Chapter 5 122 Problem situation ‘experiencing cravings’ – Opinion about the coach’s feedback (Q-2) and opinion on feedback coach to receive personally (Q-3). To find out whether or not the type of coaching feedback (Condition: Validation vs. Focus-onChange vs. Dialectical) had an effect on the probability of a respondent judging the coach's feedback as good (as opposed to not good), a logistic regression analysis was performed. Estimated probabilities of a positive opinion (Q-2 Opinion about the coach’s feedback) for all three conditions are presented in Table 6. In the Focus-on-Change coaching feedback condition the probability of a positive opinion on the coach's feedback was lower than in the Validation and Dialectical coaching feedback conditions. As can be seen in table 6, there are substantial differences between the three conditions in the estimated probabilities with relatively high probabilities in both the Validation and the Dialectical condition. The follow-up question (Q-3) was what the opinion of the women would have been if they personally had received this answer from the coach. Similar results as with Q-2 were revealed. A likelihood ratio test showed that the differences between the three coaching feedback conditions were statistically significant for both Q-2 and Q-3 (respectively c2(2) = 24.8, p < .001, and c2(2) = 25.2, p < .001). Post-hoc pairwise comparisons (Wald tests with Holm correction) indicated that the difference between the Focus-on-Change and Dialectical conditions (OR = 17.1) and the Validation and Focus-on-Change conditions (OR = 30.4) were statistically significant for both Q-2 and Q-3 (respectively OR = 0.06, p < .001, and OR = 0.07, p < .001), but the difference between the Validation and Dialectical conditions was not (resp. (OR = 1, p = 1.00, and OR = 2.11, p = 0.42). The three groups (Validation, Focus-on-Change, and Dialectical) were distinct. The probability of a participant giving a positive rating to Validation was higher than to Focus-on-Change. The probability of giving a positive rating to Dialectical was higher than to Focus-on-Change. Table 6 | ‘Experiencing cravings’.
