Above all, the current study aimed to investigate the mediating role of self-differentiation in the relationship between family emotional climate and compulsive buying.

This cross-sectional and correlational study was conducted on B.A and M.A students of Islamic Azad University, Tehran South Branch in 2019, in Iran. A total of 239 female university student from there faculties (Human Sciences Faculty, Psychology and Education Faculty, Law and Political Sciences Faculty) selected by multistage cluster sampling strategy. There is no consensus on the sample size for path analysis. However, many researchers recommended 200 cases as the minimum sample. The inclusion criterion was the age range of 18 to 45 years old and only exclusion criterion was having psychological problems background (based on a preliminary interview and participants’ self- report). About the demographic characteristics of participants, it is noted that age averaged 29.73 years (SD = 5.67). Before completing the survey, all participants gave their written informed consent, noting that they were aware that the investigation was anonymous and confidential and that participants had the right to withdraw at any time without explanation. The Differentiation of Self Inventory (DSI), Edwards Compulsive Buying Scale (ECBS), and Family Emotional Climate Scale (FECS) were used to collect the data. The instruments were distributed by the researcher and collected in the regular classrooms. After collecting the data means, standard deviations, and Pearson correlations for the levels of family emotional climate, self-differentiation and compulsive buying, together were conducted using SPSS 23.0. Path analysis was conducted to examine the mediating role of self-differentiation using AMOS 21.0. It is note that, 12 participants missed more than 50% of items on a given scale and were excluded from subsequent analyses.

The results of Pearson correlation showed that the relationship between family emotional climate with self-differentiation (r= 0.62) was positive, the relationship between family emotional climate (r= -0.34), and self-differentiation (r= -0.51) with compulsive buying were negative that all relationship were significantly at P<0.01 level. Therefore, based on the significance relationship between the variables, the necessary condition for investigating the mediating role of self-differentiation is fulfilled. Prior to conducting path analysis, it was ensured that its basic assumptions, such as adequacy of the sample size, data distribution normality, and multi-collinearity, were established. The results showed that the research model of the relationship between family emotional climate mediated via self-differentiation had a good fit based on fitness indices. The most commonly used fitness index in model analysis is CMIN/DF, that with a value lesser than 3 in the current research model shows a good fit. The goodness of fit index (GFI), the normalized fit index (NFI), and the comparative fit index (CFI) with Values higher than 0.90 indicates an acceptable fit to the current data. Also, the root mean square error of approximation (RMSEA) with a Value between 0.05 and 0.10 shows an acceptable fit of the model. Also, the parameters of the direct and indirect relationship measurement in the research model by path analysis showed that the direct effect of family emotional climate on self-differentiation (β= 0.31, P<0.001) were positive and significant. Moreover, the direct effect of family emotional climate (β= -0.15, P<0.01), and self-differentiation (β= -0.42, P<0.001) on compulsive buying were negative and significant. Finally, results showed that the mediating role of self-differentiation (β= -0.13, P<0.01) in the relationship between family emotional climate and compulsive buying was significant.

Based on the findings family emotional climate and self-differentiation were important factors affecting female university students’ compulsive buying. A possible explanation is that inappropriate family emotional climate can reduce adolescents’ self-differentiation, and as a result, they are more vulnerable to the challenges and stressors of their life, therefore female university students try to cope with their negative conditions by excessive buying as a short-term remedy to relieve stress. In case they are relieved from buying, they are more likely to regard the excessive buying a beneficial coping strategy that contributes to potential dependence and automatic activation. The cross-sectional design, which is not the best way to evaluate causal relations, limits the results. Future longitudinal research is needed to further ascertain the particular directions and relationships among these variables. Limitation aside, the present study provided some practical implications. The findings of this study could help to guide targeted preventions and interventions for compulsive buying in female university students. Thus, mental health practitioners can educate students about the potential harms of low self-differentiation and guide them to set self- reinforcing goals to monitor their frequency and duration of compulsive buying.

Fear of disease progression as one of the most important psychological structures is one of the most common symptoms distress and stress for patients with a life-threatening disease. Fear of disease progression can be defined as a realistic reactive fear of which the person is fully aware. The aim of study was to investigate the effect of cognitive behavioral therapy on the psychological distress and fear of disease progression of patients with hashimoto's hypothyroidism. For this purpose, in a quasi-experiential   study with pre-test, post-test, follow up and control group, 32 patients with hashimoto's hypothyroidism among the patients referred to clinics of subspecialty physicians in Karaj were selected by available sample and randomly divided into experimental and control groups (n= 16 each).  The groups were evaluated for psychological distress and fear of disease progression before and after the treatment intervention and three months after the end of the research. The result of analysis   of   covariance with repeated measures showed a significant difference in fear of disease progression and psychological distress between the performance of two experimental and control groups. The results indicate the effect of cognitive behavioral therapy on the fear of disease progression and psychological distress in patients with hypothyroidism; therefore, this intervention can be used as a complementary treatment, along with medication, to improve the lives of patients with hashimoto's disease.

