Attention control group activities and perceived benefit in a trial of a behavioral intervention for older adults

Design and Methods of the Early Age-Related Hearing Loss Investigation Randomized Controlled Trial

OBJECTIVE

Hearing loss has been identified as a major modifiable risk factor for cognitive decline. The Early Age-Related Hearing Loss Investigation (EARHLI) study will assess the mechanisms linking early age-related hearing loss (ARHL) and cognitive impairment.

STUDY DESIGN

Randomized, controlled, single-site, early phase II, superiority trial.

SETTING

Tertiary academic medical center.

PARTICIPANTS

One hundred fifty participants aged 55 to 75 years with early ARHL (severity defined as borderline to moderate) and amnestic mild cognitive impairment will be included.

INTERVENTIONS

Participants will be randomized 1:1 to a best practice hearing intervention or a health education control.

MAIN OUTCOME MEASURES

The primary study outcome is cognition measured by the Alzheimer Disease Cooperative Study-Preclinical Alzheimer Cognitive Composite. Secondary outcomes include additional measures of cognition, social engagement, and brain organization/connectivity.

RESULTS

Trial enrollment will begin in early 2024.

CONCLUSIONS

After its completion in 2028, the EARHLI trial should offer evidence on the effect of hearing treatment versus a health education control on cognitive performance, social engagement, and brain organization/connectivity in 55- to 75-year-old community-dwelling adults with early ARHL and amnestic mild cognitive impairment.

Ensuring Intervention Fidelity of an Attention Control Arm in a Multisite Randomized Controlled Trial

BACKGROUND

Intervention fidelity is a critical element of randomized controlled trials, yet reporting of intervention fidelity among attention control arms is limited. Lack of fidelity to attention control procedures can affect study outcomes by either overestimating or underestimating the efficacy of the intervention under examination.

OBJECTIVES

This brief report describes the approach researchers took to promote fidelity to the attention control arm of a pediatric palliative care randomized controlled trial funded by the National Institutes of Health.

METHODS

The Informational Meetings for Planning and Coordinating Treatment trial aims to determine the efficacy of a communication intervention that uses care team dyads (i.e., physicians partnered with nurses or advanced practice providers) to engage parents of children with cancer who have a poor prognosis in structured conversations about prognostic information, goals of care, and care planning. The intervention is compared with an attention control arm, which provides parents with structured conversations on common pediatric cancer education topics, such as talking to their child about their cancer, clinical trials, cancer treatment, side effects, and so forth. National Institutes of Health guidelines for assessing and implementing strategies to promote intervention fidelity were used to design (a) the attention control arm of a randomized controlled trial, (b) related attention control arm training, and (c) quality assurance monitoring.

RESULTS

Attention control study procedures were designed to mirror that of the intervention arm (i.e., same number, frequency, and time spent in study visits). Cluster randomization was used to allocate care team dyads to one arm of the randomized controlled trial. Care team dyads assigned to the attention control arm participated in online training sessions to learn attention control procedures, the different roles of research team members, and quality assurance methods. Fidelity to attention control procedures is assessed by both the interveners themselves and a quality assurance team.

DISCUSSION

Study design, training, and delivery are all critical to attention control fidelity. Baseline training often needs to be supplemented with booster training when time gaps occur between study start-up and implementation. Quality assurance procedures are essential to determine whether interveners consistently deliver attention control procedures correctly.

One-year cognitive outcomes from a multiple real-world skill learning intervention with older adults

OBJECTIVES

Novel skill learning has been shown to have cognitive benefits in the short-term (up to a few months). Two studies expanded on prior research by investigating whether learning multiple novel real-world skills simultaneously (e.g. Spanish, drawing, music composition), for a minimum of six hours a week, would yield 1-year cognitive gains.

METHOD

Following a 3-month multi-skill learning intervention, Study 1 (N = 6, Mage = 66 years, SDage = 6.41) and Study 2 (N = 27, Mage = 69 years, SDage = 7.12) participants completed follow-up cognitive assessments 3 months, 6 months, and one year after the intervention period. Cognitive assessments tested executive function (working memory and cognitive control) and verbal episodic memory.

RESULTS

Linear mixed-effects models revealed improvements in multiple cognitive outcomes from before the intervention to the follow-up timepoints. Specifically, executive function increased from pre-test to the 1-year follow-up for both studies (an effect driven mostly by cognitive control scores).

