NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.

Measuring Acceptability and Engagement of the Keep It Up! Internet-based HIV Prevention Randomized Controlled Trial for Young Men who have Sex with Men
Background:
Since 2010, HIV diagnoses among men who have sex with men (MSM) have remained stably high while decreasing for heterosexual men and women. The burden of infection has disproportionately impacted younger MSM of color relative to other populations. Despite the increased risk, there are few HIV prevention programs targeted to diverse and young MSM. The Keep It Up! (KIU!) online intervention was created to address the HIV prevention needs of this population.
Objective:
The objective of this study was to examine the acceptability and engagement of KIU!, and explore any differences by demographics, within the context of a randomized controlled trial (RCT).
Methods:
Between May 2013 and December 2015, 445 participants were randomized into the intervention arm of the KIU! RCT. Data were taken from the baseline assessment, KIU! 2.0 intervention modules, and immediate post-test assessments of intervention acceptability and engagement. Outcomes of interests were qualitative and quantitative measures of intervention acceptability and engagement as well as process measures (i.e., star ratings of intervention content and paradata on time spent in intervention).
Results:
Participants were an average of 24 years old, 62.9% (280/445) identified as a racial or ethnic minority, 86.5% (385/445) identified as gay, and 84.3% (375/445) reported having at least some college education. Most participants rated the intervention content highly (4 out of 5 stars) and gave the intervention an average acceptability score of 3.5 out of 4. Compared to White participants, Black participants found the intervention more useful (p = .03), engaging (p < .001), and acceptable (p = .001); Latino participants found the intervention more engaging (p = .03); and “other” non-White participants found the intervention more engaging (p = .008) and acceptable (p = .02). Participants with high school or less education found the intervention more useful, engaging, and acceptable, and were more likely to give intervention content a five star rating than college educated participants (p-values = .047, <.001, .002, .01 respectively) or those with graduate degrees (p-values = .04, .001, < .001, .004 respectively). White participants showed the most variation between education levels and reporting positive attitudes towards the intervention. Among Black participants, graduate degree-earning participants spent significantly more time on the intervention than high-school or less educated participants (p = .02).
Conclusions:
Overall, participants gave the intervention high acceptability and engagement ratings; but it was most acceptable and engaging to participants who were younger, identified as racial and ethnic minorities, had less education, and lived in the South. As these are all groups with greater burden of HIV infection, the KIU! intervention is promising as a primary HIV prevention tool. Future implementations of KIU! are needed to assess its acceptability outside of the highly controlled environment of an RCT.
