Development of a group-based behaviour change intervention for people with severe obesity informed by the social identity approach to health.

INTRODUCTION: Interventions to support behaviour change in people living with chronic health conditions increasingly use patient groups as the mode of delivery, but these are often designed without consideration of the group processes that can shape intervention outcomes. This article outlines a new approach to designing group-based behaviour change interventions that prioritizes recipients' shared social identity as group members in facilitating the adoption of established behaviour change techniques (BCTs). The approach is illustrated through an example drawn from research focused on people living with severe obesity. METHODS: A prioritization process was undertaken in collaboration with stakeholders, including behaviour change experts, clinicians, and a former patient to develop an evidence-based, group intervention informed by the social identity approach to health. Three phases of development are reported: (1) identification of the health problem; (2) delineation of intervention mechanisms and operationalization of BCTs for group delivery and (3) intervention manualization. The fourth phase, intervention testing and optimization, is reported elsewhere. RESULTS: A group-based behaviour change intervention was developed, consisting of 12 group sessions and 3 one-to-one consultations. The intervention aimed to support the development of shared social identity among recipients, alongside the delivery of evidence-based BCTs, to improve the likelihood of successful intervention and health outcomes among people living with severe obesity. CONCLUSIONS: A manualized intervention, informed by the social identity approach to health, was systematically designed with input from stakeholders. The development approach employed can inform the design of behavioural interventions in other health contexts where group-based delivery is planned.

Shared social identity and perceived social support among stroke groups during the COVID-19 pandemic: Relationship with psychosocial health.

Community-based peer support groups for stroke survivors are common in the United Kingdom and aim to support rehabilitation. This study of 260 stroke survivors across 118 groups nationally used an online survey format, completed on average 3 months into the pandemic. Analysis of both quantitative and open-ended responses provided insights into how stroke group members maintained contact during the COVID-19 pandemic and how the group processes of shared social identity and perceived social support related to psychosocial outcomes (self-esteem, well-being and loneliness). Group members adapted to the pandemic early through telephone calls (61.6% of participants) and internet-based contact (>70% of participants), although also showed a desire for greater contact with their groups. A stronger sense of shared social identity and perceptions of social support from the stroke groups were weakly associated with reductions in loneliness among members, and greater perceived social support was associated with higher self-esteem. However, having poor health and living alone were more strongly associated with more negative psychosocial outcomes. The discussion considers how barriers to contact during pandemics can be managed, including access and use of online communication, limitations imposed by stroke-related disability, and how the experience of feeling supported and social identification can be better nurtured within remote contexts.

A group-based behavioural intervention for weight management (PROGROUP) versus usual care in adults with severe obesity: a feasibility randomised controlled trial protocol.

BACKGROUND: Approximately 15 million people in the UK live with obesity, around 5 million of whom have severe obesity (body mass index (BMI) ≥35kg/m2). Having severe obesity markedly compromises health, well-being and quality of life, and substantially reduces life expectancy. These adverse outcomes are prevented or ameliorated by weight loss, for which sustained behavioural change is the cornerstone of treatment. Although NHS specialist 'Tier 3' Weight Management Services (T3WMS) support people with severe obesity, using individual and group-based treatment, the current evidence on optimal intervention design and outcomes is limited. Due to heterogeneity of severe obesity, there is a need to tailor treatment to address individual needs. Despite this heterogeneity, there are good reasons to suspect that a structured group-based behavioural intervention may be more effective and cost-effective for the treatment of severe obesity compared to usual care. The aims of this study are to test the feasibility of establishing and delivering a multi-centre randomised controlled clinical trial to compare a group-based behavioural intervention versus usual care in people with severe obesity. METHODS: This feasibility randomised controlled study is a partially clustered multi-centre trial of PROGROUP (a novel group-based behavioural intervention) versus usual care. Adults ≥18 years of age who have been newly referred to and accepted by NHS T3WMS will be eligible if they have a BMI ≥40, or ≥35 kg/m2 with comorbidity, are suitable for group-based care and are willing to be randomised. Exclusion criteria are participation in another weight management study, planned bariatric surgery during the trial, and unwillingness or inability to attend group sessions. Outcome assessors will be blinded to treatment allocation and success of blinding will be evaluated. Clinical measures will be collected at baseline, 6 and 12 months post-randomisation. Secondary outcome measures will be self-reported and collected remotely. Process and economic evaluations will be conducted. DISCUSSION: This randomised feasibility study has been designed to test all the required research procedures and additionally explore three key issues; the feasibility of implementing a complex trial at participating NHS T3WMS, training the multidisciplinary healthcare teams in a standard intervention, and the acceptability of a group intervention for these particularly complex patients. TRIAL REGISTRATION: ISRCTN number 22088800.

