Pilot and feasibility of the SMART IBD mobile app to improve self-management in pediatric inflammatory bowel disease.

OBJECTIVES: Access to evidence-based self-management support in pediatric inflammatory bowel disease (IBD) is a significant challenge. Digital therapeutic solutions can increase access and provide data to patients and providers that would otherwise not be available. We have iteratively developed a mobile application, Self-Management Assistance with Recommended Treatment (SMART) IBD, that allows patients to access self-management support and record symptoms and medication adherence. METHODS: We conducted a pilot and feasibility study for this digital therapeutic tool in which patients used SMART IBD for 30 days. RESULTS: Results indicated that patients rated the app quality as good and accessed the app adequately overall, with some pages being used often. Medication adherence increased over the course of the study and was associated with sleep duration, mood, and stool consistency and blood content. CONCLUSIONS: Overall, this study demonstrated adequate feasibility for the SMART IBD app and initial findings suggest that additional research is needed to explore the potential impact of this tool in clinical care.

Systematic review and meta-analysis of interventions to promote medication adherence among children, adolescents, and young adults with medical conditions.

OBJECTIVE: This meta-analysis examined the efficacy of adherence-promotion interventions for children, adolescents, and young adults prescribed a medication for > 90 days as part of a treatment regimen for a medical condition. METHODS: A systematic literature review was conducted to identify randomized controlled trials of adherence-promotion interventions published between 2013 and 2023 and including children, adolescents, and/or young adults with a medical condition. A total of 38 articles representing 39 trials met inclusion criteria. A narrative synthesis was conducted to summarize included trials and a random-effects model was used to compute an overall intervention effect. Effect sizes by adherence outcome assessment methodology, participant age, and technology use were also computed. RESULTS: Pediatric adherence-promotion interventions demonstrate a medium effect with those randomized to an intervention displaying greater improvements in medication adherence than those randomized to a comparator condition (SMD = 0.46, 95% CI: 0.31, 0.60, n = 37; 95% Prediction Interval: -0.32, 1.23). CONCLUSIONS: Adherence interventions for children, adolescents, and young adults with medical conditions increase adherence.

Sedentary Behavior and Physical Activity Associated with Psychosocial Outcomes in Adolescents with Type 1 Diabetes.

Background: Adolescents with type 1 diabetes (T1D) are particularly vulnerable to poor psychosocial outcomes-high rates of diabetes distress and poor quality of life are common among this cohort. Previous work in the general population demonstrated positive associations between quality of life and increases in moderate-to-vigorous physical activity (MVPA), as well as decreased sedentary behavior. While survey-based assessments of young adults with T1D observed similar trends, these studies were limited by their use of subjective assessments of MVPA and sedentary behavior. The use of direct activity monitoring is needed to establish the association between psychosocial outcomes and MVPA and sedentary behavior among adolescents with T1D. Objective: To explore the association between objectively measured MVPA and sedentary behavior on psychosocial outcomes among adolescents with T1D. Subjects and Methods: The current study is a secondary analysis of baseline data collected for a pilot trial of sleep-promoting intervention for adolescents with T1D. Participants (n = 29, with a mean age of 15.9 ± 1.3 years) completed baseline surveys and wore an actigraph for a week following the baseline visit. We examined minutes per week of MVPA and proportion of awake time spent sedentary in relation to adolescents' diabetes distress, depressive symptoms, and diabetes-related quality of life. Results: Participants engaged in a mean of 19.6 ± 22.4 minutes of MVPA per day and spent 68.6 ± 9.9% of their awake time sedentary. MVPA was associated with lower diabetes distress in unadjusted (-3.6; 95% CI: -6.4 to -0.8) and adjusted (-2.6; 95% CI: -5.0--0.3) analyses. Sedentary time was associated with higher diabetes distress in adjusted (6.3; 95% CI: 1.3-11.2) but not unadjusted (6.0; 95% CI: -5.6-12.6) analyses. In secondary analyses, we did not observe significant associations between quality of life or depressive symptoms with either MVPA or sedentary behavior. Discussion: Our findings extend previous survey-based work demonstrating an association between decreased diabetes distress with greater weekly MVPA and lower sedentary time. The current study highlights the multifaceted benefits of physical activity in this population and provides preliminary evidence for developing interventions to reduce sedentary time as an alternative method to improve psychosocial outcomes in this at-risk population.

