Summarize PTSD scores and diagnoses

Source: R/scoring_and_diagnosis.R
summarize_ptsd.Rd

Creates a summary of PCL-5 total scores and PTSD diagnoses, including mean total score, standard deviation, and number of positive diagnoses.

Usage

summarize_ptsd(data)

Arguments

data

A dataframe containing at minimum:

  • A 'total' column with PCL-5 total scores (from calculate_ptsd_total)

  • A 'PTSD_Diagnosis' column with TRUE/FALSE values (from determine_ptsd_diagnosis)

Value

A dataframe with one row containing:

  • mean_total: Mean PCL-5 total score

  • sd_total: Standard deviation of PCL-5 total scores

  • n_diagnosed: Number of positive PTSD diagnoses

Details

This function calculates key summary statistics for PCL-5 data:

  • Mean total score (severity indicator)

  • Standard deviation of total scores (variability in severity)

  • Count of positive PTSD diagnoses (prevalence in the sample)

Examples

# Create sample data
sample_data <- data.frame(
  total = sample(0:80, 100, replace = TRUE),
  PTSD_Diagnosis = sample(c(TRUE, FALSE), 100, replace = TRUE)
)

# Generate summary statistics
summary_stats <- summarize_ptsd(sample_data)
print(summary_stats)
#>   mean_total sd_total n_diagnosed
#> 1      40.83 21.92322          58
