In “The Impact of Parental Support on Adherence to Therapist-Assisted Internet-Delivered Acceptance and Commitment Therapy in Primary Care for Adolescents With Anxiety: Naturalistic 12-Month Follow-Up Study” (JMIR Pediatr Parent 2025;8:e59489), the data in Table 2 was incorrectly presented.
The corrected version of is as follows:
| Completed modules or sessions (%) | (iACT) without parental support (n=9), n (%) | (iACT) with parental support (n=15), n (%) |
| <25 | 1 (11) | 0 (0) |
| 25-50 | 2 (22) | 0 (0) |
| 50-75 | 1 (11) | 1 (7) |
| 75-100 | 3 (33) | 12 (80) |
| Missing | 2 (22) | 2 (13) |
In the originally published article, the Methods section did not include information on how missing data were handled in the survival (Kaplan-Meier) analysis.
To address this, the following sentence has been added to the Methods section under “Data Analysis” on page 18:
“Participants with missing time-to-event data were excluded from the Kaplan-Meier analysis”.
The corrected version of that excerpt now reads:
Due to a nonrandomized design, a small sample, a large dropout, and the fact that no a priori power analysis was made, the data are nonparametric, which makes between-group comparisons less meaningful. Therefore, the TAU group (n=11) is not included in this evaluation. Adherence was analyzed using descriptive data and Meier-Kaplan survival analysis, a statistical method used for measuring the distribution of time of occurrences in cohort groups []. In this study, dropout is defined as terminating the iACT program before the last module. Participants with missing time-to-event data were excluded from the Kaplan-Meier analysis. Meanwhile, the outcome measures were analyzed using within-group comparisons.
has been updated to improve clarity and ensure accurate representation of the Kaplan-Meier survival analysis. The revised figure reflects the exclusion of participants with missing time-to-event data, aligning it with the updated Methods section. No changes were made to the underlying data or results.
