Anxiety and selective attention in obsessive-compulsive disorder

Recently, there has been increasing evidence for information-processing deficits in individuals with obsessive-compulsive disorder (OCD). While impairments in selective attention have been identified to be central to the symptomatology of OCD, the role that situational anxiety plays in attentional processes has not been fully explored. Previous research findings were limited to tasks containing anxiety-relevant materials, only permitting for the evaluation of the impact of anxiety on simultaneous cognitive processing. Furthermore, it has not yet been determined whether the impact of anxiety is limited to selective attention or is indicative of a more general cognitive impairment. This study was designed to examine the role that situational anxiety plays in selective attention impairments. OCD participants and controls were presented with an anxiety producing statement and a neutral statement, followed by the Stroop Task. Results indicated that situational anxiety plays a significant role in the performance of tasks that require selective attention in OCD. A significant deterioration was detected in performance on selective attention tasks for the OCD participants after confronting anxiety-provoking scenarios, as compared to neutral scenarios. Anxiety did not impair performance on simple reading tasks. Possible explanations are discussed.     

Treatment of pharmacotherapy-refractory posttraumatic stress disorder among Cambodian refugees: a pilot study of combination treatment with cognitive-behavior therapy vs sertraline alone

Cambodian refugees with posttraumatic stress disorder (PTSD) represent a cohort in severe need of treatment, but little information is available to guide treatment choices. We selected a sample of pharmacotherapy-refractory individuals to test the efficacy of combination treatment with sertraline and cognitive-behavior therapy (CBT) for treating PTSD. Participants in this pilot study were ten Khmer-speaking women who had been at a mean age of 22-26 years during the Pol Pot period (1975-1979). These patients were randomly assigned to either sertraline alone or combined treatment. We found that combined treatment offered additional benefit in the range of medium to large effect sizes for PTSD and associated symptoms. Our findings indicate that substantial gains can be achieved by adding CBT to pharmacotherapy for PTSD, and that a program of CBT emphasizing information, exposure, and cognitive-restructuring can be successfully modified for Khmer-speaking refugees.     

The Meta-Cognitive Beliefs Questionnaire: development of a measure of obsessional beliefs

A 67 item self-report questionnaire called the Meta-Cognitive Beliefs Questionnaire (MCBQ) was developed to assess endorsement of beliefs about the importance of control and negative consequences associated with unwanted, ego-dystonic intrusive thoughts, images and impulses. The MCBQ and a battery of questionnaires that assessed symptoms and cognitions of worry, obsessive-compulsive disorder, anxiety, and depression were administered to large samples of undergraduate students. Beliefs about control of intrusive thoughts and perceived negative consequences due to uncontrolled mental intrusions had a unique significant relationship with obsessions, and to a lesser extent, worry. These findings are consistent with current cognitive behavioral theories that suggest an important role for meta-cognitive beliefs in the pathogenesis of obsessions.     

Anger-associated panic attacks in Cambodian refugees with PTSD; a multiple baseline examination of clinical data

Despite the increasing recognition of the importance of anger as a key aspect of post-traumatic stress disorder (PTSD), the presence of anger-induced panic attacks has been understudied in traumatized groups. The present investigation determines the prevalence of anger-associated panic attacks among Cambodian refugees suffering from PTSD. Specific characteristics of these episodes that were examined included frequency, symptoms, and cognitions (in particular, fear of death from bodily dysfunction). In a survey of 100 Khmer patients suffering PTSD, 58% reported anger-associated panic attacks in the last month. These attacks occurred at a mean rate of 6.2 attacks a month and were characterized by extreme arousal and in 81% of these cases, fears of death due to bodily dysfunction during the anger-induced panic. Mechanisms for this high rate of fear of death during anger arousal are discussed with a focus on culture-specific catastrophic cognitions.     

Sequential evaluation of behavioral treatments and methylphenidate dosage for children with attention deficit hyperactivity disorder

We used a sequential approach to evaluate the relative and combined effects of different types of behavioral treatments, as well as dosage of methylphenidate (MPH), on the disruptive behavior of 3 students who had been diagnosed with attention deficit hyperactivity disorder. Results showed that individualized behavioral treatments produced decreases in disruptive behavior equivalent to MPH for all 3 participants and demonstrated the need to evaluate behavioral treatments and medication dosage on an individual basis.     

