Effects of a behavioral intervention on epileptic seizure behavior and paroxysmal activity: a systematic replication of three cases of children with intractable epilepsy.

Three children with very frequent refractory epileptic seizures underwent a behavioral intervention consisting of symptom discrimination, countermeasures, contingent relaxation, and positive reinforcement for correct responses in a systematic replication series. The studies involved a 6-h nonintervention base rate, a 6-h treatment phase, and a 6-h nonintervention follow-up under laboratory conditions for each child. Neurophysiologic and behavioral measures of the effects of treatment were made using electroencephalogram (EEG)-video equipment. Effects of treatment were assessed by using a random sample of EEG-video sequences in base rate and follow-up. Results showed that no significant reduction of either seizure behavior or paroxysmal EEG activity was found subsequent to training in discrimination of early paroxysmal activity and/or sensations preceding seizures. Both seizure behavior and paroxysmal activity were significantly reduced in all three cases following intervention with an adapted countermeasure technique. No additional effects could be noted subsequent to the application of either contingent relaxation or positive reinforcement for correct responses. Paroxysmal EEG changes and seizure behavior were highly correlated. Reduction of the clinical manifestation or seizure response by behavioral manipulation was accompanied by a reduction of the total amount of paroxysmal activity as measured by the EEG.

A systems analysis of psychobiology and behavior therapy. Implications for behavioral medicine.

This article examines some basic principles of systems theory and applies them to the integration of psychobiology and behavior therapy in the evolution of behavioral medicine. Using the concepts of whole/part relationships, level and emergent property, and self-regulation and disregulation, it is proposed that all behavioral therapies involve psychobiological processes, and therefore, indirectly impinge on physical health. It is argued that the distinction between behavior and biology is one of level, and, therefore, behavioral therapies are ultimately biobehavioral therapies having biobehavioral consequences. It is proposed that contrary to traditional reductionistic logic, modern advances in biology are providing strong justification for the importance of including psychological methods in treating diseases manifested at the biological level. Various clinical examples are used to demonstrate how systems theory can be applied to differential diagnosis and treatment, computing cost/benefit ratios of different treatments, and conducting comprehensive clinical research and evaluation. Assessing the interaction of biological, psychological, and social treatment modalities becomes the hallmark of responsible patient care. Implications of the systems conception of behavioral medicine for collaboration among health care providers, the training of future clinicians in different disciplines, and policy decisions regarding the larger social consequences of health care are considered.

Adverse effects of poor behavior management of an inpatient's difficult behaviors.

Behavior therapy has been shown to improve the functioning of institutionalized clients, but front-line staff often have difficulty implementing behavior therapy techniques. In the case described in this report, staff with inadequate training in behavior therapy inconsistently used negative and positive reinforcement in the attempt to reduce the aggressive behavior of an inpatient diagnosed as having schizophrenia, and the interventions were associated with an increase in assaults and related behavior. The case illustrates the effects of poor behavior management and the importance of data collection in evaluating clinical interventions.

[A study of health behavior of the elderly without occupation--correlation between participation in health examinations and health behavior].

A survey on the health behavior of inhabitants without occupations, aged 60 or over who lived in city A in Kagawa prefecture (400 people), was performed. The results are summarized as follows: 1. The rates of participation in the general health checkup and the screening for colon cancer were high. In females, significant correlations were observed between the rates of participation in health examinations/screenings and age, but they were not significant in males. 2. The rates of good health practices were high in the items "Taking breakfast", "No change of body weight", "Sleeping adequately" and "Drinking moderately or no drinking". The rate of "Exercise" for males was higher than for females, and the rate of "No smoking" was lower for males than for females. For females, a correlation was observed between the score of good health practices and age, and this score decreased with age, but in males there was no significant difference. 3. The rate of participation in health education or health consultation was about 40 percent, and the rate of participation was larger for female inhabitants than for male inhabitants. 4. Persons who participated in the health examinations/screenings had more healthful practices than who did not participate. A correlation was observed between the rates of participation in health examinations/screenings and "Exercise." 5. Persons who participated in health education or health consultation had more healthful practices than who did not participate. 6. Correlations were observed between the rates of participation in health examinations/screenings and the rate of participation in the health education, or health itself. In this analyzed sample population, the health behavior of primary prevention and secondary prevention were related to each other, and the existence of common factors among health behavior for primary prevention and secondary prevention was estimated. Differences were observed between males and females concerning correlations between health behavior and age. It is thus necessary to improve health behavior via a continuous approach to the lifestyle for women. We think that good health behavior which continues over a long period of time can be instilled by approaching the lifestyle at the time of retirement for men.

