Targeting avoidance via compound extinction

ABSTRACT

Avoidance towards innocuous cues is a key diagnostic criterion across anxiety-related disorders. Importantly, the most effective intervention for anxiety-related disorders, exposure therapy with response prevention, sometimes does not prevent the relapse of anxiety's symptomatology. We tested whether extinction effects, the experimental proxy of exposure, are enhanced by increasing the discrepancy between the prediction of an unpleasant event happening (shock presentation), and the actual event (shock omission). Forty-eight individuals first saw pictures of three stimuli. Two pictures (CSA, CSB) were followed by a shock (US) and one (CS-) was not. Next, participants learned to avoid the US by pressing a computer key. An extinction and response prevention procedure followed. In the first part of it, participants saw unreinforced presentations of all CSs. In the second part, the single group saw unreinforced presentations of the CSA and CS-. The compound group encountered compound unreinforced presentations of the CSA and CSB, and separate presentations of the CS-. Return of avoidance and fear was tested after unsignalled presentations of the US. Compound extinction resulted in comparable reduction of fear and avoidance compared to standard extinction. We discuss how future research could enhance extinction effects by adding costs to the avoidance behaviour.     

Body and meaning

Abstract

This paper discusses the very important but disregarded theme of somatization. Somatizers comprise a wide-ranging group of patients, who normally choose to consult doctors rather than psychoanalysts for treatment. We present two clinical reports of somatizing patients in which the psychoanalyst played a considerable role in the study and treatment of their problems. The subjects were not only totally relieved of their physical symptoms, but also dramatically changed their psychic lives.     

Memory Functioning in Children with Reading Disabilities and/or Attention Deficit/Hyperactivity Disorder: A Clinical Investigation of their Working Memory and Long-Term Memory Functioning

We examined memory functioning in children with reading disabilities (RD), Attention deficit/hyperactivity disorder (ADHD), and RD/ADHD using a clinic sample with a clinical instrument: the Children's Memory Scale, enhancing its generalizability. Participants included 23 children with RD, 30 with ADHD, 30 with RD/ADHD, and 30 controls. Children with RD presented with reduced verbal short-term memory (STM) but intact visual STM, central executive (CE), and long-term memory (LTM) functioning. Their deficit in STM appeared specific to tasks requiring phonetic coding of material. Children with ADHD displayed intact CE and LTM functioning but reduced visual-spatial STM, especially when off stimulant medication. Children with RD/ADHD had deficits consistent with both disorders.     

Improving executive functioning in children with fetal alcohol spectrum disorders

An extensive body of literature has documented executive function (EF) impairments in children with fetal alcohol spectrum disorders (FASD); however, few studies have aimed specifically at improving EF. One treatment program that shows promise for children with FASD is the Alert Program for Self-Regulation®, which is a 12-week treatment specifically designed to target self-regulation, a component of EF. The present study sought to examine if Alert would produce improvements in self-regulation that would generalize to other aspects of EF, behavior, and social skills in children with FASD. Twenty-five children aged 8–12 years diagnosed with an FASD were assigned in alternating sequence to either an immediate treatment (TXT) or a delayed treatment control (DTC) group. Both groups received a comprehensive evaluation of EF at baseline and upon completing therapy (TXT), or after a 12- to 14-week interval from baseline (DTC). Parents also completed questionnaires assessing EF and behavior at both time points. For the TXT group only, parent questionnaires were readministered at 6-month follow-up. At the 12-week follow-up, the TXT group displayed significant improvements in inhibitory control and social cognition. Parents of children in the TXT group reported improved behavioral and emotional regulation, as well as reduced externalizing behavior problems. These behavioral improvements along with further improved parent-rated inhibitory control was maintained at the 6-month follow-up. The EF disabilities in children with FASD can be remediated through a targeted treatment approach aimed at facilitating self-regulation skills.     

The Therapeutic Process with Children with Learning Disorders

Abstract

Clinicians who work with children and adolescents with learning disorders must be aware of the relationship between the learning disorder and the psychopathology the children present. This article offers a conceptual framework, based on psychoanalytic self psychology, to understand the modifications that are necessary in the treatment of this population. The author suggests that, in contrast to other approaches, it is not possible to conceptualize the treatment of these children as having a beginning, a middle, and an end. Rather, the therapeutic process is open-ended and conceived as occurring during a series of moments. The moments may be categorized as concordant, complementary, or disjunctive. During concordant moments a holding environment is created; during complementary moments the transference and countertransference is addressed; and during disjunctive moments the ruptures that inevitably occur during treatment are dealt with.     

School-Linked Services in Context

Summary

This paper describes a formative evaluation of a school-linked service delivery system for immigrant and low income families in a large suburban county in Maryland. Initially we discuss local needs that prompted the development of the program and we place problems with services for children and families with multiple needs in a broad context. Next we discuss the methods and results of the evaluation. Findings indicate the program provides a range of appropriate services to intended beneficiaries but that lack of infrastructure and articulated understandings among participating organizations present potential problems.     

Deficits in perceived social support associated with generalized social phobia

Social phobia is a common anxiety disorder associated with significant impairment in social and occupational functioning. To date, few studies have examined the relationship between social phobia and perceived social support, a construct with important relationships to physical and mental health. The present study examined data from 2 widely used measures of perceived social support administered to 132 individuals with DSM‐IV generalized social phobia. These data were compared with those obtained from a healthy control group and from several clinical and non‐clinical samples reported in the literature. Persons with generalized social phobia scored significantly lower on both measures of social support compared with all other groups. It is suggested that deficits in perceived social support associated with generalized social phobia may play a role in the development of co‐morbid problems and should be explicitly targeted by treatments for social phobia. Low correlations between perceived social support and social anxiety measures suggest that perceived support should be specifically evaluated in this population.     

Homework Compliance Counts in Cognitive-Behavioral Therapy

Background: Prior research has demonstrated that there is some association between treatment engagement and treatment outcome in behavioral therapy for anxiety disorders. However, many of these investigations have been limited by weak measurement of treatment engagement variables, failure to control for potentially important baseline variables, and failure to consider various treatment engagement variables simultaneously. The purpose of the present study is to examine the relationship between two treatment engagement variables (treatment expectancy and homework compliance) and the extent to which they predict improvement from cognitive-behavioral therapy (CBT) for anxiety disorders. Methods: 84 adults with a DSM-IV-defined principal anxiety disorder took part in up to 12 sessions of CBT or acceptance and commitment therapy. Pre- and post-treatment disorder severity was assessed using clinical severity ratings from a semi-structured diagnostic interview. Participants made ratings of treatment expectancy after the first session. Homework compliance was assessed each session by the treating clinician. Results: Contrary to hypotheses, treatment expectancy and homework compliance were poorly correlated. Regression analyses revealed that homework compliance, but not treatment expectancy, predicted a significant portion of the variance in treatment outcome (10%). Conclusions: The present research suggests that although treatment expectation and homework compliance likely represent unique constructs of treatment engagement, homework compliance may be the more important treatment engagement variable for outcomes. The present research suggests that improvement of homework compliance has the potential to be a highly practical and effective way to improve clinical outcomes in CBT targeting anxiety disorders.
