Predicting adolescent problem use of marijuana: development and testing of a Bayesian model.

This paper reports on the development and testing of a risk assessment index for problem marijuana use designed to guide teenagers through an extensive computer-based support system intended to help them improve marijuana-related behaviors. Bayesian decision theory, used as the basis of the index development process, offers the advantage of building the index on subjective judgments of experts and does not require a large empirical data base. The index was found to predict an independent panel's ratings of teenager risk, and predict the marijuana use of 10th graders using self-reports of their profiles in the 7th grade. Implications for future risk assessment developments are discussed.

The use and impact of a computer-based support system for people living with AIDS and HIV infection.

CHESS (the Comprehensive Health Enhancement Support System) is an interactive, computer-based system to support people facing AIDS/HIV Infection and other health-related crises or concerns. CHESS provides information, referral to service providers, support in making tough decisions and networking to experts and others facing the same concerns. CHESS is designed to improve access to health and human services for people who would otherwise face psychological, social, economic or geographic barriers to receiving services. CHESS has been evaluated in a random-assignment study with over 200 men and women living with AIDS and HIV infection. When CHESS was placed in subjects' homes for 3-6 months, use of CHESS was extremely heavy, with the average subject using CHESS 138 times for 39 hours. Compared with a control group which did not receive CHESS, subjects who used CHESS reported significantly higher quality of life in several dimensions, including social support and cognitive functioning. Users also reported significant reductions in some types of health care costs, especially inpatient services (hospitalizations). All segments of the study population used and benefited from CHESS, including women, minorities and those subjects with lower levels of education. Thus, CHESS appears to be an effective means of delivering education and support to the diverse populations which are affected by AIDS and HIV infection.

Will HIV-positive people use an interactive computer system for information and support? A study of CHESS in two communities.

A study of use of an interactive computer system (CHESS--Comprehensive Health Enhancement Support System) by HIV-Positive people was conducted in Madison and Milwaukee during Fall 1992 and Winter 1993. Computers were placed in homes, and use monitored by the computer. Results showed that the system was used heavily by both samples, and that gender (women used it more) age, (younger used it more), living arrangements (those living alone used it more), and need for health care information (those who felt the most need used it more) but not education predicted use of CHESS. The authors argue that heavy CHESS use by a wide variety of HIV-positive people suggests that the computer can overcome "information poor" barriers in health information campaigns.

A scale to measure restrictiveness of living environments for troubled children and youths.

Despite concerns about the restrictiveness of care and treatment procedures and settings for special populations, the concept of restrictiveness has seldom been defined or measured. This study describes the development of the Restrictiveness of Living Environments Scale (ROLES) for measuring the restrictiveness of residential settings for children and youths, including their own homes. Based on a literature review, the authors defined restrictiveness in terms of limits placed on freedom of movement or choice by the physical facility, by rules or requirements, and by conditions of entry and departure. The definition, along with a list of 27 residential settings for children, was sent to 389 child care professionals, who were asked to rate the restrictiveness of the settings on a 10-point scale, using a rating method designed to yield an interval scale. Ratings from 159 respondents, rounded to the nearest .5, were used to determine the relative position of the settings on the scale.

CHESS: a computer-based system for providing information, referrals, decision support and social support to people facing medical and other health-related crises.

CHESS (the Comprehensive Health Enhancement Support System) is an interactive, computer-based system to support people facing health-related crises or concerns. CHESS provides information, referral to service providers, support in making tough decisions and networking to experts and others facing the same concerns. CHESS will improve access to health and human services for people who would otherwise face psychological, social, economic or geographic barriers to receiving services. CHESS has developed programs in five specific topic areas: Academic Crisis, Adult Children of Alcoholics, AIDS/HIV Infection, Breast Cancer and Sexual Assault. The lessons learned, and the structures developed, will serve as a model for future implementation of CHESS programs in a broad range of other topic areas. CHESS is designed around three major desired outcomes: 1) improving the emotional health status of users; 2) increasing the cost-effective use of health and human services; and 3) reducing the incidence of risk-taking behaviors that can lead to injury or illness. Pilot-testing and initial analysis of controlled evaluation data has shown that CHESS is extensively used, is useful and easy-to-use, and produces positive emotional outcomes. Further evaluation in continuing.

Is social validity what we are interested in? Argument for a functional approach.

It is argued that neither the term social nor the term validity is best to identify the processes used or the results obtained in questioning consumers about the goals set, procedures employed, or outcomes achieved in habilitative programming. The term consumer satisfaction acknowledges the fact that it is essentially a collection of consumer opinions. The underlying intent of the process might be called habilitative validation, a name that seems to better guide our validation efforts. More important, in carefully considering consumer satisfaction assessment, it becomes clear that not only does consumer satisfaction itself need to be validated, but also that more objective methods can be used for assessing habilitative validity. However, legitimate uses still remain for consumer satisfaction measurement, as long as we do not mistake it for strong evidence of the habilitative validity of our goals, procedures, or outcomes.

Habits with potential as disorders. Prevalence, severity, and other characteristics among college students.

Little is known about the prevalence of the various habit disorders-such as pulling out one's hair, biting fingernails, or grinding teeth--and even less is known about the prevalence of lesser habits which, if exacerbated, may be costly enough to an individual to be labeled a disorder. Such superficially "purposeless" behaviors provided the focus of the present investigation. An initial group of 142 college students completed a pilot questionnaire to identify habits to be included in a survey. The final questionnaire was then administered to 286 college students. It asked about "purposeless habits," defined as those "repeated actions that appear to serve no useful purpose but that we continue to engage in anyway." Behaviors included habits involving the mouth, face, neck, fingers, hands, legs, hair, body, clothing, and objects. In addition to assessing the nature and severity of problems caused by each habit, the stimulus conditions influencing its probability, related behaviors, and attempts to stop the habit were assessed. The kinds of behaviors that could become habit disorders were found to be quite common. Clinical and theoretical implications of the results are discussed.

The functions of assessment: implications for selection and development of devices for assessing repertoires in clinical, educational, and other settings.

An attempt is made to identify the many different functions that assessment of an individual's repertoire can serve. Implications of these functions for the character of and evidence about assessment devices are suggested. The functions fall into two general groups, those which influence decisions regarding an individual learner, and those which influence policy, program development, and scientific knowledge. The first group of functions is presented in a rough chronological sequence such that they form a "behavioral assessment funnel," beginning with functions involving broad-band assessment to identify likely persons and skill areas, and narrowing to the precise pinpointing, monitoring, and follow-up functions. The contribution of behavior analysis and behavior therapy to assessment methodology in this sequence is identified as well as the areas where more traditionally conceived methods are still useful. The second group of functions and behavioral contributions to it are then discussed.
