Validating the Eating Disorder Inventory-3 (EDI-3): A Comparison Between 561 Female Eating Disorders Patients and 878 Females from the General Population

The Eating Disorder Inventory (EDI) is used worldwide in research and clinical work. The 3^rd version (EDI-3) has been used in recent research, yet without any independent testing of its psychometric properties. The aim of the present study was twofold: 1) to establish national norms and to compare them with the US and international norms, and 2) to examine the factor structure, the internal consistency, the sensitivity and the specificity of subscale scores. Participants were Danish adult female patients (N = 561) from a specialist treatment centre and a control group (N = 878) was women selected from the Danish Civil Registration system. Small but significant differences were found between Danish and international, as well as US norms. Overall, the factor structure was confirmed, the internal consistency of the subscales was satisfactory, the discriminative validity was good, and sensitivity and specificity were excellent. The implications from these results are discussed.     

Validity of the Eating Disorder Examination Questionnaire (EDE-Q) in screening for eating disorders in community samples

In order to examine the concurrent and criterion validity of the questionnaire version of the Eating Disorders Examination (EDE-Q), self-report and interview formats were administered to a community sample of women aged 18-45 (n = 208). Correlations between EDE-Q and EDE subscales ranged from 0.68 for Eating Concern to 0.78 for Shape Concern. Scores on the EDE-Q were significantly higher than those of the EDE for all subscales, with the mean difference ranging from 0.25 for Restraint to 0.85 for Shape Concern. Frequency of both objective bulimic episodes (OBEs) and subjective bulimic episodes (SBEs) was significantly correlated between measures. Chance-corrected agreement between EDE-Q and EDE ratings of the presence of OBEs was fair, while that for SBEs was poor. Receiver operating characteristic (ROC) analysis, based on a sample of 13 cases, indicated that a score of 2.3 on the global scale of the EDE-Q in conjunction with the occurrence of any OBEs and/or use of exercise as a means of weight control, yielded optimal validity coefficients (sensitivity = 0.83, specificity = 0.96, positive predictive value = 0.56). A stepwise discriminant function analysis yielded eight EDE-Q items which best distinguished cases from non-cases, including frequency of OBEs, use of exercise as a means of weight control, use of self-induced vomiting, use of laxatives and guilt about eating. The EDE-Q has good concurrent validity and acceptable criterion validity. The measure appears well-suited to use in prospective epidemiological studies.     

Psychometric properties of the Spanish version of the Thougth-Shape Fusion Questionnaire

The objectives of the study were to analyze the psychometric properties, factor structure and internal consistency of the Spanish version of the Thought-Shape Fusion Questionnaire (TSF-Q), as well as to determine its validity by evaluating the relationship of the TSF-Q to different instruments. Two groups were studied: one comprising 146 patients with a diagnosis of anorexia (n = 82), bulimia (n = 33) or unspecified eating disorder (n = 31), and another group of 115 undergraduates with no history of psychological disorder. All participants completed the TSF-Q, TAF-Q, EDI-2, STAI, BDI and SCL-90-R. Differences in TSF-Q scores between the diagnostic subgroups were also analyzed. Two factors were obtained which coincided with the two sections indicated by the authors of the questionnaire: conceptual and interpretative. The internal consistency of the TSF-Q and its subscales was determined by means of Cronbach's alpha, with values ranging between .93 and .96. The correlations with other instruments reflected adequate validity. There were no significant differences between the diagnostic subgroups. The Spanish version of the TSF-Q meets the psychometric requirements for measuring thought-shape fusion and shows adequate internal consistency and validity.     

