Sociology- Notes on Depression Research, Therapist Supervision, and Correlational Analysis

Context and Research Question

  • Social science education in Iceland is limited.

  • Core research question: How do antidepressants affect depression levels? This aligns with treatment-outcome studies.

Research and Ethical Considerations

  • Pharmaceutical funding requires evaluating potential biases.

  • Example: Clinical supervision reduces therapist vicarious trauma, benefiting both therapists and clients.

Data Analysis: Correlation

  • Correlation measures the statistical relationship between variables.

  • Key Concept: Correlation (rr) does not imply causation.

Formulas

  • Pearson Correlation Coefficient: r=∑(X∗i−Xˉ)(Y∗i−Yˉ)∑(X∗i−Xˉ)2  ∑(Y∗i−Yˉ)2r = \frac{\sum (X*i - \bar{X})(Y*i - \bar{Y})}{\sqrt{\sum (X*i - \bar{X})^2} \; \sqrt{\sum (Y*i - \bar{Y})^2}}

  • Covariance: Cov(X,Y)=E[(X−μ∗X)(Y−μ∗Y)]\text{Cov}(X,Y) = E[(X - \mu*X)(Y - \mu*Y)]

  • These formulas show how variables move together.

Overall Implications

  • This connects statistics to real-world issues like treatment and therapist well-being.

  • Ethical challenges include sponsorship bias and the correlation vs. causation distinction in research.
