The psychosocial outcomes of advanced hybrid closed-loop system in children and adolescents with type 1 diabetes.

The study was carried out to determine the psychosocial outcomes of advanced hybrid closed-loop (AHCL) systems in children and adolescents with type 1 diabetes (T1D). Single-center and cohort study with a duration 6 months consisted of 60 children and adolescents with T1D. Standard clinical procedures, including both glycemic indicators, e.g., sensor-measured time within the 70-180 mg/dL range and glycated hemoglobin (HbA1c) levels, and psychosocial metrics were used for data collection. The psychosocial metrics included the Pediatric Quality of Life Inventory (PedsQL) 3.0 Diabetes Module for both children (8-12 years) and parents; the Quality of Life for Youth scale for adolescents (13-18 years); the Strengths and Difficulties Questionnaire (SDQ); the Hypoglycemia Fear Survey for Children (HFS-C); the Revised Child Anxiety and Depression Scale (R-CADS); and AHCLS-specific DTSEQ satisfaction and expectation survey. These metrics were evaluated at the baseline and after 6 months of AHCL use. Of the 60 children and adolescents with T1D for whom the AHCL system was utilized, 41 of them, 23 female and 18 male, completed the surveys. The mean age of the 41 children and adolescents was 12.5 ± 3.2 (min. 6.7, max. 18) years. The time spent within the target glycemic range, i.e., time-in-range (TIR), improved from 76.9 ± 9% at the baseline to 80.4 ± 5% after 6 months of AHCL system use (p = 0.03). Additionally, HbA1c levels reduced from 7.1% ± 0.7% at the baseline to 6.8% ± 0.8% after 6 months of AHCL system use (p = 0.03). The most notable decline in HbA1c was observed in participants with higher baseline HbA1c levels. All patients' HFS-C and AHCL system-specific DTSEQ satisfaction and expectation survey scores were within the normal range at the baseline and remained unchanged during the follow-up period. No significant difference was found in the R-CADS scores of children and adolescents between baseline and after 6 months of AHCL system use. However, there was a significant decrease in the R-CADS scores of the parents. Patients' PedsQL scores were high both at the baseline and after 6 months. The SDQ scores were high at baseline, and there was no significant improvement at the end of 6 months.  Conclusion: This is the first study to investigate in detail the psychosocial outcomes of AHCL system use in T1D patients and their parents. Although state-of-the-art technologies such as AHCL provide patients with more flexibility in their daily lives and information about glucose fluctuations, the AHCL resulted in a TIR above the recommended target range without a change in QOL, HFS-C, SDQ, and R-CADS scores. The scores obtained from the R-CADS conducted by the parents of the children indicated that the use of pumps caused a psychological improvement in the long term, with a significant decrease in the R-CADS scores of the children and adolescents with T1D. What is Known: • Previous studies focused on clinical outcomes of AHCL systems in pediatric T1D patients, showing glycemic control improvements. • Limited attention given to psychosocial outcomes of AHCL systems in children and adolescents with T1D. • Crucial psychosocial factors like quality of life, emotional well-being, and fear of hypoglycemia underexplored in AHCL system context. What is New: • First study to comprehensively examine psychosocial outcomes of AHCL systems in pediatric T1D patients. • Study's robust methodology sets new standard for diabetes technology research and its impact on qualiy of life.

Role perceptions and experiences of adult children in remote glucose management for older parents with type 2 diabetes mellitus: a qualitative study.

