Evaluation of additional resources used in therapist-assisted transdiagnostic internet-delivered cognitive behaviour therapy.

Background: In internet-delivered cognitive behavioural therapy (ICBT) programs, beyond standardized core ICBT lessons, brief additional resources are sometimes available to clients to address comorbid concerns or offer additional information/strategies. These resources remain understudied in terms of how they are selected and perceived by clients, as well as their relationship to satisfaction and outcomes. Methods: Among clients (N = 793) enrolled in a 5-lesson transdiagnostic ICBT course, we examined client use and perceptions of 18 additional resources at 8 weeks in terms of whether clients found resources informative (yes/no) and or helpful (yes/no). Resources elaborated on cognitive strategies (managing beliefs, risk calculation) or on managing specific problems (agricultural stress, alcohol misuse, anger, assertiveness, chronic conditions, communication, grief, health anxiety, motivation, pain, panic, postpartum depression/anxiety, PTSD, sleep, workplace accomodations, worry). Clients also completed symptom measures and ICBT satisfaction questions at 8 weeks. Results: Approximately 50 % (n = 398) of clients rated the resources and, on average, clients reported that 3.35 (SD = 3.34) resources were informative and 2.35 (SD = 2.52) resources were helpful as measured by direct questions developed for this study. Higher pre-treatment PTSD and GAD scores were related to a greater number of resources perceived as informative and or helpful. Rating more resources as informative and or helpful had a weak but positive association with ICBT satisfaction and depression, anxiety, PTSD and insomnia change scores. Limitations of the study include that 31 % (n = 245) did not respond to questions about use of resources and 18.9 % (n = 150) said they did not review resources. Conclusions: There is considerable use of diverse additional resources in ICBT in routine care. Associations suggest that clients are using resources to personalize treatment to their needs and these resources are associated with treatment satisfaction and outcomes. The correlational associations between symptoms and perceived helpfulness of resources can help inform personalization algorithms to optimize ICBT delivery for clients. Further research on how to match clients with, encourage use of, and maximize benefits of resources would be beneficial.

Treating comorbid insomnia in patients enrolled in therapist-assisted transdiagnostic internet-delivered cognitive behaviour therapy for anxiety and depression: A randomized controlled trial.

Transdiagnostic Internet-delivered cognitive behaviour therapy (ICBT) for patients experiencing anxiety and depression can produce large improvements in symptoms. Comorbid insomnia is common among individuals seeking treatment for anxiety and depression, yet transdiagnostic ICBT rarely targets insomnia and many ICBT patients report that symptoms of insomnia remain after treatment. This trial explored the impact of including a brief intervention for insomnia alongside an existing transdiagnostic ICBT course that included brief weekly therapist assistance. Patients were randomly assigned to receive either the Standard transdiagnostic (n = 75) or a Sleep-Enhanced course (n = 142), which included information on sleep restriction and stimulus control. Intent-to-treat analyses using generalized estimating equation (GEE) showed significant, large reductions in all primary outcomes (insomnia: d = 0.96, 95 % CI [0.68, 1.24]; depression: d = 1.04, 95 % CI [0.76, 1.33]; and anxiety: d = 1.23, 95 % CI [0.94, 1.52]) from pre-treatment to post-treatment, with changes maintained at 3-months. Patients assigned to the Sleep-Enhanced course reported larger reductions in insomnia than patients in the Standard transdiagnostic course (Cohen's d = 0.31, 95 % CI [0.034, 0.60]) at post-treatment but no significant between-group differences in any of the primary outcomes were found at follow-up. Patient-reported adherence to sleep restriction guidelines (p = .03), but not stimulus control instructions (p = .84) was associated with greater reductions in insomnia symptoms during the course. Overall, patients who received the Sleep-Enhanced course were satisfied with the materials and most patients reported making sleep behaviour changes. The trial results demonstrate that including a brief intervention targeting insomnia can be beneficial for many patients who enroll in ICBT primarily for symptoms related to anxiety and depression.

Acceptability and effectiveness study of therapist-assisted internet-delivered cognitive behaviour therapy for agriculture producers.

