Clinical Trial Summary

This pilot study will examine the feasibility, acceptability, and preliminary efficacy of the intervention. This will ensure that all aspects of the research protocol and procedures work as desired and are acceptable to families in preparation for the fully powered randomized controlled trial. The proposed study will assess our ability to: 1)recruit, consent, and retain participants, 2) deliver the intervention, 3) implement study and assessment procedures 4) assess the reliability of the proposed measures in this sample, 5) determine whether modifications to the intervention, procedures, and measures are needed prior to conducting a fully powered study, and 6) willingness of participants to participate in the intervention.


Description:

The current study employs a 2 group randomized control design (treatment and no-treatment control) with randomization occurring after baseline (time 0) and 3 additional evaluation periods (end of intervention (time 1), and 9 months (time 2) and 12 months post intervention (time 3)). Because the the i♥rhythm project is intended to prevent children from beginning a trajectory toward overweight/obesity in elementary school, the impact of the intervention on change in standardized BMI (BMIz) during the following summer (time 2 and 3) will be explored, identifying whether a maintenance intervention is needed. Following the intervention and final data assessment (time 1 and 3), qualitative interviews will explore the acceptability of the intervention, treatment barriers and facilitators, difficulties with study procedures, maintenance of improvements, and self-efficacy to maintain improvements. A third treatment condition controlling for the effect of attention was beyond the scope of the current feasibility study.

