The MCMI as a measure of DSM-III

The Millon Clinical Multiaxial Inventory (MCMI) has been interpreted as a measure of DSM-III disorders. However, the MCMI was constructed and validated primarily as a measure of Millon's (1969, 1981) taxonomy, not DSM-III. Comparison of the two taxonomies and examination of the MCMI's content validity for two of the MCMI scales indicate only a partial congruence between the Millon and DSM-III taxonomies. There has been no published empirical research concerning the relationship between the MCMI and DSM-III, and the derivation and cross-validation research for the MCMI scales employed Millon's taxonomy and not DSM-III. It is suggested that until such data have been presented one should be cautious in one's interpretation of the MCMI as a measure of DSM-III disorders.     

The relationship between the MCMI personality scales and DSM-III, axis II

Compared were the personality scales of the Millon Clinical Multiaxial Inventory (MCMI) to the diagnosis of personality disorder, according to the Diagnostic and Statistical Manual of Mental Disorders (3rd ed. [DSM-III]; American Psychiatric Association, 1980), obtained by means of the Structured Interview for the DSM-III Personality Disorders (SIDP). The results from 272 psychiatric outpatients show a good correspondence for the Avoidant and the Dependent scales, a fairly good correspondence for the Schizotypal, the Histrionic, the Borderline, the Narcissistic, and the Paranoid scales, and no correspondence for the Schizoid, the Passive-Aggressive, and the Compulsive scales. The Passive-Aggressive scale seems to be positively correlated to personality disorders in general, whereas the Compulsive scale seems to be negatively correlated to a number of personality disorders.     

The convergent and discriminant validity of subjective fit perceptions

This study examined whether employees develop perceptions about 3 different types of fit: person-organization fit, needs-supplies fit, and demands-abilities fit. Confirmatory factor analyses of data from 2 different samples strongly suggested that employees differentiate between these 3 types of fit. Furthermore, results from a longitudinal design of 187 managers supported both the convergent and discriminant validity of the different types of fit perceptions. Specifically, person-organization fit perceptions were related to organization-focused outcomes (e.g., organizational identification, citizenship behaviors, turnover decisions), whereas needs-supplies fit perceptions were related to job- and career-focused outcomes (e.g., job satisfaction, career satisfaction, occupational commitment). Although demands-abilities fit perceptions emerged as a distinct construct, they were not related to hypothesized outcomes (e.g., job performance, raises).     

The Body Esteem Scale: a convergent and discriminant validity study

This research was intended to further establish convergent and discriminant validity for a recent Body Esteem Scale (BES) which measures different dimensions of body satisfaction in young adults. One hundred and fifty-four male and 193 female undergraduates completed the BES, the Body Consciousness Questionnaire (BCQ), the Self-Esteem Scale, and several questions pertaining to exercise, food intake, and attractiveness. Good convergent and discriminant validity was demonstrated by the Male Upper Body Strength and Physical Condition subscales and by the female Weight Concern, Physical Condition, and Sexual Attractiveness subscales.     

The convergent and discriminant validity of the Need for Cognition Scale

This article reports two studies that examined the convergent and discriminant validity of the Need for Cognition Scale (Cacioppo & Petty, 1982). Using samples of college students and prison inmates, need for cognition scores were found to be positively associated with measures of self-esteem, masculine sex role attitudes, absorption, and private self-consciousness. Modest negative associations between need for cognition and measures of public self-consciousness and social anxiety were also uncovered. Need for cognition scores were generally unrelated to measures of feminine and androgynous sex role attitudes, shyness, sociability, and loneliness. These findings add further evidence supporting the construct validity of the Need for Cognition Scale and expand our understanding of the construct of need for cognition.     

The MCMI provides a good assessment of DSM-III disorders: the MCMI-II will prove even better

Although the arguments that Widiger, Williams, Spitzer and Frances muster in their appraisal of MCMI-DSM-III relationships appear compelling, the study employed to furnish empirical support for their thesis may be seriously flawed and the item content approach they propose as a validation model is judged logically and psychometrically deficient. A rejoinder with supportive data are presented to demonstrate both the substantive parallels and the clinical concordance that exist between MCMI and DSM-III criteria. On the basis of theory development and ongoing research, a new MCMI-II assessment instrument will be forthcoming. A brief summary of this updated inventory's rationale and empirical grounding is provided.     