Agriculture producers are less likely to seek or to receive mental health services compared to the general population. Additional research is needed to identify effective and accessible mental health interventions for this underserved population. This study used a mixed-methods approach and open trial design to examine the acceptability and effectiveness of therapist-assisted internet-delivered cognitive behaviour therapy (ICBT) supplemented with an additional agricultural resource for clients from agricultural backgrounds receiving ICBT in routine care. Clients (n = 34) participated in an online, five-lesson course that provided psychoeducation and strategies for dealing with symptoms of anxiety and depression, with weekly therapist assistance. Clients also received a tailored resource (developed with input from those with an agricultural background) providing culturally specific information and case stories pertinent to agricultural communities. Intent-to-treat analyses showed that the ICBT program was effective in reducing anxiety and depression symptoms among the agricultural population. Large within-group pre-to-post-treatment Cohen's effect sizes of d = 1.14, 95 % CI [0.41, 1.86] and d = 1.15, 95 % CI [0.42, 1.87] were found for depression and anxiety, respectively and comparable to the same program offered to the general population. Clients also experienced reductions in perceived stress and significant improvements in resiliency from pre- to post-treatment. Semi-structured interviews conducted at post-treatment with the agricultural clients (n = 31) on their experiences with ICBT identified four main themes: perceived strengths of ICBT and the tailored resource, suggestions to improve service delivery for agriculture producers, clients experienced internal and external challenges to participating in ICBT, and the positive impact of the course reached beyond the client. Very high satisfaction rates were found. These results provide support for the acceptability and effectiveness of ICBT with a tailored resource offered in routine care among agriculture producers.

Cost-effectiveness of varying degrees and models of therapist-assisted transdiagnostic internet-delivered cognitive behaviour therapy: Evidence from a randomized controlled trial.

In routine care, Internet-delivered Cognitive Behaviour Therapy (ICBT) is often delivered with therapist support via emails/phone calls, but the cost-effectiveness of varying amounts of therapist support or having therapists specialized in ICBT is not known. This study compared the cost-effectiveness of specialized therapists providing ICBT support once-weekly (1WS) versus providing support once-weekly supplemented with a one-business-day response to patient emails (1W/1BD-S). We further compared the cost-effectiveness of 1W support offered by therapists employed in a specialized clinic (1WS) versus community clinics where therapists primarily deliver face-to-face therapy (1WC). Patients were randomly allocated to groups: 1WS group (n = 216), 1W/1BD-S group (n = 233), and 1WC group (n = 226). At baseline, 12, 24 and 52-week follow-up, patients completed the Treatment Inventory of Costs in Patients with Psychiatric Disorders questionnaire (TiC-P) adapted for use in Canada to assess healthcare use and productivity losses. Additionally, to assess Quality Adjusted Life Years (QALYs) gained, patients completed the EQ-5D-5L at the same time periods. We quantified uncertainties by one-way and probabilistic sensitivity analysis and reported Incremental cost-effectiveness ratios (ICER), cost-effectiveness planes and acceptability curves. Cost-effectiveness over 52 weeks was CAD 3072/QALY for 1WC, CAD 3244/QALY for 1W/1BD-S, and CAD 3528/QALY for 1WS. Our model suggests that 1WS is the best strategy since the incremental cost per QALY is below the $50,000 threshold (ICER is CAD 42,328/QALY compared to the next most effective, 1WC). 1W/1BD-S is dominated by the other strategies. The cost-effectiveness acceptability curves suggest that the 1WS group has a higher probability for cost-effectiveness (38 %) than 1W/1BD-S (30 %) and 1WC (32 %) when the willingness to pay is $50,000 per QALY. These results have important implications for health policymakers deciding on delivery of ICBT for the treatment of anxiety and/depressive disorders.

Internet-delivered cognitive behaviour therapy for chronic health conditions: self-guided versus team-guided.

There is growing interest in offering Internet-delivered cognitive behaviour therapy (ICBT) to individuals with chronic health conditions, with this process often being guided by a single clinician. Due to lack of full time personnel, it is sometimes necessary to have multiple clinicians offer guidance or for no guidance to be offered. In this randomized trial, we compared team-guided ICBT (n = 90) to self-guided ICBT (n = 88). Participants completed measures at pre-, post-, and 3-months post-ICBT. Both groups showed similar rates of treatment completion and large improvements on depression and anxiety at post-treatment and follow-up. Unexpectedly, more participants in the self-guided versus team-guided condition showed clinically significant improvement on depression at post-treatment (76.5% vs 49.2%) and follow-up (70% vs 45.6%). Thus, team-guided ICBT may not provide significant benefits compared to self-guided ICBT. However, it may be an alternative approach to consider among a population of high risk individuals that wants or requires closer monitoring of symptoms.Trail registration TRN: NCT03500237; Date: April 18, 2018.

