JOGNN Evidence-Based Recommendations for Depressive Symptoms in Postpartum Women Karen McQueen1, Phyllis Montgomery2, Stephanie Lappan-Gracon3, Marilyn Evans4, and Joanne Hunter5

ABSTRACT Correspondence Karen McQueen, RN, MA(N), School of Nursing, Lakehead University, 955 Oliver Road, Thunder Bay, Ontario, Canada, P7B 5E1. [email protected]

Postpartum depression is a serious health issue affecting 13% of women from diverse cultures. Despite the welldocumented consequences of postpartum depression, it remains difficult to identify, and diverse practices relate to its prevention and treatment. Evidence-based interventions are essential to improve both maternal and infant health outcomes associated with pregnancy. This article describes the development process of an evidence-based practice guideline for postpartum depression and highlights the practice recommendations related to the confirmation, prevention, and treatment of depressive symptoms in postpartum mothers.

The panel recommends the EPDS in

The main difference was Gaynes et al.’s (2005) inclusion criteria that specified a clinical assessment or structured clinical interview to confirm depressive symptoms. Boyd et al.

Ease of administration, acceptability by different cultures, international recognition, and availability at no cost were identified as supportive for the clinical applicability of the EPDS (Dennis, 2003a).

For the majority of women, the onset of depression usually occurs within the first few weeks or months after delivery (Cooper, Campbell, Day, Kennerley, & Bond, 1988; Goodman, 2004; McIntosh, 1993; Small, Brown, Lumley, & Astbury, 1994). However, for some mothers, the inception of depressive symptoms occurred after 12 weeks (Small et al., 1994) and others much later between 6 and 12 months (Cooper et al., 1988).

repeatedly applying the EPDS to assist with assessment. The validity, sensitivity, and specificity of repeated use with a postpartum mother are unknown. Recommendation 5. Nurses encourage postpartum mothers to complete the EPDS tool by themselves in privacy (Level of Evidence = III). Current research suggests that EPDS scores are more reliable when mothers complete the EPDS alone, without others present (Cox & Holden, 2003).

(Level of Evidence = III).

Research has demonstrated that the EPDS is most effective in the confirmation of depressive symptoms (sensitivity and specificity) when the recommended cutoff score of greater than 12 is used in the postpartum period among English-speaking mothers in the U.K. (Cox et al., 1987), Canada (Zelkowitz & Milet, 1995), and Australia (Boyce et al., 1993). An EPDS score greater than 12 does not mean a mother has postpartum depression, nor does a score translate into the severity of depressive symptoms (Cox & Holden, 2003). Conversely, a score of 11 does not indicate that the mother is not experiencing emotional distress particularly when the health professional has identified concerns. Rather, an EPDS score indicates the mother’s perception of her mood. In addition, different cutoff scores may be required for

The clinical use of the EPDS is not intended to replace health professionals’ comprehensive assessment of a mother/family during the postpartum period. Instead, the guideline recommends that the EPDS be used as an adjunct to clinical evaluation. Elliott and Leverton (2000) emphasize that when used alone, “the EPDS is just a piece of paper, a checklist” (p. 305). When combined with knowledge in prevention, identification, and treatment of postpartum depression, however, the EPDS can facilitate discussion about needs, family and role transitions, and supports (Cox & Holden, 2003; Lundh & Gyllang, 1993). Additionally, the EPDS may be used as a means of identifying improving or worsening symptoms and to assist decision making regarding engaging support systems, providing postpartum depression information, and referring and securing treatment.

Hwang, 1996). For women experiencing severe depression, other treatments are often required. The degree of depression alone is not the sole indicator of a specific intervention (such as medication, cognitive behavioral therapy, or interpersonal psychotherapy); rather, treatment based on maternal needs and preferences is the guiding principle (Holden, 1996).

cidal ideation (Morris-Rush, Freda, & Bernstein, 2003). Depression is a major risk factor for suicide, and any positive score (1-3) related to suicidal ideation or selfharm must be further assessed in a timely manner. Although various suicide assessment scales are available for use in practice, the developers of the EPDS recommend additional questions for assessment (see Table 4). Agency policies and procedures must be in place to assist health providers with decision making in the plan of care for mothers who score positive on self-harm (Cox & Holden, 2003). Treatment Recommendations.

More recent findings also provide additional support for the effectiveness of diverse treatments for postpartum depression. In particular, British Medical Journal ’s Clinical Evidence search and appraisal identified cognitive behavioral therapy, interpersonal therapy, and nondirective counseling as likely to be effective nondrug treatments for postpartum depression (Howard, 2006). Similarly, Bledsoe and Grote’s (2006) preliminary metaanalysis found diverse interventions to be effective for treating nonpsychotic major depression during pregnancy and postpartum. Their research involved 16 treatment trials with 922 participants, which assessed treatment effects during pregnancy (3 trials) and the postpartum period (13 trials). However, their findings

When used as a screening tool to identify depressive

Additionally, much of the research on prevention has concentrated on the primary prevention (activities that will help prevent a certain condition) of postpartum depression. However, secondary prevention strategies (activities targeted toward specific subgroups expected to be at higher risk for a problem, with the aim to slow or interrupt the progress of the condition through early detection and treatment; RNAO, 2005) are also very important. Current evidence supports the significance of postpartum depressions screening for early detection and treatment of symptoms (Boyd et al., 2005; Freeman et al., 2005; Horowitz & Cousins, 2006). Therefore, training health professionals to identify women with depres-

symptoms, the EPDS provides a relatively rapid measure of emotional distress, which is easily interpreted by clinicians (Mosack & Shore, 2006; Sharp & Lipsky, 2002), and it is easy to administer, requiring little time and training (Cox & Holden, 2003). However, its usefulness is partly dependent on the clinician’s understanding of its specific purpose and limitations. Thus, the EPDS is neither a diagnostic instrument nor a substitute for a diagnostic assessment. Instead, the EPDS is intended to provide severity of symptoms information and should be used as an adjunct to a thorough assessment of the emotional needs of the new postpartum mother.

Finally, a potential criticism of the EPDS-related recommendations may be the timing or intervals of EPDS administration, as no one best time to screen has been identified. As a result, it is challenging for clinicians or decision makers to specify an optimal time for administration. However, this should not be considered a serious limitation of the EPDS as the timing of administration question exists with any tool used to assess for postpartum depressive symptoms.

Malone, 2004). Therefore, describing the rigorous process used to develop the guideline and actively promoting the dissemination of the recommendations in a concise, easy to use, and accessible manner such as this article may have the potential to increase the uptake of evidence-based care and ultimately improve outcomes for mothers with postpartum depression. Finally, the guideline while conceptualized within the scope of nursing practice can be used by various health care providers caring for postpartum mothers.
