Predictors of sexual behavior change among men requesting their HIV-1 antibody status: the Chicago MACS/CCS cohort of homosexual/bisexual men, 1985-1986.

It has been proposed that human immunodeficiency virus (HIV) antibody testing and counseling are effective means of altering sexual behavior among individuals at risk of HIV infection and transmission. However, the evidence supporting this hypothesis is inconclusive. This study examines the factors associated with sexual behavior change among a group of participants in the Chicago MACS/Coping and Change Study (CMACS/CCS) who requested their HIV antibody status when they were first given the opportunity, between 1985 and 1986. A set of demographic and psychosocial predictors were tested in association with 4 possible outcome patterns of sexual behavior change during the time of antibody status disclosure. For comparative purposes, a randomly selected sample of men who did not request disclosure of their HIV antibody status was analyzed. The results revealed that, among the 177 individuals who requested disclosure, the group experiencing an adverse sexual behavior change (i.e., from low risk before disclosure to high risk after disclosure) reported, before disclosure, the highest level of mental distress and denial-fatalism coping strategies and had the lowest levels of social support compared with other groups being analyzed. The psychosocial predictor most strongly associated with adverse sexual behavior change appears to be the use of denial-fatalism coping. Such an association was not found among the nondisclosed comparison group. These results suggest that a subgroup of at-risk, well-educated, white men, with overall high knowledge of HIV transmission, may not benefit from current HIV counseling and testing. Such men at risk for adverse behavioral outcomes might be identified in advance of HIV-1 antibody testing by their psychosocial profile, and thus appropriate counseling resources could be targeted to them.

Behavior-change action plans in primary care: a feasibility study of clinicians.

PURPOSE: Collaborative goal-setting--with clinician and patient together deciding on concrete behavior-change goals-may be more effective in encouraging healthy behaviors than traditional clinician-directed advice. This study explores whether it is feasible for clinicians to engage patients with coronary heart disease (CHD) risk factors in collaborative goal-setting and concrete action planning during the primary care visit. METHODS: Primary care clinicians were trained in goal-setting and action planning techniques and asked to conduct action plan discussions with study patients during medical visits. Clinicians' experiences were documented through post-visit surveys and with questionnaires and semistructured interviews at the end of the study. RESULTS: Forty-three clinicians and 274 patients with CHD risk factors participated in the study; 83% of the patient encounters resulted in a behavior-change action plan. Goal-setting discussions lasted an average of 6.9 minutes. Clinicians rated 75% of the discussions as equally or more satisfying than previous behavior-change discussions, and identified time constraints as the most important barrier to adopting the goal-setting process. CONCLUSIONS: Collaborative goal-setting between clinicians and patients for improved health behaviors is viewed favorably by clinicians in primary care. Time constraints could be addressed by delegating goal-setting to other caregivers.

Behavioral changes in rat following perinatal exposure to ethanol.

Behavioral changes following pre- and postnatal ethanol administration were examined in rat pups of various ages. A significant increase in locomotor activity occurred at all ages (16, 22 and 30 days) examined. Nose poking activity in 22-day-old pups and standing activity in 30-day-old pups were also significantly higher following perinatal ethanol exposure. No significant change in grooming behavior was observed. The overactivity in rat pups following perinatal ethanol exposure is consistent with the frequently observed hyperactivity in fetal alcohol syndrome children.

What front-line CBO staff can tell us about culturally anchored theories of behavior change in HIV prevention for Asian/Pacific Islanders.

Few rigorously tested primary prevention programs have been developed to prevent HIV infection among immigrant communities in the United States. This is in part because of the lack of culturally specific behavioral theories that can inform HIV prevention for immigrant communities in the United States. This article aims to develop such theories for a population--Asian/Pacific Islanders (A/PIs) immigrant communities--who have been overlooked in theory development and program evaluation. Frontline community-based organization (CBO) peer educators, an underutilized source of expertise regarding cultural factors specific to HIV infection among A/PI communities, are the sample of study Asian/Pacific Islander peer educators working at an urban AIDS service organization devoted to health promotion for this population; (N = 35). They were interviewed to examine (1) detailed narratives describing instances of behavior change and (2) culturally anchored theories of behavior change which the narratives imply. Theories of the influence of positive cultural symbols on the taboo of HIV/AIDS, moderators of the effectiveness of social network influences on behavior change, and setting- and community-level processes predicting HIV risk behavior were implicit in the peer educators' narratives. Implications for future research, methodology and prevention practice are discussed.

