2. 1. Promoting adolescents' physical activity @ school

   Author : Anna-Karin Lindqvist; Ann Öhman; Luleå tekniska universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiotherapy; Fysioterapi;

   Abstract : The overall aim of this thesis was to explore the development of a health-promoting intervention that uses empowerment and information and communication technology, to examine the impact of the intervention and to describe adolescents' and parents' experiences of the intervention. This thesis includes four studies, three of which used a qualitative approach (I, III and IV) and one of which used a mixed method approach (II). READ MORE
