  • 19. Similarity measures• Rescaled D-score (D) • Elevation + Scatter of profiles • Cf. Euclidean distance •• Pearson correlation (r) • Shape of profiles •• Intraclass correlation (ICCDE) • Elevation + Scatter + Shape • Furr, 2009Koen De Couck 19Psychometrics Centre, Cambridge

Sig effect C+, p<0.05•Married: • Logistic regression: sig. effect of individual’s O-, C+, N+, p<.001• Point-biserial correlations: • All traits: ~ .03 (relationship) • C: r = 0.12 (married)Koen De Couck 26Psychometrics Centre, Cambridge
  • 27. Are gay couples more similar in personality?• n = 188• In gay couples, ICCDE similarity scores (MICC = 0.29, SDICC = 0.42) are significantlyhigher than for straight couples (MICC = 0.18, SDICC = 0.45): tICC (199.188) = 3.369, p < .001• Not merely (lack of) gender difference !• Difference to Partner – Stranger is also higher for gay couples than for straight couples• Shape of personality profile• Not found for lesbian couplesKoen De Couck 27Psychometrics Centre, Cambridge
  • 28. Hypotheses• Hypothesis: “The degree of personality similaritypredicts the quality of the relationship” • Similarity reduces in marriages • Arranged marriages, other research• Hypothesis: “Selection for personality occurs infunction of potential mate presence (i.e. can youafford to be choosy?)” • No relation #friends – ICC • However… • ICC in gay couples = .30 ≠ heterosexual couples (ICC = .18) • Population density (city vs rural areas)Koen De Couck 28Psychometrics Centre, Cambridge
  • 29. How about IQ ?• Correlation IQ: r = 0.30, p = 0.003 (Mean = 113, n = 93 couples) • = Correlation personality !*• IQ difference: 13 points, sd: 7 (n = 23 couples)Koen De Couck 29Psychometrics Centre, Cambridge
