Randomised Controlled Trial of a Digital Programme for Procrastination in UK University Students

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to evaluate the effect of an 8-week self-directed internet based CBT intervention on various psychological outcomes for young students struggling with procrastination in the UK. The psychological outcomes consist of motivation, depressive symptoms, impulsivity and anxiety. More specifically, the study aims to compare the effect of the intervention vs waitlist control at 8 weeks on primary and secondary outcomes. Additionally, the study aims to explore whether changes in primary and secondary outcomes as the result of the intervention are mediated or moderated by key intervention processes.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Procrastination: Pure Procrastination Scale (PPS; Rozental, Forsell, et al., 2014) | measures procrastination by using 12 items to detect and determine dysfunctional delay. The higher the score the more likely the individual is to delay an activity or task | Baseline, WK4, WK8 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Demographics | Age, gender, ethnicity, whether they were the first person in their family to attend university, international student status, course type, year of study, and method of recruitment. | Baseline | 
| Clinical Perfectionism Questionnaire (CPQ) (Fairburn et al., 2003) | Assessment of cognitive, behavioural, and affective aspects of setting goals and striving to meet them. This scale has 12 items that assess clinical perfectionism. Items 2 and 8 are reverse-scored.The CPQ items are scored based on the individual's experiences over the past 28 days. The scale utilises a 4-point Likert scale ranging from 1 with the statement not at all to 4 with the statement all the time. Higher scores on the CPQ indicate higher levels of perfectionism. | Baseline, WK4, WK8 | 
| Depressive symptoms: Patient health questionnaire-8 (PHQ-8) (Kroenke et al., 2008) | This assessment measures depressive symptoms. The questionnaire asks how often participants have been bothered or felt affected by eight possible issues or symptoms over the past 2 weeks (e.g., feeling down, depressed, or hopeless,. The scale consists of eight of the nine criteria to determine depression. A score on the PHQ-8 ≥10 represents clinically significant depression. | Baseline, WK4, WK8 | 
| Anxiety symptoms: General Anxiety Disorder Scale (GAD-7) (Spitzer et al., 2006) | This scale is used to assess anxiety using 7 items relating to worry symptoms in the last 2 weeks. The scores on the scale range from 0 to 21. There are cut off points to indicate different anxiety levels. The scores of 5,10 and 15 show the thresholds for mild anxiety, moderate anxiety, and severe anxiety. participants have been bothered or felt affected by eight possible issues or symptoms over the past 2 weeks (e.g., feeling down, depressed, or hopeless,. The scale consists of eight of the nine criteria to determine depression. A score on the PHQ-8 ≥10 represents clinically significant depression. | Baseline, WK4, WK8 | 
| Impulsivity: Short form Barratt Impulsiveness Scale (Spinella 2009) | Assessment of 15 items for impulsivity. The scale focuses on non planning, motor impulsivity, and attention impulsivity. Higher scores are indicative of more impulsivity. | Baseline, WK4, WK8 | 
| International physical activity questionnaire short form (Lee et al., 2011 | The questionnaire consists of 9 items and it asks participants about their physical activity in the last 7 days before completing the form. It explores how often participants engaged with physical activity ranging at four levels: vigorous-intensity, moderate-intensity, walking, and sitting. | Baseline, WK4, WK8 | 
| Behavioural activation for depression scale (BATDS-SF) (Manos et al., 2011) | Assessment of experienced pleasure from daily activities over the past week. It consists of 9 items on 7 point scales from 0 to 6. 0 being not at all to 6 completely. | Baseline, WK4, WK8 | 
| Intervention acceptability and appropriateness using the Intervention Appropriateness Measure (IAM), acceptability of Interventions Measure (AIM) and feasibility of intervention measure | This scale is used to measure how appropriate the intervention will be on the participants. This assessment uses 4 item measures which focus on how likely it is that the implementation of the intervention will be successful on the participants. | WK4, WK8 | 
| Usage data from intervention platform (e.g., time spend on modules, completion of worksheets) | Assessing how far and how much of each module was completed based on time spent and whether worksheets were completed. | Baseline to WK8 |