DISCUSSION

Our findings provide evidence that simultaneously learning real-world skills can lead to long-term improvements in cognition during older adulthood. Future work with diverse samples could investigate individual differences in gains. Overall, our findings promote the benefits of lifelong learning, namely, to improve cognitive abilities in older adulthood.

A randomised controlled trial of a nutrition and a decision support intervention to enable partnerships with families of critically ill patients

AIMS AND OBJECTIVES

The aim of the study was to investigate the effect of supporting family members to partner with health professionals on nutrition intakes and decision-making and to evaluate intervention and study feasibility.

BACKGROUND

Family partnerships can improve outcomes for critically ill patients and family members. Interventions that support families to engage with health professionals require evaluation.

DESIGN

A multi-centre, randomised, parallel group superiority Phase II randomised controlled trial.

METHODS

In nine intensive care units (ICUs) across three countries, critically ill patients ≥60 years, or those 55-59 years with advanced chronic diseases and expected ICU length of stay >72 h and their family member were enrolled between 9 May 2017 and 31 March 2020. Participants were randomised (1:1:1) to either a decision support or nutrition optimisation family-centred intervention, or usual care. Primary outcomes included protein and energy intake during ICU and hospital stay (nutrition intervention) and family satisfaction (decision support). Study feasibility was assessed as a composite of consent rate, intervention adherence, contamination and physician awareness of intervention assignment.

RESULTS

We randomised 135 patients/family members (consent rate 51.7%). The average rate of randomisation was 0.5 (0.13-1.53) per month. Unavailability (staff/family) was the major contributor to families not being approached for consent. Declined consent was attributed to families feeling overwhelmed (58/126, 46%). Pandemic visitor restrictions contributed to early study cessation. Intervention adherence for the decision support intervention was 76.9%-100.0% and for the nutrition intervention was 44.8%-100.0%. Nutritional adequacy, decisional conflict, satisfaction with decision-making and overall family satisfaction with ICU were similar for all groups.

CONCLUSIONS

Active partnerships between family members and health professionals are important but can be challenging to achieve in critical care contexts. We were unable to demonstrate the efficacy of either intervention. Feasibility outcomes suggest further refinement of interventions and study protocol may be warranted.

RELEVANCE TO CLINICAL PRACTICE

Interventions to promote family partnerships in critical illness are needed but require a greater understanding of the extent to which families want and are able to engage and the activities in which they have most impact.

REPORTING METHOD

This study has been reported following the Consolidated Standards of Reporting Trials (CONSORT) and the Template for Intervention Description and Replication (TIDieR) guidelines.

PATIENT OR PUBLIC CONTRIBUTION

Patients and caregivers were engaged in and contributed to the development and subsequent iterations of the two family-centred interventions use in this study.

Variations in the Design and Use of Attention Control Groups in Type 2 Diabetes Randomized Controlled Trials: a Systematic Review

PURPOSE OF REVIEW

In type 2 diabetes (T2D) research, the phrase "attention control group" (ACGs) has been used with varying descriptions. We aimed to systematically review the variations in the design and use of ACGs for T2D studies.

RECENT FINDINGS

Twenty studies utilizing ACGs were included in the final evaluation. Control group activities had the potential to influence the primary outcome of the study in 13 of the 20 articles. Prevention of contamination across groups was not mentioned in 45% of the articles. Eighty-five percent of articles met or somewhat met the criteria for having comparable activities between the ACG and intervention arms. Wide variations in descriptions and the lack of standardization have led to an inaccurate use of the phrase "ACGs" when describing the control arm of trials, indicating a need for future research with focus on the adoption of uniform guidelines for use of ACGs in T2D RCTs.

An Evaluation of a Pesticide Training Program to Reduce Pesticide Exposure and Enhance Safety among Female Farmworkers in Nan, Thailand

BACKGROUND

Although exposure to chemical pesticides is known to cause negative effects on human health, farmers in Ban Luang, Nan, Thailand, continue to use them regularly to protect crops. This study focused on mothers who were engaged in farm tasks and had children between the ages of 0 to 72 months, with the objective of reducing pesticide exposure.

