Aims: We investigated gender differences among adolescents in quality of sleep, psychophysiological problems, dream frequency, emotional states, and personality traits and also if the effect of quality of sleep on psychophysiological problems, dream frequency, emotional states, and personality traits was moderated by gender. Method: High school pupils (n1 = 155, n2 = 142, and n3 = 325) responded to the Uppsala Sleep Inventory, the Positive Affect Negative Affect Schedule, Beck’s Depression Inventory, the Type A-Personality Scale, and the Temperament and Character Inventory. Gender differences were investigated using Multivariate Analyses of Variance and moderation using multi-group Structural Equation Modeling. Results: Girls scored higher in major sleep problems, difficulties falling asleep, night awakenings, psychophysiological problems, dream frequency, negative affect, depression, stress, and Type A-personality. Boys scored higher in novelty seeking, harm avoidance, and persistence. Girls’ quality of sleep was related to their psychophysiological problems, dream frequency, positive affect, negative affect, stress, novelty seeking, reward dependence, persistence, and self-directedness. Boys’ quality of sleep was related to their psychophysiological problems, negative affect, stress, Type A-personality, novelty seeking, harm avoidance, reward dependence, and self-directedness. Conclusion: Girls showed the unhealthiest sleep-psychophysiological-emotional-personality profile. For both genders, good quality of sleep or “beauty sleep” might result in less psychophysiological problems, less negative affect, less stress, less novelty seeking, and less self-directedness. However, for boys, “sleeping beauty” comprises less Type A-behaviour, ss harm avoidance, and more reward dependence; while for girls “sleeping beauty” comprises less frequency of vivid dreams, more positive affect, less reward dependence, and more persistent behaviour.

The purpose of the present study was to examine the relationship between psychological factors , Erectile Dysfunctional ( E D ) and quality of life ( Q O L) before and after Coronary Artery Bypass Graft ( C A B G ) and Percutaneous Transluminal Coronary Angioplasty ( P T C A ) procedures , in an Iranian sample of cardiovascular patients . To do so, one hundred ninety patients scheduled for CA BG and PTCA operations were selected and administered relevant questionnaires a day before the surgery . Subsequently , the same patients filled out the same questionnaires two months following the procedure . Data analysis showed an increase in Qol while revealing a decline in men’s sexual functioning after the PT CA procedure although no change was observed in women . Also , an improvement in psychological status of all patients was observed following both revascularization procedures .

Background: The present study aimed to examine the effectiveness of mindfulness-based stress reduction training on negative emotions with gastrointestinal disorders. Method: A quasi-experimental study was designed with pretest-posttest using a control group. The study sample consisted of 30 male patients (referred to internal experts and admitted to Abbasi Hospital of Miandoab in 2016) with gastrointestinal disorders (Irritable Bowel Syndrome, peptic ulcer, and duodenal ulcer) based on diagnostic criteria (ROME-III) who were selected by purposive sampling method. The patients were randomly divided into two experimental and control groups. After performing the pretest using Depression, Anxiety, and Stress Scales (DASS), the experimental group received mindfulness-based stress reduction intervention during the eight sessions of one and a half hour, while the control group received no psychological intervention; and after the end of the sessions, the posttest was performed for both groups using the same tools. The collected data were analyzed through covariance analysis (ANCOV) by using SPSS-18 software. Results: The mean scores of negative emotions rates of experimental group significantly decreased after receiving the mindfulness-based stress reduction intervention (P
