Methods and mechanisms in the efficacy of psychodynamic psychotherapy

Comments on the original article, "The efficacy of psychodynamic psychotherapy," by J. Shedler (see record 2010-02208-012). Shedler summarized a large body of research that shows psychodynamic therapy to have a substantial effect size, comparable to that for many empirically supported treatments. This is an important finding, in part refuting the concerns raised by Bornstein (2001, 2002) regarding the future of psychodynamic approaches had there been no substantial changes in how practitioners and researchers approached the science to demonstrate efficacy. Further, Shedler showed that the efficacy of psychoanalytic psychotherapy is due to therapeutic methods commonly employed in cognitive behavior therapy (CBT), one of the most frequently cited empirically supported approaches for a wide range of psychological conditions. From a methodological perspective, there are some important limitations to the claim of psychodynamic psychotherapy's comparable efficacy to other empirically supported approaches.     

The Relationship Between Nonclinical Schizotypy and Handedness on Divergent and Convergent Creative Problem-Solving Tasks

Previous research indicated a relationship between hemispherical dominance, the extent of schizotypal tendencies, and creativity. Little research has been conducted to assess the degree of schizotypy in nonclinical samples. The aim of this study was to determine the extent to which measures of multidimensional schizotypy and predominant handedness could predict measures of creativity, as assessed by both divergent and convergent tasks. One hundred and twenty-six participants participated in a quasi-experiment involving tests of predominant handedness, schizotypal tendencies, and divergent and convergent thinking. Results suggest that individuals who scored high on a test for schizotypal tendencies performed better on divergent problem-solving tasks, as opposed to low scoring individuals who performed better on convergent problem-solving tasks. Furthermore, results suggest that there was relationship between handedness on divergent and convergent thinking. There was, however, a relationship between handedness (right hemisphere) on the degree of schizotypal tendencies with left-handed individuals demonstrating greater schizotypal tendencies.     

Behavioral avoidance tests and disgust in contamination fears: distinctions from trait anxiety

Much of the existing literature examining the role of disgust is limited to specific phobia. Recent research has begun to examine the role of disgust in contamination fear, a subtype of obsessive-compulsive symptoms. Through the use of behavioral avoidance tasks (BATs), the current study was designed to examine the role of disgust in people with contamination fears, with attention to distinguishing high and low trait anxiety. From a large screening of undergraduate students, three groups were formed based on their level of contamination fear and level of trait anxiety: contamination fearful ( n = 12 ), high-trait anxiety ( n = 11 ), and low trait anxiety ( n = 15 ). Subjects were asked to engage in six different BATs corresponding to six domains of disgust (food, animals, body products, body envelope violations, death, and sympathetic magic). One-way analysis of variance (ANOVA) showed significant differences between the contamination fearful group and the high trait anxiety group on the animal and sympathetic magic BATs. Significant differences on the food, animal, body envelope violations, and death BATs were also found between the contamination fearful group and the low-trait anxious group. The findings modestly support the importance of disgust in contamination fears. Implications for the study of disgust in contamination fear are provided.     

Comparison of polygraph data obtained from individuals involved in mock crimes and actual criminal investigations

In a preliminary attempt to determine the generalizability of data from laboratory mock-crime studies, the authors examined the similarities and differences among the cardiovascular, electrodermal, and respiration responses of deceptive and nondeceptive individuals elicited to crime-relevant and crime-irrelevant questions. Participants in the laboratory group were randomly assigned to nondeceptive (n = 28) or deceptive (n = 27) treatment groups, and a mock-crime scenario was used. The field participants were confirmed nondeceptive (n = 28) or deceptive (n = 39) criminal suspects who underwent polygraph examinations between 1993 and 1997. The results indicated that there were salient differences between field and similarly obtained laboratory polygraph response measures. However, accuracy of laboratory participants' classifications using logistic regression analysis was not significantly different from field participants' classification accuracy.     