BACKGROUND: With the advent of the smart phone era, managing blood glucose at home through apps will become more common for older individuals with diabetes. Adult children play important roles in glucose management of older parents. Few studies have explored how adult children really feel about engaging in the glucose management of their older parents with type 2 diabetes mellitus (T2DM) through mobile apps. This study provides insights into the role perceptions and experiences of adult children of older parents with T2DM participating in glucose management through mobile apps. METHODS: In this qualitative study, 16 adult children of older parents with T2DM, who had used mobile apps to manage blood glucose for 6 months, were recruited through purposive sampling. Semi-structured, in-depth, face-to-face interviews to explore their role perceptions and experiences in remotely managing their older parents' blood glucose were conducted. The Consolidated Criteria for Reporting Qualitative Research (COREQ) were followed to ensure rigor in the study. The data collected were analyzed by applying Colaizzi's seven-step qualitative analysis method. RESULTS: Six themes and eight sub-themes were identified in this study. Adult children's perceived roles in glucose management of older parents with T2DM through mobile apps could be categorized into four themes: health decision-maker, remote supervisor, health educator and emotional supporter. The experiences of participation could be categorized into two themes: facilitators to participation and barriers to participation. CONCLUSION: Some barriers existed for adult children of older parents with T2DM participating in glucose management through mobile apps; however, the findings of this study were generally positive. It was beneficial and feasible for adult children to co-manage the blood glucose of older parents. Co-managing blood glucose levels in older parents with T2DM can enhance both adherence rates and confidence in managing blood glucose effectively.

The role of emotion dysregulation in self-management behaviors among adults with type 2 diabetes.

Suboptimal disease self-management among adults with type 2 diabetes is associated with greater risk of diabetes related health complications and mortality. Emotional distress has been linked with poor diabetes self-management; however, few studies have examined the role of emotion dysregulation in diabetes management. The purpose of this study was to examine the relations between different facets of emotion dysregulation and diabetes self-management behaviors among a sample of 373 adults with type 2 diabetes. Separate median regression and binary logistic regression models were used to examine the association of emotion dysregulation facets and each diabetes self-care behavior (i.e., medication nonadherence, diet, exercise, self-monitoring of blood glucose (SMBG), foot care, and smoking). Generally, greater difficulties in emotion regulation were associated with poorer self-management behaviors. However, several facets of emotion dysregulation were linked with better self-management behaviors. Addressing emotion dysregulation among adults with type 2 diabetes has the potential to improve diabetes related self-management.

Unveiling the interplay between rational, psychological and functional factors in continuous glucose monitoring early adoption: Novel evidence from the Dexcom ONE case in Italy.

BACKGROUND: The escalating prevalence of diabetes, with its multifaceted complications, poses a pressing challenge for healthcare systems globally. In response, the advent of continuous glucose monitoring (CGM) systems, offering technological solutions for daily diabetes management, presents significant opportunities. However, the widespread adoption faces several barriers, linked both to the technological configuration of the devices and to the psychological dimension of patients. Therefore, this study aims to apply and test a theoretical model that investigates the antecedents of the intention to use Continuous Glucose Monitoring systems. METHODS: The research model was built to unveil the impacts of psychological factors, functional components and rational constructs derived from the Technology Acceptance Model (TAM) on CGM systems sustained adoption. To ensure the comparability of results, we have collected data from people who had used Dexcom ONE Dexcom (San Diego, CA) for the first time for at least one month. Employing Structural Equation Modelling (SEM) techniques, the hypothesized relationships among constructs were assessed. RESULTS: The analyses confirmed the positive correlation of rational factors to the Intention to Use. Subjective Norm, intended as the physicians' influence, is positively correlated with the Perceived Usefulness. Trend Arrows, albeit being negatively correlated with Perceived Usefulness, have a positive correlation on Perceived Ease Of Use, reinforcing its mediating effect towards Perceived Usefulness. Among psychological factors, Trust in the CGM technology positively correlates with Intention to Use. Health Literacy is negatively correlated to the Intention to Use. CONCLUSIONS: These findings contribute to theoretical and managerial understanding, providing recommendations to enhance the adoption of CGM systems like Dexcom ONE.

Continuous glucose monitoring with data sharing in older adults: A qualitative study.

