How can technology enhance cognitive behavioral therapy: the case of pediatric obsessive compulsive disorder
BMC Psychiatry volume 17, Article number: 226 (2017)
Many children with mental health disorders do not receive adequate treatment due to the uneven dissemination of resources, and other barriers to treatment. In the case of pediatric obsessive compulsive disorder treatment progress is also hindered by partial or non-response to treatment in addition to poor compliance. This debate paper focuses on new technologies as a potential vehicle to address the challenges faced by traditional treatment, with special reference to cognitive behavioral therapy for pediatric obsessive compulsive disorder. We discuss the achievements and challenges that previous studies have faced, debate ways to overcome them, and we offer specific suggestions for further research in the area.
Mental health disorders are highly prevalent, already among children and adolescents.Footnote 1 Up to one third of children suffer from a mental health disorder at some point during their lifetime [1, 2]. These disorders are associated with reduced quality of life, and with educational and work problems, and they involve high societal and personal costs . Despite the increase in evidence-based treatments, only 10–30% of children with mental health disorders seeking help receive adequate treatment [4,5,6]. This can be largely attributed to several barriers that limit the availability, accessibility, and acceptability of evidence-based treatments, such as a shortage of qualified therapists, and an insufficient dissemination of evidence-based care [7, 8]. Barriers to care may be further increased by logistic and financial obstacles, job- or school-related restrictions, and shame and stigma [8, 9].
Pediatric obsessive compulsive disorder (OCD) is a relatively common [4, 10,11,12], severe, and debilitating condition, characterized by obsessions and compulsions, and associated with high rates of comorbidity . If untreated, OCD symptoms often persist into adulthood , and lead to substantial impairments in family, academic and social functioning, and to a reduced quality of life [15,16,17]. Cognitive behavioral therapy (CBT) is the first-line treatment for pediatric OCD , and its effectiveness has been extensively demonstrated [19,20,21]. However, treatment for OCD is hampered by several problems [9, 22].
First of all, average improvement rates are limited and there are large individual differences in treatment effect [23, 24]. For partial and non-responders to CBT a combination of CBT and selective serotonin reuptake inhibitors (SSRIs) is recommended . However, some recent studies cast doubt on the additional value of medication. Although the POTS trial showed that, on average, combined treatment (CBT plus SSRI) was superior to CBT monotherapy for children with OCD, this effect could be attributed to the results of only one site. No superior effect of the combined treatment over CBT monotherapy was found for the other main site . Subsequently, Storch et al. compared the effectiveness of CBT plus pill placebo with CBT plus an SSRI, in which CBT was delivered by experienced therapists. In this study, no evidence was found for a superior effect of the combined treatment over CBT monotherapy . In line with these findings, Skarphedinsson et al. found that continuing CBT monotherapy was just as effective as adding an SSRI to continued CBT for initial non-responders to CBT monotherapy . Furthermore, the use of medication entails several disadvantages, such as possible adverse effects, a heightened chance of relapse by discontinuation, and unknown effects in the long term [25, 28]. As a result, many parents have reservations about the safety and long-term benefit of medication use . Taken together, this highlights the need for alternative options to the addition of medication to improve treatment for pediactric OCD.
Second, there are organizational and practical barriers to treatment for OCD. Although CBT is the treatment of choice, the availability of this treatment is limited, particularly in remote areas [4, 29]. There is a shortage of experienced therapists [29,30,31], and there are often long waiting lists for treatment . Furthermore, studies in adult OCD patients revealed that CBT was often poorly implemented [9, 33]. A substantial proportion of participants reported having received pharmacological treatments, or various psychotherapeutic treatments other than CBT, such as ‘talk-therapy’, supportive therapy, psychodynamic therapy and EMDR [9, 33]. If the use of CBT was reported this treatment often did not meet criteria for state-of-the-art CBT . In the case of pediatric OCD, the picture seems no better. Even in relatively prosperous countries like the United Kingdom and Norway, a lack of the availability of adequate treatment has been reported [4, 29]. An epidemiological study in the United Kingdom showed that only 12% of children with OCD identified in the survey had contacted child specialist services . In addition, a nationwide survey among clinicians in Norway revealed that only 62% of the respondents applied CBT for pediatric OCD, with CBT being mainly cognitive oriented and E/RP often missing. Furthermore, most clinicians were inexperienced in treating OCD, and expressed a need for training opportunities .
