“…This is supported by a previous study that showed that computerization of the PHQ-9 did not affect its psychometric properties. 28 Compared with PHQ-9, the descriptions in the responses in the QIDS-SR16 are complicated. Sung et al 23 determined that the QIDS-SR16 score was able to distinguish minor from major depression, while the PHQ-9 could not.…”

Purpose: Smartphone-based questionnaires have advantages compared with their paper versions, but there is a lack of consistent research on depressive disorder questionnaires. This study aimed to assess the equivalence between the paper and smartphone versions of the Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR16) and Patient Health Questionnaire-9 (PHQ-9) for patients with depressive disorders in psychiatric hospitals in China. Patients and Methods: This was a randomized crossover study of 110 depressed patients recruited from the outpatient department of Beijing Anding Hospital from March 2016 to September 2018. Group 1 completed both the QIDS-SR16 and PHQ-9 in paper format and then completed the smartphone version 1-2 h later. Group 2 completed the scales in the reverse order. Reliability was evaluated using intraclass correlation coefficients (ICCs) with 95% confidence intervals (CI). The expected ICC was 0.9 (α=0.05). Results: The overall ICC score of the QIDS-SR16 paper and smartphone versions was 0.904 (95% CI: 0.861-0.934), and the ICCs of each item ranged from 0.769 to 0.923. The overall ICC score of the PHQ-9 paper and smartphone versions was 0.951 (95% CI: 0.929-0.967), and the ICCs of each item ranged from 0.779 to 0.914. Conclusion: This study demonstrated the equivalence of the paper and smartphone versions of the PHQ-9 and QIDS-SR16 in depressed patients in China.

“…An additional item assesses severity of daily life limitations associated with depressive symptoms. The computerized version of the PHQ-9 (α = 0.88) and the paper-pencil version (α = 0.89) show equally high internal consistency (34).…”

Background: Farmers show high levels of depressive symptoms and mental health problems in various studies. This study is part of a nationwide prevention project carried out by a German social insurance company for farmers, foresters, and gardeners (SVLFG) to implement internet-and tele-based services among others to improve mental health in this population. The aim of the present study is to evaluate the (cost-)effectiveness of personalized tele-based coaching for reducing depressive symptom severity and preventing the onset of clinical depression, compared to enhanced treatment as usual.Methods: In a two-armed, pragmatic randomized controlled trial (N = 312) with follow-ups at post-treatment (6 months), 12 and 18 months, insured farmers, foresters, and gardeners, collaborating family members and pensioners with elevated depressive symptoms (PHQ-9 ≥ 5) will be randomly allocated to personalized tele-based coaching or enhanced treatment as usual. The coaching is provided by psychologists and consists of up to 34 tele-based sessions for 25-50 min delivered over 6 months. Primary outcome is depressive symptom severity at post-treatment. Secondary outcomes include depression onset, anxiety, stress, and quality of life. A health-economic evaluation will be conducted from a societal perspective.Discussion: This study is the first pragmatic randomized controlled trial evaluating the (cost-)effectiveness of a nationwide tele-based preventive service for farmers. If proven effective, the implementation of personalized tele-based coaching has the potential to reduce disease burden and health care costs both at an individual and societal level.

“…While we might expect that mothers who are not inclined to share these data are also at higher risk for mental health issues, such as depression, the low rate of depressive symptoms is consistent across all sites, including those that had high authorization rates (i.e., rates that were above 95percent authorization). Second, the PHQ was developed to be a self-administered instrument and validated for pen-and-paper as well as electronic administration (Erbe et al, 2016). The reliability of the PHQ when administered verbally has not been well-established (Mission Health, 2018).…”
