Assessment of the hypochondriasis domain: the multidimensional inventory of hypochondriacal traits (MIHT)

Although hypochondriasis is associated with the costly use of unnecessary medical resources, this mental health problem remains largely neglected. A lack of clear conceptual models and valid measures has impeded accurate assessment and hindered progress. The Multidimensional Inventory of Hypochondriacal Traits (MIHT) addresses these deficiencies with scales that correspond to a 4-factor model. The MIHT was built with construct validity as a guiding principle and began with an item pool that broadly assessed dimensions identified in the literature. The items were administered to large samples; factor analyses of the responses led to item pool revisions and scale refinements. Multiple studies validated the final MIHT scales and 4-factor model; these findings suggest that the MIHT will contribute to theory and research.     

An Integrative Approach to Somatoform Disorders Combining Interpersonal and Cognitive-behavioral Theory and Techniques

Data regarding the treatment of somatoform disorders suggest that the gains associated with current psychopharmacologic or psychotherapeutic treatments are modest at best. There have been a few moderately effective treatments for selected functional somatic syndromes, but patients who present with multi-system symptoms meeting criteria for the DSM-IV somatoform disorders are notoriously unresponsive to treatment. Experts in the field have advocated several approaches, including interpersonally oriented and cognitive-behavioral therapies, and have emphasized the importance of the provision of reassurance within the doctor-patient relationship. While each individual approach has merit, none is likely to be maximally efficacious as a stand-alone treatment. In this article we describe the theoretical underpinnings and technical aspects of a treatment for somatizing patients that integrates these three elements.     

Food-related stimuli increase desire to eat in hungry and satiated human subjects

In the present study, the effect of food-related cues on the desire to eat chocolate in hungry and satiated subjects was investigated. Subjects (n=46) were randomly assigned to either a hungry or satiated group and then assigned to a group receiving one of the following stimuli: taste (2 M&Ms), sight (a photograph of M&Ms), cognition (a passage describin M&Ms), or control (no stimulus). In each testing session, subjects rated their desire to eat chocolate before and after the 90-s presentation of the particular stimulus. Each subject was then given a half pound of M&Ms so that actual consumption could also be measured. Results indicated that, following the presentation of the sight and taste stimuli, the subjects’ desire to eat chocolate was significantly increased. Furthermore, no differences in chocolate consumption due to state of hunger or type of food-related stimulus presented were found.     

Web Site Design, Self-Monitoring Style, and Consumer Preference

This study aims to advance understanding of Internet interactions by considering the impact of Web site design and self-monitoring style on consumer preference. Four quasi-commercial Web sites were constructed containing identical information presented via a context-based (animated) or content-based (unanimated) design, and 2 advertisements of either image- or information-oriented style. Using a between-participants design, the study found that all individuals favored context-based over content-based Web site design. Matching advertising appeal to individual self-monitoring needs was found to increase Web site effectiveness of consumer preference for high self-monitors, and within Web site satisfaction and level of persuasion for low self-monitors. Results suggest that to reach their potential as a consumer-sensitive tool, Web sites must be engaging in their design and tailor their communications to accommodate individual differences.

Attention-Deficit/Hyperactivity Disorder Symptoms in Mothers and Fathers: Family Level Interactions in Relation to Parenting

Previous studies linking parent ADHD symptoms to parenting have typically focused on each parent individually. To provide a broader understanding of family context, in this study, levels of inattention and hyperactivity-impulsivity in mothers and fathers were examined, both individually and in combination, in relation to negative parenting and child-rearing disagreements. Two-parent families of 5 to 13 year old boys (126 with ADHD and 53 typically developing) participated. Parents reported their own ADHD symptoms and their perceptions of child-rearing disagreements. Parenting was measured using self-, partner-, and child-reports as well as observations. Controlling for child ADHD symptoms, inattention symptoms in fathers predicted parenting difficulties. For mothers, inattention symptoms were linked to parenting problems only when fathers also had high levels of inattention. In contrast, parenting was most problematic for both mothers and fathers in families in which fathers had higher and mothers had lower levels hyperactivity-impulsivity symptoms. These results remained essentially unchanged when child externalizing behavior and mother depression and hostility were controlled, but father depression reduced the significance of some interactions. The results highlight the importance of the match between father and mother levels of symptoms, and point to differential relations of parenting to inattention and hyperactivity-impulsivity symptoms in parents.     

The effect of perspective-taking on reasoning about strong and weak belief-relevant arguments

This study investigated whether perspective-taking reduces belief bias independently of argument strength. Belief bias occurs when individuals evaluate belief-consistent arguments more favourably than belief-inconsistent arguments. Undergraduates (n = 93) read arguments that varied with respect to belief-consistency (i.e., belief-consistent or belief-inconsistent) and strength (i.e., strong or weak) about the topic of climate change. After participants read each argument, those in the perspective-taking condition rated the argument's strength from a perspective of a climate scientist and then from their own perspectives, whereas those in the no perspective-taking condition only rated the arguments from their own perspectives. Perspective-taking eliminated belief bias for weak arguments, but not for strong arguments. Theoretical and practical implications of the results are discussed, and directions for future research are provided.
