Answer:
Personality can not exist in a social vacuum, thus there aren't any individual differences in personality that exist independently of the social context.
Several authors which have written about personality, relationships and health such as Markey and Markey (2013), states the importance of interactions and relationships to determine personality and its grade of conscientiousness.
Other components of personality in the 5-Factor Model of personality like Extraversion, Agreeableness, among others, examine health and social relationships for understanding disorders of personality.
Nevertheless, a social vacuum is a theoretical construct that can not be studied in reality, therefore there is not a personality that exists in a social vacuum.
