Feedback from recently returned veterans on an anonymous web-based brief alcohol intervention.

BACKGROUND: Veterans of Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) are at increased risk for alcohol misuse, and innovative methods are needed to improve their access to alcohol screening and brief interventions (SBI). This study adapted an electronic SBI (e-SBI) website shown to be efficacious in college students for OEF/OIF veterans and reported findings from interviews with OEF/OIF veterans about their impressions of the e-SBI.
METHODS: Outpatient veterans of OEF/OIF who drank ≥3 days in the past week were recruited from a US Department of Veterans Affairs (VA) Deployment Health Clinic waiting room. Veterans privately pretested the anonymous e-SBI then completed individual semistructured audio-recorded interviews. Their responses were analyzed using template analysis to explore domains identified a priori as well as emergent domains.
RESULTS: During interviews, all nine OEF/OIF veterans (1 woman and 8 men) indicated they had received feedback for risky alcohol consumption. Participants generally liked the standard-drinks image, alcohol-related caloric and monetary feedback, and the website's brevity and anonymity (a priori domains). They also experienced challenges with portions of the e-SBI assessment and viewed feedback regarding alcohol risk and normative drinking as problematic, but described potential benefits derived from the e-SBI (emergent domains). The most appealing e-SBIs would ensure anonymity and provide personalized transparent feedback about alcohol-related risk, consideration of the context for drinking, strategies to reduce drinking, and additional resources for veterans with more severe alcohol misuse.
CONCLUSIONS: Results of this qualitative exploratory study suggest e-SBI may be an acceptable strategy for increasing OEF/OIF veteran access to evidenced-based alcohol SBI.

Introduction

Individuals deployed for combat in Iraq and Afghanistan for Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF), a group now numbering more than 2.2 million [1], are at high risk for alcohol misuse [2], and those with combat exposure are especially at risk for new onset of alcohol misuse and alcohol-related problems [2-4]. The prevalence of alcohol misuse among OEF/OIF veterans (22–40%) is highest among veterans treated in the Veterans Health Administration (VA) [5-7]. Yet, OEF/OIF veterans are cautious about seeking care for substance use and mental-health concerns [2,8,9].

Evidence-based alcohol screening and brief alcohol intervention (SBI) can reduce drinking [10]. The VA implemented routine clinical alcohol screening [11] and brief intervention (BI) after implementation of a performance measure and electronic decision support [12]. However, false-negative screens [13], receipt of care outside the VA, and stigma-related concerns [8,14] prevent many OEF/OIF veterans from accessing alcohol-related care. Innovative approaches are needed to increase the reach of SBI for OEF/OIF veterans.

Web-based alcohol screening and BI (e-SBI) can increase access to evidenced-based care for alcohol misuse by providing anonymous personalized interventions to large numbers of people at low cost [15-17] and can increase disclosure of alcohol use[18]. An anonymous web-based e-SBI program may be particularly well-suited for young, employed, and web-savvy OEF/OIF veterans [7,19] who have a preference for online mental-health information and may be more comfortable with a private e-SBI due to the stigmatization of alcohol misuse [19-21].

Electronically delivered SBIs vary widely in length, therapeutic intensity, design, and populations targeted, and systematic reviews have arrived at different conclusions about their overall efficacy [22-26]. A recent meta-analysis of 19 randomized control trials found e-SBI resulted in a similar reduction in weekly alcohol consumption as face-to-face brief intervention (BI) [27]. A brief (<10 minute) single-session e-SBI known as THRIVE has proven efficacious in New Zealand and Australian college students [28,29] and includes alcohol-use assessment and feedback based on the 10-item Alcohol Use Disorders Identification Test (AUDIT) [30]. THRIVE’s potential causal mechanism has been described as motivational enhancement through the provision of self-focused and normative feedback [31,32].

Because of THRIVE’s proven efficacy in young adults, the current study adapted its web interface and programming logic [29,33] for use among OEF/OIF veterans based on feedback from VA and non-VA alcohol experts and local and national OEF/OIF veteran experts who were interviewed after reviewing the THRIVE website (Table 1). The resulting e-SBI (http://www.DrinkCheck.org) used a briefer alcohol screen, the 3-item AUDIT-C (consumption questions only) questionnaire [11,34] because of the availability of normative AUDIT-C data from VA outpatients. DrinkCheck was equally as brief (<10 minutes) and included 12 web pages (Table 1). This qualitative study used semistructured interviews to explore a small sample of OEF/OIF veteran patients’ experiences with, and opinions about, DrinkCheck.

