RESUMO
This study examined the relationship between callous-unemotional (CU) traits and parenting practices over time in a mixed-sex community cohort (N = 1,008; 52.6% boys), aged 3 to 10 years (M = 6.5, SD = 1.3). Measures of CU traits, externalizing psychopathology, parenting practices, and socioeconomic risk factors were collected at baseline, and parenting practices and CU traits were reassessed at 12-month follow-up. CU traits uniquely accounted for change in three domains of parenting (inconsistent discipline, punishment, and parental involvement). Likewise, multiple domains of parenting (positive parenting, parental involvement, and poor monitoring/supervision) uniquely predicted change in CU traits. These seemingly bidirectional dynamics between CU traits and parenting were found to be largely moderated by child age and sex. Results partially replicate previous findings regarding the association between quality of parenting and prospective change in CU traits, and provide initial evidence that CU traits disrupt parenting practices over time.

AIM: Clinical practice improvement carried out in a quality assurance framework relies on routinely collected data using clinical indicators. Herein we describe the development, minimum training requirements, and inter-rater agreement of indicators that were used in an Australian multi-site evaluation of the effectiveness of early psychosis (EP) teams. METHODS: Surveys of clinician opinion and face-to-face consensus-building meetings were used to select and conceptually define indicators. Operationalization of definitions was achieved by iterative refinement until clinicians could be quickly trained to code indicators reliably. Calculation of percentage agreement with expert consensus coding was based on ratings of paper-based clinical vignettes embedded in a 2-h clinician training package. RESULTS: Consensually agreed upon conceptual definitions for seven clinical indicators judged most relevant to evaluating EP teams were operationalized for ease-of-training. Brief training enabled typical clinicians to code indicators with acceptable percentage agreement (60% to 86%). For indicators of suicide risk, psychosocial function, and family functioning this level of agreement was only possible with less precise 'broad range' expert consensus scores. Estimated kappa values indicated fair to good inter-rater reliability (kappa > 0.65). Inspection of contingency tables (coding category by health service) and modal scores across services suggested consistent, unbiased coding across services. CONCLUSIONS: Clinicians are able to agree upon what information is essential to routinely evaluate clinical practice. Simple indicators of this information can be designed and coding rules can be reliably applied to written vignettes after brief training. The real world feasibility of the indicators remains to be tested in field trials.

AIM: Expert opinion holds that the rate of implementation of specialist services for first presentation psychosis in Australia is much too slow. We aimed to collect evidence regarding this view from the first national survey of adult public mental health services about their self-reported efforts to implement specialist early psychosis intervention (EPI). METHODS: Using a purpose-designed Census form for assessing EPI implementation, adult public mental health service directors throughout Australia were asked about EPI-relevant local service activities. RESULTS: Sixty Census forms were returned (response rate = 61%), representing a total catchment population of 12.5 million people. A minority of services reported high levels of EPI implementation, which varied widely between area services and across state and territory jurisdictions. Rural and remote services were overrepresented in the lowest levels of reported EPI implementation. Only one service characteristic, the value of identifiable funding committed specifically to EPI, was predictive of level of reported EPI implementation. CONCLUSIONS: The disturbingly high levels of variability in EPI implementation across jurisdictions suggest a pressing need for a set of nationally agreed uniform EPI implementation standards. Additional specific strategies for rural and remote mental health services may be needed for these services to implement EPI.

