This domain contains indicators of mutually exclusive symptom clusters aligning with disorder classifications laid out by DSM-5/ICD-10 excluding substance misuse. Some codes for self-harm (e.g. overdose) may be represented across both parental mental health problems (MHPs) and parental substance misuse (SM) domains. DSM-5 defines mental health problems as symptoms characterised by clinically significant disturbance in an individual’s cognition, emotion regulation, or behavior that reflects a dysfunction in the psychological, biological, or development processes underlying mental functioning.
MHPs indicators are ascertained using read codes, prescriptions, ICD-10 codes or by meeting the higher cut-off score on a validated self-report instrument or validated algorithms with prescriptions.1. Validated codes for parental MHPs and parental SM are also available via the HDR UK CALIBER phenotype library, with the mapping process described by Kuan et al.
|ACE domain, Indicator(s)||Rule-based algorithms||Scrip/code*|
|mMHPs, Depression||Include if continuous data meets the cut-off assigned to each code (see code list): e.g. DASS-21 (sub-scales): ≥14; EDPS: ≥13; HADS (sub-scale): ≥11; HDRS (sub-scale): ≥ 14; PHQ-9: ≥10; SDS (Zungs’s): ≥50||
|mMHPs, Anxiety||Include if continuous data meets the cut-off assigned to each code (see code list): e.g DASS-21: ≥10; HADS (sub-scale): ≥11; HDRS (sub-scale): ≥18; SAS (Zungs’s): ≥45 score; GAD-7: ≥8||
|mMHPs, Anxiety or depressive symptoms, antidepressants or anxiolytics and mental health service referral/interventions received||Codes referring to anxiety symptoms (e.g., worrying) or depression (e.g. “feeling low”) are only considered a case of depression or an anxiety disorder when the patient was also given antidepressants and/or anxiolytic medication within 3-months or initiated psychological treatment within 2-years. Comparison estimates for mothers in CPRD-MBL with and without this algorithm are provided by Abel et al. Rule: Include symptoms/medications as an anxiety or depression indicator, if a previous diagnostic code or tier 3 intervention code exists (within 2-years), or if there is a co-occurrence of a prescription consistent with a symptom within 3-months (e.g. anxiolytics & anxiety symptoms). e.g. Use the
