Comparison of factor structure models for the Beck Depression Inventory--II.

Factor analyses of the Beck Depression Inventory--II (A. T. Beck, R. A. Steer, & G. K. Brown, 1996) have frequently produced 2 different 2-factor oblique structures. The author used confirmatory factor analyses to compare these structures with a general-factor model with 2 orthogonal group factors. The general-factor model fit as well as or better than the 2-factor models when applied to item data from previous studies (3 clinical and 2 college samples). Communalities associated with the General Depression factor ranged from 71% to 82%. Cognitive and Somatic group factors were indicative of intropunitiveness and fatigue. It was concluded that the general-factor model gives an acceptable empirical explanation of item covariance structure and offers a conceptual interpretation that is well suited to clinical practice and research.

The development of the Japanese version of the Maslach Burnout Inventory and the examination of the factor structure

This article presents an evaluation of the factor structures of the Japanese version of the Maslach Burnout Inventory (MBI). The MBI is a widely used psychometric instrument for measuring 'burnout' developed by Maslach and her co-workers. The MBI consists of four subscales: Emotional Exhaustion, Personal Accomplishment, Depersonalization, and Involvement. The MBI was translated into Japanese along with a back-translation and was administered to a sample of 267 nurses. Various psychometric analyses showed that the Japanese version of the MBI has high reliability for the 22 items scored for the frequency dimension. The factor analysis using principal factoring with an oblique rotation resulted in three factor structures that had different implications from the MBI: Emotional Exhaustion/Depersonalization, Personal Accomplishment, and Physical Exhaustion. The correlationship between the MBI and the General Health Questionnaire (GHQ), measures of depression, showed that burnout was a unique phenomenon.     

Hypothesized simple factor structure for the Alcohol Expectancy Questionnaire: Confirmatory factor analysis.

This study proposed and tested a theoretical factor structure for the Alcohol Expectancy Questionnaire (AEQ; S. A. Brown, M. S. Goldman, A. Inn, & L. R. Anderson [see record 1981-01217-001]). Factors were hypothesized to (a) reflect either positive or negative reinforcement, and (b) target either personal feelings or social contexts, resulting in 4 hypothesized factors (Social Enhancement, Social Coping, Personal Enhancement, Personal Coping). Participants were 180 male and 226 female undergraduates who completed the AEQ and additional self-report measures. Confirmatory factor analysis revealed that the hypothesized model fit the data. Post hoc adjustments further improved the model. Finally, a higher order factor model fit the data best. Factors correlated in hypothesized ways with other measures: (a) Only Personal Coping expectancies correlated with negative affect; (b) self-efficacy to resist drinking for emotional relief correlated highest with Personal Coping; and (c) self-efficacy to resist social pressure to drink correlated highest with Social Enhancement. Correlations with B. C. Leigh and A. W. Stacy's (see record 1993-35856-001) Drinking Expectancy Questionnaire indicated congruent and divergent validity.

Benchmarks: Integrating affective and interpersonal circles with the Big-Five personality factors.

Previous research on the Big Five personality factors has not accounted for trait variables interstitial to the factor poles. To better integrate interstitial variables with the Big Five and to provide a framework for reconciling variant versions of the 5 factors, 636 self- and peer ratings using a set of 394 trait adjectives were analyzed. Pairings of 3 factors (I, II, and IV) showed a markedly large incidence of interstitial variables. These 3 factors, referencing affective and interpersonal traits, formed a 3-dimensional space. Adjective clusters defining both factor-univocal and interstitial benchmark positions in this space were developed. The 3 circles defined by the clusters showed appropriate circumplex characteristics when examined in an independent sample of 205 peer ratings. Two of these circles corresponded to the affective and interpersonal circles defined by personality research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The factor structure of Union Commitment: An application of confirmatory factor analysis.

M. E. Gordon et al. (see record 1980-33572-001) developed a Union Commitment scale and identified four underlying factors. L. Friedman and R. J. Harvey (see record 1986-28952-001), in a reanalysis of the Gordon et al. data, concluded that union commitment was best represented by two factors. Although several investigations have replicated the Gordon et al. factor structure, none of these have used confirmatory factor analysis (CFA). In the present study we used CFA to test the explanatory power of the two a priori factor structures. A sample of 465 blue-collar workers working for a large utility company in the midwestern United States participated in this investigation. The results suggest that, first, a modified version of Gordon et al.'s four-factor solution provides a better representation of the factor structure of union commitment. Second, the use of either the four-factor solution or commitment as a unidimensional construct may be justified, depending on the research focus. Finally, we found that unit weighting of the union commitment items was the most appropriate strategy for generating composites. The implication of these results and suggestions for future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A confirmed factor structure for the Biphasic Alcohol Effects Scale.