Assessing the fidelity of the independently getting up off the floor (IGO) technique as part of the ReTrain pilot feasibility randomised controlled trial for stroke survivors.

PURPOSE: Hemiparesis and physical deconditioning following stroke lead to an increase in falls, which many individuals cannot get up from. Teaching stroke survivors to independently get off the floor (IGO) might mitigate long-lie complications. IGO was taught as part of a community-based, functional rehabilitation training programme (ReTrain). We explore the feasibility of teaching IGO and assess participant's level of mastery, adherence, and injury risk. MATERIALS AND METHODS: Videos of participants (n = 17) performing IGO at early, middle, and late stages of the ReTrain programme were compared to a manualised standard. A visual, qualitative analysis was used to assess technique mastery, adherence, and injury risk. RESULTS: Most participants (64%) achieved independent, safe practice of IGO. A good (73%) level of adherence to IGO and low incidence of risk of injury (6.8%) were observed. Deviations were made to accommodate for non-stroke related comorbidities. CONCLUSIONS: IGO was successfully and safely practised by stroke survivors including those with hemiparesis. Trainers should be aware of comorbidities that may impede completion of IGO and modify teaching to accommodate individual need. Further research should assess if IGO can be utilised by individuals who have other disabilities with unilateral impairments and whether IGO has physical, functional and economic benefit.Implications for rehabilitationFalls are common in stroke survivors, and many are unable to get up despite being uninjured, leading to long-lie complications or ambulance call-outs but non-conveyance to hospital.Teaching the independently getting up off the floor (IGO) technique to stroke survivors was possible for those with or without hemiparesis, and remained safe despite modifications to accommodate an individual's needs.Individual assessment is needed to check if a stroke survivor is suitable for learning IGO including, but not limited to, their ability to safely get to the floor and to temporarily stand (without support) at the end of the technique.

The effectiveness of inpatient consultation-liaison psychiatry service models: A systematic review of randomized trials.

OBJECTIVE: To systematically review randomized trials of the effectiveness of inpatient Consultation-Liaison (C-L) Psychiatry service models in improving patient outcomes, reducing length of hospital stay and decreasing healthcare costs. METHOD: We searched databases including Ovid Medline, Ovid Embase, Ovid PsycINFO and EBSCO CINAHL for relevant trials. Two independent reviewers assessed articles and extracted data. The review is registered with PROSPERO, number CRD42019120827. RESULTS: Eight trials were eligible for inclusion. All had methodological limitations and all were published more than ten years ago. None reported clear evidence that the C-L Psychiatry service model evaluated was more effective than usual medical care alone. All the service models tested focused on providing a consultation for patients identified by screening. Clinical heterogeneity precluded meta-analysis. CONCLUSION: Whilst we found no evidence that any of the inpatient C-L Psychiatry service models evaluated is effective, the sparseness of the literature and its methodological limitations preclude strong conclusions. The trials do, however, suggest that purely consultation-based service models may not be effective. A new generation of robust clinical trials of a wider range of C-L Psychiatry service models is now required to inform future service developments.

Ecological momentary assessment of mood and physical activity in people with depression.

BACKGROUND: This study aimed to examine temporal associations between physical activity and subsequent mood in people with moderate to severe depression. METHODS: The study used ecological momentary assessment to associate mood, measured via text messaging twice daily for five days, using a 10-point Likert scale, with objectively measured physical activity (accelerometer data) in people with moderate-to-severe depression. Multilevel regression models were used to explore the relationship between physical activity undertaken at different intensities over the previous one and three hours, and subsequent affect score. A total of 388 paired data points were collected from 43 participants. RESULTS: There was no association between minutes of moderate-vigorous physical activity in the previous hour and subsequent affect score (which we had hypothesised). However, exploratory analyses found a significant relationship between affect and combined physical activity in the previous hour (ß1 coefficient = 0.023, p = 0.037). LIMITATIONS: Periods of moderate-vigorous activity were infrequent, reducing the statistical power for analysing associations with this intensity of activity. Only one dimension of mood was sampled. CONCLUSIONS: The data suggest that, in people with moderate-to-severe depression, time spent engaging in any intensity of physical activity was significantly associated with subsequent mood. Further research is needed to more clearly define the dynamics of the relationship between physical activity and low mood. This will aid identification of optimal prescription criteria for physical activity in people with depression.

Physical activity, sleep, and fatigue in community dwelling Stroke Survivors.

Stroke can lead to physiological and psychological impairments and impact individuals' physical activity (PA), fatigue and sleep patterns. We analysed wrist-worn accelerometry data and the Fatigue Assessment Scale from 41 stroke survivors following a physical rehabilitation programme, to examine relationships between PA levels, fatigue and sleep. Validated acceleration thresholds were used to quantify time spent in each PA intensity/sleep category. Stroke survivors performed less moderate to vigorous PA (MVPA) in 10 minute bouts than the National Stroke guidelines recommend. Regression analysis revealed associations at baseline between light PA and fatigue (p = 0.02) and MVPA and sleep efficiency (p = 0.04). Light PA was positively associated with fatigue at 6 months (p = 0.03), whilst sleep efficiency and fatigue were associated at 9 months (p = 0.02). No other effects were shown at baseline, 6 or 9 months. The magnitude of these associations were small and are unlikely to be clinically meaningful. Larger trials need to examine the efficacy and utility of accelerometry to assess PA and sleep in stroke survivors.

Community-based rehabilitation training after stroke: results of a pilot randomised controlled trial (ReTrain) investigating acceptability and feasibility.

OBJECTIVES: To assess acceptability and feasibility of trial processes and the Rehabilitation Training (ReTrain) intervention including an assessment of intervention fidelity. DESIGN: A two-group, assessor-blinded, randomised controlled trial with parallel mixed methods process and economic evaluations. SETTING: Community settings across two sites in Devon. PARTICIPANTS: Eligible participants were: 18 years old or over, with a diagnosis of stroke and with self-reported mobility issues, no contraindications to physical activity, discharged from National Health Service or any other formal rehabilitation programme at least 1 month before, willing to be randomised to either control or ReTrain and attend the training venue, possessing cognitive capacity and communication ability sufficient to participate. Participants were individually randomised (1:1) via a computer-generated randomisation sequence minimised for time since stroke and level of functional disability. Only outcome assessors independent of the research team were blinded to group allocation. INTERVENTIONS: ReTrain comprised (1) an introductory one-to-one session; (2) ten, twice-weekly group classes with up to two trainers and eight clients; (3) a closing one-to-one session, followed by three drop-in sessions over the subsequent 3 months. Participants received a bespoke home-based training programme. All participants received treatment as usual. The control group received an exercise after stroke advice booklet. OUTCOME MEASURES: Candidate primary outcomes included functional mobility and physical activity. RESULTS: Forty-five participants were randomised (ReTrain=23; Control=22); data were available from 40 participants at 6 months of follow-up (ReTrain=21; Control=19) and 41 at 9 months of follow-up (ReTrain=21; Control=20). We demonstrated ability to recruit and retain participants. Participants were not burdened by the requirements of the study. We were able to calculate sample estimates for candidate primary outcomes and test procedures for process and health economic evaluations. CONCLUSIONS: All objectives were fulfilled and indicated that a definitive trial of ReTrain is feasible and acceptable. TRIAL REGISTRATION NUMBER: NCT02429180; Results.
