To ensure the dosage of intervention delivered in terms of the amount, frequency, duration, and breadth would be adequate to assess the quality and to manage outcomes, such as physical activity levels, self-efficacy, stages of change and quality of life, the following measures has been taken. An advisory committee has been set up with the purpose to develop an appropriate programme for Hong Kong Chinese childhood cancer survivors. The committee includes an associate professor, a lecturer and a research student at a local university with considerable experience of conducting psychological interventions among children, a paediatric oncologist and a oncology nurse specialist with rich experience in taking care of children with cancer and one assistant professor of Sports and Recreation Management with extensive experience and professional knowledge in conducting adventure-based training for children. In addition, the content of the programme that related to adventure-based training activities has been sent to a professional adventure-based training centre for content validation. The programme has been implemented on four different days within six months in a day camp training centre, such as at 2-week, 2-month, 4-month and 6-month after the day of recruitment. The programme has been implemented in small group with maximum 12 participants in one group. Health education talks and workshop have been implemented in between adventure-based training activities in day camp centre, conducted by healthcare professionals working in a local university. Adventure-based training activities have been led by two qualified adventure-based training instructors with extensive experience and professional knowledge in conducting such training for children. Additionally, at least two healthcare professionals join the adventure-based training to monitor the physical condition of the survivors and their fitness to join the adventure-based training activities.
