Anxiety management and applied relaxation in reducing general anxiety

Sixty-three generally anxious subjects were assigned to anxiety management training, applied relaxation training, relaxation-only, placebo and untreated control conditions. After 6 weeks of treatment, anxiety management training led to reductions on a variety of self-report measures of state and trait anxiety and decreases in maladaptive cognitions during a laboratory stress procedure. On several measures, subjects in anxiety management training differed from relaxation-only and placebo subjects as well as untreated controls. However, treatment effects did not extend to performance and physiological measures of anxiety. Applied relaxation training, which in contrast to anxiety management training lacks structured rehearsal involving the recognition and reduction of tension cues during the treatment sessions, resulted in less consistent decreases in measures of general anxiety.     

Upgrading the science and technology of assessment and diagnosis: laboratory and clinic-based assessment of children with ADHD

Reviews the usefulness of clinic-based and laboratory-based instruments and paradigms for diagnosing attention deficit hyperactivity disorder (ADHD) and monitoring treatment effects. Extant literature examining the performance of normal children and those with ADHD on an extensive range of neurocognitive tests, tasks, and experimental paradigms indicates that particular types of instruments may be more reliable than others with respect to detecting between-group differences. We review task parameters that may distinguish the more reliable from less reliable instruments. The value of clinic-based and laboratory-based instruments for monitoring treatment response in children with ADHD is questionable when evaluated in the context of ecologically relevant variables such as classroom behavior and academic functioning. We present a general conceptual model to highlight conceptual issues relevant to designing clinic-based and laboratory-based instruments for the purposes of diagnosing and monitoring treatment effects in children with ADHD. Application of the model to currently conceptualized core variables indicates that attention and impulsivity-hyperactivity may represent correlative rather than core features of the disorder. We discuss implications of these findings for designing the next generation of clinic-based and laboratory-based instruments.     

Possible Environmental Causes of Stages in Moral Reasoning

Both children (6-, 10-, and 14-year-olds) and their mothers were interviewed. The children's responses to moral dilemmas were classified into Kohlberg's three main categories—preconventional, conventional, and postconventional. The mothers were presented with a variety of hypothetical situations—e.g., they had just found out that their child had stolen something, and were asked to tell what they would say or do to their child in each situation. The mothers' hypothetical responses to such situations were divided into either the preconventional, conventional, or postconventional category depending on the level or moral reasoning such responses would imply to their children. The results indicated that as the age of the children increased, both the level of moral reasoning used by the children and the level of moral reasoning implied by the mothers' treatment of the children increased. Even with age partialed out, there was a significant positive relationship between the mothers' implied level of moral reasoning and the children's level of moral reasoning. Thus, although causality cannot be established, the results indicate that there is at least the possibility that environmental changes—i.e., changes in the way the mother treats the child—may be responsible for the appearance of stages in the child's development of moral reasoning.     

Stress responsivity among dysmenorrheic women at different phases of their menstrual cycle: more ado about nothing

Dysmenorrheic and nondysmenorrheic women in the follicular, luteal and menstrual phase of their menstrual cycle participated in a stressful laboratory procedure. Pulse rate, pulse volume and skin conductance were measured continuously during baseline, during confrontation of three stressful tasks (i.e. stress-reactivity periods) and following each confrontation (i.e. stress-recovery periods). The hypothesis that dysmenorrheic Ss in the menstrual phase of their cycle would show greater stress responsitivity was generally not confirmed, and the broader contention that women differ in their stress responsivity as a function of their menstrual cycle phase was shown to be of questionable validity.     

The path of visual attention

Visual cuing is one paradigm often used to study object- and space-based visual selective attention. A primary finding is that shifts of attention within an object can be accomplished faster than equidistant shifts between objects. The present study used a visual cuing paradigm to examine how an object's size (i.e., internal distance) and shape, influences object- and space-based visual selective attention. The first two experiments manipulated object size and compared attentional shift performance with objects where the within-object distance between cued and uncued target locations was either equal to the between-object distance (1:1 ratio condition) or three times the between-object distance (3:1 ratio condition). Within-object shifts took longer for the larger objects, but an advantage over between-object shifts was still evident. Influences associated with the shapes of the larger objects suggested by the results of the first two experiments were tested and rejected in Experiment 3. Overall, the results indicate that within-object shifts of attention become slower as the within-object distance increases, but nevertheless are still accomplished faster than between-object shifts.     

Yes we can!: prejudice reduction through seeing (inequality) and believing (in social change)

We investigated the effect of differential perceived efficacy to reduce racial inequality (in the context of increased awareness of illegitimate in-group advantages) on White Americans' intergroup attitudes and antidiscrimination behavior. White American university students read a passage describing the underrepresentation of African Americans in their university's faculty and then wrote letters to the university administration in support of appointing more African Americans to the faculty. We experimentally varied feedback concerning efficacy to change institutional racism. Before writing their letters, participants were told that there was a low, moderate, or high chance that their efforts would be effective. Later in the experiment, participants' perceived efficacy to influence their university system was measured. Intergroup attitudes improved and antidiscrimination actions increased among participants with higher perceived efficacy in comparison with participants with low perceived efficacy. Collective guilt partially mediated the effects of efficacy beliefs on antidiscrimination actions and fully mediated the effects of efficacy beliefs on intergroup attitudes.     

