The role of hyperventilation in producing symptoms in a non-clinical population as well as its relation to anxiety were investigated. A group of likely hyperventilators (n = 18) and unlikely hyperventilators (n = 16), balanced with regard to sex, were selected from a student population (N = 385) using a screening questionnaire of hyperventilation-related symptoms. Along with the screening questionnaire, all subjects were administered the State-Trait Anxiety Inventory (Speilberger, Gorsuch, and Lushene, 1970). The experimental groups were given an overbreathing test using room air and a control overbreathing test using carbon dioxide enriched air, which was expected to produce fewer symptoms. In addition, subjects' normal breathing rate and volume were measured and they were given two clinical questionnaires: the Symptom Checklist (Derogatis, 1977) and a subscale of face valid hyperventilation-related items from the MMPI. / Likely hyperventilators were found to report more symptoms than unlikely hyperventilators after overbreathing room air but not after overbreathing carbon dioxide enriched air. In addition, the symptoms reported by the likely hyperventilators after overbreathing moderately matched those originally reported on the screening questionnaire. Further, the likely hyperventilators' normal breathing showed higher volume and rate than the unlikely hyperventilators. Likely hyperventilators also scored higher on all the scales of the Symptom Checklist as well as the face-valid scale of hyperventilation-related items from the MMPI. Finally, a correlation of .42 was found between the original screening questionnaire of hyperventilation symptoms and the trait half of the State-Trait Anxiety Inventory. The results supported a relation between chronic hyperventilation and symptom experience in a non-clinical population, and between hyperventilation and anxiety. / Source: Dissertation Abstracts International, Volume: 43-07, Section: B, page: 2339. / Thesis (Ph.D.)--The Florida State University, 1982.
