Table 6 Themes and categories illustrating women’s views in response to questions relating to participating in future trials on anti- stretch mark products

Influencers: Future trial participation

I want a good quality product with a good name

I suppose it would be dependent on maybe reputation of it. Because I’ve heard [product name] is very good. Or I suppose if there was some study that showed that using that certain oil was seen to reduce the stretch marks by a certain percentage I suppose that would swing me towards using it. (Participant 1)

I don’t actually really know if there was any, a moisturiser or that, that was effective […] I suppose research behind it. (Participant 2)

… knowing the product and it being a product I would have heard of would probably gain my interest a little bit more. (Participant 3)

Just something a little bit more organic and something that, yeah as I said absorbs into the skin, not a big film sitting on your skin. Yeah, just something kind of not too heavy … (Participant 4)

...I would do research based on recommendations. That you know to find out if it’s actually as good as the price... (Participant 6)

...I suppose if you have got trials if you had trials done already and you had a little bit of evidence that could support it … (Participant 10)

...I suppose I would be more I would be swayed more by I suppose results or you know previous sort of you know if there was any if there was previous tests done. (Participant 13)

Incentives may be helpful

Incentives like that [money] wouldn’t, no. (Participant 2)

… I suppose a discount on the product. (Participant 3)

...I suppose if I was a little bit more interested in it, it might persuade me if you got some little gift at the end of it. (Participant 5

… if there is a voucher at the end of it I wouldn’t turn it down either. (Participant 6

Yes I think an incentive like that be put in a draw or that you could win something that would definitely encourage people to be part of it. (Participant 8)
