abstract
Pre-pregnancy maladaptive eating behaviors have predicted inadequate or excess gestational weight
gain and poor dietary intake during pregnancy, but little is known about effects of pre-pregnancy
adaptive eating behaviors on pregnancy outcomes. The purpose of this study was to produce a valid
and reliable measure of adaptive pre-pregnancy eating behaviors for pregnant women using the Intuitive
Eating Scale. Data were collected from 266 pregnant women, aged 18 and older who were attending a
private prenatal clinic at Texas Children's Hospital Pavilion for Women in Houston, TX using self-
administered questionnaires. Confirmatory factor analysis was performed to validate the factor struc-
ture of the Intuitive Easting Scale (IES). Concurrent validity was determined using correlations between
the three subscale scores [unconditional permission to eat (UPE), eating for physical not emotional
reasons (EPR), and relying on hunger/satiety cues (RIH)], perinatal depression status (Edinburgh Post-
natal Depression Scale), and pre-pregnancy body mass index (BMI) calculated from self-reported height
and weight. After discarding 6 items, the second order model did not fit the data, however, the first order
model with three latent factors had reasonable fit (RMSEA ¼ 0.097, CFI ¼ 0.961, TLI ¼ 0.951 and
WRMR ¼ 1.21). The internal consistency of the scale was confirmed by Cronbach's alphas (UPE ¼ 0.781,
EPR ¼ 0.878 and RIH ¼ 0.786). All subscale scores were inversely related to perinatal depression status.
EPR and RIH subscale scores were inversely related to pre-pregnancy BMI, supporting the measure's
validity. Among pregnant women, the revised 15 item pre-pregnancy IES (IES-PreP) should be used to
evaluate pre-pregnancy adaptive eating behaviors.

1. Introduction
The Institute of Medicine, Gestational weight gain (GWG) rec-
ommendations for pregnancy is based on the pre-pregnancy body
mass index (BMI). Women who are normal weight prior to preg-
nancy are recommended to gain 11.5e16 kg, the recommendation
for overweight women is 7e11.5 kg and for obese women it is
5e9 kg. Inadequate and Excessive GWG are used to describe weight
gain below and above this recommendation respectively. Excess
GWG and poor dietary intake are related to adverse health out-
comes including postpartum weight retention, gestational
diabetes, pregnancy induced hypertension, pre term deliveries,
fetal growth restriction, fetal macrosomia, large for gestational age
infants, neonatal hypoglycemia, and infant and childhood obesity
(Dietrich, Federbusch, Grellmann, Villringer, & Horstmann, 2014;
Grieger, Grzeskowiak, & Clifton, 2014; Margerison Zilko, Rehkopf
& Abrams, 2010; Thangaratinam et al., 2012). According to
2012e2013 United States data, prevalence of inadequate GWG
ranged from 12.6% to 25.5% and prevalence of excessive GWG
ranged from 38.2% to 54.7%, while only 32.1% of women had
adequate weight gain according to Institute of Medicine recom-
mendations (Deputy, Sharma, & Kim, 2015). Additionally, a recent
study showed that on average, pregnant women do not adequately
conform to federal dietary guidelines (United States Department of
Agriculture (USDA) Center for Nutrition Policy Promotion
Promotion, 1995) with 40% of pregnant women not meeting the
minimum recommended number of servings of most food groups,
dietary fiber, calcium, vitamin D, iron and folate (Pick, Edwards,
