Stanford-Binet Iv Intelligence Scale: Is Its Structure Supported By Lisrel Congeneric Factor Analyses?, Gregory J. Boyle Jan 1990

Stanford-Binet Iv Intelligence Scale: Is Its Structure Supported By Lisrel Congeneric Factor Analyses?, Gregory J. Boyle

Gregory J. Boyle

Boyle (Personality and Individual Differences, 10, 709-715, 1989b) conducted an iterative principal factoring and oblique rotation of the standardisation sample (n = 5,013) for the revised Stanford-Binet Intelligence Scale (Fourth Edition). Nevertheless, because of the exploratory methodology employed, the results were problematic. Keith, Cool, Novak, White and Pottebaum (1988)-(Journal of School Psychology, 26, 253-274) had previously carried out a confirmatory factor analysis and had concluded that the results supported the four Area dimensions (Verbal Reasoning, Quantitative Reasoning, Abstract/Visual Reasoning, and Short-Term Memory) in the new instrument. As congeneric factor analysis via LISREL has not yet been performed, the present paper …

Confirmation Of The Structural Dimensionality Of The Stanford-Binet Intelligence Scale (Fourth Edition), Gregory J. Boyle Jan 1989

Confirmation Of The Structural Dimensionality Of The Stanford-Binet Intelligence Scale (Fourth Edition), Gregory J. Boyle

Gregory J. Boyle

The new Stanford-Binet Intelligence Scale (fourth edition) seemingly represents an important advance in design and construction over the earlier form L-M. The latest version of the instrument (SB-IV) is purported to index both crystallized intelligence (Verbal and Quantitative Reasoning Areas) and fluid intelligence (Abstract/Visual Reasoning Area) structural dimensions respectively. Given the prominence of modem information­ processing theories of cognition, a separate Short-Term Memory (STM) Area is also provided. The authors provided confirmatory factor analytic (CFA) evidence to support their claim for the construct validity of each of the four cognitive ability areas. However, several inconsistent factor loadings were apparent, for …


Factor Structure Of The Differential Emotions Scale And The Eight State Questionnaire Revisited, Gregory J. Boyle Jan 1989

Factor Structure Of The Differential Emotions Scale And The Eight State Questionnaire Revisited, Gregory J. Boyle

Gregory J. Boyle

The Differential Emotions Scale (DES-IV) and the Eight State Questionnaire (SSQ) are two separately developed multidimensional instruments purported to index simultaneously a number of fundamental emotional/mood states. The two instruments combined quantify some 20 primary mood states, which, in practice, may provide too complex a picture to be of benefit in many applied and research settings. Attempts to derive higher-order mood-state factors from both the DES-IV and the SSQ have yielded somewhat inconsistent results. In. this paper an attempt was made to resolve this issue by reanalysing data collected from 450 Australian tertiary college students. The results indicated that there …


Anomaly In Equation For Calculating 16pf Second Order Factor Qiii, Gregory J. Boyle Jan 1989

Anomaly In Equation For Calculating 16pf Second Order Factor Qiii, Gregory J. Boyle

Gregory J. Boyle

Recently, the Institute for Personality and Ability Testing (IPAT) has released a new set of equations for calculating 16PF second-order factors. These revised equations were compared with the earlier ones provided in the l6PF Handbook, as well as with those used in the Clinical Analysis Questionnaire (CAQ) for computing the second-order trait dimensions. It was found that the earlier 16PF Handbook equation for calculating QIII (Tough Poise) was not accurate. It is recommended that only the new equations be employed in future work with the 16PF. Moreover, this finding may have implications for published studies involving the 16PF second-order factors …


Sex Differences In Reported Mood States, Gregory J. Boyle Jan 1989

Sex Differences In Reported Mood States, Gregory J. Boyle

Gregory J. Boyle

It is generally agreed that females tend to assent more readily to negative mood states such as Anxiety or Depression, than do males. The present study explored this issue on a large sample of male and female Education undergraduate students, using the Eight State Questionnaire (8SQ) as the measure of mood states. Several studies had previously suggested that the 8SQ is a useful multidimensional instrument for quantifying a wide range of clinically important mood states. Results indicated that male and female students responded differentially to a minority of the 8SQ items, and that the factor structure of reported moods differed …