METHODS

This study was conducted from May 2020 to October 2020 in the Ban Fa and Ban Phi sub-districts in Ban Luang due to the high use of pesticides in these areas. A systematic random sampling technique was used to recruit 78 mothers exposed to pesticides. Thirty-nine mothers from Ban Fa district were randomly assigned to the intervention group and 39 from Ban Phi to the control group over a 3-month period. This study applied a pesticide behavioral change training program for the intervention group. To assess the effectiveness of the program, the study compared the results of a questionnaire regarding knowledge, attitude, and practice (KAP) and health beliefs related to pesticide exposure as well as the levels of acetylcholinesterase (AChE) and butyryl cholinesterase (BChE) enzymes, biomarkers of exposure to pesticides, before and after the intervention using ANCOVA statistical test. Furthermore, to evaluate the effectiveness of the intervention program, a paired t-test was used to investigate the in-home pesticide safety assessment.

RESULTS

After the intervention, we observed no significant change in AChE; however, a significant improvement in BChE (p < 0.05), a marker of short-term recovery, was observed. Pesticides can cause a reduction in AChE and BChE, however, after eliminating pesticides, BChE takes a shorter time (about 30-50 days) to recover than AChE (around 90-120 days). Therefore, increases in the measured concentrations of AChE and/or BChE suggest the presence of less chemicals from pesticides in the human body. The study also found a significant improvement in KAP and beliefs about chemical pesticide exposure after the intervention (p < 0.05). Furthermore, using a paired t-test, we found a significant increase in pesticide safety practices (p < 0.05) in the intervention group and a borderline significant increase regarding in-home safety (p = 0.051) in the control group.

CONCLUSIONS

Based on the results, the constructs of the intervention program were effective and could be applied in other agricultural areas in less developed countries. However, due to time limitations during the COVID-19 pandemic, further studies should be conducted to enable data collection over a longer time, with a larger number of subjects providing the ChE levels for the non-agricultural season.

"What I wanted to do was build myself back up and prepare": qualitative findings from the PERCEPT trial of prehabilitation during autologous stem cell transplantation in myeloma

BACKGROUND

The addition of qualitative methodology to randomised controlled trials evaluating complex interventions allows better understanding of contextualised factors and their potential influence on trial delivery and outcomes, as well as opportunities for feedback on trial participation to improve future trial protocols. This study explored the experiences of participation in cancer rehabilitation research during active cancer treatment. Participants were people living with haematological cancer myeloma, undergoing autologous stem cell transplantation (ASCT) recruited to the PERCEPT myeloma pilot trial.

METHODS

A qualitative semi-structured interview study, embedded within a pilot randomised controlled trial of a physiotherapist-led exercise intervention delivered before, during and after ASCT among people living with myeloma. Transcripts were analysed using reflexive thematic analysis.

RESULTS

Interviews from 16 trial participants (n = 8 intervention group; n = 8 control group; mean age 61 years, 56% male) were analysed. Four main themes were identified: (1) "It's not just beneficial for me, it's for people after me as well"; (2) Disparities in experience of recovery - expectations, feeling prepared and support; (3) "What I wanted to do was build myself back up and prepare"; (4) Active ingredients - participants' experience of the trial intervention. Participants reported both altruistic and perceived personal gain as motivators for enrolling in the trial. Disappointment caused by allocation to control arm may have led to participants seeking exercise elsewhere, indicating possible contamination of control condition. Disparities in experience of recovery from transplant were evident with intervention participants reporting greater trajectory of recovery.

CONCLUSIONS

The findings from this embedded qualitative study highlight numerous considerations required when designing pilot and efficacy trials of complex interventions. The addition of qualitative investigation offers greater understanding of motivations for participation, intervention mechanisms at play as well as effects of participation that may impact interpretation of quantitative outcomes.

The long-term effects of primary school-based obesity prevention interventions in children: A systematic review and meta-analysis

INTRODUCTION

This systematic review and meta-analysis investigate the long-term effects of primary school-based obesity prevention interventions on body-mass index (and z-scores), waist circumference (and z-scores) and weight status.

METHODS

Four databases were searched for studies from date of inception until June 8th, 2021. We included randomized controlled trials (RCT) and non-RCTs investigating effects ≥12 months post-intervention of primary school-based interventions with intervention duration ≥6 months and containing a diet and/or physical activity component on outcomes of interest. Articles were assessed on risk of bias and methodological quality by RoB2 and ROBINS-I. Meta-analysis was performed and results were narratively summarized. Evidence quality was assessed with GRADE.

