The interventions will be delivered online in group settings. Both protocols include identical psychoeducation and cognitive modules aiming at identification and modification of dysfunctional automatic thoughts related to procrastination but will differ in the behavioral modules. The behavioral module in the first protocol is focused on timely beginning and realistic planning. The second protocol implements working time restriction. The wait-list control group will receive one of the CBT protocols after a waiting period that will last as long as the CBT intervention and the assessments performed directly after treatment. It is assumed that the interventions will be superior to the wait-list control. Primary (procrastination) and secondary (depression and anxiety) measures will be collected prior to and after the interventions (or waiting period in the wait-list group) and after 6 months in the two active condition groups. Additionally, neuroimaging measurements will be conducted before and after the interventions (or waiting period in the wait-list group). Approximately half of the participants will undergo functional Magnetic Resonance Imaging (fMRI), and another half will undergo electroencephalography (EEG). Both methods are aimed at exploring neural correlates of the expected improvements in participants' self-regulation abilities., conditionsModule conditions: Procrastination, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: PARALLEL, primaryPurpose: TREATMENT, maskingInfo masking: SINGLE, maskingDescription: A researcher not having direct contact with participants will create a script generating random sequence using a computer random sequence generator (Matlab). Randomization will take place at an individual level, stratified by age, gender and procrastination severity (block randomization). Participants will be randomized into three groups with an allocation ratio of 1:1:1.Pairs of experienced psychotherapists trained in one of the therapy protocols will deliver the interventions in an online group setting., whoMasked: PARTICIPANT, enrollmentInfo count: 276, type: ESTIMATED, armsInterventionsModule interventions name: Psychoeducation and cognitive modules, interventions name: Behavioral module: Starting on Time and Planning Realistically, interventions name: Behavioral module: Working Time Restriction, outcomesModule primaryOutcomes measure: Change in Polish version of the Pure Procrastination Scale (PPS), primaryOutcomes measure: Change in Polish version of the Aitken Procrastination Inventory (API), secondaryOutcomes measure: Change in Polish version of the Patient Health Questionnaire (PHQ-9), secondaryOutcomes measure: Change in Polish version of the Generalized Anxiety Disorder Questionnaire-7 (GAD-7), secondaryOutcomes measure: Percentage of completion of a particular project that the participant decided to work on during the training (e.g. a thesis, an essay, a report)., otherOutcomes measure: Change in Polish version of the Sensitivity to Punishment and Sensitivity to Reward Questionnaire - Short Form (SPSRQ-SF), otherOutcomes measure: Change in Polish version of the Multidimensional-Multiattributional Causality Scale (MMCS), otherOutcomes measure: Change in Polish version of the Performance Failure Appraisal Inventory (PFAI), otherOutcomes measure: Change in Polish version of the Difficulties in Emotion Regulation questionnaire (DERS), otherOutcomes measure: Change in Polish version of the Motivation Diagnostic Test (MDT), otherOutcomes measure: Change in Polish version of the Zimbardo Time Perspective Inventory, otherOutcomes measure: Change in Polish version of the Metacognitive Beliefs about Procrastination Questionnaire (MBPQ), otherOutcomes measure: Change in Polish version of the Impulsivity Scale (UPPS-P), otherOutcomes measure: Change in Polish version of the Self-control Scale (NAS-50), otherOutcomes measure: Change in Polish version of the Procrastination Diagnostic Criteria Questionnaires (PDCQ), otherOutcomes measure: Change in Polish version of Positive and Negative Affect Schedule (PANAS) in relation to a project that the participant decided to work on during the training (e.g. a thesis, an essay, a report), otherOutcomes measure: Polish version of the Group Session Rating Scale (GSRS), otherOutcomes measure: Several items concerning homework compliance (cf.
