In “Key Variables for Effective eHealth Designs for Individuals With and Without Mental Health Disorders: 2^12-4 Fractional Factorial Experiment” (J Med Internet Res 2021;23(3):e23137), two display errors were noted.

  • In Table 1, row “Screen length,” column “Levels of dimensions in the factorial design; High,” the character “>” was not rendered in the originally published version. The value “1” has been corrected to “>1”.
  • In Table 1, row “Constant navigational toolbar,” column “Levels of dimensions in the factorial design; High,” the value was not rendered in the originally published version. This value has been corrected to “1”.

In addition, five corrections have been made to the wording in Table 6:

  • In row "The best performing websites had these design elements," "Mental illness other than SSD;" column "Design elements;" the phrase "screen per page length ≤1" has been corrected to "page length ≤1 screen long."
  • In row "The best performing websites had these design elements," "No mental illness;" column "Design elements;" the phrase "screen per page length ≤1" has been corrected to "page length ≤1 screen long."
  • In row "The worst performing websites with low navigational depth (≤3 levels) had these design elements," "Mental illness other than SSD;" column "Design elements;" the phrase "Screen per page length >1" has been corrected to "Page length >1 screen long."
  • In row "Variables that, when present, always had a positive effect on performance," the subrow "Screen per page length ≤1" has been corrected to "Page length ≤1 screen long."
  • In row "Variables that, when present, always had a negative effect on performance," the subrow "Screen length >1 screen long" has been corrected to "Page length >1 screen long."

The correction will appear in the online version of the paper on the JMIR Publications website on July 7, 2021, together with the publication of this correction notice. Because this was made after submission to PubMed, PubMed Central, and other full-text repositories, the corrected article has also been resubmitted to those repositories.
