Do beliefs about the utility of worry facilitate worry?

Various theoretical models have pointed out the role of positive beliefs in the worry process ( [Dugas et al., 1998] and [Wells, 1995]). Two studies were conducted to search for experimental support for this possibility. After trait worry was controlled, a persuasion procedure was used to induce diverse beliefs about worry (positive, negative, or neutral). It was hypothesized that participants persuaded of the usefulness of worry would be more worried and more anxious after listening to a worrisome message. In the first study, 90 participants (62 females and 28 males) were exposed to a novel worrisome message, and in the second study, 60 participants (34 females and 26 males) were exposed to a more personally relevant worry. Results indicate that persuasion about the utility of worry does not trigger worry, and when prior positive beliefs about worry were controlled, they do not correlate with the change in anxiety after worrisome induction.     

Is worry a thought control strategy relevant to obsessive-compulsive disorder?

Thought control strategies are implicated in the development and maintenance of obsessive-compulsive disorder (OCD). Regarding one strategy – worry – extant data provide equivocal conclusions as to its relevance to OCD. The current study examined whether worry is an OCD-relevant thought control strategy using data from a large (N = 376) nonclinical sample. This investigation tested whether worry interacted with obsessive beliefs (perfectionism/certainty; responsibility/threat estimation; importance/control of thoughts) to predict the occurrence of ego-dystonic intrusive thoughts. As expected, worry did interact with obsessive beliefs to predict more reported intrusions. Contrary to expectations, worry interacted with all three assessed belief dimensions. These results provide support for conceptualizing worry as an OCD-relevant thought control strategy, which has both conceptual and therapeutic implications.     

Concern or confidence? Adolescents' identity capital and future worry in different school contexts

This present study investigated the roles identity capital and school's socio-economic status have on adolescent worry about future education, employment, and social status. The 354 participants were 14- to 15-year-old students from affluent (56.8%) and disadvantaged (43.2%) Finnish lower secondary schools. Structural equation modelling was used to test the hypothesis that a higher level of family-related identity capital is connected to a lower level of future worry, and that this connection is mediated through intrapersonal forms of identity capital, specifically academic self-concept and general self-efficacy. Adolescent future worry was also examined across school status with an independent samples t-test. The findings suggest that, in the relatively equal societal context in Finland, adolescents are rather confident about their future education, employment, and social status regardless of the socio-economic status of the school they attend, and when their level of identity capital is high the future worry decreases further.     

Efficacy of safety signals in the epilepsy monitoring unit (EMU): should we worry?

There is little consensus regarding the critical safety measures to prevent harm in epilepsy monitoring units (EMUs). We sought to determine whether the safety signals (SS) triggered during EMU events differed by seizure type and the efficacy of SS in alerting responders. We screened 468 consecutive EMU admissions from January 2008 until April 2011 for definitive events to evaluate the first 50 events of complex partial seizures (CPS), generalized tonic-clonic seizures (GTC), and psychogenic non-epileptic seizures (PNES). Response to telemetry signal was slower than to push button (PB). When there was PB alarm, response time was slower in patients with PNES. A higher proportion of PNES were triggered by PB. A greater percentage of epileptic seizures were missed compared with PNES. Future studies investigating more effective techniques to capture every epileptic seizure are warranted as 24/7 monitoring by healthcare professionals is not feasible in many settings.     

The effect of stereotype threat on older people’s clinical cognitive outcomes: investigating the moderating role of dementia worry

Objective: Numerous studies have shown that stereotype threat (ST) reduces older people’s cognitive performance, but few have studied its impact on clinical cognitive outcomes. Our study was designed to further examine the impact of ST on the clinical assessment of older subjects’ cognitive functioning, as well as the moderating role of fear of Alzheimer’s Disease (AD) (or ‘dementia worry’). Method: Seventy-two neurologically normal (MMSE > 26) participants aged between 59 and 70 completed a set of neuropsychological tasks in either an ST or a positive condition (condition in which negative stereotypes were invalidated). Results: Regression-based path analyses showed that only participants who expressed moderate or high fear of AD underperformed on executive tasks in the ST condition compared to their counterparts in the positive condition. Moreover, in the ST condition, participants’ performance on executive tasks was more impaired (relative to normative data) than in the positive condition. However, ST had no effect on memory and attention performance. Discussion: Our results showed that ST can cause older people to perform at pathological levels on executive tasks. Results highlight the need for clinicians to be cautious when conducting neuropsychological assessments of older people who express high levels of dementia worry.     

A sensitive body or a sensitive mind? Associations among somatic sensitization, cognitive sensitization, health worry, and subjective health complaints

OBJECTIVES: Psychobiological sensitization and health worry appear to be involved in the etiology of clinical manifestations of subjective health complaints (SHCs) via amplified processing of health-related information. However, it is not clear whether sensitization and health worry are also associated with common SHCs, which are extremely prevalent and are responsible for a large part of both human suffering and health care costs. In this study, we investigated whether SHCs are associated with health worry and two types of sensitization: cognitive health-related sensitization and somatic sensitization. We also examined whether health worry mediates the relationship between cognitive sensitization and SHCs and whether both levels of sensitization interact. METHODS: A nonclinical sample of 47 female students completed questionnaires about their recent subjective health as well as health worry and underwent tests for cognitive sensitization, operationalized as Stroop interference and free recall performance, and somatic sensitization, operationalized as pain tolerance and pain threshold in a cold pressor task. RESULTS: Severity of health complaints was positively related with recall of health-related stimuli, but not with Stroop interference, and with worrying about health complaints. In addition, worry mediated the relationship between recall bias and severity of health complaints. Both the number and severity of recent health complaints were associated with pain tolerance. Pain threshold was associated with Stroop interference for health-related information. CONCLUSIONS: The results suggest that specific types of cognitive sensitization and somatic sensitization are associated with common health complaints and that worrying about one's complaints might play a role by enhancing biased memory of health-related information.     

Discriminating between generalized anxiety disorder and anxiety disorder not otherwise specified in a Hispanic population: Is it only a matter of worry?

One hundred and two Hispanic persons who presented for treatment at a specialized anxiety disorders clinic were evaluated at intake using the Anxiety Disorders Interview Schedule-Revised (ADIS-R; DiNardo and Barlow [1988] Albany: Center for Stress and Anxiety Disorders, State University of New York at Albany). Results indicated that 14% of these patients suffered from anxiety and/or affective disorders that were not adequately captured by our current diagnostic system. Given that the majority of these cases were characterized by predominantly anxious features, further investigation was undertaken to determine the degree of overlap between these patients (anxiety disorder, not otherwise specified; NOS) and those with generalized anxiety disorder (GAD). The two groups differed only with regard to the number of excessive worries they reported and not in terms of somatic symptomatology, psychosocial stressors, or demographic variables. These data suggest that excessive worry may be a discriminating factor between the GAD and NOS groups, providing support for the notion of GAD as a disorder of chromic worry. Future research is needed to tease apart the relative influences of culture and socioeconomic status on our findings. Depression and Anxiety 5:1–6, 1997. © 1997 Wiley-Liss, Inc.
