Abstract
OBJECTIVE To determine the feasibility and acceptability of a diabetes insulin self-management education (DIME) group intervention for people with type 2 diabetes starting insulin. DESIGN Single-centre parallel randomised pilot trial. SETTING Primary care, South London, UK. SUBJECTS Adults with type 2 diabetes, requiring insulin treatment, on maximum tolerated dose of 2 or more oral antidiabetic drugs with HbA1c > / = 7.5% (58 mmol/mol) on 2 occasions. We excluded people who were non-fluent in English; morbid obesity (BMI > / = 35 kg/m2); in employment that contraindicates insulin treatment; and those with severe depression, anxiety disorders, psychotic disorders, personality disorders, or cognitive impairment. METHODS Participants were randomised using blocks of 2 or 4 to 3, 2-h group, face-to-face, DIME sessions or standard insulin group education sessions (control). We assessed feasibility according to consent to randomisation and attendance at intervention (DIME) and standard group insulin education sessions. Acceptability of the interventions was determined using exit interviews. We additionally measured change in self-reported insulin beliefs, diabetes distress and depressive symptoms between baseline and 6-month post-randomisation. RESULTS There were 28 potentially eligible participants, of which 17 consented to randomisation, 9 were allocated to the DIME group intervention and 8 were allocated to the standard group insulin education. Three people withdrew from the study (1 from DIME and 2 from standard insulin education) before the start of the first session and did not complete baseline questionnaires. Of the remaining participants (n = 14), all DIME participants (n = 8) completed all 3 sessions, and all standard insulin education participants (n = 6) completed at least 1 standard insulin education session. The median group size was 2, the mean age of participants was 57.57 (SD 6.45) years, and 64% were female (n = 9). Exit interviews demonstrated that all participants (n = 7) found the group sessions acceptable, and thematic analysis of interview transcripts indicated social support, the content of group sessions and post-group experiences were positive, especially amongst DIME participants. There was improvement on self-report questionnaires. CONCLUSIONS The DIME intervention was acceptable and feasible to deliver to participants with type 2 diabetes starting insulin in South London, UK. TRIAL REGISTRATION International Study Registration Clinical Trial Network (ISRCTN registration number 13339678).

'Is insulin right for me?': Feasibility of a pilot randomised controlled trial and acceptability of a web-based intervention to reduce psychological barriers to insulin therapy among adults with type 2 diabetes. Diabet Med 2022; 39:e14759. [PMID: 34865232 DOI: 10.1111/dme.14759] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Accepted: 12/03/2021] [Indexed: 11/28/2022]
Abstract
AIMS Acceptable and accessible interventions are needed to address 'psychological insulin resistance', which is a common barrier to insulin uptake among adults with type 2 diabetes (T2D). Our aim was to test the feasibility of a randomised controlled trial (RCT) study design and acceptability of a theoretically grounded, psycho-educational, web-based resource to reduce negative insulin appraisals among adults with T2D. METHODS A double-blinded, parallel group, two-arm pilot RCT (1:1), comparing intervention with active control (existing online information about insulin). Eligible participants were Australian adults with T2D, taking oral diabetes medications. EXCLUSION CRITERIA prior use of injectable medicines; being 'very willing' to commence insulin. Primary outcomes: study feasibility (recruitment ease, protocol fulfilment, attrition, data completeness); secondary outcomes: intervention acceptability (intervention engagement, user feedback) and likely efficacy (negative Insulin Treatment Appraisal Scale [ITAS] scores at follow-up). Online surveys completed at baseline and 2 weeks. RESULTS During 4-week recruitment, 76 people expressed interest: 51 eligible and 35 enrolled (intervention = 17, control = 18; median[interquartile range] age = 62[53, 69] years; 17 women). Protocol fulfilment achieved by 26 (74%) participants (n = 13 per arm), with low participant attrition (n = 6, 17%). Intervention acceptability was high (>80% endorsement, except format preference = 60%). ITAS negative scores differed between-groups at follow-up (M diff = -6.5, 95% confidence interval: -10.7 to -2.4), favouring the intervention. CONCLUSIONS This novel web-based resource ("Is insulin right for me?") is acceptable and associated with a likely reduction in negative insulin appraisals, relative to existing resources. This pilot shows the study design is feasible and supports conduct of a fully powered RCT.

Abstract
INTRODUCTION Psychological barriers to insulin therapy are associated with the delay of clinically indicated treatment intensification for people with type 2 diabetes (T2D), yet few evidence-based interventions exist to address these barriers. We describe the protocol for a randomised controlled trial (RCT) examining the efficacy of a novel, theoretically grounded, psychoeducational, web-based resource designed to reduce psychological barriers to insulin among adults with non-insulin treated T2D: 'Is insulin right for me?'. METHODS AND ANALYSIS Double-blind, parallel group RCT. A target sample of N=392 participants (n=196/arm) will be randomised (1:1) to 'Is insulin right for me?' (intervention) or widely available online resources (control). Eligible participants include adults (18-75 years), residing in Australia, currently taking oral hypoglycaemic agents to manage T2D. They will be primarily recruited via invitations and reminders from the national diabetes registry (from a purposefully selected sample of N≥12 000). EXCLUSION CRITERIA experience of self-administered injectable; previously enrolled in pilot RCT; 'very willing' to start insulin as baseline. Outcomes will be assessed via online survey at 2 weeks and 6 months. Primary outcome between-group: difference in mean negative Insulin Treatment Appraisal Scores (ITAS negative) at 2-week and 6-month follow-up. SECONDARY OUTCOMES between-group differences in mean positive insulin appraisals (ITAS positive) and percentage difference in intention to commence insulin at follow-up time points. All data analyses will be conducted according to the intention-to-treat principle. ETHICS AND DISSEMINATION Deakin University Human Research Ethics Committee (2020-073). Dissemination via peer-reviewed journals, conferences and a plain-language summary. TRIAL REGISTRATION NUMBER ACTRN12621000191897; Australian and New Zealand Clinical Trials Registry.

