This study examined the extent to which boredom proneness and sleep disturbances were related to attention-deficit scores in college-aged students.  In a sample of 148 college students, Attention scores on the Adult Behavior Checklist were best predicted by boredom proneness (BP) subscale scores, which assess one's inability to maintain internal internal stimulation and feelings of constraint, and scores on the Epworth Daytime Sleepiness Scale and Athens Insomnia Scale (R2 = .57).  Hyperactivity scores were best predicted by the BP subscale, which assess one's need for a stimulating environment, the perception of time passing slowly, and feelings of constraint and the Epworth Scale (R2 = .51).  The findings contribute to the understanding of the symptomatology of attention deficit in adults and provide further evidence of the validity of this measure
