“…Consistent with previous studies in adults [23][24][25][26][27][28][29]39 and adolescents, 33 the current study also found that the Chinese version of the PHQ-9 has a high reliability, as evidenced by the internal consistency (Cronbach' s a = 0.84). The test-retest reliability of the PHQ-9 was fair but slightly lower than in previous reports on adults [27][28][29]40 and adolescents.…”

WHAT'S KNOWN ON THIS SUBJECT: Major depression is common among adolescents. The PHQ-9 has good sensitivity and specificity for detecting depression among adolescents in primary care settings. However, no study has examined the psychometric properties of the PHQ-9 among Chinese adolescents in school settings. WHAT THIS STUDY ADDS:This is the first study to validate the use of the PHQ-9, Patient Health Questionnaire-2 item, and Patient Health Questionnaire-1 item among Chinese adolescents in Taiwan. The PHQ-9 and its 2 subscales have good sensitivity and specificity for detecting depression among school adolescents.abstract OBJECTIVE: The aim of this study was to determine the reliability and validity of a Chinese version of the Patient Health Questionnaire-9 item (PHQ-9) and its 2 subscales (1 item and 2 items) for the screening of major depressive disorder (MDD) among adolescents in Taiwan.METHODS: A total of 2257 adolescents were recruited from high schools in Taipei. The participants completed assessments including demographic information, the Chinese version of the PHQ-9, and the Rosenberg Self-Esteem Scale, and data on the number of physical illnesses and mental health service utilizations were recorded. Among them, 430 were retested using the PHQ-9 within 2 weeks. Child psychiatrists interviewed a subsample of the adolescents (n = 165) using the Kiddie-Schedule for Affective Disorder and Schizophrenia Epidemiological Version as the criterion standard. RESULTS:The PHQ-9 had good internal consistency (a = 0.84) and acceptable test-retest reliability (0.80). The participants with higher PHQ-9 scores were more likely to have MDD. Principal component factor analysis of the PHQ-9 yielded a 1-factor structure, which accounted for 45.3% of the variance. A PHQ-9 score $15 had a sensitivity of 0.72 and a specificity of 0.95 for recognizing MDD. The area under the receiver operating characteristic curve was 0.90. The screening accuracy of the 2 subscales was also satisfactory, with a Patient Health Questionnaire-2 item cutoff of $3 being 94.4% sensitive and 82.5% specific and a Patient Health Questionnaire-1 item cutoff of $2 being 61.1% sensitive and 87.7% specific. CONCLUSIONS:The PHQ-9 and its 2 subscales appear to be reliable and valid for detecting MDD among ethnic Chinese adolescents in Taiwan.

Abstract:Objective: To study the prevalence of alcohol and substance use among medical students. Material and Methods: A cross-sectional study surveyed Prince of Songkla University medical students in 2016. Questionnaires for demographic data, the Alcohol Use Disorder Identification Test (AUDIT), experience with alcohol and substance abuse, and the Patient Health Questionnaire-9 Thai version (PHQ-9) were used. We analyzed the data in order to describe the behavior of subjects by descriptive statistics. The factors associated with alcohol used were analyzed by chi-square test and logistic regression. Results: Seven hundred thirty-nine (70.1%) of medical students completed the questionnaires. Participants, 56.0% were female and 44.0% were male. Mean age was 21.2 years old; 53.3% have drunk alcohol; the gender proportion of drinkers was 60.0% of males and 48.1% of females. By AUDIT, 23.1% of medical students were high-risk drinkers. The most common reason for alcohol consumption was social engagement (91.9%) and the most common reason for not drinking was having knowledge about the harmful health effects of alcohol (51.2%). Of the medical students, 7.6% had experience with substance use. The drugs most commonly used were cigarettes (5.3%) and baraku (4.6%). According to the PHQ-9, 11.2% of all medical students, 12.6% in males and 10.1% in females had depression. However, these high levels of depression did not associate with a high-risk of alcohol consumption. The significant factors that associated with high-risk drinking were gender [odd ratio (OR)=1.9 (1.1-3.4)] and experience with substance use [OR=3.8 (2.0-7.3)]. Conclusion: Half of medical students drank alcohol and approximate 1 in 10 had experience with substance use. Gender and experience with substance use were the significant factors that correlated with high-risk drinking.

The PHQ-9 has been reported to have a single factor in several previous studies Dum, Pickren, Sobell, & Sobell, 2008;Graves & Bombardier, 2008;Hansson, Chotai, Nordstöm, & Bodlund, 2009;Yu et al, 2012), including a study involving more than 5000 primary care patients (Huang, Chung, Kroenke, Delucchi, & Spitzer, 2006).…”

Depression is often overlooked in oncology practice. Depressive module PHQ-9 was not studied in Portuguese cancer patients, despite its brevity and comparable psychometric proprieties to other depression scales. Which are the psychometric properties of the Portuguese version of the PHQ-9 for use with women with breast cancer? Reliability, sensitivity to change and the construct validity will be studied. The purpose of this study is to assess the psychometric properties of the Portuguese version of the PHQ-9 for use with women with breast cancer. This study intends to evaluate the reliability, the sensitivity to change and the construct validity of the PHQ-9 in a Portuguese Breast Cancer women sample. It was reproduced a principal component analysis and explored the reliability and validity of the questionnaire. The validation used a sample of 63 Portuguese women with breast cancer. A test-retest was conducted in 45 women, after 8 weeks. Construct validity was analyzed. PHQ-9 scores ranged from 0-27, with a mean score of 4,92 (SD= 4,63). The scale presented adequate internal consistency (α = .86) and test retest reliability (ICC= .87). It also presented good construct validity, as overall scores and severity levels were strongly associated with functional and symptoms subscales. The principal component analysis explains 48.42% of the variance. The validation process of the Portuguese PHQ-9 version shows metric properties similar to those in international studies, suggesting that it measures the same constructs, in the same way, as the original version. Data provided evidence for the validity of the PHQ-9 as a brief measure of depression severity in Portuguese women with breast cancer.
