Usage and longitudinal effectiveness of a Web-based self-help cognitive behavioral therapy program for panic disorder

Therapist Behaviours in Internet-Delivered Cognitive Behaviour Therapy: Analyses of E-Mail Correspondence in the Treatment of Generalized Anxiety Disorder

Background: Internet-delivered cognitive behaviour therapy (iCBT) has been found to be an effective way to disseminate psychological treatment, and support given by a therapist seems to be important in order to achieve good outcomes. Little is known about what the therapists actually do when they provide support in iCBT and whether their behaviour influences treatment outcome. Aims: This study addressed the content of therapist e-mails in guided iCBT for generalized anxiety disorder. Method: We examined 490 e-mails from three therapists providing support to 44 patients who participated in a controlled trial on iCBT for generalized anxiety disorder. Results: Through content analysis of the written correspondence, eight distinguishable therapist behaviours were derived: deadline flexibility, task reinforcement, alliance bolstering, task prompting, psychoeducation, self-disclosure, self-efficacy shaping, and empathetic utterances. We found that task reinforcement, task prompting, self-efficacy shaping and empathetic utterances correlated with module completion. Deadline flexibility was negatively associated with outcome and task reinforcement positively correlated with changes on the Penn State Worry Questionnaire. Conclusions: Different types of therapist behaviours can be identified in iCBT, and though many of these behaviours are correlated to each other, different behaviours have an impact on change in symptoms and module completion.

Online CBT I: Bridging the Gap Between Eliza and Modern Online CBT Treatment Packages

Reviews have demonstrated large effect sizes when using computerised cognitive behaviour therapy (CBT) protocols for treating anxiety, depression and health related concerns. However, the amount of therapist contact per user seems to be the most significant prognostic indicator. Thus, in some ways current online interventions can be viewed primarily as an extension of one-on-one therapy. The present article provides guidelines for targeting this limitation of online psychological interventions. The goal is to mimic the therapeutic relationship using a computer, without having any therapist involved. Consequently, thousands of users would be able to receive treatment simultaneously, reaching a wider audience, which was the initial goal of the online model. The development of a treatment program using file audit data is suggested as an alternative to having an individual therapist for each user. This is done by allowing the ‘computer psychologist’ to tailor individualised treatments for each user based on their psychological profile. The user is provided with individualised corrective feedback based on a set of prewritten responses to common faulty thoughts. A new paradigm is proposed for online treatment delivery.

Build it, and will they come? Unexpected findings from a study on a Web-based intervention to improve colorectal cancer screening

Given the extensive use of the Internet for health information, Web-based health promotion interventions are widely perceived as an effective communication channel. The authors conducted this study to determine use of a Web-based intervention intended to improve colorectal cancer screening in a population of women who are at average risk and noncompliant to current screening recommendations. The study was a randomized controlled trial designed to compare the effectiveness of colorectal cancer screening educational materials delivered using the Internet versus a printed format. In 3 years, 391 women seen for routine obstetrics/gynecology follow-up at 2 academic centers provided relevant survey information. Of these, 130 were randomized to the Web intervention. Participants received voluntary access to a password-protected, study-specific Web site that provided information about colorectal cancer and colorectal cancer screening options. The main outcome measures were self-reported and actual Web site use. Only 24.6% of women logged onto the Web site. Age was the only variable that differentiated users from nonusers (p = .03). In contrast, 16% of participants self-reported Web use. There was significant discordance between the veracity of actual and self-reported use (p = .004). Among true users, most (81%) logged on once only. These findings raise questions about how to increase use of important health communication interventions.

Nonuse and dropout attrition for a web-based mental health intervention delivered in a post-disaster context

Web-based mental health interventions are an excellent means to provide low cost, easily accessible care to disaster-affected populations shortly after exposure to an event. However, the extent that individuals will access and use such interventions is largely unknown. We examined predictors of nonuse and dropout attrition for a web-based mental health intervention in 1,249 randomly selected adults in two Texas counties--Galveston and Chambers--that were hardest hit by Hurricane Ike in 2008. Participants completed a structured telephone interview to assess demographics, impact of disaster exposure, history of traumatic events, mental health symptoms, and service utilization. Following the interview, participants were oriented and invited to access a web-based intervention and then contacted four months later to evaluate their use of the website and mental health functioning. Separate logistic and Poisson regressions were used to determine baseline predictors of nonuse attrition, predictors of dropout attrition, and predictors of completing intervention modules. Results suggested that the strongest buffer against nonuse attrition and dropout attrition was having considered seeking formal mental health treatment. Results of this study inform the development and dissemination of web-based interventions in future disaster affected areas.

Mini-KiSS Online: an Internet-based intervention program for parents of young children with sleep problems - influence on parental behavior and children's sleep

PURPOSE

Behavioral sleep problems are highly common in early childhood. These sleep problems have a high tendency to persist, and they may have deleterious effects on early brain development, attention, and mood regulation. Furthermore, secondary effects on parents and their relationship are documented. Negative parental cognition and behavior have been found to be important influencing factors of a child's behavioral sleep problems. Therefore, in the current study we examined the acceptance and efficacy of a newly developed Internet-based intervention program called Mini-KiSS Online for sleep disturbances for children aged 6 months to 4 years and their parents.

PATIENTS AND METHODS

Fifty-five children (54.54% female; aged 8-57 months) suffering from psychophysiological insomnia or behavioral insomnia participated in the 6-week online treatment. Sleep problems and treatment acceptance were examined with a sleep diary, anamnestic questionnaires, a child behavior checklist (the Child Behavior Checklist 1.5-5), and treatment evaluation questionnaires.