Use of Behavior Change Techniques and Quality of Commercially Available Inflammatory Bowel Disease Apps.

BACKGROUND: Inclusion of evidence-based behavior change techniques (e.g., self-monitoring) in mobile health apps has the potential to promote adherence to inflammatory bowel disease treatment. While inflammatory bowel disease management apps exist, the extent to which they incorporate behavior change techniques remains unknown. AIMS: The present study systematically evaluated the content and quality of free, commercially available inflammatory bowel disease management apps. METHODS: Apps were identified using a systematic search of the Apple App and Google Play stores. Apps were evaluated using Abraham and Michie's taxonomy of 26 behavior change techniques. A literature search was conducted to identify behavior change techniques specific and relevant for people with inflammatory bowel disease. App quality was assessed using the Mobile App Rating Scale with scores ranging from 1 (Inadequate) to 5 (Excellent). RESULTS: A total of 51 inflammatory bowel disease management apps were evaluated. Apps included 0-16 behavior change techniques (Mean = 4.55) and 0-10 inflammatory bowel disease management behavior change techniques (Mean = 3.43). App quality ranged from 2.03 to 4.62 (Mean = 3.39) out of 5.00. Two apps, My IBD Care: Crohn's & Colitis and MyGiHealth GI Symptom Tracker, included the highest number of overall and inflammatory bowel disease management behavior change techniques along with high-quality scores. Bezzy IBD was the only app with a high number of overall and inflammatory bowel disease management behavior change techniques with a primary focus on social support/change. CONCLUSION: Most inflammatory bowel disease management apps reviewed included evidence-based inflammatory bowel disease management behavior change techniques.

Sleep mHealth Applications and Behavior Change Techniques Evaluation.

OBJECTIVES: Mobile health apps may be an effective way to increase sleep management skills. Although little has been documented about the content and quality of available sleep management apps, providers often make app recommendations to help with sleep self-management. The objective of this study was to systematically evaluate the content and quality of commercially available sleep apps. METHODS: Following a systematic search of the Apple App and Google Play stores, 56 sleep management apps were evaluated. App content was evaluated using the taxonomy of behavior change techniques (BCTs), and app quality was assessed using the Mobile App Rating Scale. RESULTS: Sleep management apps included 0-15 BCTs (M = 6.89) and 0-9 sleep BCTs (M = 4.87). App quality ranged from 2.51 to 4.80 (M = 3.78) out of 5.00. Sleepiest Sleep Sounds Stories, ShutEye: Sleep Tracker, and Mintal Tracker: Sleep Recorder included the highest number of sleep BCTs and highest quality scores. CONCLUSIONS: While the content and quality of sleep management apps is variable, the findings are promising as many apps included a high number of BCTs and high quality. Although evidence of efficacy through randomized controlled trials is necessary to establish efficacy, this review can aid in app selection in the interim.

Longitudinal associations between family meal quality and quantity: Does one matter more for child, parent, and family health and well-being or are they synergistic?

It is unknown how family meal quantity (i.e., frequency) and quality (i.e., meal healthfulness and interpersonal quality) are associated with child, parent, and family health and well-being over time. This study aimed to examine longitudinal associations between family meal quantity and quality and child, parent, and family health and well-being and whether there was a synergistic effect between family meal quantity and quality. Children ages 5-9 and their parents from six racial/ethnic groups participated in this longitudinal cohort study. Regression models adjusted for socio-demographic characteristics examined family meal quantity, interpersonal quality, and nutritional quality at baseline and interactions between quantity and quality, in relation to changes in child, parent, and family health outcomes from baseline to 18-month follow-up. Higher family meal quantity predicted reduced obesity prevalence, improved diet quality and less food fussiness, food responsiveness, and conduct problems among children at follow-up. Higher family meal quality predicted improved diet quality, lower emotional problems, less food responsiveness, and fewer peer relationship problems among children, improved diet quality and reduced psychological distress for parents, and less family chaos at follow-up. One interaction between family meal quantity and quality was found for child peer relationship problems. Overall, family meal quantity and quality were independently important for child health and well-being and for some parent and family health outcomes. Clinicians working with families may want to emphasize the importance of both family meal quantity and quality, as these longitudinal findings suggest potential benefits for the entire family.

