Results Of The ABO System

<Primaries>

Factor Q2

• Low-Score Description: GROUP ADHERENCE
  • Group-dependent
  • A "joiner" and sound follower
• High-Score Description: SELF -SUFFICIENCY
  • Self-sufficient
  • Resourceful
  • Prefers own decisions
• Scores:
  • B  10.807 N=32
  • A  11.778 N=131
  • O  11.866 N=148
  • AB 14.392  N=12
• AB has significantly larger (p<0.05) more than A or B but not O.  Group B, A and O have homogeneous means.

Factor Q3

• Low-Score Description: LOW SELF-SENTIMENT INTEGRATION
  • Undisciplined self-conflict
  • Lax
  • Follows own urges
  • Careless of social rules
• High-Score Description: HIGH STRENGTH OF
  • Controlled
  • Exacting will power
  • Socially precise
  • Compulsive
  • Following self-image
• Scores:
  • A  8.451 <N=131)
  • AB 9.573 (N=12)
  • O  9.591 (N=148)
  • B 10.075 (N=32)
• A has a significantly lower (p<0.01) mean then O and B, but not from AB. Group AB, O, and B have homogeneous means.

<Secondaries>

Factor QII

• ANXIETY (This is pure anxiety and not to be confused with the neurotic anxiety in some "anxiety" scales.)
• Scores:
  • O -.660 (N=148)
  • B -.550 (N=32)
  • AB 0.713 (N=12)
  • A  0.812 (N=131)
• Group A and O are significantly different from eath other (p<0.01) but group O is not significantly different from B and AB, nor group A significantly different from B and AB.

Summary

• TYPE-AB is more self-sufficient and group-independent (probability < 5 percents)
• TYPE-A is more anxious than TYPE-O (probability < 1 percent)

Subjects And Methods

Subjects were unrelated Caucasian Australian residents. The 156 males and 167 females were drawn from employees of the Commonwealth Serum Laboratories (164), volunteers from the community in response to radio or personal appeals (96) and Royal Melbourne Hospital personnel (63). The mean age was 35.2 with a standard deviation of 16.3 years.
Blood was collected in sterile containers and allowed to coagulate. The separated serum was kept frozen at -70 degrees and clots, washed free from adhering white cells and serum using physiological saline (16), were stored at -20 degrees. Residual crythrocytes bathed in serum were retained at 4 degrees for blood typing. The 17 systems involved in the study are listed in table 1

Note: Factor B, intelligence, although not one of the 15 personality factors, being an ability measure, is in its usual position here in the 16 PF scales.

Summary

A sample of 323 Caucasian Australians was characterized with respect to 17 genetic systems (7 blood groups, 5 crythrocyte enzymes and 5 plasma proteins) and 21 psychological variables (16 primary and 5 secondary personality factors). The mean age corrected psychological scores were determined for each phenotype and comparisons within systems yielded 13 significant differences a to .05 level and 11 at .01 level. The most conclusive finding occurred in the P system: the four primaries producing differences a to .01 level (C, H, Q3, and Q4) are those entering into the second order anxiety factor QII, which yielded the greatest difference observed in the study (p<.001).