A retrospective measure of childhood behavior problems and its use in predicting adolescent problem behaviors.

Confirmatory factor analysis was used to support the dimensional structure of a four-factor retrospective measure of childhood behavior problems with a large, nonclinical adolescent sample. Acceptable levels of internal consistency and low-to-moderate levels of parent-adolescent interrater agreement were indicated for the four factors of attentional deficit/hyperactivity, oppositional behavior, conduct disorder symptoms and avoidance behaviors. The externalizing childhood problems (i.e., attentional deficit/hyperactivity, oppositional behavior, conduct disorder) were associated significantly with both internalizing (depression) and externalizing (e.g., alcohol consumption, delinquent activity) adolescent problem behaviors, as well as with an earlier age of onset for substance use. Avoidant behaviors in childhood were associated specifically with depressive symptomatology in adolescence. Results are discussed with regard to the role of childhood problems as precursors to adolescent/adult disorders.

The influence of behavior preceding a reinforced response on behavior change in the classroom.

The influence of behavior that immediately precedes a reinforced target response on the effectiveness of a reinforcement contingency was examined in two experiments with mentally retarded children in a special-education classroom. Two reinforcement schedules were examined in each experiment. For each schedule, a prespecified period of attentive behavior served as the target response. The schedules differed in whether inattentive or attentive behavior was required immediately to precede the target response. These schedules were examined with one child in a simultaneous treatment design using praise as the reinforcer (Experiment I), and with two children in separate reversal designs using tokens as the reinforcer (Experiment II). While attentive behavior increased under each schedule, the increase was greater when attentive rather than inattentive behavior preceded the reinforced response. The results indicated that the effect of a contingency may be determined not only by the specific response reinforced but also by the behavior that immediately precedes that response.

A comparison of response cost and differential reinforcement of other behavior to reduce disruptive behavior in a preschool classroom.

This study investigated the effectiveness of response cost and differential reinforcement of other behavior (DRO) in reducing the disruptive behaviors of 25 children in a preschool classroom. Using an alternating treatments design, disruptive behavior was reduced when the participants earned tokens for the absence of disruptive behavior (DRO) or lost tokens for the occurrence of disruptive behavior (response cost). Initially, DRO was more successful in reducing the number of disruptive behaviors; however, over time, response cost proved to be more effective.

The effects of conducting behavioral observations on the behavior of the observer.

Behavior-analytic approaches to occupational safety are often effective for improving safety in organizations, and have been successful in a wide variety of settings. The effects of these safety processes are thought to arise primarily from the behavioral observation process and the delivery of feedback. Typically, supervisors or employee observers involved in behavioral safety implementations conduct observations. The present study was an attempt to assess the effects of conducting observations on an observer's safety performance. An ABC multiple baseline counterbalanced across two sets of behaviors was conducted in a simulated office. The target behaviors involved knee and back positions during lifts; back, shoulder, and feet positions while sitting; neck and wrist positions while typing; and neck position during phone use. Substantial improvements in safety performance occurred after participants conducted observations on a videotape of a confederate's performance. The possible behavioral functions responsible for this change, and the implications of these findings for applied settings, are discussed.

Behavioral, physiological and functional aspects of stereotyped behavior: a review and a re-interpretation.

Stereotypies are repetitive actions that are fixed in form and orientation and serve no obvious purpose. Their occurrence in farm animals submitted to intensive husbandry has been interpreted to indicate inadequate environmental design or welfare. Over recent years, detailed descriptive studies have led to a better understanding of the organization and development of stereotypies, particularly in pregnant sows housed in tether stalls. Stereotyped behaviors appear to emerge from elements of initial defensive reactions of animals to their environment. They develop via a progressive narrowing of the behavioral repertoire, until only self-directed behaviors are displayed. Pharmacological studies suggest that performance of stereotyped behavior depends on the brain dopamine systems that are involved in selection and initiation of motor movements. However, generalization of these data to natural stereotypies is doubtful. Recent evidence favors an involvement of brain opioid peptides in stereotyped behavior of sows, although the exact mechanisms remain unknown. Stereotypies are typically observed in situations of conflict or frustration. They have been claimed to have an adaptive function, either by providing self-generated sensory stimulation to compensate for the lack of environmental stimulation, or by allowing animals to discharge their tension or anxiety. However, there is little evidence in favor of either interpretation. On the basis of present knowledge, it is proposed that stereotyped activities gain strength because of the positive feedback effect of sensory stimulation on their underlying control systems, which leads to a progressive sensitization of these neural systems. Stereotypies would then be simply the outward expression of an activation of lower brain structures controlling motor behavior which occurs in the absence of normal inhibitory control by higher nervous functions.