The literature that is relevant to evaluation of treatment effectiveness is large, scattered and difficult to assemble for appraisal. This scoping review first develops a conceptual framework to help organize the field, and second, uses the framework to appraise early psychosis intervention (EPI) studies. Literature searches were used to identify representative study designs, which were then sorted according to evaluation approach. The groupings provided a conceptual framework upon which a map of the field could be drawn. Key words were cross-checked against definitions in dictionaries of scientific terms and the National Library of Medicine Medical Subject Headings (MeSH) browser. Using the final list of key words as search terms, the EPI evaluation literature was appraised. Experimental studies could be grouped into two classes: efficacy and effectiveness randomized controlled trials. Non-experimental studies could be subgrouped into at least four overlapping categories: clinical epidemiological; health service evaluations; quality assurance studies; and, quasi-experimental assessments of treatment effects. Applying this framework to appraise EPI studies indicated promising evidence for the effectiveness of EPI irrespective of study design type, and a clearer picture of where future evaluation efforts should be focused. Reliance on clinical trials alone will restrict the type of information that can inform clinical practice. There is convergent evidence for the benefits of specialized EPI service functions across a range of study designs. Greater investment in health services research and quality assurance approaches in evaluating EPI effectiveness should be made, which will involve scaling up of study sizes and development of an EPI programme fidelity rating template. The degree of complexity of the evaluation field suggests that greater focus on research methodology in the training of Australasian psychiatrists is urgently needed.

Self-injury without conscious suicidal intent is an increasingly prevalent phenomenon particularly among adolescent populations. This pilot study examined the extent and correlates of self-injurious behaviour in a school population sample of 393 adolescents (aged 13-18 years) using a self-report questionnaire. Specifically, we aimed to determine whether personality was related to self-injury and whether this relationship was moderated by emotion regulation or coping strategies. Few personality and coping variables were directly related to self-injury after controlling for age and psychopathology. However the relationship between personality and self-injury was moderated by coping skills and emotion regulation. We suggest future research explore these relationships in order to determine the role of coping skills and emotional regulation training in prevention of self-injury.

BACKGROUND: Psychopathy is characterised by profound deficits in the human tendency to feel and care about what other people feel, often known as 'affective empathy'. On the other hand, the psychopath often has intact 'cognitive' empathy skills, that is, he is able to describe what and why other people feel, even if he does not share or care about those feelings. Despite a rapidly advancing neuroscience of empathy, little is known about the developmental underpinnings of this psychopathic disconnect between affective and cognitive empathy. METHODS: The parents of N = 2760, 3-13-year-olds reported on the levels of empathy, callous-unemotional traits (CU), and antisocial behaviour (AB). Consistent with current theory and measurement practice, an index of 'psychopathic traits' was derived from the CU and AB measures. RESULTS: There are important gender and developmental differences in empathy deficits related to psychopathic traits. As expected, psychopathy is associated with severe deficits in affective empathy across all ages for males; however, no such deficits were found for females. Contrary to adult findings, psychopathic traits are associated with deficits in cognitive empathy in childhood for both sexes; however, males with high psychopathic traits appear to overcome these deficits in cognitive empathy as they move through the pubertal years. CONCLUSIONS: In contrast to cognitive empathy, low affective empathy does not appear to be associated with psychopathic traits in females. The characteristic disconnect between cognitive and affective empathy seen in adult male psychopathy crystallises in the pubertal years when they appear to learn to 'talk the talk' about other people's emotions, despite suffering severe deficits in their emotional connection (affective empathy) to others.

The construct of "empathy" embodies a number of characteristics necessary for psychological health in children. Surprisingly, most research has been based solely on children and adolescent report and observational measures despite evidence that multi-informant assessment is fundamental to the accurate measurement of such constructs. We present research documenting the development and validation of a brief parent-report measure of child empathy targeted at the formative years for the development of empathic skills, through to adolescence. The Griffith Empathy Measure, adapted from the Bryant Index of Empathy, showed convergence with child ratings, and good reliability and validity across gender and age. Consistent with theoretical accounts of empathy, it was found to include affective and cognitive components that showed divergent associations with other aspects of child functioning.

