The Florida State Twin Registry: research aims and design.
Relatively little is known about the relationship of most personality disorders to executive cognitive functioning despite their associations with frontal cortex activity. Research on genetic influence is lacking for most personality disorders, and research on genetic influences associated with executive cognitive functioning is sparse and mixed. The Florida State Twin Registry was created to conduct a pilot twin study aimed at examining genetic influence on personality disorders and executive cognitive functioning. Measures included structured clinical interviews for symptoms and diagnoses of personality disorders (borderline, histrionic, narcissistic, antisocial, obsessive-compulsive, avoidant, and dependent), depression, substance abuse/dependence, anxiety disorders, and eating disorders. The Wisconsin Card Sorting Test and the Stroop Color-Word Test were administered to assess executive cognitive functioning. Self-report questionnaires were included to assess maladaptive personality traits. Data sharing and future directions for growing the Florida State Twin Registry are discussed.

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.

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.

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.

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.

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.

Development of a short form of the Test Anxiety Inventory (TAI).
The Test Anxiety Inventory (TAI) is widely used in research and practical settings and has particular application to the assessment and treatment of test anxiety in student populations. However, there are a number of instances in which a short version of the TAI would be more appropriate, especially when time constraints preclude the use of the full form. Similar short forms have been developed for other measures such as the State scale of the State-Trait Anxiety Inventory (STAI; T. M. Marteau & H. Bekker, 1992). The authors of the present study aimed to develop a short form of the TAI. The TAI was completed by 333 undergraduate psychology students. Item-remainder correlations were used to compare short forms with varying numbers of items. Internal consistency and concurrent and construct validity were assessed in hypothetical and actual examination conditions. A 5-item short form produced optimal reliability and validity, and a balance of items from the Worry and Emotionality subscales of the TAI. Further research is needed to replicate these results, but the 5-item short form of the TAI shows promise, particularly for contexts in which time demands preclude the use of longer versions.

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.

Protein biofortified sorghum: effect of processing into traditional african foods on their protein quality.
Protein biofortification into crops is a means to combat childhood protein-energy malnutrition (PEM) in developing countries, by increasing the bioavailability of protein in staple plant foods and ensuring sustainability of the crop. Protein biofortification of sorghum has been achieved by both chemically induced mutation and genetic engineering. For this biofortification to be effective, the improved protein quality in the grain must be retained when it is processed into staple African foods. Suppression of kafirin synthesis by genetic engineering appeared to be superior to improved protein digestibility by chemical mutagenesis, because both the lysine content and protein digestibility were substantially improved and maintained in a range of African foods. For the genetically engineered sorghums, the protein digestibility corrected amino acid score was almost twice that of their null controls and considerably higher than the high protein digestibility sorghum type. Such protein biofortified sorghum has considerable potential to alleviate PEM.

Cough and cold medication use in young children: Pharmacist reaction to changes in Canada.
OBJECTIVE
To gauge how community pharmacists will approach questions from the public after Canada begins requiring product labels to state that cough and cold medications should not be used in children younger than 6 years of age.


DESIGN
Cross-sectional study.


SETTING
Province of Saskatchewan, Canada, in February 2009.


PARTICIPANTS
143 community pharmacists.


INTERVENTION
Questionnaire was faxed to target group.


MAIN OUTCOME MEASURES
Estimates of product use in children aged 2 years to younger than 6 years, pharmacist satisfaction with the new guidelines, and potential plans when the new labels reach the market.


RESULTS
143 pharmacists returned a completed questionnaire by fax. Pharmacists currently recommend products for head colds for children aged 2 years to younger than 6 years more often than antitussives for coughs. More pharmacists were dissatisfied with the new ruling compared with those who were satisfied, with a main concern being that it went too far. Respondents indicated that when the new labels are implemented, they would be more likely to recommend use of the products among close family members than among the public.


CONCLUSION
These results suggest some support for product efficacy but possible concern over potential liability. Pharmacists are also concerned that removing dosing guidelines from packaging may not fully deter parental use of such products.

The impact of manual handling on nursing home resident mobility during transfers on and off furniture: a systematic review.
This systematic review aimed to investigate the impact of staff manual handling practices and physical training interventions on nursing home residents' ability to transfer on and off furniture. Key words and subject headings were used to search databases for English language studies published after 1994. Ten studies met the inclusion criteria. Studies of physical activity interventions indicated that physical activity training will benefit residents' transfer ability. One study examined the effect of a safe manual handling program on resident quality care outcomes. Further research is required into the nature and impact of the assistance provided by staff to residents during transfers. Innovative and sustainable approaches to safe manual handling that promote resident mobility are needed.
