Brief summary

Alcohol misuse amongst youth is a significant clinical and public health problem. The Emergency Department (ED) is an important setting for the treatment of alcohol-related problems as it is often the first point of contact between youth, their families, and the healthcare system. This pilot study will assess the feasibility and acceptability of a computer-based intervention in the ED for youth with alcohol-related presentations. The investigators research team will: (1) evaluate the methodological and operational processes involved in study recruitment and intervention implementation, (2) determine recruitment and retention rates, and (3) obtain preliminary data on the difference in alcohol consumption at different time points. The clinical and health service implications of this research will be used to plan further investigations designed to improve the standard of ED care among youth aged 12 to 16 with alcohol-related presentations. This research will also help optimize the planning and development of a full-scale randomized controlled clinical trial of a computer-based intervention designed to reduce higher-risk alcohol consumption and alcohol-related health and social problems in this target population.

Interventions

BEHAVIORALComputer-based PAF

This intervention includes standard medical care followed by receipt of computer-based Personalized Assessment Feedback (PAF). PAF is a type of brief intervention that targets norm misperceptions, for example summarizing a person's drinking in comparison to the average male or female in the general population. Theoretically, such normative feedback corrects norm misperceptions and motivates drinkers to re-evaluate their consumption patterns.

BEHAVIORALComputer-based Sham

This intervention includes standard medical care followed by receipt of a computer-based sham. The sham is similar in format and duration as the computer-based Personalized Assessment Feedback but will engage youth in nutrition and exercise-related questions.

Inclusion criteria

Study Inclusion Criteria: * Youth aged 12 to 17 years who present to the Emergency Department (ED) with an alcohol-related problem. * Medically stable Alcohol involvement will be determined by youth self-report of drinking alcohol prior to event necessitating a visit to the ED and/or a positive Blood Alcohol Content (BAC). Study

Exclusion criteria

* Youth who require hospital admission * Youth whose ED presentation is linked to drugs aside from alcohol * Youth who report other drug use within the last 24 hours prior to ED presentation * Youth who do not speak or understand English * Youth who are currently enrolled in a treatment program for alcohol use * Youth who are accompanied by a non-guardianship adult but are not considered Mature Minors * Youth who do not have the capacity to give informed consent as determined by their attending ED physician * Youth do not have regular access to their own telephone

Design outcomes

Primary

Measure	Time frame	Description
Change in Youth Alcohol Use	baseline, 1 and 3 months post-intervention	AUDIT-C (Alcohol Use Disorders Identification Test Consumption subscale): 1 item regarding frequency of alcohol consumption, 1 item regarding the amount of alcohol consumption, and 1 item regarding the frequency of binge drinking. Scores range from 0 to 12 with higher scores reflecting more consumption. The change in alcohol use report below reflects the change in AUDIT-C scores with negative values indicating a reduction in score and positive values indicating an increase in score.

Secondary

Measure	Time frame	Description
Retention Rates	1 and 3 months post-intervention	—
Knowledge of Treatment Allocation	post-intervention (day 1)	—
PAF Feasibility and Acceptability	youth: post-intervention (day 1)	The acceptability of the Personalized Assessment Feedback (PAF) intervention will be assessed by youth post-intervention (only youth allocated to the PAF intervention). Measure assessed acceptability (satisfaction with the intervention, perceptions of the helpfulness, credibility of the personalized assessment feedback) and feasibility (time to completion, user friendliness).
Recruitment Rate	18 months	To be calculated following active recruitment (18 months from study start date of patient enrolment). The recruitment rate relates to recruitment into the study, and not recruitment per arm as randomization and allocation occurred after enrolment.
Receptivity to Receiving Services: Seeking Help/Treatment	Baseline	As part of CASA measure (secondary outcome measure to measure health and social services utilization) adolescents were asked two additional questions on receptivity to receiving services. The data below reflects the first question: On a scale of 1-5, where 1 is it's definitely a bad idea and 5 it's definitely a good idea, do you think that if someone you knew had an alcohol use problem they should get help or seek treatment?
Perceived Barriers to Services	Baseline	As part of CASA measure (secondary outcome measure to measure health and social services utilization) adolescents answered 8 additional questions on perceived barriers to services: 1) Do you have any feelings such as dislike, distrust or fear about talking with doctors, counselors or other professionals? 2) Do you have any feelings about what other people would think if you sought help? 3) Do you find there is a lack of information that affected health services sought? 4) Do you have any concerns about the amount of time it takes to get help? 5) Were the health services you sought just not readily available? 6) Did you feel you just didn't want to talk to anyone about such a sensitive problem? 7) Was there a problem with registration, setting up appointments or contacting professionals? 8) Was there a problem getting to where treatment was available?
Receptivity to Services: Doctors/Counselors Can Help	Baseline	As part of CASA measure (secondary outcome measure to measure health and social services utilization) adolescents were asked two additional questions on receptivity to receiving services. The data below reflects the second question: On a scale of 1-5, where 1 is it's definitely cannot help and 5 it definitely can help, do you think that doctors or counselors can help with alcohol use problems in general?
Change in Health Care System Utilization by Youth	Baseline	The Child and Adolescent Services Assessment (CASA) is a self-report instrument designed to assess the use of community- and hospital-based health and social services. We focused each question so that we collected service use for an alcohol use problem.

