Human psychobiology in Scandinavia: II. Psychoneuroendocrinology—human stress and coping processes

This paper reviews psychoneuroendocrine research on stress and coping in Scandinavia during the last two decades. Two laboratories in Stockholm, led by Marianne Frankenhaeuser and Lennart Levi, respectively, have played a particularly important role for the development of this research area, where interest is concentrated on two neuroendocrine systems, the sympathetic-adrenal medullary and the pituitary-adrenal cortical systems. Stress research in Scandinavia first followed the pioneering work by Cannon and focussed on the adrenal medullary system and the secretion of the two catecholamines adrenaline and noradrenaline. The adrenal cortical system and the secretion of the corticosteroids (cortisol), which is the basis of Selye's formulations on stress and the “general adaptation syndrom”, has been studied too, during the last 10 years. During the 1960's, pharmacological experiments were performed in order to explore the relation between psychological and physiological arousal. Psychophysiological arousal was related to performance efficiency, subjective well-being, and social adjustment. In the beginning of the 1970's systematic relationships were demonstrated between psychosocial stimulation and neuroendocrine activity. Later, the modifying influence of cognitive factors on these relationships was examined in experimental studies performed in the laboratory as well as in natural settings. The results were fitted into theoretical models, describing the possible mechanisms involved in the relationship between psychosocial stress, psychoneuroendocrine response patterns and mental and physical health. During the last decade, parallel research has been carried out in the laboratory and in real life situations. A specific Scandinavian contribution has been the combination of social psychological and psychobiological strategies in the examination of stress at the work place. Another major line of research has been the study of sex differences in psychobiological stress responses.     

Women as generalized other and self theory: A strategy for empirical research

Following the argument that women as generalized other (Mead, 1934) could be empirically explored in much the same manner as self concepts, a variant of Kuhn's (1960) twenty statements test was applied to an examination of perceptions of women in general and of the relationship between self concepts and conceptions of women. College men and women were asked to reply to the questions “Who are they (women)?” and “Who am I?” in 20 open-ended responses. Content analysis of the statements revealed findings both consistent and inconsistent with other sex-role research findings.     

Controllability and human stress: method, evidence and theory.

Concepts are defined and evidence reviewed on whether control reduces stress in man. Individuals seem to prefer instrumental control over an aversive event, seem to prefer to administer it to themselves, and are less aroused when waiting for a controllable event. When groups without control have equal predictability, having control is still less arousing; as potential (but unexercised) control seems to be. The evidence also suggests that controllable events may hurt less. Methodological weaknesses and empirical gaps in these data are pointed out. These data are grossly inconsistent with Relevant Feedback theory and rather inconsistent with Information-seeking theory and Safety Signal theory. A Minimax hypothesis is proposed: When individuals control aversive events, they believe relief to be caused by a stable source—their own response. This belief entails that maximum future danger will be minimized. When they have no control, they believe relief to be less stable, which entails no guarantee that maximum future danger will be minimized. The data are largely consistent with the Minimax hypothesis and wholly consistent when Minimax is supplemented by the premise that aversive events hurt less when encountered against a background of relaxation.     

Joint custody: research, theory, and policy

A majority of states have now enacted legislation addressing the issue of joint custody of children after divorce. This article examines current research on the subject, explores its implications for family theory, and attempts to draw some empirically based conclusions regarding policy. The literature would seem to support a structuralist view of the family and to undermine normative theories of the family life cycle. The author concludes that policy should not be aimed at developing a presumption of joint legal custody alone, but, rather, of joint physical custody with specified limitations.     

The psychobiology of trait shame in young women: extending the social self preservation theory

OBJECTIVE: The social self preservation theory (SSPT) proposes that social evaluative threat evokes the emotion of shame, which then shapes a coordinated psychobiological response. While this is supported in acute stress studies, there is no data on chronic experiences of shame. DESIGN: We investigated the association of trait shame with activity of the hypothalamic-pituitary-adrenal (HPA) axis, of the sympathetic nervous system (SNS), and regulation of inflammation in n = 56 young women. MAIN OUTCOME MEASURES: Daily profiles of salivary cortisol and alpha-amylase were assessed as indices of HPA axis and SNS activity, respectively. Inflammatory regulation was assessed by lipopolysaccharide-stimulated production and glucocorticoid inhibition of interleukin-6 in vitro. RESULTS: Trait shame was associated with SNS (r = .49; p = .001), but not HPA activity (r = .14; ns). Shame was associated with inflammatory activity (r = .35; p = .006) and glucocorticoid sensitivity (r = -0.43; p = .001). Relationships were not mediated by HPA and SNS activity. CONCLUSIONS: Results support SSPT predictions with respect to chronic shame experience and inflammation. Results further suggest the importance of SNS activation related to shame, and the possibility that HPA activation may be limited acute experiences of shame.     

Five-year retrospective on stuttering theory, research, and therapy: 1982–1987

From time to time it is worthwhile looking back and reviewing significant developments in theorizing about, researching, and treating stuttering. Retrospectives of this type have been published in the Journal of Fluency Disorders for the periods 1972–1977, and 1977–1982. The present article is the third in this series of reviews and encompasses the period 1982–1987.     