This study of the Biphasic Alcohol Effects Scale (BAES) examined the factor structure of subjective stimulant and sedative effects on the ascending and descending limbs of the blood alcohol curve. Eighty men reported their subjective responses after consuming 0.5 or 0.8 grams ethanol/kilogram of body weight. The proposed four-factor model of stimulant and sedative effects on the ascending and descending limbs fit the data significantly better than alternative models. This confirmable structure suggests that the scale assesses discernable alcohol-induced changes in stimulation and sedation that vary with dosage and the limb of the blood alcohol curve. No other measure of alcohol-induced subjective effects has a confirmed factor structure. Stimulant and sedative effects varied with dosage and correlated significantly with ratings of intoxication, suggesting that monitoring these responses may help individuals regulate their drinking.

Anomalous factor structure of the WISC—R for diabetic children.

The factor structure of the Wechsler Intelligence Scale for Children—Revised (WISC—R) was analyzed with 95 diabetic children (aged 8–16 yrs), 97 regionally and demographically matched controls, and an age- and race-matched sample from the WISC—R standardization sample (n?=?1,405). Controls exhibited a 3-factor IQ structure, consistent with the standardization sample. Diabetic Ss exhibited a 4-factor structure, with the Perceptual Organization factor splitting in two. Picture Completion (PC) and Picture Arrangement (PA) formed a visual discrimination factor, and Block Design and Object Assembly created a spatial conceptual factor. Among the diabetic Ss, the PC and PA subtests did not act as traditional measures of nonverbal intelligence, and the performance of diabetic Ss on the visual discrimination factor may reflect mild visual atypicalities.

The Youth Client Satisfaction Questionnaire: development, construct validation, and factor structure

Developed and pilot-tested a measure of satisfaction with mental health services for young clients. One hundred fifty youth from 11 to 17 years of age who had completed services received the measure as a telephone interview. Fourteen of 17 candidate items met criteria for test-retest reliability, part-whole correlation, and correlation with a validation item, and they were retained in the instrument. Total score test-retest reliability and internal consistency were highly satisfactory. Principal components analysis revealed two factors, labeled Relationship With Therapist and Benefits of Therapy. Unexpectedly, satisfaction scores were not related to change in youth self-reported behavior problems. However, convergent validity was indicated by significant relationships with change in parent-reported behavior problems, parent satisfaction, parent ratings of treatment progress, therapist ratings of progress, and Global Assessment of Functioning change scores. These results indicate that the Youth Client Satisfaction Questionnaire is a reliable and valid measure of consumer evaluations of their treatment.     

The psychologies of structure, function, and development.

Reviews E. B. Titchner's 1898 analogy between the anatomical, physiological, and morphogenetic aspects of biological research and the structural, functional, and developmental aspects of psychological research. This analogy is applied to contemporary divisions within psychology. In psychology, structural research tends to be described in the cognitive or mentalist vocabulary, and functional research in the behaviorist vocabulary. However, this correlation is accidental. Structural and functional dimensions of psychological problems and their relation to developmental research are examined. It is concluded that much psychological controversy is caused by concern with different problems, and not by different paradigms for studying the same problems. (45 ref.)

The factor structure and screening utility of the Social Interaction Anxiety Scale.

The widely used Social Interaction Anxiety Scale (SIAS; R. P. Mattick & J. C. Clarke, 1998) possesses favorable psychometric properties, but questions remain concerning its factor structure and item properties. Analyses included 445 people with social anxiety disorder and 1,689 undergraduates. Simple unifactorial models fit poorly, and models that accounted for differences due to item wording (i.e., reverse scoring) provided superior fit. It was further found that clients and undergraduates approached some items differently, and the SIAS may be somewhat overly conservative in selecting analogue participants from an undergraduate sample. Overall, this study provides support for the excellent properties of the SIAS's straightforwardly worded items, although questions remain regarding its reverse-scored items.

The revised Psychopathy Checklist: Reliability and factor structure.

The revised Psychopathy Checklist (PCL) is a 20-item scale scored from interview and file information. Analyses of data from 5 prison samples (N?=?925) and 3 forensic psychiatric samples (N?=?356) indicate that the revised PCL resembles its 22-item predecessor in all important respects. It has excellent psychometric properties, and it measures 2 correlated factors that were cross-validated both within and between samples. Correlations between the original PCL and the revised version approached unity for both the factors and the full scale. We conclude that the revised PCL measures the same construct as the original and that the PCL is a reliable and valid instrument for the assessment of psychopathy in male forensic populations.

