The development and application of a protocol for the writing, assessing, and validating of a corpus of relationship-focused text messages for new and expecting fathers.

In developed countries, antenatal education aims to reduce difficulties that mothers and fathers experience during transition to parenthood. However, fathers are often distracted from preparing themselves by the attention given to preparing and supporting mothers. Developments in digital communication present alternative means of supporting fathers at this time. Studies, across a range of health concerns, have reported successful outcomes from text-based interventions. Text messaging, focusing on the issues that cause paternal distress at this time, could provide timely, targeted, and effective support to fathers in their transition to parenthood. This study aimed to develop a corpus of messages that could be sent to new fathers during pregnancy and in the months after birth. Messages were intended to support new dads in caring for their own physical and mental health, nurturing strong relationships with their child, and developing strong parenting partnerships. The process employed in message development was similar to that previously employed in developing messages for people who had experienced a cardiac event. A corpus of messages and linked information focusing on fathers' relationships with their children, partners, and themselves were initially developed by a core group. The corpus was then culled, refined, and expanded by a larger, more diverse, group of experts ( n = 46), including parents, academics, and practitioners. The iterative, consultative process used in this study proved to be a functional way of developing and refining a large corpus of timed messages, and linked information, which could be sent to new fathers during their transition to fatherhood.
