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.

Assistência fisioterapêutica a indivíduos com Acidente Vascular Encefálico residentes na comunidade na atenção básica no Brasil: um estudo transversal

ABSTRACT After hospital discharge, it is recommended that post-stroke individuals receive follow-up by a physical therapist throughout all the stages of recovery. Despite clinical recommendations, few studies have investigated physical therapy care to community-dwelling individuals with stroke. This study aimed to describe physical therapy care to community-dwelling individuals with stroke in primary care setting and identify clinical-functional and sociodemographic characteristics that determined physical therapy assistance. This is an exploratory cross-sectional study. Community-dwelling individuals with stroke who were assisted by the primary healthcare team from an important Brazilian metropolis were included. Their medical records were analyzed to identify the care provided by physical therapists. Individuals who received and did not receive physical therapy care were compared (α=0.05). Out of the 100 included individuals, 55% received assistance from the multidisciplinary primary healthcare team and 44% from physical therapists. Physical therapy approaches consisted mainly of general orientations (89%) and assessments (75%). Only 45% of the individuals who received physical therapy care were followed-up, and those who received this type of care had significantly more stroke events and higher levels of disability (p<0.001). It was observed that many individuals with various levels of disabilities have not received physical therapist assistance. Moreover, follow-up care and referrals were not frequent physical therapy approaches. Therefore, physical therapy care in primary care needs to be expanded to ensure that all individuals with some level of disability receive treatment. Moreover, it is necessary to increase the number of individuals receiving follow-up and encourage multidisciplinary work between physical therapists and other primary healthcare professionals.

Relative Efficacy of Self-directed and Therapist-assisted Telehealth Models of a Parent-mediated Intervention for Autism: Examining Effects on Parent Intervention Fidelity, Well-being, and Program Engagement.

Although there is growing interest in telehealth to deliver parent-mediated intervention for autistic children, empirical evaluations are limited, and little is known regarding the relative benefits of self-directed and therapist-assisted telehealth interventions. This study examined the effect of self-directed and therapist-assisted ImPACT Online on parent learning and well-being, moderators of treatment, and predictors of program engagement. Sixty-four young autistic children and their primary caregiver participated. Children were matched on age and developmental quotient and randomly assigned to a therapist-assisted, self-directed, or resource support control group. Participants were assessed at intake, after 6 months (post), and at a 3-month follow-up. There was a significant treatment effect for parent learning for the therapist-assisted but not self-directed program; when analysis was limited to parents who completed the program, treatment effects were observed for both groups. There were no treatment effects for parent self-efficacy or parenting stress; however, there was an effect on parents' perception of their child's positive impact. Parenting stress did not moderate the effect of group on parent outcomes. Parent age, program satisfaction, and therapist assistance were all significant predictors of parent program engagement. This study supports the efficacy of therapist-assisted telehealth parent-mediated intervention for teaching parents intervention strategies to support their child's social communication and improving their perceptions of their child's positive impact, and suggests that self-directed programs may be beneficial for parents who fully engage with the program.

Therapist training in video chat technology for use in an adaptive digital mental health intervention: Challenges, facilitators and implications for training models

AbstractObjectiveThis qualitative study investigated therapist training experiences, elements of skill acquisition, and barriers and facilitators associated with conducting assessments, and the delivery of low‐ and high‐intensity therapist assistance delivered via video chat technology, adjunctive to a transdiagnostic digital mental health intervention programme for anxiety and depression.MethodologyIn total, 34 semistructured interviews were conducted with 20 therapists. Twenty interviews explored experiences of training to administer a clinical assessment tool, and 14 additional interviews explored training experiences of delivering low‐ and high‐intensity therapist assistance via video chat technology.ResultsReflexive thematic analysis identified three themes: video chat skill acquisition, competencies transferrable to video chat and video chat service quality. Training and supervision were identified as important to scaffold skill development, and therapists described surprise that their skill set was transferrable to video chat. The most cited barrier to the adoption of video chat was the management of risk and distress, along with environmental suitability. Frequently cited facilitators to the adoption of video chat included stable Internet connection, protocols and resources.ConclusionThe benefits of video chat technology and digital mental health interventions can be maximised through the expansion and integration of training into existing teaching curricula. If therapists are familiarised and competent to deliver mental health services via the Internet, as well as in person, the future adoption of blended and stepped‐care models is likely to be increased.

