Improving Mental Health Service Utilization for Children and Adolescents.

Approximately 10% of children and adolescents have mental health problems necessitating intervention, but well below 50% of these children receive needed services, and far fewer receive the quality of care required to effectively reduce their impairments. Although system reform is needed to improve service utilization and quality of care for all children, preschoolers, girls, individuals of minority status, and the uninsured are most at risk for being underserved. Factors contributing to poor service utilization can be classified into two broad sets: sociopolitical factors referring to issues related to funding and access, and cultural/familial factors including beliefs about mental health services, providers, and treatments. This article describes the help-seeking process and focuses on cultural and familial factors that contribute to movement through these stages, with a particular focus on variables that are amenable to change by practitioners in the school and community, including school psychologists. Guidelines for understanding and changing the help-seeking behavior of families, including suggestions for creating service options, providing family education, and offering individualized family services, are described.

Enzyme linked immunosorbent assay for detecting benzodiazepines in urine

A relatively simple ELISA technique was developed for the detection of a range of benzodiazepines (BZs) in urine. The assay employs a mouse anti-oxazepam antibody that is highly specific for the BZs. The limit of detection using 10 microliters samples of urine was 0.3 microgram ml-1 oxazepam. N-Desmethyldiazepam showed equal cross-reactivity to oxazepam, 11 BZs cross-reacted weakly and flurazepam and chlordiazepoxide did not cross-react at levels reported to be found in urine. No cross-reactivity was observed with drugs of abuse and a range of therapeutic drugs commonly found in urine. The assay was used as a screen to detect the presence of BZs in urine from 88 addicts that had been screened by the EMIT technique and a radioreceptor assay (RRA) for BZs. The ELISA produced two false negatives that were EMIT and RRA positive whereas the EMIT produced four different false negatives that were positive by both ELISA and RRA. Thirty-three positives were common to all three assays. The ELISA was also used to monitor nitrazepam-like activity in the urine of a greyhound receiving 5 mg oral medication and the results were compared with those obtained by RRA. Both assays were able to detect nitrazepam-like activity for up to 10 h post-administration.     

Decomposing words into their constituent morphemes: Evidence from English and Hebrew.

Participants segmented and shifted a sequence of letters from a source word to a target word and then named the product aloud. Morphemic and nonmorphemic letter sequences (e.g., EN) from phonemically matched words such as HARDEN and GARDEN were compared. In 4 experiments, naming latencies were faster for morphemic sequences than their nonmorphemic controls in both English, in which the morphemic status of the shifted sequence was varied and sequences were appended after the base morpheme (linearly concatenated), and in Hebrew, in which morphological transparency of the root (base morpheme) was varied and 1 morpheme was infixed inside the other (nonconcatenative) so that the phonological and orthographic integrity of the morphemic constituents was disrupted. Moreover, the likelihood with which both affixes and bases combine to form words influenced segment shifting times. In conclusion, skilled readers are sensitive to the morphological components of words whether or not they form contiguous orthographic or phonological units.

The relation between adolescent alcohol use and peer alcohol use: A longitudinal random coefficients model.

Longitudinal latent growth models were used to examine the relation between changes in adolescent alcohol use and changes in peer alcohol use over a 3-year period in a community-based sample of 363 Hispanic and Caucasian adolescents. Both adolescent alcohol use and peer alcohol use were characterized by positive linear growth over time. Not only were changes in adolescent alcohol use closely related to changes in peer alcohol use, but the initial status on peer alcohol use was predictive of later increases in adolescent alcohol use and the initial status on adolescent alcohol use was predictive of later increases in peer alcohol use. These results are inconsistent with models positing solely unidirectional effects between adolescent alcohol use and peer alcohol use.

Yukawa's Heavy Quantum and the Mesotron (1935-1937)

The unified “standard model’ of strong and weak nuclear forces of the mid-1930s was based on the emission and/or absorption of an electron and a neutrino, the so-called Fermi field, by the proton and the neutron. However, theorists could never explain simultaneously the required nuclear properties, such as saturation, strength, range, and charge independence of nuclear forces, while also accounting for β-decay. Yukawa proposed to exchange, instead of the Fermi field, the massive charged quanta of a new field which he invented, the U-field. His theory, however, languished for about two years. In this paper we describe this central episode in the history of elementary particle physics from Yukawa's proposal, published in 1935, to the year 1937 when particles resembling the quanta of the U-field were detected in the cosmic rays.     

Substance use and symptomatology among adolescent children of alcoholics.

Assessed the magnitude and specificity of parental alcoholism as a risk factor for internalizing symptomatology, externalizing symptomatology, and alcohol and drug use in adolescence. Parents' and children's reports of symptomatology and children's reports of alcohol and drug use were evaluated in a community sample of 454 adolescents. The results showed that parental alcoholism was a moderate to strong risk factor, with stronger risk associated with recent (rather than remitted) parental alcoholism. Multivariate analyses showed that the specificity of risk varied with the outcome measure. In predicting externalizing symptomatology, the risk associated with parental alcoholism was mediated by co-occurring parental psychopathology and environmental stress. However, in predicting alcohol use, the father's alcoholism was a specific risk factor above and beyond the more generalized effects of stress and family disruption.

Nicotine patch and self-help video for cigarette smoking cessation.

A total of 424 smokers were randomized in a 2?×?2 factorial experiment. A pharmacologic factor contained 2 levels: transdermal nicotine patch (TNP; 21 mg) and placebo. A self-help behavioral treatment factor contained 2 levels: video-enhanced self-help treatment manual and self-help treatment manual only. At 2 months, TNP produced a higher level of abstinence (36%) than placebo (20%), p?