Further hampering insufficient dissemination of adequate treatment, distances from qualified therapists may limit the accessibility of CBT [9, 34]. In addition, practical problems with scheduling, treatment associated costs, and disorder-specific symptoms that restrict mobility, can further limit accessibility to treatment [9, 31, 35].
Shame and stigma, patients’ beliefs about treatment, such as reluctance to engage in exposure exercises, and low confidence because of prior treatment failures, are other factors that restrain patients from seeking treatment [9, 30, 35, 36]. Consequently, too few patients get adequate help despite the strong evidence in favor of an effective treatment [4, 29].
Technology empowered CBT
Modern technologies provide an opportunity to overcome at least some of these challenges. In this paper we use the term technology empowered CBT (tCBT) to refer to CBT based interventions integrating technology varying from basic online bibliotherapy to online self-help therapy, therapist-supported computerized CBT, smartphone applications (apps), traditional CBT delivered via telephone or videoconferencing, and combinations of these forms.
Recently, several initiatives have been taken to develop tCBT programs for OCD, and preliminary evidence shows that overall these programs yield positive effects [31, 37, 38]. Results from a meta-analysis of randomized controlled trials of tCBT programs for mainly adult OCD patients showed large effect sizes, and a stable effect over at least one month post-treatment. tCBT was found to be superior to control conditions (waitlist and relaxation), without a significant difference in efficacy between tCBT and traditional therapist-delivered CBT . tCBT programs however vary significantly in format, duration, intensity, length, and effect size, and evidence for their effectiveness is limited by the small number of trials, small sample sizes, and an emphasis on the adult population. This stresses the need for further research, especially in children.
The encouraging, albeit preliminary, results for tCBT programs for OCD, and the challenges faced by current treatment, pose several questions: how can new technologies help to make treatment more accessible, more user-friendly, and more cost-effective?; can tCBT be a vehicle for a more intensive and focused application of CBT principles?; how can we take advantage of the attractiveness of mobile technologies to children and offer an attractive treatment form and space positively affecting treatment motivation, adherence, and effect? The main aim of this paper is to discuss if and how technology can enhance CBT for pediatric OCD, guided by previous relevant studies and making suggestions for future interventions.
How can technology be used to improve the current situation of CBT for OCD?
In this section, we will discuss how tCBT can address several challenges currently faced by CBT, i.e., limited efficacy, insufficient availability and accessibility to adequate treatment, logistic barriers to treatment, and stigma.
tCBT can be delivered in a variety of formats, serving different goals. There are stand-alone programs, without any therapist contact, that can serve as the first step in a stepped care approach for patients with mild complaints, or provide an acceptable treatment option for patients who are reluctant to engage in face-to-face treatment [39, 40]. These programs may make treatment more cost-effective, improve the availability and accessibility of CBT, and meet issues of shame, stigma and convenience.
Other tCBT programs use technologies as the main intervention form supplemented with support of a therapist [37, 38]. Comparable to stand-alone programs, these programs offer the opportunity to improve the availability, accessibility, and cost-effectiveness of CBT, while offering more convenience for patients, as treatment can be (mainly) completed at home and therapist resources are used sparingly.
Technologies can also be used as an augmentation strategy to traditional CBT. In these formats CBT is delivered by a therapist, and supported or enriched by the use of technologies [32, 41]. This could address issues of accessibility and effectiveness of CBT by increasing treatment adherence and motivation.
Finally, technologies can serve as a medium to deliver therapist-administered CBT to patients at a distance, using tele- or videoconferencing [38, 42]. These formats improve the accessibility of treatment for patients who would otherwise not have access to treatment due to various geographical or transportation factors.
