Contribution of interoceptive bodily dimensions to schizotypal traits. PLSR out-of-sample prediction of SPQ traits shows significant correlations between true and predicted values (R and p values reported). (a) SPQ-I: Regression weights for interoceptive variables (3 M, 4 M, 5 M, 8 M, BPQ-SUP, Con-d, Acc-c, Con-c). (b) SPQ-D: Regression weights for interoceptive variables (8 M, BPQ-SUP). Only weights exceeding the 95% confidence interval of the null hypothesis are reported. See Table 1 for full names of predictor variables.