The concept of identity: research and theory.

The concept of identity is one of the few themes of psychosocial theory that has been researched directly. The dichotomy between identity achievement and role diffusion can be more accurately understood as two potential statuses among a number of resolutions to the identity crisis. Identity status appears to be related to significant childrearing experiences, particularly to dimensions of warmth, limit setting, values of autonomy, and achievement orientation. The pattern of identity achievement is different for males and females. Successful achievement of identity reflects different parental child-rearing practices for males and females.     

Hardiness: a review of theory and research.

Although a large body of research on hardiness (a personality construct with dimensions of commitment, control, and challenge) has accumulated, several fundamental issues remain unresolved. Although there are several hardiness scales, the properties of these scales have not been compared. There is debate as to whether hardiness is one or several characteristics. Research studying the pathways through which hardiness exerts its effects has not been comprehensively evaluated. Whereas critics have argued that hardiness does not buffer stress, others have suggested that hardiness buffers for working adults, for males, and in prospective analyses. There is also growing concern that hardiness is related to neuroticism. A review of the literature supports the following conclusions: The Dispositional Resilience Scale (DRS) has several advantages over alternative scales; DRS items form three factors that are consistent with hardiness theory; hardiness dimensions generally show low to moderate intercorrelations; the most common way of categorizing subjects as high or low in hardiness is not consistent with hardiness theory; hardiness does not buffer stress, and it does not buffer stress for working adults, for males, or in prospective analyses; both old and new hardiness scales inadvertently measure neuroticism. Recommendations for future research are provided.     

Empowerment theory,research, and application

This introduction to the special issue briefly reviews the meaning and significance of the empowerment concept and problems associated with the proliferation of interest in empowerment. We identify some of the topics not included in this issue and relate those to the many broad and diverse areas of psychological empowerment theory and community-based research and intervention that are covered. We present synopses of each article along with some of the themes and lessons cutting across the frameworks, studies, and applications. These include a wide diversity of settings, fairly representative of empowerment interventions, and, at the same time, improved clarity (if not unanimity) of definitions and measurement, which has been a problem in much empowerment research and intervention.     

Generalizing empirical adequacy I: multiplicity and approximation

I provide an explicit formulation of empirical adequacy, the central concept of constructive empiricism, and point out a number of problems. Based on one of the inspirations for empirical adequacy, I generalize the notion of a theory to avoid implausible presumptions about the relation of theoretical concepts and observations, and generalize empirical adequacy with the help of approximation sets to allow for lack of knowledge, approximations, and successive gain of knowledge and precision. As a test case, I provide an application of these generalizations to a simple interference phenomenon.     

Social interdependence: interrelationships among theory, research, and practice

Social interdependence theory is a classic example of the interaction among theory, research, and practice. The premise of the theory is that the way in which goals are structured determines how individuals interact, which in turn creates outcomes. Over 750 research studies have been conducted in the past 11 decades on the relative merits of cooperative, competitive, and individualistic efforts and the conditions under which each is appropriate. These studies have validated, modified, refined, and extended the theory. Social interdependence theory has been widely applied, especially in education. The applications have resulted in revisions of the theory and the generation of considerable new research.     

Schizoid phenomena,psychobiology, and psychiatric paradigms: A proposed integrative model

The history and theoretical basis of schizoid phenomena, as described by the British Object-Relations theorists, are explored as a necessary philosophic paradigm to augment the biomedical model currently dominant in Western psychiatry. A modular model of the mind that includes the notion of multiple selves, is presented. A shift in paradigms from the nineteenth century, mechanistic concept of ego, to the quantum model of the self, is seen as being more in line with contemporary science. Examples are provided from metapsychology, neurobiological brain studies, quantum mechanics and contemporary philosophy. Two clinical vignettes are presented as an illustration of the need for a philosophical framework in which to understand psychological phenomena.     

Intersubjectivity,object relations theory,and empirical evidence from mother-infant interactions

The work of John Bowlby and his associates on the development of the infant's attachment to his or her parents in the second half of the first year reflects the fruitfulness of an integration of psychoanalytic insights and empirical research. In line with this approach, this paper considers the mother-infant relationship in the first few months from two perspectives: that of the British School of Object Relations and that of the theory of Intersubjectivity, set out initially within developmental psychology and, more recently, developed within systems theory. These views are considered in the light of evidence from two sources. First, a series of experimental studies is described employing disruptions to both the form and the timing of communication between 6- to 12-week-old infants and their mothers. This work illustrates the sensitivity of young infants to the quality of their interpersonal engagements and, also, the contribution of the infant to the regulation of interactions with others. Second, evidence is presented from a prospective study of the effects of maternal depression in the postnatal period on infant development. This work shows the possible longer term consequences for the infant of early disturbances in the mother-infant relationship. Infants of postnatally depressed women were found to be more insecurely attached to their mothers, were more likely to have mild behavioral problems (especially sleep disturbance), and showed poorer outcome on Object Concept tasks at 18 months. These effects occurred despite the fact that the mother had recovered from depression by 3 months postpartum.