Secondary

Change in Health Care System Utilization by Youth

The Child and Adolescent Services Assessment (CASA) is a self-report instrument designed to assess the use of community- and hospital-based health and social services. We focused each question so that we collected service use for an alcohol use problem.

Time frame: 3-months post-intervention

Population: Due to the large amount of missing data (at 1-month \[52.3%\] and 3-months \[59.0%\] post-intervention) we did not assess change in utilization from baseline to 1- and 3-months post-intervention (pre-specified secondary outcome) as the results would be prone to bias.

PAF Feasibility and Acceptability

The acceptability of the Personalized Assessment Feedback (PAF) intervention will be assessed by youth post-intervention (only youth allocated to the PAF intervention). Measure assessed acceptability (satisfaction with the intervention, perceptions of the helpfulness, credibility of the personalized assessment feedback) and feasibility (time to completion, user friendliness).

Perceived Barriers to Services

As part of CASA measure (secondary outcome measure to measure health and social services utilization) adolescents answered 8 additional questions on perceived barriers to services: 1) Do you have any feelings such as dislike, distrust or fear about talking with doctors, counselors or other professionals? 2) Do you have any feelings about what other people would think if you sought help? 3) Do you find there is a lack of information that affected health services sought? 4) Do you have any concerns about the amount of time it takes to get help? 5) Were the health services you sought just not readily available? 6) Did you feel you just didn't want to talk to anyone about such a sensitive problem? 7) Was there a problem with registration, setting up appointments or contacting professionals? 8) Was there a problem getting to where treatment was available?

Receptivity to Receiving Services: Seeking Help/Treatment

As part of CASA measure (secondary outcome measure to measure health and social services utilization) adolescents were asked two additional questions on receptivity to receiving services. The data below reflects the first question: On a scale of 1-5, where 1 is it's definitely a bad idea and 5 it's definitely a good idea, do you think that if someone you knew had an alcohol use problem they should get help or seek treatment?

Secondary

Recruitment Rate

To be calculated following active recruitment (18 months from study start date of patient enrolment). The recruitment rate relates to recruitment into the study, and not recruitment per arm as randomization and allocation occurred after enrolment.

Time frame: 18 months

Population: The recruitment rate was calculated as the number of enrolled participants (n=44) divided by the number of eligible participants (n=117).

Arm	Measure	Category	Value (COUNT_OF_PARTICIPANTS)
Standard Medical Care Followed by Computer-based PAF	Recruitment Rate	Number not recruited	73 Participants
Standard Medical Care Followed by Computer-based PAF	Recruitment Rate	Number recruited	44 Participants

Secondary

Retention Rates

Time frame: 1 and 3 months post-intervention

Population: We were interested in the overall study retention rates at 1- and 3-months post-intervention, and not retention rates per arm, as the purpose of calculating the rates was to assess the feasibility of a follow-up period in a definitive randomized controlled trial.

Arm	Measure	Group	Value (COUNT_OF_PARTICIPANTS)
Standard Medical Care Followed by Computer-based PAF	Retention Rates	1 month retention	21 Participants
Standard Medical Care Followed by Computer-based PAF	Retention Rates	3 month retention	18 Participants