OBJECTIVE: To determine the incidence of equine herpesvirus-1 (EHV-1) infection among Thoroughbreds residing on a farm on which the virus was known to be endemic. DESIGN: Prospective cohort study. ANIMALS: 10 nonpregnant mares, 8 stallions, 16 weanlings, 11 racehorses, and 30 pregnant mares and their foals born during the 2006 foaling season. PROCEDURES: Blood and nasopharygeal swab samples were collected every 3 to 5 weeks for 9 months, and placenta and colostrum samples were collected at foaling. All samples were submitted for testing for EHV-1 DNA with a PCR assay. A type-specific EHV-1 ELISA was used to determine antibody titers in mares and foals at birth, 12 to 24 hours after birth, and every 3 to 5 weeks thereafter. RESULTS: Results of the PCR assay were positive for only 4 of the 1,330 samples collected (590 blood samples, 590 nasopharyngeal swab samples, 30 placentas, and 30 colostrum samples), with EHV-1 DNA detected in nasal secretions from 3 horses (pregnant mare, stallion, and racehorse) and in the placenta from 1 mare. Seroconversion was detected in 3 of 27 foals during the first month of life. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that there was a low prevalence of EHV-1 infection among this population of Thoroughbreds even though the virus was known to be endemic on the farm and that pregnant mares could become infected without aborting. Analysis of nasopharyngeal swab samples appeared to be more sensitive than analysis of blood samples for detection of EHV-1 DNA.

The aim of this study was to compare the outcomes associated with two differing right unilateral (RUL) electroconvulsive therapy (ECT) dosing protocols: 2-3X seizure threshold (2-3X ST) and fixed high dose (FHD) at 353 mC. A retrospective chart review was performed to compare patient outcomes during the implementation of two different dosing protocols: 2-3X ST from October 2000 to May 2001 and FHD from June 2001 to February 2002. A total of 56 patients received ECT under the 2-3X ST protocol, and 46 received ECT under the FHD protocol. In total, 13.6% of patients receiving ECT according to the 2-3X ST protocol received more than 12 ECT, whereas none of the FHD group received more than 12 ECT. The mean number of ECT per treatment course reduced significantly from 7.6 to 5.7 following the switch from the 2-3X ST protocol to the FHD protocol. There were no significant differences between the two groups in the incidence of adverse cognitive effects. ECT practitioners adhered to the 2-3X ST protocol for only 51.8% of ECT courses, with protocol adherence improving to 87% following introduction of the FHD protocol. Although this naturalistic retrospective chart survey had significant methodological limitations, it found that practitioners are more likely to correctly adhere to a fixed dose protocol, therefore, increasing its 'real world' effectiveness in comparison to titrated suprathreshold dosing techniques. The FHD protocol was associated with shorter courses of ECT than the 2-3X ST protocol, with no significant difference between the two protocols in clinically discernable adverse cognitive effects.

OBJECTIVE: To evaluate a hospital-based psychiatric consultation service for patients referred by general practitioners (GPs), and the effect on its use of a focused marketing strategy aimed at GPs. DESIGN AND SETTING: Postal survey of GPs in the catchment area (inner north Brisbane, Queensland), September to November 2003; and assessment of referrals, March to August 2003. MAIN OUTCOME MEASURES: Patient referrals, satisfaction among GPs who had referred, and awareness and opinions of the service among GPs who had not referred, compared with results of a similar survey conducted before marketing. RESULTS: In the 6 months after marketing, 43 patients were referred by 23 GPs, an average of 7.2 patients per month, compared with 2.5 per month in the first 12 months of the service. Survey responses were received from 13 of 36 GPs who had referred patients and 97 of 282 GPs who had not (response rate, 35%). Satisfaction among GPs who had referred remained high, and 12/13 felt the service should continue. Among GPs who had not referred, 76% were aware of the service, up from 26% in the previous survey, and 99% liked the concept of the service. CONCLUSION: Given the ongoing low utilisation of this service, we question whether this model is accepted by most GPs in our district. Possibly, they prefer more traditional models, where treatment is taken over by psychiatrists in the public or private system. We believe there is a need to increase the capacity and scope of publicly funded services to treat mental health problems.

