Introduction: Online gaming addiction is a growing global concern and is detrimental to mental health among adolescents. The present study was conducted aiming to predict the structural relationship model of online game addiction based on Deviant Peer Affiliation with the mediating role of maladaptive cognitions and social skill deficits.Materials and Methods: The intended research was structural equation correlation. Its statistical population included all male students of the second year of high school students studying in the public schools of Ardabil city in the academic year of 2023.A sample of 208 participants was selected using convenience sampling method who completed the questionnaires of addiction to online games. The obtained data were analyzed using smart pls4 software.Results: The results showed that Deviant Peer Affiliation has a direct and significant effect on addiction to online games, and the indirect effect of Deviant Peer Affiliation on addiction to online games was confirmed through the mediation of maladaptive cognitions and social skill deficits. The model had a good fit based on the goodness of fit indices.

Background & Objectives: According to the increasing opioids abuse between women and pathophysiological effects of chronic exposure of opioids on mothers which might indirectly affect their offspring, herein, consequences of chronic morphine consumption and its withdrawal before the gestation was investigated on spatial memory, avoidance memory and vulnerability to morphine intake in offspring of first generation.
Materials & Methods: Twelve female Wistar rats were randomly divided into two groups. Morphine mothers group received morphine solution (0.4 mg/ml) for two months. Control mothers group received tab water. One month after stopping morphine consumption, mating was occurred. After the parturition, offspring was divided in separated male and female groups and was used as the target groups of the study. Spatial memory through Water Maze, avoidance memory through Shuttle Box and vulnerability to morphine intake through voluntary consumption of morphine solution were investigated.
Results: Mean of morphine solution consumption in male and female offspring of morphine mothers was significantly higher in compare to male and female offspring of control mothers (P<0.05). Results of learning in Water Maze revealed that male offspring of morphine mothers significantly spent more time and distance to find the platform in compare with male offspring of control (P<0.01). Also, in retention test, male offspring of morphine mothers cross the location of platform significantly fewer than male offspring of control (P<0.001). There was no significant differences in avoidance learning between experimental groups (P<0.05).
Conclusion: Our study revealedchronic morphine consumption before the gestation causesdamage of spatial memory in male offspring and also increases vulnerability to opiate intake of male and female offspring.
