Sober adolescence–Predictor of psychosocial maladjustment in young adulthood?

We have explored how age at first intoxication with alcohol relates to mental health, social integration and adjustment to the adult role. The data stem from a longitudinal representative study of 2000 Norwegians. The sample was assessed at ages 19–22, 21–24 and 25–28. Among females, only early intoxication was related to young adult symptoms of poor mental health. A U-shaped association between intoxication debut and psychological problems was revealed among males, implying that both early and late beginners had more such problems than those who had followed the mainstream. These associations persisted without change over time. However, males who remained abstainers in adulthood were psychologically healthy, but they showed indications of a delayed entry into the adult role. Male late beginners were also somewhat reluctant to adopt adult role-behaviors. Thus, getting drunk for the first time in mid-adolescence seems to be an ingredient in the normal developmental process in young males.     

Integrating Systems of Care in California for Youth with Severe Emotional Disturbance IV: Educational Attendance and Achievement

Empirical results are presented from school-based interventions in three California counties that are pioneering participants in a carefully evaluated effort to create an innovative system of care for youth with severe emotional disturbance. Data are presented about the educational attendance and achievement of youth enrolled in clinical and academic programs designed to provide collaborative mental health and education services. Attendance levels were uniformly high. The youth were below expected grade level as measured by standardized tests at program admission. Across programs, two counties demonstrated grade level increases of one year or more for one year in school on all subscales of established measures of educational achievement. The third county demonstrated increases of slightly less than one year on two of three subscales of the educational achievement measures. These results are the first from a multisite demonstration of integrated education and mental health programs embedded within a broader system of care for youth. The findings, combined with those from our prior studies, illustrate that is possible to reduce and control placements in restrictive levels of care while improving the academic performance of a vast majority of the youth enrolled in specialized programs within the care systems.     

Blending qualitative and behavior analytic research methods to evaluate outcomes in inclusive schools

Following Haring's (1992) recommendation, we have utilized qualitative research techniques to assist us in designing a program of research on inclusive education which is responsive to the outcome values and priorities identified by teachers and parents. Using interviews, observations, and document analysis to follow 35 children in full inclusion classrooms over a period of two years, we have described outcomes for these children in three major domains. These outcome domains, and subthemes within them, have been evaluated and revised based on interviews and social validation ratings by parents and teachers. Dependent measures based on our qualitative research findings are currently being used in a series of behavior analytic studies designed to evaluate the effects of specific interventions on outcomes of inclusion for children with and without disabilities.     

Effects of ethanol on reinforced variations and repetitions by rats under a multiple schedule.

Response sequences emitted by five Long-Evans rats were reinforced under a two-component multiple schedule. In the REPEAT component, food pellets were contingent upon completion of a left-left-right-right (LLRR) sequence on two levers. In the VARY component, pellets were contingent upon variable sequences (i.e., a sequence was reinforced only if it differed from each of the previous five sequences). The rats learned to emit LLRR sequences in the REPEAT component and variable sequences in VARY. Intraperitoneal injections of ethanol (1.25, 1.75, and 2.25 g/kg) significantly increased sequence variability in REPEAT, thereby lowering reinforcement probability, but had little effect on sequence variability in the VARY component. These results extend previous findings that alcohol impairs the performance of reinforced repetitions but not of reinforced variations in response sequences.     

AN ANALYSIS OF THE PROCEDURAL COMPONENTS OF SUPPORTED EMPLOYMENT PROGRAMS ASSOCIATED WITH EMPLOYMENT OUTCOMES

This study examined the relation between the procedural components of supported employment programs and employment outcomes for 120 individuals with disabilities. These individuals were involved in supported employment programs established through the Utah Supported Employment Project. The results suggest that successful implementation of supported employment services led to ongoing employment of study participants in community work sites, increased wages, and ongoing opportunities for workers to interact with nondisabled peers. In addition, several procedural components were found to be strongly associated with successful employment outcomes for workers. Results of the study are discussed in terms of the training needs of supported employment program staff and future research for the dissemination of a cohesive technology of supported employment.     

Life engagement is associated with higher GDP among societies

Research suggests that individuals who report a greater sense of purpose in life tend to fare better economically, which may be expected to extend to the societal-level, in terms of higher GDP. However, previous work has demonstrated a negative association between citizens’ reports of purpose and GDP. The current study reconciles these differences by specifically considering an important component of sense of purpose missing in the past societal work, namely life engagement. Using data representative of 99% of the world’s adult population from 2013 to 2015 Gallup World Poll, results demonstrate a clear positive association between life engagement and countries’ GDP. Moreover, results demonstrate the distinctive importance of assessing life engagement relative to alternative metrics for related constructs.     

青少年的气质与烟酒使用:交互效应检验

考察气质(意志控制、愤怒挫折、感觉寻求)对青少年烟酒使用的主效应,气质与教养方式(权威、专制、纵容)对烟酒使用的交互效应以及气质间的交互效应.采用随机整群抽样的方法,选取660名青少年为被试,匿名完成气质问卷、教养方式问卷和烟酒使用问卷.结果显示:(1)在控制了性别、年龄、社会经济地位后,气质对青少年烟酒使用具有预测作用,低意志控制、高愤怒挫折、高感觉寻求正向预测烟酒使用;(2)教养方式调节部分气质因素与烟酒使用的关系,具体为:权威和专制教养缓冲感觉寻求的风险作用,符合风险缓冲模型;纵容教养增强感觉寻求的风险作用,符合风险增强模型;(3)气质内部在影响青少年烟酒使用时也存在交互作用,愤怒挫折增强感觉寻求的风险作用,符合风险增强模型.因此,烟酒使用是气质与教养方式及气质间交互作用的产物.     

阅读进度反馈信息对工作同盟和咨询效果的影响

进度反馈指将对当事人的标准化测量结果和解释反馈给咨询师的干预, 其目的在于矫正咨询师对咨询效果主观评估的偏差, 提高咨询效果。考虑到咨询师和当事人“面对面”的标准反馈程序不符合我国社会文化习惯, 采用多层结构方程模型, 分析了自然情境下非“面对面”的进度反馈对工作同盟和咨询效果的影响。结果发现, 在组间水平, 反馈组的工作同盟质量更好; 在组内水平, 工作同盟与症状是相互预测的关系。在结案时, 反馈组在抑郁症状和咨询的有帮助性上效果更好。结论是进度反馈对工作同盟和咨询效果有积极影响。研究从工作同盟和中国人的关系角度拓展了对进度反馈作用机制的认识, 为进度反馈的应用提供了基于实践干预有效的证据。