Evaluation of Various Support Intensities of Digital Mental Health Treatment for Reducing Anxiety and Depression in Adults: Protocol for a Mixed Methods, Adaptive, Randomized Clinical Trial.

Anxiety and depression are leading causes of disease worldwide, requiring timely access to evidence-based treatment. Digital mental health (dMH) interventions increase accessibility to evidence-based psychological services delivered in a variety of web-based formats (eg, self-help and therapist-assisted interventions). Robust and rigorous studies of adaptive web-based intervention designs are scarce. No identified randomized clinical trial has investigated the efficacy of a 2-stage adaptive design, whereby the program-only condition or no support dMH treatment program is augmented by either low or high therapist assistance, if a participant does not improve or engage in the program-only condition. The primary objective is to assess whether low or high therapist-assisted support delivered via video chat is more effective in reducing anxiety and depressive symptoms compared with a dMH program-only condition. The secondary objective is to evaluate the role of motivation; self-efficacy; and preferences in participant engagement, adherence, and clinical outcomes (anxiety and depression symptoms) among the 3 treatment conditions (program only, low-intensity therapist assistance, and high-intensity therapist assistance). A mixed methods analysis of factors affecting participant attrition, participant reasons for nonengagement and withdrawal, and therapist training and implementation of dMH interventions will be completed. Qualitative data regarding participant and therapist experiences and satisfaction with video chat assessment and treatment will also be analyzed. Australian adults (N=137) with symptoms or a diagnosis of anxiety or depression will be screened for eligibility and given access to the 8-module Life Flex dMH treatment program. On day 15, participants who meet the augmentation criteria will be stepped up via block randomization to receive therapist assistance delivered via video chat for either 10 minutes (low intensity) or 50 minutes (high intensity) per week. This adaptive trial will implement a mixed methods design, with outcomes assessed before the intervention (week 0), during the intervention (weeks 3 and 6), after the intervention (week 9), and at the 3-month follow-up (week 21). The primary outcome measures are for anxiety (Generalized Anxiety Disorder-7) and depression severity (Patient Health Questionnaire-9). Measures of working alliance, health status, health resources, preferences, self-efficacy, and motivation will be used for secondary outcomes. Qualitative methods will be used to explore participant and therapist experiences of video chat assessment and treatment, participant reasons for withdrawal and nonengagement, and therapist training and implementation experiences. Data collection commenced in November 2020 and was completed at the end of March 2022. This is the first mixed methods adaptive trial to explore the comparative efficacy of different intensity levels of self-help and a therapist-assisted dMH intervention program delivered via video chat for adults with anxiety or depression. Anticipated results may have implications for the implementation of dMH interventions. Australian and New Zealand Clinical Trials Registry 12620000422921; https://tinyurl.com/t9cyu372.

Variation of body weight supported treadmill training parameters during a single session can modulate muscle activity patterns in post-stroke gait

Evidence supporting the benefits of locomotor training (LT) to improve walking ability following stroke are inconclusive and could likely be improved with a better understanding of the effects of individual parameters i.e., body weight support (BWS), speed, and therapist assistance and their interactions with walking ability and specific impairments. We evaluated changes in muscle activity of thirty-seven individuals with chronic stroke (> 6 months), in response to a single session of LT at their self-selected or fastest-comfortable speed (FS) with three levels of BWS (0%, 15%, and 30%), and at FS with 30% BWS and seven different combinations of therapist assistance at the paretic foot, non-paretic foot, and trunk. Altered Muscle Activation Pattern (AMAP), a previously developed tool in our lab was used to evaluate the effects of LT parameter variation on eight lower-extremity muscle patterns in individuals with stroke. Repeated-measures mixed-model ANOVA was used to determine the effects of speed, BWS, and their interaction on AMAP scores. The Wilcoxon-signed rank test was used to determine the effects of therapist-assisted conditions on AMAP scores. Increased BWS mostly improved lower-extremity muscle activity patterns, but increased speed resulted in worse plantar flexor activity. Abnormal early plantar flexor activity during stance decreased with assistance at trunk and both feet, exaggerated plantar flexor activity during late swing decreased with assistance to the non-paretic foot or trunk, and diminished gluteus medius activity during stance increased with assistance to paretic foot and/or trunk. Therefore, different sets of training parameters have different immediate effects on activation patterns of each muscle and gait subphases.

