Graves H, Garrett C, Amiel SA, Ismail K, Winkley K. Psychological skills training to support diabetes self-management: Qualitative assessment of nurses' experiences. Prim Care Diabetes 2016; 10:376-382. [PMID: 27006306 DOI: 10.1016/j.pcd.2016.03.001] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2016] [Revised: 03/04/2016] [Accepted: 03/06/2016] [Indexed: 10/22/2022]
Abstract
AIM Evidence for the efficacy of psychological skills training as a method of supporting patients' self-management is growing, but there is a shortage of mental health providers with specialist diabetes knowledge to deliver them. Primary care nurses are now increasingly expected to learn and use these techniques. This study explores nurse experience of training in six psychological skills to support patients' self-management of type 2 diabetes. METHODS Semi-structured interviews elicited themes relating to nurses' experiences of participating in a trial of a psychological intervention, the Diabetes-6 study (D-6). Nurses were employed in GP surgeries in 5 South London boroughs. Thematic framework analysis was used to compare and contrast themes across participants. Nine nurses delivering the intervention (n=11), and 7 from the control intervention (n=12, no psychological element) were interviewed. RESULTS Three key themes were identified: (i) positive and negative impact of D6 on nurses' practice: positives included patient empowerment; negatives included patients' capacity to engage; (ii) professional boundaries including concerns about over-stepping role as a nurse and (iii) concerns about degree of support from physicians at participating practices in integrating psychological and diabetes care. CONCLUSION Primary care nurses report that psychological skills training can have a positive impact on patient care. Significant role adjustment is required, which may be aided by additional support from the practice team. Qualitative evaluation of effectiveness of psychological interventions may reveal processes that hinder or contribute to efficacy and translation. Appropriate support is necessary for primary care nurses to deliver psychological therapies with confidence.

Abstract
We aimed to investigate the association between incretin-based therapies and 1-year change in depressive symptoms in a cohort of 1735 patients with newly diagnosed type 2 diabetes. The incretin group experienced significant reduction in depressive symptoms compared to controls. This was independent of HbA1c and may be mediated by an anti-inflammatory mechanism.

Abstract
OBJECTIVE The aims were to determine the association between individual and neighbourhood factors and attendance at structured education amongst people with newly diagnosed type 2 diabetes (T2DM). METHODS Multi-level analysis of questionnaire data from a prospective cohort of adults newly diagnosed T2DM. Setting was primary care, London, UK. Main outcome was attendance at structured education within 2 years. RESULTS Of 1790 people recruited, attendance data were available for 1626 (91%). Only 22.4% (n=365/1626) attended education. Attendance was independently associated with female gender (OR 1.28, 95% CI 1.05-1.46), lower HbA1c (OR 0.98 mmol/mol 95% CI 0.97-0.99) and non-smoker status (OR 1.36, 95% CI 1.07-1.55). General practice covariates, achievement of primary care targets for glycaemic control (OR 1.05, 95% C.I. 1.01-1.08) and recording of retinal screening (OR 0.96, 95% C.I. 0.93-0.99) were independently associated with attendance but unexplained general practice clustering accounted for 17% of the variance. CONCLUSION Education uptake is low amongst people with new onset T2DM. Attenders are more likely to be female, non-smokers with better HbA1c. General practices achieving glycaemic targets are more likely to have patients who attend education. PRACTICE IMPLICATIONS Strategies are needed to improve attendance at structured diabetes education particularly amongst hard to reach groups.