Dimensions Of Adolescent Motivation As Measured By Higher-Order Factors In The School Motivation Analysis Test, Gregory J. Boyle, K Brian Start, E John Hall Jan 1989

Dimensions Of Adolescent Motivation As Measured By Higher-Order Factors In The School Motivation Analysis Test, Gregory J. Boyle, K Brian Start, E John Hall

Gregory J. Boyle

Although previous analyses of higher-order motivational dimensions have suggested at least seven major dynamic traits among adults, corresponding analyses among adolescents have not yet been undertaken in any satisfactory manner. To this end, the present article reports the results of a higher-order factor analysis of the subscale intercorrelations for the School Motivation Analysis Test (SMAT) on an Australian sample of 277 Year I 0 students enrolled in various senior high schools. The results suggest that at least six factors maximally account for the common variance in the SMAT. Tentative interpretations of the higher-order factors obtained are made and discussed in …


Contribution Of Cattellian Psychometrics To The Elucidation Of Human Intellectual Structure, Gregory J. Boyle Jan 1988

Contribution Of Cattellian Psychometrics To The Elucidation Of Human Intellectual Structure, Gregory J. Boyle

Gregory J. Boyle

The development of a taxonomy of human intellectual structure has received much impetus during the last decade. Findings indicate that there are at least 30-40 primary abilities, rather than only the seven proposed by Thurstone. While this list does not constitute a definitive taxonomy of primary ability structures, nevertheless, much of the ability variance should be accounted for by the presently known factors. At the second stratum level, several major factors (Gf, Gc, Gm, Gps, Gr, Gv, Ga) have been well replicated in numerous studies. Evidence indicates a smaller number of primary ability factors in children and old-aged individuals: Several …


Central Clinical States: An Examination Of The Profile Of Mood States And The Eight State Questionnaire, Gregory J. Boyle Jan 1988

Central Clinical States: An Examination Of The Profile Of Mood States And The Eight State Questionnaire, Gregory J. Boyle

Gregory J. Boyle

Two multidimensional mood-state inventories, the Profile of Mood States (POMS) and the Eight State Questionnaire (8SQJ, were administered to 289 Australian college undergraduates. lntercorrelations for the combined 14 subscales were subjected to a higher-order factor analysis in order to elucidate the central clinical states within the mood-state sphere. Results suggested four major state dimensions pertaining to Neuroticism, Hostility/Anger, Vigor, and a combined Extraversion/Arousal-Fatigue entity. Both three- and jive­ factor solutions were taken out for comparative purposes. Furthermore, separate higher-order factorings of the POMS on normative samples of 350 male and 650 female psychiatric outpatients were conducted, corroborating three of the …


A First Delineation Of Higher Order Factors In The Children's Motivation Analysis Test (Cmat), Gregory J. Boyle Jan 1988

A First Delineation Of Higher Order Factors In The Children's Motivation Analysis Test (Cmat), Gregory J. Boyle

Gregory J. Boyle

The Children's Motivation Analysis Test (CMAT) is an objective pencil-and paper instrument designed to measure 10 of the most important motivational dynamic traits among young children. The instrument (which is a downward extension of the School Motivation Analysis Test – SMAT – for use with adolescents), is not only a new addition to the field of motivation measurement, but it is also a major breakthrough for assessing children's motivational structure without the difficulties associated with self-report questionnaires. The present paper reports the results from a higher-order factoring of the CMAT, thereby enhancing the usefulness of the instrument, by enabling both …

Quantitative And Qualitative Intersections Between The Eight State Questionnaire And The Profile Of Mood States, Gregory J. Boyle Jan 1987

