Final answer:
A cognitive factor that could influence the development of a psychological disorder according to biopsychosocial models is negative thoughts.
Step-by-step explanation:
According to biopsychosocial models, a cognitive factor that could influence the development of a psychological disorder is negative thoughts. The biopsychosocial model emphasizes the importance of different factors in the development and treatment of mental health conditions, including biological factors (like neurotransmitter imbalances), psychological factors (such as cognitive perspectives, emotions, and behaviors), and social factors (for example, socioeconomic status or past trauma). In this context, negative thoughts represent the psychological component of the model, since they directly relate to the cognitive processing of an individual.
