Article Critique
Trinh, L., Amireault, S., Lacombe, J., & Sabiston, C. M. (2015). Physical and psychological
health among breast cancer survivors: interactions with sedentary behavior and
physical activity. Psycho‐Oncology, 24(10), 1279-1285.
Answers
1. The research aims at determining the interactive association between sedentary behavior
induced symptoms of fatigue, pain, and depression, and its effect by light and
moderate-to-vigorous levels of physical activity among the breast cancer survivors.
2. The researchers hypothesize that sedentary behavior is associated with the introduction of
late-effect symptoms such as depression, fatigue and pain in survivors of breast
cancer, and low levels of sedentary behaviors coupled with high levels of physical
activity will negatively affect the symptoms.
3. The participants were breast cancer survivors and were recruited with the help of local
printed advertisements and referrals from oncologists in local hospitals and medical
clinics. Inclusion criteria for the participants were breast cancer survivors above the
age of 18 years, with knowledge of French or English language, have completed
primary treatment in the last 20 weeks, and diagnosed with breast cancer of stage I-
III. Exclusion criteria included cancer diagnosis more than one, metastatic disease and
health concerns, which were self-reported and prevented the women from
participating in physical activity.
4. The participants that were recruited were part of a longitudinal study ‘Life After Breast
Cancer: Moving On.’ The study explored the life-style and behavioral, developmental
changes post 3 to 4 months of post-systematic treatment. The researchers choose an
experimental study design to achieve the objectives of the study.

5. It is a basic or fundamental type of research that aims at expanding knowledge on the
association of sedentary behavior and its induced symptoms impacted by different
levels of physical activity. The research has no immediate commercial objective and
cannot be classified as applied research.
6. The independent variables were levels of sedentary behavior and levels of physical activity
ranging from low to vigorous. The dependent variables were the symptoms of
depression, fatigue, and pain in the subject samples and their prevalence levels. The
independent variables were assessed with the help of the GT3X accelerometer. The
dependent variable of pain was assessed with self-report of acknowledgment from the
participant, fatigue symptom was assessed with the help of POMS (Profile of Mood
States), and depression was assessed with the help of CES-D10 (Center for
Epidemiological Studies Depression Scale).
7. The activity levels of the participants during walking were noted down for seven
consecutive days with the help of the accelerometer that they wore while walking.
Daily minutes of physical activity was categorized into light, moderate, and vigorous
amounts of physical activity. Sixty minutes of consecutive zeros were counted as
sedimentary time.
8. The research findings concluded that around 72% of the breast cancer survivors
(participants), failed to meet the public physical activity guidelines. Increase in the
levels of moderate to vigorous levels of physical activity (r= -0.43) was significantly
correlated to a lower level of sedimentary behavior (p<0.01) with positive inter-
correlation with depression, fatigue and pain. A lower level of physical activity is
correlated with an increase in sedimentary behavior and showed an increase in the
symptoms of fatigue (p=.01; ΔR2=0.04), pain (p=.02; ΔR2=0.03), and depression in
the breast cancer survivors (p=.006; ΔR2=0.04).
