Background: Mental health disorders are the most prevalent health complication experienced during pregnancy and the postpartum, with anxiety disorders being most common. Intolerance of uncertainty (IU) is a well-known feature of anxiety disorders and has recently been identified as a risk factor for the worsening of anxiety during the postpartum period. Cognitive Behavioural Therapy (CBT) is a first-line treatment for perinatal anxiety, and CBT specifically targeting IU in non-perinatal populations has demonstrated positive findings for reducing anxiety. As such, the objective of our study is to examine whether CBT targeting IU in pregnancy can reduce the risk of postpartum anxiety. Methods: This protocol paper outlines a proof-of-concept randomised clinical trial assessing the effectiveness of a newly developed CBT for IU (CBT-IU) protocol to reduce the risk of postpartum anxiety. Pregnant individuals identified at increased risk for postpartum anxiety (defined as a baseline score of 64 or greater on the Intolerance of Uncertainty Scale) will be randomised to receive CBT-IU or care as usual (CAU) during pregnancy and will be followed through the postpartum period (6-12 weeks). The CBT-IU protocol is a weekly, six session treatment, which includes psychoeducation, behavioural experiments, imaginal exposure, and problem-solving to target IU. Discussion: To our knowledge, this will be the first study to investigate the efficacy of a CBT protocol aimed at reducing the risk of developing postpartum anxiety. Establishing this protocol as a potentially preventative strategy will offer a new option to improve the mental health and well-being of mothers and their infants.

Generalized anxiety disorder (GAD) is common during the perinatal period. Since its inception, substantial efforts have been put forth to improve the specificity and interrater reliability of GAD. More recently, increased attention has been given to the behavioral features of GAD, with evidence to suggest that hypervigilance, checking, and avoidance may be particularly relevant. It is unknown however if these behaviors lead to improved classification and understanding of GAD. The present study examines: (1) the proportion of perinatal individuals with and without GAD who endorse hypervigilance, checking and avoidance; (2) interrater reliability of GAD during the perinatal period; (3) whether inclusion of hypervigilance, checking, and avoidance in GAD diagnostic criteria leads to improved interrater reliability; and (4) if hypervigilance, checking and avoidance significantly predict GAD diagnostic status beyond current features of the disorder. Thirty-eight perinatal women, who were predominantly white and highly educated were randomized to one of two assessors to complete a semi-structured diagnostic assessment. Interviewers queried about the presence of current mental health disorders and engagement in behaviors of interest. Each assessment was independently rated by three assessors. More participants with GAD reported engaging in hypervigilance, checking, and avoidance than those without GAD. Interrater agreement of GAD diagnoses was excellent (κ = 0.91). Inter-rater agreement of GAD diagnoses was comparable (κ = 0.92) when checking was included in the diagnostic criteria of GAD. Checking also significantly predicted GAD diagnostic status beyond existing features of the disorder. These results support continued evaluation of the role of checking in GAD.

Background Cognitive behavioural therapy (CBT) has been shown to be effective for several psychiatric and somatic conditions; however, most randomized controlled trials (RCTs) have administered treatment in person and whether remote delivery is similarly effective remains uncertain. We sought to compare the effectiveness of therapist-guided remote CBT and in-person CBT. Methods We systematically searched MEDLINE, Embase, PsycINFO, CINAHL, and the Cochrane Central Register of Controlled Trials from inception to July 4, 2023, for RCTs that enrolled adults (aged ≥ 18 yr) presenting with any clinical condition and that randomized participants to either therapist-guided remote CBT (e.g., teleconference, videoconference) or in-person CBT. Paired reviewers assessed risk of bias and extracted data independently and in duplicate. We performed random-effects model meta-analyses to pool patient-important primary outcomes across eligible RCTs as standardized mean differences (SMDs). We used Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidance to assess the certainty of evidence and used the Instrument to Assess the Credibility of Effect Modification Analyses (ICEMAN) to rate the credibility of subgroup effects. Results We included 54 RCTs that enrolled a total of 5463 patients. Seventeen studies focused on treatment of anxiety and related disorders, 14 on depressive symptoms, 7 on insomnia, 6 on chronic pain or fatigue syndromes, 5 on body image or eating disorders, 3 on tinnitus, 1 on alcohol use disorder, and 1 on mood and anxiety disorders. Moderate-certainty evidence showed little to no difference in the effectiveness of therapist-guided remote and in-person CBT on primary outcomes (SMD −0.02, 95% confidence interval −0.12 to 0.07). Interpretation Moderate-certainty evidence showed little to no difference in the effectiveness of in-person and therapist-guided remote CBT across a range of mental health and somatic disorders, suggesting potential for the use of therapist-guided remote CBT to facilitate greater access to evidence-based care.