RESULTS

The evaluation questionnaires showed a high acceptance of Mini-KiSS Online. Parents would recommend the treatment to other families, were glad to participate, and reported that they were able to deal with sleep-related problems of their child after Mini-KiSS Online. Parental behavior strategies changed with a reduction of dysfunctional strategies, such as staying or soothing the child until they fell asleep, allowing the child to get up again and play or watch TV, or reading them another bedtime story. Frequency and duration of night waking decreased as well as the need for external help to start or maintain sleep. All parameters changed significantly, not only in the questionnaires but also in the sleep diary.

CONCLUSION

Mini-KiSS Online is shown to be a highly accepted and effective treatment to change parental behavior and reduce behavioral sleep problems in early childhood.

Outcome predictors in guided and unguided self-help for social anxiety disorder

Internet-based self-help with therapist guidance has shown promise as an effective treatment and may increase access to evidence-based psychological treatment for social anxiety disorder (SAD). Although unguided self-help has been suggested primarily as a population-based preventive intervention, some studies indicate that patients with SAD may profit from unguided self-help. Gaining knowledge about predictors of outcome in guided and unguided self-help for SAD is important to ensure that these interventions can be offered to those who are most likely to respond. Utilizing a sample of 245 patients who received either guided or unguided self-help for SAD, the present study examined pre-treatment symptoms and program factors as predictors of treatment adherence and outcome. The results were in line with previous findings from the face-to-face treatment literature: namely, the intensity of baseline SAD symptoms, but not depressive symptoms, predicted treatment outcomes in both unguided and guided self-help groups. Outcomes were unrelated to whether a participant has generalized versus specific SAD. Furthermore, for the unguided self-help group, higher credibility ratings of the treatment program were associated with increased treatment adherence. The findings suggest that guided and unguided self-help may increase access to SAD treatment in a population that is more heterogeneous than previously assumed.

Mobile mental health: review of the emerging field and proof of concept study

BACKGROUND

The ubiquitous nature of mobile phones and their increasing functionality make them an ideal medium for the delivery of large-scale public health information and interventions. While mobile phones have been used to this end in behavioural and physical health settings, their role in monitoring and managing mental health is in its infancy.

AIMS

The purpose of this paper is (1) to provide an overview of the field of mobile mental health and (2) by way of illustration, describe an initial proof of concept study carried out to assess the potential utility and effectiveness of a newly developed mobile phone and web-based program in the management of mild-to-moderate stress, anxiety and depression.

METHODS

Over 6 weeks, participants were given access to "myCompass": an interactive self-help program, which includes real-time self-monitoring with short message service prompts and brief online modules grounded in cognitive behavioural therapy.

RESULTS

Preliminary analyses found that participants' symptoms of stress, anxiety, depression and overall psychological distress were significantly reduced after using myCompass. Improvements were also found in functional impairment and self-efficacy.

CONCLUSIONS

These preliminary results support the feasibility of implementing mobile phone-based interventions with the potential of improving psychological wellbeing.

Computerized continuing care support for alcohol and drug dependence: a preliminary analysis of usage and outcomes

The central aim of this administrative data analysis was to examine usage of a Web-based disease management program designed to provide continuing recovery support to patients discharged from residential drug and alcohol treatment. Tailored clinical content was delivered in a multimedia format over the course of 18 months posttreatment. The program also included access to a recovery coach across the 18 months. Consistent with other disease management programs, program usage decreased over time. A small subsample of patients accessed a large number of program modules in the year following treatment; these patients had significantly higher abstinence rates and consumed less alcohol than patients accessing few or no modules. Regression analyses revealed a significant relationship between the number of modules accessed and substance use outcomes in the year following treatment when controlling for motivation, self-efficacy, and pretreatment substance use. Limiting the analyses to only the more compliant patients did not reduce the magnitude of these effects. These preliminary results suggest that computerized support programs may be beneficial to patients recently treated for drug and alcohol issues. Methods to increase program engagement need additional study.

The use of e-health applications for anxiety and depression in young people: challenges and solutions

AIM

E-health applications are effective. However, challenges to their uptake amongst youth need to be investigated. This paper aims to explore the barriers to the use of these programs by young people and the methods by which these barriers might be overcome.

METHODS

Qualitative review of research literature.

RESULTS

Barriers to the use of these programs included the difficulty in engaging young people in their use, perceptions that the programs have low adherence, and clinician concerns about their value, effectiveness and safety. Evidence to date suggests that more research is needed to understand the reasons more young people do not engage with them. However, adherence rates are reasonable when properly benchmarked and the applications can be appropriately implemented in clinical and educational settings.

CONCLUSIONS

Optimal methods for implementing these applications will require further targeted research.

Online counseling via e-mail for breast cancer patients on the German internet: preliminary results of a psychoeducational intervention

OBJECTIVES

The internet offers new possibilities in psychosocial patient care. However, empirical data are lacking for oncological patients. A field-experimental study was conducted to obtain initial data to enable evaluation of the effectiveness of online counseling via e-mail for breast cancer patients. A secondary objective was to explore how patients reached by the service can be characterized on psychosocial status and illness.

METHODS

On a dedicated German-language website, 235 breast cancer patients registered for psychosocial counseling via e-mail. 133 registrants were randomly assigned to a treatment group to receive immediate counseling or to a waiting list control group. The two-month counseling session took the form of a psychoeducation, individually tailored to each patient. Psychosocial outcome measures including psychological distress (BSI) and quality of life (EORTC QLQ-C30) were assessed at registration and at a two-month follow-up. Descriptive data were recorded at registration. At the conclusion of the program, participants were asked to complete a patient satisfaction questionnaire (ZUF-8).

RESULTS

BSI responses showed that 85% of all patients were initially diagnosable with comorbid psychopathology. Despite high severity of distress and attendant large reductions in quality of life, 72% of all patients were not obtaining conventional assistance. Among counseling participants (n=31), no significant improvements in distress or quality of life were found in comparison to the control group (n=34), but patient satisfaction was nonetheless high.

