Reliability of a tool for measuring theory of planned behaviour constructs for use in evaluating research use in policymaking

Table 1 Internal consistency reliability coefficients

Construct	alpha^a	G^b
Behavioural intention	0.89	G_1 = 0.73, G_2 = 0.89
Attitude	0.73	G_1 = 0.42, G_2 = 0.85
Subjective norm	0.79	G_1 = 0.49, G_2 = 0.83
Perceived behavioural control	0.68	G_1 = 0.34, G_2 = 0.75

^aT1 and T2 scores were averaged for each item prior to being submitted to the internal consistency analysis.
^bCoefficients were calculated using T1 scores (G_1) and the average of T1 and T2 scores (G_2).
