The perinatal period is increasingly recognized as a vulnerable time for the development and exacerbation of psychopathology symptoms. Research has often focused on perinatal depression, with limited information on perinatal anxiety. This study examined the psychometric structure of all anxiety and depressive disorder symptoms as well as explored the relation between perinatal internalizing symptoms and sociodemographic, obstetric, and psychological risk factors. Obsessive-Compulsive Disorder (OCD) is a common perinatal anxiety disorder that is now classified with the Obsessive-Compulsive Spectrum (OCS) (hoarding, body dysmorphic, trichotillomania, and excoriation disorders). This study also aimed to determine the prevalence of clinically significant OCS symptoms and their association with postpartum adjustment. Participants recruited from the University of Iowa Hospitals and Clinics (N =246) completed an online questionnaire and a structured clinical interview during pregnancy (28-32 weeks gestation) and the postpartum (6-8 weeks). Questionnaires assessed demographics, pregnancy complications, anxiety sensitivity, coping strategies, maternal attitudes and experiential avoidance. Clinical interviews dimensionally assessed all anxiety and depressive symptoms as well as past psychiatric diagnoses. Confirmatory factor analyses identified three factors: Distress (depression, GAD, irritability, and panic); Fear (social anxiety, agoraphobia, specfic phobia, and OCD); and Bipolar (mania and OCD) during pregnancy and the postpartum. During pregnancy, structural equation modeling demonstrated that past psychiatric history predicted Distress and Fear symptoms. Experiential avoidance mediated the relation between negative coping strategies and Fear symptoms. In the postpartum, negative maternal attitudes predicted Distress symptoms. Experiential avoidance mediated the relation between negative coping strategies and Fear symptoms as well as between anxiety sensitivity and Fear symptoms. There were low rates of clinically significant OCS symptoms, except for body dysmorphic disorder symptoms. Elevations in all OCS disorder symptoms were significantly associated with more difficulty adjusting to the postpartum. Past psychiatric history, negative maternal attitudes, and experiential avoidance are particularly important risk factors for perinatal anxiety. Future clinical research should be aimed at identifying at-risk women and modifying experiential avoidance during the perinatal period. Elevated OCS symptoms, particularly body dysmorphic disorder symptoms, affect postpartum adjustment. Future intervention work should focus on assessing and treating perinatal body dysmorphic disorder symptoms.

BACKGROUND: Both mood and anxiety disorders are more prevalent in women than men with the onset typically occurring during adolescence or early childbearing years. These disorders are particularly prevalent during pregnancy and the postpartum period. While depression during the perinatal period has received significant attention recently, anxiety has not received the same amount of attention. METHODS: The current study was a secondary analysis of a prospective cohort study that followed 91 women with mood disorders through pregnancy and the postpartum period. Our objective was to determine if a correlation existed between anxiety and suicidality. We hypothesized that pregnant women with a history of a mood disorder and comorbid anxiety are more likely to be suicidal than those without comorbid anxiety. The presence of anxiety was determined using the anxiety subscale of the Edinburgh Postnatal Depression Scale, EPDS; a cut off score of six or greater was used to indicate significant anxiety. Suicidality was determined using three separate measures: question ten on the EPDS, question eighteen on the Inventory of Depressive Symptomatology, and question ten on the Montgomery-Asberg Depression Rating Scale. ANALYSIS: Chi square tests were used to compare the demographics of the anxious and non-anxious women based on both diagnosis of anxiety disorders and symptoms of anxiety. Z proportion tests were then used to compare the proportion women with anxiety versus those without anxiety who were suicidal. Lastly, binary logistic regression was used to determine if patients with anxiety were more likely to be suicidal. RESULTS: Among the women in this study, 62 (68.1%) had a diagnosis of major depressive disorder and 29 (31.9%) had a diagnosis of bipolar disorder based on DSM-IV-TR diagnostic criteria. In addition, 45 (49.5%) had a lifetime history of an anxiety disorder. The prevalence of significant anxiety symptoms, as determined by the anxiety subscale on the EPDS, ranged from 9.1-37.5% depending on the time point. Suicidality prevalence also varied depending on both the time point and the scale used: 0-17.5% using the MADRS, 6.7-24.7% using the EPDS, and 2.4-14.7% using the IDS. Using a binary logistic regression, we determined that anxiety was a risk factor for suicidality at time T3 (OR 2.106; 95% CI 1.274-3.481) and M1 (OR 2.057; 95% CI 1.179-3.586) on the MADRS and at T3 (OR1.758; 95% CI 1.219-2.535) on the EPDS.

Background: Antenatal Psychosocial Assessment (APA) has recently been introduced into routine antenatal care, but the ways in which maternity service providers assess and respond to maternal stress are subject of debate. There is a lack of consensus on the instrument(s) of choice and lack of evidence regarding appropriate interventions. Further, national guidelines have not kept apace with the conceptual shift from ‘postnatal depression’ to ‘perinatal anxiety and depression’. Adopting the Medical Research Council Complex Interventions Framework, the ARMS research aimed to inform the development of interventions that support women who are experiencing, or at risk of, mild-moderate mental health disorder in pregnancy. Methods: A mixed methods approach was adopted. In the quantitative element (Study Part 1) participants (n=191) completed a questionnaire when attending for their first formal antenatal appointment, using a procedure and materials that had been previously tested in a pilot study. Details including mental health assessment and referrals were obtained from their health records, following delivery. In the qualitative element (Study Part 2) a sub-sample of women (n=22) experiencing high levels of maternal stress took part in up to three serial in-depth interviews during pregnancy and the early postnatal period.Findings: Maternal stress was found to be common. Using the Edinburgh Postnatal Depression Scale (EPDS) threshold of ≥10, approximately 1 in 4 women were classed as high depression (halving to 1 in 8 at the more conservative threshold of ≥13). Almost 1 in 3 women were classed as high anxiety, using the state scale of the State-Trait Anxiety Inventory (STAI-S, threshold ≥41), compared with 1 in 5 using the two-item GAD (threshold ≥3). Fewer than half of the women identified as high anxiety were identified by both measures. Factor analyses of the symptom measures were consistent with wider literature suggesting a three-item anxiety component of the EPDS; however, concurrent validation using regression analyses did not indicate that the EPDS could be used as an anxiety case finding instrument. Women reported that maternal stress had significant impact on their lives that may not be captured with existing clinical approaches. Women commonly found it difficult to self-assess severity of maternal stress and the assessment process could itself act as an intervention. The research provided the first validation of the depression case finding questions in UK clinical practice. The Whooley items completed in clinical practice identified only half of the possible cases identified by the EPDS, at both commonly adopted EPDS thresholds. Inclusion of the Arroll 'help' question as a criterion improved specificity of the assessment completed in clinical practice but substantially compromised sensitivity, missing 9 in 10 possible cases. Women’s mental health history and treatment history were similarly under-reported, particularly concerning anxiety. APA was introduced into routine clinical practice without attention to topics of relevance to women, context of disclosure or to provision of adequate resources for consistently responding to identified need. Women experiencing, or at risk of, mild-moderate disorder were thus usually ineligible for further support. Implications: Care pathways are needed that encompass both assessing and responding to maternal stress, where communication with health professionals, subsequent referral and management are addressed. The development, implementation and evaluation of low-cost resources embedded in such pathways are a priority and the research presented in the thesis offers a foundation on which to build.
