Over the past two decades, many problematic/excessive behaviours have increasingly been conceptualized as addictions due to their similarity with more traditional psychoactive substance addictions. The primary aim of the present study was to simultaneously examine the factor structure of three psychoactive substance addictions (alcohol use, cigarette smoking, and substance use) and seven behavioural addictions (sex, social media use, shopping, exercise, online gambling, internet gaming, and internet use), using exploratory factor analysis (EFA; N = 481) and confirmatory factor analysis (CFA; N = 487). A total of 968 participants completed an online survey including ten psychometric scales assessing the ten different potentially addictive behaviours. EFA supported a two-factor solution, with different factors for the psychoactive substance and behavioural addictions (excluding exercise addiction). CFA supported the two-factor model in a separate sample. There was good support for the concurrent and discriminant validities of the CFA latent factors and the reliability of the behavioural latent factor in the two-factor CFA model. While there was support for the concurrent and discriminant validities of the psychoactive substance latent factor, there was insufficient support for its reliability. The taxonomic, theoretical, and clinical implications of the findings are discussed.
在过去的二十年中，由于与更传统的精神活性物质成瘾相似，许多有问题的/过度行为越来越被概念化为成瘾。本研究的主要目的是使用探索性因素分析（EFA；N=481）和验证性因素分析（CFA；N=487）同时检验三种精神活性物质成瘾（酒精使用、吸烟和物质使用）和七种行为成瘾（性、社交媒体使用、购物、锻炼、在线赌博、网络游戏和互联网使用）的因素结构。共有 968 名参与者完成了一项在线调查，其中包括评估十种潜在成瘾行为的十种心理测量量表。EFA 支持双因素解决方案，精神活性物质和行为成瘾（不包括锻炼成瘾）有不同的因素。在另一个样本中，CFA 支持双因素模型。在双因素 CFA 模型中，CFA 潜在因素的同时和判别有效性以及行为潜在因素的可靠性得到了很好的支持。虽然对精神活性物质潜在因素的同时和判别有效性有支持，但对其可靠性的支持不足。讨论了研究结果在分类学、理论和临床方面的意义。
