Worry postponement, also called stimulus control, is a simple and easy to administer intervention that often forms part of cognitive-behavioural treatments for worry. We conducted a meta-analysis to test if worry postponement is effective in reducing daily worry. Data from 7 randomized trials were included providing a total of 999 participants, of which 250 experienced worry as a burden and of which the majority was women. When comparing worry postponement to the mere registration of worries small effect sizes were observed for worry duration (d = 0.313) and for worry frequency (d = 0.189). Moderation analyses showed that the intervention yielded larger effect sizes in studies including more women. However, long-term follow-up studies are still lacking. Worry postponement, practiced between a week or a maximum of a month, was found to effectively reduce the frequency and duration of worry in daily life. This suggests that a simple intervention is available for people whose worries (temporarily) spiral out of control. [ABSTRACT FROM AUTHOR]

Worry is a central process in a wide range of psychopathological and somatic conditions. Three studies (N = 856) were used to test whether a subscale composed of five items of the most commonly used trait anxiety questionnaire, Spielberger's State Trait Anxiety Inventory-Trait version (STAI-T), is appropriate to measure worry. Results showed that the subscale, named the Brief Worry Scale (BWS), had excellent internal consistency and temporal stability. Convergent and divergent validity were supported by correlation analyses using worry questionnaires and measures of anxious arousal and depression. The BWS was a particularly good predictor of the pathogenic aspects of worry, including worry perseveration in daily life (study 1), measures of clinical worry (study 2) and the uncontrollability of experimentally induced worry (study 3). Taken together, these studies demonstrate that the BWS might be a valuable scale for pathological worry, for which many researchers already have data. [ABSTRACT FROM AUTHOR]

The Levels of Emotional Awareness Scale (LEAS) is a well-validated performance measure of trait emotional awareness (EA), which is associated with psychological and physical problems. EA is, however, expected to vary over time and we aimed to adapt the LEAS to permit the measurement of EA in daily life as a function of momentary state. Twenty-five students completed 12 ecological momentary assessments (EMAs) of EA across 2 days. The correlation between the mean EMAs of EA and trait EA, and the change over time in EA, was also examined. Findings revealed a significant positive correlation between state and trait EA. The within-person reliability was substantial, suggesting that EMAs can reliably assess EA over time across individuals. Importantly, latent state-trait analysis showed that about 50% of EA variability was due to state variance whereas only 2% of EA variability was due to trait variance. Preliminary psychometric properties suggest that the developed method allows for the measurement of EA in daily life and supports the claim that EA can be measured using both hypothetical (as in the LEAS) and real-life (using EMAs) scenarios.

Background: Cognitive models explaining medically unexplained complaints propose that activating illness-related memory causes increased complaints such as pain. However, our previous studies showed conflicting support for this theory. Purpose: Illness-related memory is more likely to influence reporting of complaints when its activation is enmeshed with that of self-related memory. We, therefore, investigated whether inducing this association would cause a stronger decrease in pain tolerance. In addition, we examined whether SFA acted as a moderator of this effect. Methods: We used subliminal evaluative conditioning (SEC) to induce an association between activated self-related and illness-related memory. Seventy-six participants were randomly assigned to four combinations of two priming factors: (1) the self-referent word “I” versus the nonself-referent “X” to manipulate activated self-related memory and (2) health complaint (HC) words versus neutral words to manipulate activated illness-related memory. Pain tolerance was assessed using a cold pressor task (CPT). Results: Participants primed with the self-referent “I” and HC words did not demonstrate the expected lower pain tolerance. However, SFA acted as a moderator of the main effect of the self-prime: priming with “I” resulted in increased pain tolerance in participants with low SFA. Conclusions: The current study did not support the hypothesis that associations between activated self-related memory and illness-related memory cause increased reporting of complaints. Instead, activating self-related memory increased pain tolerance in participants with low SFA. This seems to indicate that the self-prime might cause an increase in SFA and suggests possible new ways to promote adaptive coping with pain. [ABSTRACT FROM AUTHOR]

Transcutaneous stimulation of the auricular branch of the vagus nerve (tVNS) may accelerate fear extinction in healthy humans. Here, we aimed to investigate this hypothesis in healthy young participants in a prepared learning paradigm, using spider pictures as conditioned stimuli. After a fear conditioning phase, participants were randomly allocated to receive tVNS (final N = 42) or sham stimulation (final N = 43) during an extinction phase. Conditioned fear was assessed using US expectancy ratings, skin conductance and fear potentiated startle responses. After successful fear acquisition, participants in both groups showed a reduction of fear over the course of the extinction phase. There were no between-group differences in extinction rates for physiological indices of fear. Contrary to previous findings, participants in the tVNS condition also did not show accelerated declarative extinction learning. Participants in the tVNS condition did have lower initial US expectancy ratings for the CS− trials than those who received sham stimulation, which may indicate an enhanced processing of safety cues due to tVNS. In conclusion, the expected accelerated extinction due to tVNS was not observed. The results from this study call for more research on the optimal tVNS stimulation intensity settings.
