Psychobiology and psychiatric nursing: a philosophical matrix.

Over the past several years, conceptualizations of the mind have been challenged by a knowledge explosion in the psychobiological sciences. Such new knowledge continues to fuel a paradigm shift in psychiatry away from traditional psychodynamic models of the mind and toward ones balanced with a psychobiological dimension. The combination of psychodynamic and psychobiological fields of knowledge offers an opportunity for a holistic perspective on the human experience. Psychiatric nursing faces the challenge of integrating this new knowledge for the enrichment of its practice. To accomplish this complex task, issues need to be addressed in many areas critical to psychiatric nursing. Three areas are discussed in this article and include philosophy, communication of philosophy, and testing of philosophy. This article concludes with a discussion of some potential mechanisms to deal with the tensions generated by a paradigm shift in psychiatric nursing.

When and why do people avoid unknown probabilities in decisions under uncertainty? Testing some predictions from optimal foraging theory.

When given a choice between two otherwise equivalent options - one in which the probability information is stated and another in which it is missing - most people avoid the option with missing probability information (Camerer & Weber, 1992). This robust, frequently replicated tendency is known as the ambiguity effect. It is unclear, however, why the ambiguity effect occurs. Experiments 1 and 2, which separated effects of the comparison process from those related to missing probability information, demonstrate that the ambiguity effect is elicited by missing probabilities rather than by comparison of options. Experiments 3 and 4 test predictions drawn from the literature on behavioral ecology. It is suggested that choices between two options should reflect three parameters: (1) the need of the organism, (2) the mean expected outcome of each option; and (3) the variance associated with each option's outcome. It is hypothesized that unknown probabilities are avoided because they co-occur with high outcome variability. In Experiment 3 it was found that subjects systematically avoid options with high outcome variability regardless of whether probabilities are explicitly stated or not. In Experiment 4, we reversed the ambiguity effect: when participants' need was greater than the known option's expected mean outcome, subjects preferred the ambiguous (high variance) option. From these experiments we conclude that people do not generally avoid ambiguous options. Instead, they take into account expected outcome, outcome variability, and their need in order to arrive at a decision that is most likely to satisfy this need.

Anxious adults vs. cool children: children's views on smoking and addiction.

Tobacco addiction represents a major public health problem, and most addicted smokers take up the habit during adolescence. We need to know why. With the aim of gaining a better understanding of the meanings smoking and tobacco addiction hold for young people, 85 focused interviews were conducted with adolescent children from economically deprived areas of Northern Ireland. Through adopting a qualitative approach within the community rather than the school context, the adolescent children were given the opportunity to freely express their views in confidence. Children seem to differentiate conceptually between child smoking and adult smoking. Whereas adults smoke to cope with life and are thus perceived by children as lacking control over their consumption, child smoking is motivated by attempts to achieve the status of cool and hard, and to gain group membership. Adults have personal reasons for smoking, while child smoking is profoundly social. Adults are perceived as dependent on nicotine, and addiction is at the core of the children's understanding of adult smoking. Child smoking, on the other hand, is seen as oriented around social relations so that addiction is less relevant. These ideas leave young people vulnerable to nicotine addiction. It is clearly important that health promotion efforts seek to understand and take into account the actions of children within the context of their own world-view to secure their health.

The effect of self-discrepancy and discrepancy salience on alcohol consumption.

The effect of self-discrepancy magnitude and salience on alcohol consumption was examined in an ad lib drinking study in order to evaluate the utility of the self-inflation component of the myopia model for better understanding drinking practices. Participants were 33 males and 27 females recruited on a university campus. It was predicted that participants with relatively large real self/ideal self discrepancies on dimensions important to their self-concept would consume the greatest amount of alcohol in a wine tasting test. Moreover, this effect was expected to be enhanced when self-discrepancies were made salient. The results of hierarchical regression analyses showed a main effect of gender and a significant interaction between self-discrepancy magnitude and salience condition. However, the interaction was such that wine consumption tended to decrease as discrepancy magnitude increased in the condition in which self-discrepancies were made salient, with the opposite relationship in the control condition. Three possible reasons for the unexpected findings are discussed: (a) The salience manipulation did not perform as expected: (b) the sample had little to gain from self-inflation: and (c) typically, self-inflation does not significantly motivate alcohol consumption.

Motivational interviewing in health settings: a review.

There is evidence that patient-centred approaches to health care consultations may have better outcomes than traditional advice giving, especially when lifestyle change is involved. Motivational interviewing (MI) is a patient-centred approach that is gathering increased interest in health settings. It provides a way of working with patients who may not seem ready to make the behaviour changes that are considered necessary by the health practitioner. The current paper provides an overview of MI, with particular reference to its application to health problems.

Cognitive restructuring and the 12-step program of alcoholics anonymous.

Alcohol addiction affects many clients that enter the offices of traditional mental health professionals. Their recovery is impacted by what goes on inside the office, in treatment, as well as by involvement outside the office, in 12-step programs as Alcoholics Anonymous (AA). This article examines alcoholism as a thought disorder and cognitive restructuring as an effective model of treatment. Cognitive restructuring occurs in therapy and in AA. It can, therefore, be the bridge that encourages understanding and cooperation between the two factors influencing recovery.

An event-related potential study in schizophrenia using Japanese sentences.

