The current study aimed to test the relationship between Internet addiction, loneliness, disordered sleep, and depression among a sample of Iranian university students at the undergraduate level considering the moderating role of gender. Compulsive Internet use was measured using the Internet addiction scale developed by Young. Depression was measured by the depression subscale of the SCL90 and feelings of loneliness were measured using the 3rd Persian version of the UCLA loneliness scale. Disordered sleep was assessed using the Persian version of the quality of sleep scale. Structural equation modelling was employed to test the mediation-moderation models. Primary results show that Internet addiction predicted depression, loneliness predicted disordered sleep and Internet addiction predicted disordered sleep. The roles of mediators have been proved in all models. Gender’s moderating role was not significant in any of the models.

目前的研究旨在考虑性别的调节作用，在本科水平的伊朗大学生样本中测试网络成瘾、孤独、睡眠障碍和抑郁之间的关系。强迫性互联网使用是使用 Young 开发的网络成瘾量表来衡量的。抑郁是通过 SCL90 的抑郁分量表来衡量的，而孤独感是使用 UCLA 孤独量表的第 3 版波斯语版来衡量的。使用波斯版本的睡眠质量量表评估睡眠障碍。采用结构方程模型来测试中介-调节模型。初步结果表明，网络成瘾预测抑郁，孤独预测睡眠紊乱，网络成瘾预测睡眠紊乱。中介者的作用已在所有模型中得到证明。在任何模型中，性别的调节作用都不显着。
