Health Anxiety: Latent Structure and Associations with Anxiety-related Psychological Processes in a Student Sample

Although currently classified as a somatoform disorder, cognitive-behavioral models conceptualize hypochondriasis (HC) as a severe form of health anxiety. The Short Health Anxiety Inventory (SHAI) is a measure derived from this conceptualization that measures health anxiety symptoms across the range of severity. Previous studies have reported inconsistent findings regarding this measure’s factor structure, but these studies employed factor analytic tools that did not account for the categorical nature of SHAI items. The present psychometric study was designed to address these inconsistencies using categorical factor analysis. Using data from a large student sample we found that the SHAI had two factors: Illness Likelihood and Illness Severity. We also examined the relationship between these domains and cognitive variables associated with other anxiety disorders. Results suggested that the psychological processes present in obsessive-compulsive disorder and panic disorder are also associated with health anxiety. Implications for the conceptualization and classification of severe health anxiety are discussed.     

The relationship between religion and thought-action fusion: Use of an in vivo paradigm

Research has demonstrated that higher levels of religiosity are positively correlated with thought-action fusion (TAF), a set of cognitive biases found to be associated with obsessive-compulsive symptoms. However, previous studies have exclusively relied on a nomothetic approach to measuring TAF using a single self-report instrument, the thought-action fusion scale. The current study examined the relationship between religiosity and TAF using an in vivo behaviorally-based assessment in which participants thought about and wrote down thoughts of negative events involving loved ones. Forty-three highly religious Protestant Christians were compared to 30 Atheists/Agnostics on their in vivo ratings of anxiety, estimates of likelihood, and moral wrongness related to the negative thoughts. Results indicated that compared to the non-religious participants, those who were highly religious believed that writing and thinking about the negative events was more morally wrong and increased the likelihood of the event. Results are discussed in terms of the potential relationship between certain religious teachings and TAF-related beliefs about the importance, significance, and influence of thoughts.     

The relationship between obsessive beliefs and symptom dimensions in obsessive-compulsive disorder

Research findings on the specific relationships between beliefs and OCD symptoms have been inconsistent, yet the existing studies vary in their approach to measuring the highly heterogeneous symptoms of this disorder. The Dimensional Obsessive-Compulsive Scale (DOCS) is a new measure that allows for the assessment of OCD symptom dimensions, rather than types of obsessions and compulsions per se. The present study examined the relationship between OCD symptom dimensions and dysfunctional (obsessive) beliefs believed to underlie these symptom dimensions using a large clinical sample of treatment-seeking adults with OCD. Results revealed that certain obsessive beliefs predicted certain OCD symptom dimensions in a manner consistent with cognitive-behavioral conceptual models. Specifically, contamination symptoms were predicted by responsibility/threat estimation beliefs, symmetry symptoms were predicted by perfectionism/certainty beliefs, unacceptable thoughts were predicted by importance/control of thoughts beliefs and symptoms related to being responsible for harm were predicted by responsibility/threat estimation beliefs. Implications for cognitive conceptualizations of OCD symptom dimensions are discussed.     

Interference resolution in major depression

In two experiments, we investigated individual differences in the ability to resolve interference in participants diagnosed with major depressive disorder (MDD). Participants were administered the “Ignore/Suppress” task, a short-term memory task composed of two steps. In Step 1 (“ignore”), participants were instructed to memorize a set of stimuli while ignoring simultaneously presented irrelevant material. In Step 2 (“suppress”), participants were instructed to forget a subset of the previously memorized material. The ability to resolve interference was indexed by response latencies on two recognition tasks in which participants decided whether a probe was a member of the target set. In Step 1, we compared response latencies to probes from the to-be-ignored list with response latencies to nonrecently presented items. In Step 2, we compared response latencies to probes from the to-be-suppressed list with response latencies to nonrecently presented items. The results indicate that, compared with control participants, depressed participants exhibited increased interference in the “suppress” but not in the “ignore” step of the task, when the stimuli were negative words. No group differences were obtained when we presented letters instead of emotional words. These findings indicate that depression is associated with difficulty in removing irrelevant negative material from short-term memory.     

