Ayling, Kieran / Brierley, Samantha / Johnson, Barbara / Heller, Simon / Eiser, Christine. ·Department of Psychology, University of Sheffield, UK; Division of Primary Care, School of Medicine, University of Nottingham, UK; NIHR CLAHRC for South Yorkshire, Sheffield, UK. ·Br J Health Psychol · Pubmed #25557718.

ABSTRACT: PURPOSE: Theory-based behaviour change interventions have been recommended to improve outcomes for young people with type 1 diabetes. However, theory has exclusively been considered in a simplistic all-or-none fashion. We therefore (1) examined the nature and extent of explicit theory use in published interventions involving young people with type 1 diabetes and (2) the relationship between how theory is used and intervention outcomes. METHODS: We conducted systematic searches for randomized controlled trials (RCTs) published between 1999 and 2012. We used a detailed structured framework to code how theory was used and meta-analytic techniques to examine the relationships between theory use and intervention efficacy. RESULTS: We identified 34 articles comprising 27 RCTs. Thirty per cent (k = 8) did not use theory in any of the ways assessed. Where present, the most common use of theory was providing evidence that a targeted theoretical construct predicted behaviour (k = 15; 56%). Trials that used theory to some extent had marginally larger pooled effect sizes for both medical and psychological outcomes than those that did not. However, in meta-regression models, use of theory did not significantly predict intervention outcomes. CONCLUSIONS: Theory is under-utilized in intervention development for young people with type 1 diabetes. When employed, theory appears to be advantageous, but not necessarily predictive of intervention success. We argue that greater emphasis is needed on choosing appropriate theory, which should then become central to the process of intervention development. Statement of contribution What is already known on this subject? Interventions for young people with type 1 diabetes that explicitly cite a theoretical basis may be more effective than those that do not. Recommendations have been made for theory to be central to the intervention development process in this area. What does this study add? Theory use in recent interventions for young people with type 1 diabetes is extremely limited. Larger positive medical and psychological outcomes are observed in interventions making some use of theory. Greater use of theory does not necessarily guarantee intervention success.

ABSTRACT: OBJECTIVE: Poor descriptions of standard care may compromise interpretation of results in randomised controlled trials (RCTs) of health interventions. We investigated quality of standard care in RCTs of behaviour change interventions for young people with type 1 diabetes and consider implications for evaluating trial outcomes. DESIGN: We conducted systematic searches for articles published between 1999 and 2012. We extracted standard care descriptions and contacted trial authors to complete a checklist of standard care activities. The relationship between standard care quality and outcomes was examined via subgroup meta-analyses and meta-regression. MAIN OUTCOME MEASURES: Standard care descriptions, standard care quality, and relationships between standard care quality with medical and psychological outcomes. RESULTS: We identified 20 RCTs described across 26 articles. Published descriptions of standard care were limited to service-level features. Author responses indicated standard care provision extended beyond published accounts. Subgroup analyses suggested control groups receiving higher standard care quality showed larger improvements in both medical and psychological outcomes, although standard care quality did not predict outcomes significantly. CONCLUSION: The quality of care delivered to control group participants can influence outcomes of RCTs. Inadequate reporting exacerbates this issue by masking variations between trials. We argue for increased clarity in reporting standard care in future trials.

3 Review Eating problems in adolescents with Type 1 diabetes: a systematic review with meta-analysis. 2013

Young, V / Eiser, C / Johnson, B / Brierley, S / Epton, T / Elliott, J / Heller, S. ·Department of Psychology, NIHR CLAHRC for South Yorkshire, Medical School, University of Sheffield, Sheffield, UK. v.young@sheffield.ac.uk ·Diabet Med · Pubmed #22913589.

ABSTRACT: AIMS: We report a systematic review to determine (1) prevalence of eating problems compared with peers and (2) the association between eating problems and glycaemic control in young adults with Type 1 diabetes. METHOD:   We conducted a systematic literature search via electronic databases and meta-analysis. Cohen's d (the mean difference score between Type 1 diabetes and comparison groups) was calculated for 13 studies that met inclusion criteria. RESULTS:   Eating problems [both disordered eating behaviour (39.3 and 32.5%; d = 0.52, 95% CI 0.10-0.94) and eating disorders (7.0 and 2.8%; d = 0.46, 95% CI 0.10-0.81)] were more common in adolescents with Type 1 diabetes compared with peers and both were associated with poorer glycaemic control (d = 0.40, 95% CI 0.17-0.64). In restricted analyses involving measures adapted for diabetes, associations between eating problems and poorer glycaemic control remained (d = 0.54, 95% CI 0.32-0.76). Disordered eating behaviour (51.8 and 48.1%; d = 0.06, 95% CI -0.05 to 0.21) and eating disorders (6.4 and 3.0%; d = 0.43, 95% CI -0.06 to 0.91) were more common in adolescents with Type 1 diabetes compared with peers, but differences were non-significant. CONCLUSIONS:   Eating problems are common among this age group. Future work in populations with Type 1 diabetes should develop sensitive measures of eating problems and interventions, and establish predictors of eating problems. Screening in clinics is recommended.

