Exploring the Effects of the Mindfulness and Countering Emotional Behaviors Modules From the Unified Protocol on Dysregulated Anger in the Context of Emotional Disorders

Within-person changes in aversive reactivity predict session-to-session reductions in anxiety and depression in the unified protocol

ABSTRACTThe Unified Protocol (UP) theoretically leads to reductions in emotional disorder symptoms by reducing aversive reactions to emotions. However, aversive reactions can take many forms (e.g., non-acceptance, behavioral avoidance). We examined if (1) multiple aspects of aversive reactivity predicted session-to-session changes in anxiety and depression in the UP, (2) these aspects reflected a single latent construct, and (3) changes in this latent construct predicted changes in anxiety and depression. Participants (N = 70, Mage = 33.74, 67.1% female, 74.3% white) completed six sessions of UP modules and measures of aversive reactivity, anxiety, and depression before each session. We used hierarchical linear modeling and random-intercept cross-lagged panel models to test aspects of aversive reactivity and a latent factor of aversive reactivity, respectively, as predictors of session-to-session changes in anxiety and depression. Within-person improvements in four of five aspects of aversive reactivity predicted decreases in anxiety, and improvements in two aspects predicted decreases in depression. However, within-person improvements in latent aversive reactivity predicted decreases in anxiety at five sessions and in depression across all sessions. These results add to the growing literature highlighting the role of aversive reactivity as a potential transdiagnostic process involved in improvements in emotional disorder symptoms during treatment.

A practitioner's guide to conducting and analysing embedded randomized single-case experimental designs

Single-case experimental designs (SCEDs) are a class of experimental designs suited for answering research questions at an individual level. The main designs available in SCED research are phase designs, multiple baseline designs, alternation designs, and changing criterion designs. Embedded designs, also referred to as combination or hybrid designs, consist of one of these basic designs forms embedded in another design (e.g., a changing criterion design embedded in a multiple baseline design). Systematic reviews of SCEDs have repeatedly indicated that embedded designs are frequently used in applied SCED research. In spite of their popularity, specific recommendations on the conduct and analysis of embedded SCED designs are lacking to date. The purpose of the present article is therefore to provide guidance to applied researchers wishing to conduct embedded SCED designs in terms of design options, design requirements, randomization, and data analysis.

Trait anger expression mediates childhood trauma predicting for adulthood anxiety, depressive, and alcohol use disorders

BACKGROUND

General aggression and evolutionary models posit that more severe early exposure experiences to trauma (physical, emotional, sexual abuse and/or neglect) place one at risk for adulthood psychopathology through heightened trait anger expression-internal (Anger-In) and external (Anger-Out). However, there are a dearth of empirical studies explaining the longitudinal childhood maltreatment-adulthood psychopathology relation.

OBJECTIVE

Therefore, this study investigated if childhood maltreatment exposure severity predicted elevated adulthood major depressive disorder (MDD), generalized anxiety disorder (GAD), panic disorder (PD), and alcohol use disorder (AUD). Moreover, we tested if trait anger expression - internal and external - mediated the childhood maltreatment-adulthood MDD, GAD, PD, and AUD symptom associations.

METHOD

Participants took part in two waves of measurement spaced approximately 9 years apart. Time 1 childhood trauma severity (retrospectively-reported Childhood Trauma Questionnaire), Time 2 Anger-In and Anger-Out (State-Trait Anger Expression Inventory), and Time 3 adulthood MDD, GAD, PD (Composite International Diagnostic Interview-Short Form), and AUD (Alcohol Screening Test) diagnoses were measured.

RESULTS

Anger-Out and Anger-In partially mediated the relations between childhood trauma severity and adulthood psychopathology diagnoses after adjusting for Time 2 symptoms. Higher Time 1 childhood trauma severity was related to greater Time 2 Anger-Out and Anger-In, and increased Time 2 Anger-Out and Anger-In were thereby related to elevated Time 3 adulthood MDD, PD and AUD, but not GAD severity. Trait anger accounted for 14 to 50% of the variance of childhood trauma-adulthood MDD, PD and AUD relations.

DISCUSSION

Theoretical and clinical implications, such as the need for trauma-informed care, are discussed.

The moderating effects of anger suppression and anger expression on cognitive behavioral group therapy and mindfulness-based stress reduction among individuals with social anxiety disorder

BACKGROUND

. Cognitive-behavioral therapy and mindfulness-based stress reduction (MBSR) are two prominent evidence-based treatments for social anxiety disorder (SAD). It is not clear, however, whether outcomes of these two treatments are moderated by similar factors. For example, whereas anger suppression and anger expression each predict outcomes in cognitive- behavioral group therapy (CBGT), it is unknown whether they differentially influence outcomes in CBGT versus MBSR.

METHODS

. One hundred eight participants with SAD were randomized to CBGT, MBSR or Waitlist (WL). WL participants were later randomized to CBGT or MBSR, and their data were combined with data from those originally randomized to CBGT or MBSR. Anger suppression and anger expression were assessed at pre-treatment, and social anxiety was assessed at pre-treatment, post-treatment, and every 3 months throughout a 12-month follow-up period.

RESULTS

. From pre- to post-treatment, higher anger suppression was associated with significantly greater reduction in social anxiety in CBGT compared with MBSR. From post-treatment through follow-up, higher anger expression was associated lesser reduction in social anxiety in MBSR but not in CBGT.

LIMITATIONS

. Data are limited by sole reliance on self-report and it is unclear whether these findings generalize beyond group-based interventions.

CONCLUSIONS

. Individuals with SAD who are higher in anger suppression and/or expression might be better suited to CBGT than MBSR.
