Background: While research pertaining to nonbinary microaggressions has become increasingly comprehensive in recent years, a measure specifically assessing this construct does not yet exist.Aims: The purpose of the present research was to develop and validate the Nonbinary Gender Microaggressions (NBGM) scale, which will allow future researchers to quantitatively examine nonbinary individuals’ experiences of microaggressions. Methods and Results: In Study 1 (n = 5), interviews with nonbinary individuals were conducted to explore their microaggressive experiences. The results of this study, as well as findings from previous qualitative research, were used to generate an initial pool of 92 items. In Study 2 (n = 158), a principal component analysis, which was used for item reduction, resulted in the retention of 41 items. In Studies 3 (n = 151) and 4 (n = 266), an exploratory factor analysis yielded a 23-item 5-factor solution (i.e., Negation of Identity [6 items], Inauthenticity [6 items], Deadnaming [4 items], Trans Exclusion [3 items], and Misuse of Gendered Terminology [4 items]), and a confirmatory factor analysis found that this solution demonstrates adequate model fit. Evidence of the measure’s scale score reliability, convergent validity, and incremental validity also were provided. Discussion: These findings indicate that, overall, the NBGM scale is a psychometrically sound measure of nonbinary individuals’ experiences of microaggressions. As such, this measure can be utilized by future researchers and clinicians to better understand nonbinary individuals’ microaggressive experiences.

Introduction: Access of transgender and gender diverse (TGD) youth to gender-affirming medical care (GAMC) has become a contentious topic in the West, with many members of the general population, politicians, and even some experts and academic researchers voicing concerns about possible adverse effects of GAMC on the mental and physical health of TGD youth. Due to these concerns, recent years have seen a significant rise in legislation restricting TGD youth from accessing GAMC in countries such as the United States, the United Kingdom, and Canada. However, in this critical review of the literature on the psychological (e.g., anxiety, depression, suicide, and body satisfaction) and physical (e.g., bone health, cognitive function, and fertility) health outcomes associated with GAMC among TGD youth, we argue that, given the state of current research, youth should not be restricted from accessing GAMC. Conclusions: Our findings reinforce the importance of close monitoring by doctors, counselling for TGD youth with respect to potential risks, and increased studies on the topic, especially those focusing on reproductive health.