[Behavioral changes of rats under rotation stimulation].

OBJECTIVE: To assess the specification and efficiency of rotation sickness indices by monitoring changes of behaviors in rats under rotation stimulation. METHOD: SD rats were stimulated by Crampton model with different time courses. Pica or kaolin consumption (KC), conditioned taste aversion (CTA) or saccharine water ingestion (SWI), 2 h food ingestion (2hFI), and open-field test (OFT) scores were observed. RESULT: Apparent changes of the four indices were observed after rotation stimulation. SWI, OFT scores and 2hFI decreased exponentially with increase of duration of the motion stimulation. KC increased linearly with the increase of time within 12 h stimulation. After 18 h stimulation, KC decreased to a level even lower than that after 6 or 12 h stimulation. The adjusted correlation between changes of the indices and duration of stimulation within 12 h are: 0.94 for KC, 0.54 for SWI, 0.44 for 2hFI and 0.34 for OFT. The maximum efficiency of the four indices appeared at 6-hour stimulation: 70% for KC, 90% for SWI, 80% for 2hFI and 95% for OFT. CONCLUSION: It is found that pica and CTA were more specific than the other indices. They may serve as primary indices and can be combined with the secondary indices such as 2hFI or OFT. Six hours is the optimal duration of stimulation by Crampton model for rotation sickness studies.

Course of behavioral change in autism: a retrospective study of high-IQ adolescents and adults.

OBJECTIVE: The course of behavioral change in autistic behaviors has received little attention in previous research but is a potentially important parameter for study in autism. METHOD: Autistic behaviors were systematically examined in 38 high-IQ adolescent and adult autistic individuals at their current age (13 through 28 years) and retrospectively at age 5 years using a standardized interview for autism. RESULTS: Significant change over time in autistic behaviors, generally in the direction of improvement, was detected. The proportion of subjects showing improvement in communication and social behaviors was found to be significantly higher than the proportion showing improvement in ritualistic/repetitive behaviors. Five of 38 subjects who met DSM-IV criteria for autistic disorder at age 5 years no longer met criteria at their current age, although all five continued to have substantial impairment. CONCLUSIONS: The study of patterns of behavioral change over time in autism has practical implications for both diagnosis and prognosis as well as potential importance in defining biologically meaningful subgroups and clarifying fundamental mechanisms underlying this disorder.

Effect of antioxidant N-acetyl-L-cysteine on behavioral changes and neurotoxicity in rats after administration of methamphetamine.

Several lines of evidence suggest that oxidative stress may play a role in the behavioral changes and neurotoxicity in rats after administration of methamphetamine (MAP). N-acetyl-L-cysteine (NAC) is a precursor of glutathione, and it also exerts as an antioxidant. In this study, we investigated the effects of NAC on the behavioral changes (hyperlocomotion and development of sensitization) and neurotoxicity in male Wistar rats after administration of MAP. Pretreatment with NAC (30, 100 or 300 mg/kg, i.p.) attenuated significantly hyperlocomotion in rats induced by a single administration of MAP (2 mg/kg, i.p.), in a dose-dependent manner. Furthermore, pretreatment with NAC (100 mg/kg, i.p., 15 min before MAP injection, once daily for 5 consecutive days) blocked significantly the development of behavioral sensitization in rats after repeated administration of MAP (2 mg/kg, once daily for 5 consecutive days), whereas the behaviors in rats after repeated administration of NAC plus saline groups were not different from those of control (vehicle plus saline) groups. One week after administration of MAP (7.5 mg/kg x 4, 2-h intervals), levels of dopamine (DA) in rat striatum were significantly decreased as compared with control groups. Pretreatment with NAC (1, 3, 10 or 30 mg/kg, i.p., 30 min before each MAP injection) attenuated significantly the MAP-induced reduction of DA in rat striatum, in a dose-dependent manner. These results suggest that NAC could prevent the behavioral changes (acute hyperlocomotion and development of behavioral sensitization) in rats and neurotoxicity in rat striatum after administration of MAP, and that NAC would be a useful drug for treatment of several symptoms associated with MAP abuse.

Patient education for behavior change: help from the Transtheoretical and Harm Reduction models.