A randomized factorial trial of internet-delivered cognitive behavioural therapy: An 8-week program with or without extended support and booster lesson.

While internet-delivered cognitive behavioural therapy (ICBT) is effective, some patients suggest extended support post-treatment could improve care. In this randomized factorial trial, we examined the benefits of an 8-week therapist-assisted ICBT program offered with or without an optional 4-week extension of support (Factor 1) and with or without an optional booster lesson (Factor 2). Patients screened for ICBT for depression and/or anxiety were randomly assigned to the conditions (N = 434) and we examined the use of the extension and booster, differences between those who did or did not use extension or booster, and the impact of the extension or booster on outcomes, engagement, and satisfaction at 26-weeks post-enrollment. Therapists recorded time and observations with offering support during the extension and booster. In the extension group, 54.4% (n = 56) requested the extension, while in the booster group 50.9% (n = 56) accessed the booster, and in the combined group, 41.6% (n = 47) requested the extension and 51.3% (n = 58) accessed the booster. Those who requested the extension were older, and more likely to report medication and mental health service use and severe mental health-related disability at pre-treatment; they also reported putting less effort into ICBT and finding skills more difficult. The booster was more often used among those with lower symptom severity, and those who put more effort into and had more positive experiences with ICBT. As expected, those assigned to extension sent more messages to their therapist, and those assigned to booster logged in more often. Therapists also took more time to deliver ICBT with an extension (>18 min) or booster (>13 min) compared to the 8-week program, and perceived extension and booster as beneficial for some, but not all patients. Treatment satisfaction was high across conditions, and effect sizes were large from pre-treatment to 26-week follow-up on most measures. No significant group differences were found in this study. Lack of group differences, however, could reflect low use of the extension and booster. Results provide helpful information about the demand for extensions and boosters, and provide directions for future research.

A pragmatic factorial randomized controlled trial of transdiagnostic internet-delivered cognitive behavioural therapy: Exploring benefits of homework reflection questionnaires and twice-weekly therapist support.

With the growing demand for internet-delivered cognitive behavioural therapy (iCBT), this pragmatic factorial (2 × 2 × 2) randomized controlled trial evaluated strategies for facilitating iCBT engagement and outcomes in routine care. Specifically, the benefits to patients and therapists of using homework reflection questionnaires and offering patients twice-weekly therapist support were examined. Patients (n = 632) accepted into iCBT for depression and/or anxiety were randomly assigned to complete homework reflection questionnaires or not (factor 1), receive once- or twice-weekly support (factor 2), and to receive care from therapists employed in one of two settings (iCBT clinic or a community mental health clinic; factor 3). Outcomes were measured at pre-treatment, and 8, 12, and 24-weeks post-enrollment. Therapist time was tracked and a focus group was conducted to examine therapist experiences. No differences in patient outcomes were found between therapists employed in the two settings; as such, these two groups were combined for further analyses. In terms of engagement, homework reflection questionnaires were associated with fewer website log-ins and days accessing iCBT; twice-weekly support was associated with more patient emails sent to therapists. Despite engagement differences, homework reflection questionnaires and twice-weekly support did not significantly impact primary outcomes; all groups showed large improvements in depression and anxiety that were maintained at 24-week follow-up. Therapists perceived a number of benefits and challenges associated with responding to homework reflection questionnaires and offering twice-weekly support; most notably the strategies did not benefit all patients. Twice-weekly support was associated with increased therapist time and organizational challenges. It is concluded that neither completion of homework questionnaires nor offering twice-weekly support significantly improve iCBT in routine care.

Transdiagnostic Internet-delivered cognitive behaviour therapy with therapist support offered once-weekly or once-weekly supplemented with therapist support within one-business-day: Pragmatic randomized controlled trial.

