1The test results comparing scores on mental disorder screening measures for demographic variables are reported as t(degrees of freedom)=test statistic for g = 2 groups and as F(numerator degrees of freedom, denominator degrees of freedom)=test statistic for g> 2 groups.
2Total percentages may not sum to 100 and ns may not sum to 772 due to non-response or “other” responses.
4A limited number of participants reported values for PD (PDSS-SR) because selecting “No” for “ever having experience with panic attacks” or “having panic attack in the last 7 days”, meant participants were not presented the rest of the PDSS-SR questions.
*p<.05, **p<.01, ***p<.001 – Statistically significantly different.^Sample size between 1 and 5, so data not presented. “-“ No data available.
Lettered superscripts within each column category indicate statistically significant differences between category groups with different letters on outcome at p ≤ .05.
