“Prospection” refers to the ability to mentally simulate one's future episodes. Negative bias in prospection, which includes both reduced positivity and enhanced negativity, is considered to be closely related to the development and maintenance of depression. However, there is a relative paucity of measures that adequately assess negative bias in prospection in depressed people. The current study developed and initially validated the Negative Bias in Prospection Scale (NBPS) using a nonclinical sample (n = 959). The validity and reliability of the NBPS were investigated in several ways. Results suggested the 14 NBPS items loaded onto three factors, namely the “Increased negativity,” the “Reduced positivity,” and the “Overgeneralization.” The NBPS demonstrated decent internal consistency and test–retest reliability. Further, the NBPS was strongly associated with severity of depressive symptoms. Moreover, the NBPS was correlated in a theoretically meaningful way with other measures of future‐oriented cognitions or negative biases. In conclusion, the NBPS has promising preliminary psychometric properties. It will be an efficient tool for exploring dysfunctional prospection in depression and provides a novel measure for mechanism of change in prospection‐based interventions.
