Staff at NPIS (Cardiff) also contribute to the TOXBASE database, which contains more than 17,000 product entries.
NPIS (Cardiff) also leads on the UK Poisons Information Database which has enabled the identification of trends in poisoning, leading to public health improvements on everything from liquid detergent sachets to novel psychiatric substances.
The NPIS helpline is not open to the public, but is specifically targeted at health professionals.
Based on analyses and results from Study 1, the following modifications were made to the NPIS subscales.
We computed Pearson product-moment correlations between test and retest scores in addition to intraclass correlations (ICC; 1-way random model, single measures) to assess the test-retest reliability of the NPIS subscales.
We performed a PCA (varimax rotation) on the NPIS version 2 (NPIS 2) data, largely replicating the factor structure identified in NPIS version 1 (NPIS 1).
