Official title
Effectiveness, Intention, and Behavior in Creighton Model NFP Use
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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).