Contextual modulation of N400 amplitude to lexically ambiguous words

Though much is known about the N400 component, an event-related EEG potential that is sensitive to semantic manipulations, it is unclear whether modulations of N400 amplitude reflect automatic processing, controlled processing, or both. We examined this issue using a semantic judgment task that manipulated local and global contextual cues. Word triplets (prime-noun-target, e.g., finance-bank-money) were sequentially presented on a computer screen (500 ms duration, 1000 ms stimulus onset asynchrony), in which the second word was a homograph. The first word (prime) created a neutral-, dominant-meaning- or subordinate-meaning-biased "global context," and the third word (target) created a dominant- or subordinate-biased "local context" that was either congruent or incongruent with the "global context" established by the first prime word. Participants were instructed to read all three words but to decide only whether the second and third words were semantically related. Event-related potentials (ERPs), specifically the N400, were recorded to the third terminal word. N400 amplitudes evoked by dominant meaning-related third words incongruent with the globally biased subordinate context (e.g., river-bridge-money) were significantly more negative than dominant endings in neutral contexts (e.g., taxi-bank-money), but not different from unrelated filler triplets. In addition, there was some indication that left hemisphere, temporal-parietal electrode sites were associated with greater N400 negativity for dominant targets in conflicting subordinate global contexts than homologous right hemisphere electrode sites, the latter of which showed significant activation to subordinate meanings in cooperating contexts. Thus, N400 amplitude was more affected by global than local context suggesting that controlled processes may take priority over automatic processes in modulating N400 amplitude, especially for left hemisphere electrode sites.     

Counting your blessings: Positive memories among grateful persons

We conducted two studies investigating the relationship of gratitude to autobiographical memory of positive and negative life events. Gratitude was assessed with an attitudinal measure and college students were asked to recall both positive and negative events from their past. In both studies, a significant positive relationship was found between trait gratitude and a positive memory bias. In Study 2 it was found that gratitude still reliably predicted positive memory bias after controlling for depression. Further, it was found that a positive intrusive memory bias was associated with gratitude in both studies. Thus, an important component of gratitude may be an enhanced tendency to recall positive events from one's life.     

A baldrige process for ethics?

In this paper we describe and explore a management tool called the Caux Round Table Self-Assessment and Improvement Process (SAIP). Based upon the Caux Round Table Principles for Business — a stakeholder-based, transcultural statement of business values — the SAIP assists executives with the task of shaping their firm’s conscience through an organizational self-appraisal process. This process is modeled after the self-assessment methodology pioneered by the Malcolm Baldrige National Quality Award Program. After briefly describing the SAIP, we address three topics. First, we examine similarities and differences between the Baldrige approach to corporate self-assessment and the self-assessment process utilized within the SAIP. Second, we report initial findings from two beta tests of the tool. These illustrate both the SAIP’s ability to help organizations strengthen their commitment to ethically responsible conduct, and some of the tool’s limitations. Third, we briefly analyze various dimensions of the business scandals of 2001–2002 (Enron, WorldCom, Tyco, etc.) in light of the ethical requirements articulated with the SAIP. This analysis suggests that the SAIP can help link the current concerns of stakeholders — for example, investors and the general public — to organizational practice, by providing companies with a practical way to incorporate critical lessons from these unfortunate events. An earlier version of this paper was presented at the “Ethics and Social Responsibility in Engineering and Technology” meeting, New Orleans, 2003.     

Internet-based intervention for mental health and substance use problems in disaster-affected populations: a pilot feasibility study

Early interventions that reduce the societal burden of mental health problems in the aftermath of disasters and mass violence have the potential to be enormously valuable. Internet-based interventions can be delivered widely, efficiently, and at low cost and as such are of particular interest. We describe the development and feasibility analysis of an Internet-delivered intervention designed to address mental health and substance-related reactions in disaster-affected populations. Participants (n = 285) were recruited from a cohort of New York City-area residents that had been followed longitudinally in epidemiological research initiated 6 months after the terrorist attacks of September 11, 2001. The intervention consisted of 7 modules: posttraumatic stress/panic, depression, generalized anxiety, alcohol use, marijuana use, drug use, and cigarette use. Feasibility data were promising and suggest the need for further evaluation.     

The structure of childhood obsessions and compulsions: dimensions in an outpatient sample

While obsessive-compulsive disorder (OCD) is defined as a unitary condition, prior research has identified meaningful and distinct symptom dimensions in adult samples. In contrast, there have been no investigations of symptom dimensions in samples of children diagnosed with OCD. The present study sought to address this gap. Children diagnosed with OCD (n = 137) were administered the Children's Yale-Brown Obsessive-Compulsive Scale symptom checklist and severity index. Symptoms were analyzed using principal components analysis. As with adult samples, four factors were identified from the checklist. However, these four factors (compulsions, sexual/aggressive obsessions, superstitions, and hoarding/ordering/somatic concerns) were different in content from adult studies. Further, several symptoms significantly contributed to more than one dimension. Each dimension was significantly correlated with scores from the severity index, with the exception of the obsession score with the hoarding/ordering/somatic concerns factor. Results suggest that there are distinct dimensions of symptoms in childhood OCD, but that these dimensions do not correspond to those identified in adults. Instead, it appears that some factors share variance, and the dimensions themselves are separated based upon developmental trajectories. The dimensions examined may be useful in future treatment studies using pharmacological and/or behavioral interventions.