Psychometric properties of the Padua Inventory in Chinese college samples

The aim of the present study was to investigate the psychometric properties of the Padua Inventory in Chinese college samples. Three different samples (N1 = 1,939, N2 = 1,341, and N3 = 298) of Chinese college students were recruited. Exploratory factor analyses yielded a four-factor structure which was similar to that found in previous studies. Further, present results showed good internal consistency as well as convergent and divergent validity with the subscales of the Symptom Checklist-90 and the Penn State Worry Questionnaire. Although no sex difference was found on total score, women had significantly higher scores on Factor 2 (Urges and worries of losing control over motor behaviors) and Factor 4 (Checking), while men had significantly higher scores on Factor 3 (Contamination). Implications of ter the results and directions for research are discussed.     

The reliability and construct validity of scores on the Japanese version of an academic self‐concept scale for a sample of college students1

Abstract: This study investigated the internal consistency, reliability, and construct validity of scores on the Japanese version of the Dimensions of Self‐Concept (DOSC) academic self‐concept scale for a sample of 177 students at a small Japanese private college. Confirmatory factor analyses showed promising support for the construct validity of scores on the six factor subscales (Level of Aspiration, Anxiety, Academic Interest and Satisfaction, Leadership and Initiative, Identification versus Alienation, and Stress), representing the six hypothesized constructs of academic self‐concept. Internal consistency reliability of scores on the six subscales ranged from 0.82 to 0.87.     

When to Use Broader Internalising and Externalising Subscales Instead of the Hypothesised Five Subscales on the Strengths and Difficulties Questionnaire (SDQ): Data from British Parents,Teachers and Children

The Strengths and Difficulties Questionnaire (SDQ) is a widely used child mental health questionnaire with five hypothesised subscales. There is theoretical and preliminary empirical support for combining the SDQ’s hypothesised emotional and peer subscales into an ‘internalizing’ subscale and the hypothesised behavioral and hyperactivity subscales into an ‘externalizing’ subscale (alongside the fifth prosocial subscale). We examine this using parent, teacher and youth SDQ data from a representative sample of 5–16 year olds in Britain (N = 18,222). Factor analyses generally supported second-order internalizing and externalizing factors, and the internalizing and externalizing subscales showed good convergent and discriminant validity across informants and with respect to clinical disorder. By contrast, discriminant validity was poorer between the emotional and peer subscales and between the behavioral, hyperactivity and prosocial subscales. This applied particularly to children with low scores on those subscales. We conclude that there are advantages to using the broader internalizing and externalizing SDQ subscales for analyses in low-risk samples, while retaining all five subscales when screening for disorder.     

Psychometric Evaluation of the Spanish Versions of the Perceived Religious Influence on Health Behavior Scale and the Illness as Punishment for Sin Scale in a Sample of Churchgoing Latinas

The present study evaluated the psychometric properties of the Spanish versions of the Perceived Religious Influence on Health Behavior scale and the Illness as Punishment for Sin scale in a sample of churchgoing Latina women (N = 404). For the Perceived Religious Influence on Health Behavior scale, confirmatory factor analysis provided support for the expected one-factor model, internal consistency reliability was good, and there was evidence of convergent validity. For the Illness as Punishment for Sin scale, confirmatory factor analysis provided support for the expected one-factor model, but on a revised seven-item version of the measure. Internal consistency reliability and convergent validity for this revised version were good. It is recommended that future studies use the Perceived Religious Influence on Health Behavior scale and the revised Illness as Punishment for Sin scale when examining these constructs among Latina women.     

Construct validity of the relationship profile test: three-year retest reliability and links with core personality traits, object relations, and interpersonal problems

The Relationship Profile Test (RPT; Bornstein & Languirand, 2003) is a 30-item self-report measure of destructive overdependence, dysfunctional detachment, and healthy dependency. Previous research has shown that the 3 RPT subscales have adequate internal consistency, good retest reliability over 23 and 85 weeks, and good convergent and discriminant validity with respect to measures of attachment style, relatedness, gender role, self-concept, alexithymia, locus of control, need for approval, and life satisfaction. In this investigation, we assessed the 3-year retest reliability of RPT scores in a northeastern liberal arts college student sample (Study 1) and evaluated the convergent and discriminant validity of RPT scores in a southern university sample (Study 2). Results generally supported the long-term stability and convergent and discriminant validity of RPT scores but also pointed to some limitations of the measure. We discuss implications of these results and describe future research directions.     

