For this pilot study, we collected feasibility information, which may not be necessary in further studies.
Technical or hardware problems encountered while using the app will also be collected during feasibility evaluation and regular monitoring and evaluation using both qualitative interviews and checklist form.
Compliance, the reason for non-compliance, satisfaction, technical or hardware problem encountered while using the app and suggestions on improvement will be collected during feasibility evaluation and regular monitoring and evaluation field visits.
The acceptability of a CCBT programme to adolescents; and the willingness of clinicians to recruit participants and of participants to be randomised, recruitment rates, attrition rates and questionnaire completion rates will be collected for feasibility analysis.
When designing our study it was decided – due to feasibility – to collect only one acute phase serum sample.
Our main aim was to collect information about the feasibility of testing a HHF and to a lesser extent to evaluate the effectiveness of the intervention.
A more robust RCT or cluster RCT design was not possible within the study budget and timeframe and thus the aim of the study was to collect data primarily on feasibility to inform a full scale RCT in the future.
The aim of this study was to measure the feasibility of collecting self-collected DBS and saliva samples in a population-based study, where participants would be asked to ship the samples by standard postal service.
Similarly, although an important feature of a definitive study may be a cost-effectiveness data collection and analysis, a limitation is that such data will not be collected during this feasibility work.
These will improve the data quality compared to that collected during preliminary feasibility experiments.
