Understanding and promoting AIDS-preventive behavior: insights from the theory of reasoned action

Psychological determinants of AIDS-preventive behaviors were examined from the perspective of the theory of reasoned action in prospective studies of gay men, heterosexual university students, and heterosexual high school students. Across samples, preventive behaviors, and prospective intervals of 1 and 2 months' duration. AIDS-preventive behaviors were predicted by behavioral intentions; behavioral intentions were a function of attitudes and norms; and attitudes and norms were a function of their theorized basic underpinnings. Discussion focuses on the development of AIDS-prevention interventions that modify intentions, attitudes, and norms concerning performance of AIDS-preventive behaviors by targeting the empirically identified underpinnings of attitudes and norms related to specific preventive behaviors in specific populations of interest.

The state psychiatric center as an academically affiliated tertiary care hospital

Conventional wisdom views state psychiatric hospitals as a problem as much as a solution in the fight against mental illness. The legacy of the historic shortcomings of these hospitals--overcrowding, dreary environment, ineffective treatments, understaffing--frames the discussions of their future. The authors argue that a positive, constructive mission and vision for state hospitals is emerging in New York. This vision calls for fewer, smaller, specialized centers redefined as academically affiliated, community based, consumer oriented, tertiary care centers. To transform these centers, a major reengineering is proposed, including centralized treatment, patient and family participation, continuing education for all staff, outcome research, specialization, multi-service campuses, and technology transfer programs. With this transformation, State Psychiatric Centers become partners in efforts to improve the quality of life for people with mental illness throughout society.

Restraint and seclusion: a review of the literature

OBJECTIVE

The author reviewed the literature published since 1972 concerning restraint and seclusion.

METHOD

The review began with a computerized literature search. Further sources were located through citations from articles identified in the original search.

RESULTS

The author synthesized the contents of the articles reviewed using the categories of indications and contraindications; rates of seclusion and restraint as well as demographic, clinical, and environmental factors that affect these rates; effects on patients and staff; implementation; and training.

CONCLUSIONS

The literature on restraint and seclusion supports the following. 1) Seclusion and restraint are basically efficacious in preventing injury and reducing agitation. 2) It is nearly impossible to operate a program for severely symptomatic individuals without some form of seclusion or physical or mechanical restraint. 3) Restraint and seclusion have deleterious physical and psychological effects on patients and staff, and the psychiatric consumer/survivor movement has emphasized these effects. 4) Demographic and clinical factors have limited influence on rates of restraint and seclusion. 5) Local nonclinical factors, such as cultural biases, staff role perceptions, and the attitude of the hospital administration, have a greater influence on rates of restraint and seclusion. 6) Training in prediction and prevention of violence, in self-defense, and in implementation of restraint and/or seclusion is valuable in reducing rates and untoward effects. 7) Studies comparing well-defined training programs have potential usefulness.

Empirical tests of an information-motivation-behavioral skills model of AIDS-preventive behavior with gay men and heterosexual university students

This article contains empirical tests of the information-motivation-behavioral skills (IMB) model of AIDS-preventive behavior (J.D. Fisher & Fisher, 1992; W.A. Fisher & Fisher, 1993a), which has been designed to understand and predict the practice of AIDS-preventive acts. The IMB model holds that AIDS-preventive behavior is a function of individuals' information about AIDS prevention, motivation to engage in AIDS prevention, and behavioral skills for performing the specific acts involved in prevention. The model further assumes that AIDS-prevention information and motivation generally work through AIDS-prevention behavioral skills to influence the initiation and maintenance of AIDS-preventive behavior. Supportive tests of the model, using structural equation modeling techniques, are reported with populations of gay male affinity group members (n = 91) and heterosexual university students (n = 174).