A randomized controlled trial to pilot the efficacy of a computer-based intervention with elements of virtual reality and limited therapist assistance for the treatment of post-traumatic stress disorder.

Although well-established therapies exist for post-traumatic stress disorder (PTSD), barriers to seek mental health care are high. Technology-based interventions may play a role in improving the reach of efforts to treat, especially when therapist availability is low. The goal of the current randomized controlled trial was to pilot the efficacy of a computer-based trauma intervention with elements of virtual reality (VR; 3MR system) and limited therapist involvement for the treatment of PTSD in a childhood sexual abuse (CSA) and war veteran sample and to compare this to "treatment as usual" (TAU). TAU consisted of evidence-based approaches such as imaginal exposure, EMDR, or narrative exposure therapy. A total of 44 patients with PTSD were included and randomly assigned to 12 sessions of 3MR intervention or TAU (completer n 3MR = 12, TAU = 18). Several measures (PCL-5, BDI-II, OQ-45-2, and the M.I.N.I. 5.0.0.) were administered to measure symptoms of PTSD and depression and scores of overall well-being at pre, post, and a three-month follow-up measurement. Analyses suggest that symptoms of PTSD and depression in the 3MR condition decreased, and overall well-being increased between pre and post measurements. Results did not indicate any clear differences between the treatment conditions over time which suggests that treatment gains of the 3MR intervention seem no less than those of TAU. Finally, both treatment conditions produced similar remission rates of PTSD and depression. Therefore, the 3MR intervention could possibly constitute an appropriate treatment alternative. The small sample size as well as evident drop-out rates in the 3MR condition (45%) do warrant further research. The procedures of this study were approved by the Medical Ethical Research Committee (MERC) of the Erasmus Medical Center in Rotterdam (MEC-NL46279.078.13) and pre-registered via ClinicalTrials.gov (Protocol Record CI1-12-S028-1).

Transdiagnostic Internet-Delivered Cognitive Behavioral Therapy for Symptoms of Postpartum Anxiety and Depression: Feasibility Randomized Controlled Trial.

BackgroundPostpartum depression (PPD) and postpartum anxiety (PPA) are often comorbid and are associated with significant personal and economic costs. Fewer than half of the mothers experiencing PPD or PPA symptoms receive face-to-face treatment, suggesting a need for alternative delivery formats such as internet-delivered cognitive behavioral therapy (ICBT).ObjectiveThis pilot study aimed to examine the impact of a therapist-assisted, transdiagnostic ICBT program on symptoms of PPD and PPA, as there is only one previous study on transdiagnostic ICBT with this population, which did not include therapist assistance.MethodsClients endorsing the symptoms of PPD or PPA (N=63) were randomized to an 8-week transdiagnostic ICBT course (Wellbeing Course for New Moms) or to treatment as usual (TAU). Clients completed measures of depression, anxiety, stress, postnatal bonding, and relationship satisfaction, as well as measures of treatment satisfaction and therapeutic alliance, before treatment, after treatment, and at the 1-month follow-up. Outcome measures were also completed at the 6-month follow-up for clients who completed the ICBT course.ResultsBoth the ICBT and TAU groups experienced statistically significant improvements over time. The ICBT group experienced larger improvements after treatment and at the 1-month follow-up on more measures than the TAU group, with medium between-group Cohen d effects on primary outcome measures for anxiety (Cohen d=0.65, 95% CI 0.13-1.17), PPD (Cohen d=0.52, 95% CI 0.01-1.04), and depression (Cohen d=0.56, 95% CI 0.05-1.08), and on secondary outcome measures of overall distress (Cohen d=0.69, 95% CI 0.17-1.21), anxiety (Cohen d=0.59, 95% CI 0.07-1.11), and stress (Cohen d=0.76, 95% CI 0.23-1.28). Time-by-group interactions for proportional reductions between groups over time were only significant after treatment and at the 1-month follow-up for the primary anxiety measure (P=.006). This study was underpowered for detecting small or medium effects. Overall, clients perceived the treatment as credible, and 95% (21/22) of the clients were satisfied with the treatment content and therapist support.ConclusionsFindings from this pilot study provide preliminary support for transdiagnostic ICBT in treating PPD and PPA symptoms to improve access to psychological treatments.Trial RegistrationClinicalTrials.gov NCT04012580; https://clinicaltrials.gov/ct2/show/NCT04012580

