Like other writers before them (whom they do not cite), Straub, Grunberg, Street & Singer (1990) claim it as a discovery that "A-B" predicts dominance. They fail to note that many items in the scale used to score "A-B" express a tendency towards dominant behavior and that dominance has long ago been shown as one of the major factors of the said scale. Their alleged finding is therefore merely an artifact and shows primarily their ignorance of the literature.

"A-B" not relevant to heart disease

Now that it is fairly clear (Appels, Mulder & Van Houtem, 1985; Davis & Cowles, 1985; Diamond, 1982; Emara, El-Islam, Abu Dagga & Moussa, 1986; Goldstein, Edelberg, Meier, Orzano & Blaufuss, 1985; Heilbrun, Palchanis & Friedberg, 1986; Houston & Snyder, 1988; Katz & Toben, 1986; Lelouch & Kornitzer, 1982; Linden, 1987; Mathews, 1982; Myrtek & Greenlee, 1984; Nanjundappa, Friis & Taladrid, 1987; Ray, 1986; Ruberman, Weinblatt, Goldberg & Chandbury, 1984; Shekelle, Hulley, Neaton et al., 1985; Young, Barboriak, Hoffman & Anderson, 1984) that "A-B" personality type does not give any consistent or long-term prediction of proneness to coronary heart disease (CHD), one would think that the concept would no longer have any interest for psychologists. The concept did, after all, come into existence purely on the basis of its claim to be the coronary-prone personality pattern. Predicting CHD was, in other words, its whole raison d'etre. What little theory attached to the concept was wholly subordinate to that aim. This can perhaps best be seen by the way the concept is named. No word in the whole English language was deemed adequate as a descriptor for the concept. All we have are "As" who are allegedly coronary-prone and "Bs" who are allegedly not coronary-prone. Now that we know "As" and "Bs" to be equally likely to be coronary-prone, the whole concept therefore surely falls apart.

As it is, however, the more the concept fails its basic validity test, the more psychologists seem to take an interest in it. Almost any journal one picks up nowadays seems to have at least one article on it. This need not necessarily be a bad thing. Promoters of the concept give considerable stress to the speed-and-impatience (SI) aspect of it and the concept of speed-and-impatience does appear fairly original and of potential interest outside its original application.

Speed and Impatience

It may be noted that "A-B" is normally measured by the Jenkins Activity Survey (JAS) rather than by the Structured Interview (Yarnold & Bryant [1988] give some inkling of the validity horrors attendant on using the Structured Interview) and the JAS does come complete with a defined factor structure of which SI is one out of three factors. Even the test manual for the JAS (Jenkins, Rosenman & Zyzanski, 1979), however, shows that the SI factor does not predict CHD, so the emphasis that has been given to this part of the concept as a predictor of CHD is more than a little puzzling.

Nonetheless, a focus on SI by itself could be seen as having some interest. The other items of the JAS seem, on inspection, to reflect themes already well-known in psychology -- achievement-motivation, dominance, anxiety, extraversion, hostility etc. Psychologists hardly need new instruments to study those concepts. Only the JAS, however, offers a measure of SI.

"A-B" and dominance

Despite that, studies appearing in the literature that use the JAS generally seem to focus on the discredited "A-B" concept rather than on its potentially interesting SI subfactor. A recent study appearing in this journal (Straub, Grunberg, Street & Singer, 1990) is merely one example of that. Straub et al, are, however, more naive than most. Like Yarnold & Grimm (1986) and Yarnold Mueser & Grimm (1985) before them (whom they do not cite), they report the "discovery" that "A" types tend to be dominant. Since the JAS contains so many items that express a tendency towards dominance, this is very much an artifactual finding -- a pseudo-discovery. Had Straub et al just once looked at the instrument they were using they would surely have realized the pointlessness of what they were doing. They would have seen that they were simply using items that acknowleged a tendency towards dominant behaviour to predict tendency towards dominant behaviour. That is much more ho-hum than what they seemed to think that they were doing.

Previous work

If any proof is needed to show that the JAS is heavily weighted by items that express dominance, it may be found in a study by Ray & Bozek (1980). In that study, the items of the JAS were combined with the dominance and achievement motivation scales from the Jackson (1967) PRF and items from the Eysenck & Eysenck (1963) Impulsiveness scale. Almost all the items of the JAS loaded on the factors defined by the Jackson dominance and achievement motivation items. (A small minority loaded on a third factor which also loaded some of the Eysenck impulsiveness items. This third factor would appear to be similar to the original SI factor). It is very clear, then, that Straub et al have shown only that dominance scales tend to predict dominance. This is a much lesser finding than the one they claim. The fact that they are not the first to make the mistake they do (See the comments on Yarnold's work in Ray, 1988) is also a little discouraging.