Quantitative And Qualitative Intersections Between The Eight State Questionnaire And The Profile Of Mood States, Gregory J. Boyle

Gregory J. Boyle

Canonical-redundancy analyses were computed across the Profile of Mood States (POMS) and the Eight State Questionnaire (8SQ) on a sample of 289 university undergraduates in order to estimate the degree of measurement overlap of the two multidimensional mood­state instruments. Additionally, content similarities and differences across subscales were investigated via. a stepwise forward multiple regression approach. Results indicated some measurement commonality across instruments, but also demonstrated that the POMS and 8SQ tap considerable discrete mood-state variance. These findings add to a gradually emerging picture of the inter-relationships among emotional states.


Typological Mood-State Factors Measured In The Eight State Questionnaire, Gregory J. Boyle Jan 1987

Typological Mood-State Factors Measured In The Eight State Questionnaire, Gregory J. Boyle

Gregory J. Boyle

Previous studies of the higher-order state-change factors in the Eight State Questionnaire (8SQ) have suggested that at least three typological mood-state dimensions are measured in the instrument. Nevertheless, the appropriate dR-factor analytic methodology has not always been employed, and even when it has (e.g. Boyle, 198Sa), the sample size has been sufficient to allow only preliminary conclusions. The present study explores more thoroughly this issue of typological mood-state factors in the 8SQ using a large sample of 470 subjects. A dR-factoring of the intercorrelations for the subscale difference scores (across two separate measurement occasions) clearly suggests the presence of four …


Secondary Mood Type Factors In The Differential Emotions Scale (Des Iv), Gregory J. Boyle Jan 1987

Secondary Mood Type Factors In The Differential Emotions Scale (Des Iv), Gregory J. Boyle

Gregory J. Boyle

The DES-IV (a 49-item version of the Differential Emotions Scale) was administered to 212 undergraduate college students on two separate measurement occasions. The resulting subscale scores were intercorrelated and subjected to an iterative principal factoring procedure together with rotation to direct Oblimin simple structure, for each measurement occasion separately. Three emotional mood-type factors accounted for much of the variance in the DES-IV subscales, suggesting the feasibility of scoring the instrument for typological factors. Comparisons with previous higher-order factorings of the instrument are made and results are discussed in terms of obtained coefficients of concordance across measurement occasions.


Use Of Change Scores In Redundancy Analyses Of Multivariate Psychological Inventories, Gregory J. Boyle Jan 1987

Use Of Change Scores In Redundancy Analyses Of Multivariate Psychological Inventories, Gregory J. Boyle

Gregory J. Boyle

Both canonical and multiple-regression redundancy analyses were computed on the 20 separate subscale change-scores for the Eight State Questionnaire (8SQ) and the Differential Emotions Scale (DES-IV), using a sample of 212 undergraduate students. In comparing the measurement overlap of the two measures, it was important, since state-change dimensions were of interest, that across­ occasions difference scores be used rather than single-occasion absolute scores. Viability of this approach was demonstrated and only minor redundancy was evident for the 8SQ and DES-IV instruments. On the present evidence, it appears that both inventories are tapping essentially discrete psychological variance (allowing for trait contamination) …


Evidence Of Typological Mood States From Change-Score (Dr)-Factoring Of The Clinical Analysis Questionnaire, Gregory J. Boyle Jan 1987

Evidence Of Typological Mood States From Change-Score (Dr)-Factoring Of The Clinical Analysis Questionnaire, Gregory J. Boyle

Gregory J. Boyle

A series of studies has attempted to elucidate higher-order mood-state dimensions through factor analyses of a number of multidimensional self-report instruments. Results suggest at least five higher-order mood states (Extraversion, Neuroticism, Arousal-Fatigue, Hostility, Depression). However, the question of possible mood states in the psychopathological domain remains unresolved. The present study investigates this issue through second- and third-order dR-analyses of the Clinical Analysis Questionnaire (CAQ). Results indicate further abnormal typological mood-state factors in addition to those previously delineated within the (normal) mood-state sphere.