A systematic evaluation of primary headache management apps leveraging behavior change techniques.

BACKGROUND: Mobile health apps have the potential to promote adherence to headache management through the use of evidence-based behavior change techniques (e.g., self-monitoring). While many headache management apps exist, the extent to which these apps include behavior change techniques remains unknown. Thus, the present study systematically evaluated the content and quality of commercially available headache management apps. METHODS: Headache apps were identified using a systematic search in the Apple App and Google Play stores. A total of 55 apps were evaluated using the taxonomy of behavior change techniques and app quality using the Mobile App Rating Scale. RESULTS: Headache management apps included 0-14 behavior change techniques (Mean [M] = 5.89) and 0-8 headache management behavior change techniques (M = 4.29). App quality ranged from 2.84-4.67 (M = 3.73) out of 5.00. Three apps, Migraine Trainer, Easeday: Headache & Migraine, and PainScale, included the highest number of overall and headache management behavior change techniques along with good quality scores. CONCLUSIONS: While randomized controlled trials are necessary to determine the efficacy of individual headache apps, most existing apps include evidence-based headache management behavior change techniques. Headache apps often focus on either self-monitoring or stress management via relaxation training, suggesting that patients' needs should be used to inform app selection.

Digital headache self-management interventions for patients with a primary headache disorder: A systematic review of randomized controlled trials.

OBJECTIVE: This article systematically reviews the empirical literature examining the efficacy of digital headache management interventions for patients with a primary headache disorder. BACKGROUND: Digital headache management interventions provide opportunities to improve access to behavioral headache interventions to underserved groups. METHODS: A systematic search of PubMed, Scopus, and EBSCO (PsycInfo, Education Research Complete, ERIC, Health Source: Nursing/Academic Edition, Psychology and Behavioral Sciences Collection) and reference review was conducted. Included studies had to recruit a sample with a primary headache diagnosis, be a randomized controlled trial including a digital component, assess a headache outcome (i.e., frequency, duration, severity, intensity, disability) or quality of life, and be published in English. Two authors independently extracted data for included studies. The methodological quality of studies was assessed using the revised Cochrane risk-of-bias tool. RESULTS: Thirteen studies with unique interventions met inclusion criteria. More than half of the studies were pilots; however, nearly 70% (9/13) demonstrated significant between-group or within-group improvements on one or more headache-related outcomes. All interventions included some form of relaxation training and the majority were delivered via interactive website. While fewer than half the studies report participant race and/or ethnicity, of those that do, 83% (5/6) reported a predominately White/Caucasian sample. CONCLUSIONS: Efficacy testing of digital headache interventions is in its infancy with the majority of these studies relying on pilot studies with small samples comprised of homogenous patient populations. Interactive websites were the most common digital medium to deliver digital headache management interventions and have demonstrated promising results. Further testing using large-scale randomized controlled trials and exploration of other digital tools is warranted. Future studies with more diverse samples are needed to inform health equity of digital headache interventions.

Physical Activity, Glycemic Variability, and Parental Hypoglycemia Fear in Preschoolers With Type 1 Diabetes.

