Summary

The Creighton Model (CrM) FertilityCare System is a natural family planning method that teaches couples to recognize and chart the signs of fertility and infertility in the woman's cycle and to use that knowledge to either achieve or avoid a pregnancy. The method is natural, safe and effective, and it helps the couple understand their fertility. Trained practitioners at FertilityCare Centers teach the Creighton Model across the country, internationally and long distance. Several FertilityCare Centers and the University of Utah are conducting a study to evaluate the effectiveness of the Creighton Model (CrM) for new and return users wanting to avoid pregnancy. While past studies have shown that the Creighton Model is a highly effective method, this study will use new ways to measure how well it works. This is important because the knowledge gained will improve comparisons between the Creighton Model and other family planning methods. The study will also explore intentions and behaviors of couples to avoid or achieve a pregnancy. The investigators hypothesize that for the CrM the pregnancy rate during perfect use to avoid pregnancy will be about 1% and the behaviorally determined avoiding-related pregnancy rate for the CrM will be about 6%. The investigators will also evaluate the pregnancy rate during "typical use" without a previously stated intention to conceive (in CrM terms, a mixture of avoiding and achieving-related behavior).

Clinical Details

Official title: Effectiveness, Intention, and Behavior in Creighton Model NFP Use

Study design: Observational Model: Cohort, Time Perspective: Prospective

Primary outcome: Pregnancy rates during perfect and typical use of the Creighton Model FertilityCare System (CrM) to avoid pregnancy in a way directly comparable to the approach used in recent family planning effectiveness studies

Secondary outcome: The intention status of all pregnancies according to standard measures of intended, mistimed and unwanted pregnancy while recognizing the significant limitations of these measures

Detailed description: There are a variety of natural family planning (NFP) methods available today that differ in algorithm and biomarkers used to identify women's fertile window. This study will directly evaluate the NFP system known as the Creighton Model FertilityCare System (CrM). The Creighton Model System is a well-established educational system about fertility which involves no devices. The CrM teaches women a standardized way of observing and describing their vaginal discharge each day during routine use of the bathroom, and interpreting the changes in vaginal discharge to determine whether they are likely to be fertile that day or not. Vaginal discharge changes as tracked by the CrM are an accurate indicator of the changes in secretions from the uterine cervix that relate to the approach of ovulation. This study will also examine the relationship between a couple's stated intentions to achieve or avoid a pregnancy during each menstrual cycle with their sexual behavior during the same cycle. There is growing consensus among researchers that current measures of pregnancy intention are simplistic at best, and at worst can be very misleading. One of the purposes of the study is to explore the multiple dimensions of pregnancy motivations, intentions, and behaviors by newer detailed measures. This study will enroll couples who are new or returning CrM users and who are trying to avoid a pregnancy at the time they begin use of the CrM. The participants will be recruited from CrM FertilityCare Centers. The design is a prospective cohort study, which is the optimal study design to assess different measures of effectiveness and intendedness simultaneously in a group of NFP users. Several of the key measures of intention and behavior required for this study must be assessed prior to the outcome of actual use of CrM over time and the outcome of pregnancy, to avoid recall bias. Outcomes for this study require relatively precise assessment of the timing of both intentions and behaviors, which is simply unavailable from recall. We plan to enroll at least 300 and up to 400 couples in the study. This represents 60% (300/497) of the estimated available and eligible couples learning the CrM for use to avoid pregnancy in one year at the participating FertilityCare Centers.
