Patient experiences with group behavioural activation in a partial hospital program.

BACKGROUND: Behavioural activation (BA) is an evidence-based treatment for depression that has been primarily delivered in individual out-patient treatment. Prior research supports a positive participant experience in individual therapy; however, less is known about the patient experience in group therapy, which is common in acute psychiatric settings. AIMS: The present study examined the patient experience of Brief Behavioral Activation Treatment for Depression (BATD) delivered in group acute psychiatric treatment. METHOD: We used thematic analysis to extract themes from feedback surveys administered as part of quality improvement practice at a partial hospital program. Survey questions explored what patients learned, liked, disliked and thought could be improved in the BATD groups. Three individuals independently coded survey responses and collaboratively developed categories and themes. RESULTS: Themes included several helpful content areas (e.g. value-driven activities, increasing motivation, goal setting, activity scheduling, cognitive behavioural model, self-monitoring) and learning methods (e.g. group format, experiential exercises, worksheets). Patients also identified unhelpful content (e.g. specific focus on depression and listing activities by mood). There was mixed feedback regarding the repetition of material and balance of lecture versus group participation. CONCLUSION: Overall, these findings suggest a mostly positive patient experience of group-delivered BATD and support the acceptability of group-delivered BATD as a component of short-term intensive treatment.

Decreased Amygdalar Activation to NSSI-Stimuli in People Who Engage in NSSI: A Neuroimaging Pilot Study.

In healthy individuals, stimuli associated with injury (such as those depicting blood or wounds) tend to evoke negative responses on both self-report and psychophysiological measures. Such an instinctive aversion makes sense from an evolutionary perspective. However, to engage in nonsuicidal self-injury (NSSI), this natural barrier must be overcome. The Benefits and Barriers model of NSSI predicts that people who engage in NSSI will show diminished aversion to NSSI-related stimuli compared to controls who do not engage in NSSI. We tested this hypothesis in a pilot study assessing 30 adults, 15 of whom reported current skin cutting and 15 of whom had no history of NSSI. Functional magnetic resonance imaging (fMRI) data were collected while participants viewed neutral, positive, and negative images selected from the International Affective Picture System. Participants also viewed NSSI images depicting razors, scalpels, or wounds caused by cutting. Compared to healthy control (HC) participants, the NSSI group showed decreased amygdala and increased cingulate cortex (CC) and orbitofrontal cortex (OFC) activation to NSSI and negative images. They also showed increased amygdalar and OFC activation to positive images. Neither the control group nor the NSSI group demonstrated significant activation within regions more typically associated with reward during any of the conditions; however, positive and negative affect ratings collected throughout the course of the task suggested that none of the affective conditions were viewed as rewarding. Although preliminary, these findings are suggestive of reduced limbic and greater cortical processing of NSSI stimuli in those with a history of this behavior. This has potentially important implications for current models of NSSI as well as for its treatment.

Prefrontal cortex activation during cognitive interference in nonsuicidal self-injury.

Nonsuicidal self-injury (NSSI), deliberate behavior resulting in self-inflicted damage to oneself, is common, particularly among female adolescents, and may be a form of maladaptive emotion regulation. Cognitive interference, a specific type of processing associated with inhibiting prepotent responses in favor of less automatic ones, is utilized in treatment strategies to shift patients' thoughts and behaviors away from maladaptive responses and replace them with more adaptive ones. We examined cognitive interference processing using the Multi-Source Interference Task (MSIT) in females with NSSI behavior (n=15) and healthy control females (n=15). Functional magnetic resonance imaging (fMRI) data were collected concurrently. Results revealed similar between-group performance on the MSIT; however, women with NSSI behavior exhibited altered patterns of neural activation during the MSIT. Specifically, the NSSI group demonstrated increased cingulate cortex (CC) and decreased dorsolateral prefrontal cortex (DLPFC) activation compared to the control group. Further, within the NSSI group, DLPFC activation inversely correlated with emotional reactivity and self-reported impulsivity, suggesting that decreased DLPFC activation is associated with poorer emotional control and increased impulsivity. Taken together, these results indicate that women with NSSI behavior utilize different cortical areas during cognitive interference processing, which may have broader implications regarding the treatment efficacy of cognitive-based therapies.
