A new PHQ-2 for Chinese adolescents: identifying core items of the PHQ-9 by network analysis.

BACKGROUND: The importance of preventing and treating adolescent depression has been gradually recognized in Chinese society, especially in the context of the COVID-19 pandemic. Early screening is the first step. The Patient Health Questionnaire-9 (PHQ-9) is a leading scale in the field of depression screening. To improve screening efficiency in large-scale screening, an even shorten scale is desirable. The PHQ-2, which only included two items measuring anhedonia and depressed mood, is an ultra-form of the PHQ-9. However, emerging evidence suggests that there may be a better short form for the PHQ-9, especially for adolescents. Therefore, using two large samples of Chinese adolescents, this study aimed to identify the core items of the PHQ-9 and examine the short form consisting of core items. METHODS: Surveys were conducted among primary and middle school students in two Chinese cities with different economic levels during the COVID-19 pandemic. Two gender-balanced samples aged 10 to 17 (nSample 1 = 67281, nSample 2 = 16726) were collected. Network analysis was used to identify the core items of the PHQ-9, which were extracted to combine a short version. Reliability, concurrent validity, and the receiver operating characteristic curve (ROC) of the short form were examined. Analyses were gender-stratified. RESULTS: Network analysis identified fatigue and depressed mood as core items in the PHQ-9 among Chinese adolescents. Items measuring Fatigue and Mood were combined to be a new PHQ-2 (PHQ-2 N). The PHQ-2 N displayed satisfactory internal consistency and current validity. Taking the PHQ-9 as a reference, the PHQ-2 N showed higher ROC areas and better sensitivity and specificity than the PHQ-2. The optimal cutoff score for the PHQ-2 N was 2 or 3. CONCLUSIONS: Fatigue and depressed mood are the central symptoms of the depressive symptom network. The PHQ-2 N has satisfactory psychometric properties and can be used in rapid depression screening among Chinese adolescents.

Validity of the PHQ-2 questionnaire for the detection of depression in Colombian health personnel during Covid-19 / Validez del cuestionario PHQ-2 para la detección de depresión en personal sanitario colombiano durante Covid-19

RESUMEN: Introducción: La sintomatologia depresiva en profesionales de la salud asociado a crisis virales es de alta prevalencia a nivel global, siendo su detección una prioridad por lo cual, el objetivo de esta investigación fue analizar la validez convergente y consistencia interna del cuestionario de salud del paciente-2 (PHQ-2) en profesionales sanitarios. Método: Estudio eSalud donde se recopilaron datos transversales en línea (n=725), de 281 médicos generales, 237 médicos especialistas y 207 enfermeras durante la cuarentena colombiana, entre el 20 de abril y el 10 de agosto de 2020. Edad promedio 41,3 años (± 8,76). El 38,4% eran hombres (278) y el 61.6% mujeres (447). El 66.1% del personal sanitario atendió pacientes contagiados por coronavirus y el 33,9% no prestó estos servicios. Se administró la versión de 9 ítems del PHQ, validada en población colombiana junto a la versión de 2 ítems del PHQ. Resultados: Se encontró una alta correlación entre las escalas (r=.860, P<0.001), demostrando la validez convergente del PHQ-2 para medir la sintomatología depresiva. La consistencia interna del PHQ-2 fue adecuada, con un Alpha de Cronbach de 0.80 (I.C.= 0.76 - 0.83). Conclusiones: El PHQ-2 presenta adecuados estándares psicométricos de confiabilidad y validez, por lo que su rápida administración, fácil calificación e interpretación, lo convierte en un instrumento confiable y valido para la detección rápida, sin sobrecargas laborales, de los síntomas depresivos en médicos y enfermeras que atiendan o no pacientes en condiciones de brotes virales.

ABSTRACT Background: Depressive symptomatology in health professionals associated with viral crises is highly prevalent globally, being its detection a priority. Therefore, the objective of this research was to analyze the convergent validity and internal consistency of the Patient Health Questionnaire (PHQ-2) in healthcare professionals. Method: E-Health study where cross-sectional data was collected online (n = 725), from 281 general practitioners, 237 specialist doctors and 207 nurses during the Colombian quarantine, between April 20 and August 10, 2020. Average age 41.3 years (± 8.76). 38.4% were men (278) and 61.6% women (447). 66.1% of health personnel treated patients infected with coronavirus and 33.9% did not provide these services. The 9-item version of the PHQ was administered, validated in the Colombian population together with the 2-item version of the PHQ. Results: A high correlation was found between the scales (r = .860, P <0.001), demonstrating the convergent validity of the PHQ-2 to measure depressive symptomatology. The internal consistency of the PHQ-2 was adequate, with a Cronbach's Alpha of 0.80 (I.C. = 0.76 - 0.83). Conclusions: The PHQ-2 has adequate psychometric standards of reliability and validity, so its rapid administration, easy qualification and interpretation, makes it a reliable and valid instrument for the rapid detection, without work overload, of depressive symptoms in doctors and nurses whether or not they care for patients with viral outbreaks.

The COVID-19 pandemic in Italy: Depressive symptoms immediately before and after the first lockdown.

