This study was funded through an Outcomes Research Service
Agreement with Pfizer, Inc.; the primary purpose of this Agree-
ment was to assess the feasibility, acceptability, and reliability
of e/Tablets as a method for collecting patient-reported data in
the academic oncology setting. Pfizer does not have access to
individual data. SOS, Inc. served as vendor in this project; the
vendor provided the hardware, which was not funded through
the Pfizer agreement. Duke University Medical Center pro-
vided the wireless system and associated technical support.
Dr. Abernethy has a consulting arrangement with SOS, Inc.,
which was reported to the Duke University Internal Review
Board and Conflict of Interest Committee; there are no other
conflicts to be disclosed.

Abstract Notebook-style computers (e/Tablets) are increasingly re-
placing paper methods for collecting patient-reported information.
Discrepancies in data between these methods have been found in oncol-
ogy for sexuality-related questions. A study was performed to formulate
hypotheses regarding causes for discrepant responses and to analyze
whether electronic data collection adds value over paper-based meth-
ods when collecting data on sensitive topics. A total of 56 breast cancer
patients visiting Duke Breast Clinic (North Carolina) participated by re-
sponding to 12 subscales of 5 survey instruments in electronic (e/Tablet)
format and to a paper version of 1 of these surveys, at each visit. Twenty-
one participants (38%) provided dissimilar responses on paper and
electronic surveys to one item of the Functional Assessment of Cancer
Therapy–General (FACT–G) Social Well-Being scale that asked patients to
rate their satisfaction with their current sex life. Among these 21 patients
were 8 patients who answered the question in the electronic environ-
ment, and 13 patients who answered both paper and electronic versions
but with diferent responses. Eleven patients (29%) did not respond to
the item on either e/Tablet or paper; 45 patients (80%) answered it on
e/Tablet; and 37 patients (66%) responded on the paper version. The e/
Tablet electronic system may provide a “safer” environment than paper
questionnaires for cancer patients to answer private or highly personal
questions on sensitive topics such as sexuality.
P
atient-reported survey data are becom-
ing increasingly recognized as an impor-
tant component of clinical research and
patient care, but the sensitive nature of
certain topics introduces challenges into the col-
lection of patient-reported information. Most no-
tably, sexuality-related questions introduce limi-
tations into research due to their sensitivity and
perceived invasiveness. In responding to surveys,
participants may hesitate to ask for clarification
if they do not understand a question; may be re-
luctant to proffer information that they consider
highly personal and inherently private; may feel
uncomfortable responding to personal questions
in the presence of a spouse, caregiver, or clini-
cian; and may experience discomfort in discuss-
ing sexuality-related questions with researchers
and clinicians.

Unless the privacy of responses
to sexuality-related questions can be ensured, pa-
tients may be unwilling to participate in research
that solicits such intimate information; a self-
selection factor in study populations may there-
fore compromise the validity and usefulness of
research data.
Previous studies requesting sensitive informa-
tion have cited small sample sizes due to high par-
ticipant refusal rates. For example, in a study of
chronic pain and sexuality, Monga et al reported
that only 40% of approached patients participated
in the study, of which 12 (7%) were excluded from
the final analysis because they did not respond
to questions regarding sexual function.

Addi-
tional methodologic problems plaguing research
concerning sexuality include limited capacity for
external validation and questionable accuracy of
responses, which could be biased, for instance, by
participants’ tendency to provide socially desir-
able responses.
