Abstract
Introduction
In its 2001 report, Crossing the Quality Chasm, the Institute of Medicine specifically emphasized that the Internet and other information technologies should be used to augment and foster more continuous and timely health service delivery.
1
Health information technology (HIT) includes a broad range of applications used to store, retrieve, and share health information for communication and decision-making.
2
The expansion of such services offers a potentially unique opportunity to increase access to health services among traditionally underserved populations, such as individuals with substance use disorders.
3
The Veterans Health Administration (VHA), the largest integrated healthcare system in the United States, has become a leader in many aspects of HIT with the use of a comprehensive electronic medical record, an online health information portal, My HealtheVet (MHV) (
Internet- or computer-based therapies for mental health and substance use disorders are one of the fastest growing areas of HIT. Computerized psychotherapies (CPTs) are interactive, often based on cognitive-behavioral therapeutic principles, frequently delivered over the Internet, and focused on fostering behavior change for problems such as substance use, insomnia, depression, and anxiety. 6,7 They present standardized yet individualized material in rich formats and provide a high degree of fidelity to evidence-based models at the pace and in a setting chosen by the user. 8 In addition, such therapies may reduce (1) costs associated with therapist time, (2) avoidance of treatment due to stigma, and (3) impaired access due to lack of trained therapists in some locations, scheduling conflicts, and transportation barriers. 9,10 Although the subjects and formats vary among CPTs, evidence of their efficacy has been demonstrated in several systematic reviews. 11 –14
However, the magnitude of such benefits may be blunted by obstacles related to an individual's interest in CPT or access to and use of the technology used to engage in such programs, such as the hardware and Internet infrastructure, as well as the skills needed for HIT use. 15 In the general adult population, individuals who are elderly, male, less educated, or members of racial or ethnic minorities or who have low socioeconomic status have been found to be less likely to use such technology than their counterparts. 16 –19
Given that VHA and other safety-net healthcare systems serve relatively large proportions of individuals who have substance use problems as well as other long-term health and functional problems such as chronic medical disorders, severe mental illnesses, or homelessness, 20,21 such barriers may be especially relevant to the implementation of HIT services such as CPTs in these contexts. Although similar sociodemographic disparities in HIT use found in the general population are also found among VHA service users, research indicates that there is no difference in HIT use among veterans who use VHA services, veterans who do not, and their nonveteran counterparts. 22 –24 In addition, there is some evidence that veterans who are in mental health treatment are no less likely to use Internet or MHV than those not in mental health treatment. 24 However, there is little information on the use of or interest in CPT among veterans with substance use disorders or on whether their current level of technology use affects this interest.
As VHA continues to develop CPT programs in preparation for their implementation and to expand its use of HIT in general, 25 there is a need to evaluate interest in such services and barriers among potential users. The current study surveyed interest in CPT and its relation to the use of information technology in a sample of VHA patients in treatment for substance use disorders. In addition, the rate of information technology use in this sample was compared with that in a national sample of veterans to determine the comparability of information technology use between veterans in substance use treatment and that of the general veteran population. Hypotheses were that interest in CPT would be low and associated with lower information technology use and selected barriers to use among veterans with substance use disorders compared with a national sample of veterans.
Materials and Methods
Sample
Participants were a convenience sample of 151 veterans participating in outpatient substance use treatment in the VA Connecticut Healthcare System (West Haven, CT) between November 1, 2012 and November 1, 2013 out of 1,431 veterans who had contact with the clinic during the period of recruitment. Participants obtaining outpatient methadone treatment for opioid dependence were excluded because this treatment takes place at a separate location. Research staff approached individual prospective participants in the clinic waiting room. Procedures for the anonymous, written, self-administered questionnaire were explained, and voluntary participation was elicited. Subjects received a description of the survey content and a definition of computer-based programs on a survey cover sheet. Of 191 individuals approached, 151 completed the survey (79.1% response rate). The institutional review boards of the VA Connecticut Healthcare System and the Yale University School of Medicine (New Haven, CT) approved a waiver of written informed consent for this study.
Corresponding data from participants in the substance use clinic were compared with technology use data from the 2010 National Survey of Veterans (NSV), a series of self-administered questionnaires completed by a nationally representative sample of noninstitutionalized veterans. The survey was mailed using address-based sampling to a total of 13,058 veterans, 8,710 of whom completed surveys, for a response rate of 66.7%. Sampling and weighting procedures have been described elsewhere and were applied to analyses including NSV data. 26
Measures
The clinic survey included multiple-choice questions regarding demographics as well as substance use and psychiatric diagnoses. Information technology use questions addressed current Internet and e-mail use for general as well as health-related purposes, as well as equipment used to access the Internet. Current Internet and/or e-mail use was measured by two dichotomous questions in addition to multiple-choice questions addressing the frequency, location, and purpose of current Internet/e-mail use. The survey also contained questions addressing use of the Internet to access health-related information and specifically the use of the MHV Web site. Veterans were also queried as to the type of equipment (e.g., computer, smartphone) used to access the Internet and perceived barriers (e.g., computer literacy, lack of finances, privacy concerns) to Internet use. A separate set of questions addressed interest in engaging in CPT for various problems (“Would you be interested in computer programs to help you with any of the following?” followed by a list of eight problems that could potentially be addressed by available CPTs).
