A new measure to assess friendship jealousy in the context of social media was developed. This one-factor, seven-item measure was psychometrically sound, showing evidence of validity and reliability in three samples of North American adults (Study 1, n = 491; Study 2, n = 494; Study 3, n = 415) and one-, two-, and three-year stability (Study 3). Women reported more social media friendship jealousy than men (Studies 2 and 3) and younger women had the highest levels of social media friendship jealousy (compared with younger men and older men and women; Study 2). Social media friendship jealousy was associated with lower friendship quality (Study 1) and higher social media use and trait jealousy (Study 2). The relation between social media friendship jealousy and internalizing symptoms indicated positive within time associations and longitudinal bidirectional relations (Study 3). Specifically, social media friendship jealousy predicted increases in internalizing problems, and internalizing problems predicted greater social media friendship jealousy accounting for gender and trait levels of social media friendship jealousy and internalizing problems. Anxious and depressed adults may be predisposed to monitor threats to their friendships via social media and experience negative consequences because of this behavior. Although social media interactions can be associated with positive well-being and social connectedness, our results highlight that they can also undermine friendships and mental health due to jealousy.

社交媒体友谊嫉妒

开发了一种评估社交媒体背景下友谊嫉妒的新方法。这一单因素、七项测量在心理测量上是合理的，显示了北美成年人的三个样本（研究 1，n = 491；研究 2，n = 494；研究 3，n = 415）和一个研究的有效性和可靠性的证据。 -、两年和三年稳定性（研究 3）。女性报告的社交媒体友谊嫉妒程度高于男性（研究 2 和 3），而年轻女性的社交媒体友谊嫉妒程度最高（与年轻男性和年长男性和女性相比；研究 2）。社交媒体友谊嫉妒与较低的友谊质量（研究 1）以及较高的社交媒体使用和特质嫉妒（研究 2）相关。社交媒体友谊嫉妒与内化症状之间的关系表明时间关联和纵向双向关系呈正向（研究 3）。具体来说，社交媒体友谊嫉妒预示着内化问题的增加，而内化问题则预示着更大的社交媒体友谊嫉妒，考虑到社交媒体友谊嫉妒和内化问题的性别和特征水平。焦虑和抑郁的成年人可能倾向于通过社交媒体监控对其友谊的威胁，并因此而经历负面后果。尽管社交媒体互动可能与积极的幸福感和社会联系有关，但我们的研究结果强调，它们也会因嫉妒而破坏友谊和心理健康。
