Aim and Background: Children's cancer is a special bio-psychological status that challenges the perceived social support and locus of control of mothers with different educational levels and affects their psychological adjustment. Therefore, the aim of this study was to investigate the direct and indirect role of education, with the mediating role of locus of control and perceived social support, on psychological adjustment of mothers of children with cancer.
Methods and Materials: This research is descriptive-correlational. The statistical population of the study consisted of all mothers of children with cancer who referred to the clinics of pediatricians of Mashhad. The sample size of 220 people was selected using targeted sampling method. Data were collected using psychological adjustment to illness scale, Rotter locus of control, multidimensional perceived social support, and demographic characteristics.
Findings: According to the results of this study, the increase in education directly and indirectly through increased perceived social support reduced maladjustment (P<.01). Also the increase in education directly related to increase in internal locus of control and decrease in external locus of control but has not indirect relationship on adjustment.
Conclusions: According to the findings, it can be concluded that increased education through perceived social support mediates the psychological adjustment of mothers. Increasing levels of education can also lead to an increase in internal control and a decrease in external control.

Aim and Background: The prevalence of coronavirus, the unknown and cognitive ambiguities of this virus and the resulting mortality rate, cause high anxiety in individual. The aim of this study was to provide a model of coronary anxiety based on locus of control, emotion regulation strategies, perceived social support and disease anxiety with emphasis on the mediating role of cognitive-behavioral avoidance in students.
Methods and Materials: The present study is of descriptive-correlation and structural equation modeling. The research population were Isfahan university students in the spring of 1400. From the population, according to Cochran's formula, 250 people were selected by available sampling and Rotter's Internal-External Locus of Control Scale (1966), Emotion Regulation Questionnaire (2004), Health Anxiety Questionnaire (2002), Perceived Social Support Questionnaire (1988), Avoidance Inventory (1994) and the Coronavirus Anxiety Scale (2019) were delivered to them virtually. Statistical analysis was performed by covariance-based structural equation modeling using Amos software.
Findings: The results showed that there is a direct relationship between the locus of control and disease anxiety with corona anxiety in students and these two variables explain 64% of the variance of corona anxiety in students (p<.05). also the results showed that cognitive-behavioral avoidance does not play a mediating role in these relationships.
Conclusions: Based on the results, it is necessary to take measures to reduce the locus of control and reduce disease anxiety in order to reduce corona anxiety in students.

Aim and Background: This study aimed to evaluate the effectiveness of bullying control training on the health-promoting behaviors of adolescent bullies: the mediating role of perceived social support.
Methods and Materials: The study design was quasi-experimental with pre- and post-test and one-month follow-up with control groups. The statistical population consisted of adolescents aged 14 to 17 years old from public schools of District 17 in Tehran. 40 adolescents who were compatible with inclusion criteria and obtained a high score in the Harter bullying scale were randomly selected and assigned to two experimental and control groups. The research tools consisted of the Perceived social support scale by Zimet et al. (1988) and the Health Promoting Behavior of Walker et al. (1987), which was completed in three phases (pre-test, post-test, and one-month follow-up) by both groups. The Bullying Control Education program was implemented at eight sessions of 90 minutes for the experimental group. Structural modeling with minor least squares approach was used in several multi-response patterns using SPSSV22 and SmartPLSV3.3 software for data analysis.
Findings: The results showed that Bullying Control Education had a positive and significant effect on Social Support and Health Promoting Behaviors in the post-test and follow-up phases. The results also showed that Bullying Control Education has an indirect and significant effect on Health Promoting Behaviors due to social support. The research model in the post-test phase was 51%, and in the follow-up phase, 54% of the variance of Health Promoting Behaviors.
Conclusions: Based on the results of this study, it can be said that the effectiveness of Bullying Control Education on Health Promoting Behaviors with the mediating role of Perceived Social Support is desirable. Therefore, teachers' knowledge, parents, psychologists, consultants, and other educational professionals from these variables can be helpful.

Aim and Background: Adolescence is considered as a critical period for early diagnosis and intervention to prevent suicidal behavior, so the etiology of effective factors for suicide is essential. Therefore, the present study was conducted with the aim of investigating the role of impulsivity, dark personality traits, perceived social support and anxiety sensitivity in predicting students' suicidal thoughts.
Methods and Materials: The type of study was descriptive-correlation. The statistical population of the study was all the male students of the second secondary level in the first district of Ardabil city in 2022-2023 (350 people), who were selected as a sample through the Karjesi and Morgan table and by multi-stage cluster random sampling. The research tools included the Impulsivity Scale by Barratt & et al (1995), Johnson and Webster's Dark Personality Traits Scale (2010), Zimet & et al's Perceived Social Support Scale (1988), Reiss and Peterson's Anxiety Sensitivity Questionnaire (1986), and Beck's Suicidal Ideation Scale (1991). Collected data were analyzed using Pearson's correlation coefficient and multiple regression analysis simultaneously in SPSS version 18 software.
Findings: According to the results, there is a relationship between impulsivity 0.69, dark personality traits (Machiavellianism 0.55, narcissism 0.57 and psychopathy 0.50), perceived social support -0.36 and anxiety sensitivity 0.69 with suicidal thoughts in male students. Statistical significance was observed. Also, using 0.64 multiple regression, suicidal thoughts of male students were explained by variables of impulsivity, dark personality traits, perceived social support and anxiety sensitivity.
Conclusions: Considering the impact of impulsivity, dark personality traits, perceived social support, and anxiety sensitivity in students' suicidal thoughts, it is suggested that psychologists and specialists pay more attention to the role of these variables to reduce students' suicidal thoughts
