Evaluating the Effect of Family-Centered Intervention Program on Care Burden and Self-Efficacy of Hemodialysis Patient Caregivers Based on Social Cognitive Theory: A Randomized Clinical Trial Study

Background Caregivers of hemodialysis patients spend a large amount of time providing care to these patients while tolerating fatigue and stress. This study evaluated a family-centered empowerment program on the care burden and self-efficacy of hemodialysis patient caregivers based on social cognitive theory. Methods In this randomized clinical trial, 70 family caregivers of hemodialysis patients in Isfahan, Iran, were selected and randomly allocated to intervention and control groups, in 2015–2016. Two questionnaires were used to collect the family caregivers’ characteristics, care burden, and self-efficacy, and patients’ negative and positive outcomes expectancies. Data were analyzed using SPSS before, immediately after, and 2 months after the intervention. Results There was no significant difference in the mean scores of care burden, positive outcomes expectancies, negative outcomes expectancies, and self-efficacy between the two groups before the intervention. However, there were significant differences in the post-test and follow-up data analyses (P<0.05). Conclusion Given the degenerative nature of chronic kidney disease, it can be considered as a source of long-term and chronic stress for caregivers. Therefore, by implementing an empowerment program, caregiving behaviors can be improved, positive outcomes expectancies can be increased, and negative outcomes expectancies can be reduced.

A Broadband Out-of-Phase Gysel Power Divider Based on a Dual-Band Circuit With a Single Fixed Isolation Resistor

Based on the double-sided parallel-strip lines with an inserted conductor as a virtual ground, a high power divider with dual-band/broadband response and frequencyindependent 180 degree phase difference between the output ports is implemented in this paper. The circuit topology employs a single commercially available external isolation resistor as well as moderate line impedances (15–100 ohm), making it suitable for high-power applications. Precise closed-form design equations on the basis of even- and odd-mode analysis are derived. In addition to the wide range of frequency band ratios from 1 to 2.65, broadband response is also obtained by selecting the proper value of frequency band ratios. To substantiate the design equations and theory, a circuit with 2:1 frequency ratio and 84.5% bandwidth referring to 16 dB isolation and 12 dB return loss values is developed. To the authors’ knowledge, this is the widest bandwidth reported for out-of-phase high power dividers

The effectiveness of assertiveness training on the levels of stress, anxiety, and depression of high school students

Background: Adolescence is a transition period from childhood to early adulthood. Because of the immense pressure imposed on adolescents due to the complications and ambiguities of this transition, their level of excitement increases and sometimes it appears in the form of sensitivity and intense excitement. Objectives: This study aimed at determining the effectiveness of assertiveness training on the levels of stress, anxiety, and depression of high school students. Materials and Methods: This quasi-experimental study was conducted on high school students of Isfahan in academic year 2012 -13. A total of 126 second grade high school students were collected according to simple random sampling method and divided into two groups: experimental with 63 participants and control with the same number. Data gathering instruments included a demographic questionnaire, Gambill-Richey assertiveness scale, and depression anxiety stress scales (DASS-21). Assertiveness training was carried out on the experimental group in 8 sessions; after 8 weeks, posttest was carried out on both groups. Statistical tests such as independent t test, repeated measures ANOVA, Chi-square test, and the Mann-Whitney test were used to interpret and analyze the data. Results: The Chi-square and Mann-Whitney tests did not show significant statistical differences between the two groups in terms of demographic variables (P = 0.05). Repeated measures ANOVA showed no significant difference between the mean scores for assertiveness before (100.23 ± 7.37), immediately after (101.57 ± 16.06), and 2 months after (100.77 ± 12.50) the intervention in the control group. However, the same test found a significant difference between the mean score for assertiveness in the experimental group before (101.6 ± 9.1), immediately after (96.47 ± 10.84), and 2 months after (95.41 ± 8.37) implementing the training program (P = 0.002). The independent t test showed no significant difference in the mean score for anxiety and stress between two groups before the assertiveness training program; however, 2 months after the intervention, the mean score for anxiety in the experimental group was found significantly lower than the control group. As for the mean score for depression, the independent t test showed no significant difference between two groups before training; however, despite the decrease in the mean scores for depression in the experimental group following the intervention, the difference was not significant (P = 0.09). Conclusions: The results of the current study show that conducting assertive training in high school students decreases their anxiety, stress, and depression. Given that high school years are among the most sensitive stages of one’s life plus the fact that conducting such training programs besides their safe and low cost nature are effective and practical, it is highly recommended that such programs be carried out among high school adolescents. © 2016, Iranian Red Crescent Medical Journal