The effectiveness of psychotherapeutic interventions for bereaved persons: a comprehensive quantitative review

Previous quantitative reviews of research on psychotherapeutic interventions for bereaved persons have yielded divergent findings and have not included many of the available controlled outcome studies. This meta-analysis summarizes results from 61 controlled studies to offer a more comprehensive integration of this literature. This review examined (a) the absolute effectiveness of bereavement interventions immediately following intervention and at follow-up assessments, (b) several of the clinically and theoretically relevant moderators of outcome, and (c) change over time among recipients of the interventions and individuals in no-intervention control groups. Overall, analyses showed that interventions had a small effect at posttreatment but no statistically significant benefit at follow-up. However, interventions that exclusively targeted grievers displaying marked difficulties adapting to loss had outcomes that compare favorably with psychotherapies for other difficulties. Other evidence suggested that the discouraging results for studies failing to screen for indications of distress could be attributed to a tendency among controls to improve naturally over time. The findings of the review underscore the importance of attending to the targeted population in the practice and study of psychotherapeutic interventions for bereaved persons.     

Repeated Behavior and Environmental Psychology: The Role of Personal Involvement and Habit Formation in Explaining Water Consumption1

Extending existing theory in social and environmental psychology, we develop a model to study important predictors of water consumption behavior. Overall results provide support for the predictive ability of stimuli (e.g., environmental awareness), reasoned processes (e.g., personal involvement), unreasoned processes (e.g., habits), and situational factors (e.g., income) on water consumption behavior. Findings indicate that households with lower water usage display greater awareness of water conservation issues, are more highly involved in the decision to use water, and tend to form habits associated with lower usage levels. Furthermore, the results are consistent with past research that attitudes toward water usage appear to be poor predictors of water consumption behavior. After controlling for situational factors (e.g., household size), the findings substantiate the role of personal involvement and habit formation in explaining water consumption, lending further support to the adaptation and development of repeated behavior models in environmental psychology.     

Binding feature dimensions in visual short-term memory

We explored several possible influences on binding in visual short-term memory (VSTM) performance. The task was to report whether a test object was the same (“old” trials) or different (“new” trials) from any of the sample objects seen a second ago. The objects were composed of two features that varied from continuous to discrete shapes and colors. In “old” trials the test object appeared either in the same or different position. In “new” trials the test object differed along both features, requiring storage of only one feature per object; along one feature, requiring no binding but storage of all features; or it was created by recombining features from the sample, which requires binding. Existing storage hypotheses are unable to explain the similar sensitivity (d′) obtained in the two last conditions when position remained the same and may suggest that links are created between positions and features. Highest sensitivity occurred when the test object remained at the same position, required no binding, and discrete features were used. Object-type × position, and feature combination × position interactions occurred, suggesting different storage modes depending on whether objects change position during retention.     

Voices of Outreach: The Construction of Identity and Maintenance of Social Ties Among Chabad-Lubavitch Emissaries

Fundamentalists typically avoid influences from the outside world and form intense social bonds with members of their own group. Yet, active fundamentalists must create relationships with the objects of their missionary action, the Other. In this article I address the connections between the cultural practice of missionary work and the formation and maintenance of social ties among ultra-Orthodox Jewish missionaries belonging to the fundamentalist Hasidic sect Chabad-Lubavitch. These missionaries attempt to bring Jews to the beliefs and practices of Chabad by hosting Jews at Sabbath meals. This missionary act is an utterance that "speaks" with multiple voices, indexing the missionaries as both friendly members of their local Jewish community and ideal Lubavitchers. Through these meals, the missionaries engage not only the local Jews but also other Lubavitchers in dialogue, constructing a community that transcends face-to-face interaction.