Abstract
OBJECTIVE To develop a theory and evidence-based web intervention to reduce psychological barriers towards insulin therapy among adults with non-insulin-treated type 2 diabetes (T2D). METHODS Salient psychological barriers towards insulin were identified from the literature and classified using the Theoretical Domains Framework (TDF). Relevant TDF domains were mapped to evidence-based behaviour change techniques (BCTs), which informed the content for each barrier. Acceptability was explored using cognitive debriefing interviews (n=6 adults with T2D). RESULTS 'Is Insulin Right for Me' addresses eight barriers, phrased as common questions: Does insulin mean my diabetes is more serious? Do insulin injections cause complications? Is it my fault I need to inject insulin? Will I gain weight? Will injecting hurt? What about hypos? Will injecting insulin be a burden? What will others think of me? BCTs, including persuasive communication and modelling/demonstration, were delivered using appropriate methods (eg, demonstration of the injection process). Participant suggestions for improvement included clear and direct messages, normalising insulin and avoiding confronting images. CONCLUSIONS 'Is Insulin Right for Me' is the first theory and evidence-based, web intervention designed to reduce psychological barriers towards insulin therapy for adults with T2D. Evaluation is needed to determine its impact on negative appraisals and receptiveness towards insulin.

Abstract
The aim of this narrative review was to determine the contribution of behavioural and psychosocial research to the field of medication-taking for adults with type 2 diabetes over the past 25 years. We review the behavioural and psychosocial literature relevant to adults with type 2 diabetes who are treated with oral antidiabetes agents, glucagon-like peptide-1 receptor agonists and insulin. Delayed uptake of, omission of and non-persistence with medications are significant problems among adults with type 2 diabetes. At each stage of the course of diabetes, during which medication to lower blood glucose is initiated or intensified, ~50% of people take less medication than prescribed. Research aimed at increasing optimal medication-taking behaviour has targeted 'forgetfulness', developing interventions which aid medication-taking, such as reminder devices, with limited success. In parallel, investigation of beliefs about medication has provided insights into the perceived necessity of and concerns about medication and how these inform medication-taking decisions. Guidance is available for health professionals to facilitate shared decision-making, particularly with insulin therapy; however, interventions addressing medication beliefs are limited. Optimal medication-taking behaviour is essential to prevent hyperglycaemia in adults with type 2 diabetes. Evidence from the past 25 years has demonstrated the association between medication beliefs and medication-taking behaviour. Health professionals need to address medication concerns, and establish and demonstrate the utility of diabetes medication with the individual within the clinical consultation. There are interventions that may assist diabetes health professionals in the shared decision-making process, but further development and more robust evaluation of these tools and techniques is required.

Abstract
INTRODUCTION Psychological insulin resistance (PIR) is common among type II diabetes (DM) patients. Although interventions to reduce PIR have been suggested, there is no standardized intervention to reduce PIR. This trial aimed to assess the preliminary effectiveness of a well-structured interventional patient group (for sample size calculation for larger trials), as well as the acceptability and feasibility of this intervention group. METHODS This study used a quasi-experimental, mixed-method approach. Fifty-three patients with DM were recruited to an interventional group that included a general education of DM and insulin, an insulin pen demonstration, and an insulin-using peer sharing session. Each group consisted of around 15 participants and lasted for 2 h each. The validated Chinese version of the insulin treatment appraisal scale (C-ITAS) was administered before, immediately after, and 1 month after the intervention to measure any changes in the participants' PIR. Patients were interviewed to assess the acceptability of the intervention until data saturation. RESULTS Repeated measures ANOVA showed that the post-intervention C-ITAS scores (immediately post group and at 1 month) were lower than the pre-intervention C-ITAS scores (p < 0.001). Changes in multiple attitudes toward insulin were detected before and after the group intervention. Ten patient interviews were conducted and found that the intervention was welcomed by all interviewees; no discomfort or adverse reactions were reported. CONCLUSION Preliminary results showed that patient intervention groups with general education, insulin pen demonstration, and peer sharing appeared to be safe, acceptable, and effective in reducing PIR. Larger multicenter trials are needed to generalize these findings.

Abstract
PURPOSE OF REVIEW This study aims to examine the operationalisation of 'psychological insulin resistance' (PIR) among people with type 2 diabetes and to identify and critique relevant measures. RECENT FINDINGS PIR has been operationalised as (1) the assessment of attitudes or beliefs about insulin therapy and (2) hypothetical or actual resistance, or unwillingness, to use to insulin. Five validated PIR questionnaires were identified. None was fully comprehensive of all aspects of PIR, and the rigour and reporting of questionnaire development and psychometric validation varied considerably between measures. Assessment of PIR should focus on the identification of negative and positive attitudes towards insulin use. Actual or hypothetical insulin refusal may be better conceptualised as a potential consequence of PIR, as its assessment overlooks the attitudes that may prevent insulin use. This paper provides guidance on the selection of questionnaires for clinical or research purpose and the development of new, or improvement of existing, questionnaires.
