We tested the feasibility of the introductory modules of an online couple-based program (STORK), designed to be grounded in empirically established risk and protective factors associated with couples' perinatal sexual well-being. STORK is a web-based program including psychoeducation and behavioral tasks to be completed by couples

After completing the initial STORK program's modules, couples self-reported on acceptability of the platform using 11 researcher-derived items modeled after prior similar work. Items assessed aspects such as enjoyment, overall organization, and amount of information for Module 0 and Module 1 using 7-point Likert-type response scales. Participants also provided open-ended suggestions for improvement.

Participants self-reported on 9 researcher-derived items assessing the content and layout of information presented in the STORK program such as platform layout, clarity and appropriateness of content using 7-point Likert-type response scales. Three open-ended questions asked about areas that were covered well, areas of improvement, and confusing terms/ideas.

Two researcher-derived items assessed ease of navigation and the relevance of graphics (i.e., images/videos) using 7-point Likert-type response scales; an open-ended question asked about specific suggestions to functionality of the platform.

Participants self-reported on their perceptions regarding inclusivity of the platform using 4 researcher-derived items completed on a 7-point Likert-type response scales. One open-ended question asked about specific suggestions to improve inclusivity of the program.

Participants self-reported how long it took them to complete the modules, and whether they considered this amount of time reasonable using a dichotomic (yes/no) item; if they responded negatively, then they were invited to provide reasons using an open-ended question.
