Personality strengths in adolescence and decreased risk of developing mental health problems in early adulthood.

The aim of this study was to investigate whether personality strengths during adolescence are associated with decreased risk of developing psychiatric disorders, educational or occupational problems, violent or criminal behaviors, and interpersonal difficulties during early adulthood. A representative community sample of 688 mothers from upstate New York and their offspring was interviewed in the period of 1985-1986 (mean offspring age = 16 years) and in that of 1991-1993 (mean offspring age = 22 years). Results showed that youths with numerous personality strengths at the mean age of 16 years were at a decreased risk of developing psychiatric disorders, educational and occupational problems, interpersonal difficulties, and criminal behaviors at the mean age of 22 years. These associations remained significant after controlling for age, sex, socioeconomic status, verbal intelligence, preexisting psychiatric disorders, and corresponding problems at the mean age of 16 years. Although youths with fewer personality strengths who experienced numerous stressful events were at elevated risk of developing psychiatric disorders during early adulthood, those with a higher number of personality strengths at the mean age of 16 years did not share this vulnerability. We conclude that personality strengths during adolescence may contribute to a decreased risk of developing a wide range of adverse outcomes during early adulthood. Systematic evaluation of character strengths may improve the clinical assessment of adolescents.

Stimulating a normal adjustment: misbehavior, amphetamines, and the electroencephalogram at the Bradley Home for children.

This article uses an historical case study to describe the influence of social and contextual factors on the adoption of somatic approaches to children's misbehavior. The child guidance movement and the emergence of medicalized residential treatment facilities for children influenced the theoretical orientations of physicians treating children's behavior disorders in the United States in the 1930s. Charles Bradley and his colleagues at the Bradley Home in Rhode Island defined behavior disorders in social terms but investigated and treated misbehavior with somatic tools. The use of amphetamines and the electroencephalogram reorganized concepts of maladjustment along neurological lines, even as the research relied on the Home's social priorities. Electroencephalographic investigations especially shaped an organic concept of misbehavior. Ultimately, the somatic orientation obscured the central role of local context in Bradley Home physicians' research.

A collaborative approach to targeted treatment development for schizophrenia: a qualitative evaluation of the NIMH-MATRICS project.

INTRODUCTION: In 2002, the National Institute of Mental Health (NIMH) initiated a multistakeholder research process designed to stimulate the development and evaluation of medications targeting the cognitive deficits associated with schizophrenia. The first phase, Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS), sought consensus on laboratory measures for cognition, clinical trial outcome measures, and drug registration requirements. MATRICS constitutes a unique drug development model because it targeted a specific endophenotype of schizophrenia and because it engaged academic, industry, and government stakeholders in a consensus-oriented process. This study offers a preliminary qualitative evaluation of the NIMH-MATRICS project. METHOD: Interview data are used to describe how MATRICS participants regard 3 aspects of the development of cognitive medications: the definition of the treatment target, stakeholders' role in the early development process, and anticipated dissemination complexities. RESULTS: MATRICS participants describe the treatment target in highly varied ways and envision a wide range of public health benefits. MATRICS is perceived as inclusive, despite minimal representation from some end users. According to informants, clinical detection, documentation, and monitoring of cognition and functioning may prove problematic. More thoroughly than non-industry-employed informants, industry-employed MATRICS participants articulate strategies by which treatments can be integrated into clinical practice. DISCUSSION: The MATRICS process did not produce a clinical concept of cognitive impairment in schizophrenia, and significant challenges remain to be addressed regarding the rational clinical use of novel pharmaceuticals for cognition. Broader inclusion of end users in translational science projects may streamline implementation and facilitate improvements in real-world outcomes.

Generalizability of studies on mental health treatment and outcomes, 1981 to 1996.

