ABSTRACT

Psychological distress is the most common complication of pregnancy. High-risk concerns can include severe emotion dysregulation, suicidality and self-injury, and health risk behaviours, which bear substantial consequences for caregivers and families. Yet, effective, comprehensive interventions for high-risk caregivers have received limited attention. Dialectical behaviour therapy (DBT) is a frontline treatment for such concerns. Accordingly, we conducted a scoping review on the implementation of DBT in the perinatal period. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Seven studies were identified; study designs included case studies and single-arm pilot trials. Most studies used DBT-informed protocols with significant adaptations, few included multiple components of DBT (i.e. skills group, individual therapy, phone coaching and consultation team), and none met criteria for adherent delivery of all four modes of DBT treatment. Findings suggest DBT-informed interventions may be successfully implemented to treat a range of perinatal mental health symptoms, including borderline personality disorder, depression, anxiety, and post-traumatic stress, and to promote emotion regulation and positive parenting behaviours. While results provide preliminary support for perinatal DBT, this literature is scant and empirical rigour considerably lacking. Clinical implications and future directions are outlined to aid researchers and providers in addressing the ongoing perinatal mental health crisis and developing sorely needed interventions to address the needs of high-risk caregivers.

ABSTRACT

Background: Acceptance and commitment therapy (ACT) has been shown to promote willingness to experience intrusive thoughts among individuals with obsessive-compulsive disorder (OCD). Exposure with response prevention (ERP) delivered from an ACT framework (i.e., ACT+ERP) may facilitate changes in how patients relate to their unwanted internal experiences.Aims: Accordingly, the present study aimed to examine the effect of ACT+ERP on appraisals of intrusive thoughts, relative to standard ERP.Methods: Forty-eight adults who received 16 treatment sessions as part of a randomized controlled trial comparing standard ERP to ACT+ERP completed the Interpretation of Intrusions Inventory (III) at pre-treatment, post-treatment, and follow-up.Results: Results showed a significant main effect of time for all III subscales, suggesting that appraisals of intrusive thoughts shift over the course of treatment. The effect of the condition × time interaction, however, differed between the III subscales. Specifically, a significant interaction emerged for the control of thoughts subscale, such that individuals who received ACT+ERP experienced greater reductions in beliefs about the need to control thoughts. The interaction term was not significant for importance of thoughts or responsibility subscales.Conclusions: Findings suggest that augmenting ERP with ACT enhances change in beliefs about the need to control thoughts, but not in beliefs about responsibility and the importance of thoughts. Clinical implications and future research directions will be discussed.

ABSTRACT

BACKGROUND: Obsessive-compulsive disorder (OCD) is associated with particular cognitive processes, such as beliefs about the importance of intrusive thoughts. The present study examined the explanatory power of guilt sensitivity to OCD symptom dimensions after controlling for well-established cognitive predictors. METHODS: 164 patients with OCD completed self-reported measures of OCD and depressive symptoms, obsessive beliefs, and guilt sensitivity. Bivariate correlations were examined, and latent profile analysis (LPA) was used to generate groups based on symptom severity scores. Differences in guilt sensitivity were examined across latent profiles. RESULTS: Guilt sensitivity was most strongly associated with unacceptable thoughts and responsibility for harm OCD symptoms, and moderately with symmetry. After controlling for depression and obsessive beliefs, guilt sensitivity added explanatory power to the prediction of unacceptable thoughts. LPA identified 3 profiles; profile-based subgroups significantly differed from one another in terms of guilt sensitivity, depression, and obsessive beliefs. CONCLUSIONS: Guilt sensitivity is relevant to various OCD symptom dimensions. Above and beyond depression and obsessive beliefs, guilt sensitivity contributed to the explanation of repugnant obsessions. Theory, research, and treatment implications are discussed.