Insights into internet-delivered cognitive behavioural therapy for public safety personnel: Exploration of client experiences during and after treatment

Canadian public safety personnel (PSP) experience high rates of mental health problems and barriers to receiving care. Internet-delivered cognitive behavioural therapy (ICBT) may help reduce barriers to care; however, there is no literature involving qualitative analyses of client feedback to describe PSP experiences with ICBT. Identifying these experiences is important because it can inform future use of ICBT with this group that has unique needs. The current study was designed to explore how clients (N = 82) experienced ICBT that had been tailored to meet their needs; specifically, the study assessed their perceptions of program impacts, what clients found helpful, and client suggestions for improvements. The ICBT course included five core lessons, client stories, and nine initial additional resources, as well as flexible frequencies (optional, once weekly, or twice weekly) and durations (8 to 16 weeks) of therapist support. A qualitative reliability thematic analysis was used to analyze client communications and feedback. Responses to a Treatment Satisfaction Questionnaire administered at eight weeks post-enrollment were available for 57 clients. Client emails with therapists were also examined among all clients, including an additional 25 clients who did not complete the Treatment Satisfaction Questionnaire. Themes identified in the qualitative analyses were related to: reported impacts and hindering events, helpful and challenging course skills and content, helpful aspects of the course, and areas for improvement. Clients who completed the Treatment Satisfaction Questionnaire and those who did not reported beneficial impacts from the program, with the most commonly endorsed themes being skill development and normalizing mental health issues. Hindering events were experienced by both groups and included timeline challenges, technology challenges, and negative effects. Comments from both groups suggested that clients had more success than challenges when practicing the skills. Thought challenging was the skill most frequently identified as helpful. Clients described many aspects of the program as helpful with the most frequently endorsed themes being the course format and content, the flexible nature of the course, access to additional materials and case stories, and therapist assistance. Clients also provided suggestions for improving the course (e.g., case stories, additional resources, timelines audio and videos). Overall, client communications suggest that ICBT is accepted and perceived as beneficial among PSP. These results informed rapid improvements to the ICBT program tailored for PSP and may inform others seeking to provide digital mental health services to PSP.

Prevalence of Walking Limitation After Acute Stroke and Its Impact on Discharge to Home.

The purpose of this study was to provide contemporary estimates of the prevalence of lower extremity motor impairment and walking limitation after first-ever stroke and to characterize the predictive nature of early walking ability for being discharged home after acute hospitalization. In this cohort study, data were collected from a metropolitan acute care hospital in Canada at admission for 487 adults with first-ever acute ischemic or hemorrhagic stroke. Lower extremity motor impairment and walking limitation were measured using the National Institutes of Health Stroke Scale and AlphaFIM, respectively. Parallel multivariable logistic regression models were built to predict discharge home after acute hospitalization compared with further hospitalization. For patients surviving a first-ever stroke, 44.1% presented with some degree of lower extremity motor impairment and 46.0% were unable to walk. In a multivariable model built around a binary classification of walking (Nagelkerke R2 = 0.41), those with any ability to walk at admission (with or without therapist assistance) had 9.48 times greater odds of being discharged home (odds ratio = 9.48, 95% CI = 6.11-14.92) than those who were unable. In a parallel multivariable model built around an ordinal classification of walking (Nagelkerke R2 = 0.49), patients had 2.07 times greater odds (odds ratio = 2.07, 95% CI = 1.82-2.38) of being discharged home for each increment on a 6-point walking scale (total dependence to complete independence) assessed at acute admission. Approximately one-half of patients with first-ever stroke present with lower extremity weakness and walking limitation. Early walking ability is a significant predictor of returning home after acute hospitalization, independent of stroke severity. Discharge planning may be facilitated early after stroke with the familiar assessment of walking ability. An early assessment of walking function within days of stroke admission can help to streamline discharge planning. Nearly one-half of all individuals who experience a first-time stroke have walking difficulty when they arrive at the hospital. The severity of the walking limitation can predict whether a patient will eventually be discharged home or go on to further hospitalization.

