Data for manuscript 'Validating an Intervention for Imposter Syndrome Using Schema Change'

Data collected for pilot study of an intervention for imposter syndrome using schema change, showing significant improvement.
Data is for 31 participants on one-to-one intervention recording their top scoring (most severe) imposter syndrome symptoms on a scale of 1 to 10 (10 is most severe).
Self-scored symptoms were taken before and after the intervention, and average improvements are calculated.
The average improvement and standard deviation are calculated. Standard deviation of improvement is taken for the whole sample (31), because the number of datapoints for each individual symptom of imposter syndrome is not high enough for statistical relevance of standard deviation. e.g. sample size of 4.
