* Values for 125 participants missing from univariate treated as a separate category
** In the past six months
† All Chi-Square tests were performed with one degree of freedom (df = 1), with the exception of the
'symptoms of depression' variable, where df = 2.
‡ Chi-Squared Test were applied to all categorical variables. A Wald Test was applied to the continuous
'age' variable, yielding a Wald Chi-Square value.
