^*Decrease in scores indicates a reduction in perceived barriers.

Individual items were scored on a 5-point Likert scale with 1=Strongly disagree, 2=Disagree, 3=Neutral, 4=Agree, and 5=Strongly agree. Subscale scores were calculated as the average of scores on the individual items that load on that factor.

^†Increase in scores indicates an increase in self-efficacy

Individual items were scored on a 5-point Likert Scale with 1=Not at all confident, 2= A little confident, 3=Moderately confident, 4=Very confident, and 5=Extremely confident. Subscale scores were calculated as the average of scores on the individual items that load on that factor.

^§Total number of participants (intensive intervention and minimal intervention group combined) <93 based on the number of participants who answered specific questions on baseline and twelvemonth surveys
