<details> <summary><b>Answer &
Rationale</b></summary> <b>Answer: C) Psychotherapy has
a biological basis that influences neurotransmitter systems and
neural circuitry.</b> Rationale: Research demonstrates that
psychotherapy produces measurable changes in brain structure
and function. Unlike pharmacological agents that typically target
specific receptors, psychotherapy induces broad, complex
neurobiological changes. Studies have shown that successful
psychotherapy normalizes activity in the prefrontal cortex,
amygdala, and hippocampus, particularly in conditions such as
PTSD, depression, and anxiety disorders. Psychotherapy also
influences neurotransmitter systems, including serotonin,
dopamine, and norepinephrine pathways. The biological basis of
psychotherapy is foundational to understanding that "talk

therapy" is not merely supportive but actively modifies brain
function and structure. </details>
2. According to the biopsychosocial model, effective
psychotherapy must address:
A) Biological factors only
B) Psychological factors only
C) Biological, psychological, and social factors in an
integrated manner

psychological, and social factors in an integrated manner.</b>

George Engel, posits that health and illness result from the
dynamic interaction of biological (genetics, neurochemistry),
psychological (thoughts, emotions, behaviors), and social (family,
culture, socioeconomic status) factors. Effective psychotherapy
integrates all three domains. Individual, family, group, and
couples therapy modalities apply the biopsychosocial model in
different configurations, but all recognize that mental health
cannot be reduced to biology alone or psychology alone.
