Postpartum Depression in a Military Sample
Postpartum depression Postpartum Depression Definition
Postpartum depression is a mood disorder that begins after childbirth and usually lasts beyond six weeks.

major depressive disorder occurring within the first 4 weeks after delivery.1 A meta-analysis of 59 studies reported an average rate of PPD of 13%,2 although some studies reported even higher rates.3 PPD has a negative impact on parenting ability4,5 and child development.6,7 Spouses of women with PPD have reported increased stress,8 may suffer psychological problems, and experience less marital satisfaction.9
There are many factors contributing to the development of PPD. Meta-analyses have identified 13 psychosocial psychosocial /psy·cho·so·cial/ (si?ko-so´shul) pertaining to or involving both psychic and social aspects.

Transitioning into motherhood is a difficult task, and this role shift may be particularly challenging for employed women. It is estimated that >50% of women with infants < 1 year of age are employed.12 Employed women may have better mental health outcomes when they take longer maternity leaves and work fewer hours per week.13 Returning to work has been found to contribute to improved mood in the postpartum period The postpartum period is the period consisting of the months or weeks immediately after childbirth or delivery. Importance to health
The postpartum period is when the woman adjusts, both physically and psychologically, to the process of childbearing. .14 des Rivieres-Pigeion et al.15 determined that social support could mediate the relationship between work status and depression, evidenced by the more isolated position of a homemaker. Professional identity may also be a source of protection against PPD,16 and employment may provide opportunities for more social support, positive feedback, fiscal autonomy, and stress management.17
Nearly 200,000 women are active duty (AD) members of the U.S. Armed Forces.18 This population has many protective factors, compared with the civilian working population. One study indicated that nearly 100% of military mothers attended check-ups during pregnancy.19 Additionally, military mothers have access to special health care services, such as diet, alcohol, and smoking counseling and infant care, exercise, and breastfeeding classes, at no cost.19
Although there are benefits to AD status, military mothers also experience unique stressors, compared with civilian mothers. A study noted that pregnant dependent spouses and AD military women reported low levels of stress but the AD women worked longer into their pregnancies and reported less support.20 They also reported more work hours per week and more weeks spent working throughout their pregnancies. Military mothers may feel especially torn between the demands of family and career.21 Additionally, struggling AD members may be hesitant to reveal emotional concerns because of fear of occupational repercussions repercussions npl → répercussions fpl

Compared with the magnitude of research on PPD and civilian women, studies focusing on military women are lacking. Research found a rate of PPD among 26 AD women of 19%.24 Another study reported that 1 1% of 109 AD mothers were positive for PPD.25 New military mothers have reported increased parenting and occupational stress.26 Additional findings indicate that parental stress among military mothers may increase family-work conflict, which may then increase depression and decrease functioning.21 When military mothers were invested and involved in each of their roles (occupational, marital, and parental), however, distress was reduced, lessening depressive symptoms.
There have been positive findings related to civilian employment and decreased PPD symptoms,15,16 but military mothers do not necessarily have the protective characteristics correlated with employment. For example, enlisted military mothers in particular may have only high school diplomas A high school diploma is a diploma awarded for the completion of high school. In the United States and Canada, it is considered the minimum education required for government jobs and higher education. An equivalent is the GED. , be single, be younger, have less support, and have more unwanted pregnancies unwanted pregnancy Obstetrics A pregnancy that is not desired by one or both biologic parents. See Teen pregnancy. .27 Alternatively, some military mothers may be less susceptible to depression because of employment-related social support and well-timed pregnancies. At this time, the literature does not appear to thoroughly address frequency or contributing factors for PPD among AD military women. This exploratory study begins to bridge the gap in the literature by examining AD military mothers and the effects of their unique employment situation on postpartum postpartum /post·par·tum/ (post-pahr´tum) occurring after childbirth, with reference to the mother.

(2) What psychosocial and demographic risk factors are associated witii PPD symptoms for military mothers? (3) Are these risk factors different from those identified in studies of civilian momers?
All AD military women, including activated reservists and activated National Guard members, who gave birth at Wilford Hall Medical Center (WHMC WHMC Wilford Hall Medical Center

Additionally, letters were not sent to mothers who had poor delivery outcomes (low Agpar scores, fetal anomalies, or deliveries before 28 weeks). This step was taken to prevent study invitations being inadvertently sent to women who might have lost their babies.
The participants completed three measures, namely, the Edinburgh Postnatal Depression Postnatal depression is a form of clinical depression which can affect women, and less frequently men, after childbirth. It is widely considered to be treatable. Studies report prevalence rates from 5% to 25%, but methodological differences among the studies make the actual Scale (EPDS EPDS Edinburgh Postnatal Depression Scale

