Eighty-one homeless individuals completed three measures of anxiety and depression including: the Intolerance of Uncertainty Scale, Penn State Worry Questionnaire, and Patient Health Questionnaire-9. Psychometric properties of measures were examined; in addition, prevalence of generalized anxiety disorder and depressive symptoms and their relation to the amount of time spent homeless was explored. Similar to past research in clinical populations, analysis revealed strong internal reliability and validity in all measures. Intolerance of uncertainty and worry were shown to be endorsed more often at the start of homelessness whereas depression symptoms remained constant throughout homelessness. Specifically, anxiety symptoms were shown to decrease from clinical levels to nonclinical intensity but elevate as time spent homeless increases.
