Technically sound measures are necessary for accurately identifying youth at risk for depression, but many studies rely on classical test theory metrics or adult samples to evaluate measures. This stu...
Secondary analyses were conducted on data from a study conducted in Midwestern middle schools in which 1224 youth completed the PHQ-8 as part of a battery of surveys. Polytomous IRT analyses (a Graded...
All PHQ-8 items had adequate discriminative abilities. Items measuring anhedonia and psychomotor disturbances performed relatively poorly, and items measuring somatic symptoms (appetite and sleep) wer...
These results might not be generalizable to a broader youth population due to administration setting and the unique demographic characteristics of this sample (76.0 % African American)....
Tools such as the PHQ-8 are appropriate to quickly screen for depression in adolescents, but further scrutiny of adolescent response patterns is warranted. Future research should examine items measuri...
Depression and anxiety symptoms among medical students are often a concern. The Patient Health Questionnaire-Four (PHQ-4), an important tool for depression and anxiety screening, is commonly used and ...
A three-wave longitudinal survey was conducted among healthcare students using the PHQ-4. Structural validity was based on one-factor, two-factor, and second-order factor models, construct validity wa...
The results of the confirmatory factor analysis indicated that two-factor model was the best fit, and LMI was supported at three time points. Inter-factor, factor-total, and construct validity correla...
This study adds new longitudinal evidence that the Chinese version of the PHQ-4 has promising LMI and psychometric properties. Such data lends confidence to the routine and the expanded use of the PHQ...
We aimed to evaluate the psychometric properties of the Brazilian version of the Patient Health Questionnaire (PHQ-8). A study with a sample of 4,170 individuals (≥ 15 years old) from the urban area. ...
PHQ-4, consisting of PHQ-2 and GAD-2, is a widely used screening instrument for depressive and anxiety symptoms in clinical settings and in epidemiological studies. In the present study we provide an ...
Data was collected in two randomly selected samples representative of the German general population in 2020 (N = 2503) and 2021 (N = 2519). We computed percentile norm values for the total sample (N =...
Compared to previous data, only minor changes in normative values were observed. 95 %-thresholds were at a score of 6-7 for the PHQ-4, and 3-4 for PHQ-2 and GAD-2 respectively. The scales showed accep...
Lack of a diagnostic gold standard and suboptimal response proportion (44.2 %) are limitations of this study....
This update supports the continued use of PHQ-4 scales as reliable instruments. For psychometric application, the reported normative data for PHQ-2, GAD-2 and PHQ-4 facilitates more up-to-date compari...
Suicide is a leading cause of death in US youths....
To assess whether screening with supplemental items 10 to 13 on the Patient Health Questionnaire-9 modified for teens (PHQ-9M) improves prediction of youth suicide attempts beyond the information prov...
This retrospective cohort study used a retrospective cohort of adolescents aged 12 to 17 years who were screened for depression in outpatient facilities within a pediatric health care system between J...
Screening with the PHQ-9M....
This study developed and compared prediction using 3 Cox proportional hazards regression models (CR-9, CR-13, and CR-3) of subsequent suicide attempts, determined by the hospital's electronic health r...
Of 130 028 outpatients (65 520 [50.4%] male) with 272 402 PHQ-9M screenings, 549 (0.4%) had subsequent suicide attempts within 1 year following the PHQ-9M screening. The AUROC of the CR-9 model in the...
In this cohort study of adolescent PHQ-9M screenings, the supplemental items on PHQ-9M screening improved prediction of youth suicide attempts compared with screening using the PHQ-9 across all predic...
The PHQ-4 is an ultrabrief screening test for depression and anxiety symptoms. The psychometric properties of this test among the population in Chile are unknown. This study was aimed to determine the...
The study considered a nationally representative sample of 10921 people aged 18 and above, in Chile in 2021. Exploratory and confirmatory factor analysis were conducted, and configural, metric, scalar...
The two-factor structure of the PHQ-4 supported the two underlying constructs of depression and anxiety. This model explained 67% of the variance and had excellent fit (CFI: 0.9999; TLI: 0.9994; RMSEA...
The PHQ-4 can be used to assess depressive and anxiety symptoms in population studies, and as a screening test for depression and anxiety in public mental health programs in Chile....
To examine the factor structure and psychometric properties of the Patient Health Questionnaire for Adolescents (PHQ-A) in Chinese children and adolescents with major depressive disorder (MDD)....
A total of 248 MDD patients aged between 12 and 18 years were recruited and evaluated by the Patient Health Questionnaire for Adolescents (PHQ-A), the Center for Epidemiological Survey Depression Scal...
CFA reported adequate loadings for all items, except for item 3. Macdonald Omega coefficient of the PHQ-A was 0.87. The Spearman correlation coefficient of the test-retest reliability was 0.70. The Pe...
The PHQ-A presented as a unidimensional construct and demonstrated satisfactory reliability and validity among the Chinese children and adolescents with MDD. A cut-off value of 7 was suggested for rem...
Our study aims to examine the factor structure, validity, and reliability of the combined scale Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS) among people with HIV (PWH) in Vietn...
Baseline data from an alcohol-reduction intervention trial among ART clients in Thai Nguyen, Vietnam were used for this analysis (...
The prevalence of clinically meaningful depression and anxiety symptoms was 7% and 2%, respectively, while 19% had distress symptoms. A bi-factor model had the best fit to the data (RMSEA = 0.048; CFI...
Our study supports the use of a combined scale to measure general distress for PWH, which has good validity, reliability and is unidimensional enough to justify the use of a composite depression and a...
Our study aimed to validate culturally adapted English and Swahili versions of the Patient Health Questionnaire-9 (PHQ-9) for use with adolescents in Kenya. Criterion validity was determined with clin...
A total of 250 adolescents comprising 148 (59.2%) females and 102 (40.8%) males aged 10-19 years (mean = 14.76; standard deviation = 2.78) were recruited. The PHQ-9 was administered to all respondents...
The internal consistency (Cronbach's α) for PHQ-9 was 0.862 for the English version and 0.834 for Swahili version. The area under the curve was 0.89 (95% confidence interval, 0.84-0.92) and 0.87 (95% ...
Psychometric properties were comparable across both English-adapted and Swahili-adapted version of the PHQ-9, are reliable, and valid instrument to detect major depressive disorder among adolescents w...

Test accuracy and internal consistency. The PHQ-2 is composed of the first 2 questions of the PHQ-9 (targeting core depression symptoms of depressed mood and anhedonia; a score of 3 or higher (score r...
Ten cross-sectional studies involving 5164 Spanish-speaking adults (mean age range, 34.1-71.8 years) were included; most studies (n = 8) were in primary care settings. One study evaluated the PHQ-2, 7...
In this systematic review and meta-analysis, limited available evidence supported the use of the Spanish-language PHQ-2 and PHQ-9 in screening for MDD, but optimal cutoff scores varied greatly across ...
