Incorporating feasibility protocols in intervention research.

In this paper, we review some dimensions of feasibility research. Feasibility research focuses on the intervention process and addresses questions about whether and how an intervention can be evaluated and implemented. Feasibility studies are implemented prior to conducting an outcome-focused pilot study or full-scale evaluation to test the effectiveness of an intervention. We propose a feasibility framework that includes 10 possible dimensions to evaluate in a feasibility trial, including (a) recruitment capability, (b) data collection procedures, (c) design procedures, (d) social validity, (e) practicality, (f) integration into existing systems, (g) adaptability, (h) implementation, (i) effectiveness, and (j) generalizability. Among these dimensions we offer some priorities that researchers can consider in establishing feasibility. Although feasibility investigations can advance evidence-based practice in psychology and education, we review current challenges for researchers to consider when incorporating a feasibility protocol into their intervention research agenda.
