The Development and Evaluation of iCF-PWR for Healthy Siblings of Individuals With Cystic Fibrosis

Study Overview
=================
Brief Summary
-----------------
The goal of the clinical trial is to test whether a mental health program that is delivered through the Internet works well for healthy children and adolescents with siblings with cystic fibrosis (CF). The main questions it aims to answer are: Does the program improve the mental health and quality of life of healthy siblings? Does the program improve the relationship between healthy children and adolescents and their sibling with CF? Does the program help healthy siblings learn about CF? Participants will: Fill out an online survey asking questions about their family and mental health before the program Complete the online mental health program over five weeks Fill out a weekly question asking about their mood for 10 weeks Fill out an online survey asking questions about their family and mental health after the program Healthy children and adolescents with siblings with CF will be compared against themselves. Researchers will compare participants scores before starting the program with their scores during and after completing the program. Researchers hope to develop a program that improves mental health, quality of life, sibling relationships, and knowledge about CF.

Detailed Description
-----------------
BACKGROUND: Healthy siblings of individuals with chronic illnesses, such as with cystic fibrosis (CF), have been shown to experience elevated psychological symptoms (e.g., depression, anxiety), negative psychological adjustment, and internalizing behaviours. Psychoeducation, sibling-oriented care, and involvement in siblings' treatments have demonstrated positive outcomes for siblings in terms of psychological wellbeing, social support, and quality of life. At present, there are currently no tailored mental health programs for healthy siblings of individuals with CF. Despite these advances, there is currently no specific mental health program designed for healthy siblings of individuals with CF in Canada. One viable and appealing option for the delivery of mental health services that would eliminate several of the barriers encountered in face-to-face methods of service delivery (e.g., travel to access care, financial restrictions) is through the Internet. Support exists for the effectiveness and efficacy of Internet-delivered psychological treatments for healthy children and children with a range of acute and chronic health conditions. As such, an Internet-delivered method of mental health service delivery designed to target the specific needs of healthy siblings of individuals with CF may be beneficial. The overall goal of the project is to evaluate a recently developed evidence-based, Internet-delivered mental health prevention program for families with CF [called the Internet-Delivered Cystic Fibrosis Mental Health Prevention, Wellness, and Resource program (iCF-PWR)] living in Saskatchewan, that may be helpful in improving mental health and quality of life. PARTICIPANTS: Six children (aged 8 to 12 years) with CF will be recruited from CF clinics and CF chapters in Canada. Research ethics approval has been approved in those respective health care institutions. METHODS/PROCEDURES: Preliminary parent consent will be obtained over the phone. A web link (using Qualtrics) to an informed consent/assent form, demographics form, and questionnaires (i.e., measures of CF health, anxiety, depression, health anxiety, anxiety sensitivity, intolerance of uncertainty, quality of life, disease knowledge, and perception of their sibling relationship) will be e-mailed to parent caregiver. The parent caregiver will help facilitate the child's completion of questionnaires online using Qualtrics, a web-based survey software that enables a user-friendly model of conducting surveys. Parents will also complete two questionnaires about the healthy sibling's anxiety, and depression symptoms. Completion of the questionnaires will take approximately one hour. These measures will be completed again upon completion of the program. A link to the post-program questionnaires will be provided via email to parent caregivers to be completed after the program has been completed by the child. Child participants will be also asked to complete a series of one-item ratings of mood and anxiety prior to beginning the program (i.e., phase A) and during completion of the program (i.e., phase B) using Qualtrics. Each phase of the study will be approximately five weeks in length. Once enrolled, parent caregivers will be provided with a username/password. Participants will be instructed to keep their