Exclusion Criteria: Parents of children with cancer will be excluded if (1) they do not read or speak English or Spanish; (2) their child is in severe a medical crisis, as determined by the oncologist, or (3) they live a prohibitive distance to complete the intervention (typically, >50 miles from the Center) and do not have access to a telephone for phone intervention sessions. Internet access will be facilitated as part of the e-PSST intervention arm. These exclusionary criteria are identical to our previous work; <10% of eligible mothers have been excluded.
