Differential effects of safety behaviour subtypes in social anxiety disorder

Clinical observations indicate that individuals with Social Anxiety Disorder (SAD) use a variety of safety behaviours; however, virtually no research has examined the functional effect of different safety-seeking strategies. Accordingly, we conducted two studies to address this issue. Study 1 measured global patterns of safety behaviour use in a large analogue sample. Factor analysis revealed two primary safety behaviour categories, avoidance and impression management. Study 2 assessed situational use of safety behaviours during a controlled social interaction in a clinical sample of 93 patients with Generalised SAD. Factor analysis again revealed support for avoidance and impression-management subtypes. Notably, the two types of safety behaviours were associated with different social outcomes. Avoidance safety behaviours were associated with higher state anxiety during the interaction and negative reactions from participants’ interaction partners. Impression-management strategies appeared to impede corrections in negative predictions about subsequent interactions. These findings suggest that it may be beneficial to consider the unique effects of different safety-seeking strategies when assessing and treating SAD.     

Sequential dependencies in driving

The effect of recent experience on current behavior has been studied extensively in simple laboratory tasks. We explore the nature of sequential effects in the more naturalistic setting of automobile driving. Driving is a safety-critical task in which delayed response times may have severe consequences. Using a realistic driving simulator, we find significant sequential effects in pedal-press response times that depend on the history of recent stimuli and responses. Response times are slowed up to 100 ms in particular cases, a delay that has dangerous practical consequences. Further, we observe a significant number of history-related pedal misapplications, which have recently been noted as a cause for concern in the automotive safety community. By anticipating these consequences of sequential context, driver assistance systems could mitigate the effects of performance degradations and thus critically improve driver safety.     

Development of a pleasure in parenting scale

Two major components of parenting have been identified: warmth and control. There has been a great deal of work on the measurement of control, but there are not many measures of parental warmth. As part of an attempt to develop better measures of warmth, we developed a scale measuring parents' pleasure in carrying out routine caretaking acts with their children. This measure was then related to other measures of positive support such as observation, observer ratings and questionnaires. As there is evidence in the literature that quality of the environment interacts with parenting, we related the measure to measures of stress, observer ratings of quality of the home, marital interaction and parental mood. Finally, we examined the relation of child variables (attachment classification, temperament rating and observed behaviours) to the parents' ratings of pleasure in the child.     

Personality traits and health‐risk behaviours in university students

Relations between personality and health‐risk behaviours in university undergraduates were examined using multiple measures of personality across multiple samples (N = 1151). Big Five personality variables, at both factor and facet levels, were used to predict three specific health‐risk behaviours: (a) tobacco consumption, (b) alcohol consumption and (c) speeding in an automobile. Our findings showed that low Conscientiousness and low Agreeableness were uniformly associated with this cluster of potentially health damaging behaviours. Extraversion was additionally associated with alcohol use. Interaction effects were found between Conscientiousness and Agreeableness on smoking and (for men only) on drinking. Other personality variables not centrally related to the Big Five, such as Risk‐Taking (high) and Integrity (low), were also implicated in the present health‐risk behaviours.

Belief disconfirmation versus habituation approaches to situational exposure in panic disorder with agoraphobia: a pilot study

Exposure therapy and cognitive behaviour therapy (CBT) are both effective in the treatment of panic disorder with agoraphobia. Cognitive theories suggest that the way in which exposure to avoided situations is implemented in either treatment may be crucial. In particular, it is suggested that clinical improvement will be greatest if opportunities for disconfirmation of feared catastrophes are maximized. In a small pilot study, 16 patients with panic disorder and (moderate or severe) agoraphobia were randomly allocated to either habituation based exposure therapy (HBET) or exposure planned as a belief disconfirmation strategy and accompanied by dropping of safety-seeking behaviours. Both treatments were brief (total of 3.25 h of exposure) and were similar in terms of expectancy of change. Patients in the CBT condition showed significantly greater improvements in self-report measures of anxiety, panic and situational avoidance. They also completed significantly more steps in a standardized behavioural walk, during which they experienced significantly less anxiety. The controlled effect sizes for CBT were substantial (range 1.7-2.7), which suggests it may be a particularly efficient way of managing therapeutic exposure to feared situations in panic disorder with agoraphobia. Further research is needed to clarify the mechanism of change involved.     

REPLY TO JULIA DRIVER,TIMM TRIPLETT,AND KATHLEEN WALLACE

Abstract: Julia Driver, Timm Triplett, and Kathleen Wallace challenge my account of moral arrogance, and Triplett and Wallace challenge its application to the problem of abortion. I try to show here that Driver's attempt to defend consequentialism from my charge that it promotes moral arrogance is successful only if consequentialism explicitly gives up what has been considered one of its major virtues. I acknowledge that Triplett has uncovered some unclarity in my claim that the moral acceptability of abortion is an unresolvable moral issue. I also acknowledge that Wallace has uncovered some unclarity in my account of moral arrogance. After clarifying that account, I try to meet her challenge to defend my claim that it is not morally arrogant for a state to place some restrictions on abortions.     

Gender and health behaviours of hypertensive patients: mediating role of control beliefs

Previous studies have reported gender differences in patients’ health behaviours but few studied hypertensive patients. The potential underlying factors that may mediate gender influences on health behaviours is also a more critical area worthy of investigation. This study examined health locus of control (HLC) as a pathway of gender effects on health behaviours of hypertensive patients. The Multidimensional HLC Scale (Form C) and Wellness behaviour subscale of Health Behaviour Checklist were completed by 400 hypertensive outpatients in two Nigerian hospitals: Enugu State University Teaching Hospital, Park Lane, Enugu, and Bishop Shanahan Specialist Hospital, Nsukka. Hierarchical multiple regression results showed that gender significantly predicted health behaviours. Gender also significantly predicted internal HLC, chance HLC, and other people HLC, but did not predict doctor HLC. The association between gender and health behaviours was fully mediated by internal HLC, chance HLC and other people HLC. Understanding the explanatory mechanisms linking socio-demographic factors and health behaviours is considered of great importance for future research and healthcare intervention.     

Risk profiles in novice road users: Relation between moped riding simulator performance,on-road aberrant behaviors and dangerous driving

The aim of this study was to compare the scores obtained by an Italian sample of novice drivers/riders on an adapted version of the Driver Behaviour Questionnaire (DBQ) and the Dula Dangerous Driving Index (DDDI) with their performance in a moped-riding simulator. Cluster analysis on the indexes extracted by the simulator were used to identify two groups with opposite riding styles: Prudent riders and Imprudent riders.Using the DBQ, our data not only confirmed data in the literature indicating that females reported more driving Errors than males, and that males reported higher Intended Violation scores than females, but also showed that gender effects are modulated by riding style (as measured by the simulator) and driving exposure. Differences between males’ and females’ DBQ scores were only apparent for Imprudent riders, while the reported Errors, Slips and Lapses, and Violations were lower the higher the driving exposure.As for the DDDI, males scored higher than females for Risky Driving, and the Aggressive Driving scores were higher the greater the driving exposure, but only for Imprudent riders.These results provide crucial information for the use of DBQ and DDDI questionnaires in the Italian population. They also confirm that a multidimensional approach, supported by the use of driving simulators, may facilitate a more detailed assessment of riding abilities.