Canadian street youth: correlates of sexual risk-taking activity

The purpose of this study was to develop a national perspective on the sexual activity of street youth in Canada and to determine the correlates of risky sexual behavior according to street youth's link to the street. Five categories of street youth (sex industry workers, heavy drug and/or alcohol users, young offenders, homeless and unemployed) ages 15 to 20 years were recruited in 1988 from 10 Canadian urban centers to participate in a 45-minute structured interview focusing on knowledge and attitudes regarding sexually transmitted diseases (STD)/human immunodeficiency virus, current sexual practices, sexual and STD history, demographic background, alcohol/drug use and relationship with parents and peers. Data from the survey were also compared with findings from more than 15,000 non-street youth adolescents surveyed in the same year with the use of parallel questionnaires. Of 712 street youth surveyed (391 males, mean age 17.3 years; 321 females, mean age 16.8 years), the majority were sexually active (95% males, 93% females) and 22% reported at least one previous STD (16% males, 30% females). The lowest STD rates were in unemployed males (5%) and the highest (68%) in female sex industry workers. STD/human immunodeficiency virus high risk behaviors were frequent with 47% of males and 41% of females having had at least 10 different partners, 73% of males and 75% of females inconsistently using condoms and 22% of males and 24% of females participating in anal intercourse. Even among sex industry workers more than 40% used condoms inconsistently.(ABSTRACT TRUNCATED AT 250 WORDS)

Evaluation of an emergency-procedure teaching laboratory for the development of proficiency in tube thoracostomy

OBJECTIVE

Emergency-procedure laboratories are not a standardized part of the curriculum for emergency medicine residency programs. The authors evaluated the efficacy of an emergency-procedure laboratory to teach medical students and residents the performance of tube thoracostomy.

METHODS

A prospective repeated-measures study of tube thoracostomy placement training was performed in an animal-laboratory setting. Participants were six first-postgraduate-year emergency medicine residents and six fourth-year medical students. Each participant was given a written pretest on tube thoracostomies followed by lectures on tube thoracostomy, venous cutdown, peritoneal lavage, and surgical airway. The procedure laboratory, using an anesthetized canine model (20-25 kg), was then conducted. Tube thoracostomies were timed from skin incision to passage of the tube into the thoracic cavity with subsequent tube fogging. Four attempts per participant were documented. Eighteen days later, an identical procedure laboratory was conducted for the same students including a written posttest identical to the pretest.

RESULTS

The written test scores improved for every participant (p < 0.0001). Mean times for procedures completion improved from 121 sec to 39 sec (p = 0<.001) during the first session and improved from 58 sec to 28 sec (p = 0.005) during the second session. Retention of skills was indicated by significant shortening of the time to completion from the first attempt of the first session to that of the second session (121 sec to 58 sec, p = 0.002).

CONCLUSION

This procedure laboratory, which emphasized skill repetition, led to improvement in procedural speed and retention of tube thoracostomy skills over time. This approach to teaching clinical procedures should be considered for emergency medicine residency programs and for continuing medical education courses that emphasize acquisition of clinical procedural skills.

Intraoperative monitoring of brainstem auditory evoked potentials during resection of a cavernous hemangioma in the fourth ventricle: an indirect monitor of the fifth and seventh nerves

This case demonstrates the use of brainstem auditory evoked potentials (BAEPs) to monitor cranial nerve function. Changes in BAEPs were associated with cranial nerve dysfunction in the trigeminal nerve on the ipsilateral side and the facial nerve on the contralateral side.

Empirically derived consequences: a data-based method for prescribing treatments for destructive behavior

Behavioral treatments are often prescribed on the basis of a functional assessment. However, in a significant number of cases, functional assessment results are equivocal or suggest that internal stimuli are maintaining the behavior. In this investigation, we evaluated an alternative data-based assessment that may be useful in such cases. This assessment was used to identify reinforcers and punishers based on the reinforcement assessment procedure described by Pace, Ivancic, Edwards, Iwata, and Page (1985). We then assessed whether empirically derived reinforcers and punishers could be combined to treat the destructive behaviors of two clients. For both clients, the rates of destructive behavior decreased markedly. The results suggest that empirically derived consequences may be useful in decreasing destructive behavior when a functional assessment is inconclusive or is consistent with the hypothesis that the behavior is stereo-typic and maintained by internal stimuli.

