Participants answered questions relating to each module's mechanism of change on a 7-point Likert Scale, from "strongly disagree" to "strongly agree".

2 questions related to their ability to cope with stressors over the upcoming weeks (including challenges relating to COVID-19). Participants answered these questions on a 7-point Likert Scale, from "strongly disagree" to "strongly agree". Specifically, we asked participants:

if they will be able to handle lifestyle changes due to the coronavirus, if the pandemic will have an extremely negative impact on their life.

We asked participants three items to assess secondary control (Weisz et al., 2010). The items are scored on a 4-point Likert scale, ranging from 0 ("Very false") to 3 ("Very true").

The three items are:

When something bad happens, I can find a way to think about it that makes me feel better.

After a really hard day, I can make myself feel better by remembering some good things that happened.

When bad things happen to me that I can't control, there are lots of things I can do to feel better.

Higher scores indicate greater secondary control.
