CPP Cohort 1
The Young Child PTSD Checklist (YCPC)* is a screening questionnaire used to assess caregiver-reported symptoms of post-traumatic stress disorder among young children (ages 1-6 years old). Domains assessed include DSM 5 PTSD symptom categories B-D for children 6 years old or younger (i.e., re-experiencing, avoidance or negative alterations in cognition, and alterations in arousal and reactivity) and functional impairment. Mean scores of these domains will be examined from pre- to post-treatment, as well as total severity of PTSD symptoms and functional impairment.
Descriptive Statistics: Pre- and post-treatment assessment measure means, standard deviations, and standard errors for each subscale of the YCPC are listed in the table below, as well as the range of possible scores and clinically significant range for each subscale.
YCPC Subscales: Descriptive Statistics
Repeated Measures Analyses: Paired t-tests were run on the YCPC to examine pre-post treatment differences on each of the subscales, the Overall Diagnosis Level, and Functional Impairment scores. Analyses showed statistically significant improvement in all scales: intrusion symptoms, avoidance or negative alterations in cognition and mood, alterations in arousal and reactivity, overall diagnosis level, and functional impairment. Please see the table and graph below for more information on these analyses.
YCPC Subscales: Paired Sample t-tests
YCPC Subscales: Pre-Post Treatment Mean Scores
YCPC Overall: Pre-Post Treatment Mean Scores
Individual Clinically-Significant Change:
At pre-treatment, 9 clients had YCPC Overall Diagnosis Level scores at or above the clinical cut-off score of 26. No clients were missing post-treatment data for this scale. Analysis showed that the YCPC Overall Diagnosis Level score for 9 of these 9 clients (100%) decreased to non-clinically significant levels by post-treatment. At pre-treatment, 29 clients had YCPC Functional Impairment scores at or above the clinical cut-off score of 4. No clients were missing post-treatment data for this scale. Analysis showed that the YCPC Functional Impairment score for 21 of these 29 clients (72%) decreased to non-clinically significant levels by post-treatment. Clinical significance was not able to be determined for the subscales of Intrusion Symptoms, Avoidance or Negative Alterations in Cognition and Mood, and Alterations in Arousal and Reactivity, because clinical cut-offs do not exist for these subscales.
