Other information about tool (e.g., additional psychometrics [NPV, PPV, Youden’s index, diagnostic odds ratio]) A 20 item scale was developed by local Thai clinicians after a literature review. It was translated and adapted by the expert team and then piloted in an initial set of 20 depressed Thai psychiatric patients. Their feedback was integrated to produce the final 20 item scale.

Factor analysis suggested a five-factor structure explaining the majority of the variance.

The Pearson correlation with the Hamilton Rating Scale for Depression was 0.7188 (p<0.0001), Comparison with the HRSD suggested a Thai Depression Inventory cutoff score of 34 as suggestive of major depression.
