About this trial
This observational study investigates an Internet-delivered Cognitive Behaviour Therapy (ICBT) intervention for alcohol misuse, called the Alcohol Change Course Enhanced (ACCE). The intervention will be offered through the Online Therapy Unit, which is a routine care ICBT clinic. The primary objective of the study is to examine whether engagement in adaptive actions measured by the Things You Do Questionnaire (TYDQ), including healthy thinking, meaningful activities, social connections, healthy habits and goal setting - increase during ICBT for alcohol misuse. Using data collected during routine care, the relationship between adaptive actions and alcohol use will be investigated, and specifically explore if the frequency of adaptive actions increases as alcohol use reduces during the intervention.

Treatments tested in this trial
Alcohol Change Course Enhanced
BehavioralThe Alcohol Change Course Enhanced is an adaptation of the Alcohol Change Course, originally developed and evaluated in Switzerland. The Course is a six-lesson ICBT intervention delivered over eight weeks to individuals who self-report alcohol misuse. Due to therapist registration and availability, eligible clients residing in Saskatchewan will be offered the option of receiving therapist assistance (or not) alongside the Course, while clients from other Canadian provinces will not receive therapist support. In addition to the monitoring of weekly measures available to all clients, those receiving therapist support will receive weekly secure messaging from their assigned therapist for eight weeks. Therapists will spend approximately 15 minutes per week/per client receiving therapist support. Phone calls will be used in the event that there is a significant clinical issue requiring therapist attention that cannot be addressed over messaging (e.g., sudden increase in symptoms).
Treatment groups
Trial outcomes
Primary outcomes
Changes in Alcohol Consumption
Measured with Total Number of Drinks in the Last Week. Clients report the number of standard drinks consumed on each of the preceding 7 days, with numeric values. Two variables are derived for each time point (screening, mid-treatment, post-treatment, and follow-up): 1) total weekly consumption, calculated as the sum of standard drinks during the preceding 7 days, and 2) number of heavy drinking days (HDDs) in the past week. HDDs are defined as days on which consumption exceeds gender-specific thresholds defined by the National Institute on Alcohol Abuse and Alcoholism (i.e., 4 or more standard drinks for women, 5 or more for men).
Changes in Adaptive Actions
Measured using the Things You Do Questionnaire-15 item (TYDQ-15), which consists of 15 items related to 5 factors: healthy thinking, meaningful activities, goals and plans, healthy habits, and social connections on a 5-point Likert scale ranging from 0-4. Scores are summed into subscale scores ranging from 0 to 12, and a total score ranging from 0 to 60, with higher scores indicating greater engagement in adaptive actions. Clients self-report how often they engaged in each activity in the last week.
Secondary outcomes
Changes in Alcohol Craving
Measured using the Penn Alcohol Cravings Scale. 5 items are measured on a 7-point Likert scale ranging from 0-6. Scores are summed into a total score ranging from 0 to 30. Higher scores indicate greater alcohol cravings.
Change in Alcohol Use Disorder Identification Test Scores
The Alcohol Use Disorder Identification Test (AUDIT) is a10-item screening tool to assess for problematic alcohol use. The first eight items are measured on a 5-point Likert scale ranging from 0-4, while the last two items are measured on a 3-point Likert scale ranging from 0-4. 10 items are summed to produce a total score ranging from 0 to 40, with higher scores indicating more severe alcohol use problems.
Changes in Depression
Measured using the Patient Health Questionnaire 9-item (PHQ-9). 9 items are measured on a 4-point Likert scale ranging from 0-3. Scores are summed for a total score ranging from 0 to 27. Higher scores indicate more severe depressive symptoms.
Changes in Anxiety
Measured using the Generalized Anxiety Disorder 7-item (GAD-7). 7 items are measured on a 4-point Likert scale ranging from 0-3. Scores are summed to create a total score ranging from 0 to 21, with higher scores indicating more severe symptoms.
Other outcomes
Background Information
Background information including demographic questions will be collected at screening for descriptive purposes. No scores are calculated.
Drug Use
The Drug Use Disorder Identification Test-Concise (DUDIT-C) is a 4-item measure used to assess problematic drug use. Items are measured on a 5-point Likert scale ranging from 0-4, with total scores ranging from 0-16. Higher scores indicate more severe drug use problem.
Motivation for Change
Measure of clients' motivation for changing their alcohol use. Clients self-report the importance of changing their alcohol use, their confidence in their ability to change their alcohol use, and their readiness to change their alcohol use using 3 items. Each item is rated from 1-10, and scores are summed to produce a total score ranging from 3-30, with higher scores indicating higher motivation.
Changes in Alcohol Consumption in the Previous Week
Clients self-report how many total standard drinks they consumed in the previous week and the number of days they consumed alcohol using two questions. Standard drinks are defined as: one 12 oz (341 mL) can or bottle of 5% beer, cider, or cooler; one 4.5 oz (142 mL) glass of 12% wine; or one 1.3-1.5 oz (40-45 mL) shot of 40% distilled spirits. This measure is used by clinicians to assess alcohol consumption on weeks when the primary alcohol measures are not administered.
