Response to commentary on the multimodal treatment study of ADHD (MTA): mining the meaning of the MTA

In the December 2000 issue of the Journal of Abnormal Child Psychology, we published a set of papers presenting secondary analyses of the Multimodal Treatment Study of ADHD (MTA), and R. A. Barkley (2000) provided a commentary. A critique of the design of the study (MTA Cooperative Group, 1999) was presented based on a theoretical perspective of a behavioral inhibition deficit that has been hypothesized as the core deficit of ADHD (R. A. Barkley, 1997). The commentary questioned the design and analysis of the MTA in terms of (1) the empirical criteria for selection of components of behavioral (Beh) intervention, (2) the effectiveness of the Beh intervention, (3) the methods for analyses at the group and individual level, (4) implications of the MTA findings for clinical practice, (5) the role of genetics in response to treatment, and (6) the lack of a nontreatment control group. In this response, we relate the content of the papers to the commentary, (1) by reviewing the selection criteria for the Beh treatment, as outlined by K. C. Wells, W. E. Pelham, et al. (2000), (2) by addressing the myth that the MTA Beh treatment was ineffective (Pelham, 1999), (3) by describing the use of analyses at the level of the individual participant, as presented by J. S. March et al. (2000) and W. E. Pelham et al. (2000) as well as elsewhere by J. M. Swanson et al. (2001) and C. K. Conners et al. (2001), (4) by relating some of the suggestions from the secondary analyses about clinically relevant factors such as comorbidity (as presented by J. S. March et al., 2000) and family and parental characteristics (as presented by B. Hoza et al., 2000, S. P. Hinshaw et al., 2000, and K. C. Wells, J. N. Epstein, et al., 2000), (5) by discussing the statistical concept of heritability and the lack of a significant difference in the presence of ADHD symptoms in parents of the MTA families compared to parents in the classmate-control families (as presented by J. N. Epstein, et al., 2000), and (6) by acknowledging that an ethically necessary weakness of the MTA design is that it did not include a no-treatment control group. We discuss the use of secondary analyses to suggest how, when, and for what subgroups effectiveness of the Beh treatment may have been manifested. Finally, we invite others to use the large and rich data set that will soon be available in the public domain, to perform secondary analyses to mine the meaning of the MTA and to evaluate theories of ADHD and response to treatments.     

Therapists facing masks: A qualitative study of the nature of relationships between masks and relational depth

Background

Central to this research was exploring characteristics facilitating and disinhibiting meetings at relational depth to explore underlying driving factors of change. The overall aim was to explore relationships between masks and relational depth. Viewing masks as a characteristic sought to understand further the socio-cultural impacts of masks on client/patient care and decision-making to meet at depth. This research demonstrates immediate social and international context due to COVID-19.

Methods

A phenomenological methodology was utilised. The primary research vehicle was an examination of primary data from semi-structured interviews. Four therapists who had used masks within sessions (where both therapist and clients wore masks) provided data on meetings at relational depth.

Findings

Interpretative phenomenological analysis revealed four themes: ‘epicentre of aetiology’, ‘loss’, ‘masked-disinhibition’ and ‘disconnection paradox: depth through disconnection’. Findings suggest masks are a characteristic that can facilitate and inhibit meetings at depth—acknowledging common factors, including how therapists related to masks as an extended part of the client, and mutuality within disconnection to masks, not one another, was significant.

Conclusions

Findings suggest the exigent presence of masks could facilitate or inhibit meetings at depth, regulated by what masks represented to therapists/clients at moments of contact. Yet, when both therapist and client appeared mutually disconnected (to masks, not each other), they found moments of relational depth within the disconnection. Masks are suggested as a characteristic that can influence meetings at depth. Opportunities for depth seemed reliant on individual capabilities to offer depth, emphasising therapists' experiential awareness of their interoceptive process.     

