After publication of the original article [1], it came to the authors’ attention that there were typing errors in the data presented in Tables 2 and 4. The values in the EQ-5D index column for both tables were mistyped, and the correct versions (Tables 2 and 4) of both tables are published in this erratum.

aSignificantly different between pre- and post-CBT periods

In addition, there were errors in the EQ‑5D and QALYs sub-section of the Results.

In the second paragraph, the following sentence has been amended to change the post-CBT value from 0.199 to 0.189: “The mean changes in the EQ-5D index from baseline were 0.143 at mid-CBT and 0.189 at post-CBT.”

In the same paragraph, the final sentence has been amended to correct the change in QALYs from 0.178 to 0.167: “Under the best conditions—namely, that EQ-5D maintained a high level at 12 months—the change in QALYs from baseline was estimated as 0.167 QALYs. Therefore, between 0.102 and 0.167 QALYs were gained per 1 year.”

Finally, in the last paragraph of the sub-section, the JPY and US$ values have been corrected: “Using these values to convert the change in QALYs per 1 year into WTP values, we obtained values of JPY 510,000–835,000 (Japan) and US$ 6320–10,350 (United States). Because we provided patients 16 sessions of CBT, we estimated that patients would spend JPY 31,800–52,100 (Japan) and US$ 395–647 (US) per one session (50 min) of CBT.”