ABSTRACT

Reproductive coercion (RC) can be conceptualized as any behavior that limits one's ability to make decisions about their reproductive health. Here, we broaden this definition to consider the impact of systemic and sociocultural factors on RC using an ecological model. Specifically, we use Bronfenbrenner's model as a framework for organizing the multilevel factors that influence reproductive coercion (RC) and its impacts on individual health. This paper is intended to offer a primer to historical, sociocultural, community, interpersonal, and individual processes that may interact to shape reproductive decision-making and its effect on individual health outcomes. We emphasize the importance of conceptualizing RC within the broader sociocultural and community context, and the potential implications for reproductive and sexual health research, clinical care, and policy in the United States.

ABSTRACT

The COVID-19 pandemic has presented many stressors for parents. This study was conducted to examine treatment preferences and barriers to care amidst COVID-19. Parents (N â€‹= â€‹95) completed self-report measures. Education was provided on interventions (e.g., individual therapy, medication), and acceptability assessed. Elevated stress and distress were observed. Parents indicated interest in services for parenting concerns, stress, anxiety, and depression. Individual therapy and telehealth were highly acceptable, while medication and group therapy were less accepted. Findings highlight the need for specific supports among parents amidst the pandemic. Factors that influence treatment preference warrant further attention. Implications for healthcare service delivery are discussed.

ABSTRACT

BACKGROUND: Cognitive bias theories propose that reducing threat hypervigilance in mental disorders can augment cognitive behavioral therapy (CBT) outcomes. However, no studies have tested whether adding attention bias modification (ABM) can effectively enhance CBT's effects on anxiety sensitivity (AS), electromyography (EMG), and skin conductance (SC) for panic disorder (PD). This pilot randomized controlled trial (RCT) thus aimed to evaluate the efficacy of CBT + ABM (vs. CBT plus attention training placebo; PBO) on those outcomes. METHOD: This study is a secondary analysis (Baker et al., 2020). Adults with PD were randomized to receive CBT + ABM (n = 11) or CBT + PBO (n = 12). Before each of the first five CBT sessions, CBT + ABM and CBT + PBO participants completed a 15-min ABM task or attention training PBO, respectively. AS and depression severity as well as SC and EMG during habituation to a loud-tone startle paradigm were assessed. Hierarchical Bayesian analyses were conducted. RESULTS: During pre-post-treatment and pre-follow-up, CBM + ABM (vs. CBT + PBO) led to a notably greater reduction in ASI-Physical (between-group d = -1.26 to -1.25), ASI-Cognitive (d = -1.16 to -1.10), and depression severity (d = -1.23 to -0.99). However, no between-group difference was observed for ASI-Social, EMG, or SC indices. DISCUSSION: Adding a brief computerized ABM intervention to CBT for PD protocols may enhance therapeutic change.

ABSTRACT

BACKGROUND: Depressive and obsessive-compulsive (OCD) symptoms often co-occur and a number of possible explanations for this co-occurrence have been explored, including shared biological and psychosocial risk factors. Network approaches have offered a novel hypothesis for the link between depression and OCD: functional inter-relationships across the symptoms of these conditions. The few network studies in this area have relied largely on item, rather than process-level constructs, and have not examined relationships dimensionally. METHODS: Network analytic methods were applied to data from 463 treatment-seeking adults with OCD. Patients completed self-report measures of OCD and depression. Factor analysis was used to derive processes (i.e., nodes) to include in the network. Networks were computed, and centrality, bridge, and stability statistics examined. RESULTS: Networks showed positive relations among specific OCD and depressive symptoms. Obsessions (particularly repugnant thoughts), negative affectivity, and cognitive-somatic changes (e.g., difficulty concentrating) were central to the network. Unique relations were observed between symmetry OCD symptoms and cognitive-somatic changes. No direct link between harm-related OCD symptoms and depression was observed. CONCLUSIONS: Our results bring together prior findings, suggesting that both negative affective and psychomotor changes are important to consider in examining the relationship between OCD and depression. Increased consideration of heterogeneity in the content of OCD symptoms is key to improving clinical conceptualizations, particularly when considering the co-occurrence of OCD with other disorders.