Analysis
Responses were tabulated and analyzed by frequency and measures of central tendency. Differences in aggregate responses between veterans who expressed interest in using computerized therapy and those who did not were compared and evaluated using chi-squared and t tests. Responses to seven questions on information technology use from substance use clinic patients were compared with those of the NSV sample and tested using chi-squared and t tests.
Results
Table 1 shows that a majority of veterans in the clinical sample were male, were white, had a high school education, and had a mean age of 52 years (standard deviation=10.9 years). Compared with the NSV sample, the clinical sample was on average 9 years younger (t 8,643=6.8, p<0.001) and included a 19% lower proportion of individuals with a college or advanced degree [χ2(4)=40.0, p<0.001], as well as a 26% higher proportion of African Americans [χ2(1)=96.5, p<0.001], a lower proportion of whites, and similar proportions of Hispanics and those of another race or ethnicity. In the clinical sample, individuals reporting only an alcohol or drug use disorder were equal in number (n=40, 27%), whereas approximately one-third reported both disorders. Two-thirds reported a comorbid psychiatric disorder.

When presented with a list of potential problems to be addressed by CPT, 124 respondents (82%) selected at least one problem for which they expressed interest in CPT treatment, whereas 91 (60%) selected more than one (Table 2). Respondents most frequently expressed interest in computerized therapy for drug or alcohol use (n=70, 47%), followed closely by therapies for sleep problems/insomnia, depression, and general problem solving, all selected by between 42% and 45% of veterans surveyed. Among those selecting multiple therapies, the most common additional therapy selected was for depression.
Interest in Computerized Therapy in a Sample of Veterans in Outpatient Treatment for Substance Use Disorders (n=151)
Over half of the clinic sample described using the Internet and/or e-mail at least occasionally (n=98 [65%] and n=97 [64%], respectively), proportions that were not statistically significantly different from responses to the same questions by the national sample of respondents to the NSV (Table 3). However, among Internet users in the clinical sample, only 76% (n=74) stated they used the Internet at least once a day or once a week, compared with 92% in the NSV sample [χ2(1)=34.0, p<0.001]. In addition, the location of Internet and e-mail use differed between the groups, with relatively less use at home and more use in other locations among the substance use clinic sample (Table 3). A relatively large number of clinic patients (n=40, 29%) indicated they had used the MHV Web site, a much larger proportion than those reporting MHV use in the NSV sample (3.2%) [χ2(1)=260.6, p<0.001], which included a large portion of veterans not using VHA services. Regarding the respondent's willingness to use the Internet for specific purposes, the proportion of clinic patients selecting “very willing” or “somewhat willing” was greatest for “obtaining information about VHA benefits” and “applying for VHA benefits” (n=98 [74%] and n=95 [71%], respectively). Regarding owning equipment with which to access the Internet/e-mail, only 70 clinic veterans (46%) indicated that they owned a computer or smartphone. When the sample was queried about health communication over the Internet or e-mail, the most commonly reported activity was “communicating with friends or family about health or healthcare.” When asked about barriers to Internet use, the most common barrier selected by the clinic sample was “don't know how to use a computer and/or type” (n=32, 21%), followed by “financial barriers” (n=24, 16%).

When clinic respondents who expressed interest in CPT were compared with those who did not, statistically significant differences emerged for some demographic and diagnostic variables but not for any of the variables addressing technology use, Internet use, or perceived barriers to use. The group interested in CPT were on average 5 years older (t 150=2.1, p=0.042), more likely to be African American [χ2(1)=8.8, p=0.032], and more likely to report a diagnosis of drug use disorder or more than one substance use or psychiatric disorder [χ2(1)=4.2, p=0.041 and χ2(1)=6.6, p=0.011, respectively]. When factors associated with of interest in the four most commonly selected CPT targets (substance use, depression, insomnia, and problem solving) were examined separately, statistically significant differences primarily reflected corresponding diagnostic considerations and not measures of computer/Internet use.
Discussion
In this survey of veterans with substance use disorders using VHA outpatient treatment services, there was frequently expressed interest in CPTs, as demonstrated by the fact that 82% of the sample indicated they were interested in at least one psychotherapy for a specific psychiatric and/or functional problem, most commonly substance use, depression, general problem solving, or insomnia, whereas 60% selected more than one. It is surprising that not one of the 23 measures describing current technology, Internet, or e-mail use or measures of barriers to information technology use was significantly associated with interest in participating in CPT. These findings support the potential for implementing CPTs as a treatment option among VHA patients in substance use treatment.
