--* Reliability: The evaluation is reliable. One could replicate the same experiment with other patients.
--* Validity: This evaluation is not really valid. Our feasible evaluation does not have the corresponding target group, and is of a much smaller scope compared to our ideal evaluation. We cannot test all our claims.
--* Biases: The evaluation has large biases. This is discussed more in detail in the limitations where the different bias factors are explained.
--* Scope: The evaluation can be generalized to a larger scope, although with a lot of care, since the evaluation is not fully valid.
--* Ecological validity: The evaluation is partially valid in terms of influence from the environment. The affect assessment questionnaire is the same before the activity and after, with the same environment, so the environment is technically not involved in this. However, the system assessment questionnaire does rely on some elements from the environment.
++* Reliability: Yes. One could replicate the same experiment with other patients.
++* Validity: TBD.
++* Biases: TBD.
++* Scope: No. It would be very difficult to generalize the results, since each prototype is built for a special patient. However, if the results conclude that the customized prototypes did improve the well-being of the people, then similar effort to customize Pepper for more patients should produce similar effects.
++* Ecological validity: Yes. Since we compare "without Pepper" (BEFORE) and "with Pepper" (AFTER) in a similar environment (i.e., for everything but Pepper), the results are not dependent on the environment.
--**Affect assessment questionnaire**
++**mood questionnaire**
  We analyzed the participants' moods before and after the interaction with Pepper in order to be able to observe positive and negative changes that are caused by the interaction with Pepper. the results showed that, in general, there is a slight increase in positive moods and a slight decrease in negative moods. The Wilcoxon Signed-rank demonstrated that the only statistically significant change happened for contentness and tiredness based on a p-value threshold of 0.05.