The EPDS was developed by Cox et al.28 to aid primary care providers in detecting PPD. Its 10 items are related to PPD symptoms and requests patients to respond based on the past week. A score of 12 or 13 is a recommended cutoff value to indicate the presence of depression. A conservative cutoff value of 12 was used in this study, to avoid false-positive results and to achieve consistency with procedures in similar studies (e.g., the study by O'Boyle et al.24). The EPDS has solid reliability,30 as well as validity sensitivity and specificity.31
The PDPI-R was developed from meta-analytic findings10 as a clinician-administered interview.32 It was revised in 200229 on the basis of an updated meta-analysis" that identified 13 factors that place women at risk for PPD. Each of the statistically significant factors is represented in the original measure, that is, marital status, self-esteem, prenatal depression, prenatal anxiety, unplanned/unwanted pregnancy, history of previous depression, social support, marital satisfaction, life stress, child care stress, infant temperament, and maternity blues. The first 10 factors may be assessed both during and after pregnancy, whereas the last three are appropriate only in the postpartum period. Each question corresponds to a factor that has been found to be a statistically significant contributor to PPD.'0 " Although a recent study examined total score and cutoff value options,33 the PDPI-R was used in the present investigation to help identify exactly which risk factors may contribute to PPD in a military sample. The PDPI-R was designed for use as a clinical interview, but it has been used in a self-report format with positive results.34 We received permission from the developer (CT. Beck, personal communication) to further modify the instrument into a selfreport measure that is more amenable to statistical analyses. The modification was loyal to the original measure's 13 questions but altered the format from open-ended questions to Likert scale Likert scale A subjective scoring system that allows a person being surveyed to quantify likes and preferences on a 5-point scale, with 1 being the least important, relevant, interesting, most ho-hum, or other, and 5 being most excellent, yeehah important, etc response options.
A 22-item, multiple-choice, background questionnaire was created to identify potential characteristics associated with PPD symptoms. The items focused on military-specific and demographic variables, such as deployment status, branch of service, and rank.
Once each month, the WHMC Office of Clinical Investigations received, from the obstetrics/gynecology department chief, the names of all AD women who had given birth. Each new mother was sent an invitation letter through the Office of Clinical Investigations, informing her of the study. Informative posters and small printed materials were also displayed in the obstetrics/gynecology and pediatric pediatric /pe·di·at·ric/ (pe?de-at´rik) pertaining to the health of children.

A total of 526 women were sent letters of invitation, and an unknown number viewed the study posters. Ninety-two responded and participated in the study. Four participants did not complete the measures, and one mother participated past the 6-month time period; these five women were excluded from analysis. A total of 87 participants were included in data analysis. Participants completed measures an average of 11 .7 weeks after delivery.

Therefore, Spearman's ? analyses (two-tailed) were conducted with 12 of the 13 factors on the PDPI-R. Analyses indicated significant positive correlations between 10 of these items and scores on the EPDS (Table IV). Marital status was analyzed by using Pearson's ?^sup 2^ tests. The analysis showed that one cell had an expected count of <5; therefore, an exact significance test was selected. There was no relationship between marital status and EPDS scores (?^sup 2^ = 0.038, df = , exact p = 1.000).

This study found a rate of PPD in an AD military sample of nearly 20%. This value is consistent with findings in another military sample.24 Although the rate it is elevated in comparison with averages in the civilian population, it is within the range reported in various other studies.3 It is unclear what contributing factors might be responsible for an increased rate of PPD symptoms in this sample. Some studies have suggested that neither employment status36 nor occupation type2 is an important variable related to PPD. This sample was drawn from patients at a large hospital known for its treatment of complicated pregnancies; it is interesting to highlight that nearly 40% of this sample endorsed complications, a factor noted for its contribution to PPD.37 The elevated rate may also reflect a unique struggle AD mothers face; one study found that 51 % of military women indicated a belief that there is no ideal time to have both children and a military career.27 Other investigators reported that ~25% of women who chose to leave the military identified work-family conflict Work-family conflict is “a form of interrole conflict in which the role pressures from the work and family domains are mutually incompatible in some respect. That is participation in the work (family) role is made more difficult by virtue of participation in the family (work) as a reason for separation.38 It is possible that our sample subjects struggled with such concerns, which were not directly assessed in this study.
Ten psychosocial factors were associated with PPD, including low self-esteem, prenatal anxiety, prenatal depression, history of previous depression, social support, poor marital satisfaction, life stress, child care stress, difficult infant temperament, and maternity blues. Three factors were not, including income level, marital status, and unplanned pregnancy, which is consistent with the meta-analysis by Beck," in which the same factors had only small effect sizes, whereas the other 10 had moderate effect sizes.
Particularly interesting is the lack of association between PPD and military-specific factors. Women who were in a dual-military relationship were not at higher risk for PPD. Additionally, women who were dealing with an impending im·pend