Research has found that problems in interpersonal relationships are positively associated with suicidal behaviors. Nevertheless, it is required to further investigate internal mechanisms underlying this relationship. So, the current study aimed to examine the mediating role of self-esteem in the relationship between loneliness and suicidal ideation. The research design was descriptive – correlational. From the male high school students’ population of Nourabad in the academic year of 2020, a total of 261 participants were selected using convenience sampling and were tested by Scale for Suicide Ideation, Rosenberg Self-Esteem Scale, and the UCLA Loneliness Scale. To analyze the data, path analysis were conducted. The findings revealed that there is a direct effect of loneliness on suicidal ideation. Also, results showed that the mediating role of self-esteem in the relationship between loneliness and suicidal ideation was significant. Based on the findings, it can be concluded that loneliness and self-esteem are two important factors affecting male adolescents’ suicidal ideation. Therefore, on the basis of the results of this study, it is necessary to develop intervention strategies regarding suicide ideation for adolescents that could be established and actively implemented to prevent adolescents’ suicide.

The current outbreak of the COVID-19 pandemic has distorted the physical, mental, and psychological condition of healthcare workers. There is a paucity of research exploring the relationship between psychological resilience and post-traumatic stress symptoms and no existing literature examining the mediating role of meaning in life in the relationship between these two constructs. The objective of the study was to examine if meaning in life mediates the relationship between psychological resilience and post-traumatic stress symptoms.

The research design was descriptive – correlational. A total of 337 healthcare workers during the COVID-19 pandemic in public hospitals in Tehran, Iran were selected using convenience sampling method. The self-administered questionnaire included demographic information, the Connor-Davidson Resilience Scale (CD-RISC), the Meaning in Life Questionnaire (MLQ), and the Impact of Event Scale- Revised (IES-R). Structural Equation Model (SEM) was employed to test whether the proposed relationships between variables involved existed.

The results showed that psychological resilience (β= -0.09, P<0.05) and meaning in life (β= -0.41, P<0.01) exert significant and negative direct effect on post-traumatic stress symptoms. The SEM analysis confirmed the mediating role of meaning in life in the relationship psychological resilience and post-traumatic stress symptoms was significant (β= -0.15, P<0.01).

The research concluded that psychological resilience and meaning in life of healthcare workers affected their psychological conditions. Efforts to reduce post-traumatic stress symptoms among healthcare workers may benefit from practices for promoting psychological resilience and meaning in life.

Workaholism as a negative condition is associated with various individual and social consequences.The aim of present study was to investigate the mediating role of rumination in the relationship between self-esteem and maladaptive perfectionism with workaholism.

The research design was descriptive – correlational. From the statistical population of health care workers in public hopitals in Tehran, a total of 316 workers were selected using voluntary sampling method. Data were collected using Ruminative Response Scale (RRS), Workaholism Battery (WorkBAT), Positive and Negative Perfectionism Scale (PNPS) and Rosenberg Self- Esteem Scale (RSES). To analyze the data structural equation modeling were conducted.

The results showed that direct effect of self-esteem on rumination (β = -0.44, P<0.001) and direct effect of on workaholism (β= -0.15, P<0.001) were significantly negative. Also, the direct effect of maladaptive perfectionism on rumination (β = 0.37, P<0.001), the direct effect of rumination on workaholism (β= 0.28, P<0.001) and the direct effect of maladaptive perfectionism on workaholism (β = 0.26, p <0.001) were significantly positive. Finally, results of bootstrapping test showed that mediating role of rumination in the relationship between self-esteem (P <0.01) and maladaptive perfectionism (P <0.01) was significant.

The present study emphasizes the mediating role of rumination as an important cognitive mechanism in the relationship between personality factors and workaholism. The findings of this study could help to guide targeted preventions and interventions for workaholism in health care workers. Therefore, paying attention to dysfunctional cognitive mechanisms and modifying them can be a good way to reduce workaholism.

The association between depression symptoms and psychological well-being has received both theoretical and empirical support, however, less is known about the moderating mechanisms in this relationship. The current study aimed to explore the moderating role of self-compassion in the relationship between depressive symptoms and psychological well-being. The research method was descriptive – correlational. The statistical population was widowed women who referred to the East Tehran Welfare Organization in 2019, and a total of 130 women were selected via a simple accidental sampling method. Psychological Well-being Scale (PWS), Self-Compassion Scale (SCS), and Beck Depression Inventory-II (BDI-II) were used to collect the data. Collected data were analyzed using hierarchical linear regression. Results showed that the relationship between depressive symptoms and psychological well-being (r= -0.54, p<0.001) was significantly negative. Also, results of hierarchical regression confirmed the moderating role of self-compassion in the relationship between depressive symptoms and psychological well-being (β= -0.23, p<0.01). The present study highlights the moderating role of self-compassion as an underlying mechanism between depression symptoms and psychological well-being. Therefore, increasing self-compassion in widowed women could be a good way to protect them in the face of adversity and suffering in life.

