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

Implementation and evaluation of a longitudinal diabetes educational programme for adolescents

INTRODUCTION

International guidelines recommend structured and continuous educational programmes to expand diabetes knowledge and self-efficacy in youth. To address these recommendations within a paediatric diabetes clinic, we conducted a three-phase quality improvement project aimed at improving adolescents' confidence in diabetes self-management skills.

METHODS

In phase 1, the Diabetes Learning Centre (DLC), an educational programme for adolescents with type 1 diabetes (T1D) ages 13-17 years, was developed and implemented. Programme feasibility was evaluated through programme attendance rates. Phase 2 aimed to guide ongoing programme development and optimisation. DLC attendees rated their baseline confidence in overall and individual T1D self-management skills on a 5-point Likert scale. Patient characteristics were summarised using descriptive statistics and the association between patient characteristics and overall confidence in T1D self-management was evaluated. Phase 3 used patient surveys to evaluate patient satisfaction and reported change in confidence in self-management skills following DLC attendance.

RESULTS

In phase 1, 232 (81%) of eligible adolescents attended the DLC during the study period. In phase 2, median overall confidence in diabetes management on a Likert scale (0-4) was 3, representing 'quite confident', although confidence was low in some essential self-management skills. Higher confidence was associated with lower HbA1c (p<0.001). In phase 3, 77 (85%) of participants reported high levels of satisfaction with the DLC. 106 (82%) of completed worksheets were associated with improved confidence in the diabetes self-management skill addressed.

CONCLUSIONS

Implementation of a longitudinal T1D educational model was feasible with good uptake in an existing T1D programme. While confidence at baseline was quite high for overall T1D self-management, it was low in some essential self-management skills, highlighting the need for this programme and specific educational gaps. Adolescents reported improvements in confidence and high levels of satisfaction following DLC attendance. Our model provides a replicable programme template to address longitudinal education needs.

Implementation of Psychosocial Screening into Diabetes Clinics: Experience from the Type 1 Diabetes Exchange Quality Improvement Network

PURPOSE OF REVIEW

Although advances in diabetes technology and pharmacology have significantly and positively impacted diabetes management and health outcomes for some, diabetes care remains burdensome and can be challenging to balance with other life priorities. The purpose of this article is to review the rationale for assessment of psychosocial domains in diabetes care settings and strategies for the implementation of psychosocial screening into routine practice. Survey data from the Type 1 Diabetes Exchange Quality Improvement Network is highlighted.

RECENT FINDINGS

Implementation of psychosocial screening requires identifying the population; selecting validated tools to assess target domains; determining frequency of screening and mode of survey delivery; and scoring, interpreting, documenting, and facilitating referrals such that these processes are part of clinical workflows. Recognizing the influence of psychosocial factors for people with diabetes (PWD), professional society guidelines for comprehensive diabetes care recommend the integration of psychosocial screening into routine care.

Oral immunotherapy for food allergy in children: is it worth it?

INTRODUCTION

Oral immunotherapy (OIT) is effective at inducing desensitization in food-allergic individuals, and is a valid therapeutic option for those allergic to peanut, cow's milk and egg. However, there is a high rate of dose-related adverse events, and at least one fatality to OIT has been reported.

AREAS COVERED

We provide an update on the broader framework of issues which will impact on the availability and uptake of OIT.

EXPERT OPINION

The need for standardized products remains controversial. A licensed product exists for peanut-OIT, but OIT can also be safely achieved using peanut-containing foods at much lower cost. For other allergens, OIT can only be done with non-pharma products - something which has been done safely for over 2 decades. There is a need to develop personalized protocols for OIT, particularly for the 20% of patients unable to tolerate standard OIT. Cost-effectiveness is dependent on improved quality of life, but evidence for this is currently lacking, and is a key evidence gap. OIT is likely to be cost-effective, particularly if noncommercial products are used. There may be a trade-off: in patients with lower reaction thresholds, a commercial product may be needed for initial updosing, until a level of desensitization is achieved when they can be switched to natural food products.

