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.     

Construct validity of the helplessness/hopelessness/haplessness scale: correlations with perfectionism and depression

In a sample of 117 undergraduates, helplessness scores and the discrepancy scores on a measure of perfectionism predicted depression scores, providing evidence for construct validity for the hopelessness, helplessness, and haplessness scales.     

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 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.

Construct validity of the Vividness of Visual Imagery Questionnaire

Chara (1989) recently questioned the construct validity of the Vividness of Visual Imagery Questionnaire (VVIQ) on empirical grounds. Unfortunately, Chara in that paper has erroneously construed construct validity as independent of criterion-related validity. This error is compounded by Chara and Verplanck's 1986 assumption that the VVIQ assesses purely memory imagery. Further problems arise from Chara's 1989 selective reporting of the relevant literature. Comprehensive review of the VVIQ literature in its totality is necessary before conclusions are possible concerning the questionnaire's construct validity.     

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 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 of the Kendrick Battery with institutionalized aged

In this study, we attempted to explore the construct validity of the Kendrick Battery by using an American sample and psychometric tests as indexes of diffuse organicity, depression, and normality. Institutionalized residents (N = 53) were tested twice (6-week interval). When organicity was defined by disorientation and memory deficits, then both the Object Learning test and the Digit Copying test were accurate in differentiating preestablished criterion groups. When organicity was defined more broadly, including sensorimotor function, the Digit Copying test alone was more accurate when depression was defined in terms of irritability, restlessness, and despair. These data suggest that although the Kendrick scales appeared to be sensitive to organicity and depression in this sample, their validity varied with the criteria for each when such were defined psychometrically.     

Construct validity of repression: a dimensional analysis

This study explored the construct validity of repression through an examination of the interrelations among indicators identified in previous research as being associated with the construct. Three behavioral tasks, i.e., dichotic listening task, recall of past events task, and Stroop task, modified in accordance with previous research to tap into repressive tendencies, and one questionnaire (Byrne Repression-Sensitization Scale) were administered to a sample of 62 university undergraduates. A series of correlational analyses provided weak to moderate support for the construct validity of repression.     

Construct validity of the Holtzman Inkblot Anxiety and Hostility scores

The group version of the Holtzman Inkblot Technique (HIT), the IPAT Anxiety Scale Questionnaire (ASQ), the Manifest Hostility Scale (MHS), and the Hand Test (HT) were administered to 72 college subjects in an attempt to clarify the nature of the HIT Anxiety (Ax) and Hostility (Hs) scores. The Ax score was found to correlate significantly with the ASQ total score which represents both overt and covert anxiety. The Hs score was found to correlate significantly with the MHS, which is sensitive to moderate levels of verbal hostility, but not with the HT Acting Out Ratio (AOR), which is strictly a measure of overt aggressiveness. The HIT Ax and Hs scores were concluded to relate most closely with measures that encompass a wide spectrum of the variable in question.     

Construct and concurrent validity of the Korean Career Indecision Inventory

Construct and concurrent validity of the Korean Career Indecision Inventory were examined. Data were collected from 238 South Korean college students. A confirmatory factor analysis supported the original five-factor model. As hypothesized, scores were significantly correlated with various variables such as scores on the Korean versions of the Career Decision Scale (r =.49), the Vocational Identity Scale in My Vocational Situation (r=-.63), the Career Decision-making Self-efficacy Scale (r=-.47), and Negative Affectivity (r=.37). These results support construct validity inventory. Students who indicated they were undecided about their careers had significantly higher scores than those who indicated they had decided on a career, supporting concurrent validity. Implications and limitations are discussed.     

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 the misrepresentation scales of the psychological screening inventory

This study provides construct validity evidence and reliabilities (consistency and stability) for 5 misrepresentation (response distortion) scales of the Psychological Screening Inventory (PSI; Lanyon, 1970, 1973, 1978) in assessing 3 constructs: exaggeration of psychopathology, exaggeration of personal virtue, and exaggeration of health problems. Using data from forensic cases, the existence and independence of these 3 constructs were confirmed in data from the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) and the Balanced Inventory of Desirable Responding (Paulhus, 1986, 1991). The PSI scales were then shown to load highly on these constructs. The PSI scales also showed the expected patterns when their mean scores were examined for 15 sets of responses from participant groups with varied motivations to misrepresent. We present receiver operating characteristic data to show the success of the scales in distinguishing between simulators and appropriate comparison groups. Using the same data, we also present classification accuracy in terms of positive predictive power and negative predictive power based on a sensitivity level of 90% and misrepresentation base rates of .20 and .10.     

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.
