The self-serving attributional bias was studied in matched groups of patients with persecutory delusions, patients with major affective disorder, and normal controls, (N = 14 in each group). On a preprogrammed computer task, subjects mainly won points in one condition and mainly lost points in the other. Subjects were asked to estimate the degree of control they thought they had over winning or losing in the two conditions. In comparison with the normal subjects and the psychiatric controls, the deluded subjects showed a greater self-serving bias, as evidenced by their perceived greater control over outcomes in the win condition. These findings are interpreted as consistent with the hypothesis that persecutory delusions function as a defense against low self-esteem.
在患有被害妄想症的患者、患有重度情感障碍的患者以及正常对照组的匹配组中（每组N = 14），对自利归因偏差进行了研究。在一个预编程的计算机任务中，受试者在一种情况下主要赢分，而在另一种情况下主要失分。受试者被要求估计他们认为自己在这两种情况下对输赢的控制程度。与正常受试者和精神科对照组相比，妄想症患者表现出更大的自利偏差，这体现在他们认为自己在赢的情况下对结果有更大的控制。这些发现被解释为与被害妄想症起到抵御自卑作用的假设相一致。