Self-administration of adrenaline for anaphylaxis during in-hospital food challenges improves health-related quality of life

OBJECTIVE

To assess the impact of anaphylaxis on health-related quality of life (HRQL) and self-efficacy in food-allergic patients undergoing in-hospital food challenge.

DESIGN

Secondary analysis of a randomised controlled trial.

SETTING

Specialist allergy centre.

PATIENTS

Peanut-allergic young people aged 8-16 years.

INTERVENTIONS

Double-blind, placebo-controlled food challenge to peanut, with HRQL and self-efficacy assessed using validated questionnaire, approximately 2 weeks prior to and 2 weeks after challenge. Where possible, anaphylaxis was treated with self-injected adrenaline (epinephrine).

MAIN OUTCOME MEASURES

Change in HRQL and self-efficacy.

RESULTS

56 participants had reactions at food challenge, of whom 16 (29%) had anaphylaxis. Overall, there was an improvement in HRQL (mean 2.6 points (95% CI 0.3 to 4.8); p=0.030) and self-efficacy (mean 4.1 points (95% CI 2.4 to 5.9); p<0.0001), independent of whether anaphylaxis occurred. Parents also reported improved HRQL (mean 10.3 points (95% CI 5.9 to 14.7); p<0.0001). We found evidence of discordance between the improvement in HRQL and self-efficacy as reported by young people and that perceived by parents in their child.

CONCLUSIONS

Anaphylaxis at food challenge, followed by self-administration of injected adrenaline, was associated with an increase in HRQL and self-efficacy in young people with peanut allergy. We found no evidence that the occurrence of anaphylaxis had a detrimental effect. Young people should be encouraged to self-administer adrenaline using their autoinjector device to treat anaphylaxis at in-hospital challenge.

Social Determinants of Health, Goals and Outcomes in High-Risk Children With Type 1 Diabetes

OBJECTIVES

Despite advances in technology and type 1 diabetes (T1D) care, children from low-income families continue to have suboptimal outcomes and increased health-care utilization. In this study, we describe social determinants of health (SDOH) in high-risk children with T1D, as well as their SDOH-related priority goals, and assess the correlation between SDOH, glycemic control and health-care utilization.

METHODS

Caregivers of children aged 4 to 18 years with a diagnosis of T1D of >1 year, poor glycemic control (glycated hemoglobin [A1C] ≥9.5%) or high health-care utilization (≥2 diabetes-related hospitalizations, emergency department attendances or missed outpatient appointments in the previous year) were included. Primary caregiver health-related quality of life (HRQOL), self-efficacy (Maternal Self-Efficacy in Diabetes [MSED] scale) and SDOH were assessed. Goals were identified after assessment by a community health worker.

RESULTS

Fifty-three families were included, most (n=48, 91%) of whom had government insurance. Children had a median age of 13.4 (interquartile range [IQR], 12 to 15.3) years and a median A1C of 11.1% (IQR, 10% to 13%). Almost half of the families (n=24, 45%) reported at least 1 adverse SDOH. One or more adverse SDOH was associated with significantly lower total HRQOL scores (56.6 [IQR, 38.5 to 70.7] vs 77.8 [IQR, 60.8 to 92.4], p=0.004), but not associated with A1C (p=0.3), emergency department visits (p=0.9) or MSED (p=0.5).

CONCLUSIONS

Screening for adverse SDOH and addressing these barriers to glycemic control is not part of routine T1D care. In children with poorly controlled T1D and high health-care utilization, we have demonstrated a high prevalence of adverse SDOH, which may represent a modifiable factor to improve outcomes in this patient population.

Testing Usability and Feasibility of a Mobile Educator Tool for Pediatric Diabetes Self-Management: Mixed Methods Pilot Study

BACKGROUND

Mobile interventions hold promise as an intervention modality to engage children in improving diabetes self-management education, attitudes, and behaviors.

