“…This is not to imply that the stress experienced by procrastinators does not involve changes in immune functioning that may compromise health. Indeed, the association between negative mood states and procrastination is well established (Beswick et al, 1988;Ferrari, Johnson, & McCown, 1995;Martin et al, 1996;Pychyl, Lee, Thibodeau, & Blunt, 2000;Senecal et al, 1995;Solomon & Rothblum, 1984), and these affective changes are known to negatively impact immune system functioning (e.g., Cohen et al, 1995;Irwin, Daniels, Smith, Bloom, & Weiner, 1987). However, according to Milgram (1991) the emotional upset experienced by procrastinators is a result of the behavior sequence of postponement; therefore, these negative mood states are largely the result of the behavioral manifestations of procrastination rather than the cause of the dilatory behavior.…”
