“…In fact, it emerges that the drug-dependent subjects express at the highest level the differences in NS, HA, and SD that have been found in the HIV population compared with the control group. This profile indicates the presence of a borderline or passive-aggressive personality profile [15, 16], according to the literature about drug-dependent subjects [1, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28]. These personality traits, presumably related to the development of a drug dependence [28], may be relevant for the risk of HIV infection [29], for the difficult clinical management of drug-dependent HIV-positive subjects, and for the less consistent benefits from psychotherapy [12, 13, 14].…”