CONCLUSION

The study demonstrates that online counseling via e-mail reaches patients with unmet therapeutic needs, but also indicated its limitations, suggesting that the online setting may be most useful for prompting and supporting a transition to conventional counseling services.

Expressive writing is a promising therapeutic modality for the management of IBS: a pilot study

OBJECTIVES

We sought to test the effectiveness of expressive writing about irritable bowel syndrome (IBS) on disease severity, IBS-related cognition (perceived control over the illness or adaptive cognition), and IBS-specific quality of life.

METHODS

This was an exploratory pilot study, during which subjects with IBS were asked to write at an online portal for 30 min on 4 consecutive days about their deepest thoughts, emotions, and beliefs regarding the disease and their perception of its effects (writing group). The IBS severity scale (IBSSS), functional bowel disease-related cognition (CG-FBD), catastrophizing/coping (CT3), and IBS-specific quality of life (IBS-QOL) were measured at baseline and at 1 and 3 months' follow-up. Subjects who did not start writing for 3 weeks were asked to complete questionnaires without writing (non-writers group). Within-group comparisons pre- and post-assessment were compared. In addition, the writing and non-writers groups were compared. Linear mixed-effects models were used to assess the outcome measures over time (1 and 3 months).

RESULTS

A total of 103 subjects were enrolled in the study (writing group, n=82; non-writers group, n=21). The mean age of all participants was 43 years (s.d. ±12), and the majority (91%) were female. The mean duration of IBS was 6.8 years (s.d. ±3.5); 102 subjects (99‰) had received physician-directed care for the disease. There were no significant differences between the writing and non-writers groups in baseline measurements. For the writing group at 1 and 3 months, the IBSSS improved significantly (+37.4 (±10.8), P=0.0012 and +53.8 (±13), P=0.0002, respectively) and this was not seen in the non-writers group. Similarly, the CG-FBD improved in the writing group by 0.58 (±0.2, P=0.006) at 3 months, although the changes in IBS-QOL did not reach clinical or statistical significance.

CONCLUSIONS

In this exploratory study, expressive writing improved IBS disease severity and cognition in subjects with longer-term duration of the disease. A large, controlled study is warranted to evaluate the therapeutic potential of this novel modality for adjunctive management of IBS in the outpatient setting.

Internet-versus group-administered cognitive behaviour therapy for panic disorder in a psychiatric setting: a randomised trial

BACKGROUND

Internet administered cognitive behaviour therapy (CBT) is a promising new way to deliver psychological treatment, but its effectiveness in regular care settings and in relation to more traditional CBT group treatment has not yet been determined. The primary aim of this study was to compare the effectiveness of Internet-and group administered CBT for panic disorder (with or without agoraphobia) in a randomised trial within a regular psychiatric care setting. The second aim of the study was to establish the cost-effectiveness of these interventions.

METHODS

Patients referred for treatment by their physician, or self-referred, were telephone-screened by a psychiatric nurse. Patients fulfilling screening criteria underwent an in-person structured clinical interview carried out by a psychiatrist. A total of 113 consecutive patients were then randomly assigned to 10 weeks of either guided Internet delivered CBT (n = 53) or group CBT (n = 60). After treatment, and at a 6-month follow-up, patients were again assessed by the psychiatrist, blind to treatment condition.

RESULTS

Immediately after randomization 9 patients dropped out, leaving 104 patients who started treatment. Patients in both treatment conditions showed significant improvement on the main outcome measure, the Panic Disorder Severity Scale (PDSS) after treatment. For the Internet treatment the within-group effect size (pre-post) on the PDSS was Cohen's d = 1.73, and for the group treatment it was d = 1.63. Between group effect sizes were low and treatment effects were maintained at 6-months follow-up. We found no statistically significant differences between the two treatment conditions using a mixed models approach to account for missing data. Group CBT utilised considerably more therapist time than did Internet CBT. Defining effect as proportion of PDSS responders, the cost-effectiveness analysis concerning therapist time showed that Internet treatment had superior cost-effectiveness ratios in relation to group treatment both at post-treatment and follow-up.

CONCLUSIONS

This study provides support for the effectiveness of Internet CBT in a psychiatric setting for patients with panic disorder, and suggests that it is equally effective as the more widely used group administered CBT in reducing panic-and agoraphobic symptoms, as well as being more cost effective with respect to therapist time.

Web-based therapist-assisted cognitive behavioral treatment of panic symptoms: a randomized controlled trial with a three-year follow-up

BACKGROUND

Internet-delivered treatment may reduce barriers to care in those unwilling or unable to access traditional forms of treatment.

OBJECTIVE

To assesses the efficacy of web-based therapist-assisted cognitive behavioral treatment (web-CBT) of panic symptoms.

DESIGN

A randomized waiting-list controlled trial with an uncontrolled three-year follow-up.

PARTICIPANTS

A community sample of 58 participants with chronic panic symptoms of varying severity (immediate treatment: n=27, waiting-list control: n=31).

OUTCOME MEASURES

The primary outcome measures were a one-week Panic Diary and the Panic Disorder Severity Scale - Self-Report (PDSS-SR); secondary measures were the Agoraphobic Cognitions Questionnaire (ACQ), the Body Sensations Questionnaire (BSQ), the Mobility Inventory - Alone subscale (MI-AAL), and the Depression Anxiety Stress Scales (DASS-42).

RESULTS

In the RCT, 54 participants (93%) completed posttest measurements. With regard to the primary outcome measures, intention-to-treat ANCOVAs revealed that participants in the treatment condition improved more than the participants in the waiting-list control condition (p<.03), with a pooled between-group effect size of d=.7. After three years (n=47; 81% study compliance), effects were more pronounced.

