Distinctive career orientations of Holland personality types

The primary source of empirical support for Holland's (1973) assumption that people tend to prefer and search for environments that are consistent with their dominant personal characteristics has been research on the tendency of college students to choose congenial college environments. The purpose of this study is to determine if a sample of male college students, classified according to Holland's six personality types, also prefer occupational environments that are consistent with their primary personal orientations. Stepwise, discriminant analysis procedures are used to test the null hypothesis that there are no statistically significant differences in the characteristics of occupational environments preferred by male students classified according to Holland's personality types. The relationship of the results of this analysis to possible improvements in the areas of career counseling and placement services and future research on job satisfaction in complex organizations is discussed.     

Career change and congruence of personality type: An examination of DOT-derived work environment designations

Holland's theory of congruence of work environments was examined by analyzing the career redirection of 62 men of managerial and professional level who changed occupations between the ages of 33 and 54. Three-letter personality codes for each subject were obtained by administering the Strong-Campbell Interest Inventory. Dictionary of Occupational Titles codes for first and second occupation were obtained and then translated into Holland codes. These were compared to the personality code for each man to determine whether the first or second job was more congruent. It was found that 26 men changed to careers more congruent with their personality, 25 to careers less congruent, and 11 made no change. The results of the study do not lend support to Holland's theory, probably because of the imprecision of DOT categories for research purposes. The need for a more reliable means for coding work environments is discussed.     

Beyond the high point code in testing Holland's theory

This study was designed to test and expand Holland's vocational development theory by utilizing more than a single high point code in classification of personality patterns of jobs. Significant positive results were obtained to support Holland's premise that people search out environments and, hence, vocations that are compatible with their personalities. A more “refined” and/or “subtle” difference was shown in the personality-job relationships when two high point codes were used.     

Personality correlates of Holland's occupational types: A cross cultural study

Recent studies have investigated the personality traits of persons in Holland's six occupational categories. In the present study the generalizability of Holland's characterizations of adults within the occupational categories was investigated in a group of 402 Mexican-Americans. Occupational Scale scores on the Kuder Occupational Interest Survey were used to classify subjects into Holland's occupational types. Multiple discriminant analysis of groups' Guilford-Zimmerman Temperament Survey scale scores resulted in significant overall groups differentiation and two significant discriminant functions for males but no significant results for females. The personality characteristics of the male groups provide strong support for the generalizability of Holland's characterizations to Mexican-American males.     

A six orthogonal factor model of adolescent personality derived from the HSPQ

Attention is drawn to recent major critiques of Cattell's ‘16 PF’ model of personality. Various six/seven-factor models of personality (assuming intelligence is included) derived from the 16 PF or its precursors are described. The equation of Eysenck's E and N factors with Cattell's second-order factors of ‘exvia’ and ‘anxiety’ is mentioned. An examination is made of the problems of factored scale construction and the ‘number of factors’ issue, especially when item responses are analysed.Three previous second-order factor solutions to the HSPQ are presented. These show a remarkable degree of concordance among themselves and with an item analysis of the HSPQ conducted by the writers. This item analysis also reveals serious doubts about the primary trait structure proposed by Cattell and Cattell (1969). It is suggested that, for adolescents, the four studies, with some support from the 16 PF analyses, point to a six-factor structure for personality consisting of anxiety ( = Eysenck's N); tender-tough-mindedness ( = Eysenck's Psychoticism); carefulness-casualness and two aspects of extraversion-introversion: (a) preference for working with people rather than with things. (b) Classical extraversion (the last or both (a) and (b) being analogous to Eysenck's E) and finally intelligence, if this can be classified as an aspect of personality.     

Prototypicality and personality: Effects on free recall and personality impressions

An experiment was performed to test the hypothesis that it is easier to process information about characters who fit well with and are, therefore, “prototypical” of shared beliefs about various personality types. Character prototypicality was manipulated in a free recall and personality impression paradigm through variations in the consistency of a character's identification with preexisting beliefs about two personality-type categories—extraversion and introversion. Subjects also were given information about each character that varied in degree of abstraction from traits to concrete behavior. As predicted, both the amount and nature of the information correctly recalled were significantly affected by the consistency of the character's identification with extraversion or with introversion. Character consistency also significantly affected the amount of material written in the personality impressions and the tendency to qualify the generality of the impressions. The results support a model in which incoming data about personality are coded, structured, elaborated, and remembered according to the quality of their match with preexisting beliefs about various personality types.     