ABSTRACT

The novel coronavirus disease (COVID-19), first detected in December of 2019 and declared a global pandemic in March of 2020, continues to pose a serious threat to public health and safety worldwide. Many individuals report anxiety in response to this threat, and at high levels, such anxiety can result in adverse mental health outcomes and maladaptive behavioral responses that have consequences for the health of communities more broadly. Predictors of excessive anxiety in response to COVID-19 are understudied. Accordingly, the present study examined psychological factors that predict more intense COVID-19-related anxiety. 438 community members completed measures assessing COVID-19-related anxiety as well as psychological variables hypothesized to predict anxious responding to the threat of COVID-19. As expected, obsessive-compulsive symptoms related to contamination, the fear of arousal-related body sensations (i.e., anxiety sensitivity), and body vigilance each predicted more severe anxiety related to the pandemic. Obsessive-compulsive symptoms related to responsibility for causing harm also emerged as a predictor. Study limitations and implications are discussed.

ABSTRACT

Exposure and response prevention (ERP) is an effective treatment for obsessive compulsive disorder (OCD); yet, improvement rates vary and it is therefore important to examine potential predictors of outcome. The present study examined adherence with ERP homework as a predictor of (a) treatment response across OCD symptom dimensions and (b) reductions in psychological factors implicated in the maintenance of OCD. Fifty adults with OCD received manualized twice-weekly ERP as part of a treatment trial. Results indicated that treatment was effective for all OCD symptom dimensions and that greater adherence with ERP homework predicted post-treatment (but not follow-up) improvements in OCD symptoms pertaining to responsibility for harm, unacceptable obsessional thoughts, and symmetry. Adherence did not predict outcomes for contamination symptoms, however. Adherence also predicted improvement in psychological maintenance factors such as obsessive beliefs and experiential avoidance. Implications of the findings include the importance of emphasizing adherence to homework instructions, as well as the importance of considering OCD symptoms dimensionally as opposed to globally in examining predictors of treatment response.

ABSTRACT

Pituitary adenylate cyclase activating polypeptide (PACAP, gene Adcyap1) is a neuropeptide and hormone thought to play a critical role in stress response (Stroth et al., Ann NY Acad Sci 1220:49-59, 2011; Hashimoto et al., Curr Pharm Des 17:985-989, 2011). Research in humans implicates PACAP as a useful biomarker for the severity of psychiatric symptoms in response to psychological stressors, and work in rodent models suggests that PACAP manipulation exerts downstream effects on peripheral hormones and behaviors linked to the stress response, providing a potential therapeutic target. Prior work has also suggested a potential sex difference in PACAP effects due to differential estrogen regulation of this pathway. Therefore, we examined serum PACAP and associated PAC1R genotype in a cohort of males and females with a primary diagnosis of generalized anxiety disorder (GAD) and nonpsychiatric controls. We found that, while circulating hormone levels were not associated with a GAD diagnosis overall (p = 0.19, g = 0.25), PACAP may be associated with GAD in females (p = 0.04, g = 0.33). Additionally, among patients with GAD, the risk genotype identified in the PTSD literature (rs2267735, CC genotype) was associated with higher somatic anxiety symptom severity in females but lower somatic anxiety symptom severity in males (-3.27, 95%CI [-5.76, -0.77], adjusted p = 0.03). Taken together, the associations between the risk genotype, circulating PACAP, and somatic anxiety severity were stronger among females than males. These results indicate a potential underlying biological etiology for sex differences in stress-related anxiety disorders that warrants further study.