CONCLUSION

The results demonstrate the efficacy of therapist-assisted web-CBT in the treatment of panic symptoms.

Methodological issues in research on web-based behavioral interventions

BACKGROUND

Web-based behavioral intervention research is rapidly growing.

PURPOSE

We review methodological issues shared across Web-based intervention research to help inform future research in this area.

METHODS

We examine measures and their interpretation using exemplar studies and our research.

RESULTS

We report on research designs used to evaluate Web-based interventions and recommend newer, blended designs. We review and critique methodological issues associated with recruitment, engagement, and social validity.

CONCLUSIONS

We suggest that there is value to viewing this burgeoning realm of research from the broader context of behavior change research. We conclude that many studies use blended research designs, that innovative mantling designs such as the Multiphase Optimization Strategy and Sequential Multiple Assignment Randomized Trial methods hold considerable promise and should be used more widely, and that Web-based controls should be used instead of usual care or no-treatment controls in public health research. We recommend topics for future research that address participant recruitment, engagement, and social validity.

Attrition from self-directed interventions: investigating the relationship between psychological predictors, intervention content and dropout from a body dissatisfaction intervention

The aims of this study were to (a) identify the predictors of attrition from a fully self-directed intervention, and (b) to test whether an intervention to increase gratitude is an effective way to reduce body dissatisfaction. Participants (N=479, from the United Kingdom) aged 18-76 years took part in a self-help study via the Internet and were randomized to receive one of two interventions, gratitude diaries (n=130), or thought monitoring and restructuring (n=118) or a waitlist control (n=231) for a two week body dissatisfaction intervention. The gratitude intervention (n=40) was as effective as monitoring and restructuring (n=22) in reducing body dissatisfaction, and both interventions were significantly more effective than the control condition (n=120). Participants in the gratitude group were more than twice as likely to complete the intervention compared to those in the monitoring and restructuring group. Intervention content, baseline expectancy and internal locus of control significantly predicted attrition. This study shows that a gratitude intervention can be as effective as a technique commonly used in cognitive therapy and is superior in retaining participants. Prediction of attrition is possible from both intervention content and psychological variables.

Comparison of trial participants and open access users of a web-based physical activity intervention regarding adherence, attrition, and repeated participation

BACKGROUND

Web-based interventions are popular for promoting healthy lifestyles such as physical activity. However, little is known about user characteristics, adherence, attrition, and predictors of repeated participation on open access physical activity websites.

OBJECTIVE

The focus of this study was Active-online, a Web-based individually tailored physical activity intervention. The aims were (1) to assess and compare user characteristics and adherence to the website (a) in the open access context over time from 2003 to 2009, and (b) between trial participants and open access users; and (2) to analyze attrition and predictors of repeated use among participants in a randomized controlled trial compared with registered open access users.

METHODS

Data routinely recorded in the Active-online user database were used. Adherence was defined as: the number of pages viewed, the proportion of visits during which a tailored module was begun, the proportion of visits during which tailored feedback was received, and the time spent in the tailored modules. Adherence was analyzed according to six one-year periods (2003-2009) and according to the context (trial or open access) based on first visits and longest visits. Attrition and predictors of repeated participation were compared between trial participants and open access users.

RESULTS

The number of recorded visits per year on Active-online decreased from 42,626 in 2003-2004 to 8343 in 2008-2009 (each of six one-year time periods ran from April 23 to April 22 of the following year). The mean age of users was between 38.4 and 43.1 years in all time periods and both contexts. The proportion of women increased from 49.5% in 2003-2004 to 61.3% in 2008-2009 (P< .001). There were differences but no consistent time trends in adherence to Active-online. The mean age of trial participants was 43.1 years, and 74.9% were women. Comparing contexts, adherence was highest for registered open access users. For open access users, adherence was similar during the first and the longest visits; for trial participants, adherence was lower during the first visits and higher during the longest visits. Of registered open access users and trial participants, 25.8% and 67.3% respectively visited Active-online repeatedly (P< .001). Predictors of repeated use were male sex (odds ratio [OR] = 1.2, 95% confidence interval [CI] = 1.04-1.38) and increasing age category in registered open access users, and age 46-60 versus < 30 years (OR = 3.04, 95% CI = 1.25-7.38) and Swiss nationality (OR(nonSwiss)= 0.64, 95% CI = 0.41-1.00) in trial participants. Despite reminder emails, attrition was much higher in registered open access users compared with trial participants, with a median lifetime website usage of 0 days in open access users and 290 days in trial participants.

CONCLUSIONS

Adherence, patterns of use, attrition, and repeated participation differed between trial participants and open access users. Reminder emails to encourage repeated participation were effective for trial participants but not for registered open access users. These issues are important when interpreting results of randomized controlled effectiveness trials.

Adherence in internet interventions for anxiety and depression

Background

Open access websites which deliver cognitive and behavioral interventions for anxiety and depression are characterised by poor adherence. We need to understand more about adherence in order to maximize the impact of Internet-based interventions on the disease burden associated with common mental disorders.

Objective

The aims of this paper are to review briefly the adherence literature with respect to Internet interventions and to investigate the rates of dropout and compliance in randomized controlled trials of anxiety and depression Web studies.

Methods

A systematic review of randomized controlled trials using Internet interventions for anxiety and depression was conducted, and data was collected on dropout and adherence, predictors of adherence, and reasons for dropout.

Results

Relative to reported rates of dropout from open access sites, the present study found that the rates of attrition in randomized controlled trials were lower, ranging from approximately 1 - 50%. Predictors of adherence included disease severity, treatment length, and chronicity. Very few studies formally examined reasons for dropout, and most studies failed to use appropriate statistical techniques to analyze missing data.