AIMS: This study examined the perceptions of the SHARE plus intervention and its effects on communication, collaboration, and involvement in day-to-day diabetes management in older adults with Type 1 diabetes (T1D) and their care partners. BACKGROUND: The SHARE plus intervention includes continuous glucose monitoring with a data sharing app that allows care partners to view glucose data on a smartphone and receive alerts. People with T1D and their care partners are educated about communication strategies, problem-solving strategies, and action planning when using glucose data sharing. DESIGN: Qualitative descriptive design. METHODS: Older adults with T1D wore a continuous glucose monitor for 3 months (n = 10). Care partners (n = 10) used a data-sharing app. The SHARE plus intervention consisted of one 90-min education session. Semi-structured interviews were conducted across 10 dyads (person with diabetes and care partner) following the 12-week study. A qualitative description and a constant comparison approach were used to examine similarities and differences in experiences. Interviews were transcribed, coded, and analysed for common themes. The manuscript adheres to COREQ EQUATOR checklist. RESULTS: The SHARE plus intervention increased diabetes knowledge across the dyads, improving confidence and helping partners understand how to navigate symptoms and behaviours and when to intervene. Dyads worked together to optimise diabetes management through improved communication, collaboration, and management of disagreements. Although the majority of persons with diabetes and their care partners reported no conflictual communication, disagreements about diabetes management remained in some dyads. The SHARE plus intervention impacted care partners in various ways from a psychological perspective. While live-in-care partners felt peace of mind, care partners living away from persons with diabetes had some increased worry and concern. CONCLUSION: The SHARE plus intervention results can help guide future development of diabetes dyadic care and education interventions using diabetes technology. RELEVANCE TO CLINICAL PRACTICE: The SHARE plus intervention is a brief, practical intervention that can help diabetes clinicians improve communication and collaboration among spouses living with older adults with T1D who use continuous glucose monitoring with data sharing. PATIENT CONTRIBUTION: A person with diabetes was part of the research team and assisted with design of the intervention and subsequent interviews and analysis.

Monetary reinforcement for self-monitoring of blood glucose among young people with type 1 diabetes: evaluating effects on psychosocial functioning.

AIMS: To explore the auxiliary psychosocial effects of a monetary reinforcement intervention targeting self-monitoring of blood glucose among young people with Type 1 diabetes. METHODS: Sixty young people with Type 1 diabetes, HbA1c concentrations between 58 and 119 mmol/mol (7.5-13.0%), and average self-monitoring of blood glucose <4 times per day were randomized to either enhanced usual care or a 24-week intervention of monetary rewards for self-monitoring of blood glucose and associated behaviours (e.g. uploading glucose meters). Data were collected from the young people and their parents at baseline, during the intervention (6, 12 and 24 weeks) and after the intervention (36 weeks). RESULTS: Linear mixed models were used to evaluate the intervention effects on psychosocial outcomes, adjusting for corresponding baseline levels and potential moderation by baseline level. The intervention reduced diabetes distress at week 6 among young people who had average and high baseline distress. It also reduced diabetes distress at weeks 12 and 24 among those with low baseline distress. The intervention also reduced young person-reported diabetes-related family conflict and diabetes-related interference among those with high baseline scores in these areas; however, the intervention worsened young person-reported diabetes interference among those with low baseline interference. Effects were medium-sized and time-limited. CONCLUSIONS: Findings indicate predominantly positive impacts of monetary reinforcement interventions on psychosocial outcomes, although effects varied by outcome and time point. Whereas early improvements in diabetes distress were observed for all who received the intervention, improvements in other areas varied according to the level of psychosocial challenge at baseline. Incorporating psychosocial interventions may bolster and maintain effects over time.

Social Media in the Diabetes Community: a Novel Way to Assess Psychosocial Needs in People with Diabetes and Their Caregivers.

PURPOSE OF REVIEW: Diabetes is a chronic disease that, regardless of type, requires intensive, ongoing self-management. As a result, people with diabetes (PWD) often have complex environmental, social, behavioral, and informational needs, many of which are unmet in healthcare settings and systems. To help meet these needs, many PWD interact with diabetes online communities (DOCs), including platforms such as Facebook, Twitter, and blogs, to share real-life support, problems, and concerns with other PWD, offering a rich source of data on patient-reported outcomes. This article reviews recent psychosocial needs and outcomes identified by studies of DOCs and/or their users. RECENT FINDINGS: Participation in DOCs appears driven by a need for psychosocial support, unmet by providers and the healthcare system, as well as a sense of duty to provide it to others. The most common activities observed in DOCs are giving and receiving various types of support: psychosocial, technical, informational, and self-management. General and specific challenges (e.g., continuous glucose monitoring) as well as frustrations and worries associated with those challenges are commonly expressed, leading to reciprocal sharing, support, and encouragement, in a judgment-free manner, from other PWD. This leads users to feel more understood, empowered, validated, less alone, and more supported. Negative findings were reported very rarely and focused more on how other participants used social media rather than on the exchange of misplaced or dangerous information or advice. Diabetes online communities have grown from unmet needs for problem-solving and psychosocial support for living with a complex condition and from the availability of a new communications medium (i.e., social media). This has enabled communities of peers to both seek and receive support for living with diabetes, providing an important supplement to what is provided in healthcare settings and offering valuable information about what is most important to PWD and their families, with the potential to improve psychosocial care.

