	2007	2009	2011	Change 2007–2009	Change 2009–2011	Standard deviation (2007)
‘I have adequate materials, supplies and equipment to do my work’	3.22	3.36	3.38	+0.14**	+0.02*	0.18
'There are enough staff at this Trust for me to do my job properly’	2.61	2.78	2.72	+0.17**	−0.06**	0.17
‘I do not have time to carry out all my work’	3.30	3.26	3.25	−0.04**	−0.01	0.21

Results are based on the 309 NHS trusts in England with data from all 3 years shown. p values are based on paired sample t tests. Responses were on a 1–5 scale with 5 indicating greater agreement with statements; an increase of 0.10 is equivalent to 10% of respondents moving up one category of response, for example, from ‘neither agree nor disagree’ to ‘agree’.
