In Wambach and Koehn (2004) an error was published under the heading ‘Ethical considerations’ on page 363. The text was incorrect and should have read:

Ethical considerations

Human subjects committees from both of the participating institutions reviewed and approved the study prior to implementation. The participants were fully informed about the study procedures, benefits, and risks. Teen participants signed informed consent forms at the time of enrollment in the study.

We apologize for this error.
