Work,stress, and well-being

Work-related stress may lead to injuries and psychological disorders. The National Institute for Occupational Safety and Health has identified psychological disorders as one of the ten leading work-related diseases and injuries during the 1980s (Sauter, Murphy, & Hurrell, 1990). This article sets out a framework, strategy, and recommendations for enhancing stress management skills and the psychological well-being of individuals in occupational environments. Central to the strategy are attention to work design variables, such as control, uncertainty, conflict, and task demands, surveillance of psychological disorders in the workplace, education of managers and workers concerning psychological well-being and stress in the workplace, and treatment of individuals in distress.     

The Effect of Research with Teenage Mothers on the Development of Their Infants1

Mother-infant interaction of 14 teenage mothers and 12 women 20 years or older was observed and recorded in the laboratory or the home when the infants were 16, 20, 24, and 52 weeks of age. In order to assess the possible effect of the research intervention on the maternal behavior and on the infants' development, a control group of teenage mothers and their infants was seen only at the end of the study when the infant was 52 weeks old. At 12 months the Home Observation Measure of the Environment Inventory (HOME) was administered and infants were assessed with the Bayley Scales of Infant Development (motor and mental scales) and the Ainsworth Strange Situation procedure. On all measures the observation groups scored significantly higher than the control group. The significant aspects of the research intervention are discussed.     

Decision making, movement planning and statistical decision theory

We discuss behavioral studies directed at understanding how probability information is represented in motor and economic tasks. By formulating the behavioral tasks in the language of statistical decision theory, we can compare performance in equivalent tasks in different domains. Subjects in traditional economic decision-making tasks often misrepresent the probability of rare events and typically fail to maximize expected gain. By contrast, subjects in mathematically equivalent movement tasks often choose movement strategies that come close to maximizing expected gain. We discuss the implications of these different outcomes, noting the evident differences between the source of uncertainty and how information about uncertainty is acquired in motor and economic tasks.     

Evaluation of “staying on track”: An early identification,tracking, and referral system

The “Staying on Track” project tracked infants, preschoolers, and their families in Brockville, Ontario, Canada for a period of 3 years. Public health nurses at preassigned intervals provided information and counseling for families and made referrals to other agencies if problems were judged to be beyond the expertise of the “Staying on Track” staff. To assess the effectiveness of the program in improving child development, a cohort design was selected to allow development to be assessed over 5½ years in 3 years. Three cohorts and a comparison group were included in the study. Each cohort received different procedures for identification and tracking. Cohort 1 received at least four home visits, cohort 2 received three clinic visits, and cohort 3 received one clinic visit. Intervention and follow-up from these visits included home visits, phone calls, and referrals for all three cohorts. Comparing cohort 1 to cohort 2 at 18 months, highly significant effects were found; few significant differences were found at 3½ years between cohort 2 and 3 and very few positive effects were found for 5½-year-old children who had been in the tracking system since they were 3½ years of age. The results are discussed and recommendations are made about the implications of the study for service provision. © 1998 Michigan Association for Infant Mental Health     

Moderator influences of informal experimenter support

This study examined the effect of experimenter support during an intensive 1-year research project on teenage mothers and their infants at 1 and 3 years of age. A variety of information concerning the infants' developmental levels, the mothers' psychological and sociological status, and the mother-infant interaction was collected at both ages. Results indicated that the positive effects of informal support at 1 year of age were no longer evident in mother or child 2 years later. The findings are discussed in light of the effects of observational research and possible implications for intervention programs for teenage mothers.

Time urgency: the construct and its measurement

Time urgency may be an important construct in industrial and organizational psychology. Preliminary analyses have indicated that time urgency may be multidimensional, and available self-report measures have been criticized on psychometric grounds. The present research addressed the dimensionality of time urgency. Behaviorally anchored rating scales (BARS), in which behavioral statements are substituted for qualitative anchors, were used to construct time urgency measures. The BARS technique produced multidimensional measures of time urgency that possessed adequate reliability and construct validity. The scales were tested on a wide variety of subjects. It is concluded that time urgency is a multidimensional construct. Relationships between the time urgency measures, job satisfaction, and work stress are discussed in light of previous research findings.     

Who is buying bioethics research?

Growing ties to private industry have prompted many to question the impartiality of academic bioethicists who receive financial support from for-profit corporations in exchange for ethics-related services and research. To the extent that corporate sponsors may view bioethics as little more than a way to strengthen public relations or avoid potential controversy, close ties to industry may pose serious threats to professional independence. New sources of support from private industry may also divert bioethicists from pursuing topics of greater social importance, such as the needs of medically underserved communities. To inform ongoing debates about the financing of bioethics and its transparency to those concerned about potential sources of bias, we examined funding disclosures appearing in original research reports in major bioethics journals. Reviewing research published over a 15-year period, we found little evidence that for-profit corporations are influencing bioethics research directly. Instead, we found evidence that a great number of organizations, both public and private, support bioethics research. These findings suggest that worries about the cooption of bioethics research by a few interested stakeholders are greatly overstated and undersupported by available data.