Psychometric properties of the Psychological Flourishing Scale in an Egyptian setting

The specific goals of the present research were twofold: i) to test the structure validity, and internal reliability of scores from the Psychological Flourishing Scale (PFS) with Egyptian college students; and ii) to test the PFS’s temporal stability and convergent validity properties. Two samples of Egyptian college students completed the PFS (n = 374; n = 173) to address the two research aims in two studies. The students also completed the Mental Health Continuum-Short Form (MHC-SF) and the Satisfaction With Life Scale (SWLS) for determining the concurrent validity of scores. In the first study, the internal consistency was evaluated. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed. In the second, the temporal stability and convergent validity were tested. The Arabic version of PFS showed a high internal reliability, structure, and convergent validity, and moderate temporal stability.     

Eating disorder examination questionnaire and clinical impairment assessment questionnaire: general population and clinical norms for young adult women in Sweden

Optimal use of assessment instruments for the detection and diagnosis of eating disorders (ED) depends on the availability of normative data. The aim of this work was to, for the first time, collect norms for both the Eating Disorder Examination Questionnaire (EDE-Q) and the newly developed Clinical Impairment Assessment (CIA) Scale from a general population of young women in Sweden, as well as from a clinical population of ED patients in Sweden. Participants were composed of both a randomized sample from the general population of women aged 18–30 years (N = 760) as well as from a clinical population aged 18–66 years (N = 2383). Data for the clinical population was extracted from the Stepwise database. Mean scores, standard deviations and percentile ranks for the global for the EDE-Q (as well as its subscales) and the CIA are presented. Prevalence figures of key eating disorder behaviors are also reported. Comparisons are made between the results in the present study with other existing normative studies on the EDE-Q and the CIA. The present study contributes to improving the accuracy of the interpretation of scores of the widely used self-report measure of ED, the EDE-Q, and the CIA, both of which play important roles in for diagnosis, prevention and intervention of ED.     

Reliability and construct validity of the Japanese version of the interpersonal relationship inventory

The present study examined the psychometric characteristics of the three network function subscales (Social Support, Conflict, and Reciprocity) in the Japanese version of the Interpersonal Relationship Inventory. Data from Japanese college students (250 women and 218 men) were analyzed to estimate internal consistency (alphas = .93-.96) and test-retest reliability (rs = .69-.74). To assess construct validity, correlations between scores on the inventory and measures of social support, loneliness, and stress were performed. Results indicated that the Japanese version of the inventory was valid and reliable.     

Validation of eating disorder examination questionnaire (EDE-Q)--Spanish version--for screening eating disorders

This research examines the internal consistency, convergent validity, and sensitivity, specificity, and positive and negative predictive value of the Spanish version of the Eating Disorder Examination-Self-Report Questionnaire (S-EDE-Q), as a screening questionnaire for eating disorders (ED) in a community sample. Participants were 1543 male and female Spanish-speaking students (age range: 12-21 years), who volunteered to complete the S-EDE-Q and the EAT-40. The Spanish version of the Eating Disorders Examination (S-EDE) interview, 12th edition, was administered to 602 of the students. Acceptable internal consistency for the four subscales of the S-EDE-Q was obtained (alpha > or = .74). Corrected point-biserial correlation performed with the 22 items included in the S-EDE-Q subscales showed acceptable values for all the items. The EAT-40 Dieting subscale correlated highly and positively with the four S-EDE-Q subscales (r > or = .70). Acceptable results in sensitivity, specificity, and positive and negative predictive value when compared with the EDE were found. Correlation between S-EDE and S-EDE-Q diagnoses was positive and significant. Overall, results support the psychometric adequacy of the S-EDE-Q as a screening questionnaire for ED in community samples.     

