Development of a Typology of Diabetes-Specific Family Functioning Among Adults With Type 2

Glycemic outcomes of a family-focused intervention for adults with type 2 diabetes: Main, mediated, and subgroup effects from the FAMS 2.0 RCT

AIMS

Family/friend Activation to Motivate Self-care (FAMS) is a self-care support intervention delivered via mobile phones. We evaluated FAMS' effects on hemoglobin A1c (HbA1c) and intervention targets among adults with type 2 diabetes in a 15-month RCT.

METHODS

Persons with diabetes (PWDs) were randomized to FAMS or control with their support person (family/friend, optional). FAMS included monthly phone coaching and text messages for PWDs, and text messages for support persons over a 9-month intervention period.

RESULTS

PWDs (N = 329) were 52 % male, 39 % reported minoritized race or ethnicity, with mean HbA1c 8.6 ± 1.7 %. FAMS improved HbA1c among PWDs with a non-cohabitating support person (-0.64 %; 95 % CI [-1.22 %, -0.05 %]), but overall mean effects were not significant. FAMS improved intervention targets including self-efficacy, dietary behavior, and family/friend involvement during the intervention period; these improvements mediated post-intervention HbA1c improvements (total indirect effect -0.27 %; 95 % CI [-0.49 %, -0.09 %]) and sustained HbA1c improvements at 12 months (total indirect effect -0.19 %; 95 % CI [-0.40 %, -0.01 %]).

CONCLUSIONS

Despite improvements in most intervention targets, HbA1c improved only among PWDs engaging non-cohabitating support persons suggesting future family interventions should emphasize inclusion of these relationships. Future work should also seek to identify intervention targets that mediate improvements in HbA1c.

Family Typology for Adults With Type 2 Diabetes: Longitudinal Stability and Validity for Diabetes Management and Well-being

OBJECTIVE

We validated longitudinally a typology of diabetes-specific family functioning (named Collaborative and Helpful, Satisfied with Low Involvement, Want More Involvement, and Critically Involved) in adults with type 2 diabetes.

RESEARCH DESIGN AND METHODS

We conducted k-means cluster analyses with nine dimensions to determine if the typology replicated in a diverse sample and if type assignment was robust to variations in sampling and included dimensions. In a subsample with repeated assessments over 9 months, we examined the stability and validity of the typology. We also applied a multinomial logistic regression approach to make the typology usable at the individual level, like a diagnostic tool.

RESULTS

Participants (N = 717) were 51% male, more than one-third reported minority race or ethnicity, mean age was 57 years, and mean hemoglobin A1c (HbA1c) was 7.9% (63 mmol/mol; 8.7% [72 mmol/mol] for the longitudinal subsample). The typology was replicated with respect to the number of types and dimension patterns. Type assignment was robust to sampling variations (97% consistent across simulations). Type had an average 52% stability over time within participants; instability was not explained by measurement error. Over 9 months, type was independently associated with HbA1c, diabetes self-efficacy, diabetes medication adherence, diabetes distress, and depressive symptoms (all P < 0.05).

CONCLUSIONS

The typology of diabetes-specific family functioning was replicated, and longitudinal analyses suggest type is more of a dynamic state than a stable trait. However, type varies with diabetes self-management and well-being over time as a consistent independent indicator of outcomes. The typology is ready to be applied to further precision medicine approaches to behavioral and psychosocial diabetes research and care.

Well-being outcomes of a family-focused intervention for persons with type 2 diabetes and support persons: Main, mediated, and subgroup effects from the FAMS 2.0 RCT

AIMS

Type 2 diabetes self-management occurs within social contexts. We sought to test the effects of Family/friend Activation to Motivate Self-care (FAMS), a self-care support intervention delivered via mobile phones, on psychosocial outcomes for persons with diabetes (PWDs) and their support persons.

METHODS

PWDs had the option to enroll with a friend/family member as a support person in a 15-month RCT to evaluate FAMS versus enhanced usual care. FAMS included 9 months of monthly phone coaching and text message support for PWDs, and text message support for enrolled support persons.

RESULTS

PWDs (N = 329) were 52% male and 39% reported minoritized race or ethnicity ; 50% enrolled with elevated diabetes distress. Support persons (N = 294) were 26% male and 33% reported minoritized race or ethnicity. FAMS improved PWDs' diabetes distress (d = -0.19) and global well-being (d = 0.21) during the intervention, with patterns of larger effects among minoritized groups. Post-intervention (9-month) and sustained (15-month) improvements were driven by changes in PWDs' self-efficacy, self-care behaviors, and autonomy support. Among support persons, FAMS improved helpful involvement without increasing burden or harmful involvement.

