A pilot study (n = 41) was conducted to test the effects of three educational treatments (DVD versus Pamphlet versus DVD plus 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; approximately 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.