Methods

Adapted e-SBI

Changes made to THRIVE in developing DrinkCheck are outlined in Table 1. In brief, DrinkCheck assessed frequency and quantity of alcohol use (Figure 1A) and assigned participant alcohol risk to one of four categories based on AUDIT-C scores, estimated weekly alcohol consumption, and the greatest number of drinks per day or occasion. Participants were provided brief feedback on their level of risk (Figure 1B), and, if participants reported heavy episodic drinking (≥5 drinks per occasion for men and ≥4 drinks per occasion for women), they received normative feedback that compared their drinking to that of age- and gender-matched VA outpatients based on AUDIT-C data from outpatient surveys (2004–2007) [35]. Additional personalized feedback was offered as well (Table 1).

Participant selection

A convenience sample of patients attending the Deployment Health Clinic (DHC) of a single large urban VA medical center was approached in the waiting room and asked to participate in a study of a short anonymous web-based alcohol-use assessment and feedback program for returning veterans. Interested patients completed a brief eligibility survey and were eligible if they were OEF/OIF veterans and reported drinking alcohol on three or more days in the past week. Patients were excluded if they were pregnant or demonstrated major cognitive impairments on the Mini-Cog assessment instrument [36]. Eligible patients were offered US $20 in compensation for pretesting the DrinkCheck and completing interviews. The VA “rapid-response” research program that funded this study did not allow studies of 10 or more veterans; a larger sample would have required review by the US Office of Management and Budget and delayed results [37,38]. Therefore, enrollment was limited to nine subjects. Patients provided verbal consent, and the study received approval and waivers of written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization from the VA Puget Sound Health Care System Institutional Review Board. To prevent participant identification due to the small sample size and ensure participant confidence in their privacy, minimal demographic information was collected.

Data collection

Participants completed DrinkCheck alone in a private clinic room on a freestanding laptop that was not connected to the internet. Subsequently, participant responses were cleared so that the interviewer was blinded to responses unless volunteered. Participants were then interviewed by the lead author using a semistructured interview that asked about their experience completing the e-SBI program (Appendix A). Participants were asked to review and provide their opinions on each page of DrinkCheck, as well as their thoughts on how to make it more appealing to other returning veterans. Initial questions included, “How did you feel about the feedback you received?” and then for each page, “What are your impressions of this page?” followed by additional open-ended questions to explore responses and any concerns they raised. Interviews were digitally audio-recorded, transcribed, and reviewed for accuracy.

Data analysis

Two of the coinvestigators, a clinical psychologist and a nonclinician researcher, used template analysis [39,40] to initially code the transcribed interviews. Template analysis is a qualitative technique that lies between grounded theory and content analysis and begins with an inventory of a priori domains expected to be strongly relevant. For this study, a priori domains reflected the anonymity and individual features of DrinkCheck [33,41]. Emergent domains were those that emerged from the data as coding proceeded (e.g., those not identified a priori) and were extensively and iteratively reviewed with investigators. A final coding template was arrived at by consensus including both a priori and emergent domains.

Results

Participants

Thirty-eight patients were approached in the waiting room of the DHC, and 36 (95%) agreed to participate. Of the 36, 17 (47%) were eligible OEF/OIF veterans who reported consuming alcohol on three or more days in the previous week. Eight of 17 (47%) eligible patients either did not have time to participate following their appointment or did not return from the clinic, which was on a different floor than the waiting room. One female and eight male OEF/OIF veterans representing multiple military service branches (Table 2) and a broad age range (23–55 years; mean, 33 years) completed the study. During the interview, each participant volunteered that their drinking was categorized as risky, high-risk, or very high-risk by the e-SBI feedback and that they had also received feedback on heavy episodic drinking. To avoid identification of the one female participant, participants are hereafter referred to as male.

A priori domains

Participants provided useful feedback on six a priori domains regarding features of DrinkCheck (Table 3). Overall, they were pleased with its length, standard drinks image, and feedback on alcohol calories and money spent on alcohol. They were not surprised by the feedback on blood alcohol concentration and legal driving limits. They also reported the anonymity of DrinkCheck was important for obtaining truthful responses.

