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.
