Construct validity of Wechsler factor scores.

The construct validity of the Verbal Comprehension. Perceptual Organization, and Freedom from Distractibility factor scores was examined in a sample of school-aged referred children. Examination of correlations between factor scores and neuropsychological and achievement tests generally supported the construct validity of the factors. The Verbal Comprehension factor was associated with verbal, quantitative, and concept-formation abilities. The Perceptual Organization factor was related to nonverbal concept formation, tactual performance, and visual attention. The Freedom from Distractibility factor demonstrated a complex pattern of correlations and appeared to reflect a range of abilities including quantitative, language, attentional, and concept formation.     

Construct validity and case validity in assessment

Clinical assessment relies on both construct validity, which focuses on the accuracy of conclusions about a psychological phenomenon drawn from responses to a measure, and case validity, which focuses on the synthesis of the full range of psychological phenomena pertaining to the concern or question at hand. Whereas construct validity is grounded in understanding causal influences of a distinct phenomenon on responses to various measures and life contexts, case validity encompasses the joint influences of multiple phenomena on individuals' responses. Two sets of distinctions essential to understanding psychological phenomena, hence to understanding construct validity, are (a) implicit and explicit versions of personality constructs and (b) ability and personality as versions of constructs measured by performance tests presenting maximal and typical conditions, respectively. Since both implicit and explicit versions of constructs interface with maximal or typical performance conditions, case validity requires systematic inclusion of these distinctions in assessment protocols.     

Improving the validity of global ratings

To examine the effects of behavior sampling on global ratings, four groups of 10 teachers each received varying amounts of observation training, practice, and feedback. Teachers viewed a series of seven videotapes depicting two boys whose percentage of distractible behavior was systematically manipulated. Ratings of distractibility were obtained for each taped vignette. Results showed that teachers who received observation training and who routinely collected data in their own classroom submitted ratings which corresponded to actual levels of distractible behavior. Teachers who received no training, or who were trained but did not practice, submitted ratings that were significantly less accurate.This research was supported by the Molson Foundation, Montreal, Quebec, Canada.     

Construct validity and content analysis

We clarify points of agreement and disagreement with Schnurr, Rosenberg, and Oxman, as put forth in their article appearing this issue. Speech samples elicited under different conditions may or may not be interchangeable. This is a matter of empirical research, but it is also dependent upon the meaningfulness of the content categories. used in the analysis. We prefer a theory-driven, construct validational approach that employs well validated coding schemes to assess psychologically meaningful concepts.

Substance use risk across three generations: the roles of parent discipline practices and inhibitory control.

This study used 3 generations and 21 years of prospective data to test models of intergenerational transmission of substance use and substance use risk. Thus, the study extends prior studies in the field that have focused predominantly on substance abuse. The association between the grandparental generation's (G1 mother and father) and the parental generation's (G2 father) alcohol use and illicit drug use was hypothesized to be mediated by G2's poor inhibitory control. Additionally, G1's poor discipline of G2 was hypothesized to be directly associated with G2's substance use as well as to partially mediate the association between G1's substance use and G2's inhibitory control. In turn, G2's substance use in late adolescence was expected to be associated with its offspring's (G3) poor inhibitory control at age 3 years. Findings partially supported the predictions and varied by substance. For alcohol use, only cross-generational associations in use were found. For illicit drugs, both poor inhibitory control and poor discipline played some mediational role in cross-generational use.     

Construct validity of the Rosenzweig Picture-Frustration Study

Projective and semiprojective techniques are both tools and tests. A schema for assessing the validity of projective devices is proposed: (1) Primary, consisting of (a) construct validity i.e., the soundness of the techniques vis-a-vis its underlying concepts; and (b) criterion-related validity, i.e., the concordance between tool results and specified external criteria. (2) Secondary, viz., pragmatic validity, i.e., the usefulness of the instrument in applied fields. Discussion then focuses on the construct validity of the conceptually-based, semiprojective Rosenzweig P-F Study. specifically the evidence on (a) the self-consistency of its conceptual dimensions; (b) the sequential. social development of the Types and Directions of Aggression; (c) levels of behavior elicited; (d) sensitivity to scorable changes after induced frustration: and (e) physiological correlates oft he aggression categories. In each of these areas evidence exists in support of the validity of the P-F Study.     

