Exploring self-management characteristics in youths with type 1 diabetes mellitus: does membership in a glycemic control category matter?

Motivational Stage at Continuous Glucose Monitoring (CGM) Initiation in Pediatric Type 1 Diabetes Is Associated With Current Glycemic Control but Does Not Predict Future CGM Adherence or Glycemic Control

OBJECTIVES

The Timing of Initiation of Continuous Glucose Monitoring in Established Pediatric Diabetes (CGM TIME) Trial is a multicenter, randomized controlled trial in children with type 1 diabetes, comparing simultaneous pump and CGM with CGM initiation 6 months later (Paradigm, Veo, Enlite Sensor, Medtronic Canada). This study addresses the ability of SOCRATES (Stages Of Change Readiness And Treatment Eagerness Scale) to classify children and parents into distinct motivational stages and identify the stages' association with glycated hemoglobin (A1C) at trial entry and outcomes 6 months after CGM initiation.

METHODS

Ninety-eight of 99 eligible children 10 to 18 years of age and 137 of 141 eligible parents completed SOCRATES at trial entry and 6 months later. Parent-child agreement for motivational stage was determined by weighted kappa. Linear regression was used to examine association between motivational stage and i) A1C at trial entry and ii) change in A1C and CGM adherence 6 months after CGM initiation.

RESULTS

More than 87% of children and 88% of parents were classified into distinct motivational stages, with weak parent-child agreement. At trial entry, motivational stage was associated with A1C, which was 1.02% higher for children in the Action stage than in the Precontemplation stage (p<0.0001). When compared with children of parents in Precontemplation, A1C for children of parents in the Maintenance and Action stages were 0.83% (p=0.02) and 0.36% (p=0.048) higher, respectively. Precontemplation was associated with shorter diabetes duration. Motivational stage at CGM initiation did not predict change in A1C or CGM adherence 6 months later.

CONCLUSIONS

SOCRATES can categorize children with type 1 diabetes and their parents into motivational stages. Although motivational stage was associated with glycemic control at trial entry, it did not predict future diabetes-related behaviour or A1C.

Young Adults With Type 1 Diabetes Preparing to Transition to Adult Care: Psychosocial Functioning and Associations With Self-Management and Health Outcomes

BACKGROUND | Young adulthood is a vulnerable developmental period associated with increased risk for suboptimal health outcomes in youth with type 1 diabetes. Psychosocial factors have been associated with self-management and glycemic control in younger populations, but the extent to which these associations exist among young adults is poorly understood. This study aimed to examine the psychosocial functioning of young adults with type 1 diabetes and associated clinical outcomes. METHODS | Participants included young adults (n = 44) between the ages of 18 and 23 years in a pediatric setting who were preparing to transition to adult care. All participants completed self-report measures of psychosocial functioning at baseline as part of this longitudinal observational study. Outcome data included glycemic control, frequency of blood glucose monitoring, and self-management ratings at baseline and 1-year follow-up. RESULTS | Young adults with type 1 diabetes reported higher levels of depressive symptoms, lower self-efficacy, and more risk behaviors compared with previously published scores for adolescents. Young adults also reported greater resilience and transition readiness than their younger counterparts. Psychosocial variables were differentially related to glycemic control and frequency of blood glucose monitoring both cross-sectionally and longitudinally. CONCLUSION | This study provides key information about the psychosocial functioning of young adults with type 1 diabetes. It identifies relevant psychosocial factors that are associated with meaningful health outcomes during the transition preparation period. These findings may inform the development of clinical programs aimed at promoting transition preparation and health outcomes in young adults with type 1 diabetes.

Measuring Self-Efficacy in the Context of Pediatric Diabetes Management: Psychometric Properties of the Self-Efficacy for Diabetes Scale

Objective

The Self-Efficacy for Diabetes Scale (SED) is a widely used measure of diabetes-specific self-efficacy with three subscales: diabetes-specific self-efficacy (SED-D), medical self-efficacy (SED-M), and general self-efficacy (SED-G). The present study examined the factor structure and construct validity of the SED in 116 youth, aged 10-16 years (13.60 ± 1.87), with type 1 diabetes mellitus.

