Determining the focus of driving fears.
Fear of driving has been recognized as a complex diagnostic entity. Studies on flying phobia have drawn similar conclusions, although increasing clarity has been gained through research that indicates that there may be subtypes of flying phobia based on the focus of fear. However, it is unclear if similar subtypes exist for fear of driving. The aim of the present study was to conduct a preliminary investigation of driving fear subtypes and to clarify further whether there were differences between driving-fearful respondents who had been in a motor vehicle accident (MVA) and those who had not. Eighty-five driving-fearful, media-recruited respondents completed a questionnaire that assessed anxiety, avoidance, and concerns related to their driving fears. The sample had high expectations of negative events while driving. There were no significant differences between those who had experienced an MVA and those who had not on various measures of fear severity. Cluster analysis revealed two main foci of fear, one characterized by danger expectancies and the other based on anxiety expectancies and unpleasant driving situations. This emphasizes the importance of assessing both internal and external foci of fear. Although this finding is consistent with the results obtained for flying phobia, more research is required to replicate and extend these results and to develop and evaluate differential treatment programs.

Comparison and characteristics of motor vehicle accident (MVA) and non-MVA driving fears.
Prior research has revealed the diagnostic complexity among people who report driving fears. However, the focus on survivors of motor vehicle accidents (MVAs) and diagnostic samples may have inadvertently led to a relative neglect of the broader driving-fearful population. No studies could be located that compared MVA survivors with those who had not experienced an MVA. The aim of the present study was to address these deficits by comparing the characteristics of MVA and non-MVA driving-fearfuls and also exploring a range of characteristics associated with driving fears. One hundred and ninety media-recruited driving-fearfuls completed a questionnaire that assessed severity of anxiety and avoidance associated with a variety of driving situations. It was found that fear levels were similar to samples of driving phobics and MVA victims. There were no significant differences between MVA and non-MVA respondents on various measures of fear severity. In addition, the sample rated a high level of anxiety when driving with someone who criticizes their driving. Implications of the findings are discussed, along with suggestions for assessment and treatment of those with driving-related fears.

What does the Driving and Riding Avoidance Scale (DRAS) measure?
Driving anxiety can have a significant impact on everyday functioning and usually results in some kind of avoidance behaviour. The Driving and Riding Avoidance Scale (DRAS; Stewart, A. E., & St. Peter, C. C. (2004). Driving and riding avoidance following motor vehicle crashes in a non-clinical sample: psychometric properties of a new measure. Behaviour Research and Therapy, 42, 859-879) shows promise in the self-report assessment of the degree of such avoidance. The present study investigated the psychometric properties of the DRAS in a sample of 301 university students. Internal consistency for the DRAS was 0.89 and temporal stability over two months was 0.71. The factor structure of the DRAS supported the use of the general and traffic avoidance subscales but not the weather and riding avoidance subscales in the present non-clinical sample. However, a significant limitation of the DRAS is that it does not assess the reasons for driving avoidance, and is therefore not a measure of avoidance that is due to driving anxiety. Some items may be rated highly for practical reasons, such as avoidance because of increasing fuel and other costs associated with driving. Modified instructions for the DRAS should ensure that it measures anxiety-related avoidance behaviour.

Acquisition and severity of driving-related fears.
Rachman's theory of fear acquisition proposes that directly-conditioned fears will differ from indirectly-conditioned fears in magnitude and anxiety response patterns, however the theory has received inconsistent empirical support. The aim of the present study was to describe the fear acquisition pathways for a community sample who reported driving-related fears, and to test Rachman's theory of fear acquisition. One hundred and ninety participants completed a questionnaire which assessed a variety of driving-related situations, reactions to motor vehicle accidents (MVAs), and anxiety response patterns. Professional psychological helpseeking and perceived need for treatment for driving-related fears were also assessed. Results failed to support Rachman's predictions. However, it was confirmed that respondents who had been involved in an MVA were more likely to ascribe their fears to a directly-conditioned pathway. The theoretical and methodological implications of the findings are discussed, along with suggestions for assessment of those with driving-related fears.