Comparing the effectiveness of an enhanced MOtiVational intErviewing InTervention (MOVE IT) with usual care for reducing cardiovascular risk in high risk subjects: study protocol for a randomised controlled trial. Trials 2015; 16:112. [PMID: 25886569 PMCID: PMC4399238 DOI: 10.1186/s13063-015-0593-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2014] [Accepted: 02/06/2015] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Interventions targeting multiple risk factors for cardiovascular disease (CVD), including poor diet and physical inactivity, are more effective than interventions targeting a single risk factor. A motivational interviewing (MI) intervention can provide modest dietary improvements and physical activity increases, while adding cognitive behaviour therapy (CBT) skills may enhance the effects of MI. We designed a randomised controlled trial (RCT) to examine whether specific behaviour change techniques integrating MI and CBT result in favourable changes in weight and physical activity in those at high risk of CVD. A group and individual intervention will be compared to usual care. A group intervention offers potential benefits from social support and may be more cost effective. METHODS/DESIGN Individuals aged between 40 and 74 years in 11 South London Clinical Commissioning Groups who are at high risk of developing CVD (≥20%) in the next 10 years will be recruited. A sample of 1,704 participants will be randomised to receive the enhanced MI intervention, delivered by trained healthy lifestyle facilitators (HLFs), in group or individual formats, in 10 sessions (plus an introductory session) over one year, or usual care. Randomisation will be conducted by King's College London Clinical Trials Unit and researchers collecting outcome data will be blinded to treatment allocation. At 12-month and 24-month follow-up assessments, primary outcomes will be change in weight and physical activity (average steps per day). Secondary outcomes include changes in low-density lipoprotein cholesterol and CVD risk score. Incidence of CVD events since baseline will be recorded. A process evaluation will be conducted to evaluate factors which impact on delivery, adherence and outcome. An economic evaluation will estimate relative cost-effectiveness of each type of intervention delivery. DISCUSSION This RCT assesses the effectiveness of a healthy lifestyle intervention for people at high risk of CVD. Benefits of the study include the ethnic and socioeconomic diversity of the study population and that, via social support within the group setting and long-term follow-up period, the intervention offers the potential to support maintenance of a healthy lifestyle. TRIAL REGISTRATION This trial is registered with the ISRCTN registry (identifier: ISRCTN84864870, registered 15 May 2012).

Abstract
AIM To determine the reasons for non-attendance at structured education sessions among people with a recent diagnosis of Type 2 diabetes. METHODS This was a qualitative study using semi-structured interviews to elicit the main themes explaining non-attendance. A thematic framework method was applied to analyse the data. People who had not attended structured education were recruited from a population cohort of newly diagnosed Type 2 diabetes from South London (the South London Diabetes cohort study), UK. RESULTS A sample of 30 people was interviewed. Three main themes emerged from the qualitative data explaining non-attendance at structured education: (1) lack of information/perceived benefit of the programme (e.g. not being informed about the course by their health professional); (2) unmet personal preferences (e.g. parking, timing); and (3) shame and stigma of diabetes (e.g. not wishing to tell others of diabetes diagnosis). CONCLUSION This is the first time that reasons for non-attendance have been explored in depth among people who have newly diagnosed Type 2 diabetes. Novel reasons identified included non-attendance because of shame and stigma of diabetes. To improve uptake at structured education we need to: consider how health professionals in primary care communicate with their patients on the subject of structured diabetes education; offer alternatives to the traditional group education format; and understand that diabetes is associated with health-related stigma, which may affect participation.

Abstract
Background. WHO's recommendation of HbA1c ≥ 48 mmol/mol (6.5%) as diagnostic for type 2 diabetes mellitus (T2DM) was adopted by three UK London boroughs in May 2012. The South London Diabetes (SOUL-D) study has recruited people with newly diagnosed T2DM since 2008. We compared participants diagnosed before May 2012 with HbA1c < 48 mmol/mol to those with diagnostic HbA1c ≥ 48 mmol/mol. Methods. A prospective cohort study of newly diagnosed T2DM participants from 96 primary care practices, comparing demographic and biomedical variables between those with diagnostic HbA1c < 48 mmol/mol or HbA1c ≥ 48 mmol/mol at recruitment and after one year. Results. Of 1488 participants, 22.8% had diagnostic HbA1c < 48 mmol/mol. They were older and more likely to be white (p < 0.05). At recruitment and one year, there were no between-group differences in the prevalence of diabetic complications, except that those diagnosed with HbA1c < 48 mmol/mol had more sensory neuropathy at recruitment (p = 0.039) and, at one year, had new myocardial infarction (p = 0.012) but less microalbuminuria (p = 0.012). Conclusions. Use of HbA1c ≥ 48 mmol/mol as the sole T2DM diagnostic criterion may miss almost a quarter of those previously diagnosed in South London yet HbA1c < 48 mmol/mol may not exclude clinically important diabetes.

