Themes and design implications from the design workshops.

Key themes and subthemes		Quotes	Design implications
1. Content and information provided
	Practical and easy to use in everyday life	I'd probably more likely engage with mindfulness self-care or distress management, maybe breathing as well. [Advisor #1]	Include simple, time-effective activities that can provide immediate benefits in mental health.
	Uplifting and motivational	… self-care and self-value, self-worth, belief is something that I just constantly need drilled into me [Advisor #2]	Include information that encourages and inspires.
		I really appreciated some of the messages behind the posts…I feel like they would be really uplifting and inspiring, which I think is what we're going for here, which is great...definitely somewhere between corny and inspirational. [Advisor #3]	Avoid clichéd, idealistic phrases.
	Emotionally validating	It doesn't even have to necessarily talk about how it (suicidal thoughts) works biologically, but just some info regarding... Even just statistics, the reminder that it is normal to experience these things occasionally. Just a little bit about how many people have it, or ways to cope … any sort of message, whichever way it's put, really needs to have that backing of validation. [Advisor #1]	Information should resonate with the feelings that users may be experiencing. Avoid presenting facts, tips, or advice in a stoic manner. Instead, wording of content needs to be positive, optimistic, and nurturing.
	Refrain from advertising or hard-selling LifeBuoy	I think it is very important that we don't come off as a “Here's a corporation that are pretending to care about you” kind of thing, which I know obviously LifeBuoy is not, but it is important to try and not be seen as that. [Advisor #3]	Avoid language that may come across as promoting the app too strongly.
	Frequency and timing	I think it's good to have it once a week to remind people that it is important to look after your mental health, but it's not too much that it's like, “My gosh, I'm being bombarded with having to look after myself”. [Advisor #3] I think 4:00(pm) till 7:00(pm) is good. I do believe that after a certain time, you've already sort of wound down. You're not going to get engagement. I certainly don't want to engage after a certain time of the night. [Advisor #1]	Weekly notifications may have a greater likelihood of being attended to if sent in the late afternoon or early evening on weekdays, once a week.
2. Aesthetic design
	Calming	I feel like nature's always one of those things that a lot of people find it kind of rejuvenating to see … a simple aesthetic stock photo would be my favourite. [Advisor #3] The nature ones would be good for breathing and mindfulness… the colors were nice. I thought the light blue was really calming to come into. [Advisor #1]	Use backgrounds that users find calming; for instance, nature-themed backgrounds with less vibrant colors or a water-themed color palette.
	Clear to read	Instead of just having the plain background, there's like a tiny, semi-transparent white text box behind the actual text, which I think makes a text a lot easier to read. It doesn't overload your brain on trying to find where the words are. [Advisor #3]	Ensure sufficient color contrast between words and their background for easier reading.
3. Option for more detailed content
	Preference for more information	I agree, it (blog) would be a great resource to be able to go to if you wanted to know more, if you finished ‘Isle Know-It-All’ (one of the islands in the LifeBuoy app) in two seconds and you're like, “Oh, I don't know at all yet. I want to know more”. [Advisor #2]	Cater to users with greater information needs.
	Targeted advice on help-seeking	One topic that really stands out for me, that goes in line with the posts that are already there, would be what would happen if you were to tell your psychologist that you have suicidal thoughts or I have suicidal ideation and it's scaring me, sort of thing, what do I do about it? [Advisor #1]	Provide tips for first-time therapy seekers on what to expect and how to manage their suicidal feelings.
