The Circumplexity of Leary's Interpersonal Circle: A Multidimensional Scaling Perspective

To investigate the circulant structure of the 16 scales comprising the Interpersonal Checklist (ICL; Laforge & Suczek, 1955), intercorrelation matrices for mate and female undergraduate ICL scores were subjected to multidimentional scaling analysis. Results showed the following: (a) while the 16 ICL scales fall in a rough circular array, measurement gaps exist in the friendly-dominant and hostile-submissive quadrants; (b) sixteenths A-B-P and L-M-N were misarranged; (c) stress coefficients for a three-dimensional solution were in an acceptable range. Implications of these findings for future research and anchoring of the ICL to Kiesler's (1983) "1982 Interpersonal Circle" are discussed.     

The Natural History of an Outcome Prediction

This study investigated the relationship between accuracy in figure drawing interpretation and interpersonal style. Subjects were 66 undergraduates who completed the Minnesota Multiphasic Personality Inventory (MMPI), the Interpersonal Check List (ICL), and a figure drawing interpretation task. The MMPI and ICL were scored and interpreted using Leary's Interpersonal System, which provides for a multilevel assessment of interpersonal functioning. Interpretive skill was found to be associated with "affiliative" interpersonal styles (p < .05), and lack of interpretive skill was associated with "disaffiliative" interpersonal styles (p < .05) at two of the three levels examined. The role of unconscious processes in figure drawing interpretation, the nature of the interpretive process, and implications for the selection of skilled interpreters are discussed with reference to the interpersonal characteristics of the interpreter.

Interpersonal personality measures show circumplex structure based on new psychometric criteria

The importance of the interpersonal circle in organizing the interpersonal domain is complemented by its empirical relations with broader personality taxonomies and with more specific personality variables. Yet circumplex structure in interpersonal measures has often been investigated using the "eyeball test" rather than using circumplex criteria of known effectiveness. Simulations (Acton, 1999) showed the effectiveness of 5 exploratory criteria (3 entirely new) that assess the properties of equal spacing, constant radius, and no preferred rotation. Along with Browne's (1992) criterion, these were applied to the Interpersonal Checklist (ICL; LaForge & Suczek, 1955; N = 763), Interpersonal Adjective Scales (IAS; Wiggins, 1979; Ns = 716 and 187), Revised IAS (IAS-R; Wiggins, Trapnell, & Phillips, 1988; N = 474), Inventory of Interpersonal Problems Circumplex Scales (IIP-C; Alden, Wiggins, & Pincus, 1990; Ns = 616 and 1,381), and Inventory of Interpersonal Goals (IIG; Horowitz, Dryer, & Krasnoperova, 1997; N = 318). In corroboration of interpersonal theory, all showed circumplex structure.     

The Radex Structure Of The Leary Interpersonal Behavior Circle

Two experiments were run in which the structure of the Interpersonal Check List (ICL) was studied. Both studies demonstrated that the ICL comprised a circular ordering of traits at several levels of intensity. This structure, defined by Guttman as a radex, incorporates the social desirability of trait ratings in a simple model.

In corroboration of interpersonal theory, all showed circumplex structure.     

A comprehensive and indexed bibliography of the interpersonal check list

The LaForge-Suczek Interpersonal Check List has been widely used in psychological and social-psychological research, in the evaluation of psychotherapy outcome, and as a component of psychological assessment batteries. Although there is a substantial body of literature on the ICL, access to this literature has been quite limited. In working on the present bibliography, it was found that Psychological Abstracts and computer searches failed to yield sufficient coverage of the ICL literature. It is hoped that this comprehensive, indexed bibliography will make it easier for the interested reader to gain an understanding of the development, application and usefulness of the ICL.     

The circle as a model for the interpersonal domain of Swedish trait terms

Swedish interpersonal traits were assumed to have the structure demonstrated by Wiggins for the Interpersonal Adjective Scales in English. Positive and negative interpersonal trait terms were rated for accuracy when describing people. The ratings were used to construct 16 eight-item scales which were ordered relative to two principal components and labelled A to P. The evaluative meaning of each scale item was rated by a second group. The ranks of the mean ratings for the scales followed expectations. The 16 scales were combined into eight scales PA, BC, DE, etc., to NO. From a new group of subjects (N = 159) self-ratings were obtained. The correlations between the eight scales were used to obtain maximum-likelihood estimates of population coefficients of a hypothetical circulant matrix. A circumplex model fitted the data well and the two equally large orthogonal components ordered the PA to NO variables within a circular semantic space. The model was interpreted as a structural representation of basic-level categories for interpersonal attributes of personality in the natural language.     

