The current study aimed to examine the test–retest reliability and sensitivity of the Trans Collaborations Clinical Check-In (TC³) in a 3-month period with four assessment points at baseline, 1, 2, and 3 months to examine its utility as a clinical progress monitoring measure. This study builds on the initial validation study conducted by Holt et al. (2019). The sample of 32 transgender and gender diverse (TGD) participants were chosen who met screening for at least modest depression and anxiety, and did not have other significant risk factors (e.g., mania, self-harm). Participants completed a battery of measures that assessed mood, well-being, and gender-related constructs at each of the time points in addition to demographic questionnaires. Overall, the TC³ exhibited excellent test–retest reliability. While there was no systematic change in scores, there was some random variation of scores around the mean; and large, within-person correlations between time points. The TC³ also demonstrated convergence with many of the gender-related constructs, and to a lesser degree demonstrated criterion validity with mental health constructs. Further longitudinal study with larger samples in addition to study within intervention frameworks are necessary next steps to understand the utility of the TC³ for assessing systematic change over time. Overall, the current study highlights the initial utility of the TC³ to measure aspects of gender-related well-being across time, such as during health or behavioral health services.