PURPOSE: The authors examined associations between preschoolers' daily glycemic variability, parents' report of hypoglycemia fear, and preschoolers' daily moderate to vigorous physical activity (MVPA) and sedentary behavior (SB) in 25 families of preschoolers with type 1 diabetes. METHODS: Parents completed a valid measure of hypoglycemia fear, and their child wore an accelerometer for up to 7 days. Parents provided glucose data from their child's devices. The authors used multiple regression and multilevel modeling to analyze their data. RESULTS: Preschoolers (mean age 4.2 [1.7] y; 50% boys) engaged in a mean of 154.5 (59.6) and 339.2 (85.1) minutes of MVPA and SB per day, respectively, and parents reported relatively low levels of hypoglycemia worry and avoidance behaviors. Preschoolers' SB (r = .19, P = .02) and MVPA (r = -.20, P = .01) levels were significantly correlated with parental hypoglycemia worry scores but not with parents' hypoglycemia behavior scores (P = .15 and P = .92, respectively). While multilevel models did not show an association between MVPA and preschoolers' glycemic variability, preschoolers who engaged in more daily SB experienced higher glycemic variability (P = .04). CONCLUSIONS: Research exploring MVPA, SB, and parental hypoglycemia fear in preschoolers with type 1 diabetes could have important clinical implications because it may reveal modifiable treatment targets that can impact preschoolers' health and activity patterns.

Associations Between Objective Sleep Behaviors and Blood Glucose Variability in Young Children With Type 1 Diabetes.

BACKGROUND: Young children with Type 1 diabetes (T1D) are at risk for extreme blood glucose variability, a risk factor for suboptimal glycated hemoglobin A1c (HbA1c) and long-term health complications. We know that a reciprocal relationship exists between sleep and glycemic outcomes in older youth with T1D; however, little research has examined objective sleep in young children (<7 years) with T1D. PURPOSE: This study examines bidirectional associations between sleep behaviors and glycemic variability in young children with T1D. METHODS: Thirty-nine young children with T1D (Mage 4.33 ± 1.46 years; MHbA1c 8.10 ± 1.06%) provided accelerometry data to objectively measure sleep onset latency, number of nighttime awakenings, and total sleep time. We also assessed HbA1c, average blood glucose, and glycemic variability (i.e., standard deviation of blood glucose from device downloads). We evaluated bidirectional relationships using multilevel modeling in SAS, with weekday/weekend as a Level 2 moderator. RESULTS: Children averaged 8.5 ± 1.44 hr of sleep per night, but only 12.8% met current sleep recommendations. Children experienced more nighttime awakenings, higher blood glucose, and more glycemic variability on weekends. Sleep onset latency and nighttime awakenings predicted greater glycemic variability on weekends, and weekend glycemic variability predicted increased nighttime awakenings. CONCLUSIONS: Most young children with T1D did not meet sleep recommendations. Young children experienced more nighttime awakenings, higher blood glucose, and increased glycemic variability on weekends only, when routines may be less predictable. Findings suggest that one way families of young children with T1D may be able to decrease glycemic variability is to keep consistent routines on weekdays and weekends.

Depression as a predictor of hypoglycemia worry in parents of youth with recent-onset type 1 diabetes.

BACKGROUND: During the recent-onset period of type 1 diabetes (T1D), parents may be at increased risk for depression, stress, and hypoglycemia fear; however, current studies have not examined the parental psychological experience and anxiety from hypoglycemia fear (ie, hypoglycemia worry) over time. This study examined the trajectory of parental hypoglycemia worry (Hypoglycemia Fear Survey-Worry [HFS-Worry]) in families of children with recent-onset T1D and the effects of baseline parental depression on parents' trajectory of HFS-Worry. METHODS: We enrolled 128 families of children ages 5- to 9-years-old with recent onset T1D in this study. At baseline, 125 parents completed measures of depression and HFS-Worry, followed by 111 at 6-month follow-up, 113 at 12-month follow-up, and 107 at 18-month follow-up. We used multilevel modeling to examine the 18-month trajectories of HFS-Worry and to examine if parental depression modified these trajectories. RESULTS: We found that parents HFS-Worry scores increased over time for parents with and without elevated depressive symptoms. Parents' baseline report of depression appeared to modify their trajectory of HFS-Worry over time such that parents with elevated depressive symptoms reported significantly higher levels of worry when compared to parents without depressive symptoms across the 18-month study period (P < .05). CONCLUSIONS: Parents of children with recent-onset T1D, who reported elevated depressive symptoms, reported higher HFS-Worry across the study period. Our findings suggest clinics should consider screening for parent depression and hypoglycemia worry following a T1D diagnosis. Integrating psychological screening for parents could help clinics to provide relevant treatment resources and tailor diabetes education for parents. Trial Registration NCT03698708.

