Hi, I'm not sure if it is suitable to use One Way Repeated Measure ANOVA for my research. My research's purpose is to see if online mindfulness intervention is effective in improving subjective well-being (SWB) and quality of life (QOL) of university staff. The situation here is, I have collected data through questionnaire at 4-time points (T1, T2, T3, T4). After T4, only 31 (n=31) subjects remained with the study. The questionnaire contains items about mindfulness, SWB, and QOL. Meanwhile, the subjects were receiving treatments through online mindfulness intervention. So, I want to analyze if the intervention is really effective by comparing their mindfulness, SWB, and QOL scores at T2, T3, and T4 with the score at T1.
Hello Wan Nur Khairunnisa Ismail Based on your explanation, I do not see any problem in performing One Way Repeated Measure ANOVA analysis.
Thank you for your response Abolfazl Ghoodjani Stephen David Edwards Andrew Paul McKenzie Pegman
Yes, you can. To know the effect size, you can consider a mixed-effect linear model.
