EFFECTS OF PROBLEM DIFFICULTY AND REINFORCER QUALITY ON TIME ALLOCATED TO CONCURRENT ARITHMETIC PROBLEMS

Students with learning difficulties participated in two studies that analyzed the effects of problem difficulty and reinforcer quality upon time allocated to two sets of arithmetic problems reinforced according to a concurrent variable-interval 30-s variable-interval 120-s schedule. In Study 1, high- and low-difficulty arithmetic problems were systematically combined with rich and lean concurrent schedules (nickels used as reinforcers) across conditions using a single-subject design. The pairing of the high-difficulty problems with the richer schedule failed to offset time allocated to that alternative. Study 2 investigated the interactive effects of problem difficulty and reinforcer quality (nickels vs. program money) upon time allocation to arithmetic problems maintained by the concurrent schedules of reinforcement. Unlike problem difficulty, the pairing of the lesser quality reinforcer (program money) with the richer schedule reduced the time allocated to that alternative. The magnitude of this effect was greatest when combined with the low-difficulty problems. These studies have important implications for a matching law analysis of asymmetrical reinforcement variables that influence time allocation.     

Psychosocial Predictors of Health Status and Health Care Costs among People with Fibromyalgia

The purpose of the present study was to examine the effects of psychosocial characteristics on health status and the relationship between health status and health care use and costs in a group of people with fibromyalgia (FMS) over a 1-year period. The participants were 600 members of a large health maintenance organization. Demographic characteristics (age, education, employment status, ethnicity and income), need variables (comorbid conditions and baseline health status), and psychosocial variables (self-efficacy, helplessness, coping, and depression) were examined. Better health status at baseline, use of emotion-focused coping, and higher self-efficacy predicted better health status the following year. Higher health care use at baseline, being Caucasian, being older, and having more co-morbid conditions predicted higher health care use at 1 year. Only health care costs at baseline predicted health care costs the following year. Our results indicate that health care use and cost tend to be stable. Intense interventions focused on changing patterns of health care use and methods for coping with the change need to be developed and tested.     

Psychopathology,family functioning,and cognitive style in urban adolescents with suicide attempts

This study examined psychopathology, family functioning, and cognitive style in 121 African-American adolescents who attempted suicide. Group means suggested that these youths, when taken together, were not reporting significant psychological distress. However, after classifying the youths into three groups by level of depressive symptoms interesting findings emerged. Youth self-reports of depressive symptoms on the Children's Depression Inventory were associated with the presence of internalizing and externalizing disorders on the Youth Self-Report and Child Behavior Checklist, and with a maladaptive attributional style. Sixty-seven percent of participants classified their family types as maladaptive in terms of levels of cohesion and/or adaptability. In fact, the majority of adolescents and parents reported their families as disengaged. These findings are discussed from a culturally and developmentally sensitive framework which considers key demographic variables (race, socioeconomic status, age). Clinical implications are offered for individual and family interventions.     

The effects of a community-based literacy program on young children's language and conceptual development

Effects of a community-based literacy program on 1−, 2−, and 3-year-old children's language and conceptual development were assessed. University students were trained to teach Head Start parents effective methods for reading to their children. Families were randomly assigned to receive 18, 3, or 0 instructional visits. Results indicated that parents in the 18-instructional-visit program increased their participation in appropriate literacy behaviors such as reading to their children, teaching concepts to their children, and using the library, more than parents in the 0-instructional-visit groups. Children in the 18-instructional-visit program showed greater gains in language and conceptual development than children in the 0-instructional-visit group. Few differences were found between children in the 3-visti and 0-instructional-visit groups. Thus, only a high-intensity community-based intervention designed to train parents was effective in increasing emergent literacy in low-income ethnic children.

Perceived Benefits and Challenges of a Multiethnic-Racial Identity: Insight From Adults With Mixed Heritage

The purpose of this inquiry was to explore the lived experiences of multiethnic-racial individuals (i.e., individuals with parents from different ethnic-racial groups). In-depth interviews were conducted with 29 adults from the United States with mixed ethnic-racial backgrounds ranging in age from 18 to 52 (female n = 20, male n = 9). We identified a number of themes related to perceived benefits (e.g., pluralistic world views, stronger sense of self) and challenges (e.g., identity tensions, communal concerns) of having a mixed heritage. Findings are discussed in terms of four considerations for ethnic-racial identity of individuals with mixed ethnic-racial backgrounds: emphasizing constellations of experiences, life-span and developmental considerations of identity, (mixed) ethnic-racial identity as constituted in interactions, and the potential promise of pluralistic world views.     

Educating Hopes

Acknowledging the negative impact poverty and violence can have on the educational process, I explore ways in which a pragmatic interpretation of hope can guide us in formulating preventive and responsive measures that are not intrusive on the normal curriculum. I draw on key pragmatic ideas presented by John Dewey to emphasize the habits central to a pragmatic theory of hope. Equally important is the notion of a community of hope that fosters the development of hope’s habits. A hopeful pedagogy enables us to fund students with habits that help them resist the disconnection and despair that can come from living and learning amid impoverished or violent conditions. I argue that teachers can emphasize hope’s relevance to achieving the goals of the curriculum; they can also promote students’ self-knowledge through personal narratives that identify past accomplishments and explore possible means to desired goods. To begin ameliorating the tenacious conditions that foster poverty and violence, we need to look beyond the confines of the classroom and school to the resources and coordinated efforts made possible by the larger community. A pragmatic interpretation thus focuses our attention on individual and communal habits that help us secure desired goods. My discussion demonstrates at least some of the ways in which hope is a valuable resource for actively responding to circumstances that impede the educational process.     

A Cost Analysis of Self-Management Programs for People with Chronic Illness

The soaring cost of health care is a national problem that needs response at multiple levels, including that of the community. Reducing or limiting health care costs through interventions that emphasize the self-management of health may promote broader health care coverage, better quality of health care, and a sense of control over one's health. Therefore, it behooves community psychologists to perform cost analyses when testing interventions for people in a community. The present study investigated the effects of social support and education interventions on psychosocial variables, health status, and health care costs in older people with osteoarthritis. Participants were 363 members of a health maintenance organization (HMO), 60 years of age and older, with osteoarthritis. Participants were randomly assigned to one of three intervention groups (social support, education, or a combination of both) or to a control group. The results indicated that feelings of helplessness decreased in the intervention groups but not in the control group. All groups showed increases in self-efficacy and overall health status. In addition, health care costs increased less in the intervention groups than in the control group. Cost analysis was used to demonstrate that the monetary savings of the intervention greatly outweighed the cost of conducting the intervention. It appears that interventions can limit health care costs while improving health and increasing feelings of control for older people with osteoarthritis. Further, this paper demonstrates how a cost-benefit focus can benefit community studies.     

An examination of the physical health, health care use, and psychological well-being of spouses of people with fibromyalgia syndrome.

The present study compared the physical and mental health and the health care use of spouses of patients with fibromyalgia syndrome (FS group; n = 135) with that of spouses of healthy individuals (n = 153). FS group participants reported lower health and affective states and scored higher on depression, loneliness, and subjective stress than comparison group participants (p < .017). Husbands in the FS group who reported more illness impact and whose wives reported worse sleep quality and less self-efficacy had more psychological difficulties. No differences were found in health care costs between groups. These findings suggest that chronic illness in a partner may negatively affect an individual's physical and mental health.
