In the original publication of this article, the paragraph under the sub-heading ‘Methodological approach’ has been published incorrectly. The correct paragraph is provided in this erratum.

If the focus of a topic is outward, i.e. on the contents of opinion and on actual world experiences and happenings rather than on participants’ ‘inner feelings’, Percy [7] recommends that one should consider a generic qualitative approach. This approach may also be selected when: (1) the research problem and question require a mixed-methods methodology; (2) traditional qualitative approaches are inappropriate because the focus of the research, the content of the information desired, or the kind of data to be obtained does not fit these approaches; or (3) the researcher has a body of pre-knowledge about a topic that he or she wants to be able to describe more fully from the participants’ perspective [7].