Stressful life events, parental psychosocial factors, and glycemic management in school-aged children during the 1 year follow-up of new-onset type 1 diabetes.

OBJECTIVE: To monitor occurrence of stressful life events, assess correlations with family functioning and parental psychosocial measures, and examine the impact of stressful life events on diabetes management in the first year after diagnosis of type 1 diabetes (T1D) in children using a mixed methods design. METHODS: In a prospective study of 5- to 9-year-olds with recent-onset T1D (mean age 7.4 ± 1.3 years, T1D duration 4.7 ± 3.3 months), we monitored glycated hemoglobin A1c (HbA1c), income, job status, family health, and marital status at baseline and every 3 months up to 1 year. We measured coping, parental depression, and diabetes family conflict at baseline. RESULTS: Of 128 families, 53.9% (n = 69) reported 1+ stressful event, with 25.8% reporting income change (n = 33) during this period, 23.4% additional family health changes (n = 30), 22.7% job changes (n = 29), 21.9% changes in child's school (n = 28), and 3.9% changes in marital status (n = 5). Baseline active avoidance coping, parental depression, and diabetes family conflict correlated with a higher number of stressful life events (r = 0.239, P < .01; r = 0.197, P < .05; r = 0.225, P < .01, respectively). There were also cross-sectional associations between HbA1c and income decrease, school change, and job change at various time points in the study. CONCLUSIONS: Families can experience concurrent life stressors during the first year of T1D, which relate to coping, depression, and conflict. Consistent with existing literature, stressful life events relate to glycemic management. Future research should explore the individual's or parent's perception of stress and ways that diabetes centers can effectively assist families of youth with T1D and concurrent life stressors.

Society of Pediatric Psychology Workforce Survey: Updated Factors Related to Compensation.

OBJECTIVE: The 2017 Society of Pediatric Psychology (SPP) Workforce Survey provides self-reported compensation by pediatric psychologists, identifies predictors of compensation, and establishes a better understanding of compensation within the context of gender and race/ethnicity minority status. METHODS: SPP members who attended the SPP Annual Conference (SPPAC; April 2017) were invited to complete the survey at the conference through electronic tablets provided on-site by the Workforce Survey Committee. The survey was subsequently distributed online to SPP members who did not complete the survey at SPPAC. The statistical analyses used for this salary data employed flexible semi-parametric models, cross-validation, and prediction models for both the overall sample and academic rank subgroups. RESULTS: Of 27 potential demographic and employment-related predictors from the 2017 SPP Workforce Survey, significant predictors of salary emerged within this sample: academic rank, time since obtaining doctoral degree, managing internal and external funds (of at least $50,000), years in primary employment position, obtaining Fellowship status in the American Psychological Association (APA), and managing other employees (at least 10 people). Given low response rates for males and individuals who identify as belonging to racial and ethnic minority subgroups, only limited, exploratory results are reported for these subgroups. CONCLUSIONS: These findings suggest that not only is longevity in one's career important but managing funds/personnel and obtaining professional designations are also predictors of higher salaries for pediatric psychologists, in general. Specific implications of salary according to the psychologist's academic rank, gender, and racial/ethnicity group status are also explored.

Authoritarian parenting style predicts poorer glycemic control in children with new-onset type 1 diabetes.