Hierarchical factor structure of the Wechsler Intelligence Scale for Children—III.

R. J. Wherry and R. J. Wherry (1969) hierarchical factor solutions were obtained on the Wechsler Intelligence Scale for Children—III intercorrelations reported in the standardization sample ( D. Wechsler, 1991). Two- and 4-factor solutions were obtained for the 6-7, 8-10, 11-13, and 14-16 age levels. Both solutions indicated a strong general intelligence (g) factor at all 4 age levels. At the primary level, factors corresponding to the verbal-numerical-educational and spatial-mechanical practical dimensions from Vernon's (1950) paradigm emerged when a 2-factor solution was used. When a 4-factor solution was used, Perceptual Organization, Perceptual Speed, Verbal Comprehension, and Freedom From Distractibility factors were obtained at the primary level.

The hierarchical factor structure of the Wechsler Preschool and Primary Scale of Intelligence.

Performed a Wherry-Wherry hierarchical factor analysis on the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) subtest intercorrelations reported by D. Wechsler for each of the 6 age groups included in the standardization sample. A hierarchical arrangement of abilities highly congruent with P. E. Vernon's 1950 structure-of-intellect theory was obtained. The obtained arrangement consisted of a strong general intelligence factor defined by positive loadings from all subtests, and 2 subgeneral factors: a verbal-educational factor defined by the verbal subtests and a spatial-perceptual factor defined by the performance subtests. The factor structure remained stable across age groups, thus contradicting the differentiation hypothesis. These findings support the construct validity of the WPPSI as a general intelligence assessor and also provide some support for maintaining separate WPPSI Verbal and Performance IQs.

An empirical investigation of the factor structure of the AUDIT.

This study investigated the Alcohol Use Disorders Identification Test's (AUDIT) factor structure and psychometric properties. The factor structure was derived from a sample of 7,035 men and women primary care patients. A principal components analysis identified 2 factors in the AUDIT data and was supported in a confirmatory factor analysis (CFA). The 2 factors were Dependence/Consequences and Alcohol Consumption. The CFA also provided support for a 3-factor model whose factors (Alcohol Consumption, Alcohol Dependence, and Related Consequences) matched those proposed by the AUDIT'S developers. Psychometric indexes were determined by use of the baseline and 12-month follow-up data of 301 men and women who entered a clinical trial. The results showed that the 2 factors had good reliability. Validity tests supported the interpretation of what the 2 factors measure, its implications for relationships to other variables, and the comparability of the 2- and 3-factor models.

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.

Meta-analysis of the Brief Psychiatric Rating Scale factor structure.

A meta-analysis (N=17,620; k=26) of factor analyses of the Brief Psychiatric Rating Scale (BPRS) was conducted. Analysis of the 12 items from Overall et al.'s (J. E. Overall, L. E. Hollister, & P. Pichot, 1974) 4 subscales found support for his 4 subscales. Analysis of all 18 BPRS items found 4 components similar to those of Overall et al. In a 5-component solution, a 5th activation component emerged but was best supported among samples of schizophrenic patients. The first 4 components appear to form the core of the BPRS factor structure. Results of the meta-analysis suggest 5 subscales (with items in parentheses): Affect (anxiety, guilt, depression, somatic); Positive Symptoms (thought content, conceptual disorganization, hallucinatory behavior, grandiosity); Negative Symptoms (blunted affect, emotional withdrawal, motor retardation); Resistance (hostility, uncooperativeness, suspiciousness); and Activation (excitement, tension, mannerisms-posturing).

A reexamination of the WAIS—R factor structure.

The factor structure of Wechsler's Adult Intelligence Scale—Revised (WAIS—R) has been a subject of controversy since the instrument was first published. We performed a series of restricted factor analyses on the 9 cohorts of the WAIS—R standardization sample in an effort to investigate the structure of this instrument. Several indices of fit were used including (a) the likelihood ratio test statistic, chi-square; (b) the LISREL Goodness of Fit Index; (c) the normed-fit index, with both a null and informed baseline; (d) the rescaled Akaike and Schwartz criteria; and (e) the root mean square residual. Results indicated that a 3-factor model accounts best for the relations among the 11 WAIS—R subtests in 8 of the 9 standardization cohorts. The 3 factors correspond to the Verbal Comprehension, Perceptual Organization, and Memory/Freedom From Distractibility factors that have been identified in the WAIS. Factor comparison procedures were used to test the generalizability of this structure in psychiatric and medical samples. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
