The text points out that researchers can gain a better understanding of how stepfamilies fare over time by using __________ studies.

• A. Survey
• B. Participant observation
• C. Field
• D. Longitudinal

Answer: (D)

Tracking the same families over multiple points in time is key to understanding how stepfamilies fare as time passes. This approach, a longitudinal study, lets researchers observe trajectories—whether adjustment, relationship quality, or child well-being improves, worsens, or stays stable—and see how early factors relate to later outcomes. A one-time survey only gives a snapshot, missing the sequence and timing of changes. Field or participant-observation methods offer deep context but don’t inherently follow the same families over time to reveal patterns. By following the same stepfamilies across years, longitudinal studies capture development and change, which is essential for understanding long-term outcomes in stepfamilies.
