Interventions | 56 participants allocated to one of two groups
Attendance: 62% of parents attended eight sessions, 62% attended six or more sessions. The children's attendance in the SST group was not reported; seven children (12.5%) discontinued the study (five from group one (medication + behaviour therapy) and two from group two (medication alone)). |

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Comment: clarification requested from one of the study investigators and Dan Waschbusch informed us in an email on 22 June 2011 that they had used a computer‐generated randomisation process (Waschbusch 2011 [pers comm]). |
Allocation concealment (selection bias) | Low risk | Comment: clarification requested from one of the study investigators and Dan Waschbusch informed us in an email on 22 June 2011 that the clinicians did not know the treatment assignment before it was assigned (Waschbusch 2011 [pers comm]). |
Blinding of participants and personnel (performance bias) All outcomes | High risk | Comment: no blinding |
Blinding of outcome assessment (detection bias) All outcomes | High risk | Comment: no blinding |
Incomplete outcome data (attrition bias) All outcomes | High risk | Comment: We requested clarification from one of the study investigators and Dan Wascbusch informed us in an email that participants were dropped if there was not sufficient information. Scores in indexes were computed if at least 50% of the items in the index were answered; if not, they were counted as missing. Dan Wascbusch also informed us that they had essentially complete data at pre‐treatment and nearly complete data at post‐treatment. They had a lower response rate for teachers. They included whatever they had in the analyses and dropped participants when there was insufficient information, repeating this for each analysis (Waschbusch 2011 [pers comm] |
Selective reporting (reporting bias) | High risk | Comment: protocol published in Clinicaltrials.gov after study had been conducted. Publication was not consistent with the report in Clinicaltrials.gov |
Vested interest bias | High risk | Comment: funding from, and collaboration with, Eli‐Lilly |
Other sources of bias? | Unclear risk | Comment: co‐medication not specified |