The role of self-efficacy in predicting rule-following behaviors in shelters for homeless youth: a test of the theory of planned behavior.

Through a prospective study of 70 youths staying at homeless-youth shelters, the authors tested the utility of I. Ajzen's (1991) theory of planned behavior (TPB), by comparing the constructs of self-efficacy with perceived behavioral control (PBC), in predicting people's rule-following behavior during shelter stays. They performed the 1st wave of data collection through a questionnaire assessing the standard TPB components of attitudes, subjective norms, PBC, and behavioral intentions in relation to following the set rules at youth shelters. Further, they distinguished between items assessing PBC (or perceived control) and those reflecting self-efficacy (or perceived difficulty). At the completion of each youth's stay at the shelter, shelter staff rated the rule adherence for that participant. Regression analyses revealed some support for the TPB in that subjective norm was a significant predictor of intentions. However, self-efficacy emerged as the strongest predictor of intentions and was the only significant predictor of rule-following behavior. Thus, the results of the present study indicate the possibility that self-efficacy is integral to predicting rule adherence within this context and reaffirm the importance of incorporating notions of people's perceived ease or difficulty in performing actions in models of attitude-behavior prediction.

[Effects of environmental change and others' behavior on cooperative behavior and solution preference in social dilemma].

This study examined how environmental change and others' behavior affected cooperative behavior and solution preference of the person in social dilemma situation. Participants in two experiments played an "environment game," in which gradual pollution in environment and reduction in profit rate were simulated. Information on behavior of other players was manipulated: in "free rider" condition, one person was an extreme free rider, and the others were cooperative; in "loafing" condition, everyone loafed. In both experiments, "Bad Apple Effect" was not observed clearly, and cooperative behavior increased as environmental pollution worsened. In Experiment 2, there was no main effect of others' behavior on solution preference. However, significant correlations were found among solution preference, motivation to control others' behavior, and perceived seriousness of the situation, only when an extreme free rider was among them.

State-specific prevalence of selected health behaviors, by race and ethnicity--Behavioral Risk Factor Surveillance System, 1997.

PROBLEM/CONDITION: In the United States, disparities in risks for chronic disease (e.g., diabetes, cardiovascular disease, and cancer) and injury exist among racial and ethnic groups. This report summarizes findings from the 1997 Behavioral Risk Factor Surveillance System (BRFSS) of the distribution of access to health care, health-status indicators, health-risk behaviors, and use of clinical preventive services across five racial and ethnic groups (i.e., whites, blacks, Hispanics, American Indians or Alaska Natives, and Asians or Pacific Islanders) and by state. REPORTING PERIOD COVERED: 1997. DESCRIPTION OF SYSTEM: The BRFSS is a state-based telephone survey of the civilian, noninstitutionalized, adult (i.e., persons aged > or = 18 years) population. In 1997, all 50 states, the District of Columbia, and Puerto Rico participated in the BRFSS. RESULTS: Variations in risk for chronic disease and injury among racial and ethnic groups exist both within states and across states. For example, in Arizona, 11.0% of whites, 26.2% of Hispanics, and 50.5% of American Indians or Alaska Natives reported having no health insurance. Across states, the median percentage of adults who reported not having this insurance ranged from 10.8% for whites to 24.5% for American Indians or Alaska Natives. Other findings are as follows. Blacks, Hispanics, American Indians or Alaska Natives, and Asians or Pacific Islanders were more likely than whites to report poor access to health care (i.e., no health-care coverage and cost as a barrier to obtaining health care). Blacks, Hispanics, and American Indians or Alaska Natives were more likely than whites and Asians or Pacific Islanders to report fair or poor health status, obesity, diabetes, and no leisure-time physical activity. Blacks were substantially more likely than other racial or ethnic groups to report high blood pressure. Among all groups, American Indians or Alaska Natives were the most likely to report cigarette smoking. Except for Asians or Pacific Islanders, the median percentage of adults who reported not always wearing a safety belt while driving or riding in a car was > or = 30%. The Papanicolaou test was the most commonly reported screening measure: > or = 81% of white, black, and Hispanic women with an intact uterine cervix reported having had one in the past 3 years. Among white, black, and Hispanic women aged > or = 50 years, > or = 63% reported having had a mammogram in the past 2 years. Approximately two thirds of white, black, and Hispanic women aged > or = 50 years reported having had both a mammogram and a clinical breast examination in the past 2 years; this behavior was least common among Hispanics and most common among blacks. Screening for colorectal cancer was low among whites, blacks, and Hispanics aged > or = 50 years: in each racial or ethnic group, < or = 20% reported having used a home-kit blood stool test in the past year, and < or = 30% reported having had a sigmoidoscopy within the last 5 years. INTERPRETATION: Differences in median percentages between racial and ethnic groups, as well as between states within each racial and ethnic group, are likely mediated by various factors. According to published literature, socioeconomic factors (e.g., age distribution, educational attainment, employment status, and poverty), lifestyle behaviors (e.g., lack of physical activity, alcohol intake, and cigarette smoking), aspects of the social environment (e.g., educational and economic opportunities, neighborhood and work conditions, and state and local laws enacted to discourage high-risk behaviors), and factors affecting the health-care system (e.g., access to health care, and cost and availability of screening for diseases and health-risk factors) may be associated with these differences. ACTION TAKEN: States will continue to use the BRFSS to collect information about health-risk behaviors among various racial and ethnic groups. (ABSTRACT TRUNCATED)

