A conceptual explanation of risk-reduction behavior and intervention development.

Area of Science:

• Health Behavior Science
• Medical Sociology
• Reproductive Health

Background:

• Advanced maternal age is a known risk factor for fetal abnormalities.
• Prenatal diagnosis, such as amniocentesis, can identify these risks.
• Understanding factors influencing test acceptance is crucial for public health.

Purpose of the Study:

• To examine the acceptance or rejection of amniocentesis in women at risk due to maternal age.
• To utilize a new conceptual model of health behavior to explain this risk-reduction response.
• To identify individual characteristics and external factors influencing prenatal diagnostic test decisions.

Main Methods:

• A multivariate analysis approach was employed.
• 203 women at risk for fetal abnormalities due to maternal age were studied.
• The study assessed individual characteristics and significant external factors impacting test acceptance.

Main Results:

• A multivariate approach provided a more comprehensive explanation for the nonuse of prenatal diagnosis.
• Client-specific factors, alongside environmental influences, were significant.
• Environmental factors included financial support, information sources, social support, and client-provider interactions.

Conclusions:

• The study highlights the importance of both individual and environmental factors in prenatal diagnostic test decisions.
• A conceptual model effectively explains the complex factors influencing the acceptance or rejection of amniocentesis.
• The findings demonstrate the utility of conceptual models for developing targeted health interventions.
