Background and Aim: Nowadays, prioritizing problems and distribution of resources is determined according to the basic needs of the individuals in the population. Based on the study done by researchers in Tehran University of Medical Sciences School of Public Health in Golhesar Village, Tehran, taking action about "drug abuse" was ranked by the community as the first priority. Therefore, the present study aimed to estimate the size of the population of drug abusers using the network expansion method.

Materials and Methods: This cross-sectional study was conducted on a purposive sample of 320 persons 15-65 years old. The study included two parts: 1. estimation of the social network based on 32 population subgroups using the frequency of network expansion approach; 2. estimation of the size of the hidden population. The relevant correction coefficients were used for adjusting errors usually observed in this method.                                                                                                                                                    Results: The mean of the social network was 160.79±16.68) 95% CIs: 128.78-194.30.(The frequencies of cigarette smoking, hookah smoking, alcohol consumption, opium use, meth use, crack use, heroin use, injecting drugs and ecstasy were 103.43, 88.25, 96.9, 76.46, 69.37, 30.03, 20.48, 7.36, and 4.23 per 1000; respectively. The percentage of drug abusers was higher among men.

Conclusion: As compared to results of previous reports, the size of drug abuser population in Golhesar Village is currently higher. In order to solve this problem an appropriate action plan should be implemented by the planners and policy-makers in partnership with community members.

Background and Aim: Communication is one of the oldest and greatest human achievements underlying our social life. Available literature show factors such as self-esteem, interpersonal skills, establishing desirable communication, goal setting and determining individual values have effective roles in the prevention and reduction of susceptibility to behavioral abnormalities and mental disorders (anxiety, depression, etc.), as well as in the promotion of mental health. The objective of this study was to determine associations between communication skills and mental health in Mashhad University of Medical Sciences (MUMS), Mashhad, Iran.

Methods and Materials: This was a cross-sectional analytical study conducted in 2011. The statistical population was all the MUMS students. A sample of 210 students was selected by stratified sampling and signed an informed consent. Data were collected using Communication Skills and General Health Questionnaires and analyzed using the SPSS 16 software, the statistical tests being Kruskal-Wallis, Mann-Whitney U and Chi-square. In all tests the significance level was 5%. To determine correlations between the variables the Spearman coefficient was used.

Results: The findings showed that 130 of the 210 students (61.9%) were suspected of having a mental disorder. Based on the Spearman correlation coefficient there were no statistically significant relationships between mental health and age (p=0.727) or skills such as listening (p=0.653), understanding verbal and nonverbal messages (p=0.857), awareness of the communication process (p=0.626) and assertiveness (p=0.477). However, a significant correlation was observed between mental health and emotion control skill (p=0.010). Furthermore, the Spearman correlation coefficient indicated no relationships between communication skills and age (p=0.228) or social dysfunction (p=0.074), while significant inverse correlations were found between communication skills and anxiety (p=0.043), physical symptoms (p=0.049) and depression (p=0.049). According to Mann-Whitney test no significant relationships were observed between communication skills and field of study (p=0.806), level of education (p=0.406), sex (p=0.404), place of residence (p=0.277), marital status (p=0.875) or employment status (p=0.274), but significant relationships did exist between mental health and sex (p=0.006), field of study (p=0.036)r and marital status (p<0.001). Finally, no significant correlations were found between mental health and level of education (p=0.080), place of residence (p=0.951) or employment status (p=0.978).

Conclusion: Based on the findings of this study, in an attempt to promote the mental health of the students it is recommended to make psychological assessments of the students, provide consultative services to them, and organize communication skills educational workshops for them.