RESULTS

Nineteen studies were included, 9 were pooled in a meta-analysis. No long-term effects were found on body-mass index (+0.06 kg/m² ; CI95% = -0.38, 0.50; I²  = 66%), body-mass index z-scores (-0.08; CI95% = -0.20, 0.04; I²  = 36%), and waist circumference (+0.57 cm; CI95% = -0.62, 1.75; I²  = 13%). Non-pooled studies reported mixed findings regarding long-term effects on body-mass index, body-mass index z-scores and weight status, and no effects on waist circumference and waist circumference z-scores. Evidence certainty was moderate to very low.

DISCUSSION

No clear evidence regarding long-term effects of primary school-based interventions on obesity-related outcomes was found. Recommendations for further research and policy are discussed. Prospero registration ID: CRD42021240446.

Assessing the Suitability of a Virtual 'Pink Warrior' for Older Breast Cancer Survivors during COVID-19: A Pilot Study

The COVID-19 pandemic impacted the conduct of in-person physical activity (PA) interventions among older survivors of BC, who need such interventions to stay active and prevent functional decline. We tested the feasibility of virtually delivering an exergame-based PA intervention to older BC survivors. We enrolled 20 female BC survivors ≥55 years and randomly assigned them to two groups. The intervention group (Pink Warrior 2) received 12 weekly virtual exergame sessions with behavioral coaching, survivorship navigation support, and a Fitbit for self-monitoring. The control group received 12 weekly phone-based survivorship discussion sessions and wore a Mi Band 3. Feasibility was evaluated by rates of recruitment (≥0.92 participants/center/month), retention (≥80%), and group attendance (≥10 sessions), percentage of completed virtual assessments, and number of technology-related issues and adverse events. Intervention acceptability was measured by participants' ratings on a scale of 1 (strongly disagree) to 5 (strongly agree). The recruitment rate was 1.93. The retention and attendance rates were 90% and 88% (≥10 sessions), respectively. Ninety-six percent completed virtual assessments without an adverse event. Acceptability was high (≥4). The intervention met benchmarks for feasibility. Additional research is needed to further understand the impact of virtually delivered PA interventions on older BC survivors.

A narrative sequencing and mentalizing training for adults with autism: A pilot study

Adults diagnosed with autism experience difficulties with understanding the mental states of others, or themselves (mentalizing) and with adequately sequencing personal stories (narrative coherence). Given that the posterior cerebellum is implicated in both skills, as well as in the etiology of autism, we developed a narrative sequencing and mentalizing training for autistic adults. Participants with an official autism diagnosis were randomly assigned to a Training group (n = 17) or a waiting-list Control group (n = 15). The Training group took part in six weekly sessions in groups of three participants lasting each about 60 min. During training, participants had to (re)tell stories from the perspective of the original storyteller and answer questions that required mentalizing. We found significant improvements in mentalizing about others’ beliefs and in narrative coherence for the Training group compared to the Control group immediately after the training compared to before the training. Almost all participants from the Training group expressed beneficial effects of the training on their mood and half of the participants reported positive effects on their self-confidence in social situations. All participants recommended the current training to others. Results are discussed in light of cerebellar theories on sequencing of social actions during mentalizing. Further improvements to the program are suggested. Our results highlight the potential clinical utility of adopting a neuroscience-informed approach to developing novel therapeutic interventions for autistic populations.

Point‐of‐care tools to support optometric care provision to people with age‐related macular degeneration: A randomised, placebo‐controlled trial

Purpose

Age‐related macular degeneration (AMD) is a leading cause of vision impairment. This randomised placebo‐controlled trial investigated whether point‐of‐care tools can improve optometrists' AMD knowledge and/or care provision.

Methods

Australian optometrists (n = 31) completed a demographics survey and theoretical AMD case study multiple‐choice questions (MCQs) to assess their confidence in AMD care provision and AMD knowledge. Participants were then randomly assigned to one of three point‐of‐care tools (online ‘Classification of Age‐related macular degeneration and Risk Assessment Tool’ (CARAT), paper CARAT, or ‘placebo’) to use when providing care to their subsequent 5–10 AMD patients. Participants self‐audited the compliance of their AMD care to best practice for these patients, and a similar number of consecutive patients seen prior to enrolment. Post‐intervention, participants retook the AMD knowledge MCQs and confidence survey.

