["I will never forget it!": the experience of a woman with induced abortion].

Based on the symbolic interactionist approach, we aimed to verify the meanings attributed to induced abortion by women who adopted such behavior as well as to analyze the impact of the experience on their self-image. The results point out the contradiction in women's discourse when they evaluate the experience, and the emotional negative reactions they had developed: remorse/guilty conscience, regret, feeling of grief, and mainly guilt, which, according to their accounts, they will carry for the rest of their lives.

Young drivers' decision making and safety belt use.

Past research in safety belt use has primarily focused on describing the relationship between drivers' demographic characteristics and safety belt use. This study compared the impact of situational factors (the direction of collision, the type of road, and the presence of an airbag system), demographic factors, and constructs (criteria) elicited from subjects regarding safety belt use. Based on the results obtained, a conceptual model was developed. The model indicated that drivers' decision-making process when judging the level of accident risk and usefulness of safety belts differs from those that determine actual behavior. Perceived risk was related to road type, perceived consequences of an accident, perceived usefulness of safety belts, self responsibility, the time available for the driver to warn the other driver, dangerous behavior, and gender. These variables showed that people were able to rationally judge the risk. Despite the fact that people judge behavior in what appeared to be a rational manner, risk perception was not a good predictor of belt use. Belt use was mainly influenced by individual factors such as gender, grade point average (GPA), and age. Other factors impacting safety belt use included the perceived frequency of an accident and the S.D. of perceived usefulness of safety belts.

Factors related to seroconversion among homo- and bisexual men after attending a risk-reduction educational session.

Thirteen homosexual men, volunteers in a study of the natural history of HIV, who seroconverted to HIV after participating in an educational program on HIV prevention, were interviewed about the circumstances leading to their seroconversion. Six men had participated in unprotected anal intercourse with at least one partner whom they believed was HIV-negative. Four men attributed their conversion to mental health problems or to drug and alcohol use. Two men's seroconversions could not be ascertained and one man attributed seroconversion to a condom break. Most men who had learned how to avoid infection, and had successfully done so for a time, had knowingly engaged in unsafe behaviors because of strong emotional responses to certain partners or because of mental health or drug and alcohol-related problems. Skills training for dealing with partners who pressure men to behave unsafely is needed, as is mental health and drug and alcohol counseling for men at risk for HIV infection.

Gay-male couples who adopt: challenging historical and contemporary social trends toward becoming a family.

TOPIC: Gay-male couples who adopt children face ongoing challenges that stem from both historical and contemporary social issues. PURPOSE: To examine and identify key points and guidance for advanced practice psychiatric mental health nurses regarding multicultural awareness involved in counseling gay-male couples who explore or exercise their right to adopt and raise children. SOURCES: A comprehensive review of the extant scientific literature and public media, clinical anecdotes, therapeutic experiences, and an examination of Healthy People 2010 as it relates to how community health is profoundly affected by the collective beliefs, attitudes, and behaviors of everyone who lives in the community. CONCLUSIONS: Heterosexism, homophobic fears, oppression, and the general stigma that surround gay-male couples who choose to adopt children are a few of the relevant contemporary issues and community beliefs for which advanced practice psychiatric mental health nurses need to assess, explore, and intervene.

Sucrose ingestion normalizes central expression of corticotropin-releasing-factor messenger ribonucleic acid and energy balance in adrenalectomized rats: a glucocorticoid-metabolic-brain axis?

