Using PROMIS for measuring recovery after abdominal surgery: a pilot study

Table 3 Construct validity of the PROMIS-PF and PROMIS-APS

A: Correlations of the PROMIS-PF with the WHO-MO and SF-PF
	WHO-MO^a		SF-PF
T0	−0.70		0.92
T1	−0.66		Not measured
T2	−0.84		0.92
T3	−0.76		0.88
B: Correlations of the PROMIS-APS with the WHO-LA-H, WHO-LA-W, WHO-PART and SF-PRF
	WHO-LA-H*	WHO-LA-W*	WHO-PART*	SF-PRF
T0	−0.71	−0.76	−0.89	0.72
T1	−0.61	−0.55	− 0.80	Not measured
T2	−0.62	−0.68	− 0.65	0.58
T3	−0.91	−0.76	− 0.69	0.69

Correct expected correlations are highlighted in bold
T0: one week before surgery. T1: one week after surgery. T2: three weeks after surgery . T3: five weeks after surgery
WHO-MO: Mobility subscale of the WHODAS. SF-PF: Physical Role Functioning subscale of the SF-36. WHO-LA-W: Life Activities-Work subscale of the WHODAS. WHO-LA-H: Life Activities-Household subscale of the WHODAS. WHO-PART: the Participation subscale of the WHODAS. SF-PRF: Physical Role Functioning subscale of the SF-36
^*Correlations are negative because higher WHODAS scores indicate more impairment regarding mobility
