The aim of this study is to compare the efficacy of and the neural changes following two cognitive behavior therapy (CBT) protocols for procrastination with a wait-list control group. 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.

Psychoeducation and cognitive modules: what is procrastination, role of rewards, work environment, belief identification, cognitive restructuring, relapse prevention.
Learning of realistic planning, and timely starting of work.
Restriction of allowed time for work, and gradual increase of allowed time, if previous time windows where effectively used.

RECRUITINGChange in Polish version of the Pure Procrastination Scale (PPS)
Assessment of procrastination level. The Polish version of PPS consists of 12 items that evaluate procrastination conceptualized as a dysfunctional delay (e.g. "I am continually saying I'll do it tomorrow"; "I delay making decisions until it's too late"). Participants respond on a 5-point scale (1 = "very seldom or not true of me"; 2 = "seldom true of me"; 3 = "sometimes true of me"; 4 = "often true of me"; 5 = "very often true of true of me")
Time frame: baseline assessment (week 0); mid-treatment assessment (week 3); post-treatment assessment (week 6); follow-up assessment (6 months after post-treatment assessment)
Change in Polish version of the Aitken Procrastination Inventory (API)
Assessment of academic procrastination level. The Polish version of API consists of 19 items that evaluate the tendency of students to procrastinate in their academic tasks (e.g. "If I had an important project to do, I'd get started on it as quickly as possible", "Getting down to work often takes me a long time."). Participants respond on a 5-point scale (1 = "false"; 2 = "mostly false"; 3 = " sometimes false/sometimes true"; 4 = "mostly true"; 5 = "true").
Time frame: baseline assessment (week 0); mid-treatment assessment (week 3); post-treatment assessment (week 6); follow-up assessment (6 months after post-treatment assessment)
Change in Polish version of the Patient Health Questionnaire (PHQ-9)
Assessment of depressive symptoms. The Polish version of PHQ-9 consists of 9 items that evaluate the occurrence of depressive symptoms in the last 2 weeks (e.g. "Little interest or enjoyment of your activities"). Participants respond on a 4-point Likert scale (0 = "not at all"; 1 = "on a few days"; 2 = "on more than half of the days"; 3 = "nearly every day").
Time frame: baseline assessment (week 0); mid-treatment assessment (week 3); post-treatment assessment (week 6); follow-up assessment (6 months after post-treatment assessment)
Change in Polish version of the Generalized Anxiety Disorder Questionnaire-7 (GAD-7)
Assessment of anxiety symptoms. The Polish version of GAD-7 consists of 7 items that evaluate the occurrence of anxiety and excessive worry symptoms in the last 2 weeks (e.g. "Feeling afraid as if something awful might happen"). Participants respond on a 4-point Likert scale (0 = "not at all"; 1 = "on a few days"; 2 = "on more than half of the days"; 3 = "nearly every day").
Time frame: baseline assessment (week 0); mid-treatment assessment (week 3); post-treatment assessment (week 6); follow-up assessment (6 months after post-treatment assessment)
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).
Before and after therapy they will be asked to assess the percentage of the project that has been completed. The higher the difference between the two assessments the better the outcome.
Time frame: baseline assessment (week 0); mid-treatment assessment (week 3); post-treatment assessment (week 6)
