aCategories with different number of asterisks (*, **) within a column are significantly different (P<.05) based on our analytical approach, which included Kruskal-Wallis one-way ANOVA at the variable level, followed by Mann-Whitney U tests.
bNot including mindfulness/meditation.
cDue to the small number of included apps, brackets in this cell reflect the range (minimum-maximum value) and not the IQR.
dDue to the small number of included apps, IQR or range could not be calculated (marked with N/A).
eN/A: not applicable.
fIncludes two apps that use a chatbot (Wysa, Woebot), which did not have a different pattern of results emerging for a certain direction.
