Table 2 Distribution of Dose Delivered in the Intervention Group (n = 304). The intended dose of the intensive phase was 12 weekly sessions, completed either by a face-to-face session or an alternative session (e.g., phone call). The intended dose of the maintenance phase was 9 monthly phone calls. Dose delivered is presented as the mean (standard deviation) number of sessions each parent-child pair received. Participants in the control group (n = 306) received zero dose and their data is not included in this table

  1. a Approximate contact hours calculated based on the following assumptions: intensive face-to-face sessions were 1.5 h, intensive alternative sessions were 0.42 h (25 min), and maintenance phone calls were 0.75 h. Approximate contact hours for total intensive sessions is based on the preceding assumptions as applied to the particular combination of face-to-face and alternative sessions completed by each individual participant pair