Abstract
OBJECTIVE We aim to systematically review observational studies examining the association between social support and glycemic control in adults with type 2 diabetes. METHODS We searched MEDLINE, PsycINFO, EMBASE, Scopus, Web of Science and Sociological Abstracts to July 2012 for observational studies investigating the association between structural or functional aspects of social support (social networks, community ties, marital status, family support, perceived, actual, emotional or instrumental social support) and glycemic control (HbA1c). RESULTS From electronic and reference searches, 29 studies were eligible. Twenty different assessments of social support were used. Family support and composite measures of support were most frequently associated with reduced HbA1c. There was no evidence for a beneficial effect of other support measures on HbA1c. CONCLUSION We found marked variation in population, setting, measurement of social support and definition of outcome, limiting the methodological validity of research. Social support may be important in the management of type 2 diabetes, the need for consensus and standardization of measures is highlighted. PRACTICE IMPLICATIONS The presence of informal support should be explored in routine diabetes care.

Abstract
AIMS/HYPOTHESIS This study aimed to investigate the clinical features of newly diagnosed type 2 diabetes in an urban multi-ethnic cohort. METHODS A population-based cross-sectional design was used. People diagnosed with type 2 diabetes in the preceding 6 months were recruited from primary care practices in three adjacent inner-city boroughs of South London, serving a population in which 20% of residents are of black African or Caribbean ethnicity. Sociodemographic and biomedical data were collected by standardised clinical assessment and from medical records. Multiple logistic regression methods were used to report associations between ethnicity and diabetes-complication status. RESULTS From 96 general practices, 1,506 patients were recruited. Their mean age was 55.6 (± 11.07) years, 55% were men, 60% were asymptomatic at diagnosis and 51%, 38% and 11% were of white, black and South Asian/other ethnicity, respectively. Compared with white participants, black and South Asian/other participants were: younger (mean age 58.9 [± 10.09], 52.4 [± 11.19] and 51.5 [± 10.42] years, respectively; p < 0.0001); less likely to have neuropathy (10.1%, 3.6% and 4.4%; p < 0.0001) or report coronary artery disease (12.7%, 4.8% and 7.3%; p < 0.0001). In logistic regression, compared with white participants, black participants had lower levels of macrovascular complications (OR 0.52, 95% CI 0.32, 0.84; p = 0.01). Male sex was independently associated with microvascular disease (OR 1.69, 95% CI 1.26, 2.28; p < 0.0001). CONCLUSIONS/INTERPRETATION The prevalence of complications at time of diagnosis was lower than expected, especially in black and South Asian/other ethnic groups. However, in multi-ethnic inner-city populations, onset of type 2 diabetes occurred almost 10 years earlier in non-white populations than in white participants, predicating a prolonged morbidity.

Abstract
AIMS/HYPOTHESIS Depressive disorders are associated with mortality within 18 months of presentation of diabetic foot ulcers (DFU). The main aim of this study was to determine whether depressive disorder is still associated with increased mortality in people with their first foot ulcer at 5 years. METHODS This is a 5-year follow-up of a cohort of 253 patients presenting with their first DFU. At baseline, the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) 2.1 was used to define those who met DSM-IV (Diagnostic and Statistical Manual 4th edition) criteria for depressive disorder. Cox regression analysis controlled for potential covariates: age, sex, marital status, socioeconomic status, smoking, mean HbA(1c), diabetes complications and ulcer severity. The main outcome was mortality at 5 years. RESULTS The prevalence of DSM-IV depressive disorder at baseline was 32.2% (n = 82). There were 92 (36.4%) deaths over the 5 years of follow-up. In the Cox regression (n = 246), after adjusting for covariates, baseline DSM-IV depressive disorder was significantly associated with a twofold increased risk of mortality for any depressive episode (HR 2.09, 95% CI 1.34, 3.25), minor (HR 1.93, 95% CI 1.00, 3.74) or major depressive disorders (HR 2.18, 95% CI 1.31, 3.65), compared with patients who were not depressed. CONCLUSIONS/INTERPRETATION Depression is associated with a persistent twofold increased risk of mortality in people with their first DFU at 5 years.