Teaching self-feeding skills to patients with Rett syndrome

Few studies have examined the extent to which functional hand-use may be taught to girls with Rett syndrome after those skills have been lost. In this investigation, five females with classic Rett syndrome were taught to feed themselves using a method of prompting and reinforcement. All patients demonstrated improvements in their self-feeding skills. The results are discussed in terms of the factors that may influence the acquisition of skills in girls with Rett syndrome, and directions for future research and proposed.

Functional communication training with and without extinction and punishment

Functional communication training has been reported to be a promising treatment for severe behavior problems. In this study, functional communication training alone and combined with extinction and/or punishment was evaluated for 4 clients with severe retardation, behavior problems, and communication deficits. The participants were inpatients on a hospital unit for treatment of severe behavior disorders. They received individualized interventions based on functional assessment that included reinforcement of a communication response with the same function as their destructive behavior. Results showed that for some patients, functional communication training was not sufficient to produce clinically significant reductions in destructive behavior, and the combination of training plus punishment produced the largest and most consistent reductions.

Functional assessment and treatment of life-threatening drug ingestion in a dually diagnosed youth

Few data exist on operant mechanisms associated with drug overdose. In this investigation, a functional analysis indicated that life-threatening drug ingestion exhibited by a dually diagnosed youth was maintained by negative reinforcement. An operant intervention, derived from behavioral assessment data, reduced drug ingestion to near-zero levels.

A water-prompting procedure for the treatment of urinary incontinence

Based on clinical observations of a naturally occurring phenomenon, a water-prompting procedure was used to facilitate toilet training with a 9-year-old boy with profound mental retardation. Other frequently used toilet-training procedures were either ineffective or were associated with increased self-injury. The water-prompting treatment package may increase continence by eliciting and reinforcing urination under specific stimulus conditions.

Changing AIDS-risk behavior

This article contains a comprehensive, critical review of the acquired immunodeficiency syndrome (AIDS)-risk-reduction literature on interventions that have targeted risky sexual behavior and intravenous drug use practices. A conceptually based, highly generalizable model for promoting and evaluating AIDS-risk behavior change in any population of interest is then proposed. The model holds that AIDS-risk reduction is a function of people's information about AIDS transmission and prevention, their motivation to reduce AIDS risk, and their behavioral skills for performing the specific acts involved in risk reduction. Supportive tests of this model, using structural equation modeling techniques, are then reported for populations of university students and gay male affinity group members.

A comparison of two approaches for identifying reinforcers for persons with severe and profound disabilities

The development of effective training programs for persons with profound mental retardation remains one of the greatest challenges for behavior analysts working in the field of developmental disabilities. One significant advancement for this population has been the reinforcer assessment procedure developed by Pace, Ivancic, Edwards, Iwata, and Page (1985), which involves repeatedly presenting a variety of stimuli to the client and then measuring approach behaviors to differentiate preferred from nonpreferred stimuli. One potential limitation of this procedure is that some clients consistently approach most or all of the stimuli on each presentation, making it difficult to differentiate among these stimuli. In this study, we used a concurrent operants paradigm to compare the Pace et al. (1985) procedure with a modified procedure wherein clients were presented with two stimuli simultaneously and were given access only to the first stimulus approached. The results revealed that this forced-choice stimulus preference assessment resulted in greater differentiation among stimuli and better predicted which stimuli would result in higher levels of responding when presented contingently in a concurrent operants paradigm.

Educational achievement in non-verbal children: are they learning disabled?

From a data-base of all nonspeaking children in North Dakota we analyzed the data on those children functioning above the retarded range to determine the prevalence of children meeting the main inclusion criteria for learning disabilities (LD), a severe discrepancy between IQ and achievement. The mean IQ for this group of 38 nonspeaking, nonretarded children of 104.0 was significantly higher than IQ equivalent scores in the academic subjects of reading (66.4), math (70.4), written language (65.2), and spelling (71.2). Using a stringent criterion for an IQ-achievement discrepancy of 2 standard deviations, 27 of 38 (71%) met this criterion in at least one subject. Academic subjects dependent upon higher linguistic functioning, written language and reading, were more affected than spelling and math. While the vast majority (73%) of these 38 children were deaf, the prevalence of IQ-achievement discrepancies was also found in 57% of the nonspeaking children without hearing impairments. These data suggest the common practice of excluding a diagnosis of a learning disability in a deaf child on the basis of the child's hearing impairment may not be appropriate. Further research is needed on the role of speech in academic achievement.

