Data Products
All data products made available through the TX-CTRN portal login are participant records which have been filtered to remove personally identifying and health information (PII/PHI). Data is further deidentified through the following methods and transformations:
- Date of birth and dates of service are removed and replaced by “age at the date of the visit” calculated in months. These calculations are consistent with requirements for data publication through the National Institute of Health’s National Data Archive (NIH NDA),
- Data associated with location have been removed or aggregated into groups large enough to maintain individual anonymity. For example, ZIP codes may be truncated or removed entirely based on the number of individuals represented.
- Identifying demographics and fields with sparse data are removed or aggregated
Survey Instruments (Descriptions of Psychosocial Data Collected)
Acute Stress Checklist for Children (ASCKids): This 29-item scale assesses symptoms of Acute Stress Disorder in the child at the baseline visit. It is administered to children who have experienced a traumatic event fulfilling DSM-5 PTSD Criterion A during the month prior to the Baseline Visit.
Clinician-Administered PTSD Scale for DSM-5 Child/Adolescent Version (CAPSCA): Pynoos et al., 2015. The CAPSCA is a 30-item clinician-administered PTSD scale based upon DSM-5 criteria for children and adolescents ages 7 and above. It is a modified version of the CAPS-5 that includes age-appropriate items and picture response options. The CAPSCA assesses the 20 DSM-5 PTSD symptoms. For each symptom, standardized questions and probes are provided. In addition, questions target the onset and duration of symptoms, subjective distress, impact of symptoms on social functioning, impairment in development, overall response validity, overall PTSD severity, improvement in symptoms since a previous CAPS administration, and specifications for the dissociative subtype (depersonalization and derealization). It is administered in an interview format to all subjects with both child and parent present at every visit.
Child and Adolescent Social Support Scale (CASSS): This 60-item scale is administered to the child at each visit to assess perceived social support. It is administered as an interview to 8-11 year old children and a self-report scale to subjects 12 and older who have not yet completed high school. For 18-20 year old participants who have graduated high school, the CASSS College Version is used.
Connor-Davidson Resilience Scale (CDRISC): The CD-RISC is a 10-item measure of resilience, or adaptability, in youth. The briefer, 10-item version was determined to have strong psychometric properties in a community sample of adult participants (Campbell-Sills et al., 2009) and was originally validated in three samples of college undergraduate students (Campbell-Sills & Stein, 2007). It is administered to the child at the Baseline Visit.
Concise Health Risk Tracking Scale (CHRT16): Clinician-Rated CHRT-Behavioral Module; Trivedi et al., 2011. The self-report CHRT is a 16-item scale that evaluates specific thoughts about suicide and thoughts and feelings associated with an increased risk for suicide (Trivedi et al., 2011). Its psychometric properties have been well-established in children and adolescents (Mayes et al., 2018, 2020). The companion behavioral module is a clinician-rated assessment to gather lifetime and since last visit information among specific thoughts and behaviors, including suicidal ideation and attempts, non-suicidal self-injury, preparatory acts, completed suicides, and accidental injuries.
CRAFFT+N: This 10-item scale is administered to the child/adolescent at each visit to identify patterns and psychosocial consequences of substance abuse. It is administered in an interview format to all subjects. The parent is not present when the CRAFFT+N is administered.
Inventory of Parent and Peer Attachment–Revised (IPPA-R): This is a 28-item scale administered at baseline and each followip visit as as an interview to 8-11 year old children and as a self-report scale to subjects 12 and older. The scale is used to assess various dimensions of attachment, such as trust, communication, and emotional support, within the parent relationship.
Mini-International Neuropsychiatric Interview for Children and Adolescents (MINI-KID): Sheehan et al., 2010. The MINI-KID is a structured diagnostic interview for DSM-V psychiatric disorders in children and adolescents. Also includes an accompanying parent version to achieve a best estimate rating of diagnoses. Psychometrics among children and adolescents have been established. For this study, the MINI-KID will be utilized for participants aged 18-20. The assessment is administered to the child/adolescent at every visit. Per guidelines recommended by the originator of the scale (David Sheehan), the interview is administered in its entirety with both parent and child present. The interviewer then meets separately with the parent to review the responses provided by the child. Finally, the interviewer meets separately with the child for any additional corrections, particularly focusing on the substance abuse and suicidality questions that children may be most reluctant to answer truthfully when a parent is present.
Outside School Social Media Behavior (OSSMB) Scale: This is a 21-item scale administered at baseline and each follow-up visit as an interview to 8-11 year old children and as a self-report scale to subjects 12 and older administered at each visit to identify patterns of social media use.
Personal & Family History Questionnaire (PFH): This questionnaire collects demographic data (e.g., age, sex, family composition, ethnicity, etc.) for the child and family, the child’s psychiatric and medical history, and the family psychiatric history. The child completes the ‘Child History’ section of the PFH, and the parent completes the “Family History” section. The “Child Treatment” section is completed by the parent and child together with the research interviewer.
Patient Health Questionnaire-A (PHQA): The PHQA is a nine-item self-report inventory that assesses for symptoms in all nine symptom domains of a major depressive episode. It is the PHQ-9 modified for adolescents 11-18 years. (Johnson et al., 2002). This scale is administered to the child at every visit. It is administered as an interview to 8-11 year old children and as a self-report scale to subjects aged 12 and older.
Screen for Child Anxiety Related Disorders (SCARED-C) Child Version: The SCARED is a 41-item inventory to screen for signs of anxiety disorders in children, with versions to be completed by both children and parents. Psychometric properties in youth samples have been described (Birmaher et al., 1999).
Traumatic Events Screening Inventory - Child (TESIC): The TESIC is a 25-item clinician-administered interview that assesses a child’s experience of potential traumatic events, including current and previous injuries, hospitalizations, domestic violence, community violence, disasters, accidents, physical abuse, and sexual abuse. The TESIC is for use with individuals aged 6-18. It is administered at the Baseline Visit to identify lifetime traumatic experiences. It is re-administered at the 6-Month and 12-Month Visits to identify additional traumatic experiences that may have occurred in the interval between study visits. The parent is not present when the TESIC is administered.
Traumatic Events Screening Inventory - Parent (TESIP): This 25-item self-report scale is completed by the parent at the start of the Baseline Visit to provide data regarding traumatic events experienced by the child. It is reviewed by the rater to ensure consistency as (s)he administers the TESIC to the child.
