Admission to the pediatric intensive care unit (PICU) is well-recognized to be extremely distressing and stressful for the patient and family. As medical research and technology have advanced more and more children in the PICU are surviving, however in turn incurring new and persistent impairments across physical, cognitive, emotional, and social domains of health. This phenomenon is often referred to as post-intensive care syndrome (PICS). These impairments not only impact the patient but parents have also been found to have poor emotional health outcomes following discharge from the PICU.

Consistently, parents/caregivers of children admitted to the PICU report their primary concerns to be 1) the overwhelming physical environment of the PICU, 2) uncertainty about the child's survivorship and outcomes, 3) relationships and communication with staff, and 4) feeling helpless. Additionally, research has shown that caregiver-perceived stress during the child's hospitalization positively predicts post-traumatic stress three months after discharge for parents/caregivers (Nelson et al., 2019), which may translate into higher risk and duration of post-traumatic stress in their children. Therefore, providing an in-hospital outlet such as a "PICU Journal" for patients and families to express their subjective experiences may help bridge the gap between perception and reality as a means of buffering against post-traumatic responses. Conceptually, a semi-structured journal intervention may integrate the therapeutic aspects of journaling while also providing pertinent information and serving as an advocacy and communication tool. Prior research has demonstrated the use of a "PICU Journal" is feasible for implementation and has been well-received by families of children in the PICU (Herrup et al., 2019).

Therefore, the aims of this mixed-method study are to 1) examine the relationship between this journaling intervention and the perceived stress, care engagement, symptoms of anxiety, and depression, and the development of PICS in parents of children hospitalized in the PICU, and 2) examine the relationship between parent participation in this intervention and the development of PICS-p in children, and 3) assess the feasibility of this intervention from key stakeholders.

Eligible participants will be identified by their primary Certified Child Life Specialist (CCLS) using the daily PICU census and electronic medical record. All eligible participants will first be approached by the child life specialist on their care team to provide brief information about the study and refer to the key study personnel (KSP) if the parent/caregiver is interested in learning more. If they are potentially interested in participating, a member of the KSP (comprised of a doctoral level CCLS, psychology graduate students, PICU physician, and research nurses) will approach the parent/caregiver at bedside and give information and obtain consent. When approaching for consent, the KSP will first obtain approval to approach from the patient's bedside nurse to ensure it is a feasible and appropriate time to do so. All parents/caregivers who indicate interest will be approached to participate to ensure a diverse and broad sample, until a total of 75 parents/caregivers have completed participation in the study. No randomization will be used.

Once consent has been given by the parent/caregiver (using an electronic consent form housed in REDCap), they will complete a short demographic survey in REDCap. The family will then be given the PICU Journal along with supplies and instructions on how to access additional pages and the photo printer. The PICU Journal was developed by conducting extensive research on perceived stressors in the PICU, post-intensive care syndrome in pediatrics and their families, and the use of dairies in the intensive care unit setting, along with consultation from Certified Child Life Specialists, and with input from family advisors. Families will be able to take the original journal home with them.

Data will be collected at three-time points: time one (T1) between 24 and 72 hours of the child's admission, time two (T2), peri-discharge, and time three (T3) three months post-discharge.

Timepoint 1 (T1) Between 24 - 72 hours after admission:

Parent Participation Consent Form Illness Severity (Chart Review) Child Demographics (Chart Review) Parent Demographics Survey Abbreviated Parental Stressor Scale: Pediatric Intensive Care Unit (APSS: PICU) Caregiving Health Engagement Scale (CHE-s)

Timepoint 2 (T2) Peri-discharge Abbreviated Parental Stressor Scale: Pediatric Intensive Care Unit (A-PSS: PICU) Caregiving Health Engagement Scale (CHE-s) Hospital Anxiety and Depression Scale (HADS) Journal Use & Satisfaction Survey

Timepoint 3 (T3) 3 months post-discharge:

Hospital Anxiety and Depression Scale (HADS) Impact of Events Scale-Revised (IES-R) At Home Journal Use & Satisfaction Survey Child Participation Assent Form (Child Report) Child Revised Impact of Events Scale (CRIES-8) (Child Report)

*Semi-Structured Interview (Parents)
