This study explores differences in the use of CyclePro (CPG), a fertility-tracking app developed by Couple to Couple League (CCL), between those exposed to it as a part of natural family planning (NFP) instruction versus those who find it on their own. An anonymous data set of 17,543 CPG accounts opened between April 2013 and June 2016 was used for analysis. Nonmember users opened the most accounts (58 percent, = 10,134), CCL members represented 38 percent ( = 6,758) of new accounts, and 207 CCL teachers (4 percent) were using CPG for personal charting. Significantly more nonmember accounts had zero days of use after the initial opening compared to CCL member accounts (61 percent vs. 23 percent, respectively, χ = 2,405.9, < .001). Conversely, significantly more CCL member accounts were used for ninety days or longer than nonmember accounts (47 percent vs. 13 percent, respectively, χ = 2,404.2, < .001). CCL students-those who began using the app as part of a formal NFP teaching curriculum-were more likely to use the app for > six cycles compared to nonmembers. In accounts with at least one complete cycle, CCL students were the most diligent at daily recording (95 percent of cycle days with observation recorded) followed by CCL members (88 percent) and nonmembers (76 percent). CCL teachers had the lowest frequency of cycle days with a recorded observation (73 percent). Within each cohort, accounts with > six recorded cycles had a lower proportion of cycle days with an observation recorded, likely reflecting increasing knowledge of their personal fertility patterns. Long-term users who had no known formal training in NFP still had the lowest proportion cycle days with a fertility observation. We conclude formal NFP instruction increases the probability of long-term app use, and regardless of training, long-term users will likely record observations on about 70 percent of cycle days.
"CyclePro™ users with NFP training were more persistent and diligent about daily data input than those without training."
本研究探讨了作为自然计划生育（NFP）指导一部分接触到生育追踪应用程序CyclePro（CPG）的人群与自行发现该应用程序的人群在使用上的差异。分析使用了2013年4月至2016年6月期间开设的17543个CPG账户的匿名数据集。非会员用户开设的账户最多（58%，即10134个），CCL会员占新账户的38%（即6758个），207名CCL教师（4%）将CPG用于个人记录。与CCL会员账户相比，初始开户后使用天数为零的非会员账户明显更多（分别为61%和23%，χ = 2405.9，P <.001）。相反，使用90天或更长时间的CCL会员账户明显多于非会员账户（分别为47%和13%，χ = 2404.2，P <.001）。CCL学生——那些作为正式NFP教学课程的一部分开始使用该应用程序的人——与非会员相比，更有可能使用该应用程序超过六个周期。在至少有一个完整周期的账户中，CCL学生在每日记录方面最勤奋（记录观察的周期天数占95%），其次是CCL会员（88%）和非会员（76%）。CCL教师记录观察的周期天数频率最低（73%）。在每个队列中，记录周期超过六个的账户中记录观察的周期天数比例较低，这可能反映出他们对个人生育模式的了解增加。没有已知NFP正式培训的长期用户记录生育观察的周期天数比例仍然最低。我们得出结论，正式的NFP指导增加了长期使用该应用程序的可能性，并且无论是否接受培训，长期用户可能会在大约70%的周期天数记录观察结果。
“接受NFP培训的CyclePro™用户在每日数据输入方面比未接受培训的用户更持久、更勤奋。”
