In “Culturally Adapted Guided Internet-Based Cognitive Behavioral Therapy for Hong Kong People With Depressive Symptoms: Randomized Controlled Trial”[1], the authors noted some errors.

One sentence has been changed. In the “Measurements” section, the third sentence in the third paragraph originally appeared as follows:

Item scores were summed for the positive and negative subscales, with higher total scores indicating more positive and negative automatic thoughts, respectively.

This sentence now reads:

Item scores were averaged for the positive and negative subscales, with higher total scores indicating more positive and negative automatic thoughts, respectively.

The originally published Tables 2 and 4 have been revised due to typos. The new Table 2 and Table 4 that are replacing the original published versions are shown below (with changes marked in italics).