A meta-analysis of the effects of psychotherapy with adults sexually abused in childhood.
This paper presents the results of a meta-analysis of the treatment outcome studies of different types of psychotherapeutic approaches for adults sexually abused as children. There were 44 studies included comprising 59 treatment conditions, and most of the studies aimed to treat the psychological effects of childhood sexual abuse. Separate meta-analyses were conducted according to study design and outcome domain, in keeping with meta-analytic conventions. For most outcome domains, there was remarkable consistency in overall effect sizes across study design. Effect sizes were predominantly of moderate magnitude for post-traumatic stress disorder or trauma symptoms (g=0.72-0.77), internalizing symptoms (g=0.68-0.72), externalizing symptoms (g=0.41-0.53), self-esteem (g=0.56-0.58), and global functioning or symptoms (g=0.57-0.60). Studies measuring interpersonal functioning outcomes had inconsistent effect sizes across study design. Effects were largely maintained at follow-up, although relatively few studies provided follow-up data. A number of moderating variables were examined given the inherent heterogeneity of the studies. Moderator analysis revealed a variety of variables, particularly treatment characteristics, that were associated with better outcomes. However, different variables were identified for the diverse outcomes that were measured, emphasizing the importance of moderator analysis in looking beyond overall treatment effects to ascertain specific elements that confer additional benefit in therapy for the diverse psychological effects of child sexual abuse.

Driving fear and driving skills: comparison between fearful and control samples using standardised on-road assessment.
The present study explores driving skills in a group of 50 media-recruited driving-fearful and 50 control drivers, all of whom were women. Participants completed an on-road practical driving assessment with a professional driving instructor. Diagnostic as well as pre-post self-report and instructor driving assessments were conducted. Fearful drivers made more errors on the driving assessment than controls. However, the pattern of errors was identical for both groups, indicating that fear and anxiety may be associated with the number rather than the type of driving errors made. These differences remained when factors such as driving history, current driving frequency, and diagnosis were controlled using case selection. More research is needed to replicate the findings in more diverse samples. Additional work should also aim to clarify the specific role of driving skills in driving fear, which will facilitate treatment planning for exposure-based treatments and help identify cases where driving skills assessment may be appropriate.

Consumer expectations of nonprescription medications according to location of sale.
OBJECTIVE
To determine whether the public has different expectations of nonprescription medications based on location of sale.


DESIGN
Cross-sectional, descriptive.


SETTING
Saskatoon, Saskatchewan, Canada, during the summer of 2003.


PARTICIPANTS
2,102 randomly selected citizens.


INTERVENTION
Mail survey.


MAIN OUTCOME MEASURES
Differences in expectations for potency, safety, adverse effects, effectiveness, and package information of products sold in pharmacies versus convenience stores.


RESULTS
The response rate was 57.2%. Most participants (81.2%) were aware that nonprescription medications could be purchased in convenience stores, but far fewer (42.3%) had done so. As one potential resource during purchases, pharmacists were held in reasonably high regard. Expectations with the greatest difference were of a merchandising nature. Respondents expected pharmacies to have a better quality and selection of products and lower prices. For drug-related attributes, differences were minimal but statistically significant.


CONCLUSION
Location of sale does not appear to have any practical influence on consumer expectations of the drug-related attributes of nonprescription medications. Buyers of such products expect similar properties to be present regardless of location.

Heritability of Wisconsin Card Sorting Test (WCST) and Stroop Color-Word Test performance in normal individuals: implications for the search for endophenotypes.
A surge in the search for endophenotypes for psychiatric disorders has occurred in the past several years. An important criterion of an endophenotype is that it is heritable. Two of the most widely used executive cognitive functioning measures are the Wisconsin Card Sorting Test (WCST) and the Stroop Color-Word Test. Each has been considered as a possible endophenotype. However, research on the heritability of each of these measures is sparse, and in the case of the WCST, mixed. As part of a pilot twin study examining cognitive functioning and personality in adults, the WCST and the Stroop were administered to 80 monozygotic and 29 dizygotic twin pairs screened for absence of neurological disease and head injury. Results replicated and extended previous findings for moderate heritability of Stroop performance. However, the WCST showed little evidence of genetic influence, suggesting that it might not meet one of the criteria for an endophenotype.