Conclusions

Dropout rates from randomized controlled trials of Web interventions are low relative to dropout from open access websites. The development of theoretical models of adherence is as important in the area of Internet intervention research as it is in the behavioral health literature. Disease-based factors in anxiety and depression need further investigation.

Using the Internet to provide cognitive behaviour therapy

A new treatment form has emerged that merges cognitive behaviour therapy with the Internet. By delivering treatment components, mainly in the form of texts presented via web pages, and provide ongoing support using e-mail promising outcomes can be achieved. The literature on this novel form of treatment has grown rapidly over recent years with several controlled trials in the field of anxiety disorders, mood disorders and behavioural medicine. For some of the conditions for which Internet-delivered CBT has been tested, independent replications have shown large effect sizes, for example in the treatment of social anxiety disorder. In some studies, Internet-delivered treatment can achieve similar outcomes as in face-to-face CBT, but the literature thus far is restricted mainly to efficacy trials. This article provides a brief summary of the evidence, comments on the role of the therapist and for which patient and therapist this is suitable. Areas of future research and exploration are identified.

Predictors of drop-out in an Internet study of men who have sex with men

Researchers have suggested the rising use of Internet to look for sexual partners is an important contributor to the resurgence in the incidence of sexually transmitted diseases (STDs) and HIV among men who have sex with men (MSM). Web-based samples of this population reflect good geographical diversity for research, but a high drop-out rate creates a significant potential for bias, misrepresentation of population, and misinterpretation of data. This study aims to describe the demographics of an Internet sample of MSM and the differences between the completers and drop-outs. We analyzed data obtained from a cross-sectional study using an online self-administered questionnaire for males, 18 years or older, who were current U.S. residents, and who had sex with men. Of 850 eligible participants, 404 (47.5%) were labeled as drop-outs. The completers and drop-outs differed significantly in age, education, country of birth, health insurance, time spent on Internet, location of computer access, types of sites visited, profile information, last homosexual experience, methods used to determine safety of partners, and type of sexual activities on real meets. Almost half of the participants dropped out before completion. Although the two groups did not differ in many of the items, high drop-out rates are a threat to the validity of such data. Drop-out constitutes a significant bias in Internet sexuality research and must be considered while interpreting the results of such studies.

Health coaching via an internet portal for primary care patients with chronic conditions: a randomized controlled trial

BACKGROUND

Efforts to enhance patient-physician communication may improve management of underdiagnosed chronic conditions. Patient internet portals offer an efficient venue for coaching patients to discuss chronic conditions with their primary care physicians (PCP).

OBJECTIVES

We sought to test the effectiveness of an internet portal-based coaching intervention to promote patient-PCP discussion about chronic conditions.

RESEARCH DESIGN

We conducted a randomized trial of a nurse coach intervention conducted entirely through a patient internet-portal.

SUBJECTS

Two hundred forty-one patients who were registered portal users with scheduled PCP appointments were screened through the portal for 3 target conditions, depression, chronic pain, mobility difficulty, and randomized to intervention and control groups.

MEASURES

One-week and 3-month patient surveys assessed visit experiences, target conditions, and quality of life; chart abstractions assessed diagnosis and management during PCP visit.

RESULTS

Similar high percentages of intervention (85%) and control (80%) participants reported discussing their screened condition during their PCP visit. More intervention than control patients reported their PCP gave them specific advice about their health (94% vs. 84%; P = 0.03) and referred them to a specialist (51% vs. 28%; P = 0.002). Intervention participants reported somewhat higher satisfaction than controls (P = 0.07). Results showed no differences in detection or management of screened conditions, symptom ratings, and quality of life between groups.

CONCLUSIONS

Internet portal-based coaching produced some possible benefits in care for chronic conditions but without significantly changing patient outcomes. Limited sample sizes may have contributed to insignificant findings. Further research should explore ways internet portals may improve patient outcomes in primary care. ClinicalTrials.gov registration NCT00130416.

Randomized Controlled Trial of Web-Based Treatment of Social Phobia Without Clinician Guidance

Objective: The aim of the present study was (Shyness 4) to determine which level of reminder best facilitated a clinician-free Internet treatment for social phobia.

Method: A pragmatic randomized controlled trial of an enhanced Internet treatment, with and without weekly telephone reminders, was done. Participants consisted of 163 volunteers with social phobia, who completed six lessons of computerized cognitive behaviour therapy for social phobia with complex automated reminders. Main outcome measures were the Social Interaction Anxiety Scale and Social Performance Scale.

Results: Social phobia improved in both groups. Adherence (68% vs 81%) and improvement in social phobia (effect size = 0.86 vs 1.15) was better in the group with the added telephone reminders.

Conclusions: Enhanced Internet-based cognitive behaviour therapy without clinician guidance is a strong treatment for social phobia. Telephone reminders further improve outcome. Because both interventions are effective, it is a pragmatic decision for a practice or a service as to whether the 33% increase in efficacy justifies 1 h of practice nurse or receptionist time.

Rates and determinants of uptake and use of an internet physical activity and weight management program in office and manufacturing work sites in England: cohort study

BACKGROUND

Internet-based physical activity (PA) and weight management programs have the potential to improve employees' health in large occupational health settings. To be successful, the program must engage a wide range of employees, especially those at risk of weight gain or ill health.

OBJECTIVE

The aim of the study was to assess the use and nonuse (user attrition) of a Web-based and monitoring device-based PA and weight management program in a range of employees and to determine if engagement with the program was related to the employees' baseline characteristics or measured outcomes.

METHODS

Longitudinal observational study of a cohort of employees having access to the MiLife Web-based automated behavior change system. Employees were recruited from manufacturing and office sites in the North West and the South of England. Baseline health data were collected, and participants were given devices to monitor their weight and PA via data upload to the website. Website use, PA, and weight data were collected throughout the 12-week program.

