In “Culturally Adapted Guided Internet-Based Cognitive Behavioral Therapy for Hong Kong People With Depressive Symptoms: Randomized Controlled Trial”[], 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 and that are replacing the original published versions are shown below (with changes marked in italics).
