Preventative and restorative safety behaviors: Effects on exposure treatment outcomes and risk for future anxious symptoms

Reducing safety behaviors to prevent anxious symptoms: a pre-registered prevention intervention study

The purpose of this pre-registered study was to test the efficacy of a simple, low-impact safety behavior prevention intervention for anxiety. The intervention was delivered online using a 4-week workbook format. Participants (n = 130) were a non-clinical sample of American college students; they were randomly assigned to one of two intervention conditions: safety-behavior reduction or active control condition (academic skills). Results showed that participants in the safety behavior workbook condition did not report fewer safety behaviors or lower levels of anxiety compared to the active control condition post-intervention. Exploratory analyses found that fidelity mattered; participants who completed all the workbook activities reported a significant decrease in the safety-behaviors relative to the control condition. However, those who reduced their use of safety behaviors reported greater levels of anxiety compared to participants in the control condition who reduced their safety behaviors. These results suggest that encouraging safety behavior reduction in non-clinical samples may have the unintended consequence of maintaining anxiety.

Changes in cognitive processes and coping strategies precede changes in symptoms during cognitive therapy for posttraumatic stress disorder

Theories of posttraumatic stress disorder (PTSD) highlight the role of cognitive and behavioral factors in its development, maintenance, and treatment. This study investigated the relationship between changes in factors specified in Ehlers and Clark's (2000) model of PTSD and PTSD symptom change in 217 patients with PTSD who were treated with cognitive therapy for PTSD (CT-PTSD) in routine clinical care. Bivariate latent change score models (LCSM) of session-by-session changes in self-report measures showed that changes in PTSD symptoms were preceded by changes in negative appraisals, flashback characteristics of unwanted memories, safety behaviours, and unhelpful responses to intrusions, but not vice versa. For changes in trauma memory disorganization and PTSD symptoms we found a bidirectional association. This study provides evidence that cognitive and behavioral processes proposed in theoretical models of PTSD play a key role in driving symptom improvement during CT-PTSD.

Learning About Safety: Conditioned Inhibition as a Novel Approach to Fear Reduction Targeting the Developing Brain

Adolescence is a peak time for the onset of psychiatric disorders, with anxiety disorders being the most common and affecting as many as 30% of youths. A core feature of anxiety disorders is difficulty regulating fear, with evidence suggesting deficits in extinction learning and corresponding alterations in frontolimbic circuitry. Despite marked changes in this neural circuitry and extinction learning throughout development, interventions for anxious youths are largely based on principles of extinction learning studied in adulthood. Safety signal learning, based on conditioned inhibition of fear in the presence of a cue that indicates safety, has been shown to effectively reduce anxiety-like behavior in animal models and attenuate fear responses in healthy adults. Cross-species evidence suggests that safety signal learning involves connections between the ventral hippocampus and the prelimbic cortex in rodents or the dorsal anterior cingulate cortex in humans. Particularly because this pathway follows a different developmental trajectory than fronto-amygdala circuitry involved in traditional extinction learning, safety cues may provide a novel approach to reducing fear in youths. In this review, the authors leverage a translational framework to bring together findings from studies in animal models and humans and to bridge the gap between research on basic neuroscience and clinical treatment. The authors consider the potential application of safety signal learning for optimizing interventions for anxious youths by targeting the biological state of the developing brain. Based on the existing cross-species literature on safety signal learning, they propose that the judicious use of safety cues may be an effective and neurodevelopmentally optimized approach to enhancing treatment outcomes for youths with anxiety disorders.

Teasing Apart the Effect of Depression Specific and Anxiety Specific Symptoms on Academic Outcomes

Research shows that adolescents' performance in school can be negatively affected by depression and anxiety. However, past studies have used nonspecific measures of depression and anxiety that preclude researchers from understanding their unique effects. The current study addressed this gap in the literature by teasing apart the effects of depression specific and anxiety specific symptoms on end of semester grade point average (GPA) and the likelihood of dropping a course. We used a 3-month longitudinal design with a sample of 130 United States (U.S.) undergraduates. Results showed that only cumulative GPA and ACT score predicted end of semester GPA. However, high levels of anxiety specific (anxious arousal), but not depression specific (anhedonia), symptoms predicted whether or not a student dropped a course. These results suggest that targeting anxiety specific symptoms in schools may be effective in improving academic outcomes.
