Sample Diagnosis |
DSM-IV |
Related Diagnostic Tools |
PTSD diagnosis was assessed via telephone using a structured diagnostic interview validated against the Clinician-Administered PTSD Scale for DSM-IV (CAPS), Participants were initially asked to identify potentially traumatic events (PTEs) that they experienced in the past from a list of 19 events, PTS severity was assessed by summing participants' ratings of the 17 posttraumatic symptoms on a scale indicating the degree to which the respondent had been bothered by a particular symptom as a result of the worst trauma, ranging from 1 (not at all) to 5 (extremely), Depressive symptoms were evaluated with a structured interview based on a modified version of Patient Health Questionnaire (PHQ-9), CM questions were drawn from the Conflict Tactics Scale (CTS), the Childhood Trauma Scale (CTQ), and Wyatt's eight-item interview guide as implemented by the Nurse's Health Study II. |
Sample Status |
Samples for this study were drawn from the Detroit Neighborhood Health Study (DNHS). The DNHS is a population-representative cohort study of adult residents residing in Detroit and has been described. |

Result Summary |
RESULTS: No significant main effects were observed for ADCYAP1R1 genotype on either PTSD/PTS severity. In contrast, a significant ADCYAP1R1 x CM interaction was observed for both past month PTSD and PTS severity, with carriers of the "C" allele showing enhanced risk for these outcomes among women exposed to CM. No significant main or interaction effects were observed for past month depression/depression severity. CONCLUSIONS: Genetic variation at the ADCYAP1R1 locus interacts with CM to shape risk of later PTSD, but not depression, among women. The molecular mechanisms contributing to this interaction require further investigation. |

Stratification by ADCYAP1R1 genotype showed that these correlations were significant only among genotypes containing the "C" allele. Moreover, correlation coefficients were significantly higher in the CC versus GG group and in the CC versus CG group.

Results from interaction effect analyses showed that participants with one versus no "C" alleles at the ADCAYP1R1 rs2267735 locus showed a 17% increased odds of past month PTSD for every one-unit increase in CM score in the logistic regression model. Analyses based on African-American participants only showed similar results.
