The Wakefield self-assessment depression inventory demonstrated a strong correlation (+0.87) with the Hamilton Rating Scale, misclassifying 3% of patients and 7.5% of normals at a 14-15 point cut-off.
Observational
Effect estimate: Correlation +0.87
SUMMARY A self-assessment inventory for measuring severity of depressive illness is described, Its chief merits are brevity and simplicity. The correlation with the Hamilton Rating Scale is +0·87. At a cut-off level of 14–15 points 3% of patients and 7·5% of ‘Normals’ are misclassified. The mean scores for male and female patients do not differ significantly and the small positive correlation of score with age is of little practical significance. The limitations in this inventory are discussed but, despite them, it has practical value and merits further development.
Snaith et al. (Mon,) conducted a observational in Primary depressive illness. Wakefield self-assessment depression inventory vs. Hamilton Rating Scale was evaluated on Correlation with the Hamilton Rating Scale (Correlation +0.87). The Wakefield self-assessment depression inventory demonstrated a strong correlation (+0.87) with the Hamilton Rating Scale, misclassifying 3% of patients and 7.5% of normals at a 14-15 point cut-off.