ABSTRACT

BACKGROUND: Complicated grief (CG) is a bereavement-specific syndrome distinct from but commonly comorbid with posttraumatic stress disorder (PTSD). While bereavement is common among military personnel (Simon et al., 2018), there is little research on the impact of CG comorbidity on PTSD treatment outcomes. METHODS: To evaluate the impact of comorbid CG on PTSD treatment outcomes we analyzed data from a randomized trial comparing prolonged exposure, sertraline, and their combination in veterans with a primary diagnosis of combat-related PTSD (n = 194). Assessment of PTSD, trauma-related guilt, functional impairment, and suicidal ideation and behavior occurred at baseline and weeks 6, 12, and 24 during the 24-week trial. RESULTS: CG was associated with lower PTSD treatment response (odds ratio (OR) = 0.29, 95% confidence interval (CI) [0.12, 0.69], p = 0.005) and remission (OR = 0.28, 95% CI [0.11, 0.71], p = 0.007). Those with CG had greater severity of PTSD (p = 0.005) and trauma-related guilt (<0.001) at baseline and endpoint. In addition, those with CG were more likely to experience suicidal ideation during the study (CG: 35%, 14/40 vs. no CG 15%, 20/130; OR = 3.01, 95% CI [1.29, 7.02], p = 0.011). CONCLUSIONS: Comorbid CG is associated with elevated PTSD severity and independently associated with poorer endpoint treatment outcomes in veterans with combat-related PTSD, suggesting that screening and additional intervention for CG may be needed.

ABSTRACT

Cognitive fusion (CF) involves the tendency to "buy in" to thoughts and feelings and consists of three empirically established domains: somatic concerns, emotion regulation, and negative evaluation. CF is hypothesized to play a role in obsessive-compulsive disorder (OCD). The present study examined how well the CF domains, relative to traditional cognitive-behavioural constructs (i.e., obsessive beliefs such as inflated responsibility), predict OCD symptoms. Fifty-two treatment-seeking adults with OCD completed self-report measures of CF, obsessive beliefs, OCD symptoms, and general distress. Domains of CF were differentially associated with the responsibility for harm, symmetry, and unacceptable thoughts of OCD dimensions; yet after accounting for obsessive beliefs, only the negative evaluation domain of CF significantly predicted symmetry OCD symptoms. Obsessive beliefs significantly predicted all OCD dimensions except for contamination. These findings provide additional support for existing cognitive-behavioural models of OCD across symptom dimensions, with the exception of contamination symptoms, and suggest that the believability of thoughts and feelings about negative evaluation adds to the explanation of symmetry symptoms. Conceptual and treatment implications, study limitations, and future directions are discussed.

ABSTRACT

Complicated grief (CG) is a debilitating syndrome characterized by persisting and intense distress and impairment after the death of a loved one. The biological mechanisms associated with this syndrome remain unclear but may involve neurobiological pathways implicated in the stress response and attachment systems. The neuropeptide oxytocin has been implicated in attachment and social behaviour, and loss of social bonds has been associated with disruptions in oxytocin signalling. Furthermore, prior research has reported associations between circulating oxytocin and other mental illnesses, including depression. The present pilot study aimed to examine plasma levels of oxytocin in bereaved adults with primary CG (n = 47) compared to age- and sex-matched bereaved individuals with primary Major Depressive Disorder (MDD) (n = 46), and bereaved individuals without any mental disorder (n = 46). In unadjusted analyses comparing groups according to primary diagnosis, oxytocin levels were significantly higher for primary CG compared to primary MDD (p = 0.013), but not compared to bereaved controls (p = 0.069). In adjusted regression models, having a primary or probable (Inventory of Complicated Grief ≥ 30) diagnosis of CG was associated with significantly higher oxytocin levels (p = 0.001). While additional research is needed, findings from our pilot study provide preliminary support for recent conceptualizations of CG implicating a role for oxytocin and the attachment system. Importantly, these findings contribute to the limited current knowledge about possible biological correlates of CG.