Human immunodeficiency virus (HIV) risk, prevention, and testing behaviors--United States, National HIV Behavioral Surveillance System: men who have sex with men, November 2003-April 2005.

PROBLEM/CONDITION: For CDC's goal of reducing the number of new human immunodeficiency virus (HIV) infections to be achieved, data are needed to assess the prevalence of HIV-related risk behaviors at a given time, monitor trends in these behaviors, and assess the correlates of risk. These data also can be used to evaluate the extent to which current HIV-prevention programs are reaching targeted communities and direct future HIV-prevention activities to reduce HIV transmission. REPORTING PERIOD: November 2003-April 2005. DESCRIPTION OF SYSTEM: The National HIV Behavioral Surveillance (NHBS) System collects risk behavior data from three populations at high risk for HIV infection: men who have sex with men (MSM), injection-drug users, and heterosexual adults in areas in which HIV is prevalent. Data collection began in 2003 among MSM in 17 U.S. metropolitan statistical areas (MSAs), and surveys have been conducted in 25 MSAs since 2005. Participants must be aged >/= 18 years and reside in a participating MSA. RESULTS: This report summarizes data gathered during the first cycle (i.e., data collection period) of NHBS (November 2003-April 2005) from approximately 10,000 MSM. The results indicated that >90% of participants had ever been tested for HIV. Of those, 77% had been tested during the preceding 12 months. In addition to their male sex partners, 14% of participants also had at least one female sex partner during the preceding 12 months. Unprotected anal intercourse was reported by 58% with a main male partner (someone with whom the participant had sex and to whom he felt most committed [e.g., a boyfriend, spouse, significant other, or life partner]) and by 36[corrected]% with a casual male partner (someone with whom the participant had sex but who was not considered a main partner). Noninjection drugs were used by 42% of participants during the preceding 12 months; the most commonly used drugs were marijuana (77%), cocaine (37%), ecstasy (29%), poppers (28%), and stimulants (27%). A substantial proportion (80%) of participants had received free condoms during the preceding 12 months, but fewer had participated in individual- or group-level HIV prevention programs (15% and 8%, respectively). INTERPRETATION: MSM surveyed engaged in sexual and drug-use behaviors that placed them at increased risk for HIV infection. The majority of MSM surveyed had been tested for HIV infection. Although a substantial proportion of participants had received free condoms, a much smaller proportion had participated in more intensive HIV-prevention programs. PUBLIC HEALTH ACTION: NHBS data are used to assess and develop effective HIV-prevention programs and services. Continued collection and reporting of NHBS data from all targeted high-risk populations is needed to monitor behavior trends and assess future HIV prevention needs in these populations. The data are used for local HIV-prevention planning and monitoring in MSAs in which NHBS is conducted.

AIDS risk behaviors among late middle-aged and elderly Americans. The National AIDS Behavioral Surveys.

