Healthy Military Families Undergird National Readiness

Military families navigate a health system while experiencing mobility, operational demands, and long-term service commitments[DM2.1]. Frequent relocations disrupt continuity of care[KS3.1], often forcing families to change providers and rebuild local support networks. These shifts can delay treatment and weaken preventive care.

Deployment cycles add further strain. Families adjust roles, income patterns, and[LQ4.1] caregiving responsibilities, often under stress. Reintegration periods bring their own challenges as families reestablish routines and relationships. Over time, these transitions can affect mental health, child development, and family stability.

Across Department of War (DoW) systems, health care for military families spans federal programs, private providers, and community services. Coordination gaps can limit access to timely, consistent care. Data fragmentation makes it harder for agencies to track outcomes or tailor services to family needs. These constraints mirror broader health system challenges, where limited information flow and workforce gaps reduce responsiveness.

The result is not a single barrier, but a pattern of disruptions that compound over time. For military families, these gaps can affect health, readiness, and long-term well-being.

THE APPROACH

Building evidence that reflects real family needs.

Abt partnered with the Naval Health Research Center (NHRC), with support from the Defense Health Agency, to build one of the most comprehensive evidence bases on military family health. The work centers on the Millennium Cohort Family Study, the only DoW-wide, longitudinal study focused on military families.

Since 2009, Abt’s end-to-end research contributions have included literature reviews, survey design and weighting, data quality assessment, non-response analyses, hypothesis testing, and manuscript development. We collaborate closely with NHRC scientists to address DoW and stakeholder priorities, applying rigorous statistical methods to large-scale survey data from the Family Study. 

Key areas of focus include:

• Behavioral health and well-being. How stress, trauma, and transitions affect families, and how they seek care.
• Family dynamics and child development. How military life influences relationships and long-term outcomes for children.
• Deployment and reintegration. How families adjust during and after service-related separations.
• Transition to civilian life. How families navigate new systems after military service.

The Millennium Cohort Family Study provides DoW a sustained, longitudinal view of family health as a core component of force readiness and retention. Key findings have included: 

• Behavioral health needs affected a large share of military spouses. A 2025 Millennium Cohort Family Study analysis of 17,485 newly enrolled military spouses found that more than 40% screened positive for at least one behavioral health condition, including depression, anxiety, or PTSD. The findings underscored the cumulative stress tied to military life transitions, caregiving demands, and deployment-related pressures.
• Many military spouses struggled to meet core health benchmarks. A 2019 study found that only 44% of military spouses met healthy weight benchmarks, while 61% met recommended sleep targets. The study also showed that spouses experiencing weaker social support had significantly lower odds of meeting healthy sleep, alcohol-use, and smoking goals, highlighting the relationship between family stress and long-term health outcomes.
• Opioid risk patterns often affected both service members and spouses. A 2021 dyadic study found that 7% of both service members and spouses met at least one of the criteria for high-risk opioid use. The analysis also showed that spouses were more than five times as likely to receive long-term opioid therapy when the service member did, demonstrating how health risks can spread across households and reinforcing the need for family-centered approaches to care.

Research from the Millennium Cohort Family Study showed clear links between deployment stress, spouse mental health, child well-being, and military readiness. Those findings shaped guidance and outreach through Military OneSource— a DoW support program for service members, military spouses, and their families—as well as the Defense Health Agency, and the Psychological Health Center of Excellence. For example, studies on child mental health and family communication informed official resources that connect families to counseling, Military Kids Connect, and family readiness services.

The research also influenced how the DoW approached spouse resilience and behavioral health support. A 2018 study on psychiatric conditions among military spouses was later cited in a Defense Health Board report on mental health access for military beneficiaries. That report recommended stronger family resilience programs, improved spouse feedback systems, and more tailored support across the services. Other studies on military life stress and perceived support among spouses informed peer-support guidance and outreach tied to Family Readiness Groups, Key Spouse programs, and Military OneSource support networks.

While no single study drives policy alone, this body of work helps leaders align resources with real needs and refine programs over time as those needs evolve.

Military readiness depends on more than training and equipment. It depends on whether service members can focus on their mission, knowing their families have stable, reliable support.

There are also clear workforce implications. Retention and recruitment depend in part on how families experience military life. When families feel supported, service members are more likely to continue their service. When gaps persist, the effects show up in turnover and increased demand for support services.

Beyond individual programs, the Millennium Cohort Family Study strengthened the military’s long-term policy infrastructure for family health research. Methodology and recruitment studies helped validate this study as a trusted, long-running evidence platform used by DoW leaders and policymakers. Federal notices and Navy program documents describe the study as a tool to guide interventions and inform future policy decisions. This sustained research framework continues to support planning around spouse readiness, transition stress, substance misuse, and family-centered prevention programs across the military health system.

In practical terms, this body of work helps federal clients make better decisions. For military families, that means clearer pathways to care, fewer disruptions, and a more stable foundation over time.
