This study identifies the frequency of severe hypoglycaemia as the most important factor associated with fear of hypoglycaemia. Moreover, for the first time, we document gender differences in fear of hypoglycaemia, suggesting that females are more affected by fear of hypoglycaemia than men.

Summary Aims To investigate fear of hypoglycaemia (FoH) longitudinally in a cross‐sectional study of adult patients with type 1 diabetes. Specifically, we investigated two subgroups of patients who over 4 years either showed a substantial increase or decrease in level of FoH to identify factors associated with changes in FoH. Methods The Swedish version of the Hypoglycaemia Fear Survey (HFS) along with a questionnaire to assess hypoglycaemia history was sent by mail to 764 patients in 2010. The responders in 2010 (n = 469) received another set of the same two questionnaires in 2014. HbA1c, insulin regimen, weight and creatinine from 2010 and 2014 were obtained from medical records. Those with an absolute difference in HFS scores ≥ 75th percentile were included in the subgroup analyses. Statistical analyses included one‐sample t tests, chi‐square and McNemar's test. Results The absolute difference in the HFS total score (n = 347) between 2010 and 2014 was m = ±7.6, SD ± 6. In the increased FoH group, more patients reported a high level of moderate hypoglycaemic episodes as well as impaired awareness of hypoglycaemia in 2014 compared with the decreased FoH group. There were more subjects in the increased FoH group with insulin pumps in 2014 and in 2010. In the decreased FoH group, more patients had a high frequency of daily self‐monitoring of blood glucose (SMBG) in 2010 and in 2014. Conclusions Fear of hypoglycaemia is stable across time for most patients. Changes in fear level are associated with changes in hypoglycaemia frequency. Thus, asking patients about changes in hypoglycaemia experiences is of great importance.

IntroductionIntegrating diabetes self-management into daily life involves a range of complex challenges for affected individuals. Environmental, social, behavioural and emotional psychological factors influence the lives of those with diabetes. The aim of this study is to evaluate the impact of a stress management group intervention based on acceptance and commitment therapy (ACT) among adults living with poorly controlled type 1 diabetes.Methods and analysisThis study will use a randomised controlled trial design evaluating treatment as usual (TAU) and ACT versus TAU. The stress management group intervention will be based on ACT and comprises a programme divided into seven 2-hour sessions conducted over 14 weeks. A total of 70 patients who meet inclusion criteria will be recruited over a 2-year period with follow-up after 1, 2 and 5 years.The primary outcome measure will be HbA1c. The secondary outcome measures will be the Depression Anxiety Stress Scales, the Swedish version of the Hypoglycemia Fear Survey, the Swedish version of the Problem Areas in Diabetes Scale, The Summary of Self-Care Activities, Acceptance Action Diabetes Questionnaire, Swedish Acceptance and Action Questionnaire and the Manchester Short Assessment of Quality of Life. The questionnaires will be administered via the internet at baseline, after sessions 4 (study week 7) and 7 (study week 14), and 6, 12 and 24 months later, then finally after 5 years. HbA1c will be measured at the same time points.Assessment of intervention effect will be performed through the analysis of covariance. An intention-to-treat approach will be used. Mixed-model repeated measures will be applied to explore effect of intervention across all time points.Ethics and disseminationThe study has received ethical approval (Dnr: 2016/14-31/1). The study findings will be disseminated through peer-reviewed publications, conferences and reports to key stakeholders.Trial registration numberNCT02914496; Pre-results.

70minant subdomain may be considered. We suggest, however a one-factor model covering all the items as a relevant basis to assess fear of complications among people with Type 1 diabetes.
