Feedback for To understand the relationship between childhood traumatic experiences and the sensory complexity of hallucinations, a cohort of 75 children and adolescents seeking help for hallucinations were studied. To determine the extent by which the various sensory modalities could predict the probability of a previous early trauma, the authors employed a hierarchical binomial logistic regression with history of childhood trauma as the binary dependent variable with control variables (i.e., age, educational level and number of ICD-10 diagnoses, the presence of suicidal ideation), and the number of hallucinatory modalities as predictors. The number of hallucinatory modalities appeared to be the only significant predictor of childhood trauma (estimate (i.e. the log odds of ‘history of childhood trauma’ = 1 v. 0) 0.81, s.e. = 0.34, z = 2.39, P = 0.017, OR = 2.24 (95% CI 1.16–4.33). The predictor that emerged as statistically significant variable is most likely a/an?