Both CRF and norepinephrine (NE) inhibit food intake and stimulate ACTH secretion and sympathetic outflow. CRF also increases anxiety; NE increases attention and cortical arousal. Adrenalectomy (ADX) changes CRF and NE activity in brain, increases ACTH secretion and sympathetic outflow and reduces food intake and weight gain; all of these effects are corrected by administration of adrenal steroids. Unexpectedly, we recently found that ADX rats drinking sucrose, but not saccharin, also have normal caloric intake, metabolism, and ACTH. Here, we show that ADX (but not sham-ADX) rats prefer to consume significantly more sucrose than saccharin. Voluntary ingestion of sucrose restores CRF and dopamine-beta-hydroxylase messenger RNA expression in brain, food intake, and caloric efficiency and fat deposition, circulating triglyceride, leptin, and insulin to normal. Our results suggest that the brains of ADX rats, cued by sucrose energy (but not by nonnutritive saccharin) maintain normal activity in systems that regulate neuroendocrine (hypothalamic-pituitary-adrenal), behavioral (feeding), and metabolic functions (fat deposition). We conclude that because sucrose ingestion, like glucocorticoid replacement, normalizes energetic and neuromodulatory effects of ADX, many of the actions of the steroids on the central nervous system under basal conditions may be indirect and mediated by signals that result from the metabolic effects of adrenal steroids.

Medicaid enrollee switching among managed care plans.

This case-study (n=41,969) of voluntary switching among Mecklenburg County, North Carolina Medicaid managed care plans showed a low switching rate of 14.5 per 100 member-years over 33 months, or 5.3 averaged annually. Population, plan and plan characteristics, claims and telephone survey data were examined to better understand this important behavioral measure. Switching in Medicaid managed care, which is little studied, is contrasted with the extensive literature on middle class switching. Policy implications included the suitability of Medicaid populations for managed care and the need for more research on switching and disenrollment and the Medicaid innovation of neutral health benefits advising.

The role of objective personality inventories in suicide risk assessment: an evaluation and proposal.

Objective personality assessment instruments offer a comparatively underutilized source of clinical data in attempts to evaluate and predict risk for suicide. In contrast to focal suicide risk measures, global personality inventories may be useful in identification of long-standing styles that predispose persons to eventual suicidal behavior. This article reviews the empirical literature regarding the efficacy of established personality inventories in predicting suicidality. The authors offer several recommendations for future research with these measures and conclude that such objective personality instruments offer only marginal utility as sources of clinical information in comprehensive suicide risk evaluations. Personality inventories may offer greatest utility in long-term assessment of suicide risk.

Eager sellers and stony buyers: understanding the psychology of new-product adoption.

Companies that introduce new innovations are the most likely to flourish, so they spend billions of dollars making better products. But studies show that new innovations fail at a staggering rate. While many blame these misses on lackluster products, the reality isn't so simple. The goods that consumers dismiss often do offer improvements over existing ones. So why don't people purchase them? And why do companies keep peddling products that buyers are likely to reject? The answer, says the author, can be found in the brain. New products force consumers to change their behavior, and that has a psychological cost. Many products fail because people irrationally over-value the benefits of the goods they own over those they don't possess. Executives, meanwhile, overvalue their own innovations. This leads to a serious clash. Studies show, in fact, that there is a mismatch of nine to one, or 9x, between what innovators think consumers want and what consumers truly desire. Fortunately, companies can overcome this disconnect. To start, they can determine where their products fall in a matrix with four categories: easy sells, sure failures, long hauls, and smash hits. Each has a different ratio of product improvement to change required from the consumer. Once businesses know where their products fit into this grid, they can manage the resistance to change. For some innovations, major behavior change is a given. In those cases, companies can either wait for consumers to warm to the product, make the improvement so great that buyers get past their apprehension, or try to eliminate the incumbent product. Firms can also try to minimize buyer resistance by making products that are compatible with incumbent goods, seeking out those who are not yet users of the existing product, or finding true believers.

Religious affiliations and consumer behavior: an examination of hospitals.

The author re-examines the conclusions of an earlier study which contends that religious affiliation of a hospital is important in influencing hospital selection and contributes to overall patient satisfaction. In this new survey, patients ranked religious affiliation low in importance when choosing among hospitals. However, hospitals of a particular religious affiliation were more likely to be recalled, preferred, and selected by people of the same religious affiliation. Furthermore, on quality-of-care measures, religious affiliation influenced hospital evaluations.