OBJECTIVE

This pilot study aimed to explore the usability, acceptability, and feasibility of delivering a mobile diabetes educational tool to parent-child pairs in a clinical setting.

METHODS

This mixed methods pilot study comprised two concurrent phases with differing study participants. Phase 1 used user testing interviews to collect qualitative data on the usability and acceptability of the tool. Phase 2 used a single-arm pre- and poststudy design to quantitatively evaluate the feasibility and preliminary efficacy of the intervention. Study participants (English-speaking families with youth aged 5-14 years with insulin-dependent diabetes) were recruited from an urban hospital in Massachusetts, United States. In phase 1, parent-child pairs were invited to complete the intervention together and participate in 90-min user testing interviews assessing the tool's usability and acceptability. Interview transcripts were analyzed using a directed content analysis approach. In phase 2, parent-child pairs were invited to complete the intervention together in the clinical setting. Measures included parental and child knowledge, attitudes, and behaviors related to diabetes management (self-report surveys) and child hemoglobin A1c levels (medical record extractions); data were collected at baseline and 1-month follow-up. Pre- and postoutcomes were compared using paired t tests and the Fisher exact test.

RESULTS

A total of 11 parent-child pairs (N=22) participated in phase 1 of the study, and 10 parent-child pairs (N=20) participated in phase 2 of the study. Participants viewed the mobile educational tool as acceptable (high engagement and satisfaction with the layout, activities, and videos) and identified the areas of improvement for tool usability (duration, directions, and animation).

CONCLUSIONS

The findings from this pilot study suggest that the mobile educational tool is an informative, engaging, and feasible way to deliver diabetes self-management education to parents and children in an urban hospital setting. Data will inform future iterations of this mobile diabetes educational intervention to improve usability and test intervention efficacy.

[Validation of the German Version of Pediatric Self-Efficacy for Diabetes-Type-1 Scale]

INTRODUCTION

Since there is no suitable tool for measuring the specific, diabetes-related self-efficacy in children with type-1-diabetes in German language, this paper presents the construction and validation of Pediatric Self-Efficacy for Diabetes-Type-1 Scale (PSEDT-1). The intention was to develop a guideline-compliant, pediatric, revised self-efficacy scale on the basis of Grossman, Brink and Hauser̓s SED.

DESIGN

Children with type 1 diabetes (N=221) were included in a clinical, multi-centre validation study. To assess sensitivity to change, 85 of these children were asked to complete the PSEDT-1 before, immediately after, and 6 months after inpatient diabetes training. PSEDT-1 has been associated with scales that measure constructs that are similar and different in terms of content. The interpretation of the correlation results should provide information on validity. The PSEDT-1 was thus reviewed using the German Multidimensional Self-Assessment Scale (MSWS), the German questionnaire on health and illness-related control beliefs (KKG).

RESULTS

The reliability results showed a good internal consistency with Cronbach's α=0,87; the discriminatory power of the items was acceptable. Exploratory factor analysis identified 4 factors that account for 54% of the variance: 1) diabetes self-management skill, 2) (medical) insulin management competence, 3) (general) self-assertiveness, 4) autonomous self-regulation. The construct validity of PSEDT-1 has been evaluated by estimating its association with other variables. It was possible to verify the theoretically expected correlation patterns. In addition, the study results showed indications of sufficiently high sensitivity to change.

DISCUSSION

The results suggest that PSEDT-1 is a valid and reliable tool that, in addition to the scale values of the competence areas of diabetes self-management, medical management, and general self-assertion, also determines the scale value of autonomous self-regulation to assess diabetes-related self-efficacy.

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.

Validation of a diabetes knowledge test for Indian children, adolescents and young adults with type 1 diabetes mellitus

INTRODUCTION

Diabetes knowledge has a large impact on glycemic control. There is a pressing need for creation of validated tests of knowledge for different ethnic groups.

