Associations with external constructs/variables of PHQ-9 sum score (left) and PHQ-9-based probable depression (right)
PHQ-9 sum score | PHQ-9-based probable depression | |
---|---|---|
Pearson’s correlation (95% CI) | odds ratio per SDb (95% CI) | |

Self-rated mood | −.54 (−.57,−.51) | 0.23 (0.20,0.27) |
Self-esteem | −.50 (−.59,−.39) | 0.39 (0.26,0.57) |
Satisfaction with lifea | −.44 (−.54,−.33) | 0.45 (0.30,0.64) |
Self-rated healtha | −.30 (−.33,−.26) | 0.54 (0.48,0.61) |
Log-income | −.14 (−.18,−.10) | 0.75 (0.67,0.83) |

difference in means (95% CI) | odds ratio (95% CI) | |

Ever vs. never attempted suicide | 2.58 (1.74,3.42) | 2.11 (1.56,2.85) |
Big city vs. not | −0.51 (−1.11,0.08) | 0.89 (0.71,1.13) |
CI = confidence interval; SD = standard deviation.
These scales were only administered to a sub-sample (n=214).
These are odds ratios of probable depression associated with one SD difference in the external variable.
