Are there interactions among dysfunctional beliefs in obsessive compulsive disorder?

Contemporary cognitive models of obsessive-compulsive disorder emphasize the importance of various types of dysfunctional beliefs, such as beliefs about inflated responsibility, perfectionism and the importance of controlling one's thoughts. These beliefs have been conceptualized as main effects, each influencing obsessive-compulsive symptoms independent of the contributions of other beliefs. It is not known whether beliefs interact with one another in their influence on obsessive-compulsive symptoms. To investigate this issue, data from 248 obsessive-compulsive disorder patients were analyzed. Dependent variables were the factor scores on the 4 Padua Inventory subscales. Predictor variables were the factor scores from the 3 factors (inflated responsibility, perfectionism and controlling one's thoughts) of the Obsessive Beliefs Questionnaire and their 2- and 3-way interactions. Regression analyses revealed significant main effects; in almost all analyses one or more of inflated responsibility, perfectionism, and controlling one's thoughts factors predicted scores on the Padua factors even after controlling for general distress. There was no evidence that beliefs interact in their effects on obsessive-compulsive symptoms, thereby providing a relatively unusual instance in which a simpler explanation (main effects only) is just as powerful as a more complex model.     

How does context affect intimate relationships? linking external stress and cognitive processes within marriage

Stressors external to the marriage frequently affect the way spouses evaluate their marital quality. To date, however, understanding of the interplay between external stress and internal relationship processes has been limited in two ways. First, research has generally examined only the short-term consequences of stress. Second, the mechanisms through which external stressors influence relationship outcomes are unclear. This study addressed both limitations by examining relationship cognitions that may mediate the effects of external stress throughout 4 years of marriage. Analyses confirmed that stressful experiences were associated with the trajectory of marital quality overtime. Furthermore, both the content and the organization of spouses' specific relationship cognitions mediated this effect. That is, stress negatively influenced the nature of spouses' marital perceptions as well as the way spouses interpreted and processed those perceptions. These findings draw attention to ways that the context of relationships shapes and constrains relationship processes.     

Providing misleading and reinstatement information a year after it happened: effects on long-term memory

The question addressed here is whether misleading suggestions made to children a year after target events had occurred will alter long-term recall. One group (3-13 years old when injured and treated in a hospital Emergency Room) were given both misleading and accurate reinstating information a year later, and recall of target events assessed both 1 week and another year later (i.e., 2 years post-injury). A control group had recall assessed both 1 and 2 years post-injury. Misleading had little effect on children's recall 1 week later, although a few misled details were reported. However, a year later virtually none of the misleading information was incorporated into long-term recall. Rather, children were more, not less, accurate when recalling details about which they had been misled. Results were attributed to target events having been highly memorable and well rehearsed via previous recalls, and detection of discrepancies between memory and misleading information focusing attention on targeted details.     

Family Environments of Women Seeking BRCA1/BRCA2 Genetic Mutation Testing: An Exploratory Analysis

Although there is some understanding of the shared characteristics and predictors of psychological distress of women participating in hereditary breast and ovarian cancer registries, these same characteristics are only beginning to be identified in research on community women seeking genetic testing for BRCA1/BRCA2 gene mutations. This study provides an initial exploration of characteristics associated with family environments for 51 community women waiting to receive such genetic testing results. Thirty-four of the 36 women classified on family environment type of the Family Environment Scale (FES) were from Personal Growth-Oriented families. Comparisons of women with and without personal cancer histories resulted in a trend for women with personal cancer histories to be classified as from Independence-Oriented families. Reported distress appears to vary for different family emphases based on family and personal cancer history. A moral-religious family emphasis consistently appeared to be associated with decreased psychological distress. Preliminary analyses comparing these community women (who were not part of a hereditary registry but were self- or physician-referred) seeking genetic testing with normal and distressed family means found that increased cohesion and expressiveness may be related to decreased conflict, indicative of potentially supportive family environments for these women. When compared with normative data, a subset consisting of the Ashkenazi Jewish women showed a trend of less cohesion than normal families, but similar cohesion levels as distressed families.     