username/password private. A contact e-mail of the research coordinator will be provided for technical support and instructions on how to operate the site. All contact with participants will be via e-mail, although a telephone number for the research coordinator will also be provided. Supervision of contact with child participants and parent caregivers will be provided by the research supervisor (i.e., Dr. Kristi Wright). Informatics of participant use of the program will be collected (e.g., amount of time spent completing each module, program completion time). Participants will be encouraged to complete one module per week. A reminder e-mail will be sent to parents if their child has not logged onto the program at least once per week. Participants will also be sent email reminders on the days they have been scheduled to complete a rating of mood and anxiety. ANALYSES: Statistical analyses will be performed using IBM SPSS Statistics-Version 25. Visual analyses are the primary analyses used to determine whether there may be a functional (i.e., three demonstrations of the effectiveness of the intervention effect) or causal relationship between the intervention and the outcome variables. Visual analysis refers to reaching a judgment about the reliability or consistency of an intervention's effects by visually examining the graphed data. The program's effectiveness will be evaluated primarily by examining the changes between baseline (phase A) and post-program (phase B) measures, in addition to changes across the repeated momentary mood and anxiety measure. Baseline and post-program measures and the mood and anxiety ratings will be presented graphically to enable visual inspection. The visual inspection of data will also include analyzing trends in change over time and changes in variability of outcome measures. If the data suggests a functional or causal relationship may be present, the visual analyses will be supplement with a quantitative analysis method evaluating the magnitude of the intervention effect. Descriptive statistics will be computed for total scores from the outcome measures. Healthy siblings' baseline and post-program total scores from the measure of interest will also be compared to existing community and/or normative data. A series of independent sample t-tests will be computed to compare healthy siblings to similar aged children to assess for potential differences across samples. To evaluate the magnitude of change in outcomes measures from baseline and post-program, a Reliable Change Index (RCI) will be calculated as an indicator of clinically significant change. The RCI will be calculated for each participant by taking their pre-test and post-test total scores and dividing it by the standard error of the difference.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: iCF-PWR Intervention<br>Internet-delivered Cystic Fibrosis Mental Health Prevention, Wellness, and Resource (iCF-PWR) program is comprised of five text/voice-delivered, animated, interactive modules. The pathways are comprised of the same modules that take approximately 15 to 20 minutes to complete. Modules are comprised of web pages and/or screens with numerous illustrations and interactive components. Written module content will be presented verbally as well as in text format. The program modules include: (1) What is CF? (i.e., physiological explanation of CF, prevalence rate); (2) How does my sibling with CF stay healthy? (i.e., review of medication, nutrition, physiotherapy treatment, and why treatment is important); (3) How does CF affect me?; (4) Mental health awareness (i.e., introduction to cognitive behaviour model of emotions-thoughts, feelings, bodily sensations, and behaviours); and (5) Strategies (i.e., ways to challenge unhelpful thoughts, talking about emotions, relaxation). | Behavioral: Internet-delivered Cystic Fibrosis Mental Health Prevention, Wellness, and Resource (iCF-PWR) program<br>* The iCF-PWR program is a self-guided mental health prevention program designed for families with CF.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Mood and Anxiety Rating | Single ratings of self-reported mood and anxiety will be completed ten times over the course of the study. One question will assess mood and one question will assess anxiety using a 3-point Likert scale (0 = none of the time; 1 = some of the time; 2 = a lot of the time) to indicate the frequency of the symptom that day. Ratings will be completed prior to beginning the program (baseline - phase A) and during completion of the program (intervention - phase B). The number of ratings in each phase will vary based on the participant and be distributed equally across the 5-week periods with a minimum of three ratings per phase (i.e., during baseline or intervention). | 10 Weeks | 
