Clinics use the four-item PHQ-4 (Kroenke et al., 2009) as a ultra-brief anxiety-depression screen before longer PHQ-9 or GAD-7 forms. The Quiz Hub extended those themes into 22 original frequency items with domain bars and a fear-of-intimacy stack for self-reflection, not a licensed clinical instrument.

Sample items mirror PHQ-2 mood stems and GAD-2 worry stems without copying official wording verbatim. Pair with our anxiety and depression quiz or browse the mental health and clinical hub.
