Which of the following is NOT considered a social factor contributing to mood disorders?

Biological predisposition is not considered a social factor contributing to mood disorders because it refers to the inherent genetic or physiological characteristics that can influence an individual’s risk for developing these disorders. These biological factors might include genetic mutations or neurochemical imbalances that predispose someone to mood disorders, but they do not arise from social environments or interactions.

In contrast, life events, substance use, and trauma or abuse are all social factors influenced by external circumstances and personal interactions. Life events involve significant changes or stressors, such as the loss of a loved one or major transitions in life, that can impact emotional well-being. Substance use can create or exacerbate mood disorders through its effects on brain chemistry and by disrupting social relationships. Trauma or abuse encompasses experiences that significantly affect a person's mental health and can lead to the development of mood disorders. These factors are derived from an individual's social context and interactions, making them relevant to the discussion of social factors in mood disorders.