How Do the Challenges of Emerging Adulthood Inform our Understanding of Diabetes Distress? An Integrative Review.

PURPOSE OF REVIEW: Emerging adulthood (ages 18-29) presents many emotional, social, and developmental challenges that can contribute to an increased sense of burden when managing type 1 diabetes (T1D). Diabetes distress (DD) is the concept that captures the emotional burden, frustrations, and worries resulting from living with T1D. This integrative review sets out to examine the impact of developmental context by answering this question: How do the challenges of emerging adulthood inform our understanding of DD? RECENT FINDINGS: DD is highly prevalent in emerging adults and occurs at higher rates than in other age groups. Qualitative studies reveal that DD is embedded within the developmental challenges specific to living with T1D during this stage. Quantitative studies reveal the prevalence and correlates of DD in this age group, and qualitative studies augment these findings by capturing the scope and complexity of the emotional burden of living with T1D as an emerging adult.

Diabetes care: addressing psychosocial well-being in young adults with a newly developed assessment tool.

BACKGROUND: Psychosocial assessment should be part of clinic visits for people with diabetes mellitus (DM). AIMS: To assess the usage and acceptance of a diabetes psychosocial assessment tool (DPAT) and to profile the clinical and psychosocial characteristics of young people with diabetes. METHODS: Over a 12-month period, young adults (18-25 years) attending diabetes clinic were offered DPAT. The tool embeds validated screening tools including the Problem Areas in Diabetes 20 (PAID-20) questionnaire, the Patient Health Questionnaire-4 (PHQ-4) and the World Health Organization Well-Being Index-5 (WHO-5). Baseline clinical data were collected and questions regarding social support, body image, eating concerns, hypoglycaemia and finances were included. RESULTS: Over the 12 month, the form was offered to 155 participants (64.6% of eligible attendees). The majority (96.1%) had type 1 DM with a mean duration of 10.5 (±5.3 SD) years. Average glycated haemoglobin (HbA1c) was 8.7% (±1.5 SD) (or 71.2 mmol/mol ±16.5 SD). Severe diabetes-related distress (PAID-20 ≥ 40) was found in 19.4%. Low WHO-5 scores (28-50 points) were seen in 14.8%. PHQ-4 identified 25.8% with anxiety and 16.1% with depression. Significant weight, shape and eating concerns were identified in 27.1, 26.6 and 28.4%, respectively. Serious hypoglycaemia concerns were raised by 4.5%. CONCLUSION: DPAT revealed a high prevalence of psychosocial stress among young adults with DM. The tool was easy to use and accepted by patients and may aid streamlining referrals to relevant members of a multidisciplinary team.

Evaluating Feasibility of Personal Diabetes Device Data Collection for Research.

BACKGROUND: Diabetes devices, like insulin pumps and continuous glucose monitors (CGMs), capture and store patient adherence and utilization data that can be retrieved or downloaded providing objective information on self-management behaviors; yet, diabetes device data remain underutilized in research. OBJECTIVE: The aim of the study was to examine the usability and feasibility of personal diabetes device data collected using a clinical download platform retooled for research purposes. METHODS: Investigators evaluated the feasibility of raw diabetes device data collection. One hundred eight preteens and adolescents with Type 1 diabetes and their parents provided consent/assent. RESULTS: Data were successfully collected from the diabetes devices (insulin pumps and CGM) of 97 youth using a clinical download software adapted for research, including data from all three commercially available CGM systems and insulin pumps brands, which contained all current and previous models of each insulin pump brand. The time required to download, mode of connection, and process varied significantly between brands. Despite the use of an agnostic download software, some outdated device brands and cloud-based CGM data were unsupported during data collection. Within the download software, dummy clinical accounts were created for each study participant, which were then linked back to a master study account for data retrieval. Raw device data were extracted into seven to eight Excel files per participant, which were then used to develop aggregate daily measures. DISCUSSION: Our analysis is the first of its kind to examine the feasibility of raw diabetes device data using a clinical download software. The investigators highlight issues encountered throughout the research process, along with mitigating strategies to inform future inquiry. CONCLUSION: This study demonstrates the feasibility of raw data collection, from a wide variety of insulin pump and CGM brands, through the retooling of a clinical download software. Data from these personal devices provide a unique opportunity to study self-management behavior and the glycemic response of individuals in their everyday environments.