Domains and Selected Quotes from Interviews with Nine Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF) Veterans

A prioridomains	Quotes
The e-SBI program was considered short and succinct	“I mean, it’s good ‘cause it’s not too long, and it’s not too short… it has good information and is something, you know, a soldier or anybody can, could, actually take.” (Veteran C)
	“It was short, simple, to the point, which is always easiest with military people - very impatient, just get to the point.” (Veteran G)
The standard drinks image was considered helpful	“When I saw these pictures on the side with the equal amounts of drinks to a bottle or a pint, it was kind of interesting ‘cause I didn’t really know that… made me think of, actually, how much I really drink.” (Veteran C)
	“That is actually very informative ‘cause a lot of people don’t know exactly, I think, how much one drink is. Depending on what bar you go to or how many you drink at home, people can distinguish one drink as an entire glass of whiskey or… as a 24-ounce can of beer.” (Veteran E)
Participants appreciated feedback on estimated alcohol calories consumed and hours of exercise	“I was appalled at how much calories I had consumed…it was just like ‘Oh, geez.’” (Veteran G)
	“It was cool. I was like ‘Whoa, it shows, like, how much…food and stuff, like, it could be equaled out to’…I’d rather have a cheeseburger, obviously.” (Veteran I)
Feedback on estimated money spent on alcohol in the past year was also appreciated	“I said ‘Thank goodness I don’t go to the bar.’ But, wow…mine was, like, $700. I said ‘I could have bought a TV or something.’ You know…you could buy a used car… I liked that…I wouldn’t change that. That’s good.” (Veteran D)
	“That’s a lot of money…right now I’m unemployed so it’s like do I really need to be drinking that much?” (Veteran G)
	“It’s like ‘Dang. I don’t want to spend that much on that, that stuff.’ You know? Like, I could be spending that on other things that, you know, I won’t be getting a headache in the morning.” (Veteran I)
Feedback on the highest blood alcohol content and legal driving limit was obvious, but some noted it was worth keeping	“When I drank that much I was drunk, I remember. That’s pretty obvious too, I’d have to say. I didn’t plan on driving ‘cause I knew I was drunk…I think that was a good one.” (Veteran F)
	“The point is well taken. But, I knew that anyway. Not saying that it shouldn’t be in here. I’m just saying that ‘Well, yeah, I had 12 drinks in four hours. Of course I was trashed.’…And is it illegal to drive? Bet your butt it’s illegal to drive…I think it’s good to be in there.” (Veteran H)
The anonymity of the eSBI website was noted as a benefit	“I think if it was private and the information was solely provided to the individual…you might have a better impact on that individual…for them to be more open and truthful about themselves.” (Veteran D)
	“I think on NKO [Navy Knowledge Online]…if they had asked me specific things like that and it would have gone in electronic record, I would have definitely not answered honestly….so, knowing that it’s anonymous helps people answer honestly, and knowing that it’s not going to go basically bite them in the ass at some point” (Veteran G)

Emergent domains

Seven emergent domains were identified from participant interviews and are described below.

Questions about alcohol consumption “in the past year” were difficult to answer for recently returned veterans

Veterans reported alcohol was scarce and was generally prohibited during deployment. As a result, most participants said they did not drink alcohol while serving overseas. However, the AUDIT-C questions assessed typical and heavy-episodic drinking in the past year and were therefore challenging for participants who had recently returned:

"[Veteran C]: I guess the timing on it… it plays a major factor, because at some points in the year, you actually don’t even drink."

Participants were aware that their drinking when not deployed was probably most pertinent to the assessment, yet many averaged their consumption over the entire year:

"[Veteran E]: But over the past year people’s situations will be different.... I was just on deployment, so for six months I didn’t have anything… and then this past six months, it’s like, “Well, OK, now I’m getting back into the swing of things.” And so, they average it out over that, that entire time."

Questions about health and relationship concerns were confusing to veterans

DrinkCheck included questions about the frequency of health and relationship concerns in the past four weeks. Despite an introductory statement, “These questions ask about symptoms and concerns veterans may have that can be influenced by drinking,” veterans did not understand why they were being asked about such concerns:

"[Veteran H]: So, the question is, okay, “How often are you bothered by the following?” Well, why do you care?… What is it you’re trying to get at when you ask me these questions?"

Additionally, participants wondered how and in which causal direction the concerns were associated with alcohol:

"[Veteran B]: Some of these I also look as being effect, not so much a cause.... “Managing pain”—don’t really see it so much as an effect as a cause. “Trouble falling asleep, staying asleep or nightmares” can actually go both sides."