[Tactical behavior of rats when choosing among negative stimuli: pain or exposure to an electromagnetic field].

A new experimental model of two conflicting motives has been developed and tested on rats. The motives are to escape painful stimulation and subsequent microwave irradiation at a dose rate of 500 mWt/cm2 under normal conditions and disturbed thermal regulation due to gamma irradiation of the head. It is found that microwave effects cannot be entirely attributed to the body temperature gradient.

The reinforcing effects of acetaldehyde in the posterior ventral tegmental area of alcohol-preferring rats.

Acetaldehyde (ACD), the first metabolite of ethanol, is a biologically active compound, which may mediate some of the reinforcing, behavioral and neurotoxic effects of ethanol. The objective of this study was to test the hypothesis that ACD is reinforcing within the mesolimbic system. The intracranial self-administration (ICSA) technique was employed to determine whether ACD was reinforcing in the posterior ventral tegmental area (VTA), a site that supports the reinforcing actions of ethanol. Adult female alcohol-preferring (P) rats were implanted with guide cannulae aimed at the posterior VTA. Subjects were placed in two-lever operant chambers 7-10 days after surgery. Responding on the "active lever" on a fixed ratio 1 (FR1) schedule of reinforcement caused the delivery of 100 nl of infusate, whereas responses on the "inactive lever" were without consequences. Rats were assigned to one of five groups that self-administered either artificial cerebrospinal fluid (aCSF) throughout all eight sessions (4 h in duration) or 3- and 6-, 11- and 23-, 45- and 90- or 180- and 360-microM ACD for the eight sessions, with the lower concentration of ACD given for the initial four sessions and the higher concentration of ACD given for the last four sessions. A second experiment examined the acquisition (first four sessions), extinction (aCSF in sessions 5 and 6) and reinstatement using 90-microM ACD. A third experiment examined the effects of extending the time-out period (from 5 to 55 s) on the number and pattern of infusions of 23-microM ACD. Adult P rats readily self-administered 6-90-microM ACD and discriminated between the active and inactive levers. Furthermore, rats self-administering 90-microM ACD also demonstrated extinction behavior when aCSF was substituted for ACD and gradually reinstated active lever responding when ACD was reintroduced. P rats maintained similar numbers of infusions and infusion patterns under both time-out schedules. Overall, the data indicate that ACD is a potent reinforcer within the posterior VTA of the P rat.

Behavioral dynamics of steering, obstacle avoidance, and route selection.

The authors investigated the dynamics of steering and obstacle avoidance, with the aim of predicting routes through complex scenes. Participants walked in a virtual environment toward a goal (Experiment 1) and around an obstacle (Experiment 2) whose initial angle and distance varied. Goals and obstacles behave as attractors and repellers of heading, respectively, whose strengths depend on distance. The observed behavior was modeled as a dynamical system in which angular acceleration is a function of goal and obstacle angle and distance. By linearly combining terms for goals and obstacles, one could predict whether participants adopt a route to the left or right of an obstacle to reach a go (Experiment 3). Route selection may emerge from on-line steering dynamics, making explicit path planning unnecessary.

A comparison of verbal and tangible stimulus preference assessments.

Tangible preference assessments were compared with verbal preference assessments for 6 individuals with mental retardation, behavior disorders, or both. In the tangible assessment, items were placed in front of the participant. In the verbal assessment, participants were asked, "Do you want X or Y?" and the items were not present. The two assessments yielded similar high-preference items for 4 of the 6 participants. The verbal assessment was typically completed in less time than the tangible assessment.

Toward an empirical method for identifying matched stimulation for automatically reinforced behavior: a preliminary investigation.

The effects of noncontingent matched stimulation (NMS) and response blocking on a boy's stereotypic behavior were evaluated using a multiple schedule that contained three 15-min components (preintervention, intervention, and postintervention). Results showed that stereotypy was always higher after response blocking than before response blocking and was always lower after NMS than before NMS. These results suggest that response blocking may have produced deprivation for the product of stereotypy and that NMS may have provided stimulation that was similar to the product of stereotypy.