Methods

Confirmatory factor analysis (CFA) was used to examine the factor structure of the SED. Correlational and regression analyses examined relations between subscales and select outcomes.

Results

CFA of the original three-factor structure provided a poor fit to the data. Factor models using rescaled items were tested. Results provided preliminary evidence for the SED-D as an independent one-factor model, and for a reduced one-factor model. Significant associations were found between the SED subscales, responsibility for diabetes management, and glycated hemoglobin.

Conclusions

Results provide limited support for the SED-D as a reliable and valid measure of diabetes-specific self-efficacy.

An integrative review of self-efficacy measurement instruments in youth with type 1 diabetes

PURPOSE

The purpose of this study is to assess the extant literature on instruments used to measure self-efficacy in youth with type 1 diabetes (T1DM) and their caregivers and to critically evaluate these measurements.

METHODS

An integrative review (2003-2013) was conducted searching PsycINFO, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and US National Library of Medicine PubMed service (PubMed) databases using key words diabetes, type 1 diabetes, and self-efficacy. The authors reviewed the resulting 294 references for inclusion criteria of (a) sample of youth with T1DM or sample of caregivers of youth with T1DM, (b) description of the self-efficacy instrument as primary research, and (c) the instrument measured self-efficacy specifically related to diabetes management. Forty-five articles out of the initial 294 met criteria.

RESULTS

Of the 45 articles, 10 different self-efficacy instruments were identified. The primary theoretical framework used was Bandura's social cognitive theory and model of self-efficacy. Most participants were white middle-class T1DM youth. Evaluations to assess validity often were not reported; however, a majority of studies reported high internal consistency of the instruments.

CONCLUSIONS

Sample homogeneity could limit the applicability of results to certain patient populations. Further psychometric analysis, including validity assessments, should be conducted in more diverse samples. Development of valid and reliable instruments for measuring self-efficacy that are sensitive to change across a wider caregiver base over time is necessary. While this review examined reliable and valid instruments used in research, future opportunities include evaluation of measuring self-efficacy in T1DM youth exposed to recent advances in diabetes management technologies.

Identification and prediction of group-based glycemic control trajectories during the transition to adolescence

OBJECTIVE

To identify trajectories of glycemic control over a period of 3 years in a pediatric sample of youth diagnosed with Type 1 diabetes transitioning to adolescence. A second aim was to examine a set of modifiable individual and family level baseline predictors of glycemic control group membership.

METHODS

This multisite, prospective study included 239 children and adolescents (ages 9-11 years at baseline) diagnosed with Type 1 diabetes and their caregivers. Glycemic control was based on hemoglobin A1c (HbA1c) collected at 6-month intervals over a period of 3 years. Predictors of glycemic control membership included baseline global executive functioning, diabetes self-management, diabetes-specific family conflict, blood glucose monitoring frequency, and relevant individual and family level covariates.

RESULTS

Group-based trajectory analyses were used to describe patterns of glycemic control from baseline to 36 months and 3 trajectories were identified: low risk (42.9%), elevated risk (44.6%), and high risk (12.1%) subgroups. Baseline maternal-reported family conflict, blood glucose monitoring frequency, and gender were significant predictors of glycemic control group membership. Higher levels of baseline family conflict, lower frequency of blood glucose monitoring, and female gender were associated with elevated and high-risk group membership.

CONCLUSIONS

These findings underscore the importance of examining trajectories of HbA1c across time. These results suggest that problematic trajectories of glycemic control are evident during the transition to adolescence. Furthermore, there are modifiable individual and family level characteristics that predict group membership and hence could be targeted in interventions to ensure adequate glycemic control is maintained over time and that risks for diabetes-related complications are reduced.

Patterns of self-management in pediatric type 1 diabetes predict level of glycemic control 2 years later

OBJECTIVE

To determine if 3 distinct self-management patterns (i.e., maladaptive, moderate/mixed, and adaptive) observed at baseline, 1 year, and 2 years in a sample of youth with type 1 diabetes and their caregivers predicted mean differences in adolescent's subsequent glycemic control.