"[Veteran F]: Those were all pretty good questions that apply to drinking. I answered them honestly, but… some of those you can have whether you’re drinking or not."

Veterans wanted transparent nonjudgmental feedback and practical advice

The alcohol-risk feedback posed several problems for participants. First, they did not understand how or why they were assigned to their particular risk category:

"[Veteran B]: It doesn’t show me what it is that I do that put me in that risk category versus the next one down or the one below that.... What makes me very high risk? You know, outline it [referring to risk categories]. What about me makes me so much higher risk than the person in this one?"

"[Veteran D]: We didn’t go into depth about the category you’re putting me in….what do I do? Why does it matter?… You know, am I going to die that week because I had 15 drinks?"

Overall, participants wanted an explanation of what specifically about their drinking was risky as well as risk-reduction strategies tailored to their alcohol consumption and problems. Veteran D suggested adding more detail to the risk categories (e.g., “probably needs no assistance,” “should seek assistance”), as he wanted to know what he could do to reduce his risk:

"Okay, so, yeah, I drink too much. I’ve thrown up. I’ve had a hangover. That’s risky.... And, I’m aware of that. [It] doesn’t tell me maybe I should do something different. Doesn’t motivate me to."

Veteran F explained how greater personalization could encourage a decrease in drinking:

"[Referring to risk assignment]: If you saw that and were thinking about what could make my relationship better, and it says ‘less drinking,’ you’d be like, “Oh, well, there’s an eye-opener.” …[I]f it said something personal that could really only apply to you, by taking this, then I think people would think twice about going and drinking a lot."

Further, for some veterans, the risk feedback implied a judgment about them and their drinking:

"[Veteran B]: [People] use this and it just turns back and says, “Yeah, you’re drinking too much.” And, all of a sudden, what has that done? Just one more person accusing them."

Although the risk categories were intended to highlight the continuum of alcohol-related risk, some veterans viewed alcohol risk as “all or nothing”:

"[Veteran I]: If society says that you drink too much, then you’re deemed an alcoholic or a drunk. And, you know, it’s like there’s no real safe gray area in there that you could play with all that much."

Veterans felt the context for their drinking should be considered when assessing risk

Participants did not typically consider their alcohol consumption as risky or inappropriate for the occasion and thought the context for drinking and whether problems were present, not just the level of consumption, were relevant to the assessment of risk:

"[Veteran A]: Maybe it‘s just me, but maybe the wording ‘risky drinking.’ You know, you’re doing risky drinking. Well, it doesn’t seem risky when I’m doing it. (Laughter) I’m not going to hurt anybody. I’m not going to do anything wrong."

The context for risky drinking was perceived as particularly relevant if drinking was associated with a festive occasion:

"[Veteran E]: [It’s been] my birthday, then Christmas, then New Year’s, all in two weeks. And, I’m always responsible with my drinking. I always make sure that if I, I’ve had more than three drinks total in the night, I always take it easy at least an hour before I drive. Make sure I’m calmed down."

Context was also considered particularly relevant for a difficult occasion:

"[Veteran G]: For me, once a month going out and doing 13 drinks over 9 hours. Like, that’s not much compared to the two or three drinks I’ll have once or twice a week… Usually when I do have those binge nights, there’s a very specific reason I go out and drink like that, whether I’m celebrating… but this last time it was—I didn’t get a job, and I was very upset, and I thought I was gonna get it and it’s been two months, and I’m just like, uh. So, there was a reason; it was, “I’m just gonna go out and do this, and get all my frustrations out.”"

Individual differences were also important for explaining heavy episodic drinking:

"[Veteran F, referring to risk feedback]: That didn’t scare me into drinking any less ‘cause, honestly, I think people’s recommended limits aren’t everybody’s. ‘Cause people are, like, “Oh, don’t drink any more than a six pack.” And, that’s pretty much what I like. And, I don’t really seem to be having a problem with it."

Veterans dismissed the normative feedback because it lacked credibility

All participants voluntarily reported receiving normative feedback for heavy episodic drinking, which attempted to highlight the incongruence between participants’ perception of “normal” drinking and actual norms. However, they had difficulty accepting veteran outpatients as an appropriate comparison group given differences in experiences among veterans:

"[Veteran E]: If you’re just taking into account all VA patients 30 to 39 over the entire country, doesn’t necessarily mean that they spent as much time on deployment, doesn’t mean that they went to the same places that we did, or that I have."