Promoting healthy behaviors at all levels of prevention is an important component of nursing care in the HIV epidemic. This paper explores two models that can be used to support behavior change efforts: the Transtheoretical Model, which describes stages in the change process, and the Harm Reduction Model, which offers an incremental approach to helping clients move toward safer and healthier habits. A review of the literature shows that these holistic and caring models can be combined effectively to assist clients who are dealing with HIV-related issues. The resulting theory-based approach can help nurses maintain consistency and direction in educational interventions for behavior change.

Healthy aging demonstration project: nurse coaching for behavior change in older adults.

The Healthy Aging Project (HAP) tested nurse coaching as a method to support healthy behavior change in older adults. The sample included 111 individuals randomized to a nurse coaching group or usual-care control group. Participants in the intervention group chose the health behaviors they wanted to change and received coaching by nurses in a single in-person session followed by telephone calls or email contact for 6 months. Nurses were trained in motivational interviewing (MI). The intervention group had significantly less illness intrusiveness and health distress than the control group at 6 months, although it is not known whether these health outcomes resulted from behavior changes. This clinical demonstration project showed that nurse-delivered MI, primarily using the telephone and email, is a feasible method to discuss behavioral change with older adults. However, future clinical trials will be needed to evaluate the efficacy of nurse-delivered MI on actual behavioral changes in older adults.

Toward a socioethical approach to behavior change.

Infection control professionals have traditionally relied on didacticism to promote behavior change among health care workers, but this approach yields disappointing results in a postmodern era of social fragmentation and intellectual ambiguity. We define a socioethical approach to behavior change and propose its implementation in 4 movements: from individualism to community, from rationality to rhetoric, from productivity to praxis, and from monologue to dialogue.

Health behavior changes in the United States, the United Kingdom, and France.

OBJECTIVE: To determine changes in health behaviors in the United States, the United Kingdom, and France over the previous two years. DESIGN: Cross-sectional survey of nationally representative samples. SETTING/PARTICIPANTS: Surveys conducted between June and November 1988 on persons aged 16 to 50 years in the United States (n = 1,940), the United Kingdom (n = 1,833), and France (n = 2,294) regarding health behaviors, attitudes toward health, and changes in health practices during the previous two years. MEASUREMENTS AND MAIN RESULTS: Using Bonferroni's adjustment for multiple comparisons, residents of the United States had significantly (p < 0.05) higher Quetelet indices and reported higher egg and red meat consumption, but had lower alcohol consumption, than did residents of either the United Kingdom or France. Americans were also significantly more likely to report attitudes accepting personal responsibility for their health and much more often endorsed the role of health behaviors (e.g., exercise) for decreasing the risk of cardiovascular disease. Changes in health behavior over two years were consistently more likely in the United States for weight loss, decreased alcohol consumption, decreased red meat and egg consumption, and increased exercise. Americans were also much more likely to have changed at least three health behaviors in the previous two years (United States 41.5%, United Kingdom 25.5%, France 13.8%, p < 0.002). A multivariate linear model confirmed the high likelihood of health behavior changes in the United States compared with the United Kingdom or France. CONCLUSIONS: The findings confirm that changes in health behaviors are continuing to occur in the United States, but remain comparatively modest in the United Kingdom and France. These international variations in health behaviors parallel differential declines in mortality rates in ischemic heart disease.

Self-care motivation: a model for primary preventive oral health behavior change.

Attempts to promote compliance of children with preventive health practices are most successful when strategies for motivating self-care behavior change address the physical, cognitive, and affective components of individuals. This study evaluated the effectiveness of using a Self-Care Motivation Model and curriculum to promote oral health and hygiene behavior change among 92 third grade students randomly selected according to homeroom assignments in five Gloucester, Mass., public schools. Student gingival health and oral hygiene measures were obtained two weeks prior to, and two weeks, three months, and one year after educational sessions. Group one, comprised of mid-high socioeconomic status family students, served as an oral examination control. Groups two-five received educational sessions designed to teach students various aspects of oral health. Significant improvements (p less than .001) in gingival health and dental plaque scores were observed in all experimental groups for up to three months. During a period of three months to one year, mean group scores returned to baseline and worsened for all groups except group five, the lowest socioeconomic family status group and the only group receiving the full series of self-care motivation curriculum sessions. Experimental group teachers reported that most children responded favorably to the program, and specific attitude and behavior changes were observed in many children. Further research evaluating the efficacy of using this self-care motivation model in primary preventive health education programs is indicated.

