The aim of this study is the development and analysis of the psychometric properties of a new instrument to assess the possible psychological abuse experienced in a group setting. The Psychological Abuse Experienced in Groups Scale was administered to 138 people who self-identified as former members of abusive groups. An exploratory factor analysis revealed a common factor, which showed appropriate reliability. The scale scores were correlated with a prior measure aimed to assess group abusiveness, providing evidence of external validity. Participants reported a higher degree of psychological distress than normative samples, and those who requested psychological counseling after leaving the group had suffered group psychological abuse to a greater extent. The scale covers a wide range of subtle and explicit abusive behaviors and overcomes the limitations of previous instruments, being useful in both research and applied settings.

小组量表中经历的心理虐待的发展和验证

这项研究的目的是开发和分析一种新工具的心理测量特性，以评估在小组环境中可能遭受的心理虐待。对138位自我认定为虐待群体前成员的人进行了“小组经历的心理虐待”量表。探索性因素分析显示了一个公共因素，该因素显示了适当的可靠性。量表分数与旨在评估组滥用行为的先前措施相关，从而提供外部有效性的证据。与标准样本相比，参与者报告的心理困扰程度更高，离开小组后要求心理咨询的参与者遭受团体心理伤害的程度更大。