| Change from Baseline in the State-Trait Anxiety Inventory for Children (STAI-C) | The STAI-C measures general anxiety in children on a continuous scale with items being rated on a 3-point Likert scale reflecting the frequency of anxiety symptom. Total scores can range from a minimum score of 20 to a maximum score of 60. | Baseline and Week 10 (post-intervention) | 
| Change from Baseline in the Children's Depression Inventory-2 (CDI-2) | The CDI-2 measures cognitive, affective, and behavioural symptoms of depression in children and adolescents on a continuous scale. Each item is rated on a 3-point Likert scale ranging from 0 (absence of symptom) to 2 (definite symptom). Total raw scores are converted into T-scores with a score of 65 being indicative clinically significant depressive symptoms. | Baseline and Week 10 (post-intervention) | 
| Change from Baseline in the Childhood Illness Attitudes Scale (CIAS) | the CIAS assesses fears, beliefs, and attitudes that are associated with health anxiety and abnormal illness behaviour in school children on a continuous scale. Items are rated on a 3-point Likert scale with total scores range from 29 to 87 with higher scores reflecting higher levels of health anxiety associated behaviours. | Baseline and Week 10 (post-intervention) | 
| Change from Baseline in the Childhood Anxiety Sensitivity Index (CASI) | The CASI measures fear of anxiety-related symptoms in school children on a continuous scale. Each item is rated on a 3-point Likert scale (1 = none; 2 = some; 3 = a lot) with total scores ranging from 18 to 54 and higher scores reflecting higher levels of anxiety sensitivity. | Baseline and Week 10 (post-intervention) | 
| Change from Baseline in the Intolerance of Uncertainty Scale-Revised (IUS-R) | The IUS-R measures intolerance of uncertainty in children on a continuous scale. Items are rated on a 5-point Likert scale ranging from 1 (not at all like me) to 5 (entirely like me). Total scores range from 12 to 60 with higher scores indicating higher levels of IU. | Baseline and Week 10 (post-intervention) | 
| Change from Baseline in the Pediatric Quality of Life Inventory (PedsQL-4.0) | The PedsQL-4.0 measures health-related quality of life in healthy and acute and chronically ill children and adolescents on a continuous scale. Items are rated on a 5-point Likert scale ranging from 0 (never) to 4 (almost always). The PedsQL-4.0 is comprised of four generic core scales that encompass physical functioning, emotional functioning, social functioning, and school functioning. | Baseline and Week 10 (post-intervention) | 
| Change from Baseline in the Sibling Relationship Questionnaire-Revised (SRQ-R) | The SRQ-Rdesigned to assess children's perceptions of their siblings in areas of Closeness/Intimacy, Power, Conflict, and Rivalry. On a 5-point Likert scale ranging from 1 (hardly at all) to 5 (extremely much) children are asked to rate how well a characteristic describes their relationship with their sibling. Higher scores on each of the scales and factors indicate greater levels of the specified relationship quality in the sibling relationship. | Baseline and Week 10 (post-intervention) | 
| Change from Baseline in the Disease Knowledge Questionnaire | The measure was constructed to assess CF disease knowledge as it related to the iCF-PWR content. It is comprised of 13 items rated on a 7-point Likert scale (1 = strongly disagree to 7 = strongly agree). Higher scores indicate greater CF disease knowledge. | Baseline and Week 10 (post-intervention) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from Baseline in the Children's Depression Inventory-2 - Parent Report (CDI-2 P) | The CDI-2 P assesses a parent's observation of their child's or adolescent's cognitive, affective, and behavioural symptoms of depression. Each item is rated on a 4-point Likert scale ranging from 0 (not at all) to 2 (much or most of the time). Total raw scores are converted into T-scores with a score of 65 being indicative clinically significant depressive symptoms. | Baseline and Week 10 (post-intervention) | 
| Change from Baseline in the State-Trait Anxiety Inventory - Parent Version (STAI-P) | The STAI-P assesses state anxiety (i.e., at this present moment) in school children with and without physical symptoms. Items are rated on a 4-point Likert scale reflecting the frequency the anxiety symptom occurs (1 = not at all; 2 = sometimes; 3 = moderately; 4 = very much so). Total scores for the subscales can range from a minimum score of 20 to a maximum score of 80. | Baseline and Week 10 (post-intervention) |
