Are True Scores and Construct Scores the Same? A critical examination of their substitutability and the implications for research results

Relations between constructs are estimated based on correlations between measures of constructs corrected for measurement error. This process assumes that the true scores on the measure are linearly related to construct scores, an assumption that may not hold. We examined the extent to which differences in distribution shape reduce the correlation between true scores on a measure and scores on the underlying construct they are intended to measure. We found, via a series of Monte Carlo simulations, that when the actual construct distribution is normal, nonnormal distributions of true scores caused this correlation to drop by an average of only .02 across 15 conditions. When both construct and true score distributions assumed different combinations of nonnormal distributions, the average correlation was reduced by .05 across 375 conditions. We conclude that theory‐based scales intended to measure constructs usually correlate highly with the constructs they are constructed to measure. We show that, as a result, in most cases true score correlations only modestly underestimate correlations between different constructs. However, in cases in which the two constructs are redundant, this underestimation can lead to the false conclusion that the constructs are ‘correlated but distinct constructs,’ resulting in construct proliferation.     

Lies and Body Cruelties in the Analytic Hour

Discussing an intensive case study of female sexual dysfunction, this paper studies mutual deregulation and disintegration as it unfolds in the transference–countertransference dyad. I propose that ethical transgressions are potentiated in analytic dyads in which the analyst's hope for either solitude or mutuality is foreclosed. This hope can be foreclosed by the particulars of the therapeutic interaction as well as by the theoretical and clinical aspects of analytic training. The deregulation that both precipitates and follows such transgression can be healed (in the analyst, in the analysis) only by the restitution of the therapist's agency, the reduction of paranoid-schizoid guilt and shame, and the location (in the analyst) of depressive, “I-Thou” remorse.     

Bill Clinton and John E Kennedy: The Dark Side of Charisma

In this review essay, I provide a summary of the basic tenets of Stuart A. Pizer's book, Building Bridges: The Negotiation of Paradox in Psychoanalysis. Focusing on the concepts of negotiation, paradox, and potential space, he privileges them as constituting the basic structure and process of the analytic relationship. Therapeutic action resides specifically in the analyst's optimizing of the potential space within which intrapsychic and interpersonal negotiation can occur. Negotiating paradox is a uniquely human capacity, difficult to sustain, but essential for a “distributed” self, one that is decentered and dynamic rather than disassociated. Pizer extends the reach of these concepts by developing them in relation to gender, evolution, species, and mediation. He also considers that which is nonnegotiable, a relational property between analyst and patient, at the brink of which deep analysis occurs. The book, with its elegant theoretical model and clinically useful tool, provides a rich potential space within which I was able to engage fruitfully.     

Effect of Age and Gender in the Control of Elbow Flexion Movements

In previous studies of rapid elbow movements in young healthy men, characteristic task-dependent changes in the patterns of muscle activation when movement speed or distance was varied have been reported. In the present study, the authors investigated whether age or gender is associated with changes in the patterns of muscle activity previously reported in young men. Arm movements of 10 healthy older and 10 healthy younger participants (5 men and 5 women in each group) were studied. Surface electromyograms (EMGs) from agonist (biceps) and antagonist (triceps) muscles, kinematic and kinetic parameters, as well as anthropometric and strength measures were recorded. All 4 groups of participants showed similar task- (distance or speed) dependent changes in biphasic EMG activity. Similar modulation of the initial rate of rise of the EMG, integrated agonist and antagonist EMG activity, as well as their relative timing were observed in all 4 groups. Those results suggest that older individuals of both genders retain the control strategies for elbow movements used by young individuals. Despite the qualitative similarities in the patterns of muscle activation, the men moved more quickly than the women, and younger participants moved more quickly than older participants. Those performance differences could not be explained in terms of differences in body size and strength alone.     

Cohort Differences in Hand Test Performance: A Time Lagged Analysis

In order to examine the impact of cultural differences (cohort and/or time of measurement) on the intrapsychic processes of older adults, two samples (1976, n = 102; 1986, n = 88) of older persons were compared with regard to their Hand Test (HT; Bricklin, Piotrowski, & Wagner, 1962; Wagner, 1983) performance. Relative to those studies investigating cultural effects in personality at the socioadaptational level (Neugarten, 1977), no research to date has examined this issue utilizing projective methods of assessment. Time-lagged analyses of HT scores of these two samples of elderly adults suggested that there appear to be clear age-related variance in HT performance for both content and derived HT variables. Age-related within-sample variability for most HT scores supported this interpretation. These findings are in contrast to those utilizing more standardized, nomothetic measures of personality functioning that suggest stability of personality in adulthood.     

