From: Effect of reduced formal care availability on formal/informal care patterns and caregiver health: a quasi-experimental study using the Japanese long-term care insurance reform

Poor self-rated health (%) Symptoms of a depressive state (%) Symptoms of musculoskeletal diseases (%)

  1. DID: difference-in-differences. aWe analyzed the propensity score matched sample of 12,761 caregivers using an ordinary least squares regression with prefecture-level clustered standard errors. We showed the coefficient β2s multiplied by 100, which showed by how many percentage points the long-term care insurance reform in 2006 increased the percentage of experiencing the outcomes (Null hypothesis: coefficient = 0)
