The invalidation of non-binary identites has signifigant mental health implications for these individuals. In a study from “Invalidation Experiences Among Non-Binary Adolescents” participants reported that “ongoing invalidation led them to repress their feelings or to question whether they were real or valid. This led to intense self-doubt, coupled with significant distress” (Johnson 228). This can also been seen from study results as a whole, which demonstrated that non-binary individuals have worse mental health outcomes than their binary-identified counterparts. 
This worsened mental health may be experienced in various ways, so additional research may be needed to clarify how socially enforced thought patterns and experiences may contribute. “Invalidation in this ethnically diverse, qualitative sample was tied to feelings of self-doubt, confusion, increased rumination, and internalized shame” and contributes to a negative relationship between internalized transphobia [or internalized gender invalidation] of non-binary individuals and life satisfaction i.e. if they have internalized this, they will not be as happy. (Flynn and Bhambhani 230).
When it comes to specific mental health complications such as “experiencing depressed mood, seriously considering suicide, and attempting suicide”, non-binary individuals also experience higher levels of complications than their cisgendered peers (Price-Feeney). In a study that focuses on mental health of non-binary and transgender youth and young adults, non-binary individuals were found to have “high rates of depression and suicidality, violence, and substance use” (Newcomb 645). This demonstrates that these individuals are experiencing higher rates of mental issues and outcomes viewed as negative and often it is due to the invalidation previously mentioned. This negative cycle that keeps non-binary people from understanding and expressing themselves in as positive a way as their cisgendered counterparts.
