The Effect of Attentional Bias on Emotions in Patients with Breast Cancer

BACKGROUND

Attentional bias may influence the emotional experiences of breast cancer patients, both positively and negatively. This study aimed to investigate attentional bias in breast cancer patients and its impact on their emotions.

METHOD

Thirty-eight breast cancer patients completed a modified dot-probe task and the Depression Anxiety and Stress Scale to assess attentional bias and emotional states. Attentional bias was measured by analyzing response times to different stimuli in the modified dot-probe task. Emotional stimuli included 80 pairs of facial images depicting sad-neutral, fearful-neutral, happy-neutral, and neutral-neutral expressions. Attentional bias components were observed at stimulus presentation durations of 300 ms and 1500 ms. Differences in emotional responses among breast cancer patients with varying attentional biases were compared.

RESULTS

Breast cancer patients exhibited attentional avoidance of sad and happy stimuli at 300 ms. Further analysis revealed that patients who exhibited attentional avoidance of sad stimuli at 300 ms reported higher levels of anxiety and stress. Those with attentional avoidance of fearful stimuli at 1500 ms reported increased anxiety, while individuals showing attentional avoidance of happy stimuli or difficulty disengaging from happy stimuli at 1500 ms reported higher levels of depression and stress.

CONCLUSION

Breast cancer patients demonstrated an attentional bias toward emotional stimuli, particularly avoidance of sad and happy stimuli in 300 ms. Different components of attentional bias were associated with distinct negative emotional outcomes.

Attentional Bias Toward Reproduction-Related Stimuli and Fertility Concerns Among Breast Cancer Survivors

The current study examined whether an attentional bias exists for reproduction-related visual cues among breast cancer survivors and its relationship with fertility concerns and emotional distress. Breast cancer survivors (n = 38) aged 18-40 were compared to 37 healthy women recruited from the general population. Attentional bias was investigated using a visual dot-probe task and response times (RT) were measured. Participants also completed several questionnaires, including the Reproductive Concerns After Cancer Scale (RCACS) and the Hospital Anxiety and Depression Scale (HADS). Biased cognitive processing toward reproduction-related stimuli was observed for all young women. However, attentional bias was a significant predictor of concerns about partner disclosure of fertility status, with higher bias scores associated with higher levels of concern only for breast cancer survivors. The desire to have a (or another) biological child was also a significant predictor of higher concerns related with fertility potential for all young women. Higher vigilance regarding reproduction-related cues seems to lead to higher concerns among women with breast cancer history whose fertility is threatened. This result may have important research and clinical implications. Interventions focused on goal-oriented attention self-regulation and problem-solving can help to manage fertility concerns and distress in the course of the disease.

Interpretation Bias in Breast Cancer Survivors Experiencing Fear of Cancer Recurrence

Introduction: Fear of cancer recurrence (FCR) is a prevalent and persistent challenge that many cancer survivors endure. While the role of interpretation bias, a tendency to perceive ambiguous situations as threatening, has been established in the onset and maintenance of FCR, few studies have examined cancer-related interpretation bias specifically. Grounded in the cognitive formulation of FCR, the current study aimed to fill this gap by investigating the relationship between cancer-related interpretation bias, FCR, and somatic symptoms, and examining whether bias mediates the relationship between somatic symptoms and FCR.

Materials and Methods: This study used baseline data from a randomized controlled trial of a cognitive bias modification intervention. Breast cancer survivors (n = 110) provided demographic and medical background information as well as self-report measures of FCR and severity of somatic symptoms. A computer-based assessment of interpretation bias was used to measure cancer-related interpretation bias on several bias indices: percentage of cancer-related threat endorsement, and percentage of benign endorsement; mean reaction time (RT) for threat, and mean RT for benign endorsement.

Results: Higher threat endorsement was linked to higher Overall Fear and emerged as a mediator of the relationship between overall somatic symptoms and Overall Fear. We also found that older age was related to longer benign endorsement RT.

Conclusion: This study contributes understanding of factors related to cancer-related interpretation bias and provides evidence that bias may influence the relationship between somatic symptoms and FCR in cancer survivors.

An experimental study to identify key psychological mechanisms that promote and predict resilience in the aftermath of treatment for breast cancer

OBJECTIVE

Women living with and beyond breast cancer (BC) frequently encounter cancer-related information in day-to-day life. The extent they are emotionally resilient to this information differs between women. Identifying key modifiable psychological mechanisms predicting resilience in these women could highlight targets for interventions to improve resilience in others. This study investigates resilience over time in women living beyond BC and how this relates to individual differences in the way the brain processes information.

METHODS

Seventy women within a year of finishing first-line treatment for BC (clinical and community recruitment) completed computerised tasks to assess the tendency to attend to cancer information (dot-probe task), the tendency to draw negative cancer-related interpretations from ambiguous information (ambiguous scenarios task) and extent of executive functioning (attentional network task). Questionnaires were completed assessing resilience, and other clinically relevant psychological variables (fear of cancer recurrence, distress, quality of life, and worry) at the time of the laboratory tasks (T1) and again 6 months later (T2).

RESULTS

The only cognitive process associated with self-reported resilience was interpretation bias. Generating more negative cancer-related interpretations of ambiguous information at T1 significantly predicted resilience at T2, whilst controlling for T1 resilience and other clinically relevant variables. Furthermore, resilience scores were relatively stable over time and moderately correlated with other clinically relevant variables.

