follow-up according to the schedule of the oncology units. besides, participants received an amount of time and attention that mimicked that received by the experimental group, but which is thought not to have any specific effect on the outcome measures. they were invited to attend leisure activities organized by a community centre in four different days during the study period. activities

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 were taken. an advisory committee was set up with the purpose to develop an appropriate integrated programme for hong kong chinese childhood cancer survivors. the committee included the researcher, an assistant professor 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, two professional adventure-based trainers 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 was sent to a professional adventure-based training centre for content validation. the programme was 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 was implemented in small group with maximum 12 participants in one group. health education talks and workshop were implemented in between adventure-based training activities in day camp centre, which were conducted by healthcare professionals working in a local university. adventure-based training activities were 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 joined the adventure-based training to monitor the physical condition of the survivors and their fitness to join the adventure-based training activities. data collection methods data collection methods approval for the study was obtained from the hospital ethics committees. to identify potential subjects, a leaflet containing details of the study and a demographic sheet have been mailed to all parents of childhood cancer survivors in the sunshine parents club. if children and their parents are interested in the research, they can return the demographic sheet by using the enclosed return-envelop to convey their willingness to participate in the study. a briefing session will then be conducted in the out-patient clinic to those

the involvement of their child. the children has also been invited to put their names on a special children's assent form and told that their participation is voluntary. after obtaining demographic data of participants, they have been asked to respond to the chinese version of the fs-c/fs-a, pa-se, cuhk-parcy, pascq and pedsql. they have also been assessed for muscle strength using a hand-held dynamometer. participants have been randomly assigned to the experimental and control groups. all participants received a telephone call inviting them to join the interventions according to their group assignment at an appointed time. data collection has been conducted again at 3, 6, 9 and 12 months after starting the intervention. all participants has been informed that there would be home visits for data collection. analysis the statistical package for social sciences (spss) software, version 19.0 for windows will be used to analyze quantitative data. intention-to-treat analysis will be used and missing data will be substituted by the last-observation-carried-forward procedure. the comparability of the experimental and control groups will be assessed by using inferential statistics (independent t-test and chi-squared test). descriptive statistics will be used to calculate the mean scores and standard deviation of different scales. mixed between-within subjects anova (split-plot anova) will be used to determine whether the adventure-based training programme was effective in reducing fatigue, increasing childhood cancer survivors' levels of physical activity, self-efficacy and muscle strength and enhancing their quality of life. in addition, friedman test will be used to determine any changes in stages of change between the experimental and control groups.