Generalized anxiety disorder (GAD) is a leading mental health concern during pregnancy and the postpartum (perinatal) period. People with GAD engage in problematic behaviors to manage their distress. However, the extent of GAD behaviors during the perinatal period may not be adequately captured by the Worry Behaviors Inventory (WBI), the most comprehensive measure of GAD behaviors to date. We evaluated the structure of the initial WBI item-pool and then evaluated the internal consistency, construct validity, and predictive utility of the Perinatal Revised WBI (WBI-PR) in a sample of 214 perinatal women with and without GAD. A two-factor, 10-item scale was supported, and some of the retained items differed from the original WBI. Internal consistency of the WBI-PR was acceptable, and evidence of construct validity was demonstrated. The WBI-PR predicted GAD diagnostic status both alone and beyond existing generalized anxiety and depression symptoms. Implications of these findings are discussed.

Background: One in five pregnant and postpartum individuals experience an anxiety, depressive, and/or trauma-related disorder. Emotion dysregulation (ED) underlies the development and maintenance of various mental health disorders. The Difficulties in Emotion Regulation Scale (DERS) is the most comprehensive and commonly used measure of emotion dysregulation, yet limited evidence supports its use in the perinatal population. The present study aims to evaluate the validity of the DERS and its six subscales in a perinatal sample and to assess its predictive utility in identifying perinatal individuals with a disorder characterised by emotion dysregulation. Methods: Pregnant and postpartum individuals (N = 237) completed a diagnostic clinical interview and self-report measures of anxiety, depression, and perceived social support. Results: The DERS subscales demonstrated good internal consistency and construct validity, as it strongly correlated with measures of anxiety and depression and failed to correlate with a measure of perceived social support. Results from an exploratory factor analysis supported a 6-factor solution, suggesting structural validity. An ROC analysis revealed good to excellent discriminative ability for the DERS full scale and four of the subscales. Finally, an optimal clinical cut-off score of 87 or greater was established with a sensitivity of 81% for detecting a current anxiety, depressive, and/or trauma-related disorder. Conclusions: This study provides evidence for the validity and clinical utility of the DERS in a treatment-seeking and community sample of pregnant and postpartum individuals.

Background: Generalized anxiety disorder (GAD)-characterised by excessive and uncontrollable worry-is the most frequently diagnosed anxiety disorder during pregnancy and the postpartum period. Identification of GAD often relies on assessment of its cardinal feature, pathological worry. The Penn State Worry Questionnaire (PSWQ) is the most robust measure of pathological worry to date but has not been extensively evaluated for use during pregnancy and the postpartum period. This study evaluated the internal consistency, construct validity, and diagnostic accuracy of the PSWQ in a sample of pregnant and postpartum women with and without a principal GAD diagnosis. Methods: One hundred forty-two pregnant and 209 postpartum women participated in this study. Sixty-nine pregnant and 129 postpartum participants met criteria for a principal diagnosis of GAD. Results: The PSWQ demonstrated good internal consistency and converged with measures assessing similar constructs. Pregnant participants with principal GAD scored significantly higher on the PSWQ than those with no psychopathology and postpartum participants with principal GAD scored significantly higher than those with principal mood disorders, other anxiety and related disorders, and no psychopathology. A cut-off score of 55 and 61 or greater was determined for detecting probable GAD during pregnancy and the postpartum period, respectively. Screening accuracy of the PSWQ was also demonstrated. Conclusions: This study underscores the robustness of the PSWQ as a measure of pathological worry and probable GAD and supports its use in the detection and monitoring of clinically significant worry symptoms during pregnancy and postpartum period.