In routine care, internet-delivered cognitive behaviour therapy (iCBT) regularly includes therapist support delivered via secure email, but the optimal response time to emails is unknown. In this study, we compared the benefits of therapists providing support once-weekly versus therapists providing support once-weekly supplemented with a one-business-day response to all patient emails. This pragmatic randomized controlled trial included therapists employed by a specialized iCBT clinic or community mental health clinics, where providing iCBT is a secondary service. Patients with depression and/or anxiety who enrolled in transdiagnostic iCBT (5 core lessons over 8 weeks) were randomized to: 1) once-weekly support supplemented with a one-business-day response to patient emails by specialized therapists (n = 233); 2) once-weekly support also offered by specialized therapists (n = 216); or 3) once-weekly support offered by community clinic therapists (n = 226). Outcomes were measured at 8, 12, 24, and 52-weeks post-enrollment. Patient engagement and treatment experiences (e.g., treatment satisfaction, therapist alliance) were also assessed and a focus group was conducted with therapists. Supplementing once-weekly therapist support with a one-business-day response to patient emails resulted in therapists sending more emails to patients (M: 13 versus 9) and required more therapist time over treatment (M: 155 versus 109 min), but was not associated with improved outcomes, patient engagement or treatment experiences. All groups showed large improvements in symptoms of depression and anxiety maintained at 52-week follow-up, strong engagement and positive treatment experiences. Therapists viewed challenges of responding to patient emails within one-business-day to outweigh benefits. Contrary to expectations, supplementing once-weekly therapist support with a one-business-day response to all patient emails did not benefit patients and increased therapist time as well as therapist challenges when delivering iCBT in routine care.

Efficacy of internet-delivered cognitive behavioural therapy following an acute coronary event: A randomized controlled trial.

Depression and anxiety are common among people who have experienced an acute coronary event (e.g., heart attack). Multidisciplinary cardiac rehabilitation programs often focus on reducing risk factors associated with future cardiac events, however, mental health interventions are not routinely available. Given known difficulties with access to mental health treatment, the present study sought to explore the efficacy and acceptability of an Internet-delivered cognitive behavioural therapy program (Cardiac Wellbeing Course) among participants who experienced an acute coronary event. The five-lesson course was delivered over eight weeks and was provided with brief weekly contact, via telephone and secure email with a guide. Participants were randomized to the Cardiac Wellbeing Course (n = 25) or waiting-list control group (n = 28). Symptoms were assessed at pre-treatment, post-treatment, and four-week follow-up. Completion rates (84%) and satisfaction ratings (95%) were high. Statistically significant between-group improvements were observed for the treatment group on primary measures of general anxiety (Cohen's d = 1.62; 67% reduction), depression (Cohen's d = 1.09; 61% reduction), and physical activity levels (Cohen's d = 0.27; 70% increase). Statistically significant improvements were also observed on secondary measures of distress (Cohen's d = 0.98; 51% reduction), cardiac anxiety (Cohen's d = 0.92; 34% reduction), and mental-health quality of life (Cohen's d = 0.23; 24% improvement). The changes were maintained at four-week follow-up. The current findings add to the existing literature and highlight the potential of Internet-delivered cognitive behavioural therapy programs among participants who have experienced an acute coronary event.

Making Internet-delivered cognitive behaviour therapy scalable for cancer survivors: a randomized non-inferiority trial of self-guided and technician-guided therapy.

PURPOSE: To compare the effectiveness and acceptability of two low-intensity methods of offering a transdiagnostic Internet-delivered cognitive behaviour therapy (ICBT) intervention for treating symptoms of anxiety and depression among cancer survivors. METHODS: Cancer survivors with symptoms of anxiety or depression (n = 86) were randomly assigned to receive a transdiagnostic ICBT programme (Wellbeing After Cancer) that was either guided by a technician (n = 42) or self-guided (n = 44). Measures of anxiety, depression, fear of cancer recurrence, and quality of life were completed at pre-treatment, post-treatment, and 4 weeks following treatment completion. RESULTS: Large within-group effect sizes were observed on measures of depression, anxiety, and mental health-related quality of life (d range, 0.98-1.86) at post-treatment. Medium effects were found for reductions in fear of cancer recurrence (d range, 0.65-0.78). Non-inferiority was established for the primary outcome measures of anxiety and depression. All participants reported high satisfaction ratings of the programme; however, technician-guided participants were slightly more satisfied with their level of support (d = 0.57, p = .014). CONCLUSIONS: The Wellbeing After Cancer Course was associated with improved levels of anxiety, depression, fear of cancer recurrence, and quality of life, regardless of how ICBT was offered. IMPLICATIONS FOR CANCER SURVIVORS: ICBT is emerging as an accessible and effective treatment for depression, anxiety, and fear of cancer recurrence in cancer survivors. The success of non-therapist-guided options increases the potential scalability of ICBT, which is particularly valuable for cancer survivors from rural areas who have less access to mental health services.

