We examined the impact of between-subjects EOT group status (abstainer, relapser, and control) and its interactions with session on postquit retrospective questionnaires (CES-D, PANAS, and WSWS), with baseline retrospective questionnaires as covariates. Significant main effects for EOT group status were found for PANAS NEG, F(2, 105) = 11.63, p < .0001; WSWS Anger, F(2, 104) = 5.50, p < .005; WSWS Anxiety, F(2, 104) = 7.92, p < .0006; WSWS Craving, F(2, 104) = 7.58, p < .0008; and WSWS Sadness, F(2, 104) = 11.90, p < .0001. A consistent pattern emerged for the EOT group status main effect, with relapsers producing larger scores than controls for all of these retrospective measures (see Table 4). However, relapsers did not differ from abstainers on these measures. There were no significant main effects or interactions involving EOT group status and session on postquit CES-D, PANAS POS, WSWS Concentration, WSWS Hunger, or WSWS Sleep. Overall, the analyses of the retrospective questionnaires found that only relapsers experience greater postquit negative affect than controls.