CONCLUSIONS

This study is the first to identify a key cognitive mechanism that predicts resilience in women living beyond BC. This finding suggests interventions to reduce cancer-related interpretations of ambiguous information could promote resilience in women living beyond BC.

The role of interpretation biases and symptom burden in fear of cancer recurrence/progression among ovarian cancer survivors

BACKGROUND

Models of fear of cancer recurrence or progression (FCR/P) suggest that the way in which people interpret ambiguous physical symptoms is an important contributor to the development and maintenance of FCR/P, but research has not investigated this claim. The aim of this study is to fill that gap.

METHODS

This was a cross-sectional study. Sixty-two women with ovarian cancer reported completed measures of FCR/P, an interpretation bias task and a symptom checklist. The healthy control group (n = 96) completed the interpretation bias task.

RESULTS

Women with ovarian cancer were more likely to interpret ambiguous words as health-related compared to healthy women (p < 0.001; Cohen's d = 1.28). In women with cancer, FCR/P was associated with overall symptom burden (r = 0.25; p = 0.04) and interpretation bias score (r = 0.41; p = 0.001), but interpretation bias and symptom burden were not related (r = 0.22; p = 0.09). Interpretation bias did not moderate the relationship between symptoms and FCR/P.

CONCLUSIONS

We found that women with ovarian cancer interpreted ambiguous words as health related more often compared to women without cancer, and this bias was greater for women with higher FCR/P. Symptom burden was also associated with FCR/P. However, interpretation bias did not moderate the relationship between physical symptoms and FCR/P. Hence, the central tenet of the Cancer Threat Interpretation model was not supported in women with ovarian cancer.

The Generalization of Conscious Attentional Avoidance in Response to Threat Among Breast Cancer Women With Persistent Distress

Objectives

A sample of women with persistent distress following breast cancer (BC) previously exhibited attentional bias (AB) away from supraliminally presented cancer-or threat-related information, responses consistent with avoidance coping, and showed negative interpretation bias. Here, we attempt to characterize the nature of supraliminal AB and interpretation bias in that sample of women by comparing against healthy controls.

Methods

Extending our previous work, we compared AB patterns for supraliminally presented negatively valenced words and cancer-related information (CRI) assessed by modified dot-probe tasks and negative interpretation bias assessed by an ambiguous cue task between 140 BC women previously identified as featuring low-stable or persistent high anxiety and 150 age-matched non-BC healthy controls having HADS-defined low or high anxiety (HADS-anxiety scores = 8).

Results

Attentional avoidance of non-cancer-related negatively valenced words was seen among the anxious BC group, while heightened attention toward such words was seen in anxious healthy controls, F(3, 282) = 3.97, p = 0.009. However, all anxious women in both BC and healthy groups directed attention away from CRI under supraliminal conditions. Interpretation bias scores were significantly higher in BC women with high anxiety vs. healthy controls with high anxiety, F(3, 282) = 13.26, p < 0.001.

Conclusion

Women with high anxiety generalized conscious attentional avoidance responses to negatively valenced stimuli, indicating a likely hypersensitivity to potential threat in ambiguous cues and exaggerated threat perception. This may cause (or reflect) maladaptive emotional regulation. Attention focus training, reducing threat salience or modifying threat appraisal, may help women alleviate anxiety levels after BC.

The role of metacognition and its indirect effect through cognitive attentional syndrome on fear of cancer recurrence trajectories: A longitudinal study

OBJECTIVE

This longitudinal study mapped distinct trajectories of fear of cancer recurrence (FCR) over 12 months among patients with breast (BC) or colorectal (CRC) cancer, and examined if metacognition, indirectly via attentional bias, intrusive thoughts and avoidance (hallmarks of cognitive attentional syndrome; CAS) predicted FCR trajectory membership.

METHODS

Two hundred and seventy BC (n = 163) or CRC (n = 107) patients were assessed at 8-weeks, 3-, 6-, and 12-months postsurgery on a measure of FCR (FCRI-SF). Metacognition (MCQ-30), Intrusive and Avoidant Thoughts (CIES-R) and attentional bias (dot-probe tasks) were assessed at baseline. Latent growth mixture modeling identified FCR trajectories. Fully-adjusted Multinomial Logistic Regression identified whether direct and indirect effects of metacognition through CAS determined FCR trajectory membership.

RESULTS

Three distinct FCR trajectories were identified, namely, low-stable (62.4%), high-stable (29.2%), and recovery (8.3%). Negative beliefs about worry, cognitive confidence, and age predicted FCR trajectories (χ² (6) = 38.31, P<.001). Compared with Low-stable group, Recovery FCR patients held greater Negative beliefs about worry (OR = 1.13, P = .035) and High-stable FCR patients reported poorer Cognitive confidence (OR = 1.12, P = .004). The effect of Negative beliefs about worry was partially mediated by avoidance (β = .06, 95% CIs 0.03-0.12) and fully mediated by intrusive thoughts (β = .14, 95% CIs 0.08-0.20). Attentional bias did not predict FCR trajectories.

CONCLUSIONS

While most patients experienced low level of FCR, 3 in 10 persistently worried about cancer returning over the first 12-months postsurgery. Modifying metacognitive knowledge to interrupt maladaptive cognitive processing including intrusion and avoidance may be an effective therapeutic intervention for patients at risk of persistent FCR.
