The Short-Form PWBS was tested for internal consistency, construct validity, and
criterion-related validity. Results: Cronbach's alpha was 0.88, with aggregated subscale alphas of 0.72-0.88, except 0.57 for autonomy.
Predictive validity is a subtype of
criterion-related validity, where the criterion is a future test, i.e.
Criterion-related validity was split into concurrent and predictive, subject on the timing of the data collection for the criterion evidence.
The
criterion-related validity of the SMDS was examined by the use of compulsive internet, social media addiction, depression, self-esteem, loneliness, attention deficit, impulsivity and frequency of daily social media use.
While works detailing research methods organize the same types of validity in various ways, we adhered to Huck's (2008) conceptual framework of validity, which aligns methods of establishing validity with three overall types: content validity,
criterion-related validity, and construct validity.
The
criterion-related validity of the Rolefulness Scale is confirmed by examining its correlation with other psychological scales.
The correlation coefficient between each item and the total score of the remaining items ranged from .45 to .66, which indicated that the scale has reasonable
criterion-related validity.
In the second study, the COPE-Revised scores were tested against the self-esteem scores of a group of participants to examine both the internal psychometric properties and
criterion-related validity of the COPE-Revised.
Internal Consistency,
Criterion-Related Validity, and Construct Validity.
Similar to reliability, there are different types of validity that can be established when evaluating a tool, which include content validity,
criterion-related validity, construct validity, and factor analysis (Polit & Beck, 2016).
We will also explore the psychometric properties of the questionnaire, in terms of reliability and
criterion-related validity.
Criterion-related validity and nomological validity were assessed relating past, present and future life satisfaction with life with the aforementioned criteria, both with traditional correlations and also within a structural equation modeling.