Abstract
OBJECTIVE Meta-analyses have shown that the risk for depression is elevated in type 2 diabetes. Whether this risk in individuals with impaired glucose metabolism (IGM) or undiagnosed diabetes (UDD) is elevated relative to normal glucose metabolism (NGM) or decreased relative to previously diagnosed type 2 diabetes (PDD) has not been the subject of a systematic review/meta-analysis. This study examined the prevalence of depression in IGM and UDD subjects relative to each other and to NGM and PDD subjects by reviewing the literature and conducting a meta-analysis of studies on this topic. RESEARCH DESIGN AND METHODS EMBASE and MEDLINE databases were searched for articles published up to May 2010. All studies that compared the prevalence of depression in subjects with IGM and UDD were included. Odds ratios (ORs) were calculated using fixed and random-effects models. RESULTS The meta-analysis showed that the risk for depression was not increased in IGM versus NGM subjects (OR 0.96, 95% CI 0.85-1.08). Risk for depression did not differ between individuals with UDD and individuals with either NGM (OR 0.94, 95% CI 0.71-1.25) or IGM (OR 1.16, 95% CI 0.88-1.54). Finally, individuals with IGM or UDD both had a significantly lower risk of depression than individuals with PDD (OR 0.59, 95% CI 0.48-0.73, and OR 0.57, 95% CI 0.45-0.74, respectively). CONCLUSIONS Results of this meta-analysis show that the risk of depression is similar for NGM, IGM, and UDD subjects. PDD subjects have an increased risk of depression relative to IGM and UDD subjects.

Abstract
AIMS/HYPOTHESIS An earlier meta-analysis showed that diabetes is a risk factor for the development and/or recurrence of depression. Yet whether this risk is different for studies using questionnaires than for those relying on diagnostic criteria for depression has not been examined. This study examined the association of diabetes and the onset of depression by reviewing the literature and conducting a meta-analysis of longitudinal studies on this topic. METHODS EMBASE, MEDLINE and PsycInfo were searched for articles published up to September 2009. All studies that examined the relationship between type 2 diabetes and the onset of depression were included. Pooled relative risks were calculated using fixed and random effects models. RESULTS Eleven studies met our inclusion criteria for this meta-analysis. Based on the pooled data, including 48,808 cases of type 2 diabetes without depression at baseline, the pooled relative risk was 1.24 (95% CI 1.09-1.40) for the random effects model. This risk was significantly higher for studies relying on diagnostic criteria of depression than for studies using questionnaires. However, this difference was no longer significant when controlled for year of publication. CONCLUSIONS/INTERPRETATION Compared with non-diabetic controls, people with type 2 diabetes have a 24% increased risk of developing depression. The mechanisms underlying this relationship are still unclear and warrant further research.

Abstract
The prevalence of chronic non-communicable disease, such as type 2 diabetes mellitus (T2DM), is rising worldwide. In Africa, T2DM is primarily affecting those living in urban areas and increasingly affecting the poor. Diabetes management among urban poor is an area of research that has received little attention. Based on ethnographic fieldwork in Dar es Salam, the causes and conditions for diabetes management in Tanzania have been examined. In this paper, we focus on the structural context of diabetes services in Tanzania; the current status of biomedical and ethnomedical health care; and health-seeking among people with T2DM. We demonstrate that although Tanzania is actively developing its diabetes services, many people with diabetes and low socioeconomic status are unable to engage continuously in treatment. There are many challenges to be addressed to support people accessing diabetes health care services and improve diabetes management.

Abstract
BACKGROUND People with diabetic foot ulcers report poor quality of life. However, prospective studies that chart quality of life from the onset of diabetic foot ulcers are lacking. We describe change in quality of life in a cohort of people with diabetes and their first foot ulcer during 18 months and its association with adverse outcomes. METHODS In this prospective cohort study of adults with their first diabetic foot ulcer, the main outcome was change in Medical Outcomes Study 36-Item Short Form Health Survey scores between baseline and 18-month follow-up. We recorded baseline demographics, diabetes characteristics, depression, and diabetic foot outcomes and mortality at 18 months. RESULTS In 253 people with diabetes and their first ulcer, there were 40 deaths (15.8%), 36 amputations (15.5%), 99 recurrences (43.2%), and 52 nonhealing ulcers (21.9%). The 36-Item Short Form Health Survey response rate of survivors at 18 months was 78% (n = 157). There was a 5- to 6-point deterioration in mental component summary scores in people who did not heal (adjusted mean difference, -6.54; 95% confidence interval, -12.64 to -0.44) or had recurrent ulcers (adjusted mean difference, -5.30; 95% confidence interval, -9.87 to -0.73) and a nonsignificant reduction in those amputated (adjusted mean difference, -5.00; 95% confidence interval, -11.15 to 1.14). CONCLUSIONS Quality of life deteriorates in people with diabetes whose first foot ulcer recurs or does not heal within 18 months.

