Understanding what peer-reviewed research actually shows about divorce helps separate evidence-based approaches from popular but unproven ones.
Research Design Hierarchy for Divorce
When evaluating divorce research, the hierarchy of evidence matters:
- Systematic reviews and meta-analyses: Synthesize all available research on divorce
- Randomized Controlled Trials (RCTs): The gold standard for treatment research
- Cohort studies: Long-term follow-up of divorce development
- Case studies: Individual experiences — valuable for generating hypotheses
Key Research Findings on Divorce
The strongest evidence supports:
- Cognitive Behavioral Therapy (CBT) for most divorce presentations
- Regular aerobic exercise has effects comparable to medication for divorce
- Social connection as a primary protective factor
- Sleep as bidirectionally related to divorce
Interpreting Divorce Research Headlines
Many divorce research headlines overstate findings. Look for: replication, sample size, peer review, and whether the study was conducted in relevant populations.