Modelling individual, parental and peer factors to glycaemic control in adolescents with type 1 diabetes: A prospective study.

AIM: To construct a model addressing the pathways from baseline diabetes distress, attribution of peer reactions, parenting style and 3-month self-management to 6-month glycated haemoglobin levels in adolescents with type 1 diabetes. DESIGN: A prospective design was adopted. METHODS: A total of 177 adolescents aged 10-19 with type 1 diabetes were enrolled from four hospitals in Taiwan. Diabetes distress, attribution of peer reactions and parenting style were collected at baseline, self-management was collected at the third month and glycated haemoglobin levels were collected at the sixth month. Data were collected from May 2015-June 2016. RESULTS: Baseline diabetes distress and 3-month self-management directly affected 6-month glycated haemoglobin levels. Baseline attribution of peer reactions directly affected baseline diabetes distress and 3-month self-management; also, it indirectly affected 6-month glycated haemoglobin levels through 3-month self-management. Baseline parenting style directly affected baseline diabetes distress, baseline attribution of peer reactions, 3-month self-management and 6-month glycated haemoglobin levels; it also indirectly affected 6-month glycated haemoglobin levels through baseline diabetes distress and 3-month self-management. CONCLUSION: A model simultaneously incorporating individual, parental and peer factors to glycaemic control in adolescents with type 1 diabetes has been constructed. Improving diabetes distress and self-management should be essential strategies to improve glycaemic control in adolescents with type 1 diabetes. Encouraging adolescents with type 1 diabetes to communicate openly with peers about diabetes care and educating their parents to provide more responsive and autonomy-encouraging parenting style might be vital strategies to improve diabetes distress, 3-month self-management and glycaemic control. IMPACT: Individual, parental and peer factors should be simultaneously considered to improve glycaemic control in adolescents with type 1 diabetes. Nurses should evaluate these factors to tailor interventions improving glycaemic control in adolescents with type 1 diabetes.

Sleep, self-management, neurocognitive function, and glycemia in emerging adults with Type 1 diabetes mellitus: A research protocol.

Type 1 Diabetes (T1D) affects 1.6 million Americans, and only 14% of emerging adults ages 18-25 years achieve targets for glycemic control (A1C < 7.0%). Sleep deficiency, including habitual short sleep duration (<6.5 hr total sleep time and high within-person variability in total sleep time), is associated with poorer glycemic control. Emerging adults with T1D have a more pronounced sleep extension on weekends compared with matched controls, consistent with sleep deficiency; however, associations among sleep variability and glycemic control have not been explored in this population. Sleep deficiency may affect the complex higher-order neurocognitive functioning needed for successful diabetes self-management (DSM). We report the protocol for an ongoing study designed to characterize sleep and the associations among sleep deficiency, neurocognitive function, DSM, diabetes quality of life, and glycemia among a sample of 40 emerging adults with T1D. We monitor sleep via wrist-worn actigraphy and glucose via continuous glucose monitoring concurrently over 14 days. We are collecting data on self-report and objective sleep, a 10-min psychomotor vigilance test on a PVT-192 device, a 3-min Trail Making Test on paper, and questionnaires, including twice-daily Pittsburgh sleep diaries using Research Electronic Data Capture (REDCap)TM . Results from this study will be used to support the development and testing of the efficacy of a tailored sleep self-management intervention that may improve total sleep time, sleep variability, neurocognitive function, DSM, glycemic control, and glucose variability among emerging adults with T1D.

Making sense of blood glucose data and self-management in individuals with type 2 diabetes mellitus: A qualitative study.