Students' perceptions of personality needs and environmental press as a function of program separation

A sample of 1,877 high school seniors completed the Activities Index and High School Characteristics Index. The student responses were used to identify personality needs and environmental press differences across program and degree of program separation variables.It was concluded that: (1) College preparatory students perceived high personality needs for intellectual endeavors, while vocational students had needs for the tangible and concrete. (2) The personality differences across degrees of program separation suggested the physical proximity of the two program groups affected students' interpersonal relationships. (3) Several of the environmental press were exactly opposite the students' perceived personality needs. (4) The nonsignificant needs-press relationships suggested that high school environments were not facilitating the personality needs of students. (5) Comprehensive high schools seemed the most viable administrative configuration for servicing the diverse needs of today's high school students.     

A theory of careers encounters sex: Reply to Holland (1976)

This paper is the third in a series beginning with a report (by the authors) of research on the application of Holland's theory of careers to women and men. Holland's response, “The Virtues of the SDS …” is considered, in particular, research he cites on the effect of the Self-Directed Search (SDS) on counselees and his advocacy of raw score reports of personality patterns. The widely divergent career options suggested to men and women by SDS raw scores are noted and misunderstandings concerning the implications of Holland's assessment procedures for his theory are discussed. Holland's defense of raw score reports of personality characteristics is found wanting, especially in light of the support provided for his theory by normed scores.     

Concurrent validity of Holland's theory for non-college-degreed working women

This study, using the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS), explored the concurrent validity of Holland's theory for employed non-college-degreed women. The VPI and SDS were administered to 114 women workers in occupational environments consistent with Holland's vocational environments. The results revealed that three scales of the VPI and five scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical notions. In general, the findings lend some support to the concurrent validity of Holland's theory for employed non-college-degreed women.     

Concurrent validity of Holland's theory for non-college-degreed black women

This study, using the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS), explored the concurrent validity of Holland's theory for employed non-college-degreed black women. The VPI and the SDS were administered to 102 black women workers in occupational environments consistent with Holland's six vocational environments. The results revealed that four scales of the VPI and four scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical notions. In general, the findings lend some support to the concurrent validity of Holland's theory for employed non-college-degreed black women.     

Concurrent validity of Holland's theory for college-degreed black women

This study, using the Vocational Preference Inventory (VPI) and the Self Directed Search (SDS), explored the concurrent validity of Holland's theory for employed college-degreed black women. The VPI and SDS were administered to 93 black women workers in occupational environments consistent with Holland's six vocational environments. The results revealed that four scales of the VPI and five scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical notions. In general, the findings lend some support to the concurrent validity of Holland's theory for employed college-degreed black women.     

Sex and cultural differences in the factorial structure of the self-directed search

Holland's Self-Directed Search was administered to 247 male and 252 female high school students, aged 16 to 18 years, attending state schools in New Zealand. Principal factor analysis was used in an attempt to identify six orthogonal factors analogous to Holland's six personality types. The Social and Enterprising scales could not be split into two factors in either sample, and the Investigative and Realistic scales defined a single factor for the female students. Computed distances between pairs of the six personality types in five dimensional factorial space were compared with the relative ordering of the distances expected from Holland's hexagonal model. The positions of the types in space corresponded more closely with the model for the males than they did for the females. The results, in conjunction with those of similar studies in Israel and the United States, imply that the correspondence between some summary codes on the SDS and existing occupational classifications based on Holland's types may be less than perfect, particularly for females. Also, care should be taken when using codes on the SDS to calculate Holland's indices of “consistency,” especially for females.     

Concurrent validity of Holland's theory for college degreed working women

The study was designed to explore two areas: (1) the concurrent validity of Holland's theory for employed college degreed women using two different operational definitions (Vocational Preference Inventory and the Self-Directed Search) of vocational orientation; and (2) the relationships among same named scales across the VPI and the SDS. Concurrent validity was studied by administering the VPI and the SDS to 179 women workers in occupational environments consistent with Holland's six vocational environments. In general, the findings indicate that the VPI and SDS scales tend to effectively discriminate among the occupational groups consistent with Holland's theoretical framework. In addition, the correlation coefficients for same named scales for the two inventories were all found to be significant. In sum, the results of the study lend some support to the concurrent validity of Holland's theory for employed college degreed women.     

