Psychological flexibility is associated with less diabetes distress and lower glycated haemoglobin in adults with type 1 diabetes

Impact of an Acceptance and Commitment Therapy programme on HbA1c, self-management and psychosocial factors in adults with type 1 diabetes and elevated HbA1c levels: a randomised controlled trial

OBJECTIVE

To evaluate the impact of an Acceptance and Commitment Therapy (ACT) programme, tailored for people living with type 1 diabetes, on glycated haemoglobin (HbA1c), self-management and psychosocial factors among individuals with HbA1c>60 mmol/mol compared with treatment as usual (TAU).

SETTING

An endocrinologic clinic in Sweden.

PARTICIPANTS

In this randomised controlled trial, 81 individuals with type 1 diabetes, aged 18-70 years with HbA1c>60 mmol/mol, were randomly assigned to either an ACT group intervention or TAU. Exclusion criteria were: unable to speak Swedish, untreated or severe psychiatric disease, cortisone treatment, untreated thyroid disease and newly started insulin pump therapy. At the 2-year follow-up, HbA1c was measured in 26 individuals.

INTERVENTION

The ACT programme comprised seven 2-hour sessions held over 14 weeks and focused on acceptance of stressful thoughts and emotions, and to promote value-based committed action.

OUTCOMES

The primary outcome was HbA1c, and the secondary outcomes were measures of depression, anxiety, general stress, fear of hypoglycaemia, diabetes distress, self-care activities, psychological flexibility (general and related to diabetes) and quality of life. The primary endpoint was HbA1c 2 years after the intervention programme. Linear mixed models were used to test for an interaction effect between measurement time and group.

RESULTS

Likelihood ratio test of nested models demonstrated no statistically significant interaction effect (χ2=0.49, p=0.485) between measurement time and group regarding HbA1c. However, a statistically significant interaction effect (likelihood ratio test χ2=12.63, p<0.001) was observed with improved scores on The Acceptance and Action Questionnaire in the intervention group after 1 and 2 years.

CONCLUSIONS

No statistically significant difference was found between the groups regarding the primary outcome measure, HbA1c. However, the ACT programme showed a persistent beneficial impact on psychological flexibility in the intervention group. The dropout rate was higher than expected, which may indicate a challenge in this type of study.

An online acceptance, commitment, and self-compassion based treatment to decrease psychological distress in people with type 2 diabetes: A feasibility randomised-controlled trial

Background and purpose

This study explored the feasibility and acceptability of conducting a larger trial of a self-guided, online self-compassion and acceptance and commitment therapy (ACT) focused treatment among people with type 2 diabetes (T2D) to decrease psychological distress.

Materials and methods

This study was a two-arm, parallel, feasibility randomised controlled trial with nested qualitative methods. UK adults with T2D were randomly (1:1) allocated to a five-week online self-compassion and ACT treatment or waitlist control. Information regarding recruitment, trial retention, and treatment completion was collected, and post-treatment semi-structured interviews were conducted to assess feasibility and acceptability. Self-report measures of psychological distress (depression, anxiety, diabetes distress) and potential treatment processes (self-compassion and psychological flexibility) were completed as secondary feasibility outcomes.

Results

Fifty-five (60.44 %) out of 91 people who accessed the study link were eligible to participate. Of these, 33 eligible participants (60 %) were randomly assigned to treatment (n = 19) or control arms (waitlist; n = 14). While treatment completion was 47.37 %, trial retention rates were 39.39 % (5-week follow-up) and 21.2 % (9-week follow-up). Secondary feasibility outcomes of treatment effect estimates are difficult to interpret in light of low treatment completion and trial retention rates.

Conclusion

A larger trial of the self-guided, online self-compassion treatment to decrease psychological distress in people with T2D may be beneficial, but it has limited feasibility in its current form. Further efforts are needed to improve treatment acceptability of online self-compassion and ACT focused treatment and trial procedures.

A 12-month longitudinal study examining the shared and unique contributions of self-compassion and psychological inflexibility to distress and quality of life in people with Type 2 Diabetes

OBJECTIVES

Self-compassion and psychological flexibility appear to benefit wellbeing and quality of life (QoL) in the general population and in people with long-term conditions like Type 2 Diabetes (T2D). However, both variables share similarities and their unique roles in relation to distress and QoL in people with diabetes over time are not clear.

DESIGN

This was a longitudinal study with online assessments of self-compassion, psychological inflexibility, distress (depression, anxiety, diabetes-distress), and QoL at baseline (T1) and six (T2) and 12 months (T3).

METHODS

In total, 173 UK adults with T2D completed baseline questionnaires; T2 and T3 follow-ups were completed by 82 and 52 participants, respectively. Correlations were conducted to understand the relationships between variables at each time point. Hierarchical regressions were conducted to understand the unique predictive role of baseline self-compassion and psychological inflexibility in relation to distress and QoL at T2 and T3, controlling for age and baseline distress and QoL.

RESULTS

There were large significant negative correlations between self-compassion and psychological inflexibility (r > -0.50), and both had significant large correlations with distress (r > -0.50) but not QoL across time points. Regressions indicated that psychological inflexibility uniquely predicted depression (T2) and anxiety symptoms (T2 and T3) and QoL (T3). Self-compassion did not uniquely predict any of the outcomes.

CONCLUSIONS

Psychological inflexibility may play an important role in distress in T2D, but prospective studies with larger samples are needed to replicate these findings. Given the overlap between psychological inflexibility and self-compassion, treatments targeting either variable may be useful.
