The Interpersonal Model of Health Anxiety: Testing predicted paths and model specificity

Health anxiety involves persistent worry about one’s health and is characterized by dysfunctional interpersonal processes such as excessive health-related reassurance-seeking and feelings of alienation from others. Cognitive-behavioral models largely ignore cyclical, interpersonally averse behaviors and social cognitions observed amongst health anxious individuals. The Interpersonal Model of Health Anxiety (IMHA) proposes health anxiety is maintained through activated anxious attachment insecurities, which drive frequent, but ineffective, health-related reassurance-seeking from others. Such excessive health-related reassurance-seeking leads to health-related alienation and beliefs others are unconcerned about one’s perceived health problems. Feeling alienated from others fuels further health-related worry, resulting in continued self-defeating attempts at health-related reassurance-seeking. The present study offers the first comprehensive articulation and test of the IMHA. Using a cross-sectional design and 107 undergraduates, path analysis supported five of six hypothesized paths in the model; all paths except that from anxious attachment to health-related reassurance-seeking were significant and in the expected direction. Specificity tests suggested anxious attachment was more central than avoidant attachment to the IMHA. The present test of the IMHA as a single, coherent model provides a conceptual foundation for future research on interpersonal processes in health anxiety. Clinical implications are discussed.     

The Effect of Target Status on Witnesses' Reactions to Confrontations of Bias

HIV-related stigmatization remains prevalent and harmful to HIV+ individuals. Guided by a dual process model of HIV-related stigma, this study examined the psychological factors governing stigmatizing responses and response adjustments toward HIV+ persons. Hypotheses were tested using a computerized stigma measure that simulated approach/avoidance behavior toward an HIV+ target. Findings indicated that initial reactions to the HIV+ target were predominately negative and associated with endorsement of homophobia. Conversely, subsequent response adjustments reflected greater acceptance of the HIV+ target and were associated with internal motivations to control prejudice. Findings confirm the need for innovative stigma reduction strategies.     

When Sociopolitical Events Strike Cultural Beliefs: Divergent Impact of Hurricane Katrina on African Americans' and European Americans' Endorsement of the Protestant Work Ethic

Three experiments address how people react to a sexual abuse victim compared to a nonvictim when a justification for negative evaluation is available or not available. A harm-doing victim was rated lower on expected job performance and higher on desired social distance than a harm-doing nonvictim. When subsequent harm-doing was absent, judgments of a victim and nonvictim did not differ on expected job performance or social distance. Experiment 2 replicated the results of Experiment 1 and revealed that the order in which victimization history and harm-doing information were presented had no effect. Experiment 3 showed that participants desired greater social distance from a harm-doing victim compared to a non-harm-doing victim to the extent they thought the target should have derived benefits from the childhood victimization. Implications for judgments of harm-doers—depending on whether their victimization history is known or not—are considered.     

Do gains in working memory capacity explain the written self-disclosure effect?

Klein and Boals (2001) concluded that expressive writing about negative life events improves health by reducing intrusive thoughts, as measured by the Impact of Events Scale (IES), and thus freeing working memory (WM) capacity. We replicated their WM gain and rejected the possibility that it reflected task practice alone. We extended their work by showing that such WM effects and reductions in self-reported health symptoms can be observed within a short time frame of a week in a normal population of college students and can occur without reductions in IES scores. Two alternative explanations are discussed of how WM gains can be observed in the written self-disclosure effect without reductions in the frequency of intrusive thoughts and avoidance attempts.     

Semantic processing in auditory lexical decision: Ear-of-presentation and sex differences

In this study we examined the interplay between appetitive (approach) and defensive (avoid) responses in spoken word recognition. Ninety-two right-handed participants (half women) took part in an auditory lexical decision experiment in which speech was presented to only one ear. The danger and usefulness of the word referents interacted in predicting RTs, as in previous (binaural) studies with poorer control of psycholinguistic covariates. Specifically, higher danger ratings were associated with faster RTs for words rated low on usefulness; but higher danger ratings were associated with slower RTs for words rated high on usefulness. In addition to this primary finding, men showed more lateralised performance, as indicated by significant interactions of sex and ear of presentation with word frequency, and with the animacy of the word referents. For both sexes, word frequency had a stronger effect on accuracy for speech presented to the right ear. Finally, men's but not women's RTs were related to the danger dimension. This last finding provides an intriguing avenue for future research in the area of sex differences and emotion.     