Tele-Rehabilitation Versus Local Rehabilitation Therapies Assisted by Robotic Devices: A Pilot Study with Patients

The present study aims to evaluate the advantages of a master-slave robotic rehabilitation therapy in which the patient is assisted in real-time by a therapist. We have also explored if this type of strategy is applicable in a tele-rehabilitation environment. A pilot study has been carried out involving 10 patients who have performed a point-to-point rehabilitation exercise supported by three assistance modalities: fixed assistance (without therapist interaction), local therapist assistance, and remote therapist assistance in a simulated tele-rehabiliation scenario. The rehabilitation exercise will be performed using an upper-limb rehabilitation robotic device that assists the patients through force fields. The results suggest that the assistance provided by the therapist is better adapted to patient needs than fixed assistance mode. Therefore, it maximizes the patient’s level of effort, which is an important aspect to improve the rehabilitation outcomes. We have also seen that in a tele-rehabilitation environment it is more difficult to assess when to assist the patient than locally. However, the assistance suits patients better than the fixed assistance mode.

Using Potential Field Function With a Velocity Field Controller to Learn and Reproduce the Therapist's Assistance in Robot-Assisted Rehabilitation

Rehabilitative and assistive practices usually elicit intense and repetitive exercises. Thus, there has been an increasing interest in robotic systems as they are robust and cost-effective in comparison to conventional physical motor-therapy with a therapist. These robots have applications in therapeutic and in-home environments, where there is a necessity for a user-friendly procedure to program the robots for a specific task easily. Our group has suggested robot learning from demonstration (LfD) as an intuitive procedure to program robots via short-term physical interaction in rehabilitation and assistive applications. In this article, a therapist assists a patient, and cooperatively performs a task on a robotic manipulator. Then, using a nonparametric potential field function, the therapist's motion, and interaction force (assistance/resistance) is modeled time-independently via a convex optimization algorithm. Next, in the therapist's absence, the robot provides the patient with the same level of interaction force provided by the therapist along the trajectory. A velocity field controller is also designed to compensate and regulate the patient's deviation from the velocity observed in the demonstration phase. Finally, the efficacy, advantages, and stability of the proposed framework are evaluated in three different experimental scenarios involving spring arrays and an individual with cerebral palsy (CP).

Designing One Degree of Freedom Nursing Robot for Stroke Rehabilitation

Rehabilitation training is a method of post-treatment for physically injured part of body especially the stroke patients. The training task such as massage and repetition exercises are needed to help them to have a normal life as before by a physiotherapist. The physiotherapist or physical therapy is a person who has experienced to treat disease or injury by physical methods. Therefore, a main objective of this paper is to develop a nursing-care robot system that can assist the stroke patient in doing daily activities. A one-degree of freedom nursing robot was designed based on the right-hand bicep using CATIA software. This robot was associated with the electromyography (EMG) sensors in order to collect the data from the muscle contractions. Meanwhile the EMG sensor is a muscle sensor that detect an electrical potential between the two-contraction flexion or extension muscle using the polymer Ag/AgCl coated electrodes. Then, the data from the muscle was sent to the Arduino microcontroller to control the servo motor. The different angle of servo motor can give the direction of movement of the nursing-care robot. The nursing robot was activated by electrical potential from the contraction of the muscle. The value of servo angle from 0 to 100 degrees angle made the robot will move up and down. The movement of robot in up and down direction is likely same as the therapist assistance doing to their patient. The size of robot is about 600 mm × 100 mm length and width and then was fabricated using 3D printer with one degree of freedom (DOF). The limitation of this project is focusing only the hand right hand bicep brachii muscle physiotherapy exercise.

IART: Learning From Demonstration for Assisted Robotic Therapy Using LSTM

In this paper, we present an intelligent Assistant for Robotic Therapy (iART), that provides robotic assistance during 3D trajectory tracking tasks. We propose a novel LSTM-based robot learning from demonstration (LfD) paradigm to mimic a therapist's assistance behavior. iART presents a trajectory agnostic LfD routine that can generalize learned behavior from a single trajectory to any 3D shape. Once the therapist's behavior has been learned, iART enables the patient to modify this behavior as per their preference. The system requires only a single demonstration of 2 minutes and exhibits a mean accuracy of 91.41% in predicting, and hence mimicking a therapist's assistance behavior. The system delivers stable assistance in realtime and successfully reproduces different types of assistance behaviors.

Clinical decision support recommending ventilator settings during noninvasive ventilation.

