Clinical utility of the MMPI in the evaluation of adolescent suicide attempters

MMPI profiles of female adolescents hospitalized on a general pediatrics floor following a suicide attempt were compared to a control group of medically hospitalized, female adolescents referred for psychiatric evaluation. The suicide attempters had only a lower score on the K scale when compared to the control group. Results do not suggest that a single MMPI profile differentiates suicide attempters from a comparison group of adolescents with emotional difficulties. Implications of these findings are discussed.     

Aggregate item response analysis

A stochastic postulate is given for the multiple-item, successive-intervals scaling of populations. The logistic equivalent of this postulate provides an aggregate item response model in which a unidimensional submodel may be nested. This reduction provides a subtractive conjoint measurement of several items and stimuli on the same latent scale. Generalized-least-squares methods are used to estimate and test the multiple-item model, and its unidimensional reduction, on aggregate survey responses. The entire procedure is illustrated with an analysis of semantic-differential attitude data. This analysis exhibits an item selection procedure that is applicable to various social constructs.The authors dedicate this paper to the memory and contributions of Clyde Coombs.The programming and data analyses for the present paper were carried out by José Ventura of the Department of Industrial and Systems Engineering, and Jerry Meiten of the Department of Statistics, University of Florida.The study was also supported by the College of Business Administration, University of Florida, and the Faculty of Social Sciences, Hebrew University of Jerusalem.     

Reinforcer pathology,probabilistic choice,and medication adherence in patients with multiple sclerosis

The reinforcer pathology model posits that core behavioral economic mechanisms, including delay discounting and behavioral economic demand, underlie adverse health decisions and related clinical disorders. Extensions beyond substance use disorder and obesity, however, are limited. Using a reinforcer pathology framework, this study evaluates medical adherence decisions in patients with multiple sclerosis. Participants completed behavioral economic measures, including delay discounting, probability discounting, and a medication purchase task. A medical decision-making task was also used to evaluate how sensitivity to mild side effect risk and efficacy contributed to the likelihood of taking a hypothetical disease-modifying therapy. Less steep delay discounting and more intense (greater) medication demand were independently associated with greater adherence to the medication decision-making procedure. More generally, the pattern of interrelations between the medication-specific and general behavioral economic metrics was consistent with and contributes to the reinforcer pathology model. Additional research is warranted to expand these models to different populations and health behaviors, including those of a positive health orientation (i.e., medication adherence).     

The nature space. A reflexive thematic analysis of therapists' experiences of 1:1 nature-based counselling and psychotherapy with children and young people: Exploring perspectives on the influence of nature within the therapeutic process

Nature-based therapy is an emerging and rapidly developing field within counselling and psychotherapy, yet there is little published empirical research, or integrated models relating to its practice with Children and Young People (CYP). The present study aimed to explore therapists’ experiences of one-to-one nature-based counselling and psychotherapy with CYP, eliciting perspectives on the interaction between nature and the therapeutic process. A reflexive thematic analysis provides preliminary insights into possible mechanisms of action with the potential to inform a longer-term exploration of whether nature-based therapy is effective, for whom and why. The study highlights the need to better explore and understand how nature-based therapy supports relational and intrapsychic change in interaction with developmental processes, to inform construction of coherent and consolidated theory and models for practice.     

Classical and bayesian inference in certain latency processes

Certain aspects of point estimation are treated for two kinds of exponential latency processes. The first unitary process is represented by a simple exponential density in which the rate parameter may be viewed as an unknown constant or as a random variable. If a second, slower exponential process is grafted onto the first, there results a postulated two-component latency between stimulus and response. Moments estimators are derived for the two parameters of this latter density, and the relevance of the second parameter to decision time is emphasized.This research was supported in part by National Institutes of Health Grant MH-04439-05.

The transference neurosis in Freud's writings

This paper reviews the evolution of the concept of transference neurosis in Freud's writings. It suggests that the language in which the concept of the transference neurosis is originally expressed by Freud includes an idea of the analyst as aggressively pursuing the analytic cure by waging a solitary battle against the patient's disease. With the representation of the death drive and the larger role accorded to sadism as its external manifestation in Freud's revised drive theory of 1920, the patient becomes the ally; resistance, in the sense of the conservative forces, not disease, in the sense of libidinal conflict, becomes the enemy. It is thus difficult to speak of a transference neurosis in the circumscribed way Freud originally meant it, and he ceased to use the term after 1926 rather than redefine it to fit his broader perspective. In this broader perspective, relative resolution of conflict replaced radical liberation of the patient from disease. That Freud did not redefine the term does not imply that he discarded it, or that we necessarily should. This paper suggests that Freud implied a functional distinction between transference as transforming agent and transference neurosis as result of that transformation. That distinction defines psychoanalytic cure in terms of the understanding of a symbolic transformation which is, through the transference neurosis, reexperienced as part of the psychoanalytic process.