Conceptual overlap between moral norms and anticipated regret in the prediction of intention: Implications for theory of planned behaviour research

Moral norms and anticipated regret are widely used extensions to the theory of planned behaviour, yet there is some evidence to suggest that these constructs may conceptually overlap as predictors of intention. Two health-related behaviours with distinct moral implications (Study 1: organ donation registration, N?=?352 and Study 2: condom usage, N?=?1815) were therefore examined to ascertain whether moral norms and anticipated regret are indeed conceptually distinct. While evidence consistent with conceptual overlap was identified in Study 1, the evidence for such overlap in Study 2 was more ambiguous. In Study 3, a meta-analysis of existing literature revealed that the relationship between moral norms and anticipated regret was moderated by the extent of the moral implications arising from the behaviour under examination. Taken together, these findings suggest that conceptual overlap between moral norms and anticipated regret is more likely to occur among behaviours with obvious moral implications. Researchers wishing to examine the predictive utility of moral norms and anticipated regret among such behaviours would therefore be advised to aggregate these measures to form a composite variable (personal norms).     

Resolving the theory of planned behaviour's ‘expectancy-value muddle’ using dimensional salience

The theory of planned behaviour is one of the most widely used models of decision-making in the health literature. Unfortunately, the primary method for assessing the theory's belief-based expectancy-value models results in statistically uninterpretable findings, giving rise to what has become known as the ‘expectancy-value muddle’. Moreover, existing methods for resolving this muddle are associated with various conceptual or practical limitations. This study addresses these issues by identifying and evaluating a parsimonious method for resolving the expectancy-value muddle. Three hundred and nine Australian residents aged 18–24 years rated the expectancy and value of 18 beliefs about posthumous organ donation. Participants also nominated their five most salient beliefs using a dimensional salience approach. Salient beliefs were perceived as being more likely to eventuate than non-salient beliefs, indicating that salient beliefs could be used to signify the expectancy component. The expectancy-value term was therefore represented by summing the value ratings of salient beliefs, an approach that predicted attitude (adjusted R ²?=?0.21) and intention (adjusted R ²?=?0.21). These findings suggest that the dimensional salience approach is a useful method for overcoming the expectancy-value muddle in applied research settings.     

Neuropsychological Functioning in Early Hydrocephalus: Review From a Developmental Perspective

Children with hydrocephalus have deficits in several neuropsychological domains. The most notable are motor, visuoperceptual, and visuomotor function. These deficits are multiply determined and depend on the etiology and severity of the hydrocephalus to a large extent. Corpus callosum abnormalities resulting from stretching of callosal fibers and other cortical white matter tracts are implicated as contributory to these deficits. Enlarged ventricles and associated compression of posterior cortical areas also correlate with cognitive impairment. Distinguishing which cognitive domain negatively impacts on the child’s functioning and which domains influence behavior in isolation or in combination has been the subject of numerous studies. Developmentally, we know little about the emergence of neuropsychological functioning in children with hydrocephalus. Study of the effects of hydrocephalus at different stages of development is useful to clinicians and researchers interested in the impact of diffuse neurophysiological damage on cognition in the developing brain. The medical and neuropsychological literature have begun to inform about these effects. The core deficits in hydrocephalus have yet to be explicated and a focus on investigations that answer these questions is required. This review summarizes the current knowledge about neurocognitive sequelae of hydrocephalus.     

Pregnancy complications and neuropsychological outcomes: A review

Pregnancy complications elevate risk of associated adverse medical, socioenvironmental, and behavioral outcomes in children. These are likely to have a substantial impact on neuropsychological functioning and mental health across the child’s lifespan. Thus, an understanding of the complex relationships between pregnancy complications and neuropsychological outcomes is critical for both practitioners and researchers. This review summarizes prevalent pregnancy complications and the associated psychological and neuropsychological findings, highlighting methodological challenges that have restricted investigations of these outcomes and identifying opportune areas for future study.
