The six most essential questions in psychiatric diagnosis: a pluralogue part 1: conceptual and definitional issues in psychiatric diagnosis

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM - whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article will take up the first two questions. With the first question, invited commentators express a range of opinion regarding the nature of psychiatric disorders, loosely divided into a realist position that the diagnostic categories represent real diseases that we can accurately name and know with our perceptual abilities, a middle, nominalist position that psychiatric disorders do exist in the real world but that our diagnostic categories are constructs that may or may not accurately represent the disorders out there, and finally a purely constructivist position that the diagnostic categories are simply constructs with no evidence of psychiatric disorders in the real world. The second question again offers a range of opinion as to how we should define a mental or psychiatric disorder, including the possibility that we should not try to formulate a definition. The general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.     

Integrating sport psychology and sports medicine in research: The dilemmas

Abstract

The recent acceleration of interest in conducting sport psychology research within sports medicine settings has prompted an introspection on the stringency of sport injury-focused research protocols and methodology. Much of the literature relating to the psychology of sport injury is anecdotal, comprised of conjecture, or is an extrapolation from allied psychological study. In addition, retrospective studies, involving the recall of an unpleasant event (i.e., sport injury) proliferate the literature. Quality research that integrates sport psychology and sports medicine presents a unique challenge because of the multifactorial nature of sport injury and the necessity for sound interpretation of research outcomes relative to the nature of psychology. sport, and injury. Confounding and complicating aspects of this integrated research include definition of injury variables, timing of data collection. evaluation of pain. and the physiological sequelae of injury. Research and methodological issues relating to sport psychology and sport injury are discussed.     

Charisma attribution during organizational change: the importance of followers' emotions and concern for well‐being

Taking a follower‐centric perspective, we examined how charisma attribution to a change leader was influenced by the well‐being concerns and emotions of organizational members. We conducted three studies to examine how college business students and Executive Master of Business Administration (EMBA) students responded to a grading policy reform aimed at reducing grade inflation. We found that emotions and well‐being concerns such as school year and grade point average influenced charisma attribution by the undergraduate students and that there was a greater divergence of emotional reactions and charisma attribution among undergraduate students than among the executive MBAs. Future directions for follower‐centric leadership research on charismatic leadership are discussed.     

The Effects of Spatial Frequency and Temporal Waveform on Three Measures of Temporal Processing

The effects of spatial frequency and temporal transition of sine-wave grating onset and offset were assessed using measures of reaction time, visual persistence, and temporal order judgments. The stimuli were lateralized fields, separated by 1° of visual angle. Slow temporal transition resulted in significantly poorer performance than did abrupt onset and offset, but spatial frequency had a minimal effect. Thus, the latency, temporal resolution, and temporal ordering of events are mediated by a mechanism that is sensitive to abrupt temporal transients. The stimulus conditions employed did not result in a shift in the point of subjective simultaneity.     

Infant-led innovations in a mother-baby therapy group

A mother-baby therapy group for mothers and infants in their first year who are experiencing difficulties is described. In a literature review no comparable group where the infants are seen as members in their own right has been found. Themes in the mothers' material are outlined, followed by the infants' evolving interactive and internal processes. Some therapeutic factors, in particular interactions between the infants and interventions on the part of the therapists, are then illustrated with clinical material. Some infant-led innovations are described, such as the way the infants' activity is used as a basis for making ‘group as a whole’ interpretations, and in particular how the therapists' actions towards the infants have come to be viewed as a non-verbal form of interpretation. The role of attuned play in direct work with infants is discussed further.     

A Direct Method of Assessing Underlying Cognitive Risk for Adolescent Depression

An enduring tendency towards negative thinking is thought to increase vulnerability for future depression. However, it has not been possible to assess this tendency in non-depressed mood states. We examined if response latency to endorse dysfunctional attitudes is associated with depressive outcomes in a longitudinal study. A sample of young people at familial risk of depression (N?=?252, aged 10–19, 56.3 % female) completed a computer-administered dysfunctional attitude scale. The main outcome measure was the difference in reaction time to agree versus disagree with dysfunctional attitudes. Cross-sectional differences between current and previous depression and no psychiatric disorder groups as well as longitudinal associations with depressive symptoms were examined. Young people with current and previous depression were quicker to agree with dysfunctional attitudes than those without disorder. In young people free from depressive disorder, faster agreements with dysfunctional attitudes were specifically associated with increased depressive symptoms over time. Self-reported dysfunctional attitudes did not differentiate the formerly depressed and no disorder groups and showed a longitudinal association with depressive symptoms for older adolescents only. Reaction time to endorse dysfunctional attitudes may indicate changes in affective processing that represent an early risk for future depression that is not indexed by self-report measures of negative thought.     

The representation of category typicality in the frontal cortex and its cross-linguistic variations

When asked to judge the membership of typical (e.g., car) vs. atypical (e.g., train) pictures of a category (e.g., vehicle), native English (N = 18) and native Chinese speakers (N = 18) showed distinctive patterns of brain activity despite showing similar behavioral responses. Moreover, these differences were mainly due to the amount and pervasiveness of category information linguistically embedded in the everyday names of the items in the respective languages, with important differences across languages in how pervasive category labels are embedded in item-level terms. Nonetheless, the left inferior frontal gyrus and the bilateral medial frontal gyrus are the most consistent neural correlates of category typicality that persist across languages and linguistic cues. These data together suggest that both cross- and within-language differences in the explicitness of category information have strong effects on the nature of categorization processes performed by the brain.
