The role of dysfunctional schemas and acceptance regarding chronic fatigue in oncology patients after treatment
This scientific cross-sectional study is at the intersection of medical psychology and oncology and will address the role of dysfunctional schemas and acceptance in the development of fatigue symptoms after treatment for cancer.
Cancer is potentially a deadly disease, but early detection and modern available treatments have increased survival rates in recent decades. Increasing attention is being paid to the well-being of survivors. One of the side effects of long-term curative treatment of cancer, is chronic fatigue. Fatigue has a major impact on daily life and thus on the patient's quality of life.
This study deals with patients who still suffer from chronic fatigue 6 months to two years after (intentionally curative) cancer treatment. Defined in English as chronic cancer-related fatigue (CCRF). The role of acceptance and dysfunctional schedules in maintaining chronic fatigue after cancer will be investigated.
The question is whether oncology patients with dysfunctional schedules after treatment are more likely to maintain CCRF than oncology patients in whom these dysfunctional schedules are present to a lesser extent. From the literature, we chose to examine the dysfunctional schema Relentlessly strict standards/extremely high demands. Exploratively, we also examine the dysfunctional schemas Abandonment/Instability and Self-Sacrifice.
If the above schemas are indeed associated with higher levels of CCRF, we then ask what role acceptance of fatigue plays on the aforementioned correlation. We hypothesize that acceptance plays a mediating role in the correlation between dysfunctional schemas and fatigue: Dysfunctional schemas hinder acceptance of fatigue. Next, we hypothesize that the lower the degree of acceptance, the higher the perceived fatigue will be.
In addition to mediation, a moderating role of dysfunctional schemas could also be hypothesized. Therefore, the second hypothesis hypothesizes that there is a negative relationship between acceptance and fatigue, but only when the relevant dysfunctional schemas are present at low levels. When these dysfunctional schemas are present to a high degree, the relationship between acceptance and fatigue changes. Most likely, the dysfunctional schemas reduce the beneficial influence of acceptance.

| Fatigue | The Individual Stress Strength Checklist measures subjective fatigue and behavioral aspects related to it. It consists of 20 statements that examine how the respondent has felt over the past two weeks, indicating to what extent the statement applies to him/her. It measures a picture of fatigue that includes fluctuations over time. Four subscales are distinguished. The scoring method is on a 7-point Likert scale. A cut-off point for the total score is 76, indicating problematic fatigue. For the subjective fatigue subcategory, Normal = a score below 27. A score of 27 or higher is an indication of abnormal fatigue. A score of 35 or higher is considered an indication of severe fatigue. | Baseline |
| Dysfunctional schema | The Young Schema Questionnaire-S3 (YSQ-S3) provides insight into dysfunctional schemas that may be underlying patients' psychological problems. The YSQ-S3 consists of 90 items (statements) measuring 18 schemas including the dysfunctional schemas of ruthless standards/excessive demands, self-sacrifice and abandonment. The method of scoring is on a 6-point Likert scale. After taking the YSQ-S3, the average of all scores per scale is calculated for high predictive value. For most schema scales, a mean score of 2.5 or higher usually appears to fall in the clinical range. The cut-off value for Self-sacrifice and Compassionate norms/extreme demands is around a mean of 3. Internal consistency is adequate for all 18 scales: Cronbach's α=0.70 | Baseline |
| Acceptance | The Freiburg mindfulness Inventory-Short Form (FMI-SF) is a questionnaire consisting of two subscales: Presence (attention to experiences of the present moment) and Acceptance (an accepting attitude toward experiences). The FMI-SF has the advantage of being a short list of 14 questions that can be applied in a clinical setting. The items can be scored from 1 (rarely) to 4 (almost always). Both the FMI-14 as a whole (Cronbach's α = .85) and the factors Presence (Cronbach's α= .74) have adequate internal consistency, providing support for the reliability of the scale and subscales. | Baseline |