The highest prevalence of disturbances was depression and then sleeps disorders, anxiety, physical and psychological, and social dysfunction. Factors such as marital status and employment status were significantly related to students' general health status. In this study there was a significant negative correlation between general health and the average score of students (P= 0.001). Senior students (forth-year), has the highest grade point Average and third-year students, with the best general health status. Conclusions: The results of this study showed that, students with high academic performance in comparison to other students had better genaral health. Therefore, it should be more concerned to plan the high quality education for promoting life skills and designing communication programs for increase the support activities of families and authorities for psychological assessment and promote their general health

Prevalence of obsessive-compulsive disorder in Iran

BACKGROUND: Estimates of the annual prevalence for Obsessive Compulsive Disorder (OCD) were consistent across the international sites range, 1.9% – 2.5%. The nine population surveys, which used Diagnostic Interview Schedule, estimated a six-month prevalence of OCD ranging from 0.7% to 2.1%. This study performed in order to determine the prevalence of OCD in a population-based study among Iranian adults aged 18 and older and to study the association of them with factors such as sex, marital status, education, type of occupation and residential area. METHODS: A cross-sectional nationwide epidemiological study of the Iranian population aged 18 and older was designed to estimate the prevalence of psychiatric disorders and their association with the above mentioned factors. 25180 individuals were selected and interviewed through a randomized systematic and cluster sampling method from all Iranian households. Schedule for Affective Disorders and Schizophrenia (SADS) and Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria were used in diagnosis of OCD. 250 clinical psychologists interviewed the selected subjects face to face at their homes. RESULTS: The prevalence of OCD in Iran is 1.8% (0.7% and 2.8% in males and females; respectively). 50.3% of the survey sample were men, 49.9% women, 29.1% single, 67.45% married, 0.4% separated or divorced, 2.5% widow/widower and 4% undetermined. All of the above-mentioned factors were examined in the univariate and multivariate logistic regression models. Although the data did not fit the models well, but in univariate models, sex, the category "single" of marital status, age, the categories "business" and "housewife" and residential areas showed significant effect adjusting for the factors, but the models didn't fit the data properly. CONCLUSION: The study suggests that the prevalence of OCD is not rare in the community of Iran and is within the range of other countries. Similar to prior studies in other communities, OCD is more common in females than males

Identification of Network Physical Properties in Simulation of Flow Through Porous Media Using Network Model

Simulation of flow phenomena in porous media occur in many areas of sciences and engineering. It has wide applications in a variety of disciplines including water resources engineering, environmental and chemical engineering, petroleum engineering, and groundwater hydrology. Both theoretical and experimental studies conducted to further our understanding of flow and transport phenomena in porous media are based on Darcy and Forchheimer constitutive equations. In recent years, a few investigators considered converting original porous media into a 2-D and/or 3-D networks to address challenging and complex issues in porous media. Such a network can be conceptualized as consisting of a series of pore bodies and throats. Pore body comprises the void between grains and throat represents the channel connecting two pore bodies. The basic question is how to choose throat’s length and size. In this study, two porous media of uniform size (i.e., spherical balls) but different diameters were constructed in the hydraulic laboratory of school of engineering, Shiraz University. A methodology is developed to convert each porous media into an equivalent network and the resulting network is subjected to rigorous computer simulation. Validity of such conversion is achieved via triggering and monitoring the two actual porous media in the laboratory. For this purpose, the equivalent network of first porous media is calibrated Preprint submitted to Journal of Water and Wastewater Engineering 5 May 2008 for pipe roughness using three different resistance equations. As both porous media have the same surface roughness characteristics, the equivalent network of second porous media is solved in a forward manner with different upstream heads using roughness coefficient obtained from the first porous media. Observed and simulated water surface profiles and outflow discharges from the second porous media are compared and contrasted to each other. Results show a good agreement between predicted values of the network model and experimental data obtained in the laboratory