Outcome

Type Measure Description Time frame Safety issue
Primary Feasibility Criteria: ability to recruit the needed sample size The feasibility of the intervention will be established by our ability to recruit the needed sample size and retain at least 80% at Time 1 and 60% at Time 3; favorable acceptability ratings by 80% of the sample, participation in greater than 60% of daily diaries, views of intervention materials by 80% of participants. Decisions regarding changes to the intervention will be made based on the attainment of feasibility criteria and post-assessment interviews. Decisions regarding changes to the intervention will be made based on the attainment of feasibility criteria and post-assessment interviews. 3 months
Primary Treatment Acceptability Treatment Acceptability Report Form-Revised(TARF-R) 185 is a 20-item global measure of treatment acceptability for behavioral interventions. The TARF-R has demonstrated good internal consistency (as>.69) and evidence of construct validity. A favorable rating is considered 4 or greater. 3 months
Secondary Anthropometrics Body Mass Index (BMI) is the most common indicator of body size and has been consistently correlated with metabolic problems in children. Participants' height and weight will be measured using established protocols. BMI (kg/m2) will be computed and BMI %ile and BMIz will be calculated from age and gender normative data. BMI %ile will determine weight status group. Change in BMI and BMIz are the best proxy measures for change in fat mass and standardized fat mass and will assess exploratory hypotheses. Change in BMI will serve as the primary outcome for the fully powered randomized controlled trial. For the current application, feasibility criteria will serve as the primary outcome. 0 months, 3 months, 12 months and 15 months
Secondary Measurement of endogenous circadian rhythms Circadian phase can be examined by measuring the circadian timing of melatonin onset under dim light conditions (dim light melatonin onset; DLMO). Compared to markers of endogenous circadian rhythms, melatonin is relatively robust. Salivary DLMO measures have demonstrated high intraclass correlations (.93) with plasma and sensitivity and specificity comparable to plasma assays. Following established procedures with children, salivary DLMO will be collected on a weekday evening in the laboratory under dim light conditions (<40 lux), via a cheek swab every hour beginning 5 hours prior to and ending 1 hour following typical bedtime. Saliva samples will be centrifuged, frozen, and assayed using radioimmunoassay test kits. DLMO phase will be determined using linear interpolation across the time points before and after melatonin concentration increased to and remained above 4pg/mL. 0 months, 3 months, 12 months and 15 months
Secondary Actigraphy for the measurement of sleep, sleep/wake patterns, physical activity, and light exposure. Actigraphs (GT3X-BT, Pensacola, FL) worn on the wrist of the dominant hand 24 hours a day for 7 days will measure sleep duration and timing of sleep onset and waking. Wrist placement reliably measures sleep duration in adolescents. Sleep diaries will be completed. Monitor-wear logs will identify times the accelerometer is removed and the activity engaged in while the monitor is off. The photocell contained in the Actigraph GT3X-BT will be used to measure ambient light exposure. Accelerometers have been extensively used to assess children's physical activity (PA). Five days of monitoring had 0.8 reliability of accurately capturing the habitual PA of children. Activity counts captured in 5-second epochs will be categorized into sedentary, light, moderate, and vigorous PA using established cut points. 0 months, 3 months, 12 months and 15 months
Secondary Body composition Since BMI can misrepresent adiposity among muscular and slender children, use of additional body fat indicators has been recommended. Investigators will assess percent body fat using Bod Pod. 0 months, 3 months, 12 months and 15 months
Secondary Dietary Assessment The Automated Self-Administered 24-Hour Dietary Assessment Tool (ASA-24)174 will be used to assess children's dietary intake (e.g., total daily caloric intake, timing of intake, timing of the last eating episode of the day). As recommended, parents will complete the adult version of the ASA-24, providing proxy report of their child's dietary intake. Investigators will use 3 days of diet assessment as 3 days optimize the prediction of doubly labeled water estimated energy expenditure. 0 months, 3 months, 12 months and 15 months
Secondary Parenting Structure Comprehensive General Parenting Questionnaire (CGPQ) is a parent report of parenting practices among parents of 5-13 year olds. Investigators will assess subscales related to parenting structure (inconsistent discipline, consistency, organization, and scaffolding). There is support for the construct validity of the CGPQ. Parenting structure subscales have demonstrated acceptable to good internal reliability (ranging from .67-.74). Subscale scores range from 5 to 25. Higher scores indicate higher levels of structure. 0 months, 3 months, 12 months and 15 months
Secondary Bedtime Routines The Bedtimes Routines Questionnaire (BRQ), is a 31-item parent report measure of children's bedtime routines, comprised of three scales measuring consistency of bedtime routines (weekday & weekend), reactivity to changes in bedtime routines, and frequency of adaptive and maladaptive activities. The BRQ scales had good internal consistency ranging from a = 0.69 to 0.90. Scores on the consistency and adaptive behavior subscales range from 10 to 50 with higher scores reflecting more consistent bedtime routines and higher. The reactivity scale scores range from 5 to 25 with higher scores reflecting greater reactivity. The maladaptive behavior scale has possible scores ranging from 6 to 30 with higher scores reflecting more maladaptive behaviors. 0 months, 3 months, 12 months and 15 months
Secondary Summer Care Arrangements How Children Spend their Summer (e.g., children's involvement in summer school, child care, entertainment programs, as well as day or overnight camps) will be assessed by a parent report survey based on a modified version of the Early Childhood Longitudinal Program Kindergarten Class' parent interview on summer activities. The Girl's Health Enrichment Multisite Studies demographic protocol will be employed with parents. 0 months, 3 months, 12 months and 15 months
Secondary Stress (Parent) Perceived Stress Scale (PSS-10) is a 10-item self-report measure of perceived stress with established acceptable psychometric properties(a's >.70, test-retest criterion coefficient >.7, validated factor structure and evidence of convergent validity). Scores range from 0 to 40 with higher scores reflecting higher levels of perceived stress. 0 months, 3 months, 12 months and 15 months
Secondary Social Support (Parent) Interpersonal Support Evaluation List (ISEL) is a 12-item self-report measure of the perceived availability of social support (i.e. Tangible, appraisal, and belonging). The ISEL has demonstrated good reliability. The "tangible" subscale assesses perceived availability of resources and material aid; the "appraisal" subscale assesses the perceived availability of another individual(s) to discuss one's problems; the "self-esteem" subscale assesses the perceived availability of someone to compare one's self to in a positive manner; and the "belonging" subscale, the perceived availability of having others to socialize and do things with. Scores range from 0-30 on each scale with greater scores indicating higher levels of social support. 0 months, 3 months, 12 months and 15 months
Secondary Motivation to Continue in the Program The Treatment Questionnaire Concerning Continued Program Participation was originally developed to assess reasons for continuing to participate in a weight-loss program. We have adapted it assess reasons for continuing to participate focused on addressing children's sleep during summer. Scores in the Autonomous Regulation scale range from 5 to 35 and scores on the Controlled Regulation range from 8 to 56. Higher scores reflect higher levels of Autonomous and Controlled regulation. 3 months