OBJECTIVE

To create and validate a diabetes knowledge test (DKT) for young Indians with type 1 diabetes mellitus (T1DM).

METHODS

We created a 34 item Hindi language DKT, with basic (19-questions) and advanced (15-questions) components. It was administered to 77 consecutive patients who had previously received in-hospital diabetes education. We hypothesized that the test scores would be higher for patients residing in urban regions, for patients with higher maternal education, and those with lower HbA1c. Cronbach's alpha (α) was used to calculate the test reliability.

RESULTS

The DKT score was significantly higher in families with higher (>class 12th) maternal formal education compared with lower [70.0 (95% C.I. 67.2-73.5) vs 54.2 (95% C.I. 44.0-57.3), p<0.001] and urban residence compared with rural [68.5 (95% C.I. 63.4-70.6) vs 54.5 (95% C.I. 42.5-61.7), p<0.001]. It had negative correlation with HbA1c (r=-0.268, p=0.019). The Cronbach's α was 0.87 for the entire test, and for the basic and advanced components was 0.78 and 0.74 respectively.

CONCLUSION

The DKT India is a valid and reliable instrument to evaluate diabetes knowledge in Hindi speaking Indian children, adolescents and young adults with T1DM.

Psychometric properties of the Escala de Autoeficacia para la Depresión en Adolescentes (EADA) among Latino youth with type 1 diabetes

Type 1 Diabetes (T1D) adolescents have higher depression rates than controls. Self-efficacy has been proposed as a mediator of therapeutic changes. Few scales assess emotional self-efficacy in adolescents. None have been validated with T1D youth. We examined the psychometric properties of the Escala de Autoeficacia para la Depresión en Adolescentes (EADA) with 51 T1D youth (aged 12-17 years), enrolled in a depression treatment study. Adolescents and one parent each completed several measures. Youth completed the EADA. We used alpha coefficient to estimate its internal consistency and Pearson correlation to assess its concurrent and construct validity. We found an internal consistency of 0.93 for the EADA total score, with alpha values ranging from 0.71 to 0.85 for its subscales. EADA scores significantly (p ≤ 0.05) diverged from self-reports of depression, hopelessness/helplessness, suicidal ideation, self-esteem/guilt problems, depression-related cognitive alterations, hypoglycemic symptoms, and problems in quality of life. Its scores converged with youth's life satisfaction, self-efficacy for diabetes, self-care behaviors, and perceptions about the quality of group therapy climate and family social support. Our findings document EADA's reliability and validity when used with T1D youth and extend the supporting evidence on its psychometric properties to a clinical sample of Latino adolescents.

Questionnaire on adaptation to type 1 diabetes among children and its relationship to psychological disorders

Objective:

to study the psychometric properties of an adaptive disease response questionnaire for use with Spanish children with type 1 diabetes; to analyse this response in this sample and to observe the relationship between adaptive response and levels of anxiety-depression.

Method:

a total of 100 patients with type 1 diabetes aged between nine and 16 years (M=12.28, SD=1.78) participated in the study, of which 59% were children. Data was collected in public hospitals via interviews using the Adaptive Disease Response Questionnaire and Anxiety and Depression Scale. The data was analysed using Pearson correlations, multiple hierarchical linear regressions, Student’s t Test for independent samples, and Cohen’s d effect size to determine reliability and validity.

Result:

the instrument was shown to have adequate psychometric properties. Adaptive response was generally high. Adaptive response is negatively related to emotional distress, being a better predictor of depression than of anxiety. There was no association betwee adaptation and sex and age.

Conclusion:

promoting a better adaptive response appears to reduce emotional distress, especially in the case of depression, regardless of the age or gender of the patients.