Time course of behavioral changes following basal forebrain cholinergic damage in rats: Environmental enrichment as a therapeutic intervention.

The present experiment was designed to study changes in behavior following immunolesioning of the basal forebrain cholinergic system. Rats were lesioned at 3 months of age by injection of the 192 IgG-saporin immunotoxin into the medial septum area and the nucleus basalis magnocellularis, and then tested at different times after surgery (from days 7-500) on a range of behavioral tests, administered in the following order: a nonmatching-to-position task in a T-maze, an object-recognition task, an object-location task, and an open-field activity test. The results revealed a two-way interaction between post-lesion behavioral testing time and memory demands. In the nonmatching-to-position task, memory deficits appeared quite rapidly after surgery, i.e. at a post-lesion time as short as 1 month. In the object-recognition test, memory impairments appeared only when rats were tested at late post-lesion times (starting at 15 months), whereas in the object-location task deficits were apparent at early post-lesion times (starting from 2 months). Taking the post-operative time into account, one can hypothesize that at the shortest post-lesion times, behavioral deficits are due to pure cholinergic depletion, while as the post-lesion time increases, one can speculate the occurrence of a non-cholinergic system decompensation process and/or a gradual degeneration process affecting other neuronal systems that may contribute to mnemonic impairments. Interestingly, when middle-aged rats were housed in an enriched environment, 192 IgG-saporin-lesioned rats performed better than standard-lesioned rats on both the nonmatching-to-position and the object-recognition tests. Environment enrichment had significant beneficial effects in 192 IgG-saporin-lesioned rats, suggesting that lesioned rats at late post-lesion times (over 1 year) still have appreciable cognitive plasticity.

Social problem solving training for African Americans: effects on dietary problem solving skill and DASH diet-related behavior change.

OBJECTIVE: Hypertension continues to take its toll on millions of African Americans. Adhering to an eating plan called Dietary Approaches to Stop Hypertension (DASH) can significantly lower blood pressure. This study examined whether problem solving training in addition to education on DASH is more effective than education alone to help African Americans in an urban community college setting solve their own dietary problems and change eating behaviors that could affect blood pressure. METHODS: A randomized, two groups, multiple post-test design was used. All participants (N=78, 59% female) completed a Problem Solving Instrument immediately post-intervention and a follow-up Telephone Interview 2 weeks later. RESULTS: Fewer than half had normal blood pressure on screening. The Experimental Group identified and implemented significantly higher quality solutions to the second of their two problems than the Control Group. The intervention effect was the greatest for participants with blood pressure screenings above normal. CONCLUSION: Problem solving training combined with nutrition information may help African Americans to deal more effectively with dietary problems especially when the problems are complex or less well-defined. PRACTICE IMPLICATIONS: Dietary interventions that include a focus on everyday problem solving as well as knowledge acquisition can be developed in clinical, community health, school, and worksite settings.

Community health behavior change through computer network health promotion: preliminary findings from Stanford Health-Net.

Computer-based health education has been employed in many settings. However, data on resultant behavior change are lacking. A randomized, controlled, prospective study was performed to test the efficacy of Stanford Health-Net (Stanford, CA, U.S.A.) in changing community health behaviors. Graduate and undergraduate students (N = 1003) were randomly assigned to treatment and control conditions. The treatment group received access to Health-Net, a health promotion computer network emphasizing specific self-care and preventive strategies. Over a 4-month intervention period, 26% of the treatment group used Health-Net an average of 6.4 times each (range 1-97). The most commonly cited reasons for use were curiosity, general health education, evaluation of current symptoms and anonymity of information. Users rated Health-Net favorably. The most commonly reported reasons for non-use were related to lack of health problems, limited time and lack of access to computer facilities. The mean number of ambulatory medical visits decreased 22.5% more in the treatment group than in the control group (P less than 0.05), while hospitalizations did not differ significantly between groups. In addition, perceived self-efficacy for preventing the acquisition of a sexually transmitted disease (STD) and herpes increased 577% (P less than 0.05) and 261% (P less than 0.01) more, respectively, in the treatment group than in the control group. These findings suggest that access to Stanford Health-Net can result in significant health behavior change. The advantages of the network approach make it a potential model for other communities.
