There was no significant relationship between HADS-D and age
(r=–0.031; P=0.569). Duration of infertility was significantly associated
with depression at the 0.10 level, but the correlation was small in
magnitude (r = 0.097; P = 0.079). HADS-D scores did not differ by
sex (P = 0.890), cause of infertility (P = 0.307), or history of abortion(P = 0.397) (Table 3). However, patients who had an academic education
obtained significantly lower scores than did those who had a nonacademic
education (P b 0.001). Score on the HADS-D questionnaire
varied by age, although the difference was not significant at the 0.05
level (P = 0.055). By contrast with HADS-A, the mean depression
score was greatest among patients who had experienced two infertility
treatment failures (Fig. 1, Table 3).
In themultiple linear regression analysis for HADS-D, patientswith a
high level of education obtained significantly lower HADS-D scores than
did those with a low level of education (P b 0.001), and patients with
two infertility treatment failures obtained significantly higher scores
than did those without a history of treatment on the HADS-D
(P=0.019) (Table 4).
