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.

Estimating the avoidable burden and population attributable fraction of human risk factors of road traffic injuries in iran: application of penalization, bias reduction and sparse data analysis.

The aim of this study was to prioritize human risk factors for preventive interventions by estimating the avoidable burden and population attributable fraction (PAF) of each risk factor using penalization and data augmentation method. To avoid the sparse data bias, Bayesian logistic regression via data augmentation methods, were used for multivariable analysis. Informative normal priors adopted from the studies were used for the studied human risk factors. Weakly informative log-f was used for the covariates. The population attributable fraction was calculated based on direct method. The comparative risk assessment methodology of the WHO was used to estimate the potential impact fraction for each risk factor. The most important human factors influencing the traffic-related deaths were overspeeding (OR = 9.6, 95% CI: 2.45-37.7), reckless overtaking (OR = 8.6, 95% CI: 1.82-40.7), and fatigue and drowsiness (OR = 6.7, 95% CI: 1.79-25). The total PAF for the all studied risk factors was about 56% (PAF = 0.567, 95% CI: 0.37-0.7). The greatest avoidable burden was related to fatigue and drowsiness, overspeeding, and not fastening seatbelt. By considering the high contribution of human risk factors in occurrence of fatal traffic injuries appropriate legislation and prevention programs for these risk factors would decrease half of such deaths.

Comparison of trauma-focused cognitive behavioral therapy and theory of mind: Improvement of posttraumatic growth and emotion regulation strategies.

BACKGROUND: Assessing various therapeutic methods with the intention to decrease the problems relevant to abused children is of high significance. Accordingly, the present study seeks to compare the effectiveness of trauma-focused cognitive behavioral therapy (TF.CBT) with an emphasis on the theory of mind on posttraumatic growth and emotional regulation strategies in abused children. MATERIALS AND METHODS: This quasi-randomized clinical trial study was done on 39 abused children who referred to welfare organization centers in Ahvaz - Iran. After randomized allocation, the TF. CBT and theory of mind method were implemented for two groups. Before and after the interventions, posttraumatic growth and emotional regulation strategies were assessed with using Kilmer's posttraumatic growth inventory and Garnefski emotional regulation questionnaire. RESULTS: The study findings indicated that the mean of the posttraumatic growth and adaptive and maladaptive emotional regulation strategies in the TF.CBT group was significantly higher than that of other study groups (P < 0.001). CONCLUSION: TF.CBT can lead to increased levels of posttraumatic growth and improve emotional regulation strategies in abused children. Theory of mind method can also be effective in improving emotional regulation strategies.

Trauma-focused cognitive behavioral therapy a clinical trial to increase self-efficacy in abused the primary school children.

BACKGROUND: Child abuse and violence toward children has become a complex phenomenon in nowadays societies leaving hurt children with numerous complications such as lowered self-efficacy. Hence, this study was conducted to assess the effect of trauma-focused cognitive behavioral therapy (TF-CBT) in physically abused children self-efficacy. MATERIALS AND METHODS: This study was a randomized clinical trial. From this statistical population of all abused children aged 9-12 in Kermanshah in 2016-2017, 40 were divided into intervention and control groups randomly. Tools used in this study were Maurice self-efficacy questionnaire and child abuse questionnaire. Data analysis was done using Chi-square test, paired t-test, and independent t-test. RESULTS: It was revealed that the mean difference between two groups was not meaningful before intervention. After TF-CBT in intervention group, self-efficacy mean scores of social (17.95 vs. 24.20) and emotional (15.05 vs. 19.05) domains showed meaningful differences, whereas academic self-efficacy mean score did not change significantly (14.10 vs. 14.65) (P < 0.086). In control group, social (16.20 vs. 15.55), emotional (13.90 vs. 14.35), and academic (13.40 vs. 13.90) mean self-efficacy scores were not of significant difference (P > 0.001). CONCLUSIONS: TF-CBT can be used as an appropriate therapy intervention to improve social and emotional self-efficacy in abused children.

Cognitive factors related to drug abuse among a sample of Iranian male medical college students.

BACKGROUNDS: Drug abuse is one of the most serious social problems in many countries. College students, particularly at their first year of education, are considered as one of the at risk groups for drug abuse. The present study aimed to determine cognitive factors related to drug abuse among a sample of Iranian male medical college students based on the social cognitive theory (SCT). METHOD: This cross-sectional study was carried out on 425 Iranian male medical college students who were randomly selected to participate voluntarily in the study. The participants filled out a self-administered questionnaire. Data were analyzed by the SPSS software (ver. 21.0) using bivariate correlations, logistic and linear regression at 95% significant level. RESULTS: Attitude, outcome expectation, outcome expectancies, subjective norms, and self-control were cognitive factors that accounted for 49% of the variation in the outcome measure of the intention to abuse drugs.  Logistic regression showed that attitude (OR=1.062), outcome expectancies (OR=1.115), and subjective norms (OR=1.269) were the most influential predictors for drug abuse. CONCLUSIONS: The findings suggest that designing and implementation of educational programs may be useful to increase negative attitude, outcome expectancies, and subjective norms towards drug abuse for college students in order to prevent drug abuse.
