Efficacy and Effectiveness of Child and Adolescent Psychotherapy and Pharmacotherapy

Decades of intervention research have produced a rich body of evidence on the effects of psychotherapies and pharmacotherapies with children and adolescents. Here we summarize and critique that evidence. We review findings bearing on the efficacy of psychosocial treatments and medications under controlled experimental conditions. We also report evidence, where available, on the effectiveness of both classes of treatment with clinically referred youth treated in real-world clinical contexts. In general, the large body of evidence on efficacy contrasts sharply with the small base of evidence on effectiveness. Addressing this gap through an enriched research agenda could contribute importantly to linking scientific inquiry and clinical practice—to the benefit of both ventures. This is one element of a multifaceted agenda for future research and for synthesis of research, which will require the interplay of multiple disciplines related to child and adolescent mental health.     

Opiate and digitalis receptor assays distinguish between neuroexcitant and inactive organochlorines and between anesthetics and convulsants

Specific binding of [3H]naloxone to rat brain tissue in vitro was inhibited by the excitant organochlorinated insecticides (OCI), by ether (E) and octanol (OCT), and by the convulsant indoklon (IND) and its anesthetic isomer, isoindoklon (ISO). In the presence of 100 mM NaCl the inhibition of naloxone binding by E, OCT and ISO was greatly potentiated, whereas that by OCI and IND was attenuated. KCl (100 mM) was equally effective as NaCl on the action of anesthetics, but the effect of the excitant drugs was, in contrast to NaCl, unaffected by KCl. Specific binding of [3H]ouabain in the absence of Na, was depressed by anesthetics and enhanced by neuroexcitants. In the presence of NaCl, which by itself inhibits ouabain binding to brain, both anesthetics and excitants enhanced ouabain binding. DDE, a non-insecticidal analog of DDT, and the dimethyl derivative of the OCI, lindane, were inactive in the receptor assays. These observations point to a unique isolated system which responds consistently to anesthetic agents as a class and, in a different way, to neuroexcitant compounds.     

Learning and forgetting new names and objects in MCI and AD

We studied how subjects with mild cognitive impairment (MCI), early Alzheimer's disease (AD) and age-matched controls learned and maintained the names of unfamiliar objects that were trained with or without semantic support (object definitions). Naming performance, phonological cueing, incidental learning of the definitions and recognition of the objects were tested during follow-up. We found that word learning was significantly impaired in MCI and AD patients, whereas forgetting patterns were similar across groups. Semantic support showed a beneficial effect on object name retrieval in the MCI group 8 weeks after training, suggesting that the MCI patients’ preserved semantic memory can compensate for impaired episodic memory. The MCI group performed equally well as the controls in the tasks measuring incidental learning and recognition memory, whereas the AD group showed impairment in this respect. Both the MCI and the AD group benefited less from phonological cueing than the controls. Our findings indicate that word learning is compromised in both MCI and AD, whereas long-term retention of newly learned words is not affected to the same extent. Incidental learning and recognition memory seem to be well preserved in MCI.

Satellite cells and myonuclei in young and elderly women and men

The overall aim of this study was to assess the effects of aging on the satellite cell population. Muscle biopsies were taken from the tibialis anterior muscle of healthy, moderately active young (age range, 20-32 years; n = 31) and elderly (age range, 70-83 years; n = 27) women and men with comparable physical activity pattern. Satellite cells and myonuclei were visualized using a monoclonal antibody against neural cell adhesion molecule and counterstained with Mayer's hematoxylin. An average of 211 (range, 192-241) muscle fibers were examined for each individual. Compared with the young women and men, the elderly subjects had a significantly lower (P < 0.011) number of satellite cells per muscle fiber but a significantly higher (P < 0.004) number of myonuclei per muscle fiber. The number of satellite cells relative to the total number of nuclei [satellite cells/(myonuclei + satellite cells)] was significantly lower in the elderly than in the young women and men. These results imply that a reduction in the satellite cell population occurs as a result of increasing age in healthy men and women.

Retrospective and prospective design and data

The study of the presentation, symptomatology and family characteristics of an exclusively adolescent sample of patients with borderline personality disorder (BPD) was undertaken. Twenty-four cases of borderline personality disorder, 20 females, 4 males, identified using chart review and meeting the criteria of the Diagnostic Interview for Borderlines (DIB) and DSM III-R, were matched with psychiatric controls. Adolescents with borderline personality disorder were found to have high rates of affective symptomatology with Axis I diagnosis of major depressive disorder - MDD (DSM-III-R), and high rates of interpersonal psychopathology, i.e., manipulation, devaluation, and a pervasive sense of boredom. The latter seem to be characteristic as for adults with borderline personality disorder. The families were particularly angry and volatile.     

Cortisol levels and depression in men and women using heroin and cocaine

Abnormalities in the hypothalamic-pituitary-adrenal (HPA) axis are well documented in men using illicit drugs and/or infected with HIV; however, less is known about HPA function, or the health consequence of HPA dysfunction, in their female counterparts. People with depression exhibit hypercortisolemia, and depression is common in people with HIV or substance use problems. The current study investigated cortisol secretion in 209 demographically matched men and women, stratified by their HIV and drug use status. Self-reported depressive symptoms were evaluated using a standardized, validated questionnaire (CES-D). Women reported more depressive symptoms than men (p=.01). Male and female drug users exhibited higher cortisol concentrations (p=.03), and were more likely to report depressive symptoms (p=.04), than non-users. Depression was related to elevated cortisol concentrations for the study population (p=.03), and women with elevated cortisol concentrations were significantly more depressed than all other participants (p=.05). While it is unknown whether high cortisol concentrations precede depressive symptoms or vice versa, these data indicate that higher cortisol concentrations are associated with depressive symptoms in heroin and cocaine users, and that this association is more pronounced in women than men. HIV status did not act in an additive or synergistic way with drug use for either cortisol or CES-D measures in the current study. Unique therapies to treat the endocrine and mental health consequences of illicit drug use in men and women deserve consideration as depressive symptoms, and high cortisol concentrations associated with depressive symptoms, differ by gender.     

相关性和一致性：这对相仿概念和测量方法的回顾与阐明

概述：一致性(agreement)和相关性(correlation)是两个广泛使用的概念,用来评估变量之间的关联。虽然二者相似且相关,但是它们代表关联完全不同的概念。评估变量之间的一致性假设变量测量的是相同的结构,而在变量测量完全不同的结构时也可以评估它们之间的相关性。这种概念上的差异就要求使用不同的统计方法,并且当评估一致性或相关性时,统计方法根据数据的分布和研究者的兴趣可能会有所不同。例如, Pearson相关性,作为评估连续变量之间相关性的一种普遍测量方法,只有用于符合线性关系的变量时才能提供有用的信息;当用于不符合线性关系的变量时就无法提供准确信息甚至会产生误导。同样地,内部相关性,作为一种评估连续变量之间一致性的常用方法,如果一致性不好的实质正好是研究兴趣所在,那么该测量就不能为研究者提供充分的信息。本报告回顾了一致性和相关性的概念,并讨论了几种常用方法在应用中的差异。