El duelo complicado (DC) es un síndrome debilitante caracterizado por intenso y persistente malestar y discapacidad, luego de la muerte de un ser querido. Los mecanismos biológicos asociados con este síndrome no están claros, pero pueden involucrar vías neurobiológicas implicadas en la respuesta al estrés y sistemas de apego. El neuropéptido oxitocina ha sido implicado en el apego y el comportamiento social, y la pérdida de vínculos sociales ha sido asociada a disrupciones en la señal de oxitocina. Más aún, la investigación previa ha reportado asociaciones entre la oxitocina circulante y otras enfermedades mentales, incluyendo depresión. El presente estudio piloto apuntó a examinar los niveles plasmáticos de oxitocina en adultos en duelo con DC primario (n = 47), comparados con personas con Trastorno Depresivo Mayor (TDM) primario emparejados por edad y sexo (n = 46), y con personas en duelo sin ningún trastorno mental (n = 46). En los análisis sin ajustar que compararon grupos de acuerdo al diagnóstico primario, los niveles de oxitocina fueron significativamente mayores para el DG primario, en comparación a TDM primario (p = 0.013), pero no en la comparación con controles en duelo (p = 0.069). En los modelos de regresión ajustados, el tener un diagnóstico primario o probable de DC (Inventario de Duelo Complicado ≥ 30) fue asociado a niveles significativamente mayores de oxitocina (p = 0.001). A pesar de que se requiere mayor investigación, los hallazgos de nuestro estudio piloto proveen soporte preliminar a las recientes conceptualizaciones del DC que implican un rol de la oxitocina y el sistema de apego. Importantemente, estos hallazgos contribuyen al limitado conocimiento actual acerca de los posibles correlatos biológicos del DC.

ABSTRACT

Gambling disorder is an impairing condition confounded by psychiatric co-morbidity, particularly with substance use and anxiety disorders. Yet, our knowledge of the mechanisms that cause these disorders to coalesce remains limited. The Incentive Sensitization Theory suggests that sensitization of neural "wanting" pathways, which attribute incentive salience to rewards and their cues, is responsible for the excessive desire for drugs and cue-triggered craving. The resulting hyper-reactivity of the "wanting' system is believed to heavily influence compulsive drug use and relapse. Notably, evidence for sensitization of the mesolimbic dopamine pathway has been seen across gambling and substance use, as well as anxiety and stress-related pathology, with stress playing a major role in relapse. Together, this evidence highlights a phenomenon known as cross-sensitization, whereby sensitization to stress, drugs, or gambling behaviors enhance the sensitivity and dopaminergic response to any of those stimuli. Here, we review the literature on how cue attraction and reward uncertainty may underlie gambling pathology, and examine how this framework may advance our understanding of co-mordidity with substance-use disorders (e.g., alcohol, nicotine) and anxiety disorders. We argue that reward uncertainty, as seen in slot machines and games of chance, increases dopaminergic activity in the mesolimbic pathway and enhances the incentive value of reward cues. We propose that incentive sensitization by reward uncertainty may interact with and predispose individuals to drug abuse and stress, creating a mechanism through which co-mordidity of these disorders may emerge.

ABSTRACT

Objective: To conduct a pilot test of the validity of using empirically derived personality types to characterize eating disorder (ED) risk in college students and resolve discrepancies regarding the role of perfectionism and obsessive-compulsive disorder (OCD) symptoms.Participants: Man and woman undergraduate students (N = 169) at a small, private university. Data were collected from February to May 2016 and 2018. Methods: Participants completed self-report measures of personality (perfectionism, impulsivity, and effortful control) and psychopathology (EDs, OCD). Results: Our analyses replicated three validated personality types: overcontrolled, undercontrolled, and resilient. Analysis of variances demonstrated perfectionism, ED, and OCD symptoms were significantly elevated in the overcontrolled subtype. There was no interaction by sex. Conclusions: These findings suggest that personality types may be useful for classifying ED risk and OCD symptoms in college students across sexes. Further study and relevance to prevention and intervention efforts to reduce the burden of EDs on college campuses will be discussed.

