Differences between schizophrenic patients with Schneiderian first-rank symptoms (FRS) and those without FRS at the time of hospitalization indicated FRS were associated with behavior consistent with feelings of passivity and helplessness. The two groups responded equally well to treatment in a therapeutic community. Findings support the contention that FRS are not pathognomonic or prognostic in schizophrenia.
住院时具有施奈德首级症状（FRS）的精神分裂症患者与无FRS的患者之间的差异表明，FRS与被动感和无助感一致的行为相关。在治疗社区中，两组对治疗的反应同样良好。研究结果支持了FRS在精神分裂症中并非具有诊断特异性或预后意义的这一观点。
