Evaluation of a Modified Version of the Posttraumatic Growth Inventory-Short Form BMC Research Methodology 2017 Apr;17(1):69

Kaur N, Porter B, LeardMann CA, Tobin TE, Lemus H, Luxton DD

This study sought to validate a modified measure of posttraumatic growth, personal growth, and change that may occur following trauma. Results indicate that this modified measure may be used to assess well-being at one time point or growth over two time points. Furthermore, the two items assessing spirituality had a strong relationship with each other and may be used alone in future studies.

Health Impact of US Military Service in a Large Population-Based Military Cohort: Findings of the Millennium Cohort Study, 2001-2008 BMC Public Health 2011 Jan;11(1):69

Smith TC, Jacobson IG, Hooper TI, LeardMann CA, Boyko EJ, Smith B, Gackstetter GD, Wells TS, Amoroso PJ, Gray GC, Riddle JR, Ryan MAK, for the Millennium Cohort Study Team

This report summarizes findings from the Millennium Cohort Study through 2008 that have addressed health concerns related to military service. Conducting strategic studies aimed to identify, reduce, and prevent adverse health outcomes in military members have guided public health policy and will continue to affect policy for years to come.

Associations of Military Divorce with Mental, Behavioral, and Physical Health Outcomes BMC Psychiatry 2015; 15:128

Wang L, Seelig AD, MacDermid Wadsworth S, McMaster HS, Alcarez J, Crum-Cianflone NF

This prospective study investigated the associations of recent divorce with health outcomes among US Service members. Findings indicate that recent divorce is associated with adverse mental health outcomes, including new-onset PTSD and depression, and risky behaviors, such as smoking initiation and new-onset alcohol-related problems, after adjusting for relevant demographics and covariates. Given these findings, it is important to make sure resources are available to support recently divorced Service members, since divorce may not only affect personal quality of life, but also military force readiness.

Factors Associated With Persistent Posttraumatic Stress Disorder Among U.S. Military Service Members and Veterans BMC Psychiatry 2018 Feb 17;18(1):48

Armenta RF, Rush T, LeardMann CA, Millegan J, Cooper AD, Hoge, CW

Among service members and veterans who screened positive for PTSD at baseline, 47% met the criteria for persistent PTSD. Combat experiences and PTSD severity were found to be the most salient factors associated with persistent PTSD; other associated factors included co-morbid conditions, sleep problems, and somatic symptoms. These findings corroborate the need for more comprehensive and accessible treatment to address both PTSD symptoms and comorbid conditions.

The Impact of Deployment Experience and Prior Healthcare Utilization on Enrollment in a Large Military Cohort Study BMC Medical Research Methodology 2013 Jul 11;13:90

Horton JL, Jacobson IJ, Littman AJ, Alcaraz JE, Smith B, and Crum-Cianflone NF

This study compared the characteristics of invited subjects (responders and nonresponders) prior to the enrollment cycle. Military personnel who deployed in support of OIF/OEF and those who presented for routine outpatient care were significantly more likely to enroll in a longitudinal cohort study examining their health and military experiences, while those with baseline mental disorders or longer hospital stays were less likely to enroll. These findings, which controlled for demographic and other potential confounders, suggest differential enrollment by deployment experience and health status, and may help guide recruitment efforts in future studies.

Smith B, Chu LK, Smith TC, Amoroso PJ, Boyko EJ, Hooper TI, Gackstetter GD, Ryan MAK, for the Millennium Cohort Study Team

This report highlights the importance of assessing medical conditions from multiple electronic and self-reported sources.

Assessing Nonresponse Bias at Follow-Up in a Large Prospective Cohort of Relatively Young and Mobile Military Service Members BMC Medical Research Methodology 2010 Oct;10(1):99

Littman AJ, Boyko EJ, Jacobson IG, Horton JL, Gackstetter GD, Smith B, Hooper TI, Amoroso PJ, Smith TC, for the Millennium Cohort Study Team

In this study population, nonresponse to the follow-up questionnaire did not result in appreciable bias as reflected by comparing measures of association for selected outcomes using complete case and inverse probability weighted methods.

Exploratory Factor Analysis of Self-Reported Symptoms in a Large, Population-Based Military Cohort BMC Medical Research Methodology 2010 Oct;10(1):94

Kelton ML, LeardMann CA, Smith B, Boyko EJ, Hooper TI, Gackstetter GD, Bliese PD, Hoge CW, Smith TC, for the Millennium Cohort Study Team

Using exploratory factor analysis, this study examined mental and physical health symptom covariance structure. A 14-factor model accounted for 60% of the variance indicating a reasonable amount of construct overlap and that the number and type of questions appropriately assess a spectrum of heterogeneous symptoms.

Application of Latent Semantic Analysis for Open-Ended Responses in a Large, Epidemiologic Study BMC Medical Research Methodology 2011 Oct;11:136

Leleu TD, Jacobson IG, LeardMann CA, Smith B, Foltz PW, Amoroso PJ, Derr M, Ryan MAK, Smith TC, for the Millennium Cohort Study Team

Using latent semantic analysis to analyze the final open-ended text field on the Millennium Cohort questionnaire helped identify important topic areas for future survey questions and also revealed the most common areas of concern for participants were illness and injuries, exposures, and exercise. Subjects with worse self-reported general health were more likely to provide a response in the open-ended text field than subjects with better general health.
