Abstract

Trauma researchers have recently begun using Amazon's Mechanical Turk (MTurk) as a data collection platform that is both time- and cost-efficient. Research is needed to determine the utility, generalizability, and validity of MTurk as a recruitment source for trauma-exposed samples. Data were collected from 266 trauma-exposed MTurk participants on several clinical and psychological constructs relevant to trauma research. The mean scores, prevalence rates, and correlation strengths of the MTurk sample were compared to those reported in previously published studies of undergraduate, community, and treatment-seeking samples. Findings indicated that prevalence rates of posttraumatic stress disorder (PTSD) and depression were not significantly different from comparison samples, but prevalence rates of generalized anxiety were significantly higher than that of a community sample. The MTurk sample showed significantly lower mean scores of PTSD, depression, and generalized anxiety symptoms than all comparison samples. Correlations were examined to determine whether established relationships between common trauma-related constructs were correlated for MTurk participants as they were in other samples. Correlations between PTSD symptom se...Continue Reading