Moreover, a few were skeptical of the comparison group data, believing it underrepresented OEF/OIF veterans’ drinking, and that other OEF/OIF veterans would think so as well. Participants felt they knew what their peers were consuming, and it was as much or more than their own consumption:

"[Veteran H]: This one here is one of the ones that I thought, “Oh, bull.” “I drink more drinks in a single day than 99 percent of male VA patients my age.” I don’t believe that for a second, okay?… I mean, I know a lot of guys, a lot of Vets… you know, and, they drink just as much as I do, if not more."

Veterans spontaneously offered unsolicited stories/anecdotes about drinking

Although the interview was designed to elicit participant opinions about DrinkCheck and not private information about themselves, every participant volunteered personal details about their experience with alcohol. Personal stories were interwoven throughout the interviews and were often the byproduct of a participant’s review of a specific e-SBI feature. In reference to “managing pain” listed among the health concerns, Veteran F shared this:

"I’ll have to say, I do drink sometimes cause of that. Like, I separated my shoulder last week, and I can’t just go to the doctors anytime and pick up medication. And, so, a six pack helps. And, a six pack and a hot tub does a pretty good job on that one. So, I have to say I do drink for that sometimes."

Veterans also spoke openly about their experience with alcohol without responding to a specific e-SBI feature. In explaining his tolerance for alcohol, Veteran E offered:

"My family has a history of alcoholism, and I remember being seven years old and having to drive my dad home drunk from the bar. At seven. It’s kind of screwy. Since then, my father has severely cut back on his drinking. He’s 74 now. He’ll go out, you know, maybe once, twice, a week.... He’ll go out with his buddy, and they’ll have six, seven beers… another night during the week, they’ll do the same thing."

Veterans reported benefits of completing DrinkCheck

Despite elicited criticism regarding specific e-SBI features, all nine OEF/OIF veterans found the program somewhat helpful in encouraging consideration of their drinking. Specifically, some veterans appreciated being provided the recommended drinking limits [42] and felt the information succinctly summed up what they needed to know to avoid unsafe consumption:

"[Veteran C]: I’ve seen a whole bunch of, like, drinking videos and stuff like that, and they really don’t say, you know, what the actual limit is for, you know, not really harming yourself."

Further, despite some doubts and dissatisfaction with the feedback, a few OEF/OIF veterans expressed interest in changing their drinking:

"[Veteran A]: You know, it definitely makes me reflect. I think, “Well, hold on a second, you know, it would be better not to drink quite so much at those times.”"

Some were surprised by their consumption and suggested other veterans using the program might be as well:

"[Veteran G referring to normative feedback]: I liked this page, because I was like “Oh my god” (laughs). Cause I just didn’t realize… putting it on the most that you drank in one night, I was like, “Wow, remind me not to do that very often.” I’ll think about that a lot more."

Lastly, several participants indicated interest in assistance with their drinking beyond what DrinkCheck had to offer:

"[Veteran D]: I don’t want to stop drinking alcohol. And I think I can safely have a drink or two, but maybe I should look at some strategies. Not for quitting, ‘cause I saw [the “Strategies for Cutting Down” link on the Resource page] and I thought, “That’s it.”"

In particular, Veteran B, who described a family history of problem drinking and experience with Alcoholics Anonymous, suggested offering additional resources:

"[Veteran B]: Maybe resource links if the VA has resources… “These are healthy drinking habits. These are resources that are available to you to help you get there.”…[I]f it takes more of a, a corrective approach, giving them steps, giving them resources, giving them options… those types of things are going to cause people to want to come back, to want to re-evaluate themselves, to continue to use the system."

Discussion

This qualitative observational study explored the acceptability of an efficacious web-based Australian e-SBI for college students [29] adapted for use with OEF/OIF veteran outpatients. Although each of the nine OEF/OIF veteran participants found different features of DrinkCheck useful, all felt it was helpful in promoting consideration of their own drinking. Findings that emerged from interviews included participant difficulty answering past-year consumption questions due to changes in drinking during deployment, doubts about the representativeness of the normative feedback from VA outpatients, a desire for more transparent personalized feedback on what made their reported drinking risky, and personalized risk-reduction strategies. During the interview, all participants spontaneously volunteered personal information about their drinking, and several expressed interest in changing their drinking and/or additional resources for reducing their consumption.