Preference trial of internet-delivered cognitive behaviour therapy comparing standard weekly versus optional weekly therapist support.

Emerging evidence from research trials suggests that Internet-delivered cognitive behaviour therapy (ICBT) produces similar symptom improvements whether patients receive weekly therapist support (standard support) or therapist support only when requested (optional support). It remains unknown, however, how many patients receiving ICBT as part of routine clinical care would prefer optional support compared to standard support and how outcomes compare when patients select their preferred treatment option. In this uncontrolled trial, we investigated patient preference and outcomes for standard versus optional support among patients with depression and or anxiety who were offered an 8-week transdiagnostic ICBT intervention in routine care. Of 401 patients accepted for ICBT, 22% selected optional support and 78% selected standard support. At assessment, patients who selected optional support had lower symptoms of anxiety and panic than patients who selected standard support. At post-treatment, both groups achieved similar large improvements in symptoms of anxiety and depression, with improvements sustained at 3-month follow-up. Patients receiving optional support sent and received fewer messages compared to patients receiving standard support. This study demonstrates the potential of optional therapist support to meet the needs and preferences of patients and to also reduce therapist costs in routine care.

The Pain Course: exploring the feasibility of an internet-delivered pain management programme for adults with spinal cord injury.

STUDY DESIGN: Single-group feasibility clinical trial. OBJECTIVES: This study examined the feasibility and outcomes of a modified version of a validated internet-delivered pain management programme, the Pain Course, for adults with SCI. SETTING: Nationwide in Australia. METHODS: Sixty-eight adults participated in the programme, which comprises five online lessons and homework tasks that are systematically released over 8 weeks. Participants were supported through the course with weekly contact from a clinical psychologist. RESULTS: Eighty-five percent of participants provided data at post-treatment and 76% of participants completed all five lessons of the course. High levels of satisfaction were observed and relatively little clinician time (M = 93.16 min; SD = 52.76 min) was required per participant to provide the course. Preliminary evidence of clinical improvements in pain-related disability (ds ≥ 0.53.; avg. improvement ≥ 20%; Mdiff ≥ 7.77), depression (ds ≥ 0.44.; avg. improvement ≥ 24%; Mdiff ≥ 2.44), anxiety (ds ≥ 0.41.; avg. improvement ≥ 26%; Mdiff ≥ 1.8) and average pain intensity (ds ≥ 0.46.; avg. improvement ≥ 13%; Mdiff ≥ 0.71) were observed at post-treatment, which were maintained or further improved to 3-month follow-up. These improvements were reflected in overall improvements in self-reported satisfaction with life (ds ≥ 0.31; avg. improvement ≥ 25%; Mdiff ≥ 2.16) CONCLUSION: These findings highlight the potential of carefully developed internet-delivered interventions as an approach for overcoming barriers and increasing access to psychosocial care for adults with SCI.

Patient Perspectives on Strengths and Challenges of Therapist-Assisted Internet-Delivered Cognitive Behaviour Therapy: Using the Patient Voice to Improve Care.

Therapist-assisted internet-delivered cognitive behaviour therapy (T-ICBT) involves patients reading online treatment materials, completing relevant exercises, and receiving therapist support. This study aimed to understand the preferences and recommendations of 225 patients enrolled in a T-ICBT course for depression and anxiety via an online therapy unit in collaboration with community mental health clinics dispersed across one Canadian province. An open-ended survey asked participants their opinions of the course and responses were analyzed using a content analysis approach. Patient comments addressed many strengths of the course (64%), with some opportunities for improvement (36%). Most-appreciated features included ability to download content for future use, reading other patients' experiences, and content of lessons. Patients made suggestions for improving the breadth of patient stories, timeline of the course, and matching availability of the therapist to patient need. Patient feedback regarding preferences provides valuable information for improving the patient-centered nature of T-ICBT.

