Hello, I am currently working on finding antecedents of brand hate. I have put forth a construct that leads to brand hate. So, the antecedent which leads to brand hate has three different dimensions (Political, Economic, and Military). And brand hate is made up of three different emotions (Anger, Disgust, and Contempt).
Independent Variables (Antecedent)
- Treatment 1: Political
- Treatment 2: Economic
- Treatment 3: Military
- Treatment 4: Control
Dependent variable (Brand Hate)
- Anger
- Disgust
- Contempt
We are going to develop three different essays (scenario) that will represent each of the independent variables. And there will be a survey that will be filled by the participants after reading the scenario. Three different treatments will be given to different groups.
I would like to know the following:
Type of Experimental design?
Population?
Sample size?
Hypotheses type: Directional or Nondirectional?
Data collection: Random, Nonrandom? (the study will distribute the survey online)
Analysis?
And that whether if there is a need for a control group or not.
Thank you in advance, if there is any information which you believe is missing please message me and I would provide it. It would be very helpful if someone with experience in experimental research could message and guide me through this.
Thank you
With longitudinal analyses. You can see: Swoboda and Winters (2021), Reciprocity within major retail purchase channels and their effects on overall, offline and online loyalty, Journal of Business Research, 125, 279–294
One factorial (as you have one independent variable: Antecedent with different levels I presume) between-subjects design should work well.If you measure your dependent variable on Likert type scale ANOVA as analysis may serve well. You could also run Hayes PROCESS (with multi-categorical X).
For you to be able to generalize your results to a larger group it is important that you have a representative sample (here perhaps the population comprises of people who engage in emotional relationships with brands), a random assignment is useful for validity and generalizability of results.
You may benefit from sample size recommendations provided here:

This is the best explanation. Between-group is going to work the best in my option. I have already started my work with Between-group design where i have 3 conditions (treatment groups) from animosity dimensions and the dependent variable is brand hate. And for the outcomes brand hate becomes a mediating variable for animosity.
