Research output: Contribution to journalArticlepeer-review


This paper demonstrates that graphical chain models are a suitable statistical tool for investigating the complex structure of a psychiatric disease. The article is motivated by a crucial question arising in psychometric studies on pathological gambling: how are depression and anxiety associated and how do they determine the personality of a pathological gambler? Starting from an initial recursive structure that reduces the complexity of the data, graphical chain models investigate both direct associations and indirect dependencies among the psychometric scales measuring the personality traits. A "behavioral chain" acting in pathological gambling is suggested by the final chain resulted from the Cox and Wermuth variables selection strategy (Cox and Wermuth, 1996).