Concerns about tCBT
Despite the advantages that tCBT programs may entail, the development of these programs has raised concerns. A few studies have reported on clinicians’, children’s, and parents’ attitudes towards tCBT [43,44,45,46]. The most frequently reported concerns by clinicians were about drop-out rates, the suitability of tCBT for severe complaints, the therapeutic alliance, the availability of professional support, and standardized programs that are not tailored to individual needs [43, 45]. In a survey among a small sample of children and parents using child and adolescent mental health services, children reported both an interest in, and a reluctance for computerized therapy . Almost half of the children preferred to talk with a therapist rather than using a self-help computer program which was preferred by 9% of the sample. Concerns of parents included the lack of face-to-face contact with a therapist, safety issues related to internet usage, the negative effects of computer games (such as the addiction to games and social isolation), and children getting access to poor quality or harmful information when using the internet. Benefits of computerized (self-help) treatments identified by parents were related to reducing shame and stigma, opportunities for independent help seeking, access to good quality information, attractiveness of and familiarity with computer usage, and opportunities for peer support . In general, clinicians’, children’s, and parents’ attitudes were generally positive and encouraging for the use of tCBT [43,44,45]. In line with this, an online survey among 129 adults with OCD showed that overall tCBT was rated as an acceptable potential form of treatment. A minority of the respondents feared potential disadvantages, including preference for face-to-face therapist contact, concerns that one’s problems would be too severe for tCBT, and concerns about the lack of non-verbal communication . For the interpretation of the above results it is important to note that the majority of respondents in these studies had little knowledge about and no experience with tCBT [44, 45], which implies that reports mainly express expectations and are not based on experiences with tCBT. In addition, the studies reported on attitudes toward tCBT interventions in general, and did not distinguish between different formats. Nevertheless, clinicians’ as well as patients’ attitudes and believes about tCBT may affect the implementation of tCBT programs, and deserve attention.
Another type of concern is that the effectiveness of tCBT programs is not yet well established. Earlier studies provided that all of the earlier discussed tCBT formats can be effective in decreasing OCD symptoms, and that the overall effectiveness of tCBT might be comparable to therapist-administered CBT for OCD [31, 37, 38]. However, the reported effect sizes of tCBT programs for OCD are mainly based on adult samples, have varied substantially [31, 37], and results from a meta-analysis showed a non-significant trend suggesting that on average therapist-administered CBT was slightly more effective than tCBT .
Unfortunately, so far the literature does not provide specific information about which formats might be more effective than others. Nevertheless, findings from recent systematic reviews [31, 38], and published reports on tCBT for pediatric OCD, may provide clues to improve tCBT programs for OCD and to address the challenges of current treatment, taking concerns into account. A computerized search of Pubmed and PsycInfo databases, and a manual search within the reference lists of relevant papers identified nine studies reporting on tCBT interventions for pediatric OCD (see Table 1 for an overview of these studies). Most of these studies were recently published and therefore not included in the available meta-analysis and reviews. Below we discuss suggestions for future tCBT programs based on present findings, starting with a look at the recent systematic reviews on tCBT for mainly adult OCD, followed by studies on pediatric OCD.
What can we learn from recent systematic reviews?
First, more effective treatment programs are characterized by a better implementation of the exposure element of CBT [31, 38]. Although (almost) all programs include exposure, the degree and way in which exposure is incorporated varied, ranging from vicarious exposure on the screen to active exposure in real-life situations, and from following a self-help program to therapist-guided exposure using a web-camera . Results from a study of Greist et al. showed that the number of completed real-life exposure exercises correlated positively with OCD symptom reduction . These findings suggest that an intensive and focused application of exposure may be a core element of effective tCBT programs.
Second, incorporating therapist contact may lead to better treatment effects [31, 38]. In a study of Kenwright et al. evaluating computer-aided self-help for OCD, scheduled therapist contact contributed to reduced drop-out rates and to enhanced compliance compared with therapist contact on demand only .
A point of concern is the high drop-out rate in some studies, specifically for stand-alone programs [31, 38]. Possible explanations are the lack of therapist contact , and the inflexibility of fully-automated programs. Therapists can support and motivate patients leading to more engagement and treatment adherence, and can assist in solving upcoming problems, while stand-alone programs do not have the possibility to flexibly respond to personal situations, characteristics of patients, and unexpected problems [31, 38]. These results point to the additional value of therapist contact, and also to treatment programs that can, at least to some degree, address unique needs of individual patients.
