从跨诊断强迫性到临床应用：计算精神病学在研究与临床之间的桥梁

Compulsivity, the maladaptive persistence of behaviour despite adverse consequences, is central to obsessive-compulsive disorder (OCD) and has been increasingly conceptualised as a transdiagnostic dimension spanning multiple neuropsychiatric disorders. Research within computational psychiatry has linked dimensional compulsivity to two candidate mechanisms: impaired goal-directed control and elevated metacognitive confidence. Here, we take a clinical perspective addressing how insights from these findings can be brought into practice. We first ask how dimensional compulsivity measures should be
