Objective: This review sought to summarize existing knowledge to inform the development of an online intervention that aims to improve quality of life after cancer treatment.Methods: To inform our intervention, we searched for studies relating to Web-based interventions designed to improve quality of life in adults who have completed primary treatment for breast, prostate, and colorectal cancer (as these are 3 of the most common cancers and impact a large number of cancer survivors). We included a variety of study designs (qualitative research, feasibility/pilot trials, randomized trials, and process evaluations) and extracted all available information regarding intervention characteristics, experiences, and outcomes. Data were synthesized as textual (qualitative) data and analyzed by using thematic analysis.Results: Fifty-seven full text articles were assessed for eligibility, and 16 papers describing 9 interventions were analyzed. Our findings suggest that cancer survivors value interventions that offer content specific to their changing needs and are delivered at the right stage of the cancer trajectory. Social networking features do not always provide added benefit, and behavior change techniques need to be implemented carefully to avoid potential negative consequences for some users. 14,15
ConclusionsReviews of heterogeneous, complex interventions frequently conclude that the evidence is "weak" or "mixed" 12,16 and often fail to address intervention usability and acceptability. 13 It is important to understand how an intervention works in and suits a given con-
| METHODSTo inform decision making for intervention development purposes in a timely fashion, we followed rapid review methods [22][23][24][25] to identify studies of interest. We used thematic synthesis for analyzing the data, also drawing on approaches used in ICA. 19 We adhered to the AMSTAR: A Measurement Tool to Assess Reviews criteria 26 (see Appendix A for further details).
