In Table 3 within person-cross age correlations are presented for the dichotomous CAGE scores (0 vs. 1+ yes answers). For intervals up to 12 years, the correlations were of similar magnitude. For intervals larger than 12 years, the correlations started to decrease, but the number of individuals for whom data was available on these large time intervals was relatively small.Table 3Estimates of tetrachoric within-person correlations (with standard errors and number of observations) for the CAGE as dichotomy (0 vs. 1+ yes answers)15–1718–2021–2324–2627–2930–3215–17118–20.43 (.07) N = 672121–23.41 (.08) N = 616.59 (.04) N = 1,224124–26.38 (.08) N = 540.45 (.05) N = 1,125.65 (.03) N = 1,586127–29.20 (.14) N = 289.47 (.06) N = 840.67 (.03) N = 1,270.75 (.03) N = 1,551130–32.29 (.14) N = 177.48 (.08) N = 455.63 (.04) N = 922.69 (.03) N = 1,147.73 (.03) N = 1,1671