Results

A total of 29 participants completed the study. At the study endpoint, clinical confidence relative to baseline improved with the paper CARAT, relative to placebo, for knowledge of AMD risk factors, asking patients about these factors and referring for medical retinal sub‐specialist care. There were no between‐group differences for the change in AMD knowledge scores. Considering record documentation for patients with any AMD severity, there were no significant between‐group differences for documenting patient risk factors, AMD severity, clinical examination techniques or management. In a sub‐analysis, the change from baseline in compliance for documenting discussions about patient smoking behaviours for early AMD patients was higher with use of the online CARAT relative to placebo (p = 0.04). For patients with intermediate AMD, the change from baseline in documenting the risk of progression to late AMD was greater among practitioners who used the paper CARAT, relative to placebo (p = 0.04).

Conclusions

This study demonstrates that point‐of‐care clinical tools can improve practitioner confidence and aspects of the documentation of AMD clinical care by optometrists as assessed by self‐audit.

The clinical effectiveness of a physiotherapy delivered physical and psychological group intervention for older adults with neurogenic claudication: the BOOST randomised controlled trial

Background

Neurogenic claudication (NC) is a debilitating spinal condition affecting older adults’ mobility and quality of life.

Methods

A randomized controlled trial of 438 participants evaluated the effectiveness of a physical and psychological group intervention (BOOST program) compared to physiotherapy assessment and tailored advice (best practice advice [BPA]) for older adults with NC. Participants were identified from spinal clinics (community and secondary care) and general practice records and randomized 2:1 to the BOOST program or BPA. The primary outcome was the Oswestry Disability Index (ODI) at 12 months. Data were also collected at 6 months. Other outcomes included ODI walking item, 6-minute walk test (6MWT), and falls. The primary analysis was intention-to-treat.

Results

The average age of participants was 74.9 years (standard deviation [SD] 6.0) and 57% (246/435) were female. There was no significant difference in ODI scores between treatment groups at 12 months (adjusted mean difference [MD]: −1.4 [95% confidence intervals (CI) −4.03, 1.17]), but, at 6 months, ODI scores favored the BOOST program (adjusted MD: −3.7 [95% CI −6.27, −1.06]). At 12 months, the BOOST program resulted in greater improvements in walking capacity (6MWT MD: 21.7m [95% CI 5.96, 37.38]) and ODI walking item (MD: −0.2 [95% CI −0.45, −0.01]) and reduced falls risk (odds ratio: 0.6 [95% CI 0.40, 0.98]) compared to BPA. No serious adverse events were related to either treatment.

Conclusions

The BOOST program substantially improved mobility for older adults with NC. Future iterations of the program will consider ways to improve long-term pain-related disability.

The Effect of Internet-Delivered Cognitive Behavioral Therapy Versus Psychoeducation Only on Psychological Distress in Patients With Noncardiac Chest Pain: Randomized Controlled Trial

Background

Patients with recurrent episodes of noncardiac chest pain (NCCP) experience cardiac anxiety as they misinterpret the pain to be cardiac related and avoid physical activity that they think could threaten their lives. Psychological interventions, such as internet-delivered cognitive behavioral therapy (iCBT), targeting anxiety can be a feasible solution by supporting patients to learn how to perceive and handle their chest pain.

Objective

This study aims to evaluate the effects of a nurse-led iCBT program on cardiac anxiety and other patient-reported outcomes in patients with NCCP.

Methods

Patients with at least two health care consultations because of NCCP during the past 6 months, and who were experiencing cardiac anxiety (Cardiac Anxiety Questionnaire score ≥24), were randomized into 5 weeks of iCBT (n=54) or psychoeducation (n=55). Patients were aged 54 (SD 17) years versus 57 (SD 16) years and were mainly women (32/54, 59% vs 35/55, 64%). The iCBT program comprised psychoeducation, mindfulness, and exposure to physical activity, with weekly homework assignments. The primary outcome was cardiac anxiety. The secondary outcomes were fear of bodily sensations, depressive symptoms, health-related quality of life, and chest pain frequency. Intention-to-treat analysis was applied, and the patients were followed up for 3 months. Mixed model analysis was used to determine between-group differences in primary and secondary outcomes.

Results

No significant differences were found between the iCBT and psychoeducation groups regarding cardiac anxiety or any of the secondary outcomes in terms of the interaction effect of time and group over the 3-month follow-up. iCBT demonstrated a small effect size on cardiac anxiety (Cohen d=0.31). In the iCBT group, 36% (16/44) of patients reported a positive reliable change score (≥11 points on the Cardiac Anxiety Questionnaire), and thus an improvement in cardiac anxiety, compared with 27% of (13/48) patients in the psychoeducation group. Within-group analysis showed further significant improvement in cardiac anxiety (P=.04) at the 3-month follow-up compared with the 5-week follow-up in the iCBT group but not in the psychoeducation group.

