Screening for disinhibited disorder cases in a college population: Performance of the SMAST, DAST, SCID-II-Q, and PDQ-4.
Psychiatric disorders characterized by disinhibition--substance use disorders, antisocial personality disorder (PD), and borderline PD--represent a serious risk to the safety and health of college students. The ability of researchers and clinicians to identify students most at risk for disinhibited disorders associated with campus crime, violence, and self-harm depends on measures with strong evidence of diagnostic efficiency, yet data on the diagnostic efficiency of screening measures in college populations are lacking. The authors addressed this need by examining the diagnostic efficiency of commonly used screening measures for disinhibited disorders in a sample of 2,085 students, 79 of whom also completed diagnostic interviews. Results suggest that the diagnostic efficiency (e.g., sensitivity, specificity) of screening measures for substance use disorders and antisocial PD in college samples can be increased by making simple adjustments in screening cutoff criteria. Similar adjustments did not increase the diagnostic efficiency of the screening measure for borderline PD, and this suggested that certain screeners may best be aimed at ruling out disorders. This type of information offers users flexibility with which to tailor the screening threshold to serve different objectives.

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.

A behavioral genetic analysis of the relationship between the socialization scale and self-reported delinquency.
This investigation examined the genetic (A), and shared (C) and nonshared (E) environmental variance contributions to the relationship of self-reported delinquency (as measured by the "Delinquent Behavior Inventory" [DBI; Gibson, 1967]) to the Socialization (So) scale of the California Psychological Inventory using univariate and bivariate structural equation models. The scales were administered to 222 male (145 monozygotic; 77 dizygotic) and 159 female (107 monozygotic; 52 dizygotic) 16- to 18-year-old same-sex twin pairs. Principal components analysis with varimax rotation revealed three interpretable So factors representing family/home environment, self-concept, and behavioral control. Univariate modeling suggested sex differences in etiological influences associated with individual differences in most scales. The bivariate ACE model fit the data, suggesting that the covariance between the So scale and self-reported delinquency owes in part to shared etiological factors.

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.

Personality trait differences in boys and girls with clinical or sub-clinical diagnoses of conduct disorder versus antisocial personality disorder.
This study tested differences in personality traits measured by the Multidimensional Personality Questionnaire (MPQ) in a community sample of adolescents with definite or probable conduct disorder (CD) diagnoses that did not progress to a diagnosis of antisocial personality disorder (ASPD) by early adulthood (n=43), those with definite or probable ASPD that persisted into early adulthood (n=68), or controls with neither a CD nor an ASPD diagnosis (n=716) to examine whether antisocial behaviour disorders that differed in course were associated with differences in personality traits. As expected, boys and girls with ASPD were significantly different from controls on constraint, and those with ASPD were significantly lower on constraint than those with only CD. The results suggest that individual differences in certain personality traits may contribute to differences in the type of antisocial behaviour disorder that emerges and thereby to the course of antisocial behaviour.

Antisocial behavior, substance use, and somatization in families of adolescent drug abusers and adolescent controls.
Symptoms of conduct disorder (CD), antisocial personality disorder (ASP), alcohol abuse, drug abuse, and somatization were tabulated for the families of 35 delinquent, substance-abusing (multiple-problem) adolescent male probands and 35 age-matched control males. Alcohol abuse, CD/ASP, and somatization were assessed with either the Diagnostic Interview Schedule (DIS) (for participants aged 18 and up) or the Diagnostic Interview for Children and Adolescents (DICA) (for participants aged 12 to 17). Drug abuse for all participants was assessed with the Substance Abuse Module (SAM) of the Comprehensive Interview for Diagnostic Evaluation (CIDE). As expected, proband groups had significantly more (p < .0001) CD/ASP, alcohol abuse, and drug abuse symptoms than control groups. A significant (p < .01) positive correlation among CD/ASP, alcohol abuse, and drug abuse was found for each group. Somatization was not differentially associated with proband status. It was concluded that identifying male multiple-problem youths also identifies families with a high incidence of similar problems.

Community participation in organising rural general practice: is it sustainable?
OBJECTIVE
We analysed community participation in organising rural general medical practice in order to suggest ways to extend and sustain it.


DESIGN
A multisite, embedded case-study design collecting data through semistructured interviews, non-participation observation and a document analysis.


SETTING
One remote and two rural communities in Australia.


PARTICIPANTS
Community members, GPs, health professionals, government officers and rural medical workforce consultants.


RESULTS
High levels of community participation in recruiting and retaining GPs, organising the business model, and contributing to practice infrastructure were evident. Community participation in designing health care was uncommon. Participation was primarily to ensure viable general practice services necessary to strengthen the social and economic fabric of the community. There were factors about the decision-making and partnership processes in each of the communities that threatened the viability of community participation.


CONCLUSIONS
We recommend that a concept of community development and explicit facilitation of the processes involved is necessary to strengthen participation, create effective partnerships and ensure inclusive decision-making.

A summary of the theory of velocity selective neural recording
This paper describes improvements to the technique of velocity selective recording (VSR) in which multiple neural signals are matched and summed to identify excited axon populations in terms of velocity. This form of recording has been termed intrinsic velocity selective recording (IVSR). The signals are acquired using a multi-electrode cuff (MEC) which is now available as a component for use in implantable neuroprostheses. The improvements outlined in the paper involve the use of bandpass filters at the output of the system which allows a higher level of selectivity to be obtained than is possible using IVSR.

The rhetoric vs. the reality in child care and protection: ideology and practice in working with fathers.
Within child care and protection, practitioners can be paralysed by a fundamental gap between the rhetoric and the reality in engaging fathers in their children's care. In an earlier paper we argued that there is a lack of an effective framework to guide practice with fathers in child care and protection work. We examined how health visitors and social workers could begin to assess how fathers could be categorized as either (or both) a risk or an asset to the child. Based on a review of the literature we now explore the limitations of current models of practice and trace the theoretical strands that influence them, drawing from the legal framework, attachment theory and models for anti-oppressive practice. We then highlight messages for practice with fathers for health care professionals involved in child protection. The working context for this paper is Scotland, although we believe that the ideas may be extrapolated to other geographical areas.

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.

Predicting child abuse and neglect: ethical, theoretical and methodological challenges.
AIMS
This paper explores the ethical, theoretical and methodological implications of predictive testing in studies of child abuse, neglect and harm.


BACKGROUND
The use of screening instruments to make predictions about children who may later be abused, neglected or at risk of exclusion is promoted in research and policy. The recent UK Action Plan on Social Exclusion suggests that health visitors and community midwives should be trained to use these tools in practice.


METHOD
Position paper.


CONCLUSIONS
The accuracy of screening instruments to identify children who will be abused or neglected has not been established. Even if the theoretical and methodological challenges of predictive instruments could be overcome, the ethical implications of their use are very difficult for nurses and midwives.


RELEVANCE TO CLINICAL PRACTICE
Nurses, midwives and health visitors require high levels of awareness of risk factors in working with children and families. We have a responsibility to reach professional judgements about risks of harm for individuals. This is best performed through improving skills in working with parents and carers to identify those factors which may impede their ability to offer safe developmental care to their children.
