Replication and extension of the military family stress model: The after deployment adaptive parenting tools ADAPT4U study.

The military family stress (MFS) model conceptualizes that wartime deployments and post-traumatic stress disorder (PTSD) symptoms are associated with couple, parenting, and child adjustment difficulties. The aim of this study was to replicate and extend the military family stress model by examining the associations among deployment length, PTSD symptoms, marital functioning, parenting practices, and child adjustment in a replication sample of both National Guard and Reserve (NG/R) as well as active-duty service member families. The MFS model is extended to test whether these relationships vary between mothers and fathers. The sample included 208 families enrolled in a randomized controlled trial of a parenting program for military families (94.4% of fathers and 21.6% of mothers were deployed). Replicating the MFS model, we specified parenting, marital quality, and child adjustment as latent variables and conducted multi-group structural equation models. Parenting practices were positively associated with marital quality and child adjustment. PTSD symptoms were negatively associated with marital quality. The indirect effect from PTSD symptoms to parenting practices through marital quality was marginally significant. The indirect effect from marital quality to child adjustment through parenting practices was significant. There were no significant gender differences between the two structural models. This study provides empirical support for the MFS model. Results demonstrate that deployment-related stressors are significantly associated with parent and family functioning. Parenting programs for military families might effectively target similar risk processes among both mothers and fathers.

Resilience and Posttraumatic Stress Disorder Symptoms in National Guard Soldiers Deployed to Iraq: A Prospective Study of Latent Class Trajectories and Their Predictors.

This study examined the prospective course of posttraumatic stress disorder (PTSD) symptoms in a cohort of National Guard soldiers (N = 522) deployed to combat operations in Iraq. Participants were assessed 4 times: 1 month before deployment, 2-3 months after returning from deployment, 1 year later, and 2 years postdeployment. Growth mixture modeling revealed 3 distinct trajectories: low-stable symptoms, resilient, 76.4%; new-onset symptoms, 14.2%; and chronic distress, 9.4%. Relative to the resilient class, membership in both the new-onset symptoms and chronic distress trajectory classes was predicted by negative emotionality/neuroticism, odds ratios (ORs) = 1.09, 95% CI [1.02, 1.17], and OR = 1.22, 95% CI [1.09,1.35], respectively; and combat exposure, OR = 1.07, 95% CI [1.02, 1.12], and OR = 1.12, 95% CI [1.02, 1.24], respectively. Membership in the new-onset trajectory class was predicted by predeployment military preparedness, OR = 0.95, 95% CI [0.91, 0.98], perceived threat during deployment, OR = 1.07, 95% CI [1.03, 1.10], and stressful life events following deployment, OR = 1.44, 95% CI [1.05, 1.96]. Prior deployment to Iraq or Afghanistan, OR = 3.85, 95% CI [1.72, 8.69], predeployment depression, OR = 1.27, 95% CI [1.20, 1.36], and predeployment concerns about a deployment's impact on civilian/family life, OR = 1.09, 95% CI [1.02, 1.16], distinguished the chronic distress group relative to the resilient group. Identifying predeployment vulnerability and postdeployment contextual factors provides insight for future efforts to bolster resilience, prevent, and treat posttraumatic symptoms.
