Included studies used several tools for measuring the severity of depressive symptoms, namely the Hamilton Depression Rating Scale (HAM - D), 21 22 30 34 35 Patient Health Questionnaire - 9 (PHQ - 9), 24 36 Geriatric Depression Scale (GDS), 23 26 28 Hopkins Symptom Checklist - 20 (HSCL - 20), 37 38 Montgomery - Asberg Depression Rating Scale (MADRS), 18 25 27 Beck Depression Inventory - Fast Screen (BDI - FS) 39 and Center of Epidemiologic Studies Depression Scale (CES - D).40 These tools have different score ranges (HAM - D = 0 — 53, PHQ - 9 = 0 — 27, GDS = 0 — 15, HSCL - 20 = 0 — 4, MADRS = 0 — 60, BDI - FS = 0 — 21 and CES - D = 0 — 60), with higher scores in all tools representing increasing severity of depressive systudies used several tools for measuring the severity of depressive symptoms, namely the Hamilton Depression Rating Scale (HAM - D), 21 22 30 34 35 Patient Health Questionnaire - 9 (PHQ - 9), 24 36 Geriatric Depression Scale (GDS), 23 26 28 Hopkins Symptom Checklist - 20 (HSCL - 20), 37 38 Montgomery - Asberg Depression Rating Scale (MADRS), 18 25 27 Beck Depression Inventory - Fast Screen (BDI - FS) 39 and Center of Epidemiologic Studies Depression Scale (CES - D).40 These tools have different score ranges (HAM - D = 0 — 53, PHQ - 9 = 0 — 27, GDS = 0 — 15, HSCL - 20 = 0 — 4, MADRS = 0 — 60, BDI - FS = 0 — 21 and CES - D = 0 — 60), with higher scores in all tools representing increasing severity of depressive syStudies Depression Scale (CES - D).40 These tools have different score ranges (HAM - D = 0 — 53, PHQ - 9 = 0 — 27, GDS = 0 — 15, HSCL - 20 = 0 — 4, MADRS = 0 — 60, BDI - FS = 0 — 21 and CES - D = 0 — 60), with higher scores in all tools representing increasing severity of depressive symptoms.

Epidemiologic and public health research highlights a robust connection between social factors and physical health.10 Following this approach, several studies have now identified specific environmental and child factors associated with an increased likelihood of injury in young children21 (but see reference 22).

Several studies have addressed the validity of the parent - reported SDQ in school - aged samples, predominantly confirming the intended 5 - factor structure.5, 6 A 3 - factor configuration of externalizing (conduct problems and hyperactivity), internalizing (emotional and peer problems), and prosocial factors has also been proposed and suggested for use in epidemiologic studies and in low - risk populations.7, 8 The internal reliability of SDQ subscales has been predominantly examined by using Cronbach's α, a measure of the interrelatedness of items; however, α estimates are a lower bound for reliability and is often underestimated.9 A meta - analytic review reported weighted mean α coefficients extracted from 26 studies that showed generally modest reliabilities for parent reports (0.53 < α < 0.76).10 McDonald's ω, which estimates the proportion of a scale measuring a construct, typically yields higher reliability estimates but has rarely been used to assess reliability of the SDQ.