CONCLUSIONS

FAMS improved PWDs' psychosocial well-being, with post-intervention and sustained improvements driven by improved self-efficacy, self-care, and autonomy support. Support persons increased helpful involvement without adverse effects.

Glycemic outcomes of a family-focused intervention for adults with type 2 diabetes: Main, mediated, and subgroup effects from the FAMS 2.0 RCT

Aims

Family/friends Activation to Motivate Self-care (FAMS) is a self-care support intervention delivered via mobile phones. We evaluated FAMS effects on hemoglobin A1c (HbA1c) and intervention targets among adults with type 2 diabetes in a 15-month RCT.

Methods

Persons with diabetes (PWDs) and their support persons (family/friend, optional) were randomized to FAMS or control. FAMS included monthly phone coaching and text messages for PWDs, and text messages for support persons over a 9-month intervention period.

Results

PWDs (N=329) were 52% male, 39% from minoritized racial or ethnic groups, with mean HbA1c 8.6±1.7%. FAMS improved HbA1c among PWDs with a non-cohabitating support person (-0.64%; 95% CI [-1.22%, -0.05%]), but overall effects were not significant. FAMS improved intervention targets including self-efficacy, dietary behavior, and family/friend involvement during the intervention period; these improvements mediated post-intervention HbA1c improvements (total indirect effect -0.27%; 95% CI [-0.49%, -0.09%]) and sustained HbA1c improvements at 12 months (total indirect effect -0.19%; 95% CI [-0.40%, -0.01%]).

Conclusions

Despite improvements in most intervention targets, HbA1c improved only among PWDs engaging non-cohabitating support persons suggesting future family interventions should emphasize inclusion of these relationships. Future work should also seek to identify intervention targets that mediate improvements in HbA1c.

Optimizing adaptive stepped-care interventions to change adults' health behaviors: A systematic review

Chronic diseases are ubiquitous and costly in American populations. Interventions targeting health behavior change to manage chronic diseases are needed, but previous efforts have fallen short of producing meaningful change on average. Adaptive stepped-care interventions, that tailor treatment based on the needs of the individual over time, are a promising new area in health behavior change. We therefore conducted a systematic review of tests of adaptive stepped-care interventions targeting health behavior changes for adults with chronic diseases. We identified 9 completed studies and 13 research protocols testing adaptive stepped-care interventions for health behavior change. The most common health behaviors targeted were substance use, weight management, and smoking cessation. All identified studies test intermediary tailoring for treatment non-responders via sequential multiple assignment randomized trials (SMARTs) or singly randomized trials (SRTs); none test baseline tailoring. From completed studies, there were few differences between embedded adaptive interventions and minimal differences between those classified as treatment responders and non-responders. In conclusion, updates to this work will be needed as protocols identified here publish results. Future research could explore baseline tailoring variables, apply methods to additional health behaviors and target populations, test tapering interventions for treatment responders, and consider adults' context when adapting interventions.

Exploring typologies of appraisals, involvement, and distress in type 2 diabetes family members

The present study conducted a latent profile analysis from a US national sample of 446 family members to identify and predict unique clusters of family members' PWD illness appraisals, involvement, and psychological distress. Time since diagnosis, diabetes adherence, the relationship with the PWD, age, gender, race/ethnicity, income, and economic pressure were included as predictors. Class membership was used to predict the family members' own health behaviors (sleep quality, days of physical activity, and diet quality). Results revealed four distinct classes: Moderately Concerned, Involved, and Distressed (32.51%), Least Concerned, Distressed, and Involved (27.13%), Less Concerned and Distressed, Moderately Involved (23.77%), and Most Concerned, Involved, and Distressed (16.82%). The significant predictors and outcomes of class membership revealed interesting patterns in associations with class membership. Consequently, in addition to involving family members, health promotion and intervention efforts must consider the psychological health and illness appraisals of family members rather than a one-size-fits-all approach.

Diabetes Mellitus Family Assessment Instruments: A Systematic Review of Measurement Properties

Although many instruments are used to assess the families of people with diabetes, their measurement properties have not been systematically reviewed. We aimed to identify and evaluate the psychometric properties of the instruments used to assess family functioning in adults with diabetes.

