Discriminant Validity of the General Behavior Inventory: An Outpatient Study

Recent studies have provided strong support for the convergent validity of the General Behavior Inventory (GBI), a case identification inventory for chronic subsyndromal affective disorders (cyclothymia and dysthymia). Fewer data are available, however, on the ability of the GBI to distinguish chronic subsyndromal affective disorders from other forms of psychopathology. In order to address this issue, outpatients with cyclothymia (n = 9), dysthymia (n = 26), nonchronic major depression (n = 16), and nonaffective psychiatric disorders (n = 30) were compared on the GBI. Diagnoses were derived blind to GBI scores using structured diagnostic interviews and DSM-III criteria. The inventory significantly discriminated cyclothymes and dysthymes from patients with nonchronic major depressions and nonaffective disorders. Using the cutoff score that maximized GBI-diagnosis concordance, the inventory correctly classified 88% of the sample. All of the cyclothymes, 92% of the dysthymes, 87% of the patients with nonaffective psychiatric disorders, and 75% of the nonchronic major depressives were correctly classified by the inventory. These data provide strong support for the discriminant validity of the GBI.     

The Reliability,Validity, Discriminant and Predictive Properties of the Social Phobia Inventory (SoPhI)

This paper reports on the psychometric properties of the Social Phobic Inventory (SoPhI) a 21-item scale that was designed to measure social anxiety according to the criteria of DSM-IV (American Psychiatric Association, APA (1994) Diagnostic and Statistical Manual of Mental Disorder , 4th Edn., Washington). Factor analysis of the SoPhI using data from a clinical sample of respondents with social phobia revealed one factor which explained approximately 59% of variance and which demonstrated strong internal reliability ( f = 0.93). The SoPhI demonstrated concurrent validity with the SPAI ( r = 0.86) and convergent validity with the Fear of Negative Evaluations-Revised ( r = 0.68). The predictive utility of the scale was demonstrated in a sample of university students classified as extroverted, normal, shy/introverted, and phobic/withdrawn ( m 2 57%). Multivariate Analysis of Variance (MANOVA) revealed that the combined university sample differed from the clinical sample on the summated scores on the SoPhI and that 43% ( m 2 ) of this difference was attributable to group membership. This figure rose to 58% attributable to group membership when these same groups were compared for differences on the 21 individual items. Scores of the SoPhI that are indicative of concern and of possible diagnostic criteria, as well as suggestions for future research, are discussed.     

On the Discriminant Validity of Burnout,Depression and Anxiety: A Re-examination of the Burnout Measure

We investigated the discriminant validity of the frequently used Burnout Measure (BM) (Pines et al ., 1981), in relation to depressive symptomatology and anxiety. Following Russell's (1980) work on the multidimensional space of affective states, BM's items were hypothesized to reside in three separate regions of that space, labeled anxiety, depression, and wornout, with wornout representing a combination of physical and emotional exhaustion. Respondents were 704 senior army officers, who completed a questionnaire that included BM items, standard measures of depression and anxiety, and measures of military-related stresses. Their responses to the BM items and to the depression and anxiety scales were subjected to multidimensional scaling analysis. Excepting an unexpected finding related to a fourth construct, loss of vigor, the results were supportive of the hypothesis and led to the construction of three unidimensional measures, respectively gauging anxiety, depression, and wornout. The correlations of the three measures with the stress measures supported their discriminant validity. We suggest that future research using the BM should focus on the set of items that were found to load on the dimension of wornout, to the exclusion of items tapping depression and anxiety.     

Measuring Obsessions Without Worry: Convergent and Discriminant Validity of the Revised Padua Inventory in an Icelandic Student Population

The revised Padua Inventory (Padua Inventory-Washington State University Revision or PI-WSUR) was investigated in an Icelandic student population ( n = 431). The inventory was explicitly constructed to minimize the overlap between the measurement of obsessionality and worry. Its relationships with the Maudsley-Obsessive-Compulsive Inventory (MOCI) and the Penn State Worry Questionnaire (PSWQ) were investigated. The factor structure of the PI-WSUR was studied as well as the relations of PI-WSUR subscales with corresponding scales on the MOCI (checking, contamination). It was further investigated whether a factor analysis of the PI-WSUR together with PSWQ would indicate that the PI-WSUR and its different components were relatively uncontaminated by variance shared with worry. The results generally supported the psychometric properties of the Icelandic version of the PI-WSUR as well as its relative independence of PSWQ specifically.     

Lao Depression Inventory

There are no measurement tools that accurately measure depression among Lao refugees. The overall purpose of this research was to complete the development and validation procedures for the Lao Depression Inventory (LDI). The study consisted of 216 Ethnic Lao refugees. A clinical interview and 164 true/false questions were administered to identify specific items which could identify depression among the Ethnic Lao people. All items were administered in both English and Lao. Overall, 78 of the 164 items differentiated groups of depressed and nondepressed Lao at the .01 level. Results of validation procedures showed that a 30-item scale had an accuracy rate of 89% in identifying the presence of depression in the validation group; the hit-rate for the same items and cutoff was 92% in the cross-validation group. Potential uses of the scale are discussed.

The Convergent and Discriminant Validity of the Chapman Scales

Our study investigated the convergent and discriminant validity of five of Chapman's Schizotypia Scales (i.e., Physical Anhedonia, Revised Social Anhedonia, Perceptual Aberration, Magical Ideation, and Impulsive Nonconformity; L. J. Chapman, J. P. Chapman, & Raulin, 1976, 1978; Eckblad & L. J. Chapman, 1983) and Meehl's Schizoidia Scale (Meehl, 1964) within a sample of 50 personality disordered subjects, many of whim possessed schizotypic traits. It was hypothesized in part that all five of the Chapman scales and the Schizoidia Scale would correlate with the schizotypal personality disorder; the Physical Anhedonia and Revised Social Anhedonia Scales would correlate with the schizoid personality disorder, whereas the Magical Ideation and Perceptual Aberration Scales would not; the Physical and Revised Social Anhedonia Scales would not correlate with the avoidant personality disorder; and the Impulsive Nonconformity Scale would correlate with the borderline and antisocial personality disorders. Only the hypotheses concerning the avoidant personality disorder and the Schizoidia Scale were not supported. The findings remained even when the effects of state anxiety and state depression were controlled. Implications of the findings with respect to the validity of the Chapman and Schizoidia Scales and the personality disorders are discussed.     

Validity of the MMPI-2 and Beck Depression Inventory for making decisions of organ allocation in renal transplantation

Psychosocial factors are presented which affect clinical decision-making regarding the allocation of renal organs. Patients were rated as being either High Risk or Low Risk transplant candidates. High Risk candidates were scored as being significantly different from the Low Risk candidates on many psychosocial variables. Interestingly, significant differences were not found between these two groups on either the MMPI-2 or the Beck Depression Inventory. The validity of using information from these inventories to allocate organs is discussed.     

Examination of the Discriminant,Convergent, and Criterion‐Related Validity of Self‐Ratings on the Emotional Competence Inventory

We found that self‐ratings on the Emotional Competence Inventory (ECI) had small relationships with, but a distinct factor structure from, the Big‐Five personality dimensions. ECI self‐ratings were unrelated to academic performance and general mental ability. ECI self‐ratings had significant, albeit small, correlations with EC‐related behaviors and peer nominations of influence during a leaderless group discussion, coworkers' ratings of managerial skills, and number of promotions received. However, with one exception, these significant relationships disappeared after controlling for personality and age.     

Convergent and Discriminant Validity of Five Interest Inventories

This study investigated whether interest inventories that purport to measure the same constructs actually yield scores that correspond. The study examined the empirical relation of scores for similarly and same-named scales on five widely used interest inventories: the Campbell Interest and Skills Survey, the Kuder Occupational Interest Survey-Form DD, the Self-Directed Search, the Strong Interest Inventory-Skills Confidence Edition, and the Revised Unisex Edition of the ACT Interest Inventory. Comparisons were made among scores for (a) vocational interests measured by homogeneous, rationally based scales; (b) occupational interests measured by heterogeneous, criterion-based scales; and (c) self-efficacy for RIASEC tasks. The participants consisted of 80 women and 38 men employed as career counseling practitioners and professors. Results from analyses of multitrait-multimethod matrices indicated that similarly and same-named scales correlated moderately and that, with few exceptions, these matched scales demonstrated convergent and discriminant validity. These conclusions were interpreted by distinguishing between the linguistic explication and operational definition of constructs in theories of vocational and occupational interests. The implications of these interpretations were considered for both the science of vocational psychology and the practice of career counseling. Future research should investigate both the profile validity and the interpretive validity of interest inventories that yield scale scores derived from different scaling strategies.     

Assessing the Current Validity of the Bem Sex-Role Inventory

The Bem Sex-Role Inventory (BSRI) is a widelyused instrument in measuring gender role perceptions.Recent concerns regarding the validity of the adjectiveshave arisen as changes in the roles of men and women have occurred in American society sincethe 1970's. A partial replication of the method that Bem(1974) used to validate the masculine and feminineadjectives comprising the instrument was conducted. All but two of the adjectives were validatedusing Bem's criteria. These findings suggest that theBSRI may still be a valid instrument for assessing genderroles. However, evidence was revealed that traditional masculine and feminine gender role perceptionsmay be weakening. Future validation of the BSRI iswarranted in light of these patterns.     

Discriminant validity of the General Behavior Inventory: an outpatient study

These data provide strong support for the discriminant validity of the GBI.     

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.     

A Hmong Adaptation of the Beck Depression Inventory

We developed the Hmong Adaptation of the Beck Depression Inventory (HABDI) and evaluated the instrument's psychometric characteristics. Also examined was the relationship between depression and demographic variables such as age, sex, length of stay in America, English-speaking ability, and social support in Hmong refugees. One hundred twenty-three Hmong living in Fresno County, between the ages of 18 and 66, participated in the study. The new measure demonstrated a high coefficient alpha (.93), and test-retest reliability (.92), and a significant mean score difference between the nondepressed and the depressed groups. Individual items were distributed evenly and correlated highly with the total depression score. The HABDI correctly identified 94% of depressed and 78% of nondepressed in the Hmong sample. The results suggest that quality of social support and years of education play important roles in buffering Hmong refugees against depression, whereas length of stay in America and number of social supports do not.     

The psychometric characteristics of the Hamilton Depression Inventory

In this study, the psychometric properties of the Hamilton Depression Inventory (HDI; Reynolds & Kobak, 1995a) were examined in a sample of 249 undergraduate participants. The HDI exhibited high internal consistency and support for its construct validity was demonstrated by the HDI's patterns of correlations with other measures of depression, anxiety, and depression-relevant cognition. Factor analyses of the full (23-item) and 17-item versions of the HDI each yielded 4 factors, which accounted for 49% and 53% of the variance in participants' responses, respectively. The utility of the HDI's use of multiple-weighted subitems was also assessed by comparing a less complicated scoring system to the standard scoring format. The standard HDI added significantly to the prediction of criterion indexes after controlling for the variance accounted for by the "simplified" HDI. Moreover, the operating characteristics of the standard HDI outperformed the simplified HDI in the prediction of the Beck Depression Inventory-II (Beck, Steer, & Brown, 1996) classification. The results provide strong support for the HDI as a reliable and valid instrument for the assessment of depressive severity     

TAT Validity: Congruence with an Inventory

To explore what aspect of personality the TAT taps, the TAT responses of 122 healthy, white adults were compared with their scores on the Cattell Sixteen Personality Factor Questionnaire. In Part I major dimensions of the stories were compared with inventory scores. The number of significant correlations were less than expected by chance. In Part II a cross-validation procedure was used with test signs. Half the cases were used to find story characteristics that coincided with an inventory trait score. When these were checked for presence in the second half of the cases, signs held up for the traits of Introversion, Emotional Maturity, Surgency, and Social Sophistication. In Part III inventory scores were predicted from the global study of the TATs of thirty cases, with better than chance success. The Happy-Sad dimension repeatedly had the best inter-test congruence. Intensive case analysis indicated that the TAT shifted in “depth” so that faulty correlations occurred with shallow, conventional stories or overly deep, “ego alien” stories.     

Construct Validity of the Acquired Capability for Suicide Scale: Factor Structure,Convergent and Discriminant Validity

The Acquired Capability for Suicide Scale (ACSS) assesses one of three main constructs in the Interpersonal Theory of Suicide but evidence of its validity is limited. In two studies (Ns = 287 and 738) validity of the full 20-item ACSS and its shorter versions (ACSS-5, ACSS-8, ACSS-FAD) were examined in terms of factor structure and relation to indices of self-reported suicidal behaviour and self-harm. Confirmatory factor analysis (CFA) failed to show good fit for one-, two-, or three-factor models of the ACSS in its various versions. Exploratory factor analysis of the 20-item scale in the first study pointed instead to a five-factor structure and this was supported using CFA in the second study. In both studies all scale versions showed moderate negative correlations to fear of death and dying, indicating scale validity for the purpose of assessing fearlessness about death. In the second study, a model in which the five factors were indicators of a latent variable of Capability was found to predict a latent variable of Suicidality as indicated by suicidal behaviours, but the prediction was substantially enhanced by the addition of Item 20 to the model. This single item was also found in the first study to better predict suicidal and self-harming behaviour than the full ACSS or any of its short versions.     

Predictive Validity of Person Matching at the Scale and Discriminant Analysis Levels

Validity comparisons (including hit rates, kappa coefficients, and chance expectancy rates) were made between person matching at the scale and discriminant analysis levels with 5,143 medical students who had taken an interest inventory and had entered their medical residencies. Person matching using the 30 discriminant analysis items demonstrated the greatest ability to assign test takers to the highest number of occupations at a rate greater than chance.     

An Analysis of the Convergent and Discriminant Validity of the Transformational Leadership Questionnaire

This article sets out to provide evidence of the convergent and discriminant validity of a recently developed leadership questionnaire to support the assessment and development of leadership in organizations, the Transformational Leadership Questionnaire (TLQ). The TLQ was developed on the basis of eliciting constructs of leadership from managers working at different levels (executive, top, senior, middle) in two large parts of the UK public sector, using a Grounded Theory approach. Evidence is presented that eight scales which measure different aspects of transformational leadership are significantly correlated with each of five criterion variables, even when the instrument is used in a public sector different from the one in which it was developed. Discriminant analysis indicated, however, that the relationship between the scales and the criterion variables is not consistent for the different groups and sub-groups of managers, divided by level, by sex, and by level x sex. These latter data were interpreted, in the light of the ‘range of convenience’ corollary of Kelly's Personal Construct Theory, and of the concept of ‘substitutes for leadership’, as evidence that certain TLQ scales have particular relevance to certain groups and sub-groups of managers, and thus of the discriminant validity of the instrument, and further evidence of its construct validity.
