An open trial of app-assisted acceptance and commitment therapy (iACT) for eating disorders in type 1 diabetes

The Mediating Role of Acceptance Action and Self-Care in Diabetes Self-Stigma's Impact on Type 2 Diabetes Quality of Life: A Cross-Sectional Study

Recently, the quality of life of individuals with diabetes has been reduced, owing to self-stigma that occurs in the process of managing the disease. This process can be improved by accepting diabetes. This study aimed to verify the dual mediating effect of acceptance action and diabetes self-care on the effect of diabetes self-stigma on the quality of life of individuals with type 2 diabetes mellitus (T2DM) in Korea. In this study, 300 of 400 data collected to develop and evaluate health equilibrium tools for individuals with T2DM were randomly selected and analyzed. Data were collected from 1 September 2020 to 31 September 2020 using a structured online questionnaire. For data analysis, descriptive statistics and Pearson's correlation analysis were performed using the Statistical Package for the Social Sciences (SPSS), version 24.0. Additionally, the dual mediation effect was analyzed using PROCESS Macro for SPSS, version 4.1. Acceptance action (B = -0.088, 95% confidence interval [CI], -0.127 to -0.054) and diabetes self-care (B = 0.046, 95% CI, 0.022-0.072) had a mediating effect on the relationship between diabetes self-stigma and quality of life in patients with T2DM in Korea. In particular, these two variables had dual mediating effects (B = 0.017, 95% CI, 0.015-0.019). This study confirmed that diabetes self-care and quality of life can be increased by improving acceptance behavior to overcome the negative impact of self-stigma on the quality of life of patients with T2DM. Establishing a strategy to increase acceptance action as part of an intervention to reduce the negative impact of self-stigma on the quality of life of patients with T2DM is necessary.

Mobile Acceptance and Commitment Therapy With Distressed First-Generation College Students: Microrandomized Trial

BACKGROUND

Extant gaps in mental health services are intensified among first-generation college students. Improving access to empirically based interventions is critical, and mobile health (mHealth) interventions are growing in support. Acceptance and commitment therapy (ACT) is an empirically supported intervention that has been applied to college students, via mobile app, and in brief intervals.

OBJECTIVE

This study evaluated the safety, feasibility, and effectiveness of an ACT-based mHealth intervention using a microrandomized trial (MRT) design.

METHODS

Participants (N=34) were 18- to 19-year-old first-generation college students reporting distress, who participated in a 6-week intervention period of twice-daily assessments and randomization to intervention. Participants logged symptoms, moods, and behaviors on the mobile app Lorevimo. After the assessment, participants were randomized to an ACT-based intervention or no intervention. Analyses examined proximal change after randomization using a weighted and centered least squares approach. Outcomes included values-based and avoidance behavior, as well as depressive symptoms and perceived stress.

RESULTS

The findings indicated the intervention was safe and feasible. The intervention increased values-based behavior but did not decrease avoidance behavior. The intervention reduced depressive symptoms but not perceived stress.

CONCLUSIONS

An MRT of an mHealth ACT-based intervention among distressed first-generation college students suggests that a larger MRT is warranted. Future investigations may tailor interventions to contexts where intervention is most impactful.

Associations of disordered eating with the intestinal microbiota and short-chain fatty acids among young adults with type 1 diabetes

BACKGROUND AND AIMS

Disordered eating (DE) in type 1 diabetes (T1D) includes insulin restriction for weight loss with serious complications. Gut microbiota-derived short chain fatty acids (SCFA) may benefit host metabolism but are reduced in T1D. We evaluated the hypothesis that DE and insulin restriction were associated with reduced SCFA-producing gut microbes, SCFA, and intestinal microbial diversity in adults with T1D.