METHODS

A systematic literature review, according to the JBI systematic reviews of measurement properties, was conducted using different databases, including gray literature. PROSPERO registration number: CRD42021239733. Two independent reviewers searched, screened, and assessed the risk of bias among the articles according to the COSMIN methodology. The quality of each included instrument was assessed using the updated criteria for good measurement properties.

RESULTS

Eighty-one studies were included, and thirty-one eligible instruments were identified. The psychometric properties frequently assessed were structural validity, internal consistency, and construct validity.

CONCLUSIONS

Although 31 instruments were included, none of their psychometric properties were scored as "very good". From the instruments scored as adequate on development and content validity, five stood out for their quality appraisal.. The development of new instruments is not recommended. More studies should be conducted on the existing instruments to assess the less commonly evaluated psychometric properties. Using valid instruments to develop and evaluate interventions is essential to promote health literacy and the effectiveness of diabetes management.

Persons with Diabetes' Perceptions of Family Burden and Associated Factors

BACKGROUND

Families of a person with diabetes play a vital part in diabetes management since their support helps with regimen engagement in self-management behaviors. However, focal information on the family burden of diabetes is lacking. This study is aimed at, therefore, assessing the persons with diabetes' perceptions of family burden and associated factors at a university hospital.

METHODS AND MATERIALS

A facility-based cross-sectional study design was conducted from July 26 to September 26, 2021on 403 persons' with diabetes attending Jimma Medical Center diabetic clinic, the study sample was selected using a simple random sampling method. The data was collected using the Zarit burden questionnaire through face-to-face interviews. Descriptive statistics (mean, standard deviation, frequency, and percentages) were ordered logistic regression, and statistical significance was declared at P value ≤0.05. Results and Discussion. About 36.8% of the patient was in mild to moderate family burden of diabetes. Farmer (AOR 5.419; CI: 1.18, 24.872), living with partners and family (AOR: 0.110, CI: 0.018, 0.659), comorbidity (AOR 5.419; CI: 1.18, 24.872), oral hypoglycemic agent (AOR: 0.380, CI: 0.191, 0.758), and being never hospitalized before because of diabetes (AOR: 0.044, CI: 0.003, 0.571) was statistically associated with a family burden.

CONCLUSION

About one-fourth of diabetic patient-perceived mild to the moderate family burden of diabetes, persons with diabetes who work as farmers and have comorbidities have a higher opinion of family burden, whereas those who live with partners or family members, use oral hypoglycemic medications, and have never been hospitalized for diabetes have a lower view of family burden due to diabetes. The results of this study suggest that strategies for health promotion, intervention, and prevention of diabetes at the family level should consider the interaction between family member burden and the patient's sociodemographic and disease-related factors. A further large-scale study is required to validate these findings.

Rationale, design, and recruitment outcomes for the Family/Friend Activation to Motivate Self-care (FAMS) 2.0 randomized controlled trial among adults with type 2 diabetes and their support persons

BACKGROUND

Self-care behaviors help reduce hemoglobin A1c (HbA1c) and prevent or delay type 2 diabetes (T2D) complications. Individualized interventions that support goal setting and self-monitoring improve self-care and HbA1c in the short-term; engaging family and friends may enhance and/or sustain effects. Family/Friend Activation to Motivate Self-care (FAMS) is a mobile phone-delivered intervention (i.e., phone coaching and text message support) based on Family Systems Theory which was successfully piloted among diverse adults with T2D.

METHODS

We made improvements to FAMS and conducted iterative usability testing to finalize FAMS 2.0 before evaluation in a randomized controlled trial (RCT). Adult persons with diabetes (PWDs) who enrolled were asked to invite a support person (friend or family member) to participate alongside them. For the RCT, dyads were randomly assigned to FAMS 2.0 or enhanced treatment as usual (control) for the first 9 months of the 15-month trial. Outcomes include PWDs' HbA1c and psychosocial well-being (including diabetes distress) and support persons' own diabetes distress and support burden.

RESULTS

We recruited RCT participants from April 2020 through October 2021 (N = 338 PWDs with T2D; 89% [n = 300] with a support person). PWDs were 52% male, 62% non-Hispanic White, aged 56.9 ± 11.0 years with HbA1c 8.7% ± 1.7% at enrollment; 73% cohabitated with their enrolled support person. Data collection is ongoing through January 2023.

CONCLUSION

Findings will inform the utility of engaging family/friends in self-care behaviors for both PWD and support person outcomes. Using widely available mobile phone technology, FAMS 2.0, if successful, has potential for scalability.