RESULTS

Overall, 12% of employees at the four sites (265/2302) agreed to participate in the program, with 130 men (49%) and 135 women (51%), and of these, 233 went on to start the program. During the program, the dropout rate was 5% (11/233). Of the remaining 222 Web program users, 173 (78%) were using the program at the end of the 12 weeks, with 69% (153/222) continuing after this period. Engagement with the program varied by site but was not significantly different between the office and factory sites. During the first 2 weeks, participants used the website, on average, 6 times per week, suggesting an initial learning period after which the frequency of website log-in was typically 2 visits per week and 7 minutes per visit. Employees who uploaded weight data had a significant reduction in weight (-2.6 kg, SD 3.2, P< .001). The reduction in weight was largest for employees using the program's weight loss mode (-3.4 kg, SD 3.5). Mean PA level recorded throughout the program was 173 minutes (SE 12.8) of moderate/high intensity PA per week. Website interaction time was higher and attrition rates were lower (OR 1.38, P= .03) in those individuals with the greatest weight loss.

CONCLUSIONS

This Web-based PA and weight management program showed high levels of engagement across a wide range of employees, including overweight or obese workers, shift workers, and those who do not work with computers. Weight loss was observed at both office and manufacturing sites. The use of monitoring devices to capture and send data to the automated Web-based coaching program may have influenced the high levels of engagement observed in this study. When combined with objective monitoring devices for PA and weight, both use of the website and outcomes can be tracked, allowing the online coaching program to become more personalized to the individual.

Shyness 3: randomized controlled trial of guided versus unguided Internet-based CBT for social phobia

OBJECTIVE

In two previous randomized controlled trials Titov et al. demonstrated significant benefit from an Internet- and email-based treatment programme for social phobia. The present study (Shyness 3) explores whether participants are able to complete this programme independently.

METHOD

A total of 98 individuals with social phobia were randomly assigned to a clinician-assisted computerized cognitive behavioural treatment (CaCCBT) group, a self-guided computerized CBT (CCBT) group, or to a waitlist control group. CaCCBT group participants completed the usual Shyness programme consisting of six online lessons, cognitive behavioural homework assignments, email contact with a therapist, and participation in an online discussion forum. CCBT group participants accessed the same resources except for therapist emails. An intention-to-treat model was used for data analyses.

RESULTS

A total of 77% of CaCCBT and 33% of CCBT group participants completed all lessons. Significant differences were found after treatment between CaCCBT and control groups (mean between-groups effect size (ES) for the social phobia measures=1.04), and between the CaCCBT and CCBT groups (mean between-groups ES for the social phobia measures=0.66). No significant differences were found after treatment between the CCBT and control groups (mean between-groups ES for the social phobia measures=0.38). CCBT participants, however, who completed the six lessons made good progress (mean within-group ES for the social phobia measures=0.62). Quantitative and qualitative data indicate that both the CaCCBT and CCBT procedures were acceptable to participants.

CONCLUSIONS

The reliability of this Internet-based treatment programme for social phobia has been confirmed. The therapist-guided condition was superior to the self-guided condition, but a subgroup of participants still benefited considerably from the latter. These data confirm that self-guided education or treatment programmes for common anxiety disorders can result in significant improvements.

Psychological characteristics of people with Parkinson's disease who prematurely drop out of professionally led Internet chat support groups

Researchers of Internet health interventions have begun to address the problems of high attrition rates. Attrition has been a problem for psychosocial interventions for nearly 50 years. It is ubiquitous no matter what the type of intervention or the modality of delivery. Consistent are the repeated findings that demographic characteristics are the most robust variables. We tested the hypothesis that the greater the fear and apprehension experienced in professionally led Internet support groups, the more likely the participants would not complete the 25-week intervention. The sample consisted of 66 people with Parkinson's disease; each participant was assigned to one of six chat groups. To assess psychological states, we used PCAD, a text analysis program analyzing each person's postings during each chat room session. There was a statistically significant difference between those who terminated the group early and those who completed the intervention on the Anxiety-Fear dimension, F=2.35, (6,63), p=0.03. People who dropped out demonstrated higher death and shame anxiety. A number of possible designs for online groups that may reduce premature attrition are discussed.

Adherence in Internet-based interventions

BACKGROUND

The Internet is a promising channel for delivering health-promoting interventions. A common problem for Internet-based interventions is low adherence. The current paper reports adherence rates from three different Internet-based trials with potential covariates.

METHODS

Data on adherence and baseline characteristics of users were collected from three different Internet-based trials: one supporting diabetes self-management, one supporting smoking cessation, and one offering an online personal health record. Logging of web use was used as the measure of adherence in two of the trials, while logging of authentication SMS messages was used in the third.

RESULTS

In all three trials, users dropped out at a high rate early in the intervention. The baseline variables that were related to use were self-efficacy, having smoking friends, age, gender, and education. Tailored emails increased use for up to five months into a one-year intervention.

CONCLUSION

Dropout from Internet-based trials is substantial, and attrition curves can be a valuable tool for more accurate pretrial estimates of sample size power. Automated follow-up of users via email seems likely to increase adherence and should be included in Internet-based interventions. Tailoring on baseline covariates to adherence such as self-efficacy could make them even more effective.

Design and implementation of an interactive website to support long-term maintenance of weight loss

Background

For most individuals, long-term maintenance of weight loss requires long-term, supportive intervention. Internet-based weight loss maintenance programs offer considerable potential for meeting this need. Careful design processes are required to maximize adherence and minimize attrition.

Objective

This paper describes the development, implementation and use of a Web-based intervention program designed to help those who have recently lost weight sustain their weight loss over 1 year.