OBJECTIVE: To examine cross-sectional and longitudinal associations among parenting styles (ie, authoritative, authoritarian, and permissive) and youth glycated hemoglobin (HbA1c) in a cohort of families of children with new-onset type 1 diabetes (T1D). METHODS: One-hundred two parents completed a baseline measure of parenting style, and we collected child HbA1c values at baseline and at three- and six-month follow-ups. We examined correlations among use of different parenting strategies and child HbA1cs. We conducted multiple regressions to assess the impact of these strategies on child HbA1c at three-month and six-month follow-ups, while controlling for baseline HbA1c, family income, and T1D duration. RESULTS: Correlational analyses showed negative associations between authoritative strategies and child HbA1c at baseline, three-month, and six-month assessments and positive associations between authoritarian strategies and child HbA1c at three-month and six-month assessments. Regression analyses found use of authoritarian-like strategies were the only parenting strategies associated with child HbA1c at three-month and six-month follow-ups, while controlling for baseline HbA1c, family income, and T1D duration. CONCLUSION: Parents' use of authoritarian-like strategies may negatively impact glycemic control over the course of six-month in children with new-onset T1D.

Historical Analysis: The Journal of Pediatric Psychology From 1976 to 2015.

Objective: To provide a historical analysis through the examination of trends in type of articles, content areas, and population groups across all issues of the Journal of Pediatric Psychology (JPP). Method: All articles published in JPP between the years 1976-2015 were coded based on article type (e.g., original research, meta-analysis), content code (e.g., adherence, primary care), and population code (e.g., oncology, chronic and recurrent pain). Descriptive statistics were calculated. Results: The overall top article types, content codes, and population codes are described as well as top codes for each decade. Overall, the majority of articles were classified as original research. Although some population and content codes varied over time, there were some areas that were consistently present throughout issues, including family systems, cognitive/intellectual functioning, pediatric oncology, and type 1 diabetes. Many topics selected for special issues and topics were consistent with top population and content codes. Conclusions: Findings indicate that most top areas have consistently been present in JPP over the 39-year period. The current historical analysis highlights these patterns as well as serves as a historical record for JPP.

Shared Responsibility for Type 1 Diabetes Care Is Associated With Glycemic Variability and Risk of Glycemic Excursions in Youth.

Objective: We examined how parent and youth responsibility for type 1 diabetes (T1D) care is related to adherence and glycemic outcomes, namely, glycemic variability and risk of glycemic excursions. Methods: One hundred thirty-five parent-youth dyads (10-16 years old; diagnosed with T1D for at least 6 months) participated in this study. Percent responsibility of T1D care attributed to the youth, parent, or shared was measured using the Diabetes Family Responsibility Questionnaire. We collected youth's hemoglobin A1c (HbA1c) and glucometer downloads to examine relationships between responsibility and HbA1c, frequency of blood glucose monitoring (self-monitoring blood glucose, SMBG), risk of glycemic excursions, and actual glycemic variability using bivariate correlations and path analysis. Results: Participants reported shared responsibility for almost half of T1D self-care tasks. Bivariate correlations showed shared responsibility was associated with less variability, whereas parent responsibility was associated with greater glycemic variability and risk for glycemic excursions. Youth responsibility was associated with lower frequency of SMBG. The path analyses confirmed our correlational findings (ps<.05) and better characterized interactions with age for youth-reported responsibility. Conclusions: Our results support the hypothesis that shared T1D responsibility is associated with better diabetes outcomes in youth.

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.

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.

Bidirectional Associations Between Psychological States and Physical Activity in Adolescents: A mHealth Pilot Study.

Objective: To understand the predictors and consequences of adolescent moderate-to-vigorous physical activity (MVPA) and sedentary behavior in nearly real-time. Methods: Participants were 26 adolescents ( M age = 15.96, SD = 1.56) who provided 80 self-reports of subjective states and continuous objective reports of MVPA and sedentary behavior over 20 days. Results: Random effects were observed for all of the models with affect and feeling variables predicting MVPA. There was a negative fixed effect for within-person positive affect and sedentary behavior and the inverse association for negative affect. Within-person MVPA was a significant positive predictor of positive affect and energy. There was a random effect for within-person MVPA and fatigue. There was a significant random effect for within-person sedentary behavior predicting positive affect. Within-person sedentary behavior was a significant negative predictor of energy. Conclusions: Findings highlight the importance of the intrapersonal nature of the associations among subjective states and physical activity.

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.
