The effects of safety behaviors on the fear of contamination: an experimental investigation

The strategies used by anxious individuals to prevent feared outcomes, known as safety behaviors, are thought to maintain pathological anxiety by preventing the disconfirmation of inaccurate threat beliefs. However, it is possible that safety behaviors might also contribute to the development and exacerbation of anxiety symptoms. The present study tested this notion in a sample of undergraduate participants with either low (n=30) or high (n=26) levels of contamination fear. After a week-long baseline period, participants spent 1 week engaging in a clinically representative array of contamination-related safety behaviors on a daily basis, followed by a second baseline period. Subsequent to the safety behavior manipulation, participants evidenced statistically significant increases in threat overestimation, contamination fear symptoms, and emotional and avoidant responses to three contamination-related behavioral avoidance tasks (BATs). In contrast, anxiety and depressive symptoms remained stable. The magnitude of change in contamination concerns was equivalent among participants in both contamination fear groups. Our findings suggest that contamination-related safety behaviors elicit a modest and specific increase in the fear of contamination. Possible mechanisms for this effect, as well as implications for the role of safety behaviors in the psychopathology of anxiety disorders, are discussed.     

Coping self-efficacy mediates the effects of negative cognitions on posttraumatic distress

Although cognitive distortions have predicted posttraumatic distress after various types of traumatic events, the mechanisms through which cognitive distortions influence posttraumatic distress remain unclear. We hypothesized that coping self-efficacy, the belief in one's own ability to manage posttraumatic recovery demands, would operate as a mediator between negative cognitions (about self, about the world, and self-blame beliefs) and posttraumatic distress. In the cross-sectional Study 1, data collected among 66 adult female victims of child sexual abuse indicated that coping self-efficacy mediated the effects of negative cognitions about self and about the world on posttraumatic distress. The same pattern of results was found in a longitudinal Study 2, conducted among 70 survivors of motor vehicle accidents. Coping self-efficacy measured at 1 month after the trauma mediated the effects of 7-day negative cognitions about self and about the world on 3-month posttraumatic distress. In both studies self-blame was not related to posttraumatic distress and the effect of self-blame on posttraumatic distress was not mediated by coping self-efficacy. The results provide insight into a mechanism through which negative cognitions may affect posttraumatic distress and highlight the potential importance of interventions aimed at enhancing coping self-efficacy beliefs.     

Workgroup Temperance of Alcohol and Safety Climate Moderate the Cognitive Effects of Workplace Substance‐Abuse Prevention1

This research examined the independent and combined influence of workgroup drinking norms and safety climate on the cognitive outcomes of prevention. Employees from 72 workgroups (n = 347) were randomly assigned to attend 1 of 2 training conditions or a control group that did not receive training until after follow‐up questionnaires. Results from hierarchical regression analyses showed there was a significant effect of the interaction between safety climate, drinking norms, and training on beliefs that policy and the employee assistance program are effective. Informational training was least effective for employees from relatively temperate workgroups. Team awareness was less effective for employees from tolerant groups. Employees might benefit more from interventions tailored to individual and workgroup cultural factors.     

Eye movements when looking at print advertisements: the goal of the viewer matters

Viewers looked at print advertisements as their eye movements were recorded. Half of them were asked to rate how much they liked each ad (for convenience, we will generally use the term ‘ad’ from this point on), while the other half were asked to rate the effectiveness of each ad. Previous research indicated that viewers who were asked to consider purchasing products in the ads looked at the text earlier and more often than the picture part of the ad. In contrast, viewers in the present experiment looked at the picture part of the ad earlier and longer than the text. The results indicate quite clearly that the goal of the viewer very much influences where (and for how long) viewers look at different parts of ads, but also indicate that the nature of the ad per se matters.