The effect of state core self-evaluations on task performance,organizational citizenship behaviour,and counterproductive work behaviour

Although the personality–performance relationship has been studied extensively, most studies focused on the relationship between between-person differences in the Big Five personality dimensions and between-person differences in job performance. The current paper extends this research in two ways. First, we build on core self-evaluations (CSEs): an alternative, broad personality dimension that has proven to be a good predictor of job performance. Second, we tested concurrent and lagged within-person relationships between CSEs and task performance, organizational citizenship behaviour (OCB), and counterproductive work behaviour (CWB). To this end, we conducted two experience sampling studies; the first one assessing the relationship between state CSEs and levels of momentary task performance and OCB, and a second study in which employees reported on their level of state CSEs and momentary CWB. Results showed that there is substantial within-person variability in CSEs and that these within-person fluctuations relate to within-person variation in task performance, OCB, and CWB towards the organization, and CWB towards the individual. Moreover, CSEs prospectively predicted within-person differences in task performance and CWB towards the organization, whereas the reversed effect did not hold. These findings tentatively suggest that state CSEs predict performance, rather than the other way around.     

A Richer or a Poorer Naturalism?

Willem Drees endorses not only minimal naturalism, understood as the rejection of supernatural interruptions of the world's normal causal processes, but also maximal naturalism, with its reductionistic materialism. Besides arguing that this reductionistic naturalism provides the best framework for interpreting science, he believes that it is compatible with religion (albeit of a minimalist sort). The "richer" naturalism advocated by Whiteheadians is, accordingly, unnecessary. Drees's position, however, cannot do justice to a number of "hard-core commonsense notions," which we inevitably presuppose in practice and thereby in science as well as religion. His naturalism is too poor, in particular, to account for subjectivity, freedom, and mathematical, religious, and moral experience.     

The analysis of multitrait-multimethod matrices via constrained components analysis

Multitrait-Multimethod (MTMM) matrices are often analyzed by means of confirmatory factor analysis (CFA). However, fitting MTMM models often leads to improper solutions, or non-convergence. In an attempt to overcome these problems, various alternative CFA models have been proposed, but with none of these the problem of finding improper solutions was solved completely. In the present paper, an approach is proposed where improper solutions are ruled out altogether and convergence is guaranteed. The approach is based on constrained variants of components analysis (CA). Besides the fact that these methods do not give improper solutions, they have the advantage that they provide component scores which can later on be used to relate the components to external variables. The new methods are illustrated by means of simulated data, as well as empirical data sets.This research has been made possible by a fellowship from the Royal Netherlands Academy of Arts and Sciences to the first author. The authors are obliged to three anonymous reviewers and an associate editor for constructive suggestions on the first version of this paper.     

EVOLUTION AND SPECIAL CREATION

Abstract. The logical relationships between the ideas of evolution and of special creation are explored here in the context of a recent paper by Alvin Plantinga claiming that from the perspective of biblical religion it is more likely than not that God acted in a "special" way at certain crucial moments in the long process whereby life developed on earth. I argue against this thesis, asking first under what circumstances the Bible might be thought relevant to an issue of broadly scientific concern. I go on to outline some of the arguments supporting the thesis of common ancestry, and argue finally that from the theistic perspective, special creation ought to be regarded as, if anything, less rather than more likely than its evolutionary alternative.     

Deci and Ryan's cognitive evaluation theory of intrinsic motivation: A set of common sense theorems

Cognitive evaluation theory as put forward by Deci and Ryan (1985) is examined. The theory, which deals with intrinsic and extrinsic motivation, has inspired considerable amount of empirical research in the last two decades. However, contrary to the mainstream view and that of its authors, it is argued here that the theory consists of necessary truths of common sense (folk) psychology, rather than contingent and empirically testable hypotheses. As such the theory spells out what must necessarily be the case in human motivation and the empirical evidence amassed to test its validity is irrelevant. Such testing should be abandoned if its purpose is to appraise the truth value of the theory's propositions. To empirically test necessary true propositions is not only redundant in such cases, but also a waste of time and resources.
