Looking Forward in Candidate Gene Research: Concerns and Suggestions.

Area of Science:

• Behavioral genetics
• Developmental psychology
• Family studies

Background:

• Candidate Gene × Environment (cGxE) interaction research is crucial for understanding individual differences in response to environmental factors.
• The field faces ongoing debate regarding its merits and future direction for advancing gene-environment interplay knowledge.
• Schlomer et al. (2015) published a target article, with Salvatore and Dick (2015) providing commentary.

Purpose of the Study:

• To address points of agreement and departure with commentary on cGxE research.
• To propose a framework for evaluating the quality of cGxE research.
• To guide future research in the field of gene-environment interactions.

Main Methods:

• The study is a scholarly reply to a commentary on a previous article.
• It involves a critical discussion of existing viewpoints on cGxE research.
• A list of 5 domains for evaluating cGxE research quality is presented.

Main Results:

• Identified areas of consensus and disagreement regarding cGxE research.
• Developed a 5-domain framework for assessing the rigor of cGxE studies.
• Provided a structured approach for researchers to enhance their work.

Conclusions:

• High-quality cGxE research is essential for advancing our understanding of gene-environment interplay.
• The proposed evaluation domains offer a practical guide for researchers.
• Adoption of these criteria will strengthen the field and its contributions to developmental science.
