For testing the external construct validity of the scale, the correlation between the BQc-t results and NPAD, MNDI, and SF-36 was analyzed before and after treatment.' (12-141) Correlation coefficients of 1.00-0.91 were regarded as perfect, 0.90-0.71 as good, 0.70-0.51 as moderate, 0.50-0.31 as acceptable, and <0.30 as weak.' (16,17]) In the comparison between the scales, the questions matched for meaning during the previous studies were used.' (4,6]) For testing the external longitudinal construct validity, the differences of every item on the BQc-t and of the total scores in the corresponding subscales and the total scores in the other scales for pre- and post-treatment evaluations were calculated, and the significance of each difference and its level of correlation was interpreted.
- External construct validity: The Question 7 of the NPAD and Part 8 of the MNDI were found to be left blank by the patients who did not drive as anticipated.
- External longitudinal construct validity: Based on the data obtained by matching the relevant subscales of the NPAD and MNDI with the items on the BQc-t before and after treatment, except for Question 7, a weak, moderately positive, statistically significant correlation was found.
The ES and SRM values of the BQc-t were higher than those of the NPAD and MNDI (Table 7).
In the wake of the ruling, neither Park nor the NPAD
chief Moon nor the then sitting President Lee Myung-bak have yet to comment on the ruling, and rightly so as we wait for the highest court's final say.
Min Hyun-joo, spokeswoman of the governing camp, said, "The NPAD labeled Kwon as a symbol of justice, but now it turns out that nominating her was a terrible decision."
The ruling party argued that the NPAD's decision to nominate Kwon was a sort of "compensation" for Kwon's actions last year during the parliamentary investigation that centered on the NIS scandal.
Sim Sang-jeung, floor leader of the minor opposition Justice Party, argued: "If the NPAD keeps protecting Kwon, it will become a moral hazard for the party.