Few prior studies have directly evaluated interest in computerized therapies, and none specifically among individuals in substance use treatment. Such interest is likely a key factor in engagement and an eventual determinant of successful implementation of CPTs. 27 For comparison, a recent survey of older veterans revealed that over half expressed interest in using the Internet to track goals as well as manage anxiety and depression symptoms. 25 Similar surveys among individuals complaining of anxiety in the United Kingdom found similar results: 90% reported interest in computerized anxiety treatment in one study, and in another, one-half of individuals over the age of 65 years with depression and/or anxiety disorders indicated interest in CPT. 28,29 In addition, the latter studies also support the current finding that individuals interested in CPT were on average 5 years older than those who were not interested in CPT. Prior studies have also shown that disadvantaged populations for which there may be barriers to HIT use are just as willing to participate in computerized therapies as those who have more access. 30,31 These findings have also been bolstered by other studies suggesting that CPTs in general are as acceptable as face-to-face therapy and that the implementation of such therapies in clinical settings can be effective. 32,33
The second main finding in this study is that measures of current technology use and perceived barriers to HIT use were not associated with interest in CPT among veterans in substance use treatment. This finding encourages making CPTs available to clinic populations with substance use, as systematic barriers such as current use of and access to HIT do not appear to diminish interest, which is likely a key factor in the successful implementation of such programs. In addition, interest in CPT was significantly higher among individuals with a dual diagnosis, both an alcohol or drug use disorder, as well as older individuals and African Americans, all groups that many have thought would experience barriers that would discourage interest in using HIT. 3 These findings suggest that interest in this form of service delivery is not limited by complex mental health problems.
Few other studies have queried individuals directly about perceived barriers to the use of computerized interventions or HIT. This study found that not knowing how to use a computer or to type was the most commonly selected barrier to technology use, similar to a study of individuals with serious mental illness where expense, lack of computer skills, difficulty with typing, and difficulty with reading all emerged as relevant barriers. 3 Similarly, a Web-based survey of student perceptions of barriers to online learning revealed that lack of technical skills was a commonly selected barrier. 34 However, this finding still encourages the implementation of CPT in this group as selection of this barrier was not associated with reduced interest in participating in CPT, and it may be mitigated with proper support and training. Healthcare organizations such as VHA may be able to provide training programs that can fill gaps in technical training for people with little HIT experience.
However, trends in HIT use for the general population have been documented that may represent barriers to the widespread implementation of CPT. Technology ownership, access to an Internet connection, and Internet use are commonly but not consistently found to be lower in older age groups, minorities, and residents of rural locations, as well as those with lower levels of education, limited literacy, and low socioeconomic status. 15,16,18,23,35 –37 For individuals with mental illness, evidence of such barriers are mixed, with evidence of significant barriers found in some studies, 3 whereas others have found that individuals with chronic disease, mental health problems, and other stigmatizing conditions are actually more likely than others to use the Internet for health information. 9,38,39
For VHA service users, sociodemographic correlates of general and health-related Internet use are similar to those found in the general population. The NSV found that over 65% of veterans using VHA services also used the Internet, a proportion similar to that found among veterans who did not use VHA services and the nonveteran population, a finding replicated in this survey of veterans in VHA substance use treatment. 22,24 When use of the VHA's e-health portal, through which veterans can access their health record, manage prescriptions, and contact providers, was evaluated, 20% of NSV veterans in VHA care reported using the site, 24 a proportion that did not differ from the sample of veterans with substance use and mental health disorders examined in this study. These results indicate that similar systematic barriers to technology use likely exist for the general population, those with mental health and substance use disorders, and veterans. Although these barriers may affect eventual participation in CPT, they do not appear to affect interest in CPT among VHA service users.
Several limitations of this study deserve comment. As this is the only such survey of which the authors are aware and it occurred in a relatively small convenience sample at a single site, the generalizability of the results is unknown. In addition, the question that addressed the principal variable of interest was “Would you be interested in computer programs to help you with the following problems?” Respondents were left to define for themselves the meaning of “interested” and “computer programs.” However, we feel that this question, the associated list of specific functional and psychiatric problems, and the description of computer-based programs we provided supplied respondents with clear direction in this context. Although five of the most important potential barriers to information technology use were queried in this survey, this list may not have contained all potential personal and institutional barriers. Furthermore, interest in CPT may be related to prior of use of and provider attitudes toward such programs, and future surveys should include questions regarding these issues. In addition, future research that goes beyond self-reported interest and investigates the association between interest and uptake and engagement in such therapies are needed. Moreover, we were unable to identify individuals who completed the NSV and were also in treatment for substance use disorders for a more direct comparison. However, the proportion of current information technology users in this survey was not dissimilar from that of the 2010 NSV sample, although the treatment sample consisted of younger individuals, a higher proportion of African Americans, and those with less education.
CPTs are fast growing and wide-ranging and offer opportunities, in concert with face-to-face therapies, for lowering the cost of disease management among individuals with substance use disorders who use health service within and beyond VHA. Data on the efficacy of such programs are also promising. 7 However, CPTs have yet to be systematically implemented in VHA and similar safety-net healthcare systems, especially among those with substance use disorders. This survey of veterans in treatment for substance use disorders found that 82% of individuals expressed interest in CPT for a specific psychiatric and/or functional problem, and the findings support making CPTs available as a potentially feasible option for enhancing the care of veterans and others with substance use disorders.
