Brief Alcohol E-Interventions Study
14. juni 2019 opdateret af: Emily Grekin, Wayne State University
Optimizing E-interventions for Alcohol Use: Do Common Factors Apply?
The project seeks to develop an effective computer-delivered brief intervention to reduce alcohol use using the Multiphase Optimization Strategy (MOST).
Sixteen different versions of the intervention will be tested with manipulation of common factors (empathy & positive regard), use of a voice, and use of an animated narrator.
Participants will include 352 undergraduate students randomly assigned to one intervention condition; follow-up assessments will take place at one and 3 months.
The main outcome will be means drink per day over the past 30 day.

Detaljeret beskrivelse
The proposed project seeks to develop a maximally effective computer-delivered brief intervention (CDBI) for reducing heavy alcohol use.
To accomplish this, we will use the Multiphase Optimization Strategy (MOST), an efficient method for optimizing intervention content, beginning with factorial designs evaluating main and interaction effects of specific intervention components.
Our selection of components will be guided by: (a) Common Factors Theory, which highlights the tremendous contribution of non-specific factors, such as empathy and positive regard, to therapy outcomes, but which is of unknown relevance to CDBIs; and (b) Media Equation Theory, which suggests that people automatically respond to computers in social ways, particularly when those computers replicate human characteristics.
To accomplish these goals, we will examine outcomes of computer-delivered brief interventions in which common factors (empathy & positive regard), use of a voice, and use of an animated narrator are systematically manipulated using a factorial design.
We will also systematically manipulate the presence vs. absence of motivational content in order to examine possible interactions between common factors and specific motivational techniques.
Participants will be 352 undergraduates who are randomly assigned to 1 of 16 intervention conditions.
Mean drinks per day over the past 30 days will be measured at 1 and 3-month follow-ups.
Secondary analyses will also examine past month heavy drinking days, alcohol-related consequences, and intention to reduce alcohol use.
We hypothesize that there will be significant main effects for (1) the factor consistent with Common Factors Theory (empathy and positive regard), (2) the two factors consistent with Media Equation Theory (voice and narrator), and (3) the presence of motivational content.
We further hypothesize that mean drinks/day will be lower when (1) the common factors (empathy, positive regard) are combined with a voice and/or narrator or (2) motivational content is combined with common factors and/or a voice/narrator.

Intention to Reduce Alcohol Use
Tidsramme: 1 month and 3 months after baseline
|
Participants self-report intentions to reduce drinking on the Drinking Intentions Questionnaire.
On this questionnaire, participants rate how likely they are to reduce their drinking over the next week, month, and year on a scale ranging from '0 = Not at all likely' to '5 = Extremely likely.'
Higher scores mean greater intentions to reduce drinking.
In order to obtain more stable estimates and reduce type I error, responses to the week, month and year questions were summed to create a total drinking intentions score which could range from 0 to 15.
More specifically, scores on each individual scale item (i.e.
intentions to reduce drinking over the week, month and year) could range from 0 to 5. When summed together, these items created the total score (reported here) which could range from 0 to 15.
