Acceptability
a) Relevance: participants reported that the brochure was fit for purpose and reflected their reality. Most participants reported experiencing the listed adverse effects or withdrawal symptoms and agreed with the reasons provided about why people keep taking antidepressants, such as fear of relapse:
‘The first five [adverse effects] are all a part of my reality.’
(Patient [P] 09, female[F]
Several participants expressed frustration at not having information on adverse effects, clinical guideline recommendation and withdrawal symptoms earlier. One participant reported that the information could have been life- changing for them:
‘Had I had that impression, I could have done something, my life would have been quite different […] I have suffered “weight gain, low sex drive, inability to achieve orgasm, emotional numbing, fatigue, lack of motivation and sleep disturbance” for the last 18 years. I only needed to go through that for 1 year. I wish I had that information […] I would have not been on [antidepressants] for so long unnecessarily.’
(P08, F)
b) Self-reported learning: participants were unaware that antidepressant use is so common, and some were surprised to learn that antidepressants were recommended for only 6–12 months and not for life:
‘I’m blown away by the one in seven [1 in 7 people in Australia] I sometimes feel like I’m the only one I know […] I just thought once you’re on them, you’re on them forever.’
(P10, F)
‘I wish I’d known that […] especially the 6 to 12 months being a therapeutic guideline […] I would have stopped even more gradually and suffered less withdrawal symptoms if I had this information.’
(P08, F)
Many participants did not know that withdrawal symptoms are commonly experienced when stopping antidepressants. Some misconstrued them as relapse:
‘It hadn’t really occurred to me to think about the difference between the withdrawal symptoms and relapse. So that’s useful information.’
(P06, F)
c) Motivational: the brochure prompted participants to reflect on their antidepressant use, with many reporting it could act as an impetus to consider stopping antidepressants:
‘Knowing especially the 6 to 12 months [guideline] […] has made me more aware that perhaps it’s time to start not taking them […] I think this information is definitely getting me thinking about what and when I do actually start doing that.’
(P06, F)
d) Design: participants found the brochure clear and easy to understand, particularly the language used:
‘The language is simplistic, and anyone can understand.’
(P05, F)
Optimisation
Participants challenged the accuracy of two statements in an early version of the brochure: the statements that ‘long-term antidepressant use is usually not needed’ and ‘many people incorrectly believe depression to be a lifelong condition caused by a chemical imbalance in the brain’.
In response, both statements were modified. The first to ‘long-term use is not recommended for most people’, and the second to: ‘many people believe depression to be a life-long condition caused by a chemical imbalance in the brain requiring lifelong treatment — which is now known to be incorrect.’
‘To say “long-term antidepressant use is usually not needed ” […] Some people could take offence […] sort of say “well, hang on, you don’t know my circumstances.”’(P04, male [M])
‘The first dot point [bullet point] kind of feels a little bit condescending […] Like “ incorrectly believe depression to be a lifelong condition caused by serotonin deficiency requiring lifelong treatment”, I think that’s quite a widespread belief […] It makes you feel a bit stupid for believing that, if that’s not correct.’ (P14, F)
Some participants were uncertain about how they would attempt to gradually reduce the antidepressant drug dose, given mini doses are not available. In response, information about a chemist needing to compound mini-doses capsules was inserted into the brochure in addition to being already available in the tapering protocol:
‘You can’t simply halve it nicely, to sort of cut them down, which would be nice.’
(P03, F)
In an earlier version of the brochure participants found the term ‘hyperbolic tapering’ difficult to understand. In response, hyperbolic tapering was defined and a visual graph depicting hyperbolic tapering was added:
‘So, you’re saying if you just decrease a small amount at a time instead of going half and half and half? […] A layperson statement in that way would be great because I think that people would struggle with “ brain occupancy [refers to brain receptors and occupancy].”’
(P09, F).
Participants suggested improvements regarding the design of the brochure, including revising the title to make it obvious that the brochure was about stopping antidepressants (as opposed to starting) and changing the image on the front page:
‘The picture looks a little bit desperate […] It kind of gives me a negative vibe, that this is like a hard decision for her to put that pill in her mouth […] It’s not positive.’
