Objectives: The aim of the current study was to assess the psychometric properties of Online Game Addiction Inventory in under graduate students of Shahid Chamran University of Ahwaz. Method: Of all under graduate students in Shahid Chamran University of Ahwaz during 2014-15 academic year, 300 under graduate students from Shahid Chamran University were selected using multistage random sampling method. Samples completed Online Game Addiction Inventory and Young Internet Addiction Inventory. Cronbach’s alpha was used for examining the internal consistency of Online Game Addiction Inventory. The study tool was validated using construct, criterion and convergent validity. Results: Cronbach’s alpha was calculated 0.95 for this inventory under study. Construct validity confirmed and principal component analysis with Varimax rotation identified two factors, namely, ethical and mood problems and education and employment problems, respectively. These two factors accounted for 57% of the total variance. Independent t-test results revealed significant difference on the mean scores of online game addiction between the two addicted and normal groups. The results showed a significant difference in a rate of online game addiction between two groups. Convergent validity was tested by administration of Online Game Addiction Inventory and Young Internet Addiction Inventory concurrently; correlation coefficient was obtained 0.7. Conclusion: Current study results showed appropriate psychometric features of Online Game Addiction Inventory. Therefore, it can be used for examining online game addiction in Iran.

Objectives: Early maladaptive schemas are self-destructive emotional and cognitive patterns that have been formed at the beginning of development and are repeated in life. Since early maladaptive schemas can be the most predictive of addiction and social networking addiction is also considered as an injury or complication. This study aimed to determine the relationship between early maladaptive schemas and social network addiction among students.
Methods: This cross-sectional study was performed on 350 students of Semnan University of Medical Sciences. In this study, Yang’s Short Form Questionnaire and the questionnaire of social network s addiction based on mobile were used. Data were analyzed by the Chi-square test and logistic regression.
Results: There were 186 (53.2%) students who had social network addiction. Of them, 215 (61.4%) had at least one early maladaptive schema. The gender of the woman (OR=0.35, P=0.021), age over 21 years (OR=0.56, P<0.001), the formation of the schema of recognition (OR=0.54, P=0.01) and the formation of the schema entitlement (OR=0.47, P=0.002) with the reduction and the formation of the schema of social isolation / emotional inhibition (OR=2.94, P=0.006) was accompanied with increasing of the chance of being addicted to social networks.
Conclusion: The results showed that some of the individual characteristics and the formation of some of the schemas are associated with decreasing and increasing the chance of addiction to social networks.

Objectives: This study aims to assess the implementation of drug-related harm reduction programs in Iranian prisons and suggest solutions for their improvement.
Methods: This study was conducted in three steps. First, library method was used for collecting data from the central library of Iran’s Prisons, Security and Corrective Measures Organization. In the second step, performance indicators were extracted based on the results of first step and two researcher-made checklists were designed. Finally, a field visit and a semi-structured interview with the authorities involved in the treatment and harm reduction services were carried out.
Results: In most of prisons, drug-related harm reduction programs were underway. Despite a lack of human resources and budget at the beginning, the quality of measures was gradually increased and the attitude of authorities was improved. Methadone Maintenance Treatment and Triangular Clinics were the most common harm reduction programs, in addition to HIV and tuberculosis screening programs in collaboration with medical sciences universities. The program continued despite the change of officials.
Conclusion: Harm reduction programs are able to reduce infection diseases, self-harm and violent behaviors in prisons of Iran. Cultural programs along with other harm reduction programs, briefings and seeking support from the authorities can greatly help with continuation of the programs in prisons. By eliminating the shortage of manpower and redefining the security areas for ordinary prisoners, it will be possible to make better use of the facilities of universities and research centers.

Objectives Sex addiction is one type of behavioral addiction that is characterized by extreme fantasies and hard-to-control sexual behaviors. This disorder causes problems in the lives of affected people and their victims. The treatment is non-pharmacological and psychological, which are time-consuming and expensive. Short-term interventions are one of the ways to help these people. This study aims to evaluate the effectiveness of short-term clinical guidelines to treat sexual addiction disorder in affected individuals.
Methods This was a randomized clinical trial study with pre-test-post-test and follow-up. The studied population in this research included all people with sexual addiction disorder who live in Isfahan City, Iran. The statistical population was those who had the chance to be included in the study. These were individuals who were referred to outpatient and residential drug abuse treatment centers, psychiatric treatment centers, and sexual disorders treatment clinics. Using the balance block randomization method, 30 male subjects who were diagnosed with sex addiction disorder based on the cut-off point of the hypersexual behavior inventory (HBI) with a score of 53 and above were randomly divided into 2 intervention and comparison groups. The intervention group received ten 120-min therapy sessions held weekly. Because of the coronavirus pandemic, the treatment sessions had to be held virtually (Skype). The comparison group was put on hold so that they could benefit from the treatment if the guide was effective. Both groups completed the HBI three times. The first time was immediately before the treatment, the second time immediately after the intervention, and the third time 3 months later in the follow-up phase. The results were analyzed via repeated measures analysis of variance (RM-ANOVA) in the SPSS software, v. 22.
Results In the present study, there were 30 patients with a sexual addiction disorder, of which 15 were in the intervention group and 15 were in the comparison group (the Mean age of the participants was 26.4 years). The Mean scores of HBI in the intervention group in the pretest, post-test, and follow-up stages were 67, 49, and 57, respectively, while the mean scores of HBI in the comparison group were 64, 60, and 59 for the pretest, post-test, and the follow-up, respectively. Repeated measurement findings showed that this clinical guideline is effective in reducing participants’ sexual addiction symptoms (P‌<‌0.01). 
Conclusion Clinical guideline for short-term treatment of sexual addiction disorder is effective in reducing the symptoms of sexual addiction disorder. Using this method, which can be held online, and considering its short time and reduced cost of treatment, allows more people to benefit from it.

Objectives The present study aimed to determine the mediating role of smartphone addiction in the relationship between insecure attachment styles and phubbing among Iranian college students. 
Methods This is descriptive-correlational study using a structural equation modeling (SEM) approach. Participants were 615 college students (334 females, 281 males) with a mean age of 26.89±6.4 years, who were selected using a convenience sampling method from universities in Tehran, Iran. They completed online forms of Hazan & Shaver's attachment styles questionnaire, Sevari’s mobile phone addiction scale, and Chotpitayasunondh et al.’s generic scale of being phubbed.
Results The findings indicated a significant direct relationship between insecure attachment styles (avoidant and anxious) and smartphone addiction (P=0.001, β=0.5), and between insecure attachment styles and phubbing (P=0.012, β=0.16). Moreover, smartphone addiction mediated the relationship between insecure attachment styles and phubbing (P=0.005, β=0.366). 
Conclusion The college students with insecure attachment styles (avoidant and anxious) are more prone to smartphone addiction, which can lead to phubbing behaviors. Therefore, interventions should be used for fostering secure attachment styles and promoting healthy mobile use habits to reduce phubbing behaviors and thus enhance interpersonal relationships.