Comparability of the Eating Disorder Inventory-2 between women and men

Researchers studying eating disorders in men often use eating-disorder risk and symptom measures that have been validated only on women. Using a sample of 215 college women and 214 college men, this article reports on the validity the Eating Disorder Inventory-2 (EDI-2), one of the best-validated among women and the most widely used risk and symptom measure for women. The EDI-2 had the same, standard eight-factor structure for both genders, and tests of invariance showed that factor loadings, factor variances, and factor intercorrelations were equivalent across gender. The EDI-2 scales correlated with questionnaire measures of bulimic and anorexic symptomatology equivalently across gender. However the EDI-2 scales were generally less reliable for men, leading to slightly lower Pearson-based estimates of correlations among the measures for men.     

Eating Disorder Examination Questionnaire (EDE-Q): norms for young adult women

In order to establish norms for the Eating Disorder Examination Questionnaire (EDE-Q) among young adult women, the questionnaire was administered to a large general population sample of women aged 18-42 yr in the Australian Capital Territory (ACT) region of Australia. Normative data were derived for EDE-Q subscales and for the occurrence of specific eating disorder behaviours, for each of five age bands (18-22, 23-27, 28-32, 33-37, 38-42 yr). Mean scores (SDs) for the Restraint, Eating Concern, Weight Concern and Shape Concern subscales for the total sample (n = 5,255) were, respectively, 1.30 (1.40), 0.76 (1.06), 1.79 (1.51) and 2.23 (1.65). The mean global score was 1.52 (1.25). The regular occurrence of objective and subjective overeating episodes was reported by 10.6% and 12.7% of participants, respectively. The regular use of self-induced vomiting, laxative misuse, and use of diuretics, was reported by 1.4%, 1.0%, and 0.3%, of participants, respectively, while 2.2% of participants reported regularly using diet pills. "Extreme dietary restraint" and "excessive exercise" were reported by 3.4% and 4.9% of participants, respectively. Both attitudinal and behavioural features of eating disorder psychopathology tended to decrease with increasing age. These data will inform researchers intending to use the EDE-Q in epidemiological studies.     

Structure of the Objectified Body Consciousness Scale: Reevaluated 20 Years later

The Objectified Body Consciousness Scale (OBCS) is a prominent measure of key constructs in the body image literature. Despite the impact and popularity of the OBCS, however, investigations of its factor structure have been limited. To our knowledge, the present study is the first since the instrument’s development 20 years ago to provide a detailed evaluation of the replicability of the factor structure of OBCS data in a sample of U.S. college women, the population for which the measure was originally developed and is used most frequently. Specifically, we used confirmatory factor analyses to evaluate the structure of OBCS data and identify areas for measure refinement. Internal consistency reliability and convergent validity were also examined. A sample of 368 U.S. college women completed the OBCS along with measures of body esteem and thin-ideal internalization as convergent validity indicators. Findings revealed that OBCS Control Beliefs items were poor indicators of the factor. A two-factor structure composed of Body Surveillance and Body Shame was supported. Support for internal consistency reliability and convergent validity was also garnered. Additionally, abbreviated versions of the Body Surveillance and Body Shame subscales produced good model-data fit without sacrificing reliability or validity. These results support the use of the OBCS Body Surveillance and Body Shame subscales to assess critical aspects of body image in research and practice contexts; the abbreviated versions of these subscales can address demands for brevity in these contexts.     

