Socioenvironmental experiences,self-esteem,and emotional/behavioral problems in early adolescence

Tested the role of self-esteem as a mediator of relationships between socioenvironmental experiences and emotional/behavioral problems using a sample of 215 young adolescents (Grades 7–9). Socioenvironmental experiences were assessed using self-report questionnaire measures of social support and major and minor stressful events. Self-esteem was assessed using a self-report questionnaire, an interview, and a parent-report questionnaire. Emotional/behavioral problems were assessed using self-report, parent-report and teacherreport questionnaires. Utilizing structural equation modeling, the data were used to test a model in which self-esteem mediated the relationship between socioenvironmental experiences and emotional/behavioral problems. The hypothesized model provided a reasonably good fit to the data (normed fit index=.90). However, an alternative model which also allowed for direct effects of socioenvironmental experiences on emotional/behavioral problems produced a significant improvement in model fit. In this model, socio-environmental experiences had significant effects on emotional problems via both direct effects and indirect effects that indicated a mediating role for self-esteem. Only direct effects of socioenvironmental experiences were evident for behavioral problems. This research was supported by a grant to the first author from the University of Missouri Research Board. Thanks are due to the students, staff, and parents of the Columbia Public Schools, Columbia, Missouri, for their participation in and support of this research project.     

Residential Water Use: Predicting and Reducing Consumption1

This project had two goals: to explain variation in residential water consumption and to evaluate methods of encouraging residents to reduce their consumption. Survey data for both studies were collected by mail questionnaire in early 1991, and water consumption figures were recorded between June and August of that year. In Study 1 (n = 264) a three-variable regression model (number of residents, clothes washing machine loads, and property value) accounted for 60% of the variance. Attitudes, habits and values were very poor predictors of water consumption. In Study 2 (n =226) households were divided into three treatment groups: feedback only, feedback and dissonance, and a control group. Repeated-measures ANOVA revealed that high consumers receiving dissonance and feedback or feedback alone had significantly reduced their water consumption in the treatment period. The implications of these findings are discussed.     

The Role of Auditory Cues in the Detection of State Anxiety 1

Detecting anxiety is essential in both help-giving settings and in everyday social relationships. The studies reported here represent a follow-up to an earlier set of studies in which observers (raters) accurately identified others' (expressers') state anxiety using either video-only cues or audio-video cues. The earlier studies had included expressers who were repressors and nonrepressors, while the present studies included only nonrepressors. Observers viewedheard selected segments of previously videotaped expressers' self-reported high and low state anxiety experiences. Surprisingly, unlike the earlier studies, state anxiety was significantly inaccurately evaluated when video-only cues were used, but when audio cues were available, state anxiety was correctly identified. Information in video-only cues seemed to mislead observers since low compared with high state anxiety was rated as more anxious. These studies, and the significant comparison between studies with audio cues present and with audio cues absent, indicate the impact of auditory cues in detecting state anxiety in others.     

Automation for clinicians in the field: The validity of a performance support system

The Mental Retardation-Expert (MR-E) is an electronic performance support system for clinicians who work with mentally retarded persons who have behavioral disorders. It provides treatment planning assistance when needed. This study compares MR-E’s advice with that offered by human experts. It assesses the impact of the system on clinicians from various areas. The results support MR-E’s validity and its ability to help clinicians function as experts. They high-light potential benefits for psychologists in using performance support systems.     

Clients' suitability for counselling: The perception of counselors working in general practice

This study investigated the attitudes of 112 counsellors in general practice towards various factors concernig the selection of clients. Response indicate that counsellors are influenced, not only by diagnostic criteria, and other factors relating to the client, but also issues relating to the counsellor and the setting in which she or he works. The diagnostic critreria whcih seem to be considered most important are desire for change, motivation for therapty and evidence of psychopathology, althoug there is no clear consensus about the criteria overall. Importance varied according to the age and sex of the counsellor, but not by the experience, training, model of working, desire for further training, or number of sessins available.     

