“…The findings of this systematic review have provided evidence for factors affecting psychosocial adjustment to colorectal cancer. Previous research has highlighted that those participants with an internal locus of control can adjust better to living with colorectal cancer as a chronic illness (Mititelu, 2016;Wilson, 2017). However, our results indicate that both internal locus of control and external locus of control can help with adjustment.…”

“…Both were found to have a major effect on the outcomes of coping with adversity . Some previous studies reported associations between subjective stress or optimism and emotional distress, fatigue, and cognitive difficulties; other studies reported that optimism predicted the course of symptoms over time . However, the present study is unique in its assessment of the extent to which change in psycho‐social parameters affects postchemotherapy symptoms.…”

“…Several studies found an association between a high level of optimism and reduced levels of fatigue, while in another study with various types cancer patients undergoing chemotherapy, no such association was reported. Several studies found either an association between optimism and cognitive difficulties in individuals with various types of cancer or no association . While most studies refer to optimism as a dispositional and relatively stable trait, it has also been shown that levels of optimism may change over time in response to life events, such as cancer …”

Objectives: Inconsistent findings were reported about the course of postchemotherapy symptoms; specifically, the effect of changes in optimism and perception of subjective stress on the evolution of symptoms remains understudied. This prospective study aimed (a) to examine the course of postchemotherapy symptoms of emotional distress, fatigue, and cognitive difficulties among breast cancer survivors and (2) to assess the effect of changes in optimism and subjective stress on the trajectory of these symptoms. Methods: Ninety-eight breast cancer survivors, diagnosed at stages I to III, aged 30 to 74, recruited consecutively (response rate 84.7%) completed fatigue, emotional distress, self-reported cognitive difficulties, optimism, and subjective stress questionnaires at three points in time: upon enrollment (1-6 months after completing treatment, Time 1) posttreatment, 6 months (Time 2), and 12 months (Time 3). A linear mixed-effects model was used to analyze the data. Results: Emotional distress decreased between time-points, level of cognitive difficulties remained stable, and a marginal decrease in fatigue was evident. Optimism or subjective stress predicted changes in each of the symptoms (P<.01), except for the effect of optimism on cognitive difficulties (P=.06). The interactions between time and optimism and between time and subjective stress were only significant regarding their effect on emotional distress (P<.05), showing that the strongest effect of these variables was at Time 2. Conclusion:The course of postchemotherapy symptoms shows patterns of stability and change over a 1-year period. Optimism and subjective perceptions of stress were shown to affect the decrease of symptoms. Therefore, these two factors should be specifically targeted in psycho-social interventions.

“…Oncological patients who consider that they have little control over their disease can feel more comfortable and safe delegating control to their oncologist (Helmes et al, 2002). Current studies found that the external LOC seemed to be associated with a lower prevalence of depression in cancer patients (Aarts et al, 2015; Wilson et al, 2018).…”

Objective: To investigate the mediator role of locus of control on the relationship between the Big Five personality traits and the manifestation of depression symptoms in cancer outpatients. Method: Participants consisted of 220 cancer outpatients (138 women and 82 men), evaluated individually at the hospital waiting room. The measures applied were as follows: The NEO-Five Factor Inventory (NEO-FFI), Multidimensional Health Locus of Control (MHLC) Scale and Hospital Anxiety and Depression Scale (HADS).Results: The factor structure of NEO-FFI was reexamined. A moderated mediation model was found for the powerful others external locus of control (LOC), depression symptoms and extraversion and conscientiousness traits across sex.Conclusions: Extraverted individuals can seek for others' support and use their attachments to find someone to guide them; conscientious patients can rely on their physician and follow every rule and orientation demanded, temporarily delegating to others the responsibility for their lives. All these strategies can help to decrease symptoms of depression. The perception of control can be taught, and it may be specifically relevant for mental health and in the performance of health behaviours.