Exploring psychological mechanisms of clinical response to an internet-delivered psychological pain management program.

BACKGROUND: The evidence for Internet-delivered pain management programs for chronic pain is growing, but there is little empirical understanding of how they effect change. Understanding mechanisms of clinical response to these programs could inform their effective development and delivery. METHODS: A large sample (n = 396) from a previous randomized controlled trial of a validated internet-delivered psychological pain management program, the Pain Course, was used to examine the influence of three potential psychological mechanisms (pain acceptance, pain self-efficacy, fear of movement/re-injury) on treatment-related change in disability, depression, anxiety and average pain. Analyses involved generalized estimating equation models for clinical outcomes that adjusted for co-occurring change in psychological variables. This was paired with cross-lagged analysis to assess for evidence of causality. Analyses involved two time points, pre-treatment and post-treatment. RESULTS: Changes in pain-acceptance were strongly associated with changes in three (depression, anxiety and average pain) of the four clinical outcomes. Changes in self-efficacy were also strongly associated with two (anxiety and average pain) clinical outcomes. These findings suggest that participants were unlikely to improve in these clinical outcomes without also experiencing increases in their pain self-efficacy and pain acceptance. However, there was no clear evidence from cross-lagged analyses to currently support these psychological variables as direct mechanisms of clinical improvements. There was only statistical evidence to suggest higher levels of self-efficacy moderated improvements in depression. CONCLUSIONS: The findings suggest that, while clinical improvements are closely associated with improvements in pain acceptance and self-efficacy, these psychological variables may not drive the treatment effects observed. SIGNIFICANCE: This study employed robust statistical techniques to assess the psychological mechanisms of an established internet-delivered pain management program. While clinical improvements (e.g. depression, anxiety, pain) were closely associated with improvements in psychological variables (e.g. pain self-efficacy and pain acceptance), these variables do not appear to be treatment mechanisms.

Transdiagnostic internet-delivered cognitive-behaviour therapy (CBT) for adults with functional gastrointestinal disorders (FGID): A feasibility open trial.

Many people with functional gastrointestinal disorders (FGIDs) face significant barriers in accessing psychological treatments that are known to reduce symptoms and their psychological sequelae. This study examined the feasibility and initial outcomes of a transdiagnostic and internet-delivered cognitive behaviour therapy (iCBT) intervention, the Chronic Conditions Course, for adults with functional gastrointestinal disorders (FGIDs). A single-group feasibility open trial design was employed and administered to twenty seven participants. The course ran for 8 weeks and was provided with weekly contact from a Clinical Psychologist. Seventy percent of participants completed the course within the 8 weeks and 81.5% provided data at post-treatment. High levels of satisfaction were observed and relatively little clinician time (M = 42.70 min per participant; SD = 46.25 min) was required. Evidence of clinical improvements in FGID symptoms (ds ≥ 0.46; avg. improvement ≥21%), anxiety symptoms (ds ≥ 0.99; avg. improvement ≥42%), and depression symptoms (ds ≥ 0.75; avg. improvement ≥35%) were observed, which either maintained or continued to improve to 3-month follow-up. Evidence of improvement was also observed in pain catastrophising and mental-health related quality of life, but not physical-health related quality of life. These findings highlight the potential value of transdiagnostic internet-delivered programs for adults with FGIDs and support for the conduct of larger-scale controlled studies.

Who benefits most from therapist-assisted internet-delivered cognitive behaviour therapy in clinical practice? Predictors of symptom change and dropout.

Internet-delivered cognitive behavioral therapy (ICBT) is effective for treating anxiety and depression, but not for all patients. Predictors of dropout and outcomes from ICBT remain unclear and the literature could benefit from study of response to ICBT among larger community samples using advanced statistical techniques. In this study, we sought to identify predictors of dropout and symptom change in a large community sample (n = 1201) who received therapist-assisted transdiagnostic ICBT targeting anxiety and/or depression. Logistic regression was used to assess dropout, and showed that those who fully completed ICBT lessons (n = 880) were older and endorsed lower psychological distress at intake than those who only partially completed ICBT lessons (n = 321). During the course of therapy, patients responded to the Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 at six time points. Autoregressive latent trajectory models were fitted to this data to assess the ability of demographic variables, program engagement, psychological and medical service usage, and psychological distress to explain individual variance in initial symptom levels and symptom change over time. Higher symptom scores at pre-treatment were predictive of greater symptom improvement. Symptom improvement was greater in those who were off work on disability and those without higher post-secondary education. Clinical implications are discussed.

