Thread: Apply for a PhD when already enrolled

Yes, you *can* but I'd think carefully about:

a) Can you shape the current PhD to be what you want to do? If not, why not? If it's that is has restrictive funding requirements - and you're happy to give these up - it would be a good reason. If it's something more nebulous (don't *think* prof would let you do it), be careful these are certainties rather than assumptions before proceeding.

b) Accept that a PhD is often monotonous, repetitive, hard work. This is not a 'bad' PhD, it's often the nature of research. Switching topic will not magically fix this - you'll just realise the thing you thought was interesting is also monotonous, repetitive, hard work to investigate rigorously. Of course, this is a cynical perspective - the ideal situation is you're down the pub on a Friday explaining why what sounds as boring as hell to everyone else is super-interesting - because you're finding the monotonous, repetitive, hard work compelling.

c) It would be up to you, I'd presume, whether you disclose that you're currently doing a PhD elsewhere. As a supervisor I'd rather someone be up-front and explain why they want to switch - and be trying to assess if a) or b) above apply. I'd try to answer these questions to yourself, convincingly, so you can be up front and make the same convincing argument on the application, or rethink things.

A scan of the certificate would be what I'd expect, if I asked for it.

You'd possibly want to bring the certificates to the interview, if this is relevant to your situation. Generally this is more for HRs benefit than the interviewers' - by which I mean, these policies/processes are typically driven by HR rules (which themselves are designed to catch rare/ridiculous 'worst case' scenarios) rather than a burning passion from the professor doing the interview to see a candidate's life history in print, signed in triplicate!

In short - send a quick scan; if they're not happy with it they'll let you know what they do want, and either way it shouldn't affect your chances.

Thread: What is a double-baseline design?

Treatment is started & baselined at different times. Because there are two baselines, we can attempt to infer the treatment is the cause of the effect. This assumes a hypothesis that the treatment's benefit is exposure time related (a reasonable assumption in most forms of behavioural intervention).

e.g. - You do the same depression intervention on two cohorts, which start 1 month apart. You baseline both at start point for respective cohort. Both cohorts report monthly depression-inventory scales. Cohort 1's response markedly improves vs their baseline 3 months later. Cohort 2's markedly improves vs their baseline 4 months later, with them having started the intervention a month later. The fact both baselines improved within a similar duration of exposure to the intervention supports the hypothesis the intervention is the causal factor.

Benefit - all participants are exposed to intervention. This can be important both ethically and pragmatically. But the same could sometimes be achieved with a crossover design.

Drawback - you may still fail to accommodate extraneous factors. For example, if both interventions are led by the same facilitator - is it the content of the intervention, or the skill of the facilitator? Similarly, depending on the temporal aspect, and the power of your stats, something extraneous could still happen in week 2.5 (like a TV documentary on depression), with sufficiently strong an effect to influence both sets of responses.

Presumably there was a rationale for doing both. I would imagine the interviews were there to provide qualitative insight to support or refute the quantitative data.

Whether this is needed, useless, or can be omitted depends very much on your hypothesis and research design. If your survey metric has been validated though other correlations, is well-designed, and has a sample appropriate for your analysis techniques (i.e. is not a fudged ANOVA of 30 Likert responses), then it may stand alone as a contribution worthy of a PhD. Similarly you can build a PhD purely on qualitative work but will have to defend other questions such as how representative the sample is, and how findings might generalise.

Surely if you have the data, a survey would be quick to analyse (though, admittedly, if you have 1,000 hand-filled papers rather than a SurveyMonkey report I'd see the problem). Since you've already undertaken the qualitative work, then if time really is an issue an option might be to pick several interviews as detailed case studies rather than report them all? If transcription is the problem then see if you have budget as a student to pay for this using a service.
