Supplementary course information
The course content deals with modern approaches for modeling treatment effects in multi-wave treatment/intervention studies. The course highlights key dilemmas and data analytic decisions from a user perspective.
The course objective is to provide a learning situation where participants gain experience with data management, key analytic decisions, and proper interpretations of results from longitudinal treatment/intervention studies. Topic include:
- Data management and data quality assurance in treatment/intervention studies
- Longitudinal data analysis
- Mixed-linear models of treatment/intervention effects
- Multilevel model of change in treatment/intervention studies
- Sample size, power and effect size
- Missing data assumptions, intention-to-treat analysis
- The complete workflow of longitudinal data analysis: Case studies
The 3-day course will be structured as a series of lectures (12-15 hs), lab sessions (6hs) and self-study (24hs) with relevant exercises. Participant are expected to bring their own laptop with SPSS installed.
The workshops include analysis of didactic data sets, but participants are encouraged to bring in their own datasets.