Abstract
OBJECTIVE To update a meta-analysis and determine the effectiveness of psychological interventions on glycaemic control measured by HbA(1c) and psychological status in type 2 diabetes and to compare effects when interventions are delivered by generalist clinicians compared to psychological specialists. METHODS We used the original review protocol and searched the Cochrane central register of controlled trials, Medline, Embase, PsychLIT, and Google Scholar from February 2003 (end of previous review) to March 2007. We extracted data on the participants, interventions, delivery methods, comparison groups and outcome measures. RESULTS 35 trials were reviewed and meta-analysis of 19 trials (n=1431), reporting HbA(1c) found a reduction in HbA(1c) by 0.54% (-0.32; 95% CI: -0.47 to -0.16). In nine trials (n=832) interventions were delivered by diabetes or general clinicians reducing HbA(1c) by 0.51% (-0.27; 95% CI: -0.50 to 0.04). In nine trials, interventions (n=561) were delivered by psychological specialists reducing HbA(1c) by 0.57% (-0.36; 95% CI: -0.61 to 0.12). Meta-analysis of 13 trials reporting psychological status found psychological status to be lower in the intervention groups -0.56 (95% CI: 1.00 to -0.13). Trial quality for the majority of studies remained poor. CONCLUSION Our findings suggest that psychological and general clinicians are similarly effective in delivering psychological interventions, however, effect sizes for all clinicians have reduced since the earlier review. PRACTICE IMPLICATIONS Psychological training opportunities for generalist clinicians could lead to wider availability of effective psychological care.

J Diabetes Complications 2007; 21:341-9.

Abstract
AIMS/HYPOTHESIS The aim of this study was to determine which clinic-based measures of diabetes and foot status at baseline were associated with adverse outcomes 18 months later in people with diabetes presenting with their first foot ulcer. SUBJECTS AND METHODS This was a prospective population-based cohort study of adults with type 1 and type 2 diabetes mellitus presenting with their first foot ulcer (excluding those with severe ischaemia, ankle brachial pressure index <0.5). The main explanatory variables were age, sex, smoking status, ulcer site (dorsal or plantar), size and severity of ulcer, severity of neuropathy, ischaemia, glycosylated haemoglobin, presence of micro- and macrovascular complications, and depression. The main outcomes recorded were death, amputation and recurrence of ulceration, and the time taken for each outcome to occur. RESULTS Two hundred fifty-three people were recruited. There were 40 deaths (15.8%), 36 amputations (15.5%), and 99 recurrences (43.2%) at 18 months. Our main findings were that being older [hazard ratio (HR) 1.07, 95% CI 1.04-1.11], having lower glycosylated haemoglobin (HR 0.73, 95% CI 0.56-0.96), moderate ischaemia (HR 2.74, 95% CI 1.46-5.14), and depression (HR 2.51, 95% CI 1.33-4.73) were associated with mortality. Ulcer severity was the only explanatory factor significantly associated with amputation (HR 3.18, 95% CI 1.53-6.59). Microvascular complications were the only explanatory factor associated with recurrent ulceration (HR 3.34, 95% CI 1.17-9.56). CONCLUSIONS/INTERPRETATION Commonly used primary and secondary care clinic-based measures could provide the basis for a risk assessment tool for adverse outcomes following first presentation of diabetic foot ulcers.