STUDY OBJECTIVE: Little is known about the number of women who identify as lesbian. Estimates from the US range from 1% to nearly 10%. Accurate estimates are critical in order to meet lesbian's healthcare needs and to address health problems that may be more prevalent among them. This study used capture-recapture methods to estimate the lesbian population of Allegheny County, Pennsylvania. DESIGN: Mailing lists from four sources were used to identify lesbians. The capture-recapture method and log-linear modelling were used to estimate the number of lesbians in the defined geographical area, and the percentage of the female population they comprised there was determined through census data. SETTING: Allegheny County, Pennsylvania, USA. RESULTS: A total of 2185 unique names were identified. The capture-recapture method estimated that the total lesbian population of Allegheny County was 7031 (95% CI 5850 to 8576). Therefore, based on the 1990 census figures, the county's adult lesbian population was estimated to be 1.87% (95% CI 1.56% to 2.28%) of the adult female population. CONCLUSIONS: An estimate of the lesbian population is fundamental for addressing lesbian's health needs and for developing appropriate research programmes. Capture-recapture methods have the potential to provide accurate and reliable estimates of this population in any location.

Medical schools put little emphasis upon education on public health, even though public health has played an important role in this century. One way to harness its benefit in order to improve global health in the 21st century is to globally share lectures on public health through the Internet. We have developed the Supercourse comprising of web-based learning modules on epidemiology in a standardized format with the size of each web page less than 10 kilobytes. A cross-sectional observational study was conducted to investigate the association of the perception of the access speed to Web-based lectures by teachers with their perception of lecture quality. There were 223 teachers who rated the lectures: 72% were from North America or Western Europe, 40% had taught epidemiology, and 14% reported that the speed of access was slow. Odds ratio of above-average rating among those who reported that the speed of access was fast relative to those who reported that the speed of access was slow was 4.25 (2.03-8.91; P = 0.001). The odds ratios were similar and significant after taking into account several other factors, including the variation of rating across lectures, region, and experiences in teaching epidemiology. The results indicate that the perception of the quality of Web-based lectures is related to the speed of access to a web page. The speed of access may be as important, if not more important, as the content itself. This suggests that, to share educational materials on the Web globally for teachers, one must consider not only the content, but also how people at local sites gain access to the Internet.

OBJECTIVES: This study compared the prevalence of health behaviors among lesbians and in the general population of women. METHODS: We used a cross-sectional community-based survey of 1010 self-identified lesbians 18 years or older. RESULTS: Compared with the general population of women, lesbians were more likely to report cigarette use, alcohol use, and heavy alcohol use. A higher percentage of lesbians were categorized as overweight, and lesbians were more likely to participate in vigorous physical activity. They were less likely to report having had a Papanicolaou test within the past 2 years but more likely to report ever having had a mammogram. CONCLUSIONS: While there may be differences in health behaviors between lesbians and the general population of women, how these differences influence the risk of subsequent disease is unknown.

PURPOSE: This report describes the development and use of two self-report methods and an objective measure to assess longitudinal changes in physical activity in a large biethnic cohort of young girls from childhood through adolescence. METHODS: The NHLBI Growth and Health Study (NGHS) is a multicenter study of obesity development in 2379 black and white girls followed from ages 9-10 yr to 18-19 yr (NGHS years 1-10). A Caltrac activity monitor was used to objectively quantify activity levels in years 3-5. A 3-d diary (AD) and a habitual patterns questionnaire (HAQ) were administered annually and biannually, respectively, to subjectively quantify physical activity levels. The changing pattern of activities as the girls matured during the 10-yr study period necessitated periodic form changes. Empirical analytic approaches were developed to help distinguish between true longitudinal changes in activity levels from potential numerical artifacts resulting from modifications in forms. RESULTS: The longitudinal activity data indicate a steep decline in the level of reported activity from baseline to year 10 as indicated by AD scores (446.8 to 292.1 MET-min x d(-1), 35%) as well as by HAQ scores (29.3 to 4.9 MET-times x wk(-1), 83%). This parallel trend in the pattern of the decline in activity among the two self-report methods was mirrored by a similar decline using the Caltrac method of physical activity assessment. From years 3 to 5, the AD decreased by 22%, whereas both the HAQ and Caltrac declined by 21%. CONCLUSION: The longitudinal data on physical activity collected in the NGHS cohort further confirm a dramatic decrease in the overall level of physical activity during the transition from childhood to adolescence. The consistency among the three methods indicate that both the AD and HAQ are useful tools for the assessment of activity levels in adolescent girls.
