The validity and reliability of Persian version of smartphone addiction questionnaire in Iran.

BACKGROUND: Smartphone addiction is one of the most important forms of technology addiction that has attracted the attention of all countries around the world. Many studies have been conducted in Iran on cellphone addiction among different groups. There is a necessity to have a native scale for measuring smartphone addiction in particular. Therefore, this study aimed to localize the smartphone addiction questionnaire in Iran (in the Persian language). METHODS: To assess the validity and reliability of the Persian version of the smartphone addiction scale (SAS), the questionnaire was first provided based on the standard back-translation method. Next, content validity ratio (CVR), content validity index (CVI), and face validity was evaluated for translated questionnaire. After making the necessary changes, the questionnaire was given to the community samples and was then reviewed using confirmatory factor analysis of questions grouping. Finally, the reliability of the questionnaire was investigated by the test-retest method. RESULTS: The CVR and CVI values of all questions were within the acceptable range. Only some of the questions in the original SAS version titled Twitter and Facebook were changed to Instagram and telegram according to experts. Internal consistency and concurrent validity of the questionnaire were confirmed by Cronbach's alpha of 0.951. The mean correlation coefficient between the responses of the subjects, who received the questionnaire twice, was 0.946 (0.938-0.954). The grouping of questions in the subscales was changed from the original SAS version because the fitting indexes, obtained from the confirmatory factor analysis test (for example CMIN/DF greater than 5 units and RMSEA of approximately 0.07), were not acceptable. CONCLUSION: The results showed that the Iranian version of the cellphone addiction questionnaire can be used as a valid, with minimal modification, tool for determining the level of smartphone addiction among Persian speakers.

A Systematic Review on the Epidemiology of Pediatric Burn in Iran.

Burn is the most common pediatric injuries all over the world. The aim of this study was to study the epidemiology of burn in under 15-year-old Iranian children by applying a systematic review. The related articles published before 2016 have been gathered from international databases by using the keywords in term of pediatric burns such as ScienceDirect, PubMed, Iranmedex, Google Scholar, Embase, Magiran, and SID. The checklists of STROBE have been applied to evaluate the quality of the reviewed data. A total of 35 relevant studies were extracted and evaluated. In most studies, the incidence of pediatric burns in male patients was more than female patients by 9.5 to 50 cases in 100,000 per children. Mortality rate of pediatric burn was between 1.7 and 18.5%. The most common cause of pediatric burn was hot water or other hot liquids. Pediatric burn in urban areas was higher and the highest number of pediatric burns occurred at home. Burn is considered as one of the major incidents related to children's health that required planning to reduce its incidence, especially in the lower age groups as well as male patients who are more active and susceptible to burn.

Evaluating Effect of Albendazole on Trichuris trichiura Infection: A Systematic Review Article.

BACKGROUND: The aim of the study was assessment of defaults and conducted meta-analysis of the efficacy of single-dose oral albendazole against T. trichiura infection. METHODS: We searched PubMed, ISI Web of Science, Science Direct, the Cochrane Central Register of Controlled Trials, and WHO library databases between 1983 and 2014. Data from 13 clinical trial articles were used. Each article was included the effect of single oral dose (400 mg) albendazole and placebo in treating two groups of patients with T. trichiura infection. For both groups in each article, sample size, the number of those with T. trichiura infection, and the number of those recovered following the intake of albendazole were identified and recorded. The relative risk and variance were computed. Funnel plot, Beggs and Eggers tests were used for assessment of publication bias. The random effect variance shift outlier model and likelihood ratio test were applied for detecting outliers. In order to detect influence, DFFITS values, Cook's distances and COVRATIO were used. Data were analyzed using STATA and R software. RESULTS: The article number 13 and 9 were outlier and influence, respectively. Outlier is diagnosed by variance shift of target study in inferential method and by RR value in graphical method. Funnel plot and Beggs test did not show the publication bias (P=0.272). However, the Eggers test confirmed it (P=0.034). Meta-analysis after removal of article 13 showed that relative risk was 1.99 (CI 95% 1.71 - 2.31). CONCLUSION: The estimated RR and our meta-analyses show that treatment of T. trichiura with single oral doses of albendazole is unsatisfactory. New anthelminthics are urgently needed.
