A randomized controlled trial of positive-affect induction to promote physical activity after percutaneous coronary intervention.

Background: Within 1 year after percutaneous coronary intervention, more than 20% of patients experience new adverse events. Physical activity confers a 25% reduction in mortality; however, physical activity is widely underused. Thus, there is a need for more powerful behavioral interventions to promote physical activity.

Living with heart disease after angioplasty: A qualitative study of patients who have been successful or unsuccessful in multiple behavior change.

Objective: To document values, attitudes, and beliefs that influence behavior change among a diverse group of patients post-angioplasty.

Methods: Purposive and maximum-variation sampling were used to assemble a demographically diverse patient cohort (N=61) who had been successful or unsuccessful at post-angioplasty multibehavior change. Semistructured interviews and grounded theory methods were used to collect and analyze qualitative data.

An analysis of predictors of sustainability efforts at the Inner-City Asthma Intervention sites: after the funding is gone.

Background: The Inner-City Asthma Intervention was a national, multicenter implementation of an evidence-based intervention to reduce asthma morbidity in inner-city children that was funded by the Centers for Disease Control and Prevention. Funding was initially planned for 4 years beginning in April 2001, but because of budgetary changes funding ceased in September 2004, 6 months before the original plan. Some sites were able to sustain their asthma program when the funding ended and others were not.
