Trial Outcomes & Findings for Transitioning Youth Out of Homelessness 2.0 (TYOH 2.0) (NCT NCT05781503)

Missing data (due to participants opting out of questions) resulted in some variation in the population number for each subscale.

To examine intervention feasibility and acceptability, quantitative measures consisting of recruitment/enrolment/dropout metrics will be utilized. Recruitment rate will be estimated as the proportion of contacted individuals who express interest in participating in the study. The enrollment rate will be calculated as the proportion of recruited individuals who are eligible and consent to participate in the study. Dropout rates will be separately calculated for intervention and control groups at the end of the study as the 1 - proportion of randomized participants who completed the study at 12 months. Exact (Clopper-Pearson) 95% confidence limits will also be calculated.

We conducted focus groups with intervention (rent subsidy + identity capital intervention) participants. Focus group questions explored intervention feasibility and acceptability. Focus group data from all time points was analyzed together.

Feasibility and acceptability of the coaching component of the identity capital intervention was assessed by coaching session attendance, as recorded by coaches. Overall coaching session attendance was measured as the percentage of total possible coaching sessions attended over the 12-month period (maximum 24 sessions).

Feasibility and acceptability of the co-designed leadership guide component of the identity capital intervention was assessed using the Intervention Engagement Questionnaire (self-report measure was developed for this study and administered only to intervention participants).

The 20-item self-report Housing Security Scale contains the following sub-scales: Subjective Stability (range 5-30; higher scores indicate more housing security); Safety Net (range 3-18; higher scores indicate more housing security); Threats to Stability (range 7-42; higher scores indicate less housing security).

The Multi-Measure Agentic Personality Scale (MAPS20) is a 20-item validated self-report measure that explores domains related to identity capital. The MAPS20 contains the following sub-scales: Self-Esteem; Purpose in Life; Internal Locus of Control; Self-Efficacy/Ego Strength. Each subscale has a score range of 5-30, with higher scores indicating greater identity capital.

This five-item self-report measure was developed for this study and explores engagement in education (secondary or post-secondary), employment (full- or part-time; formal and informal), and training (paid or unpaid apprenticeship). Employment, education, and training (EET) is a composite binary outcome, where EET = 1 if participants are attending classes, employed, or participating in a training program, and EET = 0 otherwise.

The 20-item self-report Housing Security Scale contains a composite binary indicator of housing need, in addition to the previously reported continuous outcome sub-scales. The number of participants responding in the affirmative is reported (affirmative response indicates that the participant has unmet housing needs).

This 17-item self-report measure was developed for this study and explores domains related to: age; gender; race/ethnicity; sexual orientation; immigration status; child welfare involvement; homelessness entrenchment; education; social support; financial support; physical health support; mental health support; food security.
