Figure 2. Negative and Positive Affective Instability Before and After Bulimic Behaviors Compared with Time-Matched Periods on Non-Bulimic Behavior Days.

Figure 2

A) The likelihood of an extreme increase in positive affect (PAC) was significantly higher after bulimic behaviors than during matched time periods on non-bulimic behavior days. B) Average negative affect instability (MSSD) was greater after bulimic behaviors than during matched time periods on non-bulimic behavior days, but average positive affect instability (MSSD) before and after bulimic behaviors did not statistically significantly differ from positive affect instability on non-bulimic behavior days. Error bars represent standard error of the mean. Abbreviations: NA = negative affect; PA = positive affect; PAC = probability of acute change; MSSD = mean squared successive difference. **p < 0.005, ***p < 0.001
