OBJECTIVE: To provide readers with information on various techniques to improve future health behavior EFA research. METHODS: Data from a health education questionnaire development study are analyzed to make the discussion of techniques concrete. RESULTS: There are numerous strategies to use when making a factor retention decision. CONCLUSIONS: The informed health-behavior researcher should use sophisticated factor retention techniques during EFAs. [ABSTRACT FROM AUTHOR]

A pilot study (n = 41) was conducted to test the effects of three educational treatments (DVD vs. Pamphlet vs. DVD + Pamphlet) on health-related quality of life (HRQoL), COPD information needs and self-efficacy among a referred sample of Certified Federal Rural Health Clinic patients (mean age = 61.51 years ± 6.29 years; ~61% female) suffering from COPD using a randomly-assigned, multiple-group pretest-posttest design with a control group. A MANCOVA testing planned multivariate contrasts determined patients receiving a DVD reported statistically significant higher levels of lung-specific physical functioning as compared to patients receiving a Pamphlet. Additionally, DVD patients reported clinically significant improvements on two dimensions of lung-specific HRQoL. No such improvements occurred within the Pamphlet and Control groups. The provision of self-management education as compared to usual care, however, did not improve the outcome variables examined. [ABSTRACT FROM AUTHOR]
