MOODS-SR. A post-hoc analysis was conducted for the 33-items
subset of the MOODS-SR.
Results
The subset showed high internal consistency (Cron-
bach = 0.95). The mean scores of patients with bipolar disorder
(22.7
±
6.4) were significantly higher than those of the unipolar
(11.3
±
4.9) and control group (7.0
±
7.0,
P
< 0.005). A significant
correlation was found between YMRS (
r
= 0.50,
P
< 0.005) and the
33-item subset, but not with MADRS (
r
= –0.22,
P
= 0.223).
Conclusion
The 33-item subset of MOODS-SR showed promising
psychometric properties, including good known-group validity. It
discriminated bipolar patients from unipolar patients and healthy
subjects. The clinical usefulness of these finding needs further
investigation.

Objective
To examine the impact of appearance comparison
behaviours, trait body dissatisfaction and eating pathology on
women’s state body dissatisfaction and engagement in disordered
eating behaviours in daily life.
Method
Using ecological sampling method (ESM), 116 women
residing in Australia, completed a baseline questionnaire contain-
ing the trait-based measures, before being signalled by an iPhone
app six times daily, for seven days, to self-report on their recent
appearance comparison behaviours, current state body dissatisfac-
tion and recent disordered eating behaviours.
Results
Multi-level modelling revealed that upward compar-
isons (comparisons against more attractive individuals) elicited
increases in state body dissatisfaction ( = 0.89,
P
< .001) and
disordered eating behaviours ( = 0.29,
P
= .002). Contrastingly,
downward comparisons (comparisons against less attractive indi-
viduals) elicited decreases in state body dissatisfaction ( = –0.31,
P
= .048) and, unexpectedly, increases in disordered eating
behaviours ( = 0.46,
P
< .01). The frequency of appearance com-
parison engagement, regardless of whether it was upward or
downward comparisons, was also predictive of increased disor-
dered eating behaviours ( = 0.12,
P
< .001). In addition, eating
pathology and trait body dissatisfaction were directly associated
with higher state body dissatisfaction, and increased in disordered
eating behaviours (all
P
< .001).
Conclusion
These findings highlight the general negative impact
that appearance comparisons have on fluctuating states of body
dissatisfaction and eating pathology, as well as illustrating how
trait characteristics partially account for this volatility. These find-
ings provide further information that may be used to inform eating
disorder prevention and intervention efforts.

Introduction
Disgust propensity (DP) and disgust sensitivity (DS)
contribute to individual differences in the experience of disgust.
Studies have shown that DP and DS are predictive of some anx-
iety (e.g., spider phobia and blood-injection-injury phobia) and
obsessive-compulsive and related disorders.
Aim
The aim of this study was to develop and validate a
Portuguese version of the Disgust Propensity and Sensitivity
Scale-Revised (DPSS-R; van Overveld= et al., 2006) for use in
Portuguese-speaking populations.
Method
Two hundred and six participants (162 females), with
ages between 18 and 47 (M= 25.92; SD = 8.75), filled in the DPSS-R,
whichwas first translated and adapted into Portuguese language by
individuals highly proficient in English and then back-translated by
a bilingual with no prior knowledge of the scale. Finally, the DPSS-R
was subjected to a think-aloud procedure.
Results
The results showed good internal consistency (Cron-
bach’s alfa = .833) for a DPSS-R. The two subscales displayed an
adequate internal consistency (DP
Cronbach s alfa
= .776; DS
Cronbach s
alfa
= .790). Test-retest analysis documented good intraclass cor-
relation coefficient for the two subscales (ICC
Propensity
= .889; ICC
Sensitivity
= .900). We also confirmed the bifactorial structure using
a confirmatory factor analysis, since we obtained appropriate val-
ues in all goodness of fit indices (
2
df = 1,906; CFI = .94; PCFI = .736;
GFI = .93; PGFI = .607; RMSEA = .067).
Conclusion
DPSS-R obtained good psychometric properties and
may therefore be proposed as a valid instrument to assess DS and
DP in the Portuguese population. This instrument may provide an
important contribute to study the development and maintenance
of psychopathology associated with disgust.
