Results for the final SEM again indicated good model fit, TLI = .94, RMSEA = .05 (χ2(47) = 71.88). The MTI Detachment factor at age 17 Time 1 was significantly correlated with the Family Functioning factor (r = −.25, p < .01), and the MTI Antisocial factor at age 17 Time 1 was significantly correlated with the Externalizing factor (r = .42, p < .001). The Family and Externalizing factors were significantly correlated (r = −.31, p < .01). The factor correlations between the Family and MTI Antisocial (r = −.17) and Externalizing and MTI Detachment (r = .13) factors did not reach conventional levels of significance (p = .07–.09). Finally, there were no significant predictive effects of the Family or Externalizing factors on the age 23 Time 2 MTI Detachment or Antisocial factors. That is, conventional SEM statistical procedures for determining parameter significance indicated that these latter parameters were not different from zero (ps > .05). As such, only the baseline MTI psychopathy factors were significant predictors of their respective follow-up MTI psychopathy factors.
