Introduction The postpartum depression screening scale (PDSS;
Beck & Gable, 2002) is a widely used measure to assess women’s
depressive symptoms after their children’s birth. Pereira et al.
adapted, validated and developed a short-version of PDSS for Por-
tuguese women (PDSS-21).
Objective To examine the factor structure of the PDSS–21, using
confirmatory factor analysis (CFA) in a sample of Portuguese
women in the postpartum period.
Methods The sample was composed of 208 women (mean
age = 32.72; SD = 4.49) who completed the PDSS–21 approximately
at the 6th week postpartum. CFA was used to test the model sug-
gested by prior exploratory factor analyses of PDSS–21. AMOS
software was used.
Results After two items were deleted and some errors were
correlated, CFA indicated a good fit for the second-order
factor ( 2/df = 1.793; CFI = 0.957; GFI = 0.889, rmsea = 0.062; P
[rmsea ≤ 0.05] < 0.056). The 19–item PDSS showed excellent inter-
nal consistency ( = 0.92) and the four dimensions presented
Cronbach’s alphas ranging between good ( = 0.83) and excellent
( = 0.93).
Conclusions These findings suggest that the 19–item PDSS
obtained through CFA is a reliable and valid measure to assess
depressive symptoms among women in the postpartum period.

depression

Experiential avoidance, considered a main process of psychological
inflexibility, has been defined as the unwillingness to be in con-
tact with particular unwanted inner experiences and the effort to
control or avoid its form, frequency and the context in which they
occur. On the other hand, decentering, conceptualized as the abil-
ity to deal with feelings, thoughts and emotions as subjective and
ephemeral events, which occur in themind, is considered an impor-
tant protective process against psychopathology. The present study
aimed to explore the moderator effect of two different emotional
regulation processes, decentering and experiential avoidance, on
the association between external shame and depression. The sam-
ple comprised 421 participants (131 males and 290 females), aged
between 18 and 34-year-old. Results from two independent path
analysis revealed that decentering abilities and experiential avoid-
ance showed a significant moderator effect on the association
between external shame and symptoms of depression. In fact,
these findings allow to verify that decentering abilities were nega-
tively linked to symptoms of depression. Through a path analysis,
the buffer effect of decentering was confirmed. On the contrary,
performed tests demonstrated that experiential avoidance exac-
erbates shame’s impact on the severity of depressive symptoms.
Taken together, these findings emphasize the importance of target-
ingmaladaptive emotion regulation processes (such as experiential
avoidance), and developing adaptive strategies (e.g., decentering
abilities), as strategies to diminish depressive symptomatology in
prevention and intervention programs.

Shame and depression: The roles of
self-reassurance and social safeness

Self-reassurance and social safeness are both positive factors linked
with a lighter experience of shame and depression symptoms.
Self-reassurance is defined as an adaptive emotion regulation
process, and social safeness as an emotion experience related
to feelings of being safe around others, accepted by others, and
connected to one’s social world. Nevertheless, data about how
self-reassurance and social safeness and pleasure operate in the
association between external shame and depression is still scarce.
A path model which hypothesised that self-reassurance and social
safeness and pleasure may act as mediators on the association
between shame and depressive symptomatology was tested. This
study’s sample consisted of adultmen (n = 54) andwomen (n = 125),
from the Portuguese general population. Results indicated that
self-reassurance and social safeness act as mediators in the rela-
tionship between shame and depression symptoms. Specifically, a
higher report of shame seems to explain higher levels of depres-
sive symptomatology, via lower tendency for self-reassurance and
poorer experience of social safeness. The tested model explained
45% of the variance of depressive symptomatology and was
revealed to be invariant between men and women. This study’s
results underline the profound impact of the experience of com-
fort within secure and warm social relationships, but mostly the
importance of self-soothing and self-compassion abilities which
associate with greater social functioning. Moreover, in practical
terms, these findings reinforce the pertinence of cultivating self-
compassion, which has proven to be particularly relevant when
intervening with high levels of shame, and in the prevention of
depression.

Background Despite its high effectiveness, electroconvulsive
therapy (ECT) is not a widely used method to treat depression. One
of the reasons for this could be the fear of cognitive side effects.
The aim of this study was to investigate effects of ECT on cognitive
function.