To examine the neurophysiological and cognitive characteristics of language disorder in schizophrenia, the N400 component and late positive component (LPC) of event-related potentials (ERPs) were investigated in medicated schizophrenic patients and health comparison subjects. The subjects were required to indicate whether Japanese sentence completions were semantically congruous or incongruous. The ERPs for the range of 300-500 ms to the incongruous completions contained a more negative component (N400), followed by LPC, which was inversely more positive for the incongruous than congruous condition. The N400 effect and the mean amplitude of the LPC were reduced in the patients. The attenuated N400 effect in schizophrenics mainly originated from an enhanced negativity for the congruous completions, suggesting that the use of context is poor in schizophrenia.

Life events, difficulties and dilemmas in the onset of chronic fatigue syndrome: a case-control study.

BACKGROUND: The role of stress in the onset of chronic fatigue syndrome is unclear. Our objectives in this study were first, to determine the relation between the onset of chronic fatigue syndrome and stressful life events and difficulties. Secondly, we examined the role of a particular type of problem, dilemmas, in the onset of chronic fatigue syndrome. METHOD: We used a case-control design with 64 consecutive referrals from an Infectious Diseases/ Liaison Psychiatry Fatigue clinic and 64 age- and sex-matched controls from a general practice population control group in Leeds. We had two main outcome measures; the odds ratios of the risk of developing chronic fatigue syndrome after experiencing a severe life event, severe difficulties or both in the year and 3 months preceding onset; and the proportion of subjects in each group who experienced a dilemma prior to onset. RESULTS: Patients with chronic fatigue syndrome were more likely to experience severe events and difficulties in the 3 months (OR = 9, 95% CI 3.2 to 25.1) and year (OR = 4.3, 95% CI 1.8 to 10.2) prior to onset of their illness than population controls. In the 3 months prior to onset 19 of the 64 patients (30%) experienced a dilemma compared to none of the controls. CONCLUSIONS: Chronic fatigue syndrome is associated with stressful events and difficulties prior to onset. Those events and difficulties characterized as being dilemmas seem to be particularly important.

Personal theories of inheritance, coping strategies, risk perception and engagement in hereditary non-polyposis colon cancer families offered genetic testing.

From the geneticist's (or 'genetic counsellor's') perspective, lay models of inheritance can be perceived as problematic because they might interfere with understanding and acceptance of the explanation of inheritance provided in genetic counselling. The work presented here forms part of a larger qualitative grounded-theory study where the aim was to develop theory that could explain variations in adjustment to genetic testing for hereditary non-polyposis colon cancer (HNPCC). Ten of the 29 individuals interviewed who were at 50% or 25% risk used a 'personal theory of inheritance' to justify or explain a belief that they did, or did not, carry the family mutation. Two others indicated that, as a coping strategy, they chose to believe themselves to be carriers. This article presents part of the theory of engagement that was constructed using this data, relating to the process of development of risk perception. The theory suggests that for some individuals, these beliefs can form part of a process of coping and coming to terms with risk. An exploration of these processes may help practitioners to better understand the complexity of risk perception in individuals at genetic risk for cancer, particularly those preparing for predictive test results. Further development and testing of the theory is discussed.

Effects of self-esteem and expected duration of interaction on liking for a highly rewarding partner.

Psychological theories predicated on the assumption of human selfishness and theories based on principles of equity may lead to conflicting predictions about when a person will like his partner. Of special interest are a person's reactions to receiving uncommonly high rewards. The present study addressed this issue by examing the development of same-sex liking in 40 female college students. It was hypothesized that subjects with lowered self-esteem, having a great need for interpersonal rewards, would react favorably to the receipt of such rewards, even if underserved. Subjects with raised self-esteem, on the other hand, having had their need for rewards met, should respond unfavorably to the receipt of high rewards, desiring a more equitable distribution of reward. These effects should be strong only when continuing dyadic interaction is expected (i.e., as issues of stability and reciprocity become salient). The predictions were confirmed.

The temporal pattern to the experience of regret.

Through telephone surveys, written questionnaires, and face-to-face interviews, it was found that people's biggest regrets tend to involve things they have failed to do in their lives. This conflicts with research on counterfactual thinking that indicates that people regret unfortunate outcomes that stem from actions taken more than identical outcomes that result from actions foregone. These divergent findings were reconciled by demonstrating that people's regrets follow a systematic time course: Actions cause more pain in the short-term, but inactions are regretted more in the long run. Support for this contention was obtained in 2 scenario experiments that assessed people's beliefs about the short- and long-term regrets of others and in an experiments that asked Ss about their own regrets of action and inaction from 2 time periods. Several mechanisms that can account for this temporal pattern are discussed.

Interactive effects of personality and mood on emotion-congruent memory and judgment.

Prior research on emotion congruency has tended to focus on either the effects of mood states or of personality traits on cognition. The aim of the present research was to explore when and how personality traits and mood states interact to influence emotion-congruent memory and judgment. In Study 1, participants filled out measures of personality and natural mood and then completed a series of memory and judgment tasks. The same procedure was used in Study 2, except a positive or negative mood state was induced prior to completion of the cognitive tasks. Extraversion and positive affectivity were related to retrieval of positive memories and the tendency to make positive judgments. Neuroticism and negative affectivity were related to retrieval of negative memories and the tendency to make negative judgments. In addition, several significant personality by mood interaction effects on memory and judgment were obtained in Study 2, which suggests that personality and mood effects on cognition are not independent of one another. Discussion focuses on integrating mood-congruency theories with personality theories and specifying the conditions under which mood by trait interaction effects effects emerge.