Preferred body type of fitness instructors among university students in exercise classes.

This study examined the relationship between participants' physique anxiety, eating behaviors, somatotype, and the preferred qualifications and body type of a fitness instructor. Subjects were 171 students attending fitness classes at a university. Analysis indicated that the women preferred a thinner fitness instructor than men and that enthusiasm, motivation, and being physically fit were considered the most important characteristics overall. No significant racial differences in key variables were found.

Identifying new patient prospects: efficacy of usage segmentation. For some health care services, usage-based segmentation schemes can be wasteful and ineffective.

Even though there is intuitive appeal in identifying the user profile for a given service and then targeting similar nonusers, this approach can be very misleading when marketing health care services with low market penetration. If usage segmentation is employed without checking other indicators of latent demand and perceived barriers to use, significant misallocation of marketing resources is likely to occur. Confidentiality and embarrassment can be significant barriers to use by segments that are excellent patient prospects. In this study of mental and behavioral care, females and non-whites were found to be more concerned with confidentiality than were members of the user group. Lack of awareness can be a much bigger impediment to adoption than negative attitudes. Health care marketers need to design communications that not only increase awareness and familiarity for services with low market penetration, but also address other issues of concern to highly receptive segments.

Voluntary consumption of beverage alcohol by vervet monkeys: population screening, descriptive behavior and biochemical measures.

Seventeen percent of 196 feral vervet monkeys (Cercopithecus aethiops) spontaneously drank appreciable quantities of beverage alcohol in 3% sucrose in preference to 3% sucrose alone. Ethanol consumption increased over time, as did the concentration of ethanol tolerated. Willingness to select ethanol was stable over a three-year period, as measured by periodic retesting. Individual patterns of drinking and behavioral responses to ethanol were quite variable. Upon occasion, some animals drank to ataxia and unconsciousness; signs of withdrawal, including tremulousness, pacing, irritability and increased aggression, followed the abrupt discontinuation of ethanol availability. A variety of changes in social interaction, including increased orientation to external stimulus, increased incidence of stereotyped aggression and of other stereotyped behaviors and decreased frequency of affiliative behaviors were observed during ethanol periods, as compared to baseline scoring periods. In a small number of alcohol-preferring animals, CSF amine metabolites (5-hydroxyindoleacetic acid and homovanillic acid) were raised by drinking alcohol. These studies suggest that the alcohol-selecting vervet monkey may be complementary to established primate models of alcoholism.

Cancer information scanning and seeking behavior is associated with knowledge, lifestyle choices, and screening.

Previous research on cancer information focused on active seeking, neglecting information gathered through routine media use or conversation ("scanning"). It is hypothesized that both scanning and active seeking influence knowledge, prevention, and screening decisions. This study uses Health Information National Trends Survey (HINTS, 2003) data to describe cancer-related scanning and seeking behavior (SSB) and assess its relationship with knowledge, lifestyle behavior, and screening. Scanning was operationalized as the amount of attention paid to health topics, and seeking was defined as looking for cancer information in the past year. The resulting typology included 41% low-scan/no-seekers; 30% high-scan/no-seekers; 10% low-scan/seekers, and 19% high-scan/seekers. Both scanning and seeking were significantly associated with knowledge about cancer (B=.36; B=.34) and lifestyle choices that may prevent cancer (B=.15; B=.16) in multivariate analyses. Both scanning and seeking were associated with colonoscopy (OR = 1.38, for scanning and OR=1.44, for seeking) and with prostate cancer screening (OR=4.53, scanning; OR=10.01, seeking). Scanning was significantly associated with recent mammography (OR=1.46), but seeking was not. Individuals who scan or seek cancer information are those who acquire knowledge, adopt healthy lifestyle behaviors, and get screened for cancer. Causal claims about these associations await further research.
