Internal validity
the extent to which the interpretations drawn from the results of a study can be justified and alternative interpretations can be reasonably ruled out
Threats to validity
History
Maturation
Testing
Instrumentation
Statistical regression
Selection bias
Attrition
External validity

8. Participants selection & assignment
Sampling
Optimize the fit between characteristics of the population to which the results will be generalized
The type of sample that should be recruited
The number of participants required for the study
Statistical power

9. Measurement options Self-report measures Informant-report measures
Rater evaluations
Performance measures
Projective measures
Observation of behavior
Psychophisiological measures
Archiaval data

10. Psychometric properties of the measures
Reliability
Internal Consistency
The degree to which elements of the measure (such as items on a test) are homogeneous.
Test-Retest Reliability
The stability over time of scores on a measure.
Interrater Reliability
The consistency of scores on a measure across different raters or observers

11. Psychometric properties of the measures
Validity
Content Validity: The extent to which the measure fully and accurately represents all elements of the domain of the construct being assessed.
Face Validity: The extent to which the measure overtly appears to be measuring the construct of interest.
Criterion Validity: The association of a measure with some criterion of central relevance to the construct, such as differentiating between groups of research participants.
Concurrent Validity: The association of a measure with other relevant data measured at the same point in time.
Predictive Validity: The association of a measure with other relevant data measured at some future point in time.
Convergent Validity: The association between a measure and either other measures of the same construct or conceptually related constructs.
Discriminant Validity: The association between measures that, conceptually, should not be related.
Incremental Validity: The extent to which a measure adds to the prediction of a criterion beyond what can be predicted with other measurement data.

12. Significance Statistical vs clinical significance
the outcome of a study and the degree to which a research hypothesis was supported
evaluating the degree to which the intervention has had a meaningful impact on the functioning of the treated participants
