Introduction: With respect to increase of job stress and disease that arise from stress in work environments, purpose of this study was investigated job stressors as predictors of psychosomatic symptoms at staff of a company in Ahwaz.
 Materials & methods: The research method of this study was descriptive-correlational kind. Statistical population comprised of all personnel of a company in Ahwaz who worked at 1392. The sample consisted of 202employees, who were selected by simple random sampling method. The instruments that apply at this study consist of: negative act, effort-reward imbalance, job content, work-family conflict, organizational justice, psychosomatic symptoms in nonclinical context questionnaires. In order to analyze research hypothesis, regression analysis and Pearson correlation, and to validity analysis, Pearson correlation and confirmatory factor analysis were used. Findings: Results of Pearson correlation indicated that support and organizational justice had a significant negative relationship with psychosomatic symptoms and effort-reward imbalance, overcommitment, job strain, work-family conflict and bullying had a significant positive relationship with psychosomatic symptoms. Results of regression analysis indicated that predictive variables were able to predict 0/41% of psychosomatic symptoms variance and workplace bullying over commitment and work-family conflict were the best predictors of psychosomatic symptoms at staff.
 Discussion & Conclusion: With respect to the results, variables that apply at this study, special variables that had a great role should be regarded at schedules to reduce job ills and increase of staff health.

Introduction: The aim of this study was to investigate the effects of sleep deprivation on the responses of cortisol and testosterone, anaerobic performance indices and blood lactate in active men. For this purpose we used active healthy subjects of physical education field with an average age of 23 ± 2.25 Height 174.5 ± 1.1 and the weight of 69.5 ± 7.8.

Materials & methods: sleep deprivation was a night that was applied by reading, playing chess, computer game and so on. Cortisol and testosterone were measured by Liaison kit mad in England. Performance indicies were measured using the maximum Wingate anaerobic power test and blood lactate were measured using lactometer at the time of fasting, before, immediately and after the 5 minutes of anaerobic test. Data analysis using dependent and independent t test were evaluated.

Findings: The results indicated that sleep deprivation than sleep leaded to significant increase in cortisol (p=0.03) and significant decrease in testosterone (p=0.01). The results showed that sleep than sleep deprivation don’t have significant differences in the performance of anaerobic power and fatigue index (p= 0.06, 0.11, 0.21) although a slight improvement in performance parameters of anaerobic power during sleep was observed. Blood lactate concentration at the time immediately after the Wingate test in sleep phase than full and partial sleep deprivation showed a significant reduction (p=0.02). At other times of rest, before and 5 minutes after the Wingate test, no significant changes (p= 0.061, 0.053, 0.61) were observed.

Discussion & conclusions: Results of this study demonstrated that sleep deprivation didn’t have significant effects on reducing the anaerobic performance and fatigue in active subjects, but concentration lactate showed significant increase after sleep deprivation and after anaerobic exercise than sleep stage. These hormonal changes may be due to stress-induced sleep deprivation and sports activities.

Introduction: Depression is the most common psychiatric disorder throughout life. One of its major consequences is an increase in suicide rates and suicide attempts. Therefore, this study aimed to compare the effectiveness of holographic reprocessing and dialectical behavioral therapy on cognitive flexibility and impulsivity in depressed patients who have attempted suicide.
 
Materials & Methods: This experimental study was conducted based on a pre-posttest design with a control group. The statistical population of this study included all depressed patients who attempted suicide in Ilam during 2018. In total 45 participants were selected through a simple random sampling and assigned randomly into three groups of holographic reprocessing, dialectical behavior therapy, and control group (15 cases per group). The data were collected using Denis and Vendoral Cognitive Flexibility Scale and The Barratt Impulsiveness Scale. The data were analyzed in SPSS software (version 21) through a multivariate analysis of covariance and the Bonferroni test. Ethics code: Ee/98.24.3.57583/SCU.ac.ir 
 
Findings: The results obtained from the multivariate covariance analysis showed a statistically significant difference between the experimental groups (i.e., holographic reprocessing group and dialectical behavioral therapy group) and the control group (F=132.141, P<0.001) regarding the cognitive flexibility and impulsivity. Moreover, according to the results of the Bonferroni test, the dialectical behavior therapy reduced the amount of impulsivity of depressed patients who attempted suicide more than the holographic reprocessing group (P<0.001). However, there was no significant difference between the dialectical behavioral therapy group and the holographic reprocessing group in terms of the level of cognitive flexibility (P>0.447).
 
Discussion & Conclusions: Both holographic reprocessing and dialectical behavior therapy can have remarkable effects on the treatment of depressive disorders. In addition, they are considered useful and can be employed as interventions in critical situations in which individuals attempt to commit suicide.