METHODS AND RESULTS

We collected stool samples at four timepoints in a hypothesis-generating gut microbiome pilot study ancillary to a weight management pilot in young adults with T1D. 16S ribosomal RNA gene sequencing measured the normalized abundance of SCFA-producing intestinal microbes. Gas-chromatography mass-spectrometry measured SCFA (total, acetate, butyrate, and propionate). The Diabetes Eating Problem Survey-Revised (DEPS-R) assessed DE and insulin restriction. Covariate-adjusted and Bonferroni-corrected generalized estimating equations modeled the associations. COVID-19 interrupted data collection, so models were repeated restricted to pre-COVID-19 data. Data were available for 45 participants at 109 visits, which included 42 participants at 65 visits pre-COVID-19. Participants reported restricting insulin "At least sometimes" at 53.3% of visits. Pre-COVID-19, each 5-point DEPS-R increase was associated with a -0.34 (95% CI -0.56, -0.13, p = 0.07) lower normalized abundance of genus Anaerostipes; and the normalized abundance of Lachnospira genus was -0.94 (95% CI -1.5, -0.42), p = 0.02 lower when insulin restriction was reported "At least sometimes" compared to "Rarely or Never".

CONCLUSION

DE and insulin restriction were associated with a reduced abundance of SCFA-producing gut microbes pre-COVID-19. Additional studies are needed to confirm these associations to inform microbiota-based therapies in T1D.

Brief assessment of diabetes-specific psychological flexibility in racially and income diverse youth with type 1 diabetes

OBJECTIVE

Diabetes-specific psychological flexibility (the ability to engage in valued behaviors, be open to internal experiences, with present-moment awareness, while living with diabetes) is associated with HbA1c and health-related quality of life in youth with type 1 diabetes (T1D). Having brief diabetes-specific psychological flexibility assessments that perform equivalently across diverse individuals is important for research and clinical work addressing health disparities. The present study aimed to create 9-and 3-item short forms (DAASito-9 and -3) of the Diabetes Acceptance and Action Scale (DAAS-22), and evaluate their validity, reliability, and measurement invariance (MI).

RESEARCH DESIGN AND METHODS

Youth with T1D (n = 179, M_age  = 14.64, 50% female, 56% Black/African American) completed self-report measures at an endocrinology clinic visit. HbA1c was extracted from medical records. One-half of the sample was used to develop the DAASitos with the highest reliability, McDonald's 𝜔 ≥ 0.75, and convergent validity (r ≥ 0.90 to DASS-22). Confirmatory factor analyses evaluated structural validity. MI was assessed across demographic (race, gender, grade, household income) and disease characteristic (illness duration, HbA1c) groups. Correlations with measures of psychological flexibility assessed additional convergent validity, and latent mean differences across groups were evaluated after confirming MI.

RESULTS

MI was supported. The DAASito-9 and -3 were correlated in expected directions with other psychological flexibility measures, HbA1c, and health-related quality of life.

CONCLUSIONS

The psychometric properties of the DAASito-9 and -3 support their use in research and clinical care of diverse youth with T1D. Significant differences in psychological flexibility across race, income, and glycemic health warrant further research and clinical intervention.

Eating disorders early app use mediates treatment effect on clinical improvement

OBJECTIVE

Eating disorders (EDs) contribute considerably to the global burden of disease. However, most affected individuals do not receive treatment. Mobile apps present an enormous opportunity to increase access to mental healthcare services. This study examined whether the degree of usage of a self-help app for EDs mediated the app's effects on the clinical response by individuals with EDs.

METHOD

App usage measures included the total number of cognitive-behavioral meal logs, total number of days spent using the app, and the last day the app was used during the study period. Mediation analysis was performed using the MacArthur framework.

RESULTS

All usage variables met the analytic requirements for testing mediation (group means (sd) for app and standard app, respectively: logs = 74 (108) vs. 51.4 (88.1), days spent = 14.3 (17.5) vs. 10.6 (15.0), p-values from Wilcox rank sum tests p < .01). Regression coefficients indicated mediation effects. The mediation effects demonstrated support that increased engagement (as measured by logs and time spent on the app) was related to an increased likelihood of achieving a significant clinical change by the end of the trial.

DISCUSSION

Greater and longer engagement in an ED app mediates its efficacy in terms of ED remission.
