- Understanding the dynamic interplay of daily experiences is crucial for personality disorder research.
Purpose of the Study:

- To examine the influence of dispositional interpersonal problems and daily stress on these dynamics in individuals with personality disorders.
Main Methods:
- A naturalistic study design utilizing 100-day daily diaries.
- Multilevel modeling to analyze data from 101 individuals diagnosed with personality disorders.
Main Results:
