The Disgust Scale: item analysis, factor structure, and suggestions for refinement

In the 4 studies presented (N = 1,939), a converging set of analyses was conducted to evaluate the item adequacy, factor structure, reliability, and validity of the Disgust Scale (DS; J. Haidt, C. McCauley, & P. Rozin, 1994). The results suggest that 7 items (i.e., Items 2, 7, 8, 21, 23, 24, and 25) should be considered for removal from the DS. Secondary to removing the items, exploratory and confirmatory factor analyses revealed that the DS taps 3 dimensions of disgust: Core Disgust, Animal Reminder Disgust, and Contamination-Based Disgust. Women scored higher than men on the 3 disgust dimensions. Structural modeling provided support for the specificity of the 3-factor model, as Core Disgust and Contamination-Based Disgust were significantly predictive of obsessive- compulsive disorder (OCD) concerns, whereas Animal Reminder Disgust was not. Results from a clinical sample indicated that patients with OCD washing concerns scored significantly higher than patients with OCD without washing concerns on both Core Disgust and Contamination-Based Disgust, but not on Animal Reminder Disgust. These findings are discussed in the context of the refinement of the DS to promote a more psychometrically sound assessment of disgust sensitivity.     

Assessment of Disgust Sensitivity in Children With an Age-Downward Version of the Disgust Emotion Scale

The present study examined the psychometric properties of the Disgust Emotion Scale for Children (DES-C). Principal components analysis of the DES-C data revealed five factors reflecting disgust toward (a) rotting foods, (b) injection and blood, (c) odors, (d) mutilation and death, and (e) animals, which were largely in keeping with the intended subscales. The DES-C showed good reliability, excellent convergent validity (as established by correlations with an alternative self-report index of disgust), fairly good predictive validity (as assessed by correlations with measures of fear/anxiety and a behavioral index of disgust), and acceptable parent–child agreement (in particular with the mothers). Importantly, the DES-C proved to perform better on some psychometric indicators than an age-downward version of the Disgust Scale. These findings indicate that the DES-C should be regarded as the preferred scale for measuring disgust sensitivity and its role in the etiology and maintenance of anxiety problems in children.     

A taxometric study of the latent structure of disgust sensitivity: converging evidence for dimensionality

Disgust sensitivity has recently been implicated as a specific vulnerability factor for several anxiety-related disorders. However, it is not clear whether disgust sensitivity is a dimensional or categorical phenomenon. The present study examined the latent structure of disgust by applying three taxometric procedures (maximum eigenvalue, mean above minus below a cut, and latent-mode factor analysis) to data collected from 2 large nonclinical samples on 2 different measures of disgust sensitivity. Disgust sensitivity in the first sample (n=1,153) was operationalized by disgust reactions to food, animals, body products, sex, body envelope violations, death, hygiene, and sympathetic magic, as assessed by the Disgust Sensitivity Scale (J. Haidt, C. McCauley, & P. Rozin, 1994). Disgust Sensitivity Scale indicators of core, animal reminder, and contamination disgust were also examined in the 1st sample. Disgust sensitivity in the 2nd independent sample (n=1,318) was operationalized by disgust reactions to animals, injections and blood draws, mutilation and death, rotting foods, and odors, as assessed by the Disgust Emotion Scale (R. A. Kleinknecht, E. E. Kleinknecht, & R. M. Thorndike, 1997). Results across both samples provide converging evidence that disgust sensitivity is best conceptualized as a dimensional construct, present to a greater or lesser extent in all individuals. These findings are discussed in relation to the conceptualization and assessment of disgust sensitivity as a specific dimensional vulnerability for certain anxiety and related disorders.     

Behavioral correlates of selected MMPI-2 clinical, content, and restructured clinical scales

In this study, we evaluated the validity of the Restructured Clinical (RC; Tellegen et al., 2003) scales by identifying and comparing behavioral correlates of selected RC scales (RCd, RC2, RC4), their original Clinical scale counterparts (Scale 2, Scale 4), and conceptually related Content scales (DEP, ASP, CYN) in an outpatient clinical sample (N = 150). The results of this study indicate that RC4 is a stronger predictor of several antisocial behaviors than Clinical Scale 4 or the Content Scales ASP and CYN. In contrast, RC2 demonstrated significantly lower correlations with several behaviors conceptually related to depression than its Clinical scale counterpart or DEP. DEP was highly correlated with RCd (r = .91, p < .0001), suggesting that the 2 scales may be measuring similar constructs. Overall, the results of this study demonstrate relatively few differences among the scales selected in their ability to predict extratest behaviors.     

The Three Domains of Disgust Scale: factor structure, psychometric properties, and conceptual limitations

This investigation examined the measurement properties of the Three Domains of Disgust Scale (TDDS). Principal components analysis in Study 1 (n = 206) revealed three factors of Pathogen, Sexual, and Moral Disgust that demonstrated excellent reliability, including test-retest over 12 weeks. Confirmatory factor analyses in Study 2 (n = 406) supported the three factors. Supportive evidence for the validity of the Pathogen and Sexual Disgust subscales was found in Study 1 and Study 2 with strong associations with disgust/contamination and weak associations with negative affect. However, the validity of the Moral Disgust subscale was limited. Study 3 (n = 200) showed that the TDDS subscales differentially related to personality traits. Study 4 (n = 47) provided evidence for the validity of the TDDS subscales in relation to multiple indices of disgust/contamination aversion in a select sample. Study 5 (n = 70) further highlighted limitations of the Moral Disgust subscale given the lack of a theoretically consistent association with moral attitudes. Lastly, Study 6 (n = 178) showed that responses on the Moral Disgust scale were more intense when anger was the response option compared with when disgust was the response option. The implications of these findings for the assessment of disgust are discussed.     

Construct validation of a state version of the Social Physique Anxiety Scale among young women

This study examined the validity of a state version of the Social Physique Anxiety Scale (Hart, Leary & Rejeski, 1989) by conducting tests of concurrent and discriminative validation. Participants were four separate samples of young women (N=221) who exercised ≤ 2 days/week and who participated in various experiments examining body image and self-presentation. Participants' scores on the state SPAS (S-SPAS) were significantly correlated, in expected directions, with scores on both trait and state measures of body image and self-presentation, and with body mass index (BMI). In addition, S-SPAS scores discriminated between women who exercised in a mixed-sex versus a same-sex environment, but trait SPAS scores did not. Together, these results provide evidence of construct validity of a state version of the SPAS and demonstrate that social physique anxiety can be conceptualized and measured as a situational variable. The S-SPAS, rather than the trait SPAS, should be employed in experiments designed to detect differences in state social physique anxiety.     

Psychometric properties of a European Spanish version of the Perceived Stress Scale (PSS)

This paper presents evidence from a heterogeneous sample of 440 Spanish adults, for the reliability and validity of a European Spanish version of the Perceived Stress Scale (PSS), designed to measure the degree to which situations in one's life are appraised as stressful. The European Spanish version PSS (14-item) demonstrated adequate reliability (internal consistency, alpha = .81, and test-retest, r = .73), validity (concurrent), and sensitivity. Additional data indicate adequate reliability (alpha = .82, test-retest, r = .77), validity, and sensitivity of a 10-item short version of the PSS.     

The Transportation Scale–Short Form (TS–SF)

One popular concept to capture the experience of being immersed into the world of a story is that of transportation. This article examines the factorial validity of the Transportation Scale (TS) and introduces a short and psychometrically sound alternative for the assessment of transportation. Exploratory bifactor modeling in Study 1 (N = 179) provided support for the hypothesized factor structure of the original TS with three facets and a general transportation factor. Based on these analyses, a six-item short version of the scale, the Transportation Scale–Short Form (TS–SF), was developed. Study 2 (N = 131 and N = 246) as well as Study 3 (N = 301) corroborated the short form's factorial structure, reliability, and validity.     

Eating behaviour, body image, and self-esteem of adolescent girls in Malaysia

This cross-sectional study was undertaken with 489 secondary school girls, ages 15-17 years, to examine disordered eating behaviours of adolescent girls in Malaysia and to estimate associations with body weight, body-size discrepancy, and self-esteem. Dietary restraint, binge eating, body image, and self-esteem were assessed using the Restrained Eating scale of the Dutch Eating Behaviour Questionnaire, the Binge Scale Questionnaire, the Contour Drawing Rating Scale, and the Rosenberg Self-Esteem Scale, respectively. Pearson correlations estimated associations between variables. There were 3.1% underweight, 9.8% at risk of being overweight, and 8.6% overweight girls. A total of 87.3% were dissatisfied with their own body size. Dietary restraint and binge eating were reported by 36.0% and 35.4%, respectively. Body Mass Index (r = .34, p < .01) and body-size dissatisfaction (r = .24, p < .01) were significantly associated with dietary restraint and binge eating, but self-esteem (r = -.20, p < .001) was significantly associated only with binge eating.     

Individual Differences in Disgust Sensitivity: Comparisons and Evaluations of Paper-and-Pencil versus Behavioral Measures

Sixty-eight undergraduate students experienced 32 hands-on tasks designed to provide a behavioral validation for the paper-and-pencil Disgust Scale, which the students had completed 2 months before. Tasks assessed participant-determined degree of exposure (looking at, picking up, touching, and in some cases eating) to objects such as a cockroach, cremated ashes, and a freshly killed pig's head and to disgusting video clips (seconds watching). These tasks elicited strong negative affect in a way that was ethical and not very disturbing to participants; they may be useful for future laboratory study of emotion. Participants also experienced nondisgusting control tasks, such as imitating a chicken or holding one's hand in ice-water. Analysis of task intercorrelations indicated four factors: food-related disgust, body-violation-and-death-related disgust, compliance motivation, and embarrassability. Only the two disgust factors correlated significantly with the paper-and-pencil Disgust Scale; a combination of the two correlated .58 with Disgust Scale scores obtained months before the laboratory assessment and correlated .71 with scores obtained immediately after this assessment. Most generally, these results are a reminder that there is no gold standard for personality assessment. As with paper-and-pencil measures, behavioral measures require getting beyond face validity to assess threats to validity from factors such as embarrassment and compliance motivation.     

Psychometric properties of the Norwegian version of the Dysfunctional Attitude Scale (Form A)

The present study reports the reliability and validity of the Norwegian version of the Dysfunctional Attitude Scale in non-clinical and clinical populations. The participants were 344 young male military recruits, 41 healthy controls and 142 psychiatric outpatients. All the participants completed the Dysfunctional Attitude Scale, the Beck Depression Inventory and the Automatic Thoughts Questionnaire. The analysis of the Dysfunctional Attitude Scale revealed a Cronbach's alpha of 0.85, indicating satisfactory reliability. Evidence for the construct validity was obtained by the correlation between the Dysfunctional Attitude Scale and the Beck Depression Inventory (r = 0.47) and the Dysfunctional Attitude Scale and the Automatic Thoughts Questionnaire (r = 0.47). Finally, the Dysfunctional Attitude Scale significantly discriminated between clinically depressed, non-depressed psychiatric patients and healthy controls. The results showed that the Norwegian version of the Dysfunctional Attitude Scale possess satisfactory psychometric properties suggesting that this instrument is appropriate for use as a cognitive measure in a Norwegian cultural context.     

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.     

The moral justification scale: reliability and validity of a new measure of care and justice orientations

Research increasingly suggests that there are limitations to Kohlberg's theory of moral development. Gilligan in particular has observed that Kohlberg's theory considers abstract principled reasoning as the highest level of moral judgment, and penalizes those who focus on the interpersonal ramifications of a moral decision. Gilligan calls these justice and care orientations. The present paper describes the development of the Moral Justification Scale, an objective measure of the two orientations. The scale consists of six vignettes, of which two are justice oriented, two are care oriented, and two are mixed, incorporating both orientations. Construct validity was evaluated by expert judges and, overall, was high. Cronbach's alpha was .75 for the Care subscale and .64 for the Justice subscale, indicating adequate internal consistency. Split-half reliabilities were as follows: Care, r = .72, p < .01, and Justice, r = .60, p < .05. Regarding test-retest reliability (approximately two weeks), r = .61, p < .05, for Care; r = .69, p < .05, for Justice. Neither subscale correlated significantly with the Marlowe-Crowne Social Desirability Scale. Thus, the Moral Justification Scale shows promise as an easily administered, objectively scored measure of Gilligan's constructs of care and justice.     

Sex differences and sex similarities in disgust sensitivity

Across two studies, we test for sex differences in the factor structure, factor loadings, concurrent validity, and means of the Three Domain Disgust Scale. In Study 1, we find that the Three Domain Disgust Scale has indistinguishable factor structure and factor loadings for men and women. In Study 2, we find a small sex difference in sensitivity to pathogen and moral disgust and a large sex difference in sensitivity to sexual disgust, with women more sensitive to disgust across domains. However, correlations between Three Domain Disgust Scale factors and the five factors and 30 facets of the NEO Personality Inventory were indistinguishable between the sexes. These findings suggest that, despite mean sex differences in disgust sensitivity, the Three Domain Disgust Scale measures similar constructs in men and women. Implications for understanding the constructs measured by the Three Domain Disgust Scale are discussed.     

The criterion validity of the Borderline Personality Features Scale for Children in an adolescent inpatient setting

The purpose of the current study was to examine the criterion validity of the Borderline Personality Features Scale for Children (BPFS-C) by assessing the performance of the self-report and a newly developed parent report version of the measure (BPFS-P) in detecting a borderline personality disorder (BPD) diagnosis in adolescent inpatients. This study also examined parent-child agreement and the internal consistency of the BPFS subscales. An inpatient sample of adolescents (n = 51) ranging from ages 12-18 completed the BPFS and were administered the Child Interview for DSM-IV Borderline Personality Disorder (CI-BPD) by trained clinical research staff. ROC analyses revealed that the BPFS-C has high accuracy (AUC = .931; Se = .856; Sp = .840) in discriminating adolescents with a diagnosis of BPD, as measured by the CI-BPD, while the BPFS-P has moderate accuracy (AUC = .795; Se = .733; Sp = .720). Parent-child agreement on total scores was significant (r = .687; p < .005). Cronbach's alphas suggested internal consistency for the four subscales of the BPFS. These findings support the criterion validity of this measure, particularly the self-report version, in adolescent inpatient settings.     

Validation of the 'How I Think Questionnaire' in a population of French-speaking adolescents with externalizing behaviors

'How I Think Questionnaire' (HIT) is used to measure self-serving cognitive distortions among delinquents. Previously validated on Americans, this instrument was translated, adapted and validated for French-speaking teens. To assess convergent and discriminant validity, 336 adolescents with externalizing behaviors in Québec (Canada) completed the HIT, the Self-Reported Delinquency Scale (SRD), and the Auto-aggression Questionnaire. There were 165 boys and 171 girls with M(age) = 16.4 years (SD = 0.5) who received services under the Youth Criminal Justice Act (n = 145) or the Youth Protection Act (n = 191). HIT and SRD total scores were correlated (0.51, p < 0.01). On the HIT, past suicidal attempting delinquents were not significantly different than non-suicide attempting delinquents; also delinquents living in closed detention facilities had more self-serving cognitive distortions than delinquents living in open facilities or under probation in the community. This French-language version of the HIT is a reliable and valid measure.     

Case Studies of Two Schizophrenic Patients

A recent meta-analysis found that the Rorschach Prognostic Rating Scale (RPRS) had a strong ability to predict subsequent outcome (r = .44, N = 783; Meyer &; Handler, 1997, this issue). However, that review did not directly address questions of incremental validity. This article focuses on the ability of the RPRS to predict outcome after taking into account other sources of data. Across studies that examined both the RPRS and the MMPI Ego Strength scale, the RPRS had a strong ability to predict outcome (r = .40, N = 187), whereas the MMPI scale did not (r = .02, N = 280). Nine studies examined the RPRS along with an intelligence test and allowed direct numerical estimates of incremental validity to be calculated. Across studies, the RPRS demonstrated strong incremental validity after controlling for intelligence (incremental r = .36, N = 358). It is clear that the Rorschach can make unique contributions to understanding clinically relevant processes in ways that self-reports or measured intelligence cannot. Contemporary Rorschach scales should continue to be evaluated for their distinctive and incremental contribution to clinical practice.     

The Assessment of Marital Adjustment with Chinese Populations: A Study of the Psychometric Properties of the Dyadic Adjustment Scale

This article presents findings from a study of the psychometric properties of the Dyadic Adjustment Scale (DAS) with 63 Chinese-Americans. The analysis revealed high internal consistency for DAS scores. Coefficient alpha for the total DAS score was r = .93. Convergent validity was established with the Locke-Wallis Marital Adjustment Scale (LWMAT) (r = .87) and divergent validity by evidence of an inverse relationship with the Marital Disaffection Scale (MDS) (r = –.79). Correlations with each measure were found to be (p = 0.01). The result of factor analysis fail to support the presence of four separate subscales. Results show that the global DAS score is of potential utility with Asian samples.     

Incremental validity of the Rorschach Prognostic Rating Scale over the MMPI Ego Strength Scale and IQ

A recent meta-analysis found that the Rorschach Prognostic Rating Scale (RPRS) had a strong ability to predict subsequent outcome (r = .44, N = 783; Meyer & Handler, 1997, this issue). However, that review did not directly address questions of incremental validity. This article focuses on the ability of the RPRS to predict outcome after taking into account other sources of data. Across studies that examined both the RPRS and the MMPI Ego Strength scale, the RPRS had a strong ability to predict outcome (r = .40, N = 187), whereas the MMPI scale did not (r = .02, N = 280). Nine studies examined the RPRS along with an intelligence test and allowed direct numerical estimates of incremental validity to be calculated. Across studies, the RPRS demonstrated strong incremental validity after controlling for intelligence (incremental r = .36, N = 358). It is clear that the Rorschach can make unique contributions to understanding clinically relevant processes in ways that self-reports or measured intelligence cannot. Contemporary Rorschach scales should continue to be evaluated for their distinctive and incremental contribution to clinical practice.
