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.     

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.     

Combining nonoverlap and trend for single-case research: Tau-U

A new index for analysis of single-case research data was proposed, Tau-U, which combines nonoverlap between phases with trend from within the intervention phase. In addition, it provides the option of controlling undesirable Phase A trend. The derivation of Tau-U from Kendall's Rank Correlation and the Mann-Whitney U test between groups is demonstrated. The equivalence of trend and nonoverlap is also shown, with supportive citations from field leaders. Tau-U calculations are demonstrated for simple AB and ABA designs. Tau-U is then field tested on a sample of 382 published data series. Controlling undesirable Phase A trend caused only a modest change from nonoverlap. The inclusion of Phase B trend yielded more modest results than simple nonoverlap. The Tau-U score distribution did not show the artificial ceiling shown by all other nonoverlap techniques. It performed reasonably well with autocorrelated data. Tau-U shows promise for single-case applications, but further study is desirable.     

A contact-pencil for research on writing

A pencil is described which closes a circuit when the lead is in contact with the writing surface. Its advantages over previous devices lie in simplicity, cost and reliability; it leaves a normal pencil trace on ordinary paper; and due to its novel mode of action, the movement of the writing element is extremely small, comparable with normal writing instruments.     

Attachment theory and systemic practice: research update

Attachment theory offers a way of thinking about the dyadic relationships within the family system. Family systems theory and therapy can contribute to attachment theory, as dyadic relationships do not exist in isolation but within the context of other relationships. Research at the interface between systemic practice and attachment theory is reviewed with examination of the central role they may play together in the developing understanding of family relationships.     

Combining computerized home-based treatments for generalized anxiety disorder: an attention modification program and cognitive behavioral therapy

Generalized anxiety disorder (GAD) is a common and disabling condition associated with significant personal and societal costs. Although efficacious treatments exist for GAD, the majority of these individuals fail to access our most effective treatments. In the current paper, we report the results of an open trial that examined the efficacy of a computer-delivered home-based treatment program for GAD. Twenty-one individuals seeking treatment for GAD received a self-administered program over 6 weeks that comprised two components: (1) an Attention Modification Program (AMP) designed to facilitate attentional disengagement from threat-relevant stimuli and (2) brief computer-delivered cognitive and behavioral treatment modules (CCBT). Fourteen of the 21 enrolled participants (67%) completed the treatment program. Intent-to-treat and completer analyses revealed that AMP+CCBT resulted in significant reductions in clinician- and self-rated symptoms of anxiety, worry, depression, and functional impairment. Moreover, treatment completers displayed significant reductions in attentional bias for threat from pre- to postassessment. Change in attentional bias for threat from pre- to postassessment was associated with change in worry symptoms. Finally, 79% of participants no longer met DSM-IV criteria for GAD at postassessment and 36% were classified as remitted (Hamilton Rating Scale for Anxiety ≤7; Rickels et al., 2006). These results suggest that computer-delivered AMP+CCBT may serve as an effective and easily accessible treatment option for individuals with GAD.     

From theory to application and back again: implications of research on medical expertise for psychological theory.

Research directed at an understanding of medical expertise is about 30 years old, and many developments in this literature parallel progress in cognitive psychology. Over the past 15 years or so, this research became much more closely identified with particular psychological theories. Initial forays into medicine were essentially direct applications of methods developed in the psychology lab to the more natural domain of medicine, with varying degrees of success. These attempts were followed by a second wave that took the psychological theories themselves more seriously in a more thoughtful application of psychological methods to the medical domain. I will argue in the present paper that the methods and theories used in the study of medical expertise have advanced to the point that there is some reverse flow and they are providing a unique and valuable perspective on the nature of thinking.     

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.     

Alcohol and creative writing.

A repeated-measures design was used to test for the effects of alcohol on creative writing as measured by use of novel figurative language. 11 male social drinkers participated in a creative writing task under two conditions, alcohol (high dose: 1.1 ml. ethanol/kilogram body weight) and placebo. In the alcohol condition, within-subject comparisons indicated significantly greater quantity of creative writing while intoxicated. These results were interpreted as supporting the belief that alcohol can reduce "writer's block," at least amongst nonalcoholic subjects.     

Weapons and violence: A review of theory and research

Weapons are used in approximately one quarter of all violent incidents and the majority of homicides in the US, and the UK. Despite their overwhelming contribution to violent harm, theories of weapon related behaviors are scarce, and little is known of their correlates. This paper reviews available theories of weapon related behavior and identifies a number of motivations for weapon carrying, such as self defense, victim coercion, causing harm and self presentation. Correlates of weapon carrying and weapon use such as age, gender, socioeconomic status, exposure to weapons and history of aggression are explored and a number of limitations to current research approaches are identified. The review concludes with a discussion of future directions for research.     

The generation of visual images: a review of neuropsychological research and theory.

Since the advent of the view that mental imagery is a subdividable process, claims have been made that the generation of images is the domain of the left posterior hemisphere. This article examines theory and data about the neuropsychology of image generation by focusing on the main contributors to the debate. An attempt is made to make the theory and beliefs associated with each of the key figures explicit, because these have influenced the structure of research and the development of new theories. Support is found for the involvement of the left hemisphere, although many researchers claim that the posterior regions of both hemispheres contribute to image generation but that they do so in different ways. The nature of this difference remains the subject of ongoing research.     

Emotion in career contexts: Challenges for theory and research

In this article I argue that we need a greater understanding of the role of emotion in career development and career management. Notions of careers as sequences of events and experiences and new relational approaches to organizational career development suggest opportunities for exploring the experience, expression, and management of emotion within individuals’ careers. Also, ideas about emotional labour can inform career counselling practice. I also explore how far research into emotions in career contexts requires a constructivist or constructionist approach, and discuss some of the methodological issues in working within positivist, and non-positivist (specifically constructivist and constructionist) paradigms. Both have their strengths, and we should not lose sight of these in furthering our understanding of individuals’ careers and of ways to intervene effectively in career development.     

Human psychobiology in Scandinavia: I. Psychophysiology—theory, method and empirical research

The present paper reviews Scandinavian contributions to the field of psychophysiology in a fifteen year perspective (1968–1983). Psychophysiology is defined as that domain within psychobiology where the investigator uses a physiological measure to indirectly assess a psychological construct, e.g. heart-rate to index anxiety. Only research that fit this definition is reviewed. Thus, research belonging to physiological psychology and behavior pharmacology is excluded. The paper is divided into several areas covering studies related to attention and the orienting response (OR); classical autonomic conditioning and biofeed-back learning; clinical psychology and behavior medicine; emotion and motivation, and methodological contributions. The review of studies related to attention and OR is focussed on the work by Näätänen and by Öhman who both have made distinguished contributions to this area of research. The so-called "prepared-learning" project is described as an example of Scandinavian conditioning studies. Other examples include Bohlin's research on attention and habituation, and the work by Schalling and by Fredrikson in clinical psychology and psychopathology. Norwegian research on muscle tension and respiratory activity done by Svebak is also reviewed. A total of 114 papers written by about 95 different researchers are reviewed. Thus, psychophysiology may be regarded as a firmly rooted research tradition in Scandinavia, both qualitatively and quantitatively. It is concluded that Scandinavian psychophysiology research is at the front line internationally concerning problem areas and methodology.
