As there is a lack of evidence attesting the equivalent item functioning across genders for the most employed instruments used to measure pathological gambling in adolescence, the present study was aimed to test the gender invariance of the (GBS-A), a new measurement tool to assess the severity of Gambling Disorder (GD) in adolescents. The equivalence of the items across genders was assessed by analyzing Differential Item Functioning within an Item Response Theory framework. The GBS-A was administered to 1,723 adolescents, and the graded response model was employed. The results attested the measurement equivalence of the GBS-A when administered to male and female adolescent gamblers. Overall, findings provided evidence that the GBS-A is an effective measurement tool of the severity of GD in male and female adolescents and that the scale was unbiased and able to relieve truly gender differences. As such, the GBS-A can be profitably used in educational interventions and clinical treatments with young people.
由于缺乏证据证明在用于测量青少年病理性赌博的最常用工具中，各项目在不同性别间具有等效功能，本研究旨在测试青少年赌博严重程度量表（GBS-A）的性别不变性，这是一种评估青少年赌博障碍（GD）严重程度的新测量工具。通过在项目反应理论框架内分析项目功能差异来评估各项目在不同性别间的等效性。对1723名青少年施测GBS-A，并采用等级反应模型。结果证明，GBS-A施用于男性和女性青少年赌博者时具有测量等效性。总体而言，研究结果表明，GBS-A是测量男性和女性青少年GD严重程度的有效工具，该量表无偏差，能够消除真正的性别差异。因此，GBS-A可有效地用于针对年轻人的教育干预和临床治疗。