b. with their lifestyle. Additionally, if pregnant enlisted members find the military environment incompatible with motherhood, they may request discharge.39 As previously stated, health care and supportive programs for military families during and after pregnancy are comprehensive and may actually serve as protective factors against PPD. However, military-specific environmental features that were not assessed could actually be affecting the 10 identified risk factors. Perhaps life stress could be accounted for by occupational stress, marital satisfaction might be affected by military lifestyle, or child care stress might be affected by long work hours.
This study has generated information that may help identify military mothers who have or are at risk for PPD. Although some military hospitals, such as this data collection site, assess and actively treat women with PPD, these results indicate it is imperative for other military bases to continue using, or consider adopting, such a protocol. It is interesting to note that all of the women in this study had already been given the EPDS during their obstetrics/gynecology visits and were automatically referred for treatment if they scored a 12. This sample's rate of PPD was nearly 1 in 5, despite the fact that each woman had already been screened for PPD. Other military health care facilities without this procedure could have particularly high rates of undiagnosed and untreated PPD.
Understanding factors that contribute to PPD in AD women can also lead to more effective prevention and intervention efforts. Although some military members are hesitant to disclose the presence of emotional distress emotional distress n. an increasingly popular basis for a claim of damages in lawsuits for injury due to the negligence or intentional acts of another. Originally damages for emotional distress were only awardable in conjunction with damages for actual physical harm. because of stigma or fear of occupational consequences,22,23 knowing the risk factors can alert health providers to further assess the presence of PPD when a mother presents with significant factors. Identification and treatment of PPD could improve the quality of life and the quality of health care for military service members. Reduced costs to the government resulting from lost time and poor work quality may also be a positive result.
This study's method is an example of how technology can be used to gather data from special populations. Online data were collected while the primary investigator was residing thousands of miles away from the collection site, but the investigators were still able to safeguard the data until conclusion of the study (at which time it will be destroyed). Additionally, the completely anonymous nature of the method provided the opportunity for military women to disclose more information than they might be comfortable doing with their health care providers.22,23 This research displays a confidential methodological standard for gathering and safeguarding sensitive information.
There are several limitations in this work, largely attributable to the exploratory nature of the study. The psychosocial risk factors were measured only through single-question Likert scale items, and the presence or absence of risk factors was not fully assess. It was not feasible to investigate these factors with individual measures because of the time required and expense, as well as difficulty recruiting mothers with spare hours for study participation. Additionally, the PDPI-R was originally developed as a screening tool for identifying women at risk29 and was appropriate for rapid identification of risk factors in this sample. Furthermore, it is important to consider the correlational nature of this study, noting that causation cannot be inferred. Although "risk factors" are discussed, it is not clear whether these factors are present before PPD or arise as a result of the disorder. For example, poor marital satisfaction could occur after onset of PPD or contribute to its development.
It is also important to note that our sample may not accurately reflect the military population as a whole, because a single site was the source of all data collected and the sample size was relatively small. This sample also reflected over-representation of military officers (nearly 40%), compared with the female U.S. Air Force population of ~80% enlisted personnel and ~20% officers.40 As stated previously, rank did not statistically significantly distinguish depressed from nondepressed participants. More than one-half of the married/partnered women were in dual-military relationships. However, there were also no detectable differences related to spouse status. Approximately one-third of the sample subjects were serving their first term in the military, which also indicates greater participation of more seasoned military members than might be expected. It is also interesting to note that more than one-half of the participants were multiparous; some researchers have found that parity is important, because multiparous women may be more vulnerable to PPD.41 Although many women with medical complications participated, our letter-based advertising did exclude women with poor outcomes, which also could have biased our results. Finally, these participants were self-selected and might have chosen to respond to advertisements because of personal concerns related to the study topic.
Our response rate was -17.5%. It is not known whether mothers solicited in person would have been more participative than those solicited by letter. However, the burden of advertising/soliciting was greatly reduced by mailing a letter, rather than requesting military medical staff members to discuss the study witii women at the time of their delivery/ postpartum follow-up visits. Additionally, the primary investigator was residing thousands of miles away from the collection site. The completely anonymous nature of the study was also viewed as a benefit of letter-based recruitment.
Future studies should focus on multiple sites, larger sample sizes, and additional methods for assessing risk and protective factors. Expanded military-specific questions would better examine the effects of the military environment and wartime status on mothers' mental health. Work-family conflict should be considered in this population as well. It would helpful to identify any differences related to branch of service, as well as the unique circumstances that activated reservist re·serv·ist

Length of time in service, parity, and adverse outcomes/pregnancy complications are also worthwhile factors to investigate.

In conclusion, the reported findings of our study may allow for more targeted prevention and treatment of PPD in a military setting. There are identification and treatment protocols at certain military hospitals, such as WHMC. Such procedures involve screening all pregnant women before delivery (at 32-36 weeks) and 6 weeks after delivery and allowing doctors and nurses to make referrals to a behavioral health Behavioral health was first used in the 1980's to name the combination of the fields mental health and substance abuse. As an example, an organization serving both mental health and substance abuse clients might refer to its practice as behavioral health or consultant in the obstetrics/gynecology department.42·43 Expanding specialized behavioral health consultant services, along with this knowledge of risk factors, could help increase effective identification and treatment delivery for military women at risk for PPD.
