Participants
This study was a mixed method, parallel, pilot randomized controlled trial (RCT) aiming to examine the feasibility and effectiveness of DLT among women with young children aged under 6 years. Participants’ inclusion criteria were as follows: women who 1) had at least one child under 6 years; 2) had no acute mental health crisis that needed emergency intervention and had not taken psychotropic medications within the past 3 months; 3) could use Zoom at home; and 4) faced difficulties while caring for their children at home during the pandemic. To recruit the participants, web-flyers advertising this study were uploaded on online platforms, including the researchers’ social network services and boards of regional community networks.Each group had approximately 10 to 11 participants. This number was not optimized for between-group comparisons, as achieving 80% power (effect size = .5, α = .05) to detect differences between two independent groups requires a minimum sample size of 51 per group. However, because of the logistical challenges in managing larger groups in a Zoom-based intervention and considering the importance of participant interaction within our program, we opted for a smaller sample size. Eventually, 22 participants were recruited. Participants voluntarily provided written informed consent via email; thereafter, the online baseline survey was conducted.
