| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | "Research participants were randomly assigned..." (p.162) Method of randomisation not specified, however |
| Allocation concealment (selection bias) | Unclear risk | No information specified |
| Blinding (performance bias and detection bias) Subjects | High risk | The nature of the trial suggests it is unlikely participants could have remained blind to the fact they were allocated to a no treatment control group. However, without access to the participant information sheets and PLS, level of blinding cannot be ascertained. |
| Blinding (performance bias and detection bias) Assessors | Unclear risk | All outcomes self‐reported. Assessor blinding therefore not applicable. |
| Incomplete outcome data (attrition bias) All outcomes | High risk | Proportion of participants with incomplete post‐intervention self‐reported depression scores: 15.63% Means and SDs used in meta‐analysis based on what data: observed cases Intention‐to‐treat analyses: not undertaken |
| Selective reporting (reporting bias) | Unclear risk | Protocol not available |
| Other bias | High risk | Trial conducted by those who developed the intervention |
| Implementation integrity | Unclear risk | Implementation integrity assessed: unclear if assessed Implementation integrity adequate: N/A Implementation integrity reported: N/A |
