Limitations of this study include the following. First, the absence of a control group means it is not possible to determine the effect of the treatment beyond that of spontaneous remission. Second, despite the small sample size being less than ideal, statistically and clinically significant improvements in symptom levels were found, however an increased sample size would improve the accuracy and robustness of the symptom change estimation. Third, the small sample size limits the extent to which the results can be generalised and means that significant caution is needed in interpreting the results of the trial beyond conclusions about the general feasibility of iCBT for Arabs in Australia. Fourth, the relatively high educational level of the sample limits the extent to which the results can be generalised to those with lower levels of educational attainment. Fifth, the level of acculturation was not measured raising questions about the extent to which acculturation may moderate treatment outcomes. However, a large randomised controlled trial is planned, which will address several of these issues.