BACKGROUND: Italy was one of the first countries to be heavily hit by the spread of the new Coronavirus. Longitudinal studies are needed to investigate the real effect of COVID-19 on adult mental health. The Italian Twin Registry carried out a study to investigate, over time, the course of depressive symptoms in the general population. METHODS: The study relies on data collected just before the beginning (February 2020) and the end (June 2020) of the first lockdown. Symptoms of depression were assessed using the Patient Health Questionnaire, and total scores or categorized depression scores were considered in the analyzes. RESULTS: A total of 1690 adult twins were recruited. The study showed a mean depression score of 1.11 immediately before lockdown and 1.20 immediately after, with an overall prevalence of depressive symptoms increasing from 33.6 to 38.9%. Depressive symptoms immediately after the restriction period were associated with Covid-19 symptoms affecting households, financial problems due to the pandemic and poor social support. Independently of the baseline risk of depressive symptoms, we observed an increased risk among younger and less educated people. Compared to the pre-lockdown period, women and middle-aged people also were found to be at greater risk of developing depressive symptoms. LIMITATIONS: Possible participation bias and residual selection bias. CONCLUSIONS: The study shows that the COVID-19 pandemic was associated with an increased depressive symptomatology and that, in such health emergency times, the most vulnerable persons are young adults, women, and those living in a socially, culturally, or economically disadvantaged environment.

Implementing Home Office Work at a Large Psychiatric University Hospital in Switzerland During the COVID-19 Pandemic: Field Report.

BACKGROUND: During the COVID-19 pandemic in 2020, psychiatric hospitals all over the world had to adapt their services to the prevailing governmental regulations. As a consequence, home office use and telepsychiatry boomed. OBJECTIVE: The purpose of this study was to evaluate the potential of home office use, its adoption, and the association of home office use with employees' mental health in a large psychiatric university hospital in Switzerland. METHODS: We obtained and analyzed home office implementation and use data from the psychiatric university hospital's information technology services. We also conducted a cross-sectional web-based survey to assess the employees' attitudes toward the clinic's crisis management during the COVID-19 pandemic in early 2020. Part of this web-based survey consisted of questions about home office use between March and June 2020, attitudes toward home office implementation, and mental health. Three mental health measures assessed depressive symptoms (Patient Health Questionnaire [PHQ]-2), anxiety (General Anxiety Disorder [GAD]-2), and stress factors (stress module of the PHQ-D); a cut-off score ≥3 was used for the PHQ-2 and GAD-2. RESULTS: Of the 200 participating employees, 69 reported that they had worked from home at least partially (34.5%). Home office use differed significantly across professional groups (χ162=72.72, P≤.001, n=200). Employees experienced neither depressive symptoms (mean 0.76, SD 1.14) nor anxiety (mean 0.70, SD 1.03). The employees reported minor psychosocial stressors (mean 2.83, SD 2.92). The number of reported stress factors varied significantly across groups with different levels of home office use (χ42=9.72, P=.04). CONCLUSIONS: In general, home office implementation appears to be feasible for large psychiatric hospitals, however, it is not equally feasible for all professional groups. Professional groups that require personal contact with patients and technical or manual tasks must work onsite. Further evaluation of home office use in psychiatric hospitals up to the development of clinics that function merely online will follow in future research. The situation created by the COVID-19 pandemic served as a stepping stone to promote home office use and should be used to improve employees' work-life balance, to save employers costs and foster other benefits.

Psychological Impact of the COVID-19 Pandemic on Licensed Full-Time Practicing Nurses Undertaking Part-Time Studies in Higher Education: A Cross-Sectional Study.

Frontline nurses face an unpreceded situation with the coronavirus disease (COVID-19) pandemic, and many report suffering from physical and psychological stress. This online, cross-sectional survey used questionnaires, such as the Generalized Anxiety Disorder (GAD-7) questionnaire, the Patient Health Questionnaire (PHQ-2), the Connor-Davidson Resilience Scale, stress-related questions, and Brief Coping Orientation to Problems Experienced (Brief-COPE), to determine the psychological impact of COVID-19 on licensed full-time practicing nurses undertaking part-time studies in higher education. Recruitment commenced from August to September 2020; 385 students were approached, and 124 completed the survey (response rate: 32%). Most of the respondents were frontline nurses working in public sectors (89.5%), 29% of whom reported symptoms of depression, and 61.3% reported mild to severe levels of anxiety. The GAD-7 was significantly associated with the resilience score (ß = -0.188; p = 0.008) and exhaustion (ß = 0.612; p < 0.001). The PHQ-2 was significantly associated with 'anxiety about infection' (ß = 0.071; p = 0.048). A lower anxiety level was significantly associated with a higher resilience level and a lower level of exhaustion, and a lower depression level was significantly associated with a lower anxiety about infection. Nursing programs incorporating resilience building may mitigate psychological distress of the study population.

Follow-Up Survey of the Impact of COVID-19 on People Living with HIV during the Second Semester of the Pandemic.

COVID-19 affects persons living with HIV (PLWH) both directly (via morbidity/mortality) and indirectly (via disruption of HIV care). From July-November 2020, an online survey was conducted to investigate the psychosocial well-being of PLWH and changes in HIV care during the second semester of the COVID-19 outbreak. Data were collected on the socio-demographic characteristics of PLWH, their psychosocial well-being, impact of COVID-19 preventive measures on their daily routines and HIV follow-up. Of the 247 responses analyzed (mean age: 44.5 ± 13.2 years; 73.7% male), 67 (27.1%) and 69 (27.9%) respondents screened positive for anxiety (GAD-2 score ≥ 3) and depression (PHQ-2 score ≥ 3), respectively. HIV care had returned to pre-COVID-19 state for 48.6% PLWH, and 108 (43.7%) had no HIV follow-up during the past month. Over three quarters (76.1%) of respondents expressed willingness to receive the COVID-19 vaccine. Compared to previous findings in April 2020, substance use increased from 58.6% to 67.2% (p < 0.001). Our findings suggest that the well-being and medical follow-up of PLWH are still affected after almost a year into the COVID-19 outbreak. Remote HIV follow-up (telemedicine) with psychosocial support should be envisaged in the medium to long-term. Given that most PLWH accept COVID-19 vaccination, they may be prioritized for this intervention.