Conclusions

iCBT was not superior to psychoeducation in decreasing cardiac anxiety in patients with NCCP. However, iCBT tends to have better long-term effects on psychological distress, including cardiac anxiety, health-related quality of life, and NCCP frequency than psychoeducation. The effects need to be followed up to draw more reliable conclusions.

Intensive Daily Symptom and Function Monitoring Is Feasible and Acceptable to Women Undergoing First-Line Chemotherapy for Gynecologic Cancer

BACKGROUND

Women receiving chemotherapy for gynecologic cancer (GC) experience severe symptoms with associated functional changes. Understanding day-to-day symptom and function variation within and across chemotherapy treatment cycles could inform improved symptom management, but such studies are rare and may be infeasible in clinical care.

OBJECTIVE

The aim of this study was to evaluate feasibility and acceptability of daily symptom monitoring combined with objective and self-reported functional assessments every 21 days during active chemotherapy for GC.

METHODS

Thirty women enrolled in a prospective observational study during first-line chemotherapy completed a daily symptom and falls diary during their entire chemotherapy treatment period. Patient-reported outcomes and objective symptom and function testing were assessed before each chemotherapy appointment. Study outcomes included accrual and attrition rates, completion of study assessments, and qualitative perceptions of study participation.

RESULTS

Participants were 92% White, 60% had high school or higher education, 68% were married/partnered, and 62% had stage III or IV cancer at diagnosis. The study had an 83% accrual rate, 6.6% early withdrawal rate, and 17% total attrition rate. Missing assessments for prechemotherapy patient-reported outcomes and objective assessments ranged from 27% to 35% and 35% to 47% respectively, with a general decrease across cycles. Daily diary completion rate was 83% overall. Participants rated study participation positively.

CONCLUSIONS

Intensive daily symptom and function monitoring was feasible and acceptable to GC patients and may provide a sense of symptom controllability.

IMPLICATIONS FOR PRACTICE

Daily symptom and function monitoring in research studies may provide patients with information to support symptom discussions with the clinical team. Future work should develop proactive symptom management interventions using personalized symptom trajectories.

Guided self-determination intervention versus attention control for people with type 2 diabetes in outpatient clinics: a protocol for a randomised clinical trial

INTRODUCTION

In the management of type 2 diabetes, autonomy-supporting interventions may be a prerequisite to achieving more long-term improvement. Preliminary evidence has shown that the guided self-determination (GSD) method might have an effect on haemoglobin A1c and diabetes distress in people with type 1 diabetes. Previous trials were at risk of uncertainty. Thus, the objective is to investigate the benefits and harms of a GSD intervention versus an attention control group intervention in adults with type 2 diabetes.

METHODS AND ANALYSIS

This trial protocol is guided by the The Standard Protocol Items: Recommendations for International Trials Statement. We describe the protocol for a pragmatic randomised, dual-centre, parallel-group, superiority clinical trial testing a GSD intervention versus an attention control for people with type 2 diabetes in outpatient clinics. The participants (n=224) will be recruited from two diverse regions of Denmark. The experimental stepped-care intervention will consist of three to five GSD sessions lasting up to 1 hour with a trained GSD facilitator. The sessions will be conducted face to face, by video conference or over the telephone. The attention controls will receive three to five sessions lasting up to an hour with a communication-trained healthcare professional provided face to-face, by video conference, or over the telephone. Participants will be included if they have type 2 diabetes,>18 years old, are not pregnant. Participants will be assessed before randomisation, at 5-month, and 12-month follow-up, the latter being the primary. The primary outcome is diabetes distress. Secondary outcomes are quality of life, depressive symptoms and non-serious adverse events. Exploratory outcomes are haemoglobin A1c, motivation and serious adverse events. Data will be collected using REDCap and analysed using Stata V.16.

ETHICS AND DISSEMINATION

The trial will be conducted in compliance with the protocol, the Helsinki Declaration in its latest form, International Harmonisation of Good Clinical Practice guidelines and the applicable regulatory requirement(s). The trial has been approved by the Danish Data Protection Agency (P-2020-864). The Ethics Committee of the Capital Region of Denmark reviewed the trial protocol, but exempted the trial protocol from full review (H-20003638). The results of the trial will be presented at the outpatient clinics treating people with type 2 diabetes, at national and international conferences as well as to associations for people with diabetes and their relatives.