Subfactors of DSM-IV Conduct Disorder: Evidence and Connections with Syndromes from the Child Behavior Checklist

Is conduct disorder (CD) as defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994) a unitary entity, or do variants of CD exist? We addressed this question, using data collected from the parents of 1,669 Australian boys, aged 6–17. Parents were interviewed to assess DSM-IV Conduct Disorder (DSM-IV CD) criteria. Results revealed 2 subfactors of DSM-IV CD symptoms, made up of overt behaviors (e.g., initiating physical fights) and covert behaviors (e.g., stealing without confrontation). Ordinary least squares regressions showed the 2 CD subfactors to be significantly and uniquely predicted by Child Behavior Checklist (CBCL; T. M. Achenbach, 1991a, 1991b) syndromes labeled Aggressive Behavior and Delinquent Behavior, respectively. The results are discussed in terms of the utility of differentiating these 2 variants of CD in future editions of the DSM.     

Listening comprehension and working memory are impaired in attention-deficit hyperactivity disorder irrespective of language impairment

This study investigated listening comprehension and working memory abilities in children with attention-deficit hyperactivity disorder (ADHD), presenting with and without language impairments (LI). A 4-group design classified a community sample (n = 77) of boys aged 9–12 into ADHD, ADHD + LI, LI, and Normal groups. Children completed tests of basic language and cognitive skills, verbal and spatial working memory, and passage-level listening comprehension. Multivariate analyses and post hoc comparisons indicated that ADHD children who did not have co-occurring LI comprehended factual information from spoken passages as well as normal children, but were poorer at comprehending inferences and monitoring comprehension of instructions. ADHD children did not differ from normal children in verbal span, but showed significantly poorer verbal working memory, spatial span, and spatial working memory. The ADHD + LI and LI groups were most impaired in listening comprehension and working memory performance, but did not differ from each other. Listening comprehension skills were significantly correlated with both verbal and spatial working memory, and parent–teacher ratings of inattention and hyperactivity/impulsivity. Findings that children with ADHD but no LI showed subtle higher-level listening comprehension deficits have implications for both current diagnostic practices and conceptualizations of ADHD.     

Demographic characteristics,social competence,and behavior problems in children with gender identity disorder: a cross-national,cross-clinic comparative analysis

This study examined demographic characteristics, social competence, and behavior problems in clinic-referred children with gender identity problems in Toronto, Canada (N = 358), and Utrecht, The Netherlands (N = 130). The Toronto sample was, on average, about a year younger than the Utrecht sample at referral, had a higher percentage of boys, had a higher mean IQ, and was less likely to be living with both parents. On the Child Behavior Checklist (CBCL), both groups showed, on average, clinical range scores in both social competence and behavior problems. A CBCL-derived measure of poor peer relations showed that boys in both clinics had worse ratings than did the girls. A multiple regression analysis showed that poor peer relations were the strongest predictor of behavior problems in both samples. This study—the first cross-national, cross-clinic comparative analysis of children with gender identity disorder—found far more similarities than differences in both social competence and behavior problems. The most salient demographic difference was age at referral. Cross-national differences in factors that might influence referral patterns are discussed.     

Treatment of Prostitution Using Integrative Therapy Techniques: A Case Study

This case study examines a pattern we believe to be common among female prostitutes: a woman (Bonnie) who, like most prostitutes, is a survivor of childhood sexual abuse. Bonnie's prostitution is part of the unconscious repetition compulsion common in trauma victims; by prostituting herself, Bonnie re-creates the scenario of sexual abuse that occurred during her childhood, while maintaining an illusion of control over the situation. We maintain that an effective approach to treatment for Bonnie is integrative therapy, a type of psychological counseling designed to address the major aftereffects of sexual abuse: dissociation from the body and sexuality in general; a profound sense of powerlessness; critically low valuation of the self; and mistrust and fear of intimacy. Bonnie's story shows the dynamics of both prostitute behavior and integrative therapy, providing an example we believe to be applicable far beyond this case study.     

From I: A/M to “Who am I?”—Aggregation/Massification and Trauma-Based Affects and Object Relations in Groups: A Response to Earl Hopper

Hopper's portrayal of the fourth basic assumption of Incohesion: Aggregation/Massification has two components: (1) a revision of Turquet's theory of BA Oneness to incorporate the polarity of aggregation and massification stemming from annihilation anxiety; and (2) a conception of the difficult patient as having an encapsulated psychosis. Hopper's theory of the encapsulated psychosis offers an important but incomplete perspective in explaining borderline and narcissistic pathology, as well as psychological trauma. In this response to Hopper, I suggest that the fourth assumption is in fact a still more primitive state of boundary opening and closing. I also see a need to differentiate trauma as such from borderline pathology, and further hold that the relationship between Hopper's British Independent theory and trauma theories based on dissociation needs to be clarified.
