Bipolar disorder and risk for mania are associated with setting high goals and dysregulated goal pursuit. One mechanism mediating between setting high goals and manic symptoms could be daydreaming or more generally, mental imagery. 'Daydreams' (as one form of mental imagery) are characterized by the fact that the content is produced deliberately. Akiskal et al. (1995) reported that daydreaming prospectively predicted a switch from unipolar depression to bipolar disorder. We here hypothesized that risk for mania should also be associated with increased daydreaming after controlling for depression.
N=249 participants from a non-clinical, community sample completed several self-report measures including the Hypomanic Personality scale and Daydreaming scale.
Hierarchical regression revealed that risk for mania predicted daydreaming after controlling for current and former depression.
Only self-report measures were used. The sample was a non-clinical, primarily White British sample, which has implications for generalizability.
Despite limitations our results support the hypothesis that vulnerability for mania is associated with daydreaming. Daydreaming was related to mania and depression which highlights that it might be relevant for the etiology or maintenance of mood disorders.
双相情感障碍和躁狂风险与设定高目标和目标追求失调有关。在设定高目标和躁狂症状之间起中介作用的一种机制可能是白日梦，或者更广泛地说是心理意象。“白日梦”（作为心理意象的一种形式）的特点是内容是故意产生的。Akiskal 等人（1995 年）报告说，白日梦前瞻性地预测了从单相抑郁到双相情感障碍的转变。我们在这里假设，在控制抑郁后，躁狂风险也应该与增加的白日梦有关。
来自非临床社区样本的 249 名参与者完成了几项自我报告措施，包括躁狂人格量表和白日梦量表。
分层回归显示，在控制当前和以前的抑郁后，躁狂风险预测了白日梦。
仅使用了自我报告措施。该样本是一个非临床的、主要是白种英国人的样本，这对推广有影响。
尽管存在局限性，但我们的结果支持这样一种假设，即躁狂易感性与白日梦有关。白日梦与躁狂和抑郁有关，这突出表明它可能与情绪障碍的病因或维持有关。
