When I say "personality," I intentionally mean that in a very broad sense – personality is much more than just mean-levels of traits!
Personality is also more than traits in general, but I do typically abide by a trait perspective in my research.
For me, "trait" is also broadly defined
For practical (and realistic) purposes, and with any niche preferences regarding semantics aside, I consider most relatively stable individual difference constructs that capture someone's typical thoughts, feelings, or behaviors to be "traits"
The Big Five are the traits I most often look at, but impulsivity, sensation-seeking, self-esteem, depression, life goals, and individual temperament traits have also been the focus of my work
Also, while I acknowledge the nomothetic versus idiographic debate and ways of conceptualizing & conducting research on personality, I prefer to view these matters from a variable- versus person-centered perspective.
Some research questions necessitate the use of a variable- versus person-centered approach (and vice versa)
However, I believe it is necessary to conduct research from both perspectives to fully understand personality
