A CLUSTER ANALYTIC EXPLORATION OF WHAT UNDERLIES POPULAR SOCIAL SCIENCE CONSTRUCTS*



University of New South Wales, Australia

JOHN J. RAY

SUMMARY

A set of short scales measuring authoritarianism, dogmatism, locus of control, other-directedness, alienation, neuroticism, achievement motivation, social desirability response set, and machiavellianism was administered to a quota sample in the Sydney metropolitan area, Australia (N = 87). Under cluster analysis, the items fell into three second-order clusters identifiable as measuring personal adjustment, achievement motivation, and cynicism. It was concluded that for research to be widely noted among psychologists it probably would have to be concerned with variations on one of those three themes.

INTRODUCTION

Of the many thousands of attitude and personality scales in existence, it is notable how only a very small number seem to see repeated use. One can detect that some constructs in psychology and sociology are vastly more fashionable or popular than others. In the '50s and '60s the example par excellence of this was, of course, authoritarianism measured by the California F scale. The best example currently seems to be the Rotter locus of control scale.

The present study is an attempt to see what underlies such constructs. What does it take to make a construct popular? Are the popular constructs themselves reducible to an even smaller descriptive universe? Do they have a genuine life of their own or are they only slight variations on long-known and universal themes?

The efforts of Cattell (1) and Eysenck (2) are well-known in this field. They, however, aspire to explore the whole domain of personality with a view to describing characteristic human behavior as economically as possible. The aspiration here is much different: what is attempted is to explore the interests of the psychologist himself. What do those constructs that appeal to him have in common? Unlike the aim of the work of Eysenck or Cattell, the expectation underlying the present work is that the factors revealed will not cover the whole of the person-descriptive universe.

B. METHOD

The constructs chosen for examination were: authoritarianism, dogmatism, locus of control, other-directedness, alienation, neuroticism, achievement motivation, approval motivation (social desirability response set), and Machiavellianism.

Scales to measure these constructs were assembled and administered to a quota sample of 87 people from the population of Sydney, Australia. As some of the results from this study have already been reported elsewhere (12, 13, 14), details of the sampling and full references for the scales will not be repeated here. Suffice it to say that although the sample was small, its community-based character was thought to give it some interest when compared with the more usual sample of students.

To control for possible format effects, it was thought important that all scales be in common format. As all were available in Likert format, this was the format chosen. Because the large number of constructs would normally require a very long questionnaire with its attendant deleterious effect on response-rate (only highly co-operative people might be sampled), all scales were reduced to short forms. In all cases except that of Kassarjian's Other-Directedness scale (4), item-analyses were available to facilitate this: only the items correlating most highly with the original scale totals were chosen. Because of the uncertainty involved with the Kassarjian items, 12 of these were administered (compared with six to 10 for the other scales). Of the other scales, it should perhaps be noted that authoritarianism was measured by a behavior inventory [the Ray "Directiveness" scale (11)] rather than by the more usual (but less valid) attitude scale and that alienation was measured by the Ray "GA" scale (10). This latter scale represents a distillation from the sum total of all published items said to measure alienation or some related construct that could be found in the published literature.

C. RESULTS

The 86 scale items were subjected to cluster analysis which is preferred to factor analysis for the reasons given at some length in Ray (8): in general it yields factors that are more easily interpretable.

Only three second-order clusters emerged. These were subjected to conventional Likert scale item analysis to obtain criteria for how central each item was to the cluster as a whole. Weakly loading items (items showing a low item-total correlation) were deleted from further consideration in order to help sharpen the conceptual identity of each cluster. When this was done, three quite reliable scales emerged which rather clearly measured Personal Adjustment, Achievement Motivation, and Cynicism. Their coefficient "alpha" reliabilities were, respectively, .84, .77, and .78. The lengths of these scales were decided by the point in the iterative item analysis at which reliability ("alpha") ceased to rise: if further weak items had been deleted, the reliabilities would have been less and if further weak items had been retained the reliability would also have been less. See Ray (7).

D. DISCUSSION

The cluster analytic technique employed above is an extremely simple one, well justifying its name as "Elementary factor analysis" (5). It uses the highest correlation coefficient in each vector of the zero order matrix and, as such, does not even give "loadings" for each item. It gives only the information of how many clusters there are and which cluster each item fits best. To remedy this lack of loadings, each cluster was treated as a summative scale and subjected to standard item-analysis techniques. The item-to-total correlations become thus equivalent to centroid loadings.

Although much less popular than factor analysis, cluster analysis has many devotees who claim that it gives clearer, more "interpretable" results (e.g., 3, 6, 15). The present results would seem to represent further vindication for that claim, since the structure revealed is certainly very easily identifiable. One explanation might be that the method used above has some claims to being less affected by the problem of "error correlation." Ordinary factor analysis must try to make sense of all the correlations in the matrix, many of which contain very little "true" variance and all of which contain at least some "error" variance. By using only the highest correlations, the McQuitty method would seem to maximize the chances of the analysis being based only on correlations which had at least some "true" variance. The normal way of dealing with the error variance problem in factor analysis is to advocate that N should be large, thus maximizing the chances that error variance will be randomized out. Because, on the above reasoning, the McQuitty method has other means of dealing with the error problem, the N planned for on the present occasion could reasonably be small. The results would seem to justify the view that a large N was not required to give a clear and theoretically meaningful structure.

Although intended solely as an exploratory study, the present work can be seen as giving some support to the view that the constructs popular among social psychologists tend to be little more than ponderous relabellings of quite simple and familiar concepts. Thus the California F scale might be regarded as just another conservatism scale (9) and the I-E scale as just a "belief in luck" scale. Achievement motivation could more simply be called "ambition." Such simplifications will of course not readily secure assent, but by empirically pulling apart many different scales and rearranging their items in three simple, easily recognizable groups, the present results show that they are indeed possible.

What, then, if anything, do the present results suggest about the interests of the social scientist? Conceivably, it tells us that he is achievement motivated, fascinated by personal adjustment/maladjustment, and probably rather cynical in his beliefs about the world around him. To claim this, however, is to assume that what captures his interest are things that are of personal concern to him, that people who are interested in ambition will be ambitious, etc. The converse, of course, may be true. One may be fascinated by a phenomenon that one does not share in.

The three themes demonstrated in the present analysis may also serve as a guide to the sorts of studies of interest to one's colleagues. The value of this diagnosis in the era of grantsmanship and publish-or-perish is probably obvious if we are in some indecision about where to direct our research activities. Projects concerned with some variation on one of the three themes of achievement motivation, adjustment/maladjustment or cynicism/trust are likely to receive the warmest reception.

POST-PUBLICATION ADDENDUM

Replication is one of the cornerstones of science. A new research result will normally require replication by later researchers before the truth and accuracy of the observation concerned is generally accepted. If a result is to be replicated, however, careful specification of the original research procedure is important.

In questionnaire research it has been my observation that the results are fairly robust as to questionnaire format. It is the content of the question that matters rather than how the question is presented (But see here). It is nonetheless obviously desirable for an attempted replication to follow the original procedure as closely as possible so I have given here samples of how I presented my questionnaires in most of the research I did. On all occasions, respondents were asked to circle a number to indicate their response.
