reliability was assessed using polychoric correlation - based version of the
reliability coefficients.45 These analyses suggested satisfactory internal
consistency for the SDQ total difficulties scale (α = 0.86) and for all subscales (α emotional problems = 0.82, conduct problems = 0.71, hyperactivity — inattention = 0.76, peer problems = 0.75 and prosocial behaviours = 0.77).

consistency for both Intensity (α = 0.98, α = 0.95) and Problem scales (α = 0.96, α = 0.93).54
Reliability coefficients at 12 - week intervals for SESBI - R and ECBI Intensity (r = 0.94 and r = 0.80) and Problem scales (r = 0.98 and r = 0.85) are also high.54 A reduction in score indicates fewer and / or less problematic disruptive behaviours.

Previous studies have found TCSQ to have high
reliability and validity as a measure of coping style in China.49 50 In this study, Cronbach's α for the total scale was 0.845, and the internal
consistency coefficients of the subscales were α = 0.823 (positive coping) and α = 0.863 (negative coping).
We use SPSS18.0 to analyze the
reliability and validity of the questionnaire, and the result shows that all variables» Cronbach's alpha
coefficient is above 0.7, which suggests the internal
consistency of the variables is good, and the scales have a high
reliability.
Alpha
coefficients of (
reliability) questions about the subscales of secure, avoidant and ambivalent attachment styles regarding a student sample (1480 people) were calculated to be respectively 0.86, 0.84 and 0.85 for all the subjects, which indicate good internal
consistency of Adult Attachment Scale.
The
consistency coefficients ranged from 0.75 to 0.90;
reliability was highest regarding «affective well - being» and lowest regarding the coping subscales.
In phase II, internal
consistency of the Urdu translated version of PLS was determined through test re-test
reliability / cross language validation, Cronbach's alpha
reliability coefficient and item total correlation.
Results indicated the good level of internal
consistency in form of Cronbach's alpha

Like the STAI trait, the CES - D is a reliable assessment with alpha
coefficients of internal
consistency ranging from.80 to.90 and a 2 - week to 1 - year test — retest