Health Care Transition for Young Adults With Type 1 Diabetes: Stakeholder Engagement for Defining Optimal Outcomes

Objectives

Research on the transition to adult care for young adults with type 1 diabetes (T1D) emphasizes transition readiness, with less emphasis on transition outcomes. The relatively few studies that focus on outcomes use a wide variety of measures with little reliance on stakeholder engagement for measure selection.

Methods

This study engaged multiple stakeholders (i.e., young adults with T1D, parents, pediatric and adult health care providers, and experts) in qualitative interviews to identify the content domain for developing a multidimensional measure of health care transition (HCT) outcomes.

Results

The following constructs were identified for a planned measure of HCT outcomes: biomedical markers of T1D control; T1D knowledge/skills; navigation of a new health care system; integration of T1D into emerging adult roles; balance of parental involvement with autonomy; and "ownership" of T1D self-management.

Discussion

The results can guide creation of an initial item pool for a multidimensional profile of HCT outcomes.

Evaluating Parents' Self-Efficacy for Diabetes Management in Pediatric Type 1 Diabetes

Objective

To examine the factor structure and construct validity of the Maternal Self-Efficacy for Diabetes Management Scale (MSED) in 135 youth ( Mage  = 13.50  ±  1.83 years), with type 1 diabetes mellitus.

Method

The study used exploratory factor analysis (EFA) to examine the factor structure and correlations to examine relationships among MSED factors and select parent and child diabetes-related health behaviors and outcomes.

Results

EFA identified an 11-item three-factor solution (χ 2 (25, n  = 133)  = 40.22, p  < .03, RMSEA = 0.07, CFI = 0.98, TLI = 0.97), with factors corresponding to parents' perceived ability to manage their child's diabetes (MSED-M), problem-solve issues surrounding glycemic control (MSED-P), and teach their child about diabetes care (MSED-T). Correlational analyses revealed significant associations between the MSED-M and MSED-T and parent-reported optimism and youth's diabetes-specific self-efficacy. The MSED-T was also associated with glycated hemoglobin and self-monitoring blood glucose.

Conclusions

Results provide preliminary evidence for the reliability and validity of a three-factor solution of the MSED.

Diabetes conflict outstrips the positive impact of self-efficacy on youth adherence and glycemic control in type 1 diabetes

OBJECTIVE

To examine whether self-efficacy buffers the deleterious consequences of diabetes-specific family conflict on self-monitoring blood glucose (SMBG) and glycated hemoglobin (HbA1c) in youth with type 1 diabetes mellitus (T1DM).

METHODS

A total of 129 youth with T1DM (aged 10-16 years) completed measures of diabetes-specific family conflict and self-efficacy for diabetes management, and their blood glucose meter data and HbA1c were extracted from the electronic medical record. We preformed moderation analyses to examine whether self-efficacy moderated the association that diabetes-specific family conflict had with SMBG and HbA1c. We used simple slopes analyses to probe significant interactions.

RESULTS

Our results indicated that self-efficacy moderated the association that diabetes-specific family conflict had with SMBG and HbA1c. The pattern of these findings showed that high self-efficacy buffered the negative impact of diabetes conflict on HbA1c. However, benefits of high self-efficacy for more frequent SMBG was only apparent in the context of low diabetes-specific family conflict.

CONCLUSIONS

Study findings highlight the interactive relationship between diabetes-specific family conflict and self-efficacy in relation to SMBG and glycemic control. These findings suggest that family functioning and youth's self-efficacy are promising intervention targets for families having trouble with SMBG and HbA1c.

Evaluation of the Measurement Properties of Self-reported Medication Adherence Instruments Among People at Risk for Metabolic Syndrome: A Systematic Review

PURPOSE

The purpose of this study was to present a systematic review of available published studies that evaluated the measurement properties of self-reported instruments assessing global medication adherence in adults at risk for metabolic syndrome.

