The men from the SDPS and COGA subsamples were similar on weight (77.7 (11.9) vs 81.0 (12.57) kg, t = 0.80, p = .43), T1 usual drinks (2.6 (2.50) vs 2.8 (2.897), t = 0.22, p = .83), and T2 drinks (3.7 (2.62) vs 3.4 (2.78), t = 0.36, p = .72), but SDPS men were younger (19.1(1.92) vs 22.8 (3.94), t = 3.08, p = .01). SRE values were similar across the two groups (3.3 (1.94) vs 3.6 (1.36), t = 0.80, p = .43), as were the number of items endorsed (2.6 (0.81) vs 2.9 (0.75), t = 1.08, p = .29) and the SHAS 7 60 min scores (69.6 (40.72) vs 65.3 (61.74), t = 0.22, p = .83).