Randomized controlled trial of internet-delivered cognitive behaviour therapy comparing standard weekly versus optional weekly therapist support.

Internet-delivered cognitive behaviour therapy (ICBT) is effective for treating anxiety and depression. The relative benefits of offering standard weekly compared to optional weekly therapist support in conjunction with ICBT within routine care has not been examined. Patients seeking ICBT for depression and or anxiety in routine care were randomized to standard (n=92) or optional (n=88) weekly support. The optional approach resulted in therapists receiving half as many messages from (1.70 vs. 3.96) and sending half as many messages to patients (3.62 vs. 7.29). Optional Support was associated with lower completion rates (56.6% versus 82.4%), but, similar to Standard Support, resulted in large reductions on the GAD-7 (within Cohen's d≥1.08; avg. reduction ≥47%) and PHQ-9 (within Cohen's d≥0.82; avg. reduction ≥43%) at post-treatment and 3-month follow-up. Optional weekly support appears clinically effective and acceptable for many patients and may reduce costs, but safety requires monitoring given lower completion rates.

The pain course: a randomised controlled trial comparing a remote-delivered chronic pain management program when provided in online and workbook formats.

This study compared a remote-delivered pain management program, the Pain Course, when delivered in online and workbook formats. Participants (n = 178) were randomised into 2 groups: (1) an Internet Group (n = 84) who were provided with secure accounts to the program in an online format; or (2) a Workbook Group (n = 94) who were mailed workbook versions of the program. The content of both programs was identical and comprised 5 core lessons, which participants were encouraged to work through over an 8-week period, according to a prescribed timetable. All participants were provided with weekly contact with a clinical psychologist through email and telephone throughout the program. The overall findings suggest that the workbook format was no less effective or acceptable than the validated online format. Significant improvements (avg. improvement; Internet Group vs Workbook Group) in levels of disability (PDI: 16% vs 24%; RMDQ: 12% vs 15%), anxiety (GAD-7: 36% vs 26%), and depression (PHQ-9: 36% vs 36%) were observed in both groups immediately posttreatment. Further improvements were observed in disability levels to 3-month follow-up, and improvements across the other primary outcomes were maintained until 12-month follow-up. High treatment completion rates and levels of satisfaction were reported in both groups, and both groups required a similarly small amount of clinician contact per participant (M = 74.85 minutes; SD = 41.03). These results highlight the public health potential of remote-delivered pain management programs, delivered in either workbook or online formats, as methods of increasing access to pain management.

Rumination induces a pattern of attention characterized by increased vigilance followed by avoidance of affective pain words.

BACKGROUND: This study examined the effects of rumination on attentional processes in relation to an acute experimental pain task. In keeping with recent theory and research, it was hypothesized that we would identify a pattern of attentional bias characterized by enhanced initial vigilance followed by avoidance of pain-related stimuli. METHOD: Undergraduate students were randomized to a rumination condition, which received threat-inducing information about the cold pressor task, or a distraction condition. Using the dot probe task, attentional biases to sensory and affective pain words were assessed at two presentation intervals (500 and 1250 ms). RESULTS: Those in the rumination condition did not show differences in attentional biases compared to the control group, however, they did respond more quickly to pain congruent trials compared to neutral/neutral trials when affective pain words were presented for 500 ms. In addition, those in the rumination group responded more slowly in congruent trials to neutral/neutral trials than affective/neutral trials indicating avoidance at 1250 ms. Although those in the rumination condition exhibited higher levels of distress and reported higher levels of pain when they withdrew their hands from the cold pressor task, the congruency biases did not predict these results. CONCLUSION: These results suggest that experimentally manipulating rumination changes attentional processes consistent with the vigilance-avoidance hypothesis. SIGNIFICANCE: The rumination manipulation led to increased worry about pain and induced to an attentional pattern of vigilance-avoidance for affective pain words. The induction also led to more distress and pain. Rumination and worry appear to increase unhelpful patterns of attention and could be an appropriate focus of intervention.