The Experiences in Close Relationship Scale (ECR)-Short Form: Reliability,Validity, and Factor Structure

Convergence between the MMPI–2 Restructured Form (MMPI–2–RF; Ben-Porath &; Tellegen, 2008) interpersonal scales and 2 interpersonal circumplex (IPC) measures was examined. University students (N = 405) completed the MMPI–2 and 2 IPC measures, the Interpersonal Adjectives Scales Revised Big Five Version (IASR–B5; Trapnell &; Wiggins, 1990) and the Inventory of Interpersonal Problems Circumplex (IIP–C; Horowitz, Alden, Wiggins, &; Pincus, 2000). Internal consistency was adequate for 3 of the 6 scales investigated. The majority of scales were located in their hypothesized locations, although magnitude of correlations was somewhat weaker than anticipated, partly owing to restricted range from using a healthy sample. The expected pattern of correlations that defines a circular matrix was demonstrated, lending support for the convergent and discriminant validity of the MMPI–2–RF interpersonal scales with respect to the assessment of interpersonal traits and problems.     

Construction of Circumplex Scales for the Inventory of Interpersonal Problems

We constructed a set of circumplex scales for the Inventory of Interpersonal Problems (IIP; Horowitz, Rosenberg, Baer, Ureno, & Villasenor, 1988). Initial scale construction used all 127 items from this instrument in two samples of university undergraduates (n = 197; n = 273). Cross-sample stability of item locations plotted against the first two principal components was high. A final set of eight 8-item circumplex scales was derived from the combined sample (n = 470) and cross-validated in a third university sample (n = 974). Finally, we examined the structural convergence of the IIP circumplex scales with an established measure of interpersonal dispositions, the Revised Interpersonal Adjective Scales (IAS-R; Wiggins, Trapnell, & Phillips, 1988). Although both circumplex instruments were derived independently, they shared a common Circular space. Implications of these results are discussed with reference to current research methods for the study of interpersonal behavior.     

A Further Study of the Validity of Human Form Drawings In Personality Evaluation

Three studies describe the development, psychometric properties, and potential utility of a new self-report measure, the Circumplex Scales of Interpersonal Values (CSIV). The CSIV was designed to complement other interpersonal circumplex measures that assess interpersonal behavior by efficiently assessing a comprehensive set of agentic and communal values. The eight 8-item scales of the CSIV were shown to have good internal consistency and test-retest reliability and a circumplex structure. The CSIV showed convergent and discriminant validity with measures of interpersonal traits (the Bem Sex Role Inventory; Bem, 1974), interpersonal problems (the Inventory of Interpersonal Problems-Circumplex; Horowitz, 2000), implicit interpersonal motives (the Thematic Apperception Test; see Atkinson, 1958), and interpersonal goals (the Interpersonal Goals Inventory; Dryer &; Horowitz, 1997). Finally, the locations of the MCMI-III (Millon, 1994) personality disorder scales on the CSIV circumplex generally mirrored the locations of personality disorders on other interpersonal circumplex measures.     

Circumplex scales of interpersonal values: reliability, validity, and applicability to interpersonal problems and personality disorders

The CSIV was designed to complement other interpersonal circumplex measures that assess interpersonal behavior by efficiently assessing a comprehensive set of agentic and communal values. The eight 8-item scales of the CSIV were shown to have good internal consistency and test-retest reliability and a circumplex structure. The CSIV showed convergent and discriminant validity with measures of interpersonal traits (the Bem Sex Role Inventory; Bem, 1974), interpersonal problems (the Inventory of Interpersonal Problems-Circumplex; Horowitz, 2000), implicit interpersonal motives (the Thematic Apperception Test; see Atkinson, 1958), and interpersonal goals (the Interpersonal Goals Inventory; Dryer & Horowitz, 1997). Finally, the locations of the MCMI-III (Millon, 1994) personality disorder scales on the CSIV circumplex generally mirrored the locations of personality disorders on other interpersonal circumplex measures.     

Effects of client presenting syndromes on client and therapist dominance and affiliation during early sessions of Rational-Emotive psychotherapy

This is a study of effects of presenting clinical status on interpersonal presentation during early Rational-Emotive therapy (RET). Independent variables were intake scores for clients from the axis I scales of the Millon Clinical Multiaxial Inventory (MCMI; Millon, 1983). Dependent variables, from audiotapes of sessions at the Institute for RET (IRET), were Revised Interpersonal Adjective Scale (IAS-R; Wiggins, Trapnell and Phillips, 1988) ratings of clients and therapists. MCMI scales associated with stimulation seeking (N, hypomania; T, drug abuse) were significantly positively correlated with client dominance. Therapist affiliation was negatively correlated with all client MCMI scales, and these were significant for scales that assessed the most severe intake presenting problems (A, anxiety, D, dysthymia).     