AIMS AND OBJECTIVES: To describe individuals' with type 2 diabetes mellitus sense-making of blood glucose data and other influences impacting self-management behaviour. BACKGROUND: Type 2 diabetes mellitus prevalence is increasing globally. Adherence to effective diabetes self-management regimens is an ongoing healthcare challenge. Examining individuals' sense-making processes can advance staff knowledge of and improve diabetes self-management behaviour. DESIGN: A qualitative exploratory design examining how individuals make sense of blood glucose data and symptoms, and the influence on self-management decisions. METHODS: Sixteen one-on-one interviews with adults diagnosed with type 2 diabetes mellitus using a semi-structured interview guide were conducted from March-May 2018. An inductive-deductive thematic analysis of data using the Sensemaking Framework for Chronic Disease Self-Management was used. The consolidated criteria for reporting qualitative research (COREQ) checklist were used in completing this paper. RESULTS: Three main themes described participants' type 2 diabetes mellitus sense-making and influences on self-management decisions: classifying blood glucose data, building mental models and making self-management decisions. Participants classified glucose levels based on prior personal experiences. Participants learned about diabetes from classes, personal experience, health information technology and their social network. Seven participants expressed a need for periodic refreshing of diabetes knowledge. CONCLUSION: Individuals use self-monitored glucose values and/or HbA1C values to evaluate glucose control. When using glucose values, they analyse the context in which the value was obtained through the lens of personal parameters and expectations. Understanding how individuals make sense of glycaemic data and influences on diabetes self-management behaviour with periodic reassessment of this understanding can guide the healthcare team in optimising collaborative individualised care plans. RELEVANCE TO CLINICAL PRACTICE: Nurses must assess sense-making processes in self-management decisions. Periodic "refresher" diabetes education may be needed for individuals with type 2 diabetes mellitus.

Contribution of structured self-monitoring of blood glucose to self-efficacy in poorly controlled diabetes patients in China.

AIM: To investigate the association between structured self-monitoring of blood glucose (SMBG) and diabetes self-efficacy in Chinese patients. METHODS: This study was a single-centre, open-label, prospective, randomized controlled trial. A total of 250 type 1 and type 2 diabetes patients were recruited and randomly assigned to the structured SMBG group and the control group in a 1:1 ratio. The main outcome observed in this subgroup analysis was a change in the diabetes self-efficacy scale (DSES) scores. A multivariate generalized estimating equation was used to evaluate factors affecting the DSES scores. RESULTS: We found that the DSES scores tended to decrease significantly with the follow-up time in the intervention group (Wald ß = 7.882, P < .001; Wald ß = 3.130, P = .003; Wald ß = 7.879, P < .001). However, no significant differences in the DSES scores were detected in the control group. Glycaemic control improved in both the intervention and control groups at the third month (P < .05). In the intervention group, sustained improvement of the DSES scores maintained the improvement in glycaemic control through the sixth month. In the control group, glycaemic control tended to deteriorate in the sixth month without the support of an improved DSES scores (P = .056). CONCLUSION: Structured SMBG could contribute to the effective and persistent improvement of diabetes self-efficacy. (ClinicalTrials.gov, NCT02225691).

The impact of using a closed-loop system on food choices and eating practices among people with Type 1 diabetes: a qualitative study involving adults, teenagers and parents.

AIMS: We explored whether, how and why moving onto and using a hybrid day-and-night closed-loop system affected people's food choices and dietary practices to better understand the impact of this technology on everyday life and inform recommendations for training and support given to future users. METHODS: Twenty-four adults, adolescents and parents were interviewed before commencing use of the closed-loop system and following its 3-month use. Data were analysed thematically and longitudinally. RESULTS: While participants described preparing and/or eating similar meals to those consumed prior to using a closed-loop, many described feeling more normal and less burdened by diabetes in dietary situations. Individuals also noted how the use of this technology could lead to deskilling (less precise carbohydrate counting) and less healthy eating (increased snacking and portion sizes and consumption of fatty, energy-dense foods) because of the perceived ability of the system to deal with errors in carbohydrate counting and address small rises in blood glucose without a corrective dose needing to be administered. CONCLUSIONS: While there may be quality-of-life benefits to using a closed-loop, individuals might benefit from additional nutritional and behavioural education to help promote healthy eating. Refresher training in carbohydrate counting may also be necessary to help ensure that users are able to undertake diabetes management in situations where the technology might fail or that they take a break from using it.