Distress Tolerance Scale: A Confirmatory Factor Analysis Among Daily Cigarette Smokers

The present investigation evaluated the factor structure of the Distress Tolerance Scale (DTS; Simons and Gaher 2005) among a sample of 173 (54.9% males) daily cigarette smokers (M = 16.64 cigarettes per day, SD = 7.83). Comparison of a single higher-order model and a hierarchical multidimensional model was conducted using confirmatory factor analyses (CFA). In addition, evaluation of the internal consistency and convergent and discriminant validity of the better-fitting model was completed. CFA of the DTS indicated a single second-order factor of distress tolerance, and four lower-order factors including Tolerance, Appraisal, Absorption, and Regulation; each factor demonstrated acceptable levels of internal consistency. In addition, the DTS displayed good convergent and discriminant validity with theoretically relevant smoking and affect variables. Results are discussed in terms of explicating the latent structure of distress tolerance, as measured by the DTS, within the context of smoking research.     

An Evaluation of the Psychometric Properties of the Womanist Identity Attitudes Scale

Responses from 101 African American/Black and 100 White women were used to examine the psychometric properties of the Womanist Identity Attitudes Scale (WIAS; Ossana, 1986; Ossana, Helms, & Leonard, 1992). First, internal consistency reliabilities suggested the need for further development of 3 of the 4 WIAS subscales. Second, links between WIAS scores and (a) sexist, (b) hostile sexist attitudes toward women, (c) benevolently sexist attitudes toward women, and (d) egalitarian attitudes toward women's rights and roles provided mixed support for the convergent validity of the WIAS. Third, consistent with theoretical conceptualization, the intercorrelations among WIAS subscales were similar for African American/Black and White women. These intercorrelations, however, were not entirely consistent with the theorized developmental process of the womanist identity model. Finally, the structural validity of the WIAS was examined using confirmatory and exploratory factor-analytic procedures. Both sets of analyses challenged the fit of the theorized womanist identity development model with data produced by the WIAS.     

Measuring dysmorphic concern in Italy: psychometric properties of the Italian Body Image Concern Inventory (I-BICI)

The present research evaluated an Italian version of the Body Image Concern Inventory (I-BICI). A total of 412 Italian volunteers from Central and Southern Italy completed the measure (M=27.05 years, range=13-66 years) and the basic psychometric properties (factor structure, internal consistency, convergent validity) were assessed. The total measure demonstrated good internal consistency. Significant correlations were found between the I-BICI and measures of eating disorder (EDI-2) and obsessive-compulsive symptomatology (PI). Confirmatory factor analysis replicated the mesaure’s proposed factor structure. Directions for future research are discussed.     

Spanish adaptation of the Perceived Acceptance Scale (PAS) in university students

The main objective of the present study was to adapt the Perceived Acceptance Scale (PAS), developed by Brock, Sarason, Sanghvi and Gurung to evaluate the cognitive component of perceived social support, to the Spanish language. In a sample of 855 university students registered for the first time in different degree courses, the reliability, dimensionality and external validity of the scale scores were analyzed. The results show adequate internal consistency in both the subscales (friends, family, father and mother) and in the overall scale. The factorial structure, derived from a confirmatory factorial analysis, fitted the theoretical model proposed by the authors of the scale. The scale scores showed evidence of convergent and discriminant validity from the observed relationships with the measures of perceived social support. The psychometric properties of the adapted scale provide an adequate measuring instrument for evaluating perceived acceptance in Spanish university students.     

The internal consistency and concurrent validity of a Spanish translation of the Child Behavior Checklist

The Child Behavior Checklist's applicability to a Hispanic sample was assessed by an examination of the instrument's internal consistency and concurrent validity. The CBCL and TRF were administered to a community sample representative of children of Puerto Rico aged 4 to 16. Cronbach's alpha was used to assess the internal consistency of empirically derived scales. The relation of CBCL and TRF scores to clinical diagnosis, adaptive functioning, and need for services served as indicators of the concurrent validity of the instrument's Spanish version. The results indicate that the total behavior problem scores on the instruments are good continuous measures of maladjustment for children in Puerto Rico. A child with high values on the scales has a high probability of being classified as a case by a psychiatrist. High levels of internal consistency were found in most subscales. Only scales comprising low prevalence problems showed poor internal consistency.