Behavioral treatment of sleep dysfunction in patients with the Rett syndrome

Aberrant sleep patterns are commonly experienced by girls with the Rett syndrome. In this investigation, the problematic sleep of three girls with the Rett syndrome was regulated using a bedtime fading procedure with response cost. The treatment involved systematically delaying the bedtime and utilized a response cost component, removing the child from bed for one hour, when the child did not experience short latency to sleep onset. Daytime sleep was interrupted, except during regularly scheduled naps. A fading procedure was then successfully utilized to advance the bedtimes. This treatment resulted in more regular sleep patterns for the girls by increasing appropriate nighttime sleep, reducing inappropriate daytime sleep and reducing problematic nighttime behaviors (e.g., night wakings). These preliminary findings are important because they suggest that the dysfunctional sleep patterns of girls with the Rett syndrome may be amenable to behavioral treatments.

Reinforcement of incontinent stools in the treatment of encopresis

In this paper, fecal incontinence and constipation were treated in two mentally retarded individuals using a novel intervention wherein incontinent stools were first rewarded in order to increase the frequency of bowel movements. This intervention was implemented only after more traditional pediatric and behavioral treatments were unsuccessful. The reinforcement of incontinent stools procedure resulted in an increase in both the frequency and the number of continent stools for both individuals. Hypotheses regarding the failure of previous treatments and the success of the current treatment are discussed as well as directions for future research.

A faded bedtime with response cost protocol for treatment of multiple sleep problems in children

The sleep-wake cycles of 4 developmentally delayed individuals with longstanding severe sleep disturbances were regulated using a faded bedtime procedure with response cost. Bedtimes were systematically delayed for each individual, thus increasing the probability of short latency to sleep onset. The response cost component, consisting of removing the individual from bed for 1 hour, was implemented when an individual did not experience short latency to sleep onset. A fading procedure was then applied successfully to advance the bedtimes and to gradually increase durations of sleep. Specifically, all 4 individuals had decreased amounts of nighttime sleep that increased following treatment. Two of the 4 individuals showed excessive daytime sleep that decreased following treatment. Three of the 4 individuals experienced decreases in night wakings following treatment. Both environmental and biological manipulations of the sleep-wake cycle are hypothesized as mechanisms of treatment. The relative advantages of this procedure over other procedures for the treatment of pediatric sleep disorders are discussed, as are directions for future research.

Pulmonary complications of combination therapy with cyclophosphamide and prednisone

Oral cyclophosphamide and prednisone are standard treatment for some neoplasms and necrotizing systemic vasculitis and are advocated with increasing frequency for idiopathic interstitial lung disease. During a 15-month period, we observed four cases of acute respiratory failure from Pneumocystis carinii pneumonia (PCP) in patients treated with oral cyclophosphamide and prednisone. One patient each had polyarteritis nodosa, Wegener's granulomatosis, bronchiolitis obliterans with organizing pneumonia, and chronic lymphocytic leukemia with red blood cell aplasia. Hypoalbuminemia (serum albumin level less than 3.0 g/dl) and daily therapy were associated with increased risk for development of PCP (p less than 0.05). None of the patients had leukopenia (less than 3,500/cu mm) or neutropenia (less than 1,000/cumm) at diagnosis. All were negative for the human immunodeficiency virus. Patients receiving oral cyclophosphamide and prednisone may be at higher or increasing risk for PCP. A high index of suspicion and aggressive evaluation for opportunistic infection are needed in these patients; consideration for trimethoprim-sulfamethoxazole prophylaxis and development of more quantitative measures of immunosuppression are needed.
