Abstract
OBJECTIVES: Procrastination is typically assessed via self-report questionnaires. So far, only very few studies have examined actual procrastination behavior, providing inconclusive results regarding the real-life validity of self-reports in this domain. The present study aimed to examine for the first time whether participants' self-reported procrastination can predict their actual behavior on a real-life task. METHODS: For that purpose, we assessed self-reported levels of procrastination [via the Pure Procrastination Scale, PPS] and actual procrastination behavior on a naturalistic task [i.e., having to send in an attendance sheet before a deadline] in 93 participants. RESULTS: Results show that self-reports significantly predicted procrastination behavior. Analyses of underlying dimensions suggest that real-life procrastination can be the result of "voluntarily delaying planned actions," but can also have more passive causes such as "running out of time." CONCLUSIONS: Comparing our results with the available literature suggests that PPS self-reports reflect a particularly valid tool to assess real-life procrastination behavior. Findings are discussed in the context of strategies and mechanisms that potential interventions may target in order to reduce procrastination.