The theory of velocity selective neural recording: a study based on simulation
This paper describes the improvements to the theory of velocity selective recording and some simulation results. In this method, activity in different groups of axons is discriminated by their propagation velocity. A multi-electrode cuff and an array of amplifiers produce multiple neural signals; if artificial delays are inserted and the signals are added, the activity in axons of the matched velocity are emphasized. We call this intrinsic velocity selective recording. However, simulation shows that interpreting the time signals is then not straight-forward and the selectivity Qv is low. New theory shows that bandpass filters improve the selectivity and explains why this is true in the time domain. A simulation study investigates the limits on the available velocity selectivity both with and without additive noise and with reasonable sampling rates and analogue-to-digital conversion parameters. Bandpass filters can improve the selectivity by factors up to 7 but this depends on the speed of the action potential and the signal-to-noise ratio.

Strong and weak male mutation bias at different sites in the primate genomes: insights from the human-chimpanzee comparison.
Male mutation bias is a higher mutation rate in males than in females thought to result from the greater number of germ line cell divisions in males. If errors in DNA replication cause most mutations, then the magnitude of male mutation bias, measured as the male-to-female mutation rate ratio (alpha), should reflect the relative excess of male versus female germ line cell divisions. Evolutionary rates averaged among all sites in a sequence and compared between mammalian sex chromosomes were shown to be indeed higher in males than in females. However, it is presently unknown whether individual classes of substitutions exhibit such bias. To address this issue, we investigated male mutation bias separately at non-CpG and CpG sites using human-chimpanzee whole-genome alignments. We observed strong male mutation bias at non-CpG sites: alpha in the X-autosome comparison was approximately 6-7, which was similar to the male-to-female ratio in the number of germ line cell divisions. In contrast, mutations at CpG sites exhibited weak male mutation bias: alpha in the X-autosome comparison was only approximately 2-3. This is consistent with the methylation-induced and replication-independent mechanism of CpG transitions, which constitute the majority of mutations at CpG sites. Interestingly, our study also indicated weak male mutation bias for transversions at CpG sites, implying a spontaneous mechanism largely not associated with replication. Male mutation bias was equally strong at CpG and non-CpG sites located within unmethylated "CpG islands," suggesting the replication-dependent origin of these mutations. Thus, we found that the strength of male mutation bias is nonuniform in the primate genomes. Importantly, we discovered that male mutation bias depends on the proportion of CpG sites in the loci compared. This might explain the differences in the magnitude of primate male mutation bias observed among studies.

Practitioner assessments of 'good enough' parenting: factorial survey.
AIM
The aim of this study was to measure health visitors' professional judgements on 'good enough' parenting and identify what factors and combinations of these are important when making such judgements.


BACKGROUND
The relationship between parenting and child health is unclear. Whilst agreement exists that 'good enough' parenting requires boundary setting, consistency and putting the child's needs first, attempting to define 'good enough' parenting in precise terms is complex. When faced with a complex situation, practitioners rely on relatively few factors to form judgements.


DESIGN
Factorial survey methods were employed using vignette techniques.


METHODS
Vignettes were constructed using previous research on those variables, which may influence nurses' judgements, for example, accommodation and child dentition. The level of factors was randomly varied. Two thousand vignettes were administered to a sample of 200 health visitors in two Health Boards who then made a judgement about this scenario.


ANALYSIS
Data were analysed through multiple regression with dummy variables and one-way analysis of variance. Regression equations for both good enough mothering and good enough parenting are reported.


RESULTS
The models used are significant predictors of parenting and mothering. Significant predictors on health visitor judgements' were boundary setting in sleep behaviours, type of housing inhabited and health behaviours. Although parenting and mothering are often conflated, health visitors appear to separate these aspects when making judgements based on type of housing.


CONCLUSIONS
Most professionals can articulate what makes a 'good' parent, equally they may have strong views regarding what constitutes 'poor' parenting. The difficulty is in determining when parenting is 'good enough' to provide a child with a nurturing environment.


RELEVANCE TO CLINICAL PRACTICE
This study suggests that practitioners move their thresholds of what is 'good enough' depending on a narrow range of factors. Awareness of the factors, which influence individuals' judgements is important in safeguarding children.