Methods

The weight loss maintenance website was developed over a 1-year period by an interdisciplinary team of public health researchers, behavior change intervention experts, applications developers, and interface designers. Key interactive features of the final site include social support, self-monitoring, written guidelines for diet and physical activity, links to appropriate websites, supportive tools for behavior change, check-in accountability, tailored reinforcement messages, and problem solving and relapse prevention training. The weight loss maintenance program included a reminder system (automated email and telephone messages) that prompted participants to return to the website if they missed their check-in date. If there was no log-in response to the email and telephone automated prompts, a staff member called the participant. We tracked the proportion of participants with at least one log-in per month, and analyzed log-ins as a result of automated prompts.

Results

The mean age of the 348 participants enrolled in an ongoing randomized trial and assigned to use the website was 56 years; 63% were female, and 38% were African American. While weight loss data will not be available until mid-2008, website use remained high during the first year with over 80% of the participants still using the website during month 12. During the first 52 weeks, participants averaged 35 weeks with at least one log-in. Email and telephone prompts appear to be very effective at helping participants sustain ongoing website use.

Conclusions

Developing interactive websites is expensive, complex, and time consuming. We found that extensive paper prototyping well in advance of programming and a versatile product manager who could work with project staff at all levels of detail were essential to keeping the development process efficient.

Computer-aided psychotherapy: revolution or bubble?

Research into computer-aided psychotherapy is thriving around the world. Most of it concerns computer-aided cognitive-behavioural therapy (CCBT). A recent narrative review found 97 computer-aided psychotherapy systems from nine countries reported in 175 studies, of which 103 were randomised controlled trials. The rapid spread of the mass delivery of psychotherapy through CCBT, catalysed in the UK by the National Institute for Health and Clinical Excellence's recommendation of two CCBT programmes and the Department of Health's CCBT implementation guidance, seems unprecedented. This editorial is a synopsis of the current status of CCBT and its future directions.

Following up nonrespondents to an online weight management intervention: randomized trial comparing mail versus telephone

Background

Attrition, or dropout, is a problem faced by many online health interventions, potentially threatening the inferential value of online randomized controlled trials.

Objective

In the context of a randomized controlled trial of an online weight management intervention, where 85% of the baseline participants were lost to follow-up at the 12-month measurement, the objective was to examine the effect of nonresponse on key outcomes and explore ways to reduce attrition in follow-up surveys.

Methods

A sample of 700 nonrespondents to the 12-month online follow-up survey was randomly assigned to a mail or telephone nonresponse follow-up survey. We examined response rates in the two groups, costs of follow-up, reasons for nonresponse, and mode effects. We ran several logistic regression models, predicting response or nonresponse to the 12-month online survey as well as predicting response or nonresponse to the follow-up survey.

Results

We analyzed 210 follow-up respondents in the mail and 170 in the telephone group. Response rates of 59% and 55% were obtained for the telephone and mail nonresponse follow-up surveys, respectively. A total of 197 respondents (51.8%) gave reasons related to technical issues or email as a means of communication, with older people more likely to give technical reasons for noncompletion; 144 (37.9%) gave reasons related to the intervention or the survey itself. Mail follow-up was substantially cheaper: We estimate that the telephone survey cost about US $34 per sampled case, compared to US $15 for the mail survey. The telephone responses were subject to possible social desirability effects, with the telephone respondents reporting significantly greater weight loss than the mail respondents. The respondents to the nonresponse follow-up did not differ significantly from the 12-month online respondents on key outcome variables.

Conclusions

Mail is an effective way to reduce attrition to online surveys, while telephone follow-up might lead to overestimating the weight loss for both the treatment and control groups. Nonresponse bias does not appear to be a significant factor in the conclusions drawn from the randomized controlled trial.

Status of computerized cognitive behavioural therapy for adults

A growing body of evidence supports the efficacy of computerized cognitive behavioural therapy (CCBT). This technology has the potential to increase the capacity of mental health services, and to overcome some of the barriers to accessing mental health services, including stigma, traveling time for rural patients, treatment delays, and the low availability of skilled clinicians. This review discusses key issues around the implementation of CCBT in current mental health services, and summarizes recent evidence for the efficacy of CCBT in anxiety and depression. Many CCBT systems exist, and the evidence for each varies in quality and quantity. It is concluded that CCBT, particularly guided by a therapist, represents a promising resource. However, considerable work needs to be done to develop CCBT techniques that are appropriate to Australasian populations, acceptable to patients and clinicians, easy to use, and are clinically and cost effective. Suggestions are made for further research and useful website addresses are provided to assist clinicians in familiarizing themselves with CCBT.

Using Computers to Improve the Psychosocial Care of Implantable Cardioverter Defibrillator Recipients

Person-to-person psychosocial interventions (e.g., psychological, social) enhance the well-being of implantable cardioverter defibrillator (ICD) patients. Computerized care, though, represents an opportunity to further capitalize on techniques that have already been deemed effective. This includes the provision of tailored, effective patient education; reducing device-specific anxiety; and enhancing social support networks. The aim of this paper is to identify the ways in which computerized psychosocial care could potentially enhance the well-being of ICD recipients. For example, computers may be particularly adept at providing patient education due to the ease in which content can be adapted to meet patient needs. Further, evidenced-based treatments for anxiety and depression (e.g., cognitive behavioral therapy) have demonstrated good applicability to computerized formats. Social support can also be provided online in the form of bulletin boards, email list-servs, or structured online support groups. Despite the existence of some limitations, the use of computers in affecting psychosocial outcomes in implantable defibrillator recipients warrants greater attention.

Using the Internet to enhance the treatment of depression

OBJECTIVE

Deficiencies in Australia's mental health systems persist despite over a decade of mental health reform. Recent developments in e-health provide the opportunity to facilitate health reform and improve services. This paper presents preliminary findings from the implementation of a comprehensive e-health system, called RecoveryRoad, which was designed to augment the routine clinical treatment of depression.