Internalizing behavior problems and scholastic achievement in children: cognitive and behavioral pathways as mediators of outcome.

Examined a conceptual model in which dual developmental pathways (behavioral and cognitive) are hypothesized to account for the relation among internalizing behavior problems, intelligence, and later scholastic achievement using a cross-sectional sample of 325 children. Classroom behavior and select aspects of cognitive functioning (vigilance, short-term memory) were hypothesized to mediate the relations among internalizing problems, IQ, and long-term scholastic achievement. Hierarchical tests applied to a nested series of models demonstrated that (a) individual differences in measured intelligence among children are associated with variations in classroom performance and cognitive functioning, (b) classroom performance and cognitive functioning make unique contributions to prediction of later achievement over and above the influence of intelligence, (c) anxious/depressive features are correlated but separable constructs, and (d) anxiety/depression and withdrawal contribute to prediction of classroom performance and cognitive functioning over and above the effects of intelligence. Classroom performance and cognitive functioning thus appear to mediate the effects of internalizing behaviors as well as intelligence. Particular attention to the presence and potential impact of social withdrawal on children's functioning, both alone and concomitant with anxiety/depression, appears warranted during the course of clinical evaluations owing to the strong continuity among these variables.     

Posttraumatic spiritual growth: a phenomenological study of cancer survivors

A small but growing body of research has sought to investigate the specific role of religion and spirituality in posttraumatic growth. Recently, investigations have reported identifying spiritual growth following trauma, specifically that of cancer patients and survivors. The purpose of this qualitative study was to investigate how having cancer affects the spiritual growth of cancer survivors across a multidimensional conceptualisation of spirituality. The researchers investigated posttraumatic spiritual growth by studying the lived experience of 13 cancer survivors using phenomenological data analysis. Participants reported experiencing spiritual growth across the following domains of spirituality: (a) general spirituality, (b) spiritual development, (c) spiritual social participation, (d) spiritual private practices, (e) spiritual support, (f) spiritual coping, (g) spirituality as motivating forces, (h) spiritual experiences, and (i) spiritual commitment. Growth was not endorsed by participants in the following three domains of spirituality outlined in the model: (a) spiritual history, (b) spiritual beliefs and values, and (c) spiritual techniques for regulating and reconciling relationships. Two additional domains of growth emerged beyond the theoretical model that was used to guide this study from participants’ narratives, including evangelism and enhanced spirituality of family/friends.     

Stimulant effects in attention deficit hyperactivity disorder: theoretical and empirical issues

The explanatory utility of a theory or model of ADHD or any disorder depends fundamentally on its capacity to address issues of causality. What causes a particular child to develop ADHD? What mechanisms are responsible for temporal and setting-related variations in symptom severity, and how are these mechanisms affected by pharmacological intervention? And, what processes determine whether gains in one domain will propagate across one or more others? It should be evident from the foregoing discussion that comprehensive answers to such questions are most likely to emerge through implementation of research strategies that (a) integrate biological and psychological levels of explanation, (b) permit analysis of causal hypotheses, and (c) address mechanisms involved in both etiology and mediation of treatment response. Although extant neurobiological studies of ADHD are as compelling as they are exciting, they are limited by a troubling reductionistic emphasis. The predominant animal models focus on a narrow range of behaviors that are presumed to be central to ADHD because of the topographic similarity they bear to those represented by the diagnostic criteria incorporated into the diagnostic nomenclature. These models would become increasingly valuable to the extent that future research examined the extent to which ecologically relevant behaviors (e.g., social behavior) are compromised in the animal strains and whether the observed compromises are parallel to the correlates of ADHD observed in humans. Similarly, human molecular genetic studies have provided a glimpse into the possible role that genes related to dopaminergic neurotransmission may play in the etiology of ADHD. Yet, the features of ADHD have been conceptualized in these investigations as a unitary collection of characteristics, and this has precluded analysis of what specific syndromal feature (if any single one) is affected by the implicated genes. It is intriguing to speculate whether varying combinations of genes governing properties of DA receptors and reuptake molecules are associated with different patterns of symptom severity or responses to stimulant medications. As testing procedures for determining genotypes with respect to these features become more affordable and available, it should become increasingly feasible to examine such issues empirically. Research on the utility of stimulant drugs as a treatment for ADHD also has yielded useful information. Although the effects of MPH are of short duration, the breadth of their impact is impressive. The clinical effectiveness of these medications is no longer in doubt, and patterns of relations among outcome measures represent a potentially fruitful target of scientific inquiry. Finally, data supporting a neurobiological substrate for ADHD, evidence indicating that task and setting variables moderate the expression of the syndrome's diagnostic features (see Barkley, 1998, for a review), and the causal emphasis of the conceptual model with which the discussion began collectively argue for a diathesis-stress conception of the syndrome. And, as foregoing comments make clear, task and setting variables and the mechanisms through which they influence symptom expression are as important to the phenomenon as are neurobiological predisposing causes. This has significant implications for assessment strategies employed in diagnosis and evaluation of treatment-outcome. Specifically, it suggests that theory-based experimental manipulations of task and setting variables designed to impose challenge on hypothesized core features of the disorder are more likely to yield insights into the causal mechanisms governing behavioral organization in affected children than strategies emphasizing static identification of diagnostic correlates. It is hoped that such an approach will accelerate the discovery of increasingly effective assessment and intervention strategies.
