- Background: Reduced central serotonergic neurotransmission has been demonstrated in individuals with excessive alcohol consumption and/or alcohol dependence. Childhood maltreatment has also been found to have a negative impact on central serotonergic neurotransmission. The aim of this study was to evaluate the impact of childhood maltreatment on central serotonergic dysfunction in alcohol-dependent individuals.Methods: Adult men with a diagnosis of alcohol dependence (n=18) were recruited from outpatient treatment units for alcoholism. Central serotonergic neurotransmission was assessed by a neuroendocrine method, that is, the prolactin (PRL) response to the selective 5-HT reuptake inhibitor citalopram. Childhood maltreatment was assessed retrospectively by the Childhood Trauma Questionnaire.Results: Alcohol-dependent individuals with childhood experience of emotional abuse had significantly lower PRL response compared with those without such abuse (3 +/- 5 and 64 +/- 24mU/l, respectively; t=6.51, p<0.001). Among those who reported childhood emotional abuse, 4 of 7 individuals had flat PRL responses in comparison with none in those with no report of such abuse (p<0.01).Conclusions: This is the first study to show that self-reported childhood maltreatment, in particular emotional abuse, in male alcohol-dependent individuals is associated with a quite dramatic (more than 90%) reduction in central serotonergic neurotransmission. It should, however, be noted that the number of individuals is relatively small, and the results should therefore be considered as preliminary.

- Childhood maltreatment has diverse, lifelong impact on morbidity and mortality. The Childhood Trauma Questionnaire (CTQ) is one of the most commonly used scales to assess and quantify these experiences and their impact. Curiously, despite very widespread use of the CTQ, scores on its Minimization-Denial (MD) subscale-originally designed to assess a positive response bias-are rarely reported. Hence, little is known about this measure. If response biases are either common or consequential, current practices of ignoring the MD scale deserve revision. Therewith, we designed a study to investigate 3 aspects of minimization, as defined by the CTQ's MD scale: 1) its prevalence; 2) its latent structure; and finally 3) whether minimization moderates the CTQ's discriminative validity in terms of distinguishing between psychiatric patients and community volunteers. Archival, item-level CTQ data from 24 multinational samples were combined for a total of 19,652 participants. Analyses indicated: 1) minimization is common; 2) minimization functions as a continuous construct; and 3) high MD scores attenuate the ability of the CTQ to distinguish between psychiatric patients and community volunteers. Overall, results suggest that a minimizing response bias-as detected by the MD subscale-has a small but significant moderating effect on the CTQ's discriminative validity. Results also may suggest that some prior analyses of maltreatment rates or the effects of early maltreatment that have used the CTQ may have underestimated its incidence and impact. We caution researchers and clinicians about the widespread practice of using the CTQ without the MD or collecting MD data but failing to assess and control for its effects on outcomes or dependent variables.
