“…Although, this is comparable to the 23 and 14%, respectively, reported in a study of women during treatment for breast cancer [ 13 ], it is generally low compared to findings in studies that applied the TPB model in other types of cancer [ 7 , 24 , 25 , 43 , 45 ]. The current study confirms the relevance of social-cognitive constructs in explaining PA behavior in HNC survivors observed in previous research [ 35 , 37 ]. The low amount of variance in PA intention and behavior explained and the poor model fit indicate the need for better suitable or additional behavior theories to explain behavior in HNC survivors that can assist in developing interventions to promote PA behavior.…”

PurposeThe purpose of the study is to identify demographic, clinical, lifestyle-related, and social-cognitive correlates of physical activity (PA) intention and behavior in head and neck cancer (HNC) survivors using the theory of planned behavior (TPB).MethodsData from two cross-sectional studies on correlates of PA in HNC survivors were pooled. Both studies used self-reports to assess PA and social-cognitive correlates. Potential correlates were collected via self-report or medical records. Univariable and multivariable multilevel linear mixed-effects models were built to identify correlates of PA intention and PA behavior (Z scores). Structural equation model analyses were conducted to study the full TPB model in one analysis, taking into account relevant covariates.ResultsIn total, 416 HNC survivors were surveyed. Their mean (SD) age was 66.6 (9.4) years; 64% were men, and 78% were diagnosed with laryngeal cancer. The structural equation model showed that PA intention was significantly higher in HNC survivors with a history of exercising, who had a more positive attitude, subjective norm, and perceived behavioral control. Patients with higher PA intention, higher PBC, a lower age, and without unintentional weight loss or comorbidities had higher PA behavior. The model explained 22.9% of the variance in PA intention and 16.1% of the variance in PA behavior.ConclusionsDespite significant pathways of the TPB model, the large proportion variance in PA intention and behavior remaining unexplained suggests the need for better PA behavior (change) models to guide the development of PA promotion programs, particularly for the elderly. Such programs should be tailored to comorbidities and nutritional status.

“…Firstly, PA enjoyment has been measured with two items only. Although it has a good internal consistency and is based on a measure used in other oncological studies (e.g., Rogers et al, 2011 , 2015 ), a multi-item measure such as the PA enjoyment Scale (PACES; Kendzierski and DeCarlo, 1991 ) would be preferable and would allow more differentiated analysis. As PA enjoyment was compared to self-efficacy which was assessed much more in detail, our results might be affected by this unequal assessment methods.…”

Physical Activity Enjoyment and Self-Efficacy As Predictors of Cancer Patients' Physical Activity Level

Background: Physical activity (PA) can support cancer patients during medical treatment by reducing side-effects and increasing quality of life. However, PA levels mostly decline after diagnosis. Which factors can explain if patients are able to remain or even increase their PA level? Self-efficacy is an important cognitive factor that has been linked to cancer patients' PA across many studies. In contrast, affective factors such as PA enjoyment have rarely been examined. We compare the influence of self-efficacy and PA enjoyment on cancer patients' PA levels after completion of an exercise or stress-management intervention.Methods: Outpatient cancer patients [N = 72; 54% female; M = 56 years, SD = 12.34; most with breast or colon cancer (34%, 15%)] were enrolled in the MOTIVACTION study, a 4-week intervention (1 h counseling followed by weekly phone calls), with pre-test (T1), post-test (T2), and a 10-week follow-up (T3). Participants were randomized to either an exercise intervention (emphasizing self-regulatory strategies for behavior change) or to a stress management intervention (coping and relaxation techniques). Sixty-seven patients remained in the study and completed the SQUASH assessment of PA, a measure of maintenance self-efficacy (7 items, Cronbach's α = 0.88) and PA enjoyment (2 items, Cronbach's α = 0.89). Regression analyses were calculated with PA level (at T2 and T3) as dependent variable and relative weight analyses were conducted. The study was registered at clinicalTrials.gov (unique identifier:NCT01576107; URL: https://clinicaltrials.gov/ct2/show/NCT01576107?term=motivaction&rank=1).Results: Baseline self-efficacy and change in PA enjoyment significantly predicted cancer patients' PA level at T2 adjusting for baseline PA and type of intervention. Relative weight (RW) analysis revealed that PA enjoyment (baseline and change together) explained 34.3% of the dependent variable, self-efficacy (baseline and change) explained 38.4%. At follow-up, self-efficacy was still a significant predictor of PA (RW = 74.6%), whereas PA enjoyment was no longer a relevant factor (RW = 5.2%).Conclusion: The affective factor PA enjoyment was equally important as self-efficacy for predicting cancer patient' PA level directly after completion of the intervention. Reasons for the reduced relevance at follow-up and a broader range of affective factors should be analyzed in future studies on cancer patients' PA level.

“…Physical activity enjoyment. Physical activity enjoyment was measured at all three measurement points with two items based on Rogers et al (2011Rogers et al ( , 2015. The items were "It is fun to engage in sport activities and regular physical activity" and "I enjoy being regularly physically active" (from 1 = not true to 4 = completely true).…”

Worse or even better than expected? Outcome expectancies and behavioral experiences in the context of physical activity among cancer patients

et al. 2019

Expectancies of cancer patients regarding their physical activity before they took part in a behavior change intervention were compared with their experiences during the intervention period. A total of 66 cancer patients completed either a randomly assigned 4-week physical activity or a stress-management counseling intervention. On average, participants had positive expectancies toward physical activity. Outcome expectancies predicted outcomes (e.g. physical activity) at a 10-week follow-up. Outcome realization (discrepancy between expectancies and experiences) further increased explained variance in self-efficacy and physical activity enjoyment. In conclusion, not only initial outcome expectancies but also their realizations seem to be important for subsequent behavior and cognitions.
