¹ Lifetime N represents the phenotype at any assessment among participants with miRNA data.
² Suicidality phenotypes were only evaluated in the last follow-up (Wave 3).
Diagnoses were assessed using the Development and Well-Being Assessment (DAWBA) following DSM-IV criteria. The table summarizes psychiatric disorders identified among probands at each assessment wave.

5.3 Cumulative Psychiatric Phenotypes

Cumulative Psychiatric Phenotypes Prevalence Across Waves Among Probands with miRNA Data (BHRC)
Psychiatric Phenotype	Wave 1 (N=120)	Wave 2 (N=120)	Lifetime (N=120)¹
ADHD	36 (30.0%)	42 (35.0%)	46 (38.3%)
Anxiety Disorders	32 (26.7%)	50 (41.7%)	57 (47.5%)
Bipolar Disorder or Mania	0 (0.0%)	1 (0.8%)	4 (3.3%)

¹ Lifetime N represents the phenotype at any assessment among participants with miRNA data.
² Suicidality phenotypes were only evaluated in the last follow-up (Wave 3).
Diagnoses were assessed using the Development and Well-Being Assessment (DAWBA) following DSM-IV criteria. The table summarizes lifetime psychiatric disorders identified in probands up to each wave. Phenotypes are counted from the wave of first identification onward.

5.4 Diagnosis Timing Relative to miRNA Acquisition

A diagnosis is counted by acquisition when identified in the same or an earlier wave. Age-18+ diagnoses use p1dawbaage or sdawbaage.

Exclusions

Pre-18-only cases and diagnoses first observed after acquisition are excluded from controls. Participants without an age-18+ evaluation fall outside the adult denominator.

Psychiatric Diagnosis Timing Among Probands with miRNA (Jessica) Data (BHRC)
Cell format: cases / controls / excluded lifetime cases
Psychiatric Phenotype	Lifetime (N=120)	Diagnosed at 18+ (N=117)	By miRNA (Jessica) wave (N=120)	At 18+ by miRNA (Jessica) wave (N=56)
ADHD	46 / 74 / 0	12 / 72 / 33	42 / 74 / 4	6 / 39 / 11
Anxiety Disorders	57 / 63 / 0	34 / 61 / 22	50 / 63 / 7	14 / 27 / 15
Bipolar Disorder or Mania	4 / 116 / 0	3 / 113 / 1	1 / 116 / 3	0 / 53 / 3
Eating Disorders	4 / 116 / 0	2 / 113 / 2	3 / 116 / 1	1 / 55 / 0
Major Depressive Disorder	57 / 63 / 0	35 / 61 / 21	53 / 63 / 4	24 / 22 / 10
OCD	8 / 112 / 0	4 / 109 / 4	6 / 112 / 2	1 / 52 / 3
Psychosis	3 / 117 / 0	2 / 114 / 1	3 / 117 / 0	2 / 53 / 1
PTSD	16 / 104 / 0	7 / 101 / 9	10 / 104 / 6	1 / 49 / 6
Any Psychiatric Disorder	102 / 18 / 0	66 / 17 / 34	98 / 18 / 4	34 / 5 / 17
Cells show cases / controls / excluded cases. Controls were assessed and never positive. Pre-18-only cases are excluded from adult controls; 3 participants lacked an age-18+ evaluation. Diagnoses first observed after the relevant miRNA (Jessica) wave are excluded from acquisition-aligned controls.
