Background: The aim of this study was to compare noise sensitivity (NS) in schizophrenic individuals with/without hallucinations and healthy individuals. Procedure: A retrospective (causal–comparative) study was conducted in three groups: (i) A group of individuals with schizophrenia and auditory hallucinations (14 participants), (ii) a group of schizophrenic individuals without auditory hallucinations (14 participants) selected by purposive sampling and (iii) a control group (19 participants) selected by convenience sampling. Schutte’s Noise Sensitivity Questionnaire was used to measure NS. Analysis of Variance and Kruskal–Wallis tests were applied to compare the three groups. All the analyses were done using SPSS-20. Results: ANOVA results indicated that the groups were significantly different in terms of NS (p

Some psychiatric disorders are mostly overlapping and measures for facilitating differential profiles play a key role in the identification of a disease, course, prognosis, and management. This systematic review and meta-analysis aimed to (i) explore the association between the components of temperament and character model and three overlap psychiatric diagnoses including avoidant personality disorder (APD), schizoid personality disorder (SPD), and social anxiety disorder (SAD) and (ii) provide differential profiles for each of these disorders. The literature search was performed on 7 international scientific databases for all articles published in English, January 1990-June 2019. The pooled effect sizes were obtained using the correlation coefficients or the standardized mean differences between cases with SAD and healthy controls by the random-effects method. Fifteen correlational studies for APD and SPD and eight case–control studies for SAD met the criteria for entering meta-analysis. All three disorders were positively associated with harm avoidance (HA) and negatively associated with novelty seeking (NS), self-directedness (SD), and cooperativeness. APD and SPD were also negatively associated with reward dependence (RD). The differential profiles are as follows: NS (APD < SAD), HA (APD > SPD, SAD), RD (SPD < APD < SAD), SD (APD < SPD, SAD), cooperativeness (APD, SPD < SAD), and self-transcendence (ST: APD > SPD, SAD). It seems that HA, SD, and cooperativeness are the common core of these three diagnostic categories. More extreme tendencies in NS and RD, along with ST with a lower possibility, are the main traits in the differential profiles.

BACKGROUND: Irritable bowel syndrome (IBS) is one of the most common gastrointestinal diseases, and obsessive–compulsive disorder (OCD) is one of the main causes of this disease. The present study was aimed to investigate the prevalence of OCD in patients with IBS. MATERIALS AND METHODS: The present research is a cross-sectional survey study. The research sample included 120 patients with IBS who referred to Imam Reza Hospital and gastrointestinal clinics in Kermanshah (Iran) in the 3 months of April, May, July in 2019 that were selected using the census sampling method, and demographic information, clinical and medical records were collected. Data analysis was performed using frequency, percentage, and Chi-square. RESULTS: Among the patients who were studied, 58 of them (48.3%) were women and 62 (51.7%) were men, the results showed that the prevalence of OCD in patients with IBS was 14.96 and the symptoms of washing, checking, skepticism and slowness-repetition had the highest prevalence, respectively. These symptoms were more common in women than in men. There was also a significant relation between OCD prevalence in patients with IBS and with female gender, age-range 30–21 years, single, and history of OCD in the patient's immediate family and close relatives (P < 0.05), but there was no significant relationship between OCD prevalence in patients with IBS and level of education, occupation, income status, and place of residence CONCLUSION: Due to the high prevalence of OCD in patients with IBS, the interaction of gastroenterologists and psychiatrists to treat irritable bowel syndrome is very important.

INTRODUCTION: Given the close relationship between life style and mental health and the importance of students as valuable human resources, the present study aimed at determining the relationship between life style and mental health among medical students in Kermanshah. METHODS: This is a descriptive-correlational study that was conducted in 2018. The study involved 200 medical students. The sampling method was convenience sampling. Demographic questionnaire, general health questionnaire, and life style questionnaire were used for data collection. The data were analyzed Pearson's correlation test and regression analysis. The significance level was considered 0.05. RESULTS: The mean mental health score of the students was 25.43 ± 13.02 (2 points higher than the cutoff point of this test). The life style of 59.5 students was moderate. The results showed that all life style subscales had a negative significant relationship with the total mental health score and all its subscales (P < 0.05). Among the life style subscales, the highest relationship and predictive power to mental health were obtained for psychological health, social health, sport and fitness, and environmental health (R2 = 0.48, P < 0.001). CONCLUSION: According to the results, the life style of most medical students in the final year of Kermanshah University of Medical Sciences was moderate. Further, the students had a better life style, and they had higher mental health. Therefore, considering the vital role of medical students in providing and promoting community health, the need for more detailed planning and interventions to improve their life style and mental health is essential.
