Adolescents as a population are rarely involved in user needs research (Kroemer 2006).As a specific user group they often have tomake use of products and services that are designed for adult or child populations. For some products this does not always pose a problem, however, in the case of medical devices, where lack of user satisfaction can lead to poor adherence of use, (Suris et al. 2004) there is potential for a negative impact on an the user’s health (Fielding & Duff 1999).
