The study examines the prevalence and correlates of DSM-IV Pathological Gambling (PG) using data from the National Comorbidity Survey Replication (NCS-R). It finds that while most respondents (78.4%) reported gambling at least once in their lives, only 2.3% had lifetime problem gambling and 0.6% met full PG criteria. PG was significantly associated with being young, male, and Non-Hispanic Black. People with PG reported first gambling significantly earlier than non-problem gamblers, with gambling problems typically beginning during the mid-20s and persisting for an average of 9.4 years. PG was predicted by prior anxiety, mood, impulse-control, and substance use disorders, and was associated with subsequent onset of generalized anxiety disorder, posttraumatic stress disorder, and substance dependence. Although none of the NCS-R respondents with PG ever received treatment for gambling problems, 49.0% were treated for other mental disorders. PG is a rare, seriously impairing, and under-treated disorder that typically starts during early adulthood and is frequently secondary to other mental or substance disorders. The study highlights the importance of understanding the temporal relationships between disorders and the need for further research to confirm these findings. The results are consistent with previous studies, showing a relatively low prevalence of PG and its high comorbidity with other disorders. The socio-demographic correlates found are consistent with previous research, and the study emphasizes the need for further research to confirm these associations. The study also notes the limitations of the data, including the reliance on retrospective reports and the small number of respondents diagnosed with PG. Overall, the study provides important insights into the prevalence and correlates of PG and its relationship with other mental disorders.The study examines the prevalence and correlates of DSM-IV Pathological Gambling (PG) using data from the National Comorbidity Survey Replication (NCS-R).