Concurrent validity and Holland's theory

This study was designed to explore two areas: (1) the concurrent validity of Holland's theory for employed men using four different operational definitions of vocational orientation, and (2) the relationships among all possible combinations of same named scales across the four inventories. Concurrent validity was studied by administering the Vocational Preference Inventory, the Self Directed Search, and the Holland Scales (Set I and Set II) to 153 male workers established in occupational environments consistent with Holland's six vocational environments. The results revealed that five scales of the VPI and of the Holland Scales (Set I and Set II) and four scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical framework. The correlation coefficients for same named scales for all possible combinations of the four inventories were all found to be significant. In general, the findings of this study tend to support the concurrent validity of Holland's theory for employed men.     

Causal attributions for behaviors consistent or inconsistent with an actor's personality traits: Differences between those offered by actors and observers

The present research was designed to investigate differences in the attributions offered from the actor's perspective and the observer's perspective. It was predicted that causal attributions for behaviors inconsistent with an actor's personality traits would be more situational when offered from the actor's perspective than when offered from the observer's perspective. In contrast, it was predicted that causal attributions for behaviors consistent with an actor's personality traits would be more dispositional when offered from the actor's perspective than when offered from the observer's perspective. Consistent with these hypotheses, extraverts explained introverted behaviors and introverts explained extraverted behaviors more situationally from the actor's perspective than from the observer's perspective. Furthermore, extraverts explained extraverted behaviors and introverts explained introverted behaviors more dispositionally from the actor's perspective than from the observer's perspective. These differences in the attributions offered by actors and observers were attenuated but not eliminated when attributors had access to useful situational information with which to apply the discounting principle.     

Identifying the psychopath: The relation of Cleckley's criteria to the interpersonal domain

The relationship between interpersonal behaviour variables has been shown to be defined by a circular ordering, or circumplex, within the framework of a two-dimensional space. It is proposed that Cleckley's criteria of psychopathy represent one axis of this system, hostility vs warmth. It is also proposed that these criteria alone are not sufficient to identify a homogeneous group of deviant persons. Observer ratings of the behaviour of institutionalized mentally-disordered offenders were obtained for Cleckley's criteria and for behavioural dimensions of impulsive aggression and sociability. Cleckley's criteria were found to describe a unitary dimension whose relationship to other variables was consistent with the circumplex model. Cluster analysis of the ratings identified two distinct groups of high scorers on Cleckey's criteria, who were also significantly differentiated by self-report personality variables. Only one of these groups showed the combination of lack of warmth or affection and lack of behavioural control which several investigators consider necessary to define psychopathy. Relationships among individual rating items and some of the personality variables closely approximated the expected circular ordering. Reference to this interpersonal circumplex appears to reconcile some of the differences in current conceptualizations of psychopathic personality.     

Eysenck's theory of criminality and the personality types and offences of young delinquents

It has been proposed recently that the conflicting findings in studies of Eysenck's theory of criminality may be explicable in terms of the different personality subgroupings within the criminal population. It is proposed further that these different personality types may be associated with particular kinds of offences.The results of the present study confirm the existence of different personality types within a delinquent population. Four subgroups were identified, two of which were consistent with predictions from Eysenck's theory. The four subgroups could be distinguished on the basis of number of previous convictions but not by the kinds of offence committed. It is suggested, however, that future studies of this question, instead of examining kinds of offence committed, should focus their attention on situational components of the offences committed by the different personality subgroups.The general pattern of results is interpreted as supporting a modified or limited model of Eysenck's theory of criminality.     

Personality and sexuality

Although Eysenck's book Sex and Personality would seem to have broad implications for understanding sexual behavior, there has been relatively little empirical research that has attempted to test Eysenck's theory. The present research tested aspects of this theory by examining the correlations between personality characteristics and a variety of sexual attitudes and behavior in a sample of male Canadian college students. Results were, for the most part, supportive of Eysenck's theory. Extraverts were characterized by a hedonistic outlook on sex and by more active participation in a variety of sexual activities. High P scorers were characterized by more favorable attitudes to and enjoyment of force and unconventional sexual activities. Correlations with the N scale were, in general, not statistically significant. High L scores were associated with more negative attitudes toward sex, and lower reporting for virtually all types of sexual activity.