NIV therapy is used to provide positive pressure ventilation for patients. There are protocols describing what ventilator settings to use to initialize NIV; however, the guidelines for titrating ventilator settings are less specific. We developed an advisory system to recommend NIV ventilator setting titration and recorded respiratory therapist agreement rates at the bedside. We developed an algorithm (NIV advisor) to recommend when to change the non-invasive ventilator settings of IPAP, EPAP, and FiO2 based on patient respiratory parameters. The algorithm utilized a multi-target approach; oxygenation, ventilation, and patient effort. The NIV advisor recommended ventilator settings to move the patient's respiratory parameters in a preferred target range. We implemented a pilot study evaluating the usability of the NIV advisor on 10 patients receiving critical care with non-invasive ventilation (NIV). Respiratory therapists were asked their agreement on recommendations from the NIV advisor at the patient's bedside. Bedside respiratory therapists agreed with 91% of the ventilator setting recommendations from the NIV advisor. The POB and VT values were the respiratory parameters that were most often out of the preferred target range. The IPAP ventilator setting was the setting most often considered in need of changing by the NIV advisor. The respiratory therapists agreed with the majority of the recommendations from the NIV advisor. We consider the IPAP recommendations informative in providing the respiratory therapist assistance in targeting preferred POB and Vt values, as these values were frequently out of the target ranges. This pilot implementation was unable to produce the results required to determine the value of the EPAP recommendations. The FiO2 recommendations from the NIV advisor were treated as ancillary information behind the IPAP recommendations.

Development of the Therapeutic Alliance and its Association With Internet-Based Mindfulness-Based Cognitive Therapy for Distressed Cancer Patients: Secondary Analysis of a Multicenter Randomized Controlled Trial.

BackgroundMindfulness-based cognitive therapy (MBCT) is an evidence-based group-based psychological treatment in oncology, resulting in reduction of depressive and anxiety symptoms. Internet-based MBCT (eMBCT) has been found to be an effective alternative for MBCT. The therapeutic alliance (the bond between therapist and patient,) is known to have a significant impact on psychological treatment outcomes, including MBCT. A primary concern in the practice of eMBCT is whether a good therapeutic alliance can develop. Although evidence for the beneficial effect of therapist assistance on treatment outcome in internet-based interventions (IBIs) is accumulating, it is still unclear whether the therapeutic alliance is related to outcome in IBIs.ObjectiveThis study aimed to (1) explore whether early therapeutic alliance predicts treatment dropout in MBCT or eMBCT, (2) compare the development of the therapeutic alliance during eMBCT and MBCT, and (3) examine whether early therapeutic alliance is a predictor of the reduction of psychological distress and the increase of mental well-being at posttreatment in both conditions.MethodsThis study was part of a multicenter randomized controlled trial (n=245) on the effectiveness of MBCT or eMBCT for distressed cancer patients. The therapeutic alliance was measured at the start of week 2 (ie, early therapeutic alliance), week 5, and week 9. Outcome measures were psychological distress, measured with the Hospital Anxiety and Depression Scale, and mental well-being, measured with the Mental Health Continuum-Short Form.ResultsThe strength of early therapeutic alliance did not predict treatment dropout in MBCT or eMBCT (B=−.39; P=.21). Therapeutic alliance increased over time in both conditions (F2,90=16.46; Wilks λ=0.732; P<.001). This increase did not differ between eMBCT and MBCT (F1,91=0.114; P=.74). Therapeutic alliance at week 2 predicted a decrease in psychological distress (B=−.12; t 114=−2.656; P=.01) and an increase in mental well-being (B=.23; t 113=2.651; P=.01) at posttreatment. The relationship with reduction of psychological distress differed between treatments: a weaker early therapeutic alliance predicted higher psychological distress at posttreatment in MBCT but not in eMBCT (B=.22; t 113=2.261; P=.03).ConclusionsA therapeutic alliance can develop in both eMBCT and MBCT. Findings revealed that the strength of early alliance did not predict treatment dropout. Furthermore, the level of therapeutic alliance predicted reduced psychological distress and increased mental well-being at posttreatment in both conditions. Interestingly, the strength of therapeutic alliance appeared to be more related to treatment outcome in group-based MBCT than in eMBCT.Trial RegistrationClinicalTrials.gov NCT02138513; https://clinicaltrials.gov/ct2/show/NCT02138513