Finding the right case: the role of predictive features in memory for aviation accidents

Three experiments examined the role of story structure in memory for written aviation accident reports by both pilots and nonpilots. Accident reports follow a standard format providing setting, complication, decision and outcome information. Following the ‘predictive features’ model, it was hypothesized that expertise would facilitate recall, and that pilots would recall most effectively with the complication feature. Pilot and nonpilot participants read and recalled 4 (Experiment 1) or 8 (Experiment 2) accident reports. With four cases, pilots recalled more than nonpilots, but no difference was found with eight cases. A primacy effect for pattern of recall was found in Experiment 1 with the setting and complication features most effective in triggering case recall. When task difficulty was increased (Experiment 2), the complication feature alone was the most effective. In Experiment 3, we manipulated text structure and found that complication and decision features were better recognized than setting or outcome features by nonpilots. The finding across three studies that the complication feature was consistently the most effective for retrieving aviation accident reports supports the ‘predictive features’ model.

The latent structure of anxiety sensitivity--revisited

Anxiety sensitivity has been implicated as a risk factor for the development and maintenance of panic and other anxiety disorders. Although researchers have generally assumed that anxiety sensitivity is a dimensional, rather than categorical, variable, recent taxometric research has raised questions concerning the accuracy of this assumption. The present study examined the latent structure of anxiety sensitivity by applying four taxometric procedures (MAXEIG, MAXCOV, MAMBAC, and L-Mode) to data collected from two large nonclinical samples (n = 1,025 and n = 744) using two distinct measures of anxiety sensitivity (Anxiety Sensitivity Profile and Anxiety Sensitivity Index-Revised). In contrast to previous taxometric analyses of anxiety sensitivity, results of the present research provided convergent evidence for a latent anxiety sensitivity dimension. Several potential explanations for the discrepancy between these findings and those of previous research are discussed, as well as the implications of these findings for the conceptualization and measurement of anxiety sensitivity.     

Predictors of Morale in U.S. Peacekeepers1

In this prospective study, we examined pre‐ and postmission predictors of morale in U.S. military peacekeepers deployed to Kosovo. After controlling for demographic and military characteristics, current general life stressors, unit cohesion, and reports of patriotism and nationalism were predictive of predeployment morale. We also found that positive military experiences, general overseas military stressors, and postdeployment unit cohesion were significant predictors of postdeployment morale after controlling for demographic and military characteristics and predeployment morale, cohesion, and patriotism/nationalism. The results suggest the need to broaden our understanding of the factors that may assist and motivate soldiers during demanding peacekeeping operations and the factors that may mitigate the impact of stressful demands and associated mission‐related strain.     

What lies beneath: Parenting style and implicit self-esteem

The current studies extend previous research on self-esteem by examining one of the likely origins of implicit self-esteem. Three studies showed that young adult children who reported that their parents were more nurturing reported higher implicit self-esteem compared with those whose parents were less nurturing. Studies 2 and 3 added a measure of overprotectiveness and revealed that children who reported that their parents were overprotective also reported lower implicit self-esteem. Moreover, Study 3 revealed that mothers’ independent reports of their early interactions with their children were also related to children’s level of implicit self-esteem. In all three studies, these findings remained reliable when we controlled statistically for participants’ explicit self-esteem. These findings contribute to a growing body of literature validating the construct of implicit self-esteem.     

Finger flexor motor control patterns during active flexion: an in vivo tendon force study

An in vivo tendon force measurement system was used to evaluate index finger flexor motor control patterns during active finger flexion. During open carpal tunnel release surgery (N=12) the flexor digitorum profundus (FDP) and flexor digitorum superficilias (FDS) tendons were instrumented with buckle force transducers and participants performed finger flexion at two different wrist angles (0 degrees or 30 degrees ). During finger flexion, there was concurrent change of metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joint angles, but the FDP and FDS tendon force changes were not concurrent. For the FDS tendon, no consistent changes in force were observed across participants at either wrist angle. For the FDP tendon, there were two force patterns. With the wrist in a neutral posture, the movement was initiated without force from the finger flexors, and further flexion (after the first 0.5s) was carried out with force from the FDP. With the wrist in a flexed posture, the motion was generally both initiated and continued using FDP force. At some wrist postures, finger flexion was initiated by passive forces which were replaced by FDP force to complete the motion.