METHODS

The authors searched PubMed, EMBASE, PsycINFO, and CINAHL in January 2015 for appropriate studies. The methodological quality (based on reliability, validity, responsiveness, and interpretability) of selected studies was assessed with the COSMIN checklist (Consensus-Based Standards for the Selection of Health Measurement Instruments).

RESULTS

Of the 44 studies reviewed, 32 used classical test theory, and 14 used self-reported medication adherence instruments. More than half the studies included patients with hypertension, followed by diabetes, dyslipidemia, and increased body mass index. Among the measurement properties, internal consistency, hypothesis testing, and structural validity were frequently assessed items, whereas only 1 study evaluated responsiveness, and none evaluated measurement error. The MMAS-8 (Morisky Medication Adherence Scale-8 items) and the Hill-Bone scale were the most frequently used instruments. They were found to be well validated, with strong evidence for internal consistency and strong positive evidence for reliability, structural validity, hypothesis testing, and criterion validity.

CONCLUSIONS

The MMAS-8 and Hill-Bone scale seem to be well-validated instruments for assessing medication adherence in adults at risk for metabolic syndrome. These findings may assist clinicians with selecting the appropriate instruments for assessing medication adherence in this population. However, further studies might be needed to define concepts to better understand the dimensions of each medication adherence instrument.

Glycemic Control, Self-Efficacy and Fear of Hypoglycemia Among Iranian Children with Type 1 Diabetes

OBJECTIVE

This study was designed to test the reliability of a Persian version of 2 questionnaires to assess the level of fear of hypoglycemia (FoH) and self-efficacy in diabetes management and their association with glycated hemoglobin (A1C) and parents' demographic characteristics in a sample of children with type 1 diabetes.

DESIGN

We assessed 61 children with type 1 diabetes (35 boys and girls, 6.0 to 12.7 years of age) using the Hypoglycemia Fear Survey-Child version (HFS-C) and Self-Efficacy for Diabetes Scale-Child version (SED-C). Their glycemic control was evaluated by A1C levels.

RESULTS

The internal consistency of the Persian version of HFS-C and SED-C were very good. Our results showed that children older than 10 years of age report lower levels of FoH, which are related to higher levels of self-efficacy (r=-.30, p=0.025 and r=-.30, p=0.02, respectively). Of the children, 42.3% of girls and 31.4% of boys reported that low blood sugar is a big problem for them. These findings suggest that FoH is a significant concern for this target group. Only 19.7% of children had controlled diabetes based on A1C levels. There was no significant association between higher A1C levels and other variables, including HFS-C, SED-C and parents' demographic characteristics.

CONCLUSIONS

The Persian version of HFS-C and SED-C are reliable and valid measures of the fear of hypoglycemia and of self-efficacy in children with type 1 diabetes, and these questionnaires could be used in our country for identifying those children who may need diabetes education and other supports. The association between greater self-efficacy and lower fear of hypoglycemia suggests that addressing self-efficacy in diabetes education courses may be effective in helping to overcome FoH.

Developmental changes in the roles of patients and families in type 1 diabetes management

Developmentally-tailored diabetes self-care education and support are integral parts of contemporary multidisciplinary T1D care. The patient with T1D must have the support of the family and the diabetes team to maintain the rigors of diabetes management, but the specific roles of patients and families with regard to daily diabetes tasks change considerably throughout the developmental span of early childhood, middle childhood/school-age years, and adolescence. This review provides a framework of key normative developmental issues for each of these developmental stages. Within this context, ideal family diabetes management is reviewed within each developmental stage and anticipated challenges that can arise during these stages and that can adversely impact diabetes management are presented. This paper also summarizes empirical evidence for specific intervention and care strategies to support optimal diabetes management across these stages in order to maximize opportunities for a successful transfer of diabetes management tasks from parents to maturing youth. Finally, the review provides an emphasis on approaches to promote family teamwork and adolescent diabetes self-care adherence as well as opportunities to use novel technology platforms as a means to support optimal diabetes management.
