Sensitivity and specificity of PHQ-9 and PHQ-2.Keiko SuzukiShima KumeiMasumi OhhiraTsukasa NozuToshikatsu Okumura
Although sensitivity and specificity are most often reported, predictive values are more clinically relevant. The positive predictive value of a screening tool refers to the probability that a patient with a positive screen will have the condition, whereas negative predictive value is the probability th...
Sensitivity and Specificity Estimates for the PHQ-2 Alone, the PHQ-9 Alone, and for PHQ-2 ≥ 2 Followed by PHQ-9 Among 44 Studies (N Participants = 10,627; N Major Depression = 1,361) That Used a Semi-structured Reference Standard and Had Both PHQ-2 and PHQ-9 Item Scores Available...
The sensitivity and specificity for a cut-off score of three were 75% and 89%, respectively. The values for the depression item of the UPDRS were slightly lower. Conclusion: The PHQ-2 is a valid tool for screening depression in PD. 展开 关键词: Parkinson's disease psychiatric status ...

The score of 3 of PHQ-2 showed the highest Youden's index of 0.79, with both sensitivity and specificity were 0.90 and the AUC was 0.94 (95% CI: 0.90–0.97). Conclusions Both PHQ-9 and PHQ-2 are valid screening instruments for depression in the rural elderly in ...
A weak, but significant correlation was observed between the PHQ and MH domain scores (rho = 0.32, p < 0.001). A cut-off of ≥ 3.6 on the MH domain demonstrated sensitivity of 0.75 and specificity of 0.86 for identifying patients at no–mild risk for depression. Conclusion ...

The meta-analytic area under the receiver operating characteristic curve of the PHQ-9-linear and the PHQ-2 was significantly higher than the PHQ-9-algorithm, a difference that was maintained in head-to-head meta-analysis of studies. Our best estimates of sensitivity and specificity were 81.3% ...