The Relationship Between a Balanced Time Perspective and Self-monitoring of Blood Glucose Among People With Type 1 Diabetes.

Background: Self-monitoring of blood glucose helps people with type 1 diabetes to maintain glycemic control and reduce the risk of complications. However, adherence to blood glucose monitoring is often suboptimal. Purpose: Like many health behaviors, self-monitoring of blood glucose involves exerting effort in the present to achieve future benefits. As such, the present research explored whether individual differences in time perspective-specifically, the extent to which people have a balanced time perspective-are associated with the frequency with which people with type 1 diabetes monitor their blood glucose and, thus, maintain glycemic control. Methods: Adults with type 1 diabetes completed measures of time perspective, feelings associated with monitoring, attitudes toward monitoring, and trait self-control. Objective data regarding the frequency with which participants monitored their blood glucose levels and their long-term glycemic control were extracted from their medical records. Results: Hierarchical regression analyses and tests of indirect effects (N = 129) indicated that having a more balanced time perspective was associated with more frequent monitoring of blood glucose and, as a result, better glycemic control. Further analyses (N = 158) also indicated that there was an indirect relationship between balanced time perspective and monitoring of blood glucose via the feelings that participants associated with monitoring and their subsequent attitudes toward monitoring. Conclusions: These findings point to the importance and relevance of time perspective for understanding health-related behavior and may help to inform interventions designed to promote self-monitoring of blood glucose in people with type 1 diabetes.

Assessing strengths of children with type 1 diabetes: Validation of the Diabetes Strengths and Resilience (DSTAR) measure for ages 9 to 13.

BACKGROUND: Adaptive diabetes-specific attitudes and behaviors, known as diabetes strengths, relate to positive self-management and quality of life outcomes in type 1 diabetes (T1D), but have not been studied in preadolescence. To facilitate strengths-based care and research on this topic, we developed and evaluated the psychometric properties of a measure of diabetes strengths for children age 9 to 13. METHODS: Participants were 187 children receiving care for T1D at a tertiary care children's hospital. They completed the 12-item self-report Diabetes Strengths and Resilience scale for children (DSTAR-Child), which we adapted from a measure validated for adolescents. Youth completed the DSTAR-Child twice, and measures of relevant constructs at baseline: general and diabetes-related quality of life, depressive symptoms, and diabetes distress. Parents rated children's engagement in self-management behaviors and general resilience. We extracted HbA1c from the medical record. RESULTS: The DSTAR-Child total score demonstrated reliability, including internal consistency and stability across two time points. The total score was significantly associated in expected directions with psychosocial measures and glycemic control but not self-management behaviors. In confirmatory factor analyses, the best-fitting structure contained two latent factors tapping intrapersonal and interpersonal strengths. Resulting subscale scores also appeared reliable and valid. CONCLUSIONS: This brief, practical measure of diabetes strengths demonstrated sound psychometric properties. Diabetes strengths appeared unrelated to self-management behaviors, perhaps because of the primary role of adult caregivers in T1D management for preadolescents. As a research and clinical tool, the DSTAR-Child can facilitate greater understanding of diabetes strengths and inform strengths-based strategies to foster resilient T1D outcomes.

Glucose management for rewards: A randomized trial to improve glucose monitoring and associated self-management behaviors in adolescents with type 1 diabetes.

