The rates of secure (B) and insecure (A, C
and D) attachment were similar for all four
groups and no significant differences were
found between the treated groups and the
control condition (see Table 2). After
controlling for social adversity, the
treatment effects remained insignificant.
Cognitive development
At 18 months post-partum, scores on the
measure of child cognitive development,
the Mental Development Index of the
Bayley Scales (see Table 4), were similar
for the four groups (Kruskal–Wallis¼
0.78; d.f.¼3; P¼0.85). A generalised linear
model, which assumed that the scores
followed a gamma distribution, revealed
there to be no significant treatment effects
after controlling for social adversity and
the significant adverse effects of young
maternal age (w2¼6.13; d.f.¼1; P¼0.01),
low maternal education (w2¼7.67; d.f.¼1;
P¼0.006) and male gender (w2¼7.73;
d.f.¼1; P¼0.005).