The Commercialization of Clinical Genetics: An Analysis of Interrelations Between Academic Centers and For-Profit Clinical Genetics Diagnostics Companies

The field of clinical genetics has undergone substantial commercialization, including the development of genetics diagnostics companies. Numerous for-profit corporations now offer genetic diagnostic services; until recently, these clinical services were provided almost exclusively through academic, not-for-profit medical centers. Some of these for-profit corporations have business and/or research relationships with academia. An evaluation of the interconnections between academia and the clinical genetics industry is an important first step in analyzing the risks and benefits of commercialization. We analyzed the personnel and business affiliations of 19 major U.S. for-profit clinical genetics diagnostics companies with universities, academic medical centers, and the scientific and medical genetics communities in a 2-year period, 1991–1992. We noted extensive connections between the for-profit sector and academia. At least 17% of high-ranking personnel and 85% of consultants for the companies had one or more academic ties. At least 68% of the companies had one or more business agreements with at least one university or academic medical center. These results raise many issues regarding the delivery of genetic medicine and the structure and function of academic medical genetics centers.     

The KIM-1 microcomputer as an eight-channel data logger

A machine language program and interface hardware to operate the KIM-1 microcomputer as an eight-channel data logger are described. All channels can operate simultaneously, and the data are stored in a specified area of memory. Double precision is used, enabling numbers greater than 255 to be recorded. Data can be collected over sampling intervals of 1 to 255 times 5 sec or 1 to 255 times 10 min. The time base is derived from 50- or 60-Hz mains ac. A method of transferring the data to a PET microcomputer and storing it on eight separate tape or disk files is also given.     

Network interference and number-fact retrieval: evidence from children's alphaplication.

The origins of several phenomena of number-fact retrieval were investigated by having children in Grades 3 and 4 memorize alphaplication facts (arithmetic-like memory items composed of letters instead of numbers). Alphaplication performance paralleled memory for arithmetic facts in several important respects: Results showed (a) a large performance advantage for tie (e.g., E, E = j) over nontie problems (E, I = p), (b) that most errors involved answers from the correct alpha-table, (c) that response times and error rates were strongly correlated across problems, (d) that the correct answers to poorly learned problems tended to be the most common error responses, and (e) that performance was lower for problems introduced later in the learning sequence. Taken together, these findings support a network-interference approach (Campbell & Graham, 1985) to memory for arithmetic facts.     

Male Partners' Appraisals of Undesired Pregnancy and Abortion: Implications for Women's Adjustment to Abortion

The impact of men's attributions for pregnancy and expectations for coping with abortion on their partner's post-abortion adjustment was examined. Men's and women's attributions and coping expectations were assessed in a sample of 73 couples prior to obtaining a first-trimester abortion of an undesired pregnancy. Women's depression was assessed 30 minutes post-abortion. Partners did not differ in their coping expectations or attributions of the pregnancy to chance, situation, another person, or their own behavior, but men blamed the pregnancy more on their own character than did their partners. Male partner's coping expectancies affected women's adjustment only if the women themselves had low coping expectancies. Among women with low coping expectancies, those accompanied by partners who also had low coping expectancies were the most depressed. Men's attributions were unrelated to their partner's adjustment.     

The power of a place: Opening the college classroom to people with serious mental illness

Presented the structure and implementation of a university-based practicum course on social relationships for people with serious mental illness and college undergraduates. Grounded in an ecological view of social settings, cooperative learning models of education and mutual help principles, the practicum was designed to create a collaborative classroom setting where undergraduates and people with serious mental illness could both develop and enhance their own interpersonal skills and social network ties. The practicum demonstrates how a university can use its resources to help address community needs while simultaneously enhancing its mission of teaching and research. The role of social context in creating collaborative relationships among participants and the use of the university as a community resource are discussed.
