The fact its qualitative means its about quality not quantity! How many you need depends on whether you get enough info out of your data to answer your research question, only you (with advice from your supervisors) will be able to decide if the number of interviews you have is enough. I have around 24 interviews, all around an hour long. I'm hoping its enough as my submission is in 4 weeks! Those interviews have resulted in masses of rich data, which alongside my literature review/ theory are able to explain the causal patterns in the programme I am researching. Basically, I feel they answer my research question sufficiently (not completely, as there will always be further questions that arise from the data). The number is less important than how you justify your decision, eg. have you recruited 21 just because its hard getting anymore, or because you feel its enough for what you want to achieve? Try not to compare your research with other peoples, I know its tempting, but it isn't helpful and can make you lose confidence in your own work! Would it be possible to leave yourself time so you can secure more interviews at a later date if you feel your analysis is lacking? As for methods to recruit - that's really difficult to comment on without knowing the context eg. group you are recruiting and what for, and any changes to recruitment methods may need an amendment to your ethical approval. My discipline is health/ social care, so for that area I would recommend engaging with/ advertising in the relevant local groups. Hope some of that helps! Good luck!!

To cut a long story short, the first 2.5 years of my PhD went fairly well. I did the usual, planned the project, collected my data, passed the Mphil transfer, conferences, teaching. Then divorce, ill health and all kinds of things happened. I interrupted for 2 years whilst trying to get my life back on track and came back to studying with a year left (extension). Restarting coincided with the pandemic, my life was still chaotic (single mum of 3, several changes to jobs/house move), I suffered depression and a mini breakdown. Somehow I've managed to pick myself up, the first half of my thesis (40,000 words) is written up to a reasonable standard, but I've got little else. Now I have less than 5 weeks left (more extensions are not an option), I just don't know if I can actually pull it off. My data is less than half analysed, I have several interviews I haven't even transcribed which need incorporating. Then I will have my findings, discussion and conclusion to write. Because everything has been so last minute, my supervisors have seen very little of my work, and have no time to read/ comment, so I'm going it alone. They have said that from what I have seen, I am capable, my writing is a good standard, and my main supervisor has agreed I can send everything to her a couple of days before the submission, and she's hoping what I have is good enough to sign off (she has said she will not sign off anything that she thinks will fail). My Viva/ externals are already booked. Last week I was positive, thinking I can do this. My plan was a week to finish analysis, a week to write up analysis, a week to write up discussion, and a week to write conclusion and proof. I've booked 3 weeks leave off work, and could potentially get a 4th week of if necessary. This week I'm not so positive about it. My youngest is off school poorly, I got very little done yesterday and my brain is in a fog. I know that if I do manage to submit something it will need major corrections, but worst case scenario I think I would finish with an Mphil, which at least means the last 5 years wont be a complete waste of my life (I only have a BSc at present so I guess a Mphil is better than nothing). Today I'm feeling lost and unmotivated and have talked myself out of believing it is possible. I have managed to book a week away next week - which means no kids or dog to walk, just me and my laptop. But even so, is it going to be enough or am I being completely unrealistic? Should I go for it, or should I just quit now? I'm already in a post doc job which I love and I'm good at, If I cant pull this off, I won't have a career :(

Thanks for posting this, its just what I needed to hear right now, that someone in a similar position to me did manage to submit!
I'm a single mum to 3 kids, and one nuisance dog that seems to need a walk/play or to be generally naughty every time I start writing. Working as a post-doc which I guess I can't keep if I don't submit. I have 4 weeks left, haven't even finished my analysis. so 4 weeks to finish the analysis, write up the findings discussion and conclusion and proof. I've taken 3 weeks off work, its not enough, but I'm hoping I can patch something readable together in that time. My supervisor has kept a day free 2 days before the submission date to read it through, first time she will have seen the full draft, she has said that I better be confident it will be good enough to sign off!! I'm not at all confident, and feeling the pressure. I've never had any feedback on what I've done so far, so god knows if its up to scratch. Last week I was about to quit, then I thought, hell no! lets just panic write and submit. My thinking is the (almost)worst that can happen is I end up with an Mphil instead of a PhD, and that's surely better than nothing? I started out thinking I was going to do brilliant research, write the best thesis ever written and change the world. Now I just cant wait to hand in something that I know will be substandard so that I can have my life back. I started this 6 years ago (2 year interruption in between) and it has cost me my marriage, my home, my sanity. All I have left is my career, and that's hanging by a thread. Strangely, I'm feeling optimistic about it all (perhaps about it ending one way or another).

Well done on submitting, I bet that was a huge weight off your shoulders, and good luck to anyone else in a similar position!
