Suggestions for improving the intervention according to participating healthcare attendees and professionals

	Healthcare attendees	Primary healthcare professionals and assistant researchers	Quotations
Training		More practical training, in particular, regarding the online case report form. More training on motivational interview and on the approach to risk of depression.	‘I think that the concepts were explained, they talked about nutrition, this and that… but not with the platform and we needed to do it in front of the platform. More practical workshop, practice it before starting and for all of us to do the same’ (female nurse, 61 years, Castilla-La Mancha).
Organisation and coordination		Improve the flow of information and communication within institutions and work groups. Specify the responsibilities of each professional (what, how, when and where). Create a shared agenda. Involve all staff in the PCC. Guarantee connectivity and computers in working order. Shift current agenda to commit more time to health promotion. Actively involve community and institutions.	‘Regarding the project coordination for doctors and nurses, maybe the area of community prescription with other organisations and entities’ (male physician, 62 years, Castilla-León). ‘It is important that we get involved and that the authorities get on board to disseminate the healthy lifestyles, what we have now with food in the supermarkets, to label fat and sugars much more clearly, in short, we need to send the message that nutrition is crucial. This will determine if we are more or less sick in the future, and the same goes for depression. I mean, if we do not take it seriously now we will end up with wonderful medicines to patch up all these diseases but…’ (female physician, 43 years, Andalusia).
Recruitment		Extended period avoiding peak times. Extend consultation length. Involve all staff in the PCC.	‘And the recruitment has been hard, because when we have got 60, it means that we have seen 120. Or even more than that. And of course, and this within the daily schedule is hard. In fact, it’s not even feasible. You can only do this for a short while’ (female nurse, 61 years, Castilla-La Mancha).
Individual intervention	Continuity of follow-up. Increase frequency of visits to be able to talk. More specific advice.	Availability of referral specialists for each type of behaviour (each professional should manage the behaviours where she feels more competent). Promote the motivational interview. Social assessment of participant. Consider the results perceived by the people. Continuity of follow-up. Promote the role of nursing in the follow-up.	‘Well… I’d say that… it’s working fine with these improvements I’ve just mentioned … extend length of consultation… give direct advice…’ (man, 51 years, healthcare attendee, Aragon). ‘I would add some manner of social assessment, some evaluation of social interaction… of going out, if she socialises… For instance, I would include more questions on prevention of social isolation…’ (female nurse, 62 years, Aragon).
Group intervention	Enhance group activities.	Enhance group activities.	‘Actually… the… the topic… I think it is well presented… maybe what I missed was… well… what I mean with a meeting… not with a big group… perhaps six or eight people… for each person to be able to talk about what they want to talk… what they do… (man, 64 years, healthcare attendee, Aragon).
Community intervention		Reaching out to the community.	‘I really believe that we need to change, we need to completely rethink nursing, because it should become more community oriented, we should reach out more. It is already happening in other countries like Great Britain and others, where the nurse spends more time in the community than inside the consultation room of the surgery, that’s why I reckon that they’ll need to rethink, I don’t know, it’s just my opinion’ (female physician, Balearic Islands).
Patient information leaflets		Review patient information leaflets on physical activity and depression.	‘… with stretching exercises, with… an idea of the type of exercise recommended for them, I think. Some more guidance, because I’m not an expert on this, I know very little about it, really, as a professional, and as a patient it’s even worse’ (female nurse, Basque Country).
SMS	Pay attention to time when sending SMS.		‘Yes, about that… once I got an SMS at 12.30 at night, at 12.30 at night it does not make any sense, I’m on standby for my father and the phone might ring’ (man, 59 years, healthcare attendee, Catalonia).
Webpage		More dynamic, user-friendly and practical.	‘And after the ICT tool, I would like to see a warning like a summary with a very clear idea of what you have to do next, you know “book an appointment in a month” or “no”, you know?’ (female physician, 45 years, Balearic Islands).
Online case report form		Easier and more practical. Possibility during follow-up to register priority changes in the behaviours or risks to be modified. Systematic recording of drop-outs and causes.	‘Yet again, this platform does not allow you to register the commitment of the patient and it is not practical. It does not reflect the agreement that you reach with the patient and the one suggested is so cumbersome that it is impossible to fulfil…’ (male physician, Balearic Islands).
Evaluation of the intervention (assistant researchers)	Explain results of questionnaires and tests during the visit.	Structured support for the assistant researchers. Move the 3-month blood test to 6 months.	‘That the assistant researchers were here on a permanent basis. For the whole duration of the study. Not just come one day and we’ll see. Here during our same working hours’ (female nurse, 31 years, Castilla-La Mancha).
Project dissemination	Use of various strategies to disseminate to the community the different phases of the project and the results.	Use of various strategies to disseminate to the community the different phases of the project and the results.	‘I’d say that mainly, for instance mmm.… How can I put it? Go some day to places like a marketplace, you know, to talk to people’ (woman, 47 years, healthcare attendee, Catalonia). ‘… to promote it, so that people know it exists, and of its purpose when they see it, listen what is this in that case I’d like, I mean, for people to see that this study is happening, experimental or pilot or whatever you call it, but that they can access that programme, that screening’ (female nurse, 60 years, Castilla-La Mancha).
