Substance Use Disorders and Cluster B Personality Disorders: Physiological, Cognitive, and Environmental Correlates in a College Sample
Substance use disorders (SUDs) and Cluster B personality disorders (PDs) are both marked by impulsivity and poor behavioral control and may result in part from shared neurobiological or executive cognitive functioning deficits. To examine the potential utility of such models in explaining variance in SUDs and PDs at the lower end of symptom expression and impairment, 123 (73 female) volunteer college students were administered 2 measures of executive cognitive functioning; a task assessing autonomic reactivity to aversive noise blasts; a life events and a peer substance use measure; and structured clinical interviews to assess symptoms of substance abuse/dependence and antisocial, borderline, histrionic, and narcissistic PDs. As expected, symptoms of SUDs and PDs were significantly positively correlated. Antisocial PD, alcohol and cannabis use disorder symptoms were significantly positively related to proportion of friends who use alcohol and drugs regularly and drug use among romantic partners. Number of negative life events was positively related to PD symptoms and to alcohol use disorder symptoms. Executive cognitive functioning was not related to SUD and PD symptoms in the expected direction. Findings suggest that, among higher functioning young adults, environmental factors may be particularly relevant to our understanding of SUDs and certain PDs.

Electrodermal reactivity and its association to substance use disorders.
Poor electrodermal response modulation is associated with substance use disorders, but the specificity of the relationship has not been tested. To test this, 112 college students were assessed for psychiatric symptoms using structured interviews and for ability to modulate skin conductance responses to 2-s 92- or 110-dB white noise blasts that varied in temporal predictability. Twenty-eight good and 28 poor modulators were compared on symptoms of alcohol and illicit drug use disorders, personality disorders (antisocial, borderline, histrionic, and narcissistic), social and specific phobia, and depression. As expected, poor modulators had significantly more symptoms of substance use disorders than good modulators. Groups did not differ in symptoms of anxiety disorder, depression, or personality disorders marked by disinhibition. Poor electrodermal response modulation may reflect a biological risk factor for substance use disorders in particular.

Sex differences, assortative mating, and cultural transmission effects on adolescent delinquency: a twin family study.
The twin study literature contains inconsistencies regarding both the estimates of genetic, shared, and nonshared environmental influence on delinquency and sex differences in the etiological influences on delinquency. Additionally, little is known about assortative mating and cultural transmission effects on delinquency. The present study was aimed at examining the etiology of delinquency in adolescence and examining assortative mating and transmission effects. To this end, we applied the social homogamy structural equation model to self-reported delinquency data from 486 families with 17-year-old male and female twins. We expected stronger shared environmental influences on delinquency among girls than boys and stronger environmental than genetic effects on adolescent delinquency in general. The results indicated nonsignificant sex differences in the estimates of genetic and environmental influences on delinquency. The best-fitting model suggested that 18 %, 56 %, and 26% of the variance in delinquency among both boys and girls is associated with additive genetic, nonshared environmental, and shared environmental factors, respectively. This finding was consistent with our expectation that environmental factors play an important role in adolescent delinquency. Parental cultural effects accounted for a small part of the transmission of delinquency within families while assortative mating was, in part, accounted for by cultural and social background factors. Future work should focus on identifying important environmental factors related to delinquency.

An update on the Florida State Twin Registry.
The Florida State Twin Registry began in 2002 through a pilot study of personality disorders and executive cognitive functioning in adult twins. Since 2006, the registry has grown substantially as part of the Learning Disability Research Center at Florida State University that recently began its second funding cycle through the National Institute of Child Health and Development. An update on the Florida State Twin Registry sample, focus, and measures is provided, as well as future directions.

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.

Driving anxiety and fear in young older adults in New Zealand.
BACKGROUND
driving anxiety and fear can have a marked impact on mobility and independence, although there is no data on the prevalence of this problem, and specific information about the rate of driving anxiety and fear in older adults is unknown.


METHODS
the present study examines the prevalence of self-reported driving anxiety and fear in a sample of 2,491 adults aged 55-72 from a longitudinal survey of health and ageing in New Zealand.


RESULTS
most of the sample (90%) described themselves as drivers who drove daily or weekly. Around 70% of the sample reported no driving anxiety or fear, yet 17-20% endorsed a mild and 4-6% rated a moderate to severe level of driving anxiety and fear. Women reported higher levels of anxiety and fear about driving than men, but there were no age differences. Those who reported some level of driving anxiety engaged various alternative modes of transport, and a small number (2.4%) reported that their driving anxiety had affected their usual activities or work for at least a day in the previous month. Duration of driving anxiety was highly variable, from relatively recent onset to being present for much of some participants' lifetimes.


CONCLUSION
driving anxiety and fear may be a significant problem for some young older adults that is likely to affect their independence and mobility. Further research to clarify the content and nature of driving anxiety, pathways to driving anxiety and the effect of factors associated with ageing on driving anxiety is needed in order to better understand this experience for older adults and develop effective interventions.

Children, health and gender: recognition in nursing research?
AIM
This paper examines the hitherto mostly unrecognised relationship between gender, health and children; its significance for nursing practice and how it has been considered in nursing research.


BACKGROUND
Holistic nursing practice with children requires adequate assessment and consideration of all potential influences on children's lives. Socioeconomic disparities have received widespread attention and gender inequalities in adult health have been studied in some depth. The links between gender, health and children, however, have received little consideration. The paper first considers this context in depth; it then applies the context to research in practice.


DESIGN
Systematic review.


METHODS
A systematic literature search was undertaken on four mainstream nursing research journals over 38 months up to February 2007. A total of 567 articles met the key word searches. Duplicates, opinion pieces and articles not focusing on children were removed. The remaining 23 nursing studies relevant to child health were examined for their gender sensitivity.


RESULTS
Full consideration of gender issues was found largely to be absent in nursing research on children. Eight studies gave specific consideration to gender relevance, where boys and girls may have responded differently to care. Only six studies specifically addressed gender sensitivity. Allowing children a voice, however, was a strength in these studies, with 18 reflecting children's views directly.


CONCLUSIONS
Major gaps still exist in research and theorisation relating to children, health and gender. These need to be acknowledged and investigated, particularly in relation to how they might impact on nursing care.


RELEVANCE TO CLINICAL PRACTICE
Nursing practice and research needs to account for all potential health issues, of which gender may often be important.

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.

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.