METHODS

This study is a descriptive, multisite, prospective study that examined a sample of youth diagnosed with type 1 diabetes (ages 9-11 years at baseline). Youth and their maternal and paternal caregivers provided information about the youth's self-management patterns at baseline, 1 year, and 2 years using the Diabetes Self-Management Profile structured interview. Glycemic control (hemoglobin A1c: HbA1c) was examined at baseline and 6, 12, 18, and 24 months.

RESULTS

Three distinct self-management patterns were observed at 1 year and 2 years, which were conceptually consistent with previously reported baseline self-management patterns. Youth identified by their maternal caregivers as having adaptive self-management patterns at baseline had better glycemic control across 2 years compared with those in the maladaptive and mixed self-management groups. Similarly, maternal reports suggested that youth with less adaptive self-management patterns generally had worse glycemic control over time and HbA1c values above the American Diabetes Association recommendations. Youth and paternal caregiver reports yielded more variable findings.

CONCLUSIONS

Findings underscore the stability of self-management patterns in pediatric type 1 diabetes and the need for preventive interventions that are tailored to specific patterns of self-management associated with risk for problematic glycemic control.

Common sense model of illness in youth with type 1 diabetes or sickle cell disease

OBJECTIVES

To qualitatively explore differences in Leventhal's common sense model (CSM) constructs between youth with type 1 diabetes (T1D) and sickle cell disease (SCD) and between different age groups and level of disease control.

METHODS

Two structured individual interviews were conducted in 24 youth with T1D (n=12) or SCD (n=12). Patients were between 8 and 21 years of age, had either good or poor disease control, and were seen at an outpatient children's hospital medical clinic.

RESULTS

YOUTH CONCEPTUALIZE THEIR CHRONIC DISEASE IN TERMS OF IDENTITY, CAUSE, TIMELINE, CONTROL, AND CONSEQUENCES: both cognitive and emotional dimensions are apparent. There was considerable contrast between discussions of youth with well- and poorly controlled T1D but little contrast between youth with well- and poorly controlled SCD. Surprisingly, youth with well-controlled T1D mentioned emotions most frequently. No youth with poorly controlled T1D described disease acceptance, but the majority of youth with well-controlled T1D did. Adolescents and young adults with good T1D control appear to understand disease cause, have better illness coherence, and habitually link discussion of symptoms and negative emotions with solutions. Youth with poorly controlled T1D appeared more likely to connect symptoms with negative consequences. Consequences included 1) disease symptoms, 2) the need to perform self-care activities, 3) physical outcomes, 4) health-system activities, 5) emotions, and 6) life impact. Interestingly, sickling crisis was mentioned more frequently by youth with good SCD control than by those with poor SCD control. Youth with SCD are distressed by others' judgmental perceptions and by feeling different from others.

CONCLUSIONS

In contrast to previous CSM work, youth with well-controlled T1D in this study discussed emotions more frequently than did those with poor control. Disease perceptions were similar between youth with well- and poorly controlled SCD. Results indicate there are noteworthy cognitive and emotional differences between youth with different types of disease and levels of disease control.

Use of the Family Interaction Macro-coding System with families of adolescents: psychometric properties among pediatric and healthy populations

OBJECTIVE

To examine reliability and validity data for the Family Interaction Macro-coding System (FIMS) with adolescents with spina bifida (SB), adolescents with type 1 diabetes mellitus (T1DM), and healthy adolescents and their families.

METHODS

Sixty-eight families of children with SB, 58 families of adolescents with T1DM, and 68 families in a healthy comparison group completed family interaction tasks and self-report questionnaires. Trained coders rated family interactions using the FIMS.

RESULTS

Acceptable interrater and scale reliabilities were obtained for FIMS items and subscales. Observed FIMS parental acceptance, parental behavioral control, parental psychological control, family cohesion, and family conflict scores demonstrated convergent validity with conceptually similar self-report measures.

CONCLUSIONS

Preliminary evidence supports the use of the FIMS with families of youths with SB and T1DM and healthy youths. Future research on overall family functioning may be enhanced by use of the FIMS.
