95 CHAPTER Cognitive performance during addiction treatment 5 ARCI KS p –value Post–hoc ( n = 82) ( n = 49) < .001*** AUD > ARCI; AUD > KS; ARCI > KS†††† 4.80 (1.40) 2.94 (1.70) 5.50 (0.79) 3.69 (1.31) 5.56 (0.76) 3.73 (1.58) .052††† were found on ADL ( F (2, 345) = 120.33, p < .001, η 2 = 0.411), CO ( F (2, 345) = 186.69, p < .001, η 2 = 0.520) and IP ( F (2, 345) = 25.92, p < .001, η 2 = 0.131; see Table 5.4 for direction of the findings). There was also a significant interaction between time and group on EM ( F (2, 345) = 3.49, p = .032, η 2 = 0.019), showing that emotional lability of patients with AUD did not change over time, while both patients with ARCI and those with KS scored lower on T2 than on T1. Correlation between changes in cognitive performance and everyday cognitive functioning Changes in overall cognitive performance (MoCA–TS) were positively correlated to changes in overall everyday cognitive functioning (PCRS–TS), as rated by both the patient ( r (287) = 0.134, p = .012) and the clinician ( r (297) = 0.256, p < .001). On an exploratory basis, correlations between all change–scores of the MoCA and the PCRS were calculated for the total sample and for all three groups separately (See Table 5.5 and 5.6). Main findings were that overall, correlations were higher for the clinician rating than for the patient rating, and higher for patients with KS followed by those with ARCI and AUD respectively. For the latter, correlations mostly centred zero. The highest correlations were found in patients with KS, where both the change scores of the MoCA–TS and the MoCA–DS orientation correlated significantly with all PCRS–scores of the clinician.
