Final answer:
A step in the process of using the dimensional personality disorder model is identifying multiple, intersecting trait dimensions, as per the Five Factor Model (openness, conscientiousness, neuroticism, agreeableness, and extraversion).
Step-by-step explanation:
One of the steps in the process of using the dimensional personality disorder model is c) Identifying multiple, intersecting trait dimensions. This approach is based on the recognition that personality traits exist along a continuum and are not merely present or absent. The Five Factor Model, or the 'Big Five', which includes openness, conscientiousness, neuroticism, agreeableness, and extraversion, reflects this perspective by categorizing personality traits across spectrums, rather than into binary categories.
The Dimensional Personality Disorder model provides a way to conceptualize personality disorders in a more nuanced and granular manner, taking into account the individual differences and complexities of each person's personality structure.