4 Review Prevalence of depression among young people with Type 1 diabetes: a systematic review. 2013

Johnson, B / Eiser, C / Young, V / Brierley, S / Heller, S. ·NIHR CLAHRC for South Yorkshire, Department of Psychology, University of Sheffield, Sheffield, UK. b.johnson@sheffield.ac.uk ·Diabet Med · Pubmed #22698387.

ABSTRACT: AIMS:   To determine: (1) prevalence of depression among young people with Type 1 diabetes compared with control groups or population norms; (2) implications of depression for HbA(1c) level; and (3) the relationship between history of depressive symptoms and future depressive symptoms. BACKGROUND:   Among adults with Type 1 diabetes depression is higher than the general population, and has been associated with adverse implications for self-care and HbA(1c) level. The last published review of depression among young people with Type 1 diabetes only included studies up to 1999. METHOD:   Systematic searches were conducted for articles published from January 1999 to December 2011 including young people (up to 25 years old) with Type 1 diabetes. RESULTS:   Twenty-three articles met the inclusion criteria. Of five studies that reported prevalence of depression compared with control groups, three found no differences. Of the three studies that investigated prevalence of depression making reference to population norms, all three showed higher rates of depressive symptoms. Fourteen of 15 studies found associations between more depressive symptoms and higher HbA(1c) level either cross-sectionally or longitudinally. Past depressive symptoms were associated with later depressive symptoms. CONCLUSIONS:   Current evidence is inconclusive about whether there is increased prevalence of depression among young adults with Type 1 diabetes, as established among adults, but those who are more depressed have higher HbA(1c) level. This review is limited by methodological problems and no identified work in the UK met the inclusion criteria. Given the adverse clinical outcomes, we conclude there is a case for routine mental health screening for young adults with Type 1 diabetes.

5 Article Using the Medical Research Council framework to develop a complex intervention to improve delivery of care for young people with type 1 diabetes. 2013

Eiser, C / Johnson, B / Brierley, S / Ayling, K / Young, V / Bottrell, K / Whitehead, V / Elliott, J / Scott, A / Heller, S. ·Department of Psychology, University of Sheffield, Sheffield, UK. c.eiser@sheffield.ac.uk ·Diabet Med · Pubmed #23510142.

ABSTRACT: AIMS: We describe how we have used the development phase of the Medical Research Council (MRC) Guidelines to construct a complex intervention to improve physical and psychological health among young people (16-21 years) with Type 1 diabetes. METHODS: We consulted previous reviews where available and conducted systematic searches of electronic databases to determine physical and mental health among the population, audited medical records, surveyed self-reported psychological health among our clinic population; and interviewed staff (n = 13), young people (n = 27) and parents (n = 18) about their views of current care. RESULTS: Our audit (n = 96) confirmed a high HbA1c [86 mmol/mol (10.0%)] and one third (36.1%) reported significant eating problems. Young people did not attend 12% of their clinic appointments. Staff described difficulties communicating with young people who wanted staff to take account of their individual lifestyle when giving information. CONCLUSION: Based on the findings of the systematic reviews and our audit, we concluded that there was sufficient evidence to justify development of a model of care specific to this age group. The components of the complex intervention include changes to standard care, an optional 5-day self-management course directed at young people and a separate family communication programme. The MRC Guidelines provided a valuable structure to guide development and evaluation of this intervention.

6 Article Working with young adults with Type 1 diabetes: views of a multidisciplinary care team and implications for service delivery. 2012

Brierley, S / Eiser, C / Johnson, B / Young, V / Heller, S. ·Department of Psychology Department of Human Metabolism, University of Sheffield, Sheffield NIHR CLAHRC for South Yorkshire, UK. s.brierley@sheffield.ac.uk ·Diabet Med · Pubmed #22375561.

ABSTRACT: AIMS: Young adults with Type 1 diabetes experience difficulties achieving glucose targets. Clinic attendance can be poor, although health and self-care tend to be better among those who attend regularly. Our aims were to describe staff views about challenges working with this age-group (16-21 years). METHODS: Semistructured interviews were conducted with 14 staff from Sheffield Teaching Hospitals diabetes care team. Interviews were audio-recorded, transcribed and analysed using thematic analysis. RESULTS: Three main themes emerged. Unique challenges working with young adults included staff emotional burden, the low priority given to self-care by young adults and the complexity of the diabetes regimen. Working in a multidisciplinary team was complicated by differences in consultation styles, poor team cohesion and communication. An ideal service should include psychological support for the professional team, identification of key workers, and development of individualized care plans. CONCLUSIONS: Staff differed in their views about how to achieve optimal management for young adults, but emphasized the need for greater patient-centred care and a range of interventions appropriate for individual levels of need. They also wanted to increase their own skills and confidence working with this age-group. While these results reflect the views of staff working in only one diabetes centre, they are likely to reflect the views of professionals delivering care to individuals of this age; replication is needed to determine their generalizability.