OBJECTIVE: This study operationalized and measured the external validity, or generalizability, of studies on mental health treatment and outcomes published in four journals between 1981 and 1996. METHOD: MEDLINE was searched for articles on mental health treatment and outcomes that were published in four leading psychiatry and psychology journals between 1981 and 1996. A 156-item instrument was used to assess generalizability of study findings. RESULTS: Of more than 9,000 citations, 414 eligible studies were identified. Inclusion of community sites and patients from racial or ethnic minority groups were documented in only 12 and 25 percent of studies, respectively. Random or systematic sampling methods were rare (3 percent), and 75 percent of studies did not explicitly address sample representativeness. Studies with funding from the National Institute of Mental Health (NIMH) were more likely than those without NIMH funding to document the inclusion of patients from minority groups (30 percent compared with 20 percent). Randomized studies were more likely than nonrandomized studies to document the inclusion of patients from minority groups (28 percent compared with 17 percent), include patients with comorbid psychiatric conditions (31 percent compared with 19 percent), and attend to sample representativeness (28 percent compared with 15 percent). Modest improvements were seen over time in inclusion of patients from minority groups, inclusion of patients with psychiatric comorbidities, and attention to sample representativeness. CONCLUSIONS: Generalizability of studies on treatments and outcomes, whether experimental or observational, remained low and poorly documented over the 16-year period.

Elements of dynamics v: resiliency and the narrative.

Although clinicians and researchers are increasingly interested in understanding mental health, the systematic study of resiliency presents unique problems. Constructs of mental health have been used in epidemiologic, population-based studies of wellness. Sociability, self-efficacy, and a sense of meaning appear to be common attributes of resilient people. These attributes seem to benefit individuals over time and despite hardships. Yet research that identifies particularly resilient cohorts may have limited generalizability. Furthermore, constructs of mental health may not capture the variety and dynamism of adaptive coping. Person-centered research methods such as psychoanalytic case studies and ethnographies can supplement population-based studies of resiliency with valuable context and detail. Examples are given of narrative-based studies of resiliency.

Identification and characterisation of the posteriorly-expressed Xenopus neurotrophin receptor homolog genes fullback and fullback-like.

We have identified fullback and fullback-like, two Xenopus laevis neurotrophin receptor homolog (NRH1) genes. The sequences of Fullback and Fullback-like are very similar to that of the neurotrophin receptor p75NTR, in both their extracellular and their intracellular domains. As their names imply, fullback and fullback-like are expressed in essentially identical patterns in the posterior of the embryo from the early gastrula stage onward. At tailbud and tadpole stages transcripts are also present in dorsal somites and the head, in addition to the growing tailbud. This expression pattern differs from that of p75NTR, suggesting that fullback and fullback-like have different functions from p75NTR during early development.

Defining the protein repertoire of microneme secretory organelles in the apicomplexan parasite Eimeria tenella.

The apicomplexan pathogen Eimeria causes coccidiosis, an intestinal disease of chickens, which has a major welfare and economic impact on the poultry industry. There is an urgent need to identify molecules that are rational targets for drug design and novel vaccines against coccidiosis. Apicomplexan secretory organelles, including micronemes and rhoptries, are essential for invasion of the host intestinal epithelium and establishment of parasitism. However, relatively little is known about the precise molecular function of these organelles, partly because few organelle proteins have been characterized. In this study, proteomics tools have been harnessed to define the protein repertoire of micronemes. Purified microneme proteins from Eimeria tenella sporozoites were excised from two-dimensional (2-D) gels and analyzed using matrix-assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF-MS) and chemically assisted fragmentation (CAF)-MALDI with de novo sequencing. Peptide mass profiles were searched against the NCBI non-redundant (nr) database and against Eimeria-specific databases using the Mascot search algorithm, resulting in the identification of 37 of 96 spots excised from the 2-D gels. In addition, we have found CAF-MALDI to be a useful adjunct for identifying proteins, without the need for tandem MS. This global approach to protein characterization will be vital to gain greater understanding of the processes involved in apicomplexan host cell invasion.
