Affective instability: the experience of going from baseline mood (which may be a general state of negative affectivity) to intense negative affective states.
States may last hours or a day, and are assumed to be triggered by environmental events (APA, 2000)Distinguishing feature
To capture variability and account for bigger weighted changes we used MSSD. Which allowed us to see affective instability.Using MSSD
***Takes into account temporal order of data points unlike a variance or standard deviation
ASD=7 changes we used MSSD. Which allowed us to see affective instability.
MSSD allows for the assessment of momentary change.
Mean number of drinks for the duration of the study (28 days)
Mean drinking days for the duration of the study (28 days)
The BPD group without lifetime alcohol dependent showed no significant correlations for negative affect instability (n=38)
When observing the 28 days total in the lifetime alcohol dependent borderline personality disorder group found (n=17):
* Correlation is significant at the 0.05 level