ABSTRACT

LEARNING OBJECTIVES: After participating in this activity, learners should be better able to:• Evaluate psychotherapeutic and pharmacologic approaches to treating patients with posttraumatic stress disorder. ABSTRACT: A strong evidence base exists for psychological and pharmacological interventions for the treatment of posttraumatic stress disorder (PTSD). The published literature investigating the effectiveness of these treatments in reducing the symptoms and impairments associated with PTSD has expanded substantially in recent years. This review provides a concise overview of the empirical literature examining these treatment approaches. Evidence-based, trauma-focused therapies are recommended as first-line interventions, with the most support for cognitive- and exposure-based approaches. Prolonged exposure and cognitive processing therapy are the two most cited and rigorously investigated. Various other evidence-supported protocols are discussed. Pharmacotherapies can be used when evidence-based psychotherapies are not available or are ineffective, or on the basis of patient preference. Pharmacotherapy with the most support for PTSD includes selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors. Evidence supports the implementation of these interventions across genders, populations, and settings. Given that little research directly compares the effectiveness of different PTSD interventions and their mechanisms of action, it remains uncertain how to best select and tailor treatments to optimize individual outcomes. Future directions and novel, ongoing research are discussed.

ABSTRACT

Gambling disorder (GD) frequently co-occurs with alcohol use and anxiety disorders, suggesting possible shared mechanisms. Recent research suggests reward uncertainty may powerfully enhance attraction towards reward cues. Here, we examined the effects of adolescent ethanol exposure, anxiety, and reward uncertainty on cue-triggered motivation. Male and female adolescent rats were given free access to ethanol or control jello for 20days. Following withdrawal, rats underwent autoshaping on a certain (100%-1) or uncertain (50%-1-2-3) reward contingency, followed by single-session conditioned reinforcement and progressive ratio tasks, and 7days of omission training, during which lever pressing resulted in omission of reward. Finally, anxiety levels were quantified on the elevated plus maze. Here, we found that uncertainty narrowed cue attraction by significantly increasing the ratio of sign-tracking to goal-tracking, particularly amongst control jello and high anxiety animals, but not in animals exposed to ethanol during adolescence. In addition, attentional bias towards the lever cue was more persistent under uncertain conditions following omission training. We also found that females consumed more ethanol, and that uncertainty mitigated the anxiolytic effects of ethanol exposure observed in high ethanol intake animals under certainty conditions. Our results further support that reward uncertainty biases attraction towards reward cues, suggesting also that heightened anxiety may enhance vulnerability to the effects of reward uncertainty. Chronic, elevated alcohol consumption may contribute to heightened anxiety levels, while high anxiety may promote the over-attribution of incentive value to reward cues, highlighting possible mechanisms that may drive concurrent anxiety, heavy drinking, and problematic gambling.

ABSTRACT

Bereavement is a potent and highly prevalent stressor among service members and veterans. However, the psychological consequences of bereavement, including complicated grief (CG), have been minimally examined. Loss was assessed in 204 post-9/11, when service members and veterans with combat-related posttraumatic stress disorder (PTSD) took part in a multicenter treatment study. Those who reported the loss of an important person completed the inventory of complicated grief (ICG; n = 160). Over three quarters (79.41%) of the sample reported an important lifetime loss, with close to half (47.06%) reporting the loss of a fellow service member (FSM). The prevalence of CG was 24.75% overall, and nearly one third (31.25%) among the bereaved. CG was more prevalent among veterans who lost a fellow service member (FSM) (41.05%, n = 39) compared to those bereaved who did not (16.92%, n = 11; OR = 3.41, 95% CI: 1.59, 7.36). CG was associated with significantly greater PTSD severity, functional impairment, trauma-related guilt, and lifetime suicide attempts. Complicated grief was prevalent and associated with adverse psychosocial outcomes in veterans and service members with combat-related PTSD. Clinicians working with this population should inquire about bereavement, including loss of a FSM, and screen for CG. Additional research examining CG in this population is needed.