OBJECTIVES: Although 10% of all acquired immunodeficiency syndrome (AIDS) cases diagnosed in the United States have been among Americans aged 50 years of age or older, little attention has been devoted to understanding AIDS risk-taking behaviors among middle-aged or older Americans. This study describes the prevalence of AIDS risk among Americans aged 50 years of age or older. DESIGN AND STUDY POPULATION: We present data from the National AIDS Behavioral Surveys, two large cross-sectional national surveys taken in 1990-1991. MAIN OUTCOME VARIABLE: Prevalence of risk behaviors for human immunodeficiency virus (HIV) transmission and of HIV testing. RESULTS: Findings from both surveys provide replication of several important points. First, the prevalence of having at least one risk factor for HIV infection was about 10% among Americans aged 50 years or older in both samples. Very small proportions of Americans past the age of 50 years with a known behavioral risk for HIV infection used condoms during sex or had undergone HIV testing. At-risk Americans past the age of 50 years were one sixth as likely to use condoms during sex and one fifth as likely to have been tested for HIV as a comparison group of at-risk individuals in their 20s. CONCLUSIONS: Despite the fact that HIV infection is clearly present among those past the age of 50 years, a small proportion of individuals in this age group take behavioral risks for HIV infection. High-risk individuals older than 50 years are much less likely to have adopted AIDS prevention strategies than are younger individuals who engage in the same behavioral risks.

[Individual differences in the reactions to acute stress related to behavioral type. Resistance (predisposition) to behavioral and sleep disorders].

Resistance (predisposition) to behavior and sleep disturbances after acute stress was studied in rats with different types of behavior in open field and forced swimming tests. The highest resistance to stress (the least alterations of behavior and sleep parameters) was found in rats with the active type of behavior, the least resistance to stress--in the middle group, and rats with the passive type of behavior held the intermediate position. The comparison of the present data with previously obtained results showed a positive correlation between the resistance to stress and the resistance to circulatory cerebral hypoxia induced by bilateral common carotid arteries occlusion. The biological significance of the association of resistance to stress and to cerebral hypoxia with the type of behavior is discussed.

[Behavior assessment in Alzheimer type dementia using the disruptive behavior questionnaire].

OBJECTIVES: We developed a disruptive behavior questionnaire designed for persons living close to the patient in order to assess behavior disorders in Alzheimer type dementia. METHODS: The study included 111 patients with criteria for diagnosis of Alzheimer type dementia. The questionnaire was used to assess the patients 15 days after withdrawal of psychotropic drugs. A partially-structured interview was also conducted by a psychiatrist in 20 cases. RESULTS: There was no relationship between the different behavior disorders and the mini-mental-state score or the social and cultural situation. Answers to the questionnaire and responses given during the interview were nearly identical. CONCLUSION: There has been little effort to assess behavior disorders compared with cognitive disorders in patients with Alzheimer type dementia. Behavior assessment should be an integral part of patient evaluation since cognitive and non-cognitive disorders are independent and certain therapeutics may be effective in behavior disorders.

Treatment of self-injurious behavior by a combination of reinforcement for incompatible behavior and overcorrection.

In two related studies, a combination of reinforcement for incompatible behavior and positive practice overcorrection was applied to the elimination of head-slapping and head-banging behavior exhibited, respectively, by two profoundly retarded boys. The design for both studies also included a period in which only reinforcement for incompatible behavior was applied. The results from Study 1 indicated that, while reinforcement had little effect in reducing the frequency of the learner's head slapping, the combination of reinforcement and overcorrection had an immediate effect in significantly reducing and eventually eliminating that behavior. A 4-month follow-up indicated no significant recurrence of the behavior. In Study 2, on the other hand, both reinforcement and the combination of reinforcement and overcorrection resulted in a significant increase in the frequency of the learner's head-banging behavior. Discussion centered on several research questions left unanswered by the differing effects of the procedures applied in both studies.

Appetitive and consummatory behaviors in the control of ethanol consumption: a measure of ethanol seeking behavior.

Models of ethanol self-administration in animals have demonstrated that ethanol can reinforce a variety of behaviors, independent of ethanol's caloric or fluid properties. However, the processes that control self-administration remain unclear. Determining factors related to ethanol seeking behavior, independent of consumption, is central to the concepts of intake regulation. The model described in this article proposes a method to separate the initial appetitive (seeking) behavior from the following consummatory (drinking) behavior to assess each behavior type. Rats were trained to lever press to gain access to a drinking tube connected to a fluid bottle containing either 10% ethanol or 3% sucrose for 20 min. When the response requirement to obtain access to the tube was increased, it was found that both solutions supported the same amount of responding (breakpoint was at approximately a fixed ratio 32 requirement), indicating equal reinforcer strength. However, regardless of the response requirement, if access to the fluids occurred, intakes were not changed. This suggests that factors besides those of reinforcer efficacy are important in controlling the size of the consummatory bout. Based on these findings, we believe that this model will be useful in determining factors related to seeking behaviors and the control of drinking bout size.