METHODS

Depressed patients (n = 144) were referred to RecoveryRoad from a public hospital and public and private clinics in Perth, Western Australia. Online features included secure e-consultations, progress monitoring questionnaires, psychoeducation and evidence-based therapy. Treating clinicians had online access to patients' progress monitoring outcomes and e-consultations. There were two types of adherence reminders: automated email reminders and personalized case management delivered by email and telephone.

RESULTS

Adherence to the system was high (from 53% to 84%, depending on the modality of reminder), and self-reported medication adherence was over 90%. Average depression severity declined from severe to mild by the eighth session, a large effect (d = 1.0). Both clinicians and patients were generally satisfied with the programme and reported that it improved clinician-patient relationships. Clinicians also reported that it helped patients to better manage depression.

CONCLUSIONS

Preliminary findings support the feasibility of comprehensive e-health systems in enhancing the delivery of mental health care.

Tailored program evaluation: Past, present, future

This paper discusses measurement issues related to the evaluation of computer-tailored health behavior change programs. As the first generation of commercially available tailored products is utilized in health promotion programming, programmers and researchers are becoming aware of the unique challenges that the evaluation of these programs presents. A project is presented that used an online tailored health behavior assessment (HBA) in a worksite setting. Process and outcome evaluation methods are described and include the challenges faced, and strategies proposed and implemented, for meeting them. Implications for future research in tailored program development, implementation, and evaluation are also discussed.

Self-help treatments for disorders of recurrent binge eating: a systematic review

OBJECTIVE

To evaluate self-help interventions for patients with binge eating disorder (BED) and bulimia nervosa (BN), tested in randomized controlled trials, and compared with waiting list or any other type of control group.

METHODS

A systematic review including quality appraisal was conducted of randomized controlled trials, using self-help techniques in patients with BED and/or BN. Six databases were searched during the period between January 1994 and June 2004.

RESULTS

A total of 2686 articles were identified, 1701 abstracts were evaluated in detail and, nine studies fulfilled the inclusion criteria for this review. All studies indicated that patients treated with active interventions had a reduced number of binge eating episodes at end of treatment.

CONCLUSION

The results support self-help interventions but shall be interpreted with caution. Because of the small number of studies using self-help techniques for BED and BN, further larger randomized, multi-center controlled studies that apply standardized inclusion criteria, evaluation instruments and self-help materials, are needed.

Case management and adherence to an online disease management system

Non-adherence to treatment presents a significant obstacle to achieving favourable health outcomes. We have studied consumers' adherence to an online disease management system for depression, called Recovery Road. Recovery Road was implemented on a pilot basis for mental health care in Western Australia. Recovery Road was available for use by consumers and clinicians to augment usual treatment. One hundred and thirty consumers who had been diagnosed with major depression were enrolled. Consumers who used Recovery Road (n = 98) were provided with education, progress monitoring, e-consultation, e-diary and online evidenced-based therapy. Consumers received either standard, automated adherence reminders by email (n = 69), or case management, which included personalized email and telephone follow-up in response to non-adherence (n = 29). After the first eight sessions, the adherence was 84% in the case management group and 55% in the automatic reminders group. The results suggest that case management increases adherence to online disease management systems.

Self-help Internet interventions for mental disorders

PURPOSE OF REVIEW

In recent years a considerable number of publications has appeared on various aspects of Internet interventions for mental health care. The purpose of the present article is to review the current scientific status of Internet interventions for the treatment of mental disorders.

RECENT FINDINGS

Randomized controlled studies on the use Internet interventions for the treatment of mental disorders are still scarce. Most studies in the field have been on Internet interventions for the treatment of depressive disorders and anxiety disorders, using cognitive behavioural therapy. In addition, a few studies have been published on the use of Internet interventions in the treatment of substance use disorders (smoking, problem drinking), insomnia and tinnitus.

SUMMARY

Recent studies provide provisional evidence that Internet interventions may be a promising tool for the treatment of some mental disorders.

The law of attrition

In an ongoing effort of this Journal to develop and further the theories, models, and best practices around eHealth research, this paper argues for the need for a “science of attrition”, that is, a need to develop models for discontinuation of eHealth applications and the related phenomenon of participants dropping out of eHealth trials. What I call “law of attrition” here is the observation that in any eHealth trial a substantial proportion of users drop out before completion or stop using the appplication. This feature of eHealth trials is a distinct characteristic compared to, for example, drug trials. The traditional clinical trial and evidence-based medicine paradigm stipulates that high dropout rates make trials less believable. Consequently eHealth researchers tend to gloss over high dropout rates, or not to publish their study results at all, as they see their studies as failures. However, for many eHealth trials, in particular those conducted on the Internet and in particular with self-help applications, high dropout rates may be a natural and typical feature. Usage metrics and determinants of attrition should be highlighted, measured, analyzed, and discussed. This also includes analyzing and reporting the characteristics of the subpopulation for which the application eventually “works”, ie, those who stay in the trial and use it. For the question of what works and what does not, such attrition measures are as important to report as pure efficacy measures from intention-to-treat (ITT) analyses. In cases of high dropout rates efficacy measures underestimate the impact of an application on a population which continues to use it. Methods of analyzing attrition curves can be drawn from survival analysis methods, eg, the Kaplan-Meier analysis and proportional hazards regression analysis (Cox model). Measures to be reported include the relative risk of dropping out or of stopping the use of an application, as well as a “usage half-life”, and models reporting demographic and other factors predicting usage discontinuation in a population. Differential dropout or usage rates between two interventions could be a standard metric for the “usability efficacy” of a system. A “run-in and withdrawal” trial design is suggested as a methodological innovation for Internet-based trials with a high number of initial dropouts/nonusers and a stable group of hardcore users.
