It's complicated - Factors predicting decisional conflict in prenatal diagnostic testing
Cécile Muller1, Linda D Cameron2
1Public Health Genetics, Genetic Disorders, Murdoch Children's Research Institute, Parkville, Vic., Australia.
Summary
Decisional conflict regarding prenatal genetic testing is influenced by perceived benefits, test reliability concerns, understanding of the condition, and partner/doctor preferences. Addressing these factors can improve decision-making for expectant parents.
Area of Science:
- Reproductive genetics
- Medical decision-making
- Psychosocial factors in healthcare
Background:
- Prenatal genetic testing offers insights into fetal abnormalities but involves complex psychosocial and clinical considerations.
- Understanding these dimensions is crucial for informed decision-making regarding testing.
Purpose of the Study:
- To evaluate a model predicting decisional conflict in prenatal genetic testing decisions.
- To identify key psychosocial and clinical factors influencing these decisions.
Main Methods:
- 457 adults reviewed hypothetical scenarios involving prenatal genetic testing for various conditions.
- Participants completed validated measures assessing decisional conflict and related psychosocial/clinical variables.
Main Results:
- Perceived benefits of normal results, doubts about test reliability, and poor condition understanding predicted higher conflict.
- Fetal health worries, perceived partner disagreement, and desire to follow medical advice also increased decisional conflict.
Conclusions:
- Factors such as perceived benefits, test efficacy, condition comprehension, and interpersonal dynamics significantly impact prenatal testing decisions.
- These findings can guide communication strategies to support couples in making informed choices about genetic testing.

Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...