What can we learn from studies in tCBT for pediatric OCD?
As shown in Table 1, a variety of tCBT programs for pediatric OCD have been developed. Although preliminary, the present studies provide encouraging results in improving the availability and accessibility of tCBT and reducing treatment related costs and burden by offering programs that can be completed (partly) at home. Furthermore, to address the issue of limited availability of CBT in remote areas, programs have been developed based on teleconferencing and videoconferencing instead of in-office meetings with a therapist.
In line with the findings above, two case examples in the study of Whiteside et al. point to the importance of therapist support to help families to maintain focus on treatment, and to be able to provide assistance by exposure exercises when needed. Another suggestion following from this study, is that tools offering space for personalized items may be preferred over pre-made items, as pre-made items may not always fit .
The study of Whiteside et al. provides preliminary evidence that technologies can augment therapist-delivered CBT. In a case example of a boy with severe OCD who lived too far away to frequently visit a therapist, an app was successfully used to facilitate exposure exercises at home between face-to-face treatment sessions, allowing for fewer frequent visits to the therapist. The app also generated data about the conductance of exposure exercises at home. These data provide therapists with information that can be used to solve possible problems in an early stage, and can be used by researchers to increase knowledge about effective ingredients of treatment . In addition, findings show that technology can be used to extend exposure from the therapist’s office to the patient’s daily life where the symptoms naturally occur [34, 49].
A study of Farrell et al. suggests that technology based interventions can fulfill a role in the maintenance and continuation of treatment effects after therapist-delivered CBT .
Some points of concern regarding technology-based approaches are also reported. Storch et al. pointed out that although overall experiences with their web-camera based approach were positive, therapists reported some difficulty establishing a therapeutic relationship, particularly with more oppositional children . Challenges in handling disruptive behavior during web-camera sessions were also reported by Comer et al. In addition, therapists experienced more difficulties with reading body language during web-camera sessions compared to face-to-face sessions . On the other hand, there is some evidence for CBT via videoconferencing in adults with OCD suggesting that a therapeutic relationship can be successfully established [51, 52].
In conclusion, tCBT programs can address at least some treatment barriers for pediatric OCD, although it must be borne in mind that most findings are preliminary, and that more robust study designs and larger samples are needed to extend these findings. Future research will have to address several issues. First of all, more information is needed about which factors can make tCBT treatments more effective and which treatment forms are most effective and for whom. We have discussed the available studies in an attempt to find some clues to answer this question. Second, recently developed tCBT programs for pediatric OCD primarily aim to improve the availability, accessibility, and cost-effectiveness of treatment, and do not address the problem that CBT is not sufficiently effective for all patients. A reasonable next step would be to use technologies to develop an enhanced treatment for pediatric OCD, addressing the issues of partial- and non-response, noncompliance, and drop-out from traditional CBT, alongside improving access and availability and making treatment more cost-effective. To address the limitations of previous studies and the challenges of the current situation, we discuss below an enhanced CBT (eCBT) concept for pediatric OCD.
How can technology be used to enhance treatment for pediatric OCD?
To address the issues of limited effectiveness and treatment drop-out from (t)CBT, the eCBT program needs a focused and intensive application of exposure [31, 38, 47], and should be therapist-guided to help families setting up adequate exposure exercises, to enhance treatment compliance, to motivate patients to adhere to the exposure exercises, to solve possible problems, and to address individual needs of patients [31, 34, 38, 48]. Therefore, therapist-administered CBT could be augmented with an app which has a monitoring, scaffolding and motivating function to support the exposure exercises between treatment sessions and encourage treatment compliance [34, 41]. The app might prompt patients to engage in exposure exercises, to support recording of homework and assessments, to encourage positive behavior, and to personalize treatment by allowing for individualized content and settings. Data on these activities gathered by the app provides the therapist with actual information that can be used to solve problems directly, set up new exposure exercises, and optimize the therapeutic process. Signs of noncompliance can be monitored regularly and early steps can be taken immediately to address problems. The app might allow for contact with the therapist between treatment sessions in order to prevent unnecessary stagnation in progress.
