Limitations of the study
The study had several limitations. There was no long-term follow-up beyond one month to assess the sustained effect of ACT on work-family conflict, work-related psychological flexibility, and social adjustment. Individual differences, such as personality traits, cultural factors, and prior experiences, were not assessed in relation to the effectiveness of ACT interventions. Lack of control was another limitation in the present study, as intern nurses may not adhere to the intervention as strictly as they would in an in-person setting, which could affect the validity of the results and limit the ability to draw conclusions about the effectiveness of the intervention. Uncontrolled contamination between the study and control groups due to participants meeting each other during their shifts could affect the validity of the results. The presence of baseline differences between the groups indicates that the randomization process may not have been completely successful. As a result, it may be challenging to draw accurate conclusions about the efficacy of the intervention. Excluding participants who did not complete the intervention introduced biases and limited generalizability. Future studies could consider more rigorous randomization procedures and collecting more detailed baseline information to address these limitations.
