While associations between abnormal eating behaviors and attitudes (AEBs) and addictive behaviors have been explored, existing research does not adequately control for confounding variables, leaving the possibility of spurious correlations. Therefore, this study aims to provide clearer insights by examining the relationships between anorexic and bulimic symptoms (i.e., drive for thinness and binge eating) and specific addictive behaviors, while controlling for psychological distress and multiple addictive behaviors.
Using a sample of 2,000 adult women, the participants self-reported their drive for thinness, binge eating, psychological distress, alcohol misuse, problematic internet use, compulsive shopping, and problem gambling.
Multiple regression analyses revealed that the drive for thinness was positively and negatively associated with alcohol misuse and compulsive shopping, and problem gambling, respectively. Binge eating was positively linked to problematic internet use and compulsive shopping. However, the effect sizes of these associations ranged from very small to small.
While the strength of the associations between AEBs and addictive behaviors among adult women, as reported in previous research, may reflect spurious correlations, the co-occurrence of different types of AEBs appears to be far more pronounced.
虽然已经探讨了异常饮食行为和态度（AEB）与成瘾行为之间的关联，但现有研究并未充分控制混杂变量，从而存在虚假关联的可能性。因此，本研究旨在通过考察厌食症和贪食症症状（即对瘦的追求和暴饮暴食）与特定成瘾行为之间的关系，同时控制心理困扰和多种成瘾行为，来提供更清晰的见解。
以2000名成年女性为样本，参与者自我报告她们对瘦的追求、暴饮暴食、心理困扰、酒精滥用、网络使用问题、强迫性购物和问题赌博情况。
多元回归分析显示，对瘦的追求分别与酒精滥用、强迫性购物和问题赌博呈正相关和负相关。暴饮暴食与网络使用问题和强迫性购物呈正相关。然而，这些关联的效应大小从非常小到小不等。
虽然先前研究报告的成年女性中AEB与成瘾行为之间关联的强度可能反映了虚假关联，但不同类型AEB的共现似乎更为明显。