Furthermore, a partly home-based approach that could be accomplished by delivering CBT with exposure as the core element, through videoconferencing based sessions at home combined with in-office face-to-face therapist contact, might overcome barriers to care, and may offer more convenience for the children and their families through reducing travelling time, costs, and stigma [36, 49, 50, 53, 54]. Videoconferencing sessions may further add to in-office CBT as delivering interventions in settings in which the problems occur may increase ecologically validity and encourage the generalization of principles from therapy-related to natural settings . It also addresses the concerns and preferences of children and parents by incorporating visual contact with the therapist [43, 46]. Finally, videoconferencing sessions offer the opportunity to easily intensify treatment, if required, by extra web-camera guided exposure exercises between sessions, which may further reduce non-response. To address concerns regarding therapeutic alliance, videoconferencing sessions can be combined with face-to-face sessions .
Modern technologies, such as apps, can also contribute to the attractiveness of treatment for children, which may further encourage treatment compliance and prevent treatment drop-out [31, 38, 55]. The use of technological applications fits easily into the lives of today’s children, and may offer a user-friendly tool [41, 44]. For example, video clips of children with OCD can be used for psychoeducation, which may reduce shame, and applications can incorporate interactive elements for administrating exposure exercises, tracking treatment progress, rewarding positive behavior, and building a relapse prevention plan which may have a motivational effect alongside personalizing treatment. An app can also be used for generating psychological data (for example in vivo assessments of mood and symptoms), as well as physiological data (for example by connecting the app to a wristband measuring physiological indicators for stress during exposure) in a user-friendly way, which can serve clinical as well as research purposes, both of which may contribute to the improvement of treatment [32, 41].
Finally, for a successful implementation of such a program, training for users can be offered as many therapists may not have experience with tCBT programs, and concerns of clinicians towards this form of treatment [43, 45], and how tCBT can address these concerns will have to be discussed with them. For example, when therapists are concerned about the suitability of tCBT for severe or difficult-to-treat symptoms, treatment can be intensified by extra videoconferencing sessions between the regular sessions to guide exposure sessions at home. Regarding concerns about drop-out rates, a motivating app supporting homework exercises for clients and providing feedback about treatment progress to therapists may improve treatment compliance and prevent pre-term treatment drop out.
In addition, where applicable, the concerns of children and parents related to tCBT will have to be addressed by the therapist before the start of treatment . Safety and privacy related to the usage of technological applications need to be ensured. Finally, acceptability and feasibility studies of tCBT treatments are needed to further improve tCBT treatment packages.
If such an enhanced CBT program has been proven to be effective in pediatric OCD, the model could be modified and applied to other mental health disorders, as many of the treatment barriers and limitations discussed in this paper are not restricted to OCD . An app which supports exercises at home and thereby encourages treatment compliance could also be used as an augmentation to CBT for other disorders, for example supporting exposure exercises for anxiety disorders, behavioral activation for depression, E/RP or habit reversal for tic disorders, and healthy eating patterns in eating disorders. In addition, videoconferencing sessions to guide exposure sessions at home could be incorporated into exposure based treatments for a variety of disorders. Overall, the use of modern technologies, such as apps, may be attractive for all young people and could therefore offer a useful medium for the delivery of CBT to a range of disorders [41, 55,56,57,58].
Technological innovations offer a unique opportunity to address limitations associated with traditional treatment such as access, suitability, expense, and stigma. Furthermore, the ever-increasing integration of sophisticated electronic media into young people’s lives seems to offer a good opportunity to use it also for therapeutic purposes. In the case of pediatric OCD, preliminary results for CBT programs integrating technology are encouraging, but several challenges need to be addressed by enhancing tCBT programs with the focus on non-response, non-compliance, and preterm treatment drop-outs. This may contribute to a more effective treatment for pediatric OCD, and could offer a framework for other disorders too.