The implications of convergent and discriminant validity data for instrument validation

It seems intuitively compelling to many investigators that measurements, on the same subjects by different methods, purportedly of the same given trait are somehow better evidenced to be mutually valid measurements of that trait to the degree that they are intercorrelated. It is similarly compelling that measurements on the same subjects of purportedly different and uncorrelated traits are somehow better evidenced to be valid measurements to the degree that they are not intercorrelated. Further, a demonstration of hetero-method mono-trait intercorrelation (convergence) jointly with one of hetero-method, or preferably mono-method, hetero-trait independence (discrimination) is more compelling than either single demonstration alone [see Campbell & Fiske, 1959]. I hope to show in what follows that this intuition is misleadingunless certain rather demanding prerequisites are satisfied. Then I hope to show that contrary demonstrations are generally too indecisive to consitute validity disconfirmations. Finally, I shall consider some issues in the practical use of the indecisive multitrait-multimethod data.An earlier version of this paper was presented at the Midwestern Society of Multivariate Experimental Psychology meetings of May 1969 in Chicago. Some explication of the concept of measuring instrument has also been presented elsewhere [Krause, 1969].     

The MCMI and DSM-III: a brief rejoinder to Million (1985)

Millon (1985) presented eight criticisms of the article by Widiger, Williams, Spitzer, and Frances (1985) on the MCMI as a measure of DSM-III. This article is a brief rejoinder. The major point we wish to make is that one should be cautious in interpreting the MCMI as a measure of DSM-III disorders because there has not yet been any research published on the relationship between the MCMI and DSM-III. We believe this position has not been refuted by Millon's critique.     

The Relationship Between the MCMI Personality Scales and DSM-III,Axis II

Compared were the personality scales of the Millon Clinical Multiaxial Inventory (MCMI) to the diagnosis of personality disorder, according to the Diagnostic and Statistical Manual of Mental Disorders (3rd ed. [DSM-III]; American Psychiatric Association, 1980), obtained by means of the Structured Interview for the DSM-III Personality Disorders (SIDP). The results from 272 psychiatric outpatients show a good correspondence for the Avoidant and the Dependent scales, a fairly good correspondence for the Schizotypal, the Histrionic, the Borderline, the Narcissistic, and the Paranoid scales, and no correspondence for the Schizoid, the Passive-Aggressive, and the Compulsive scales. The Passive-Aggressive scale seems to be positively correlated to personality disorders in general, whereas the Compulsive scale seems to be negatively correlated to a number of personality disorders.     

Empirical clusters of DSM-III personality disorders in violent offenders

Violent male offenders in a maximum security hospital and special units in prisons (N = 164) were interviewed with the Structured Clinical Interview for DSM-III Axis II disorders (SCID-II). Cluster analysis of the personality disorder criteria sets identified six diagnostic patterns: (1) antisocial-narcissistic; (2) paranoid-antisocial; (3) borderline-antisocial-passive-aggressive; (4) borderline; (5) compulsive-borderline; and (6) schizoid. Offenders in the first three groups had more extensive criminal careers, and most were identified as psychopaths by the Psychopathy Checklist-Revised (PCL-R). These Groups also had more frequent lifetime histories of substance abuse. A history of affective and anxiety disorders was more common in Groups 3 and 5, and almost two thirds of Group 2 had a history of psychotic disorder. The results emphasize that dangerous offenders are heterogeneous in personality pathology. They also suggest that personality disorder among violent offenders is more commonly represented by recurring patterns of covarying traits than by single categorical entities proposed in the DSM classification.     

Individual differences in sociosexuality: evidence for convergent and discriminant validity

Individual differences in willingness to engage in uncommitted sexual relations were investigated in 6 studies. In Study 1, a 5-item Sociosexual Orientation Inventory (SOI) was developed. Studies 2, 3, and 4 provided convergent validity evidence for the SOI, revealing that persons who have an unrestricted sociosexual orientation tend to (a) engage in sex at an earlier point in their relationships, (b) engage in sex with more than 1 partner at a time, and (c) be involved in relationships characterized by less investment, commitment, love, and dependency. Study 5 provided discriminant validity for the SOI, revealing that it does not covary appreciably with a good marker of sex drive. Study 6 demonstrated that the SOI correlates negligibly with measures of sexual satisfaction, anxiety, and guilt. The possible stability of, origins of, and motivational bases underlying individual differences in sociosexuality are discussed.     