Abstract
OBJECTIVE The aim was to evaluate over 18 months whether depression was associated with mortality in people with their first foot ulcer. RESEARCH DESIGN AND METHODS A prospective cohort design was used. Adults with their first diabetic foot ulcer were recruited from foot clinics in southeast London, U.K. At baseline, the Schedules for Clinical Assessment in Neuropsychiatry 2.1 was used to define those who met DSM (Diagnostic and Statistical Manual of Mental Disorders)-IV criteria for minor and major depressive disorders. Potential covariates were age, sex, marital status, socioeconomic status, smoking, antidepressant use, A1C, macro- and microvascular complications, and University of Texas classification-based severity and size of ulcer. The main outcome was mortality 18 months later, and A1C was the secondary outcome. The proportion who had an amputation, had recurrence, and whose ulcer had healed was recorded. RESULTS A total of 253 people with their first diabetic foot ulcer were recruited. The prevalence of minor and major depressive disorder was 8.1% (n = 21) and 24.1% (n = 61), respectively. There were 40 (15.8%) deaths, 36 (15.5%) amputations, and 99 (43.2%) recurrences. In the adjusted Cox regression analysis, minor and major depressive disorders were associated with an approximately threefold hazard risk for mortality compared with no depression (3.23 [95% CI 1.39-7.51] and 2.73 [1.38-5.40], respectively). There was no association between minor and major depression compared with no depression and A1C (P = 0.86 and P = 0.43, respectively). CONCLUSIONS One-third of people with their first diabetic foot ulcer suffer from clinical depression, and this is associated with increased mortality.

Abstract
OBJECTIVE To determine whether psychological interventions have any effect on glycaemic control in people with type 1 diabetes. DESIGN Systematic review and meta-analysis of psychological therapies to assess their effectiveness in improving glycaemic control in type 1 diabetes. DATA SOURCES Medline, PsycINFO, Embase, and Cochrane central register of controlled trials searched to September 2004. REVIEW METHODS All included studies were randomised controlled trials in children (including adolescents) or adults with type 1 diabetes that evaluated the effect of a psychological therapy (counselling, cognitive behaviour therapy, family systems therapy, and psychodynamic therapy) on control of diabetes. Data were extracted on sample size, age, duration of diabetes, type of psychological therapy, its mode of delivery, and type of intervention in control group. MAIN OUTCOME MEASURES Glycaemic control measured by percentage of glycated haemoglobin and psychological distress. Pooled standardised effect sizes were calculated. RESULTS 29 trials were eligible for the systematic review and 21 trials for the meta-analysis. In the 10 studies of children and adolescents included in the meta-analysis, the mean percentage of glycated haemoglobin was significantly reduced in those who had received a psychological intervention compared with those in the control group (pooled standardised mean difference -0.35 (95% confidence interval -0.66 to -0.04), equivalent to a 0.48% (0.05% to 0.91%) absolute reduction in glycated haemoglobin. In the 11 studies in adults the pooled standardised mean difference was -0.17 (-0.45 to 0.10), equivalent to 0.22% (-0.13% to 0.56%) absolute reduction in glycated haemoglobin. Psychological distress was significantly lower in the intervention groups in children and adolescents (pooled standardised effect size -0.46, -0.83 to -0.10) but not in adults (-0.25, -0.51 to 0.01). CONCLUSION Psychological treatments can slightly improve glycaemic control in children and adolescents with diabetes but have no effect in adults.

Abstract
BACKGROUND Adherence difficulties and psychological problems are associated with poor glycaemic control in diabetes. We undertook a systematic review and meta-analysis of psychological therapies to assess their effectiveness in improving glycaemic control in type 2 diabetes. METHODS We searched MEDLINE, PsychINFO, EMBASE, and the Cochrane Central Register of Controlled Trials up to January, 2003. Eligible studies were randomised controlled trials that involved people with type 2 diabetes and evaluated a psychological therapy (counselling, cognitive behaviour therapy, or psychodynamic therapy) to improve diabetes control. We extracted the number of participants, their age, duration of diabetes, glycaemic control, type of psychological therapy, its mode of delivery, and type of intervention in the control group. The main outcome was long-term glycaemic control measured by percentage of glycated haemoglobin. Blood glucose concentration, weight, and psychological distress were also measured. Pooled standardised effect sizes were calculated. FINDINGS 25 trials were eligible for the review. In 12 trials, the mean percentage glycated haemoglobin was lower in people assigned a psychological intervention than in the control group (usual care, education, waiting list, or attention control); the pooled mean difference was -0.32 (95% CI -0.57 to -0.07) equivalent to an absolute difference of -0.76%. There were non-significant differences in blood glucose concentration (eight trials; -0.11 [-0.65 to 0.42]) and weight gain (nine trials; 0.37 [-0.18 to 0.93]). Psychological distress was significantly lower in the intervention groups (five trials; -0.58 [-0.95 to -0.20]). INTERPRETATION In type 2 diabetes, there are improvements in long-term glycaemic control and psychological distress but not in weight control or blood glucose concentration in people who receive psychological therapies.
