relation of brain behavioral systems, D personality type, anger and hostility in people with gum disease

Gum disease is a chronic bacterial infection that affects the gum structures. Given the importance of psychological factors and their impact on physical condition such as gum disease, the aim of this study was to investigate D personality type, brain behavioral systems and anger and hostility in people with gum disease. In this causal-comparative study, 50 women with and 50 women without gum disease [age range from 14 to 37] were selected using purposive sampling method and completed the questionnaires of multidimensional anger [Sigel, 1986], D personality type scale, Behavioral inhibition/activation system. MANOVA was used for data analysis. Data analysis showed that groups had significant differences in behavioral inhibition system, behavioral activation system and its components [response to drives, fun seeking, reward responsiveness], D personality type and its components [negative affectivity, social inhibition], anger-arousal, hostile attitude and anger-in [p<0.05], but there were no differences in anger arousing situations and anger-out between them. People with gum disease score higher in BIS, and lower in BAS than normal people, and score higher in D personality type and its components, anger-arousal, hostile outlook, and anger-in. This suggests that psychological factors play a significant role in developing and continuing gum disease and possibly other psychosomatic disorders. So this study focuses on the decisive role of psychological treatments in prevention and promotion of physical and psychological health of people

Predicting obsessive-compulsive disorder on the basis of emotion regulation and anxiety sensitivity

Emotion regulation and anxiety sensitivity are two psychological components which play important roles in causing anxiety disorders. This study aims at predicting the Obsessive-Compulsive Disorder [OCD] based on the emotion regulation and anxiety sensitivity in university students. In this descriptive correlation study, a total of 317 students of University of Mohaghegh Ardabili were selected using available sampling method in 2010-2011 academic year and they were asked to fill out the obsessive-compulsive inventories designed for emotion regulation and anxiety sensitivity. The results of regression analysis showed that reappraisal and anxiety sensitivity are the best indicators of OCD in students. The results indicated that the reappraisal and anxiety sensitivity play a significant role in predicting OCD in students

[Early maladaptive schemas and parenting styles of students who have failed in love with and without the clinical syndrome]

The aim of this study was to compare the early maladaptive schemas and parenting styles among students with love failure, with or without the clinical syndrome. Using purposive sampling and based on Beck Depression Inventory-II [BDI-II], General Health Questionnaire-28 [GHQ-28], and the Millon Clinical Multiaxial Inventory-III [MCMI-III] 30 students with love failure and clinical syndrome and 30 students with love failure and without clinical syndrome were selected from University of Tabriz, and completed Young's Schema Questionnaire-Short Form [YSQ-SF] and Schaefer Family-Parenting Environment [SFPE]. Data were analyzed using multivariate analysis of variance [MANOVA]. There was a significant difference between the groups in the early maladaptive schemas and parenting styles [p<0.05]. We can predict the severity of clinical signs in romantic relationship failure on the basis of early maladaptive schemas and family of origin environment and accordingly schema therapy approach can be used in clinical and counseling centers to help these people

impairing role of stress on autobiographical memory reconsolidation

Despite some studies indicating improving role of stress on memory consolidation, very few animal and human studies show that stress impairs reconsolidation of memories. This study aimed to determine the effect of stress on autobiographical memory reconsolidation. The present study was done with an experimental method [Solomon Four-Group design]. The statistical society of this study was all undergraduate female students in 2009-2010 academic year at Tabriz University. Forty students were selected using random cluster sampling, and we ensure about their physical and mental health by GHQ-28 and interview. Tools for this study were cueing autobiographical memory test, SECPT [for raising blood pressure and stress induction], autobiographical memory test, PANAS and general health questionnaire [GHQ-28]. MANOVA was used for data analysis by SPSS-17. The results show that stress after activation of memory impairs memory for neutral events [p<0.001], while there was no such effect on the memory for emotional events [p>0.05]. None of stress and memory activation alone had effect on memory performance [p>0.05]. These findings indicate that stress impairs autobiographical memory reconsolidation, which is opposite to its effects on memory consolidation, so it supports the view that consolidation and reconsolidation are separate process.