Convergence among measures of interpersonal attraction

The purpose of this research was to determine whether Rubin's (1970) Liking and Love scales, the Interpersonal Jealousy scale of Mathes and Severa (1981), and a measure of sexual attraction, the Sexual Attraction scale, measure the same or independent dimensions of interpersonal attraction when applied to same- and opposite-sex friends rather than dating partner. It was found that the Liking and Love scales appeared to measure the same dimension of interpersonal attraction. However, this dimension was independent of the dimension measured by the Interpersonal Jealousy scale and the dimension measured by the Sexual Attraction scale. The latter two dimensions were also independent of each other.     

Validity of the PAI interpersonal scales for measuring the dimensions of the interpersonal circumplex

Two studies evaluated the validity of the interpersonal scales, Dominance (DOM) and Warmth (WRM), from the Personality Assessment Inventory (PAI; Morey, 1991, 2007) to measure the 2 dimensions of the interpersonal circumplex (IPC). In Study 1, 114 college freshmen completed the PAI and the Interpersonal Adjectives Scale (IAS; Wiggins, 1995). In Study 2, 170 college students completed the PAI and the Inventory of Interpersonal Problems-Short Circumplex (IIP-SC; Soldz, Budman, Demby, & Merry, 1995). The results of both studies supported the convergent validity of DOM and WRM, although discriminant validity was stronger using the IIP-SC as the criterion. Circumplex projections placed DOM and WRM in the appropriate segments of both the IAS and IIP-SC. These findings provide additional support for the validity of the PAI interpersonal scales as measures of the primary dimensions of the IPC.     

Reexamination of the Bem Sex-Role Inventory: The Interpersonal BSRI

The 40 masculine and feminine items of 746 Bern Sex-Role Inventory (BSRI; Bern, 1974) were subjected to a principal axis factor analysis with varimax rotation. Results revealed a four-factor solution, indicating that the original BSRI items do not provide two unidimensional ratings of femininity and masculinity. However, some support is given to Bern's initial two-factor thesis in that two principal factors emerged: one consisting of items that were originally identified as feminine, the other consisting of items that were originally identified as masculine. Content examination of the two principal factors resulted in an interpretation of the factors as Interpersonal Sensitivity and Interpersonal Potency. Internal consistency and validity of these two scales were examined and found to be adequate.     

Interpersonal development, stability, and change in early adulthood

The goal of this research was to explore the development of the interpersonal system mapped by the interpersonal circumplex in early adulthood (ages 18–22). This study uses the Longitudinal Study of Personality Disorders sample (N = 250; 53% female). Participants completed the Revised Interpersonal Adjective Scales (Wiggins, Trapnell, & Phillips, 1988) in their freshman, sophomore, and senior years of college. Estimates of structural, rank‐order, mean, individual, and ipsative stability were calculated for the broad interpersonal dimensions of Dominance and Affiliation and also the lower order octant scales. Additionally, the interpersonal profile parameters of differentiation and prototypicality were calculated at each wave and explored longitudinally and also used as predictors of interpersonal stability. We found excellent structural and high rank‐order and ipsative stability in the interpersonal scales over this time period. Mean increases on the Affiliation axis, but not on the Dominace axis, were found to mask differential rates of change among the octant scales, along with significant individual variation in the rates of change. Interpersonal differentiation and prototypicality were related to higher stability in overall interpersonal style. Results point to evidence of both stability and nuanced change, illuminating some of the features of the structural variables that can be derived from interpersonal circumplex profiles.     

Swedish translations of the Suicide Probability Scale, Perceived Social Support from Friends and Family Scales, and the Scale for Interpersonal Behavior: A reliability analysis

The Suicide Probability Scale (SPS), the Perceived Social Support (PSS) from Friends (PSS-Fr) and Family (PSS-Fa) scales, and the Scale for Interpersonal Behavior (SIB) were translated into Swedish and their reliability was estimated in a university student sample. The reliability coefficients indicated that both subscales and the total scales of the SPS, PSS, and SIB possess highly adequate reliabilities. The intercorrelations among the subscales and between the subscales and the total scales were found to be highly significant. The results of the study supported the use of SPS, PSS-Fr and PSS-Fa, and the SIB as reliable methods for assessing suicide risk, perceived social support from friends and family, and assertive behavior.