Construct validity of the Life Orientation Test

The Life Orientation Test (LOT; Scheier & Carver, 1985) is a common measure of optimism. Previous studies of the convergent and discriminant (vis-à-vis neuroticism) validity of the LOT have relied solely on questionnaires. Our Study 1 was a multitrait, multimethod investigation of the LOT incorporating Gottschalk and Gleser's (1969) method of content analysis of speech samples as a nonquestionnaire assessment method. The LOT did not correlate significantly with the Gottschalk Hope Scale (Gottschalk, 1974) derived from speech samples. Study 2 was an initial attempt to determine the nature of the differences between these alternate measures of optimism. In particular, it was hypothesized and found that the LOT was more fakable than the Hope Scale. Participants who received special instructions to "fake good" scored significantly higher on the LOT than did control participants who received no special instructions. Faking instructions did not significantly affect scores on the Hope Scale.     

Construct validity of voluntary and involuntary absenteeism

Construct validity of voluntary and involuntary employee absenteeism is examined in this study. Canonical correlation analysis of absenteeism measures and organizational, personal and attitudinal variables is used to assess empirically the discriminant validity of voluntary and involuntary absenteeism. The empirical results provide evidence consistent with the interpretation that voluntary and involuntary absenteeism are distinct constructs that are associated differentially with subsets of organizational, personal and attitudinal variables. Further study of causal absenteeism models that include voluntary and involuntary absenteeism constructs and organizational, personal and attitudinal variables is needed to more clearly explicate the antecedents of absenteeism.Research support for Collin J. Watson was provided by a Faculty Fellow Research Award from the University of Utah Research Committee, a Graduate School of Business Research Award, and a sabbatical leave.     

Construct validity and age sensitivity of prospective memory

We administered four prospective memory tasks to 330 adults between 18 and 89 years of age to investigate the relationship among the measures of performance in the four tasks, as well as the relationship of the prospective memory measures to age, other cognitive abilities, and noncognitive factors. The four prospective memory variables were found to exhibit both convergent and discriminant validity, indicating that prospective memory ability appears to represent a distinct dimension of individual differences. The prospective memory construct was significantly related to other cognitive abilities, such as executive functioning, fluid intelligence, episodic memory, and perceptual speed, but it was only weakly related to self-ratings of (primarily retrospective) memory and to personality traits. Although a substantial proportion of the age-related variance on the prospective memory construct was shared with other cognitive abilities, we also found some evidence of unique, statistically independent, age-related influences on prospective memory.     

Construct validity of four basic Vocational Interest factors

To find evidence of the generalizability of four interest factors established for tests within the Roe-Holland framework, factor scores derived from a Vocational Interest Inventory grounded in Roe's system were correlated with the empirically based Strong-Campbell Occupational scale scores. For this sample of 300 counseling clients, a majority of the hypothesized relations were found, and arranging the occupations along these bipolar dimensions both sharpened the definitions of the factors and provided an additional interpretive aid for counseling.     

Construct validity of the Concern For Appropriateness scale

Construct validity of the Concern For Appropriateness scale (CFA; Lennox & Wolfe, 1984), a measure of the tendency to adopt protective self-presentation styles, is examined using a multitrait-multimethod approach. Self-ratings on the CFA and ratings by suitemates constitute the two methods, and concern for appropriateness, interpersonal trust, and boredom susceptibility are assessed with each. Multitrait-multimethod analysis shows that the CFA scale exhibits convergent validity against peer ratings and discriminant validity against boredom susceptibility, the only other variable demonstrating convergence. Results indicate that the CFA exhibits construct validity and might therefore prove useful as an operationalization for self-presentation tendencies.
