Limitations of the study
Limitations of the study include relatively small sample size, short duration of follow‐up and possible bias due to incorrect self‐reporting of self‐tell outcomes. Nevertheless, to our knowledge, this research represents the first and largest study to develop and evaluate an APN model for use in prison settings. We are fully aware that fewer than half of the partners who index participants reported having personally told (7/17) could be confirmed. Yet, if all such reports of successful self‐tell notifications are indeed valid, the Impart choice model still proved three to four times more effective in successfully notifying at‐risk partners and generating HIV testing than self‐tell notification alone.