Comparing borderline definitions: DSM-III borderline and schizotypal personality disorders

Compared the two types of borderline disorder formally defined by DSM-III, borderline personality disorder and schizotypal personality disorder, at the diagnostic category and individual criterion level. Unlike previous research in this area, which has focused on inpatient and outpatient populations, the sample was a psychometrically defined, nonpatient sample including Ss meeting DSM-III criteria for each disorder. The results indicated that the two diagnostic categories each define a type of borderline with distinctive combinations of features. Perceptual and cognitive distortion, however, seem to be present in both and define an area of overlap between the two disorders. The implications of these findings for the revision of the SPD diagnostic criteria in DSM-III-R are discussed, and the theoretical separation of two subtypes of borderline personality is affirmed.     

Evaluation of convergent and discriminant validity with multitrait–multimethod correlations

A procedure for evaluation of convergent and discriminant validity coefficients is outlined. The method yields interval estimates of these coefficients in a construct validation study conducted via the multitrait–multimethod approach, as well as permitting examination of their population relationships. The procedure is readily employed in behavioural research using the increasingly popular latent variable modelling methodology. The method is illustrated with a numerical example.     

Testing the discriminant validity of a four‐dimensional occupational commitment measure

Building on prior work by Blau (2001a, 2001b, 2003) , the results of this study provided some support for a 4‐dimensional measure of occupational commitment ‐ that is, affective, normative and 2 dimensions of continuance commitment, accumulated costs and limited alternatives. Overall, affective commitment showed a stronger relationship to professional withdrawal intentions and to a lesser extent, professional development activities. Accumulated costs interacted with normative commitment such that there was a significant negative relationship of normative commitment to subsequent withdrawal intentions for low accumulated costs. Limited alternatives interacted with normative commitment in a similar way, such that there was a significant negative relationship of normative commitment to subsequent withdrawal intentions for low limited alternatives. However, the similarity of such interactive results, combined with the generally equivalent correlational results of accumulated costs and limited alternatives to other study variables, leads to the alternative speculation that a 1‐factor measure for continuance occupational commitment may be sufficient.     

The redundancy of work alienation and job satisfaction: Some evidence of convergent and discriminant validity

The multitrait-multimethod matrix (MTMM) technique was used in an attempt to help clarify the ambiguities regarding concepts of work alienation, job satisfaction, and the relationships between them. Within each attitude domain considered separately, generally acceptable evidence of convergent and (to a lesser degree) discriminant validity was found for the trait measures (four dimensions of alienation and five of satisfaction). However, the discrimination between alienation and satisfaction measures was no greater than that among satisfaction and among alienation, casting doubt on the demarcation of these as two distinct domains. The measures of satisfaction and alienation also were not correlated differentially with demographic and self-esteem measures. Note was taken of the limitations in our knowledge and operationalization of these areas, as these relate to the assumptions of MTMM technique regarding independence of both underlying trait constructs and measurement methods.     

Convergent and discriminant validity of three measures of depressive personality disorder

Sixty-eight outpatients from a veterans' administration psychiatry clinic and community mental health center were assessed with 3 measures of depressive personality disorder (DPD)-the Diagnostic Interview for Depressive Personality Disorder (Gunderson, Phillips, Triebwasser, & Hirschfeld, 1994), the Depressive Personality Disorder Inventory (Huprich, Margrett, Barthelemy, & Fine, 1996), and the Structured Clinical Interview for DSM-IV Axis II Disorders (First, Gibbon, Spitzer, Williams, & Benjamin, 1997a)-to evaluate their convergent and discriminant validity. Evidence supporting the measures' validity was mixed. The rate of convergence of depressive personality diagnoses across 3 measures was less than optimal, but the degree of intercorrelation among the measures was strong. Although depressive personality scores had moderate levels of intercorrelations with other personality disorders, the degree of intercorrelation decreased substantially after controlling for depressive symptoms. I conclude that further work is needed to strengthen the validity of measures of DPD.     

MMPI scales for DSM-III personality disorders: their derivation and correlates

Scales tapping the dimensions of personality disorder as represented in the DSM-III were derived using a combined rational/empirical strategy. The final version of the scales demonstrated both content validity as well as internal consistency. Correlations between the derived scales and between these scales and the original MMPI clinical scales were generally found to be in the expected direction providing preliminary evidence of criterion related validity. It is suggested that the derived scales may represent an advance toward the reliable assessment of DSM-III personality constructs.