Linguistic Analysis of Written Narratives of Caregivers of Children and Adolescents with Chronic Illness: Cognitive and Emotional Processes and Physical and Psychological Health Outcomes

Used linguistic analysis of written narratives of caregivers of hospitalized youth with chronic illness to identify emotional and cognitive processes related to physical and psychological health outcomes following writing. Measures were administered at baseline and 4 months. Experimental group (n = 29) wrote about traumas whereas the control group (n = 24) wrote about summer activities for 20 min on three different days. Compared groups on negative emotion- and cognition-related word use. Tested change in negative emotion- and cognition-related word use as predictors of outcomes in experimental group. Consistent with hypotheses, experimental group used more negative emotion words [F(1, 53) = 77.55, p < .001] and cognition-related words than control group [F(1, 53) = 19.09, p < .001] and an increase in cognition words predicted Physical Health Summary Score on SF-36 (standardized = .37, p < .05). A decrease in negative emotion words was related to Physical Health Summary Score on SF-36 only when entered into regression with change in cognition words (standardized = –.31, p < .05). A decrease in negative emotion together with an increase in cognitive processing facilitated by written emotional disclosure has beneficial effects on physical health-related quality of life.     

Identifying environmental contributions to autism: provocative clues and false leads

The potential role of environmental factors in autism spectrum disorders (ASD) is an area of emerging interest within the public and scientific communities. The high degree of heritability of ASD suggests that environmental influences are likely to operate through their interaction with genetic susceptibility during vulnerable periods of development. Evaluation of the plausibility of specific neurotoxicants as etiological agents in ASD should be guided by toxicological principles, including dose-effect dependency and pharmacokinetic parameters. Clinical and epidemiological investigations require the use of sufficiently powered study designs with appropriate control groups and unbiased case ascertainment and exposure assessment. Although much of the existing data that have been used to implicate environmental agents in ASD are limited by methodological shortcomings, a number of efforts are underway that will allow more rigorous evaluation of the role of environmental exposures in the etiology and/or phenotypic expression of the disorder. Surveillance systems are now in place that will provide reliable prevalence estimates going forward in time. Anticipated discoveries in genetics, brain pathology, and the molecular/cellular basis of functional impairment in ASD are likely to provide new opportunities to explore environmental aspects of this disorder.     

Rising and surviving: a conceptual model of active coping among Black lesbians

This study tested a conceptual model of active coping among a predominantly middle-class sample (N = 92) of Black lesbians (ages 18 to 68) attending a Black lesbian retreat. F. B. Tyler's (1978) active coping dimension of psychosocial competence and L. P. Anderson, C. L. Eaddy, and E. A. Williams's (1990) psychosocial competence model for Black Americans emphasizing the role of individual and environmental factors provided the theoretical framework for the study. A theoretical model was developed to examine whether internal (self-esteem, race and lesbian identification) and external (social support, perceived available lesbian, gay, bisexual, and transgendered resources) factors predicted active coping. Results confirmed that the model of internal and external factors was a statistically significant predictor of active coping.     

Psychopathy is related to negative affectivity but not to anxiety sensitivity

Although the hypothesis that psychopathic individuals are characterized by a reduced capacity for experiencing anxiety is central to many theories of psychopathy, most prior studies have examined anxiety and fear measures generally considered outdated in the literature. Moreover, prior findings are mixed, with several studies reporting no relationships between psychopathy and anxiety, and others suggesting negative relationships for the affective, interpersonal aspects of the disorder and positive relationships for the antisocial behavior dimension. To examine whether psychopathy dimensions are associated with contemporary measures of anxiety, the Anxiety Sensitivity Index and State Trait Anxiety Inventory-Trait scale were administered to 157 male inmates. Participants also completed the MMPI-derived Welsh Anxiety Scale (WAS), commonly used in psychopathy studies. Analyses provide no evidence for a negative relationship between psychopathy's affective, interpersonal factor and anxiety sensitivity after controlling for trait anxiety. Trait anxiety and WAS scores were positively associated with the antisocial behavior dimension of psychopathy. Findings do replicate prior relationships between the WAS and psychopathy, suggesting the WAS may measure aspects of negative affectivity that differ from anxiety.
