Kinesthetic aftereffect and personality: a case study of issues involved in construct validation.

Kinesthetic Aftereffect (KAE), once a promising personality index, has been abandoned by many investigators because of poor retest reliability and intermittent validity. In challenging this current consensus, we argue that (a) first-session KAE is valid; (b) poor retest reliability simply reflects later-session bias; (c) hence, multisession studies should not be used to assess validity without taking this bias into account. Those recent studies which failed to support KAE validity were each multisession in design. If our bias contention is correct, these studies should be ignored, and the claim of intermittent validity is thus rebutted. Reanalysis of the most recent major multisession, nonsupportive validity study indicates (a) Session 1 validity, (b) later-session bias, and (c) later-session valdiity when multisession scores are combined to avoid bias. Thus, KAE validly measures personality.

What's so unhealthy about hostility? Construct validity and psychosocial correlates of the Cook and Medley Ho scale.

The Cook and Medley (1954) Hostility (Ho) scale, a measure of hostility derived from the Minnesota Multiphasic Personality Inventory (MMPI), was recently found in one cross-sectional study to be related to the severity of coronary artery disease and in two prospective studies to predict the development of coronary heart disease. Unfortunately, little information is available to clarify the meaning of the scale, and little is known about the psychosocial characteristics of individuals with high Ho scores. As a result, interpretation of the previous studies is difficult. Our two studies attempted to address these concerns. In Study 1, the Ho scale demonstrated convergent and discriminant validity. Data indicated that the scale primarily assesses suspiciousness, resentment, frequent anger, and cynical distrust of others rather than overtly aggressive behavior or general emotional distress. In Study 2, individuals with high scores displayed comparatively more anger, less hardiness, more frequent and severe hassles, and fewer and less satisfactory social supports. Thus, we propose that the Ho scale assesses cynical hostility and conclude that high scores are associated with a particularly unhealthy psychosocial risk profile. These findings refine our understanding of the Ho scale and assist in the interpretation of previous studies using this measure.

Reliability, performance characteristics, construct validity, and an initial clinical application of a visual object learning test (VOLT).

Whereas verbal learning has received considerable attention by cognitive neuropsychology, spatial object learning has been more resistant to study. The paucity of visual learning data has hampered attempts to clarify if visual learning has unique features with specialized neural substrates. In schizophrenia, severe verbal learning impairment has been established, but lack of comparable visual learning measures has thwarted the dissociation of verbal and visual abilities. The Visual Object Learning Test (VOLT) was developed to examine aspects of visual-spatial learning and memory in a manner analogous to available verbal tests. Studies were performed to establish normative performance characteristics, convergent and divergent validity, and the sensitivity of the VOLT to detection of individual differences in normal (through sex and age) and pathologic variability (through persons with schizophrenia). The results indicated excellent internal consistency, convergent and divergent validity, and sensitivity to the effects of aging and pathology. Persons with schizophrenia were impaired in both learning and retention. The authors conclude that memory impairment in schizophrenia may not be specific to verbal learning.

Diagnosing attention deficit disorders with the Behavioral Assessment System for Children and the Child Behavior Checklist: test and construct validity analyses using optimal discriminant classification trees.

The usefulness of the Behavioral Assessment System for Children (BASC) and Child Behavior Checklist (CBCL) Parent scales was examined with respect to (a) differentiating students with attention deficit-hyperactivity disorder (ADHD) from non-ADHD students and (b) discriminating between the predominantly inattentive-type and combined-type ADHD-afflicted students. For both the BASC and the CBCL, a different optimal discriminant classification tree analysis (CTA) model was developed for each of the 2 diagnostic predictions. For distinguishing ADHD students from non-ADHD students, the BASC model was more parsimonious and accurate than the CBCL model. Toward the goal of differentiating between primarily inattentive and combined types, the CBCL's model was superior for predicting primarily inattentive students. The results demonstrate the diagnostic utility of the BASC and CBCL and describe salient behavioral dimensions associated with subtypes of ADHD.

Prediction of clinical course by dexamethasone suppression test (DST) response in depressed patients - physiological and clinical construct validity of the DST.

The present survey highlights the rationale for the use of state-dependent biological markers as predictors of clinical course in depression. Cortisol plasma levels after dexamethasone provide such a tool to monitor clinical progress. Since dexamethasone-resistant cortisol gradually returns to normalcy before a complete clinical remission is seen this measure has a possible predictive potential. Moreover, reversion to abnormal dexamethasone responses is prognostically infaust. Though the dexamethasone test has some merits, technical factors (e.g. exclusion criteria, dexamethasone-kinetics) which invalidate test results deserve careful consideration in future studies. Cortisol hypersecretion is considered as a physiological readout of a central disinhibition. This hypothesis is tested applying corticotropin-releasing factor and corticotropin in normal and abnormal DST responders. The data support the validity of the concept which assumes an intact but overactive pituitary-adrenal axis in a depressed subpopulation. A thesis is submitted which places the variety of biological disturbances in depression between two extreme viewpoints. One view considers all biological disturbances as sequelae to one particular dysfunction, e.g. disinhibition of corticosteroid secretion. The opposite view considers the myriad of biological disturbances as a sign of general loss of order, i.e. increased entropy, the precipitating mechanism of which is unknown.

Construct validity of the Dissociative Experiences Scale: II. Its relationship to hypnotizability.

Undergraduates (n = 311) who volunteered to participate in an experiment on "Hypnotizability and Personality" filled out several personality questionnaires (including the Dissociative Experiences Scale; DES), were administered the Harvard Group Scale of Hypnotic Susceptibility (HGSHS), and completed a self-rating of hypnotizability. The DES overall score correlated significantly with the HGSHS summary score (r(309) = .12, p < .05, two-tailed) and with subject's self-rating of hypnotizability (r(309) = .13, p < .05, two-tailed). The magnitude of these correlations was similar to that observed in a previous study (.14 & .18) and is also similar in magnitude to the correlations typically observed between the HGSHS and the Tellegen Absorption Scale. The potential clinical implications of these findings are discussed.