Some findings from this study are specific to development of e-SBIs for OEF/OIF veterans. Assessment of alcohol consumption should allow for possible recent changes in drinking. Some participants reported averaging their drinking over the entire year, including time when they were not drinking due to deployment. To avoid underestimation of recent alcohol use, future e-SBI adaptations for returned veterans may want to account for deployment periods by assessing recent drinking or using the AUDIT-C questions without a timeframe [43]. Additionally, OEF/OIF veterans may be more willing to reflect on their own drinking if normative feedback is based on comparable measures from other OEF/OIF veterans [44]. Normative feedback was based on the greatest number of drinks on one occasion from age- and gender-matched AUDIT-C data from VA outpatient surveys, while e-SBI participants were explicitly asked the greatest number of drinks in the past four weeks. This incongruence may have contributed to participant skepticism. Lastly, an anonymous e-SBI may be an effective tool for ensuring that OEF/OIF veterans receive feedback that is reflective of their actual drinking. Many participants felt they would be more likely to accurately report their alcohol use to an anonymous web-based program than in-person, consistent with previous reports from active-duty Marines [20]. Military personnel can lose their jobs for alcohol-related misconduct or failure to attend or respond to alcohol treatment [45], and a recent change to regulations [46] that allows for sharing of previously protected medical records between the VA and the US Department of Defense is likely to augment concerns about stigma and job-related impact [2,8].

Some findings from this study of nine OEF/OIF veterans may be applicable to the development of e-SBIs and possibly clinically delivered BIs for other populations. Results suggest that feedback needs to be transparent, as participants were nearly universal in their wish to know how they were assigned to their particular risk category. Tailored personal feedback could include a summary of a participant’s drinking and whether, and the extent to which, weekly or daily limits were exceeded. Electronically delivered SBIs could also be used to educate patients about the risks of heavy episodic drinking. Several participants felt their heavy drinking episodes were not problematic if they were not taking physical risks (e.g., driving) or experiencing adverse alcohol-related consequences. The e-SBI could inform such patients of the association of heavy episodic drinking with cognitive deficits [47] and development of addiction to alcohol [48,49].

Finally, this study suggests that following e-SBI with an opportunity for participants to debrief could serve as a method to engage veterans around their drinking. Although all nine OEF/OIF veterans easily engaged in a detailed candid discussion of the website as anticipated, it was not anticipated that participants would spontaneously volunteer personal information about their own drinking. This finding suggests that providing returning veterans anonymous opportunities to complete and then discuss their alcohol-use assessment and feedback may be a useful method for engaging them in conversations about their drinking.

Results of this study also suggest areas for further research. Normative feedback is a common component of e-SBI and, although no systematic review of the effectiveness of normative feedback has been conducted, it has reduced drinking in college students [44] and was a key component of THRIVE [29]. However, it remains unknown whether normative feedback has efficacy in general adult or clinical populations. Additionally, little is known about the usefulness of e-SBI for highest risk patients, including individuals with alcohol dependence [20,50]. Results from this study suggest that e-SBI should address the needs of these patients. Further, given the scarcity of qualitative research on patient experiences of clinically delivered BI, results also suggest the potential value of similar research on BI delivered clinically. Lastly, this research underscores the value of eliciting qualitative input on e-SBI from the target population.

This study has important limitations, the greatest being that enrollment was limited to a convenience sample of nine OEF/OIF veterans, all of whom were outpatients at a single medical center. Therefore, analyses were limited to descriptive exploration of responses, and it is unlikely that saturation of themes was reached. Further, the small sample was likely inadequate for observing the variation that exists among the general population of OEF/OIF veterans. It is possible that different findings may have emerged had purposive sampling been used to identify patients from different veteran subgroups, additional sites and regions, and veterans who were not receiving care from the VA. Results from this study may best be interpreted as a useful starting point for informing future development of e-SBI for OEF/OIF and other veterans.

Conclusions

To summarize, this qualitative exploratory study of nine OEF/OIF veterans found that e-SBI was useful in promoting consideration of their own drinking. Such interventions may be most appealing to OEF/OIF veterans if they ensured anonymity, provided personalized transparent feedback about alcohol-related risk, consider the context for drinking, and provide strategies to reduce drinking and additional resources for veterans with more severe alcohol misuse. Results also highlight the importance of educating patients about the risks associated with heavy episodic drinking. Offering an e-SBI program that is relevant and attractive to OEF/OIF veterans could be an effective strategy for increasing their access to evidenced-based care for alcohol misuse.