Generalized anxiety disorder (GAD) is one of the most common anxiety disorders in pregnancy and the postpartum (perinatal) period. Perinatal women with GAD engage in problematic behaviours, yet the focus and function of these behaviours remain unknown. Objective Given that worry during the perinatal period is largely maternally focused, the objective of this study was to explore the accompanying behavioural features of GAD during pregnancy and the postpartum period. Design A qualitative study was conducted. Methods Twenty‐five pregnant (n = 10) and postpartum (n = 15) women were recruited through clinical referrals and the Hamilton community. Following the completion of a semistructured diagnostic interview and symptom measures, participants participated in one of seven focus groups to learn about behaviours utilized in response to their worries. A thematic analysis was conducted to identify behaviour themes and subthemes in pregnant and postpartum women. Results Five behaviour themes and 12 subthemes were identified. Specifically, participants endorsed engaging in excessive reassurance seeking, checking and repeating, overcontrol, overpreparation and avoidance behaviours. Conclusions Our results confirm that perinatal women with GAD engage in comparable problematic behaviours to those with GAD in the general population, yet the presentation, frequency and focus of those behaviours differ. These findings have implications for theoretical formulations of GAD, and the clinical management of this disorder during the perinatal period.

The novel COVID pandemic has had a substantial impact on global mental health, including those populations that are inherently vulnerable such as pregnant and postpartum (perinatal) women. Anxiety disorders (ADs) are the most common mental health disorders during the perinatal period, affecting up to one in five women. However, since the onset of the pandemic, up to 60% of perinatal women are experiencing moderate to severe levels of anxiety. Given the substantial increase in perinatal anxiety during COVID, we sought to better understand its phenomenology by characterizing the collective worry content and impact of COVID using a content analysis. Eighty‐four treatment‐seeking pregnant (n = 35) and postpartum (n = 49) women with a principal AD, participated in this study between April and October 2020. In addition to completing questionnaire measures and a semistructured diagnostic interview, participants were asked to (1) describe their top excessive and uncontrollable worries, (2) describe additional COVID and non‐COVID worries, and (3) describe how the pandemic had affected their lives. All responses were given verbally and transcribed verbatim by assessors. A content analysis led to the emergence of various COVID and non‐COVID worry and impact themes. One third of participant's principal worries were specific to COVID, and 40% of COVID worries were specific to the perinatal context. Understanding the worry content and impact of COVID may improve symptom detection and inform the development of targeted treatment strategies to support the mental health needs of perinatal women with ADs throughout the pandemic and thereafter. Understanding pandemic‐specific worries is important for perinatal symptom screening and may allow for the development of targeted treatment strategies to address COVID‐specific worries and impact.

The perinatal period is considered a window of vulnerability given the increased risk of psychiatric difficulties during this time, such as mood and anxiety disorders (ADs). Pre-pandemic rates of ADs in perinatal women were one in five but have since increased with the onset of the COVID-19 pandemic (COVID). In addition, recent research suggests that the focus of worry has shifted during the pandemic, with perinatal women reporting significantly more COVID-specific worries. The objective of this study was to augment our current evidence-based Cognitive Behavioural Group Therapy (CBGT) for perinatal anxiety protocol by targeting intolerance of uncertainty and tailoring existing strategies to address COVID-related worry and impact. Pregnant (n = 19) and postpartum (n = 49) women were recruited from regular clinic patient flow from a university-affiliated teaching hospital between September 2020 and March 2021. Improvements in generalized anxiety symptoms, worry, intolerance of uncertainty, and mood were observed at post-treatment, maintained at 3-months, and the intervention received high ratings of treatment satisfaction. This is the first study to examine an augmented CBGT for perinatal women with GAD during the pandemic and supports the inclusion of strategies that target intolerance of uncertainty as well as specific pandemic and perinatal worry content for effective outcomes.
