Effectiveness of a Behavioral Activation Intervention for Peripartum Women with Opioid Use Disorder.

Pregnant women with opioid use disorder show elevated rates of comorbid mental health problems, both of which are associated with negative health outcomes for mothers and children. There is substantial evidence supporting the benefits of treatment of perinatal opioid use disorder, as well as perinatal depression and anxiety, but there are gaps in knowledge about the effectiveness of perinatal behavioral health interventions in the context of co-occurring substance use disorder. The current study seeks to address this gap by examining outcomes of a behavioral activation treatment in a group of peripartum women with opioid use disorder (N = 68). Behavioral activation has shown promise in treating co-occurring depression and substance use problems. The intervention was delivered as part of an integrated care treatment model, in which patients received co-located obstetric, substance use, and mental health care in a hospital-based clinic. Hierarchical linear modeling was used to assess change in symptoms over time. Results suggest that the group behavioral activation intervention was associated with reduced depression and anxiety symptoms, demonstrated by significant reductions in PHQ-9 and GAD-7 scores over the course of treatment. Moreover, there were indications that increased attendance was associated with further reductions in depressive symptoms. Results contribute to understanding the effectiveness of behavioral activation in the context of peripartum opioid use disorder. Findings also add to the evidence supporting integrated care models and offer a potential blueprint for improving outcomes and reducing barriers to care in this population.

Approach behavior can mitigate predominately univalent negative attitudes: evidence regarding insects and spiders.

Three experiments tested whether disliking of predominately univalently negative attitude objects could be reduced by a procedure pairing approach behaviors with subliminally presented images of the objects. Experiment 1 demonstrated that participants who approached images of insects rated insects less negatively than participants who did not approach insect pictures. Experiment 2 extended this effect to spiders and used an implicit measure of spider attitudes. Experiment 3 examined the consequences of an approach induction for affect during actual approach behavior in a sample of individuals with elevated levels of spider fear by using a Behavioral Approach Task. Fearful individuals who approached spider pictures reported less anxiety when encountering live spiders than participants who did not approach spider pictures. As such, the results provided evidence on explicit, implicit, and behavioral measures that negative and predominately univalent attitudes can be influenced by approach behaviors. Implications for attitude change interventions and potential contribution to the efficacy of exposure therapy are discussed.

It was as big as my head, I swear! Biased spider size estimation in spider phobia.

The current study tested the association between fear and perception in spider phobic individuals (n=57) within the context of a treatment outcome study. Participants completed 5 post-treatment Behavioral Approach Tasks (BATs) in which they encountered a live spider and were asked to provide spider size estimates. Consistent with predictions, results indicated that high levels of fear were associated with magnified perception of phobic stimuli. Specifically, we found a significant positive correlation between size estimates and self-reported fear while encountering spiders. Together with previous findings, these results further support the notion that fear is involved in the encoding and processing of perceptual information.