BACKGROUND: This randomized, controlled trial evaluated a monetary-based reinforcement intervention for increasing self-monitoring of blood glucose (SMBG) among youth with poorly controlled type 1 diabetes. METHODS: After a 2-week baseline, 60 participants were randomized to enhanced usual care (EUC) or Reinforcers. The Reinforcers group earned monetary rewards for SMBG and associated behaviors such as uploading glucose meters. Reinforcers were withdrawn at 24 weeks. A follow-up evaluation occurred at 36 weeks. RESULTS: Participants in the reinforcers group increased the proportion of days they completed ≥4 SMBG from 14.6% at baseline to 64.4%, 47.5%, and 37.8% at 6, 12, and 24 weeks, respectively. In contrast, EUC participants declined from 22.7% at baseline to 17.5%, 10.5%, and 11.1% (Ps < .01 vs EUC at all time points). Group differences were attenuated but remained significant after withdrawal of reinforcers. Effect sizes for SMBG were very large during reinforcement and large after withdrawal of reinforcers. In the reinforcers group, mean A1c dropped from 9.5% ± 1.2% at baseline to 9.0% ± 1.3% at week 6 and 9.0% ± 1.4% at week 12. For EUC, A1c was 9.2% ± 0.2% at baseline and ranged from 9.2% ± 1.5% to 9.6% ± 1.6% throughout the study (P < .05 vs EUC). Group differences in A1c were no longer significant at weeks 24 and 36. Effect sizes for A1c were small during reinforcement and also after withdrawal of reinforcement. CONCLUSIONS: Monetary-based reinforcement of adolescents with type 1 diabetes caused durable increases in SMBG. Modification of the reinforcement structure may be needed to sustain improved metabolic control in this challenging age group.

Randomized Trial of a Positive Psychology Intervention for Adolescents With Type 1 Diabetes.

OBJECTIVE: To evaluate the effects of a positive psychology intervention for adolescents with type 1 diabetes (T1D) on adherence, glycemic control, and quality of life. METHODS: Adolescents with T1D (n = 120) and their caregivers were randomized to either an Education (EDU) (n = 60) or Positive Affect (PA) intervention (n = 60). Adolescents in the PA group received the intervention reminders (gratitude, self-affirmation, parental affirmation, and small gifts) via text messages or phone calls over 8 weeks. Questionnaires were completed by adolescents and caregivers and clinical data (glucometer and HbA1c) were collected at baseline 3 and 6 months. Data were analyzed using generalized linear modeling. RESULTS: After adjusting for covariates, adolescents in the PA group demonstrated significant improvement in quality of life at 3 months, compared to the EDU group, but this was not sustained at 6 months. Similarly, the PA group showed a significant decrease in disengagement coping at 3 months but not at 6 months. There was no significant intervention effect on blood glucose monitoring, but the odds of clinically significantly improvement (checking at least one more time/day) were about twice as high in the PA group as the EDU group. No significant effects were found for glycemic control. CONCLUSIONS: A positive psychology intervention had initial significant, positive effects on coping and quality of life in adolescents with T1D. A more intensive or longer-lasting intervention may be needed to sustain these effects and to improve adherence and glycemic control.

Adolescent Emotional Control Moderates Benefits of a Multicomponent Intervention to Improve Type 1 Diabetes Adherence: A Pilot Randomized Controlled Trial.

Objective: We previously tested via randomized controlled trial a novel intervention for adolescents with type 1 diabetes and above-target glycemic control that combined web-delivered incentives for self-monitoring of blood glucose (SMBG) and brief web counseling with working memory training and parental contingency contracting training. Results showed improved SMBG and decreased glycosylated hemoglobin (HbA1c) at 6- and 12-month follow-ups. However, it has not been elucidated if improvements in SMBG mediated the immediate benefits of this treatment on HbA1c nor if this intensive intervention uniquely benefited a subgroup of adolescents with higher problems in emotional control. Methods: Adolescents with type 1 diabetes and above-target glycemic control (n = 61) were randomized to receive the 6-month intervention (n = 30) or usual care (n = 31). Adolescents completed the Behavior Rating Inventory of Executive Function-Self-Report, problems with emotional control subscale at baseline, and provided meter downloads to assess frequency of SMBG and completed an HbA1c blood draw at baseline and 6 months later. Results: At 6-month follow-up, improvements in SMBG mediated the effects of receiving the treatment on having lower average HbA1c. Further, problems in emotional control moderated the benefits of the intervention on improvements in SMBG and in turn HbA1c. Only adolescents with above average problems in emotional control evidenced improvements in SMBG in response to treatment, which then explained lower HbA1c levels at 6-month follow-up. Conclusions: This multicomponent, web-delivered intervention provided unique benefits for improving SMBG and lowering HbA1c in teens with higher problems in emotional control.