Development of the Internet-Delivered Cognitive Behaviour Therapy Undesirable Therapist Behaviours Scale (ICBT-UTBS)

Internet-delivered cognitive behaviour therapy (ICBT) is often provided with therapist assistance via asynchronous secure emails, but there is limited research on undesirable behaviours exhibited by therapists in their correspondence with patients. In this study, an ICBT-Undesirable Therapist Behaviour Scale (ICBT-UTBS) was developed and used to assess the nature, frequency, and correlates of undesirable therapist behaviours in routine practice. Thematic analysis was used to identify undesirable therapist behaviours in 720 emails sent to 91 randomly selected patients in the context of a previous clinical trial of transdiagnostic ICBT for depression and anxiety. The following undesirable behaviours were identified, albeit infrequently, in therapist emails: inadequate detail (6.4%), unaddressed content (4.0%), unsupportive tone (0.6%), missed correspondence (0.6%), inappropriate self-disclosure (0.6%), and unmanaged risk (0.3%). At least one undesirable behaviour was found in 10.7% of all emails coded. Moreover, 37.4% of patients received at least one email containing an undesirable therapist behaviour. Number of undesirable therapist behaviours was not correlated with patient engagement, working alliance, treatment satisfaction, or patient outcome variables. However, undesirable therapist behaviours were negatively correlated with patient gender and therapist characteristics (e.g., clinical setting, therapist profession). The results of the present study provide preliminary psychometric support for the ICBT-UTBS, a measure of ICBT treatment integrity. In the future, the ICBT-UTBS should be used in combination with the ICBT-Therapist Rating Scale (ICBT-TRS), a measure of desirable or recommended therapist behaviours, for training purposes and to monitor ICBT therapists in routine practice.

Predicting Mobility Limitations in Patients With Total Knee Arthroplasty in the Inpatient Setting

ObjectiveTo develop a prediction model for postoperative day 3 mobility limitations in patients undergoing total knee arthroplasty (TKA). DesignProspective cohort study. SettingInpatients in a tertiary care hospital. ParticipantsA sample of patients (N=2300) who underwent primary TKA in 2016-2017. InterventionsNot applicable. Main Outcome MeasureCandidate predictors included demographic variables and preoperative clinical and psychosocial measures. The outcome of interest was mobility limitations on post-TKA day 3, and this was determined a priori by an ordinal mobility outcome hierarchy based on the type of the gait aids prescribed and the level of physiotherapist assistance provided. To develop the model, we fitted a multivariable proportional odds regression model with bootstrap internal validation. We used a model approximation approach to create a simplified model that approximated predictions from the full model with 95% accuracy. ResultsOn post-TKA day 3, 11% of patients required both walkers and therapist assistance to ambulate safely. Our prediction model had a concordance index of 0.72 (95% confidence interval, 0.68-0.75) when evaluating these patients. In the simplified model, predictors of greater mobility limitations included older age, greater walking aid support required preoperatively, less preoperative knee flexion range of movement, low-volume surgeon, contralateral knee pain, higher body mass index, non-Chinese race, and greater self-reported walking limitations preoperatively. ConclusionWe have developed a prediction model to identify patients who are at risk for mobility limitations in the inpatient setting. When used preoperatively as part of a shared-decision making process, it can potentially influence rehabilitation strategies and facilitate discharge planning.

A Therapist-Taught Robotic System for Assistance During Gait Therapy Targeting Foot Drop

The adoption of robots in rehabilitation medicine settings has become increasingly attractive in recent years. Robots are capable of providing repetitive, high-intensity physiotherapy. In this paper, we apply kinesthetic teaching principles to a robotic system in order to allow it to first learn and then imitate a therapist's behavior while assisting a patient in a lower-limb therapy task. A therapist's assistance in lifting a patient during treadmill-based gait therapy is statistically encoded by the system using Learning-from-Demonstration (LfD) techniques. Later, the therapist's assistance is imitated by the robot, allowing the patient to continue practicing in the absence of the therapist. Preliminary experiments are performed with inexperienced users playing the role of the assisting therapist, and with healthy participants (wearing an elastic cord to simulate foot drop) playing the role of a patient. Toe clearance values are recorded, which show that the system is able to provide the full clearance needed by the patient to practice in the absence of the therapist.