Strength of affective reaction as a signal to think carefully

Analytic processes reduce biases, but it is not known how or when these processes will be deployed. Based on an affective signal hypothesis, relatively strong affective reactions were expected to result in increased analytic processing and reduced bias in judgement. The valence and strength of affective reactions were manipulated through varying outcomes in a game or evaluative conditioning of a stimulus. Relatively strong positive or negative affective reactions resulted in less desirability bias. Bias reduction only occurred if participants had time to deploy analytic processes and indicators of the degree of analytic processing (in the form of attentional control) predicted less bias. Affective processes have long been acknowledged as a source of bias, but these findings suggest affective processes are also integral to bias reduction.     

Functional Analysis Identified Habit Reversal Components for the Treatment of Motor Tics

This study included brief functional analyses and treatment for motor tics exhibited by two children with Tourette Syndrome. Brief functional analyses were conducted in an outpatient treatment center and results were used to develop individualized habit reversal procedures. Treatment data were collected in clinic for one child and in clinic and school for the other child. Brief functional analysis results were mixed for each child, but provided useful information for informing unique habit reversal components for each child. Treatment results indicated reductions in motor tics for each child. Results are discussed in terms of utility of functional analysis for tics.     

United Kingdom Mission Training Through Distributed Simulation

This paper presents the findings of a United Kingdom (UK) research program carried out over the last decade. This research has explored the benefits of using networks of simulators for collective training known in the UK as mission training through distributed simulation (MTDS). The paper provides an overview of trials carried out to date, identifies the research issues addressed, and discusses the key findings. The conclusion is that MTDS provides an immersive training environment that has the potential to support not only single service collective training, but also joint and coalition training requirements.     

Trainee Perceptions of Drill Sergeant Qualities During Basic Combat Training

Basic combat training plays an important role in military service with approximately 72,000 soldiers participating in the United States annually. Although Drill Sergeant qualities have been widely portrayed in popular media, there is very little empirical research that documents the characteristics of Drill Sergeants and the impact these characteristics may have on trainees. In this study we evaluated a measure of perceived Drill Sergeant qualities and the degree to which these qualities related to mental health symptoms and job-related outcomes of trainees. Three types of perceived Drill Sergeant qualities were found from factor analyses: motivation, respect, and toughness. Using latent growth curve analyses, higher initial scores on motivation and respect, but not toughness, were associated with greater decreases in mental health symptoms over time. Further, changes in perceived Drill Sergeant qualities related to changes in depressive symptoms, unit cohesion, and citizen behaviors assessed over the course of basic combat training.     

Prospective Memory and Pediatric Traumatic Brain Injury: Effects of Cognitive Demand

This study investigated the effects of pediatric traumatic brain injury (TBI) on prospective memory. Fourteen children and 14 adolescents with TBI were compared with 25 and 23 noninjured children and adolescents, respectively. Based on a prefrontal model, the cognitive demand on the ongoing component of a prospective-memory task was manipulated. Overall, those with TBI had poorer prospective-memory performance than their noninjured peers. Performance was worse in a high cognitive-demand condition than a low, and younger children performed worse than adolescents. Decreases in performance from the low- to high-demand conditions were not significantly different between the two children's groups but were between the two adolescents' groups. Furthermore, the age and injury effects were reflected in the performances on executive function tests: the Self-ordered Pointing Task (SOPT), and the Stroop Color Word Interference Test. The Tower of London (TOL), which did not produce age or injury effects, was nevertheless found to be an important predictor of performance on the high-demand task in those with TBI. Although previous research has demonstrated impaired prospective memory performance in children with TBI, this study attempted to explain why this might occur, specifically that the prefrontal regions might be implicated.
