An assessment of the psychometric properties of the Coping Strategies Questionnaire – Sickle Cell Disease (CSQ-SCD) among adults in the United States

Table 4 Discriminant validity (i.e., tests of perfect correlations) assessed by Wald’s Chi-square test

Model^a (correlation fixed to 1)	Wald’s Chi-square Value	DF	P-value
Active coping with affective coping	66.264	1	< 0.001
Affective coping with passive adherence coping	45.958	1	< 0.001
Active coping with passive adherence coping	14.858	1	< 0.001

^aModel was compared to base model with no restrictions on correlation between factors – i.e., correlations were freely estimated; significant tests indicate that the factors are not perfectly correlated, providing evidence of discriminant validity. DF, degrees of freedom