Today, employees’ turnover is regarded a challenge in any organization and leave of any employee impose heavy cost on organization. Hence, the aim of current study was to determine the mediating role of perceived organizational support in the relationship between dark personality triad and turnover intention.

The research study was descriptive - correlational. The statistical population of the study consisted of the staff of the Central Bank in Tehran who was employed in the year 1398. Data were collected using Turnover intention scale (Kim and Leung, 2007), Dirty Dozen scale (Jenson & Webster, 2010), Perceived Organizational Support Scale (Eisenberger et al, 1986), and analyzed using structural equation modeling.

The results showed that the direct effect of Machiavellian on turnover intention (ß=0.25،P<0.01), narcissistic on turnover intention (ß=0.48،P<0.01), Psychopath on turnover intention (ß=0.26،P<0.01) is positive and significant; and the direct effect of perceived organizational support on turnover intention (ß=-0.31،P<0.01) is negative and significant. Finally, the results of the Bootstrap test showed that perceived organizational support in the relationship between Machiavellian and turnover intention (ß=-0.011،P<0.05), between narcissistic and turnover intention (ß=0.012،P<0.05) and between psychopath and turnover intention (ß=0.011،P<0.05) has a mediating role.

Therefore, central bank officials can take steps to reduce the negative impact of the dark triad of personality and prevent the turnover intention so that employees can perceive the attention and support of the organization.

Identifying suicide risk factors is important in intervening in suicide among adolescents. So, the aim of current study was to investigate the mediating role of rumination in the relationship between stressful life events and suicide ideation. The research design was descriptive – correlational. From the male adolescents’ population of Nourabad in academic year of 2019-2020, a total of 318 high school students were selected via multistage cluster sampling method and were tested using Stressful Life Events Inventory (Paykel, Brigitte, Prusoff & Uhlenhuth, 1971), Ruminative Response Scale (Nolen-Hoeksema & Morrow, 1991) and Beck Scale For Suicide Ideation (1979). To analyze the data Pearson correlation and structural equation modeling were conducted. The results showed that direct effect of stressful life events on rumination (β = 0.49, P< 0.001), direct effect of rumination on suicide ideation (β = 0.68, P< 0.001), and the direct effect of stressful life events on suicide ideation (β = 0.11, P< 0.01) were significantly positive. Also, results showed that the mediating role of rumination in the relationship between stressful life events and suicide ideation was significant (β = 0.33, P< 0.01). Based on the findings, it can be concluded that stressful life events and rumination as a cognitive element are two important factors affecting adolescents’ suicide ideation..

Mental disorders’ symptoms affect bio-psycho-social and spiritual conditions in cardiovascular patients. The current research has aimed to investigate the role of mental disorders’ symptoms in the prediction of death depression and death among hospitalized cardiovascular patients.

In this correlational study, a total of 282 individuals have randomly sampled among the employees of the Martyrs Department of Tehran Province in 2019. Data were collected using the Career Adapt-Abilities Scale (Savicas, 2012), Job Crafting Questionnaire (JCQ; Slemp & Vella-Brodrick, 2013), and Utrecht work Engagement Scale (Schaufeli et al., 2002) and were analyzed using Structural Equation Modeling.

The results showed that the direct effect of career adaptability on job crafting (β = 0.38, P<0.01), the direct effect of job crafting on work engagement (β= 0.45, P<0.01), and the direct effect of career adaptability on work engagement (P<0.01, β = 0.23) were significantly positive. Also, the results showed that the mediating role of job crafting in the relationship between career adaptability and work engagement was significant (β = 0.17, P<0.01).

it can be concluded that when companies create a space for employees, they can express their occupational adaptability at work through the design of their workplace, which is related to occupational commitment.

Despite several benefits, research has found that problematic smartphone use is positively associated with behavioral problems. However, the internal mechanisms underlying this relationship need further investigation. So, the current study aimed to investigate the mediating role of sleep disturbance in the relationship between problematic smartphone use and aggression.
The research design was descriptive-correlational. Also, the study population included the male university students of the Islamic Azad University of South Tehran Branch in the academic year of 2019-2020. Using the convenience sampling method, a total number of 213 participants from two faculties (Faculty of Human Sciences and Faculty of Law and Political Sciences) were selected and tested by Buss-Perry Aggression Questionnaire, Smartphone Addiction Scale-Short Version, and Pittsburgh Sleep Quality Index. Then, the Pearson correlation and path analysis were conducted to analyze the data. 
The results revealed the significant and direct effects of problematic smartphone use on aggression (β=0.12, P<0.05), sleep quality on aggression (β=0.37, P<0.001), and problematic smartphone use on sleep disturbance (β=0.42, P<0.001). Also, sleep quality significantly mediated in the relationship between problematic smartphone use and aggression (β=0.15, P<0.01). 
According to the present findings, problematic smartphone use and sleep disturbance are two important factors affecting aggressive behavior among university students. These findings highlight the critical role of early intervention for aggression with a focus on those with problematic smartphone use and more specifically those with sleep disturbance.
