Temperament Based Therapy with Support (TBT-S) is an emerging neurobiologically informed treatment approach designed to augment existing treatments. This book describes how and why TBT-S has been developed for adults with anorexia nervosa (AN), recognizing it has the capacity to be applied to other psychological disorders. TBT-S fills the gap between research and clinical practice by acknowledging and treating underlying brain-based factors. TBT-S recognizes that there is a biological basis to psychological illnesses that involves temperament and altered brain function. It is developed as a modular treatment virtually or face-to-face. The “S” of TBT-S means “Support,” the word chosen by adults clients with AN to describe anyone who offers support. Clinicians can insert TBT-S modules into ongoing therapies ranging from one module in an outpatient treatment settings to a day of TBT-S to the 5-day,40-hour, 1e-week TBT-S program that was studied.
TBT-S utilizes multiple intervention strategies to apply TBT-S principles. These strategies have been developed and adapted over a 10-year period through iteratively integrating client and Support feedback with research findings in the treatment development process to increase accuracy and acceptability. The interventions are (1) neurobiological psychoeducation, (2)experiential learning addressing AN neurobiology and traits for problem-solving activities for clients and Supports, (4) client and Support skills training, (5) meal coaching, and (6) The TBT-S Behavioral Agreement.
Body dysmorphic disorder (BDD) is a debilitating disorder, characterized by obsessions and compulsions relating specifically to perceived appearance, and which has been newly classified within the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Obsessive-Compulsive and Related Disorders grouping. Until now, little research has been conducted into the cognitive profile of this disorder.
Methods
Participants with BDD (n=12) and participants without BDD (n=16) were tested using a computerized neurocognitive battery investigating attentional set-shifting (Intra/Extra Dimensional Set Shift Task), decision-making (Cambridge Gamble Task), motor response-inhibition (Stop-Signal Reaction Time Task), and affective processing (Affective Go-No Go Task). The groups were matched for age, IQ, and education.
Results
In comparison to controls, patients with BDD showed significantly impaired attentional set-shifting, abnormal decision-making, impaired response inhibition, and greater omission and commission errors on the emotional processing task.
Conclusion
Despite the modest sample size, our results showed that individuals with BDD performed poorly compared to healthy controls on tests of cognitive flexibility, reward and motor impulsivity, and affective processing. Results from separate studies in OCD patients suggest similar cognitive dysfunction. Therefore, these findings are consistent with the reclassification of BDD alongside OCD. These data also hint at additional areas of decision-making abnormalities that might contribute specifically to the psychopathology of BDD.
