Background: Cancer-related cognitive impairment is a common and potentially debilitating symptom experienced by patients with non-central nervous system (CNS) cancers, with negative impact on their quality of life. The Functional Assessment of Cancer Therapy-Cognitive Function-Version 3 (FACT-Cog-v3) is the most extensively used instrument specifically developed to evaluate cognitive complaints in adult cancer patients. Nevertheless, this self-report measure is not yet validated for the Portuguese population. Therefore, the purpose of this study was to evaluate the psychometric properties of the FACT-Cog-v3 among patients with non-CNS cancers in Portugal. Methods: The validation study was conducted based on a convenience sample of 281 patients with non-CNS cancers, aged between 18 and 65 years, recruited online. A confirmatory factor analysis (CFA) was used to test the factor structure of the Portuguese FACT-Cog-v3 version; internal consistency analysis was also conducted. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30–version 3) and the Hospital Anxiety and Depression Scale (HADS) were also used to test the concurrent, convergent, and discriminant validity of the scale. Results: CFA supported a four-factor model with good fix indexes and internal consistencies: perceived cognitive impairments (α = 0.97), comments from others (α = 0.92), perceived cognitive abilities (α = 0.93), and impact on quality of life (α = 0.92). Concurrent, convergent, and discriminant validities were confirmed. Moderate and strong correlations were found between the FACT-Cog-v3 subscales and the QLQ-C30 cognitive functioning subscale. Good convergent validity, with moderate correlations, was found between the FACT-Cog-v3 subscales and the HADS-A, HADS-D, and QLQ-C30 fatigue, sleep disturbance, and global health status subscales. Acceptable discriminant validity, with weak and moderate correlations, was demonstrated between the FACT-Cog-v3 subscales and the QLQ-C30 pain and nausea/vomiting subscales. Conclusions: The Portuguese FACT-Cog-v3 version can be considered a reliable and valid measure to assess cognitive concerns of patients with non-CNS cancers, with relevance for research and clinical practice.

The Modified Caregiver Strain Index is a widely used tool to screen for caregiver strain in family caregivers. This study presents the Portuguese version of the Modified Caregiver Strain Index and explores its psychometric properties in a sample of 347 informal caregivers of older dependent individuals. Factor analysis revealed a two-factor structure and indicated satisfactory internal consistency. Criterion-related validity was supported by positive significant correlations with the emotional health of the caregiver (psychological distress). The findings show evidence of reliability and validity of the Portuguese version of the Modified Caregiver Strain Index encouraging its use in clinical and research fields.

Aim: Cognitive concerns are one of the most frequently reported symptoms by breast cancer survivors. This study aimed to evaluate perceived cognitive functioning in Portuguese women with breast cancer treated with chemotherapy.Methods: A cross‐sectional study enrolling 146 women (73 with breast cancer and 73 healthy) was conducted from August to October 2017, invited to participate through online dissemination. Participants completed self‐reported questionnaires to collect sociodemographic and clinical data and assess perceived cognitive functioning and psychological adjustment variables (anxiety and depression).Results: Compared to healthy women, women with breast cancer showed significantly lower scores on the Functional Assessment of Cancer Therapy‐Cognitive Function (FACT‐Cog) subscales and higher levels of depression. Both groups showed significant negative correlations between perceived cognitive functioning and anxiety and depression. Health status and depression seem to better explain perceived cognitive functioning, with health status adding significantly more explained variance beyond sociodemographic and psychological adjustment variables.Conclusion: The current findings provide evidence for the existence of more cognitive complaints among Portuguese women with breast cancer, compared to healthy individuals. Anxiety, depression, age and education also explain perceived cognitive functioning. Considering that health status and psychological adjustment seem to significantly explain perceived cognitive functioning, special attention should be given by health‐care professionals, including nurses, to designing clinical interventions for breast cancer patients to help manage cognitive impairment.

Cognitive difficulties are highly prevalent and negatively impact cancer survivors’ quality of life. The UCLA Cognitive Rehabilitation Intervention Program (in short, UCLA program) is an evidence-based intervention developed and tested in the US to address the cognitive complaints of cancer survivors. Since there are no cognitive rehabilitation programs available for Portuguese cancer-related settings, this study aimed to culturally adapt the UCLA program to Portugal. Nine steps were implemented for this cultural adaptation: needs assessment, initial contacts, translation, cultural adaptation, independent review by a panel of experts (n = 6), focus group discussions with cancer survivors (n = 11), systematization of inputs and improvement of the final materials, fidelity check, and preliminary acceptability assessment. The findings suggested that changes to the original materials were needed. A Portuguese name, “CanCOG^®—Reabilitação Cognitiva no Cancro” (in English “CanCOG^®—Cognitive Rehabilitation in Cancer”), and a logo were created to make it more memorable and appealing for the Portuguese population. The language was adjusted to ensure content accessibility and semantic and conceptual equivalence. Finally, references to several cultural aspects, such as habits, customs, and traditions, were adapted to fit the new cultural context. The UCLA program may be a promising tool to help alleviate the cognitive difficulties reported by cancer survivors in different cultural contexts. Future research is needed to confirm the feasibility, acceptability, and preliminary efficacy of its Portuguese version, “CanCOG^®—Reabilitação Cognitiva no Cancro”.

Objective: Cancer‐related cognitive impairment (CRCI) negatively impacts the quality of life of non‐central nervous system (non‐CNS) cancer survivors. Detecting these cognitive changes remains challenging due to the lack of standardized CRCI classification and detection criteria. This study aimed to establish cut‐off scores for the perceived cognitive impairment (CogPCI) subscale of the European Portuguese version of the Functional Assessment of Cancer Therapy‐Cognitive Function—Version 3 (FACT‐Cog‐v3). Methods: We analyzed data from 266 Portuguese‐speaking non‐CNS cancer survivors and performed a receiver operating characteristic (ROC) curve analysis to evaluate the diagnostic validity of the CogPCI subscale of the FACT‐Cog‐v3 to detect meaningful perceived CRCI. Results: The CogPCI subscale demonstrated good screening performance in identifying individuals with and without clinically relevant CRCI, as indicated by a moderate‐to‐high area under the curve (AUC) score of 0.87. A suggested optimal cut‐off score of < 51 provided good sensitivity (81.2%) and specificity (78.9%) for CogPCI to differentiate between the two groups. Over half of the participants reported significant cognitive complaints, highlighting the urgent need for standardized cognitive assessments in oncology. Conclusions: This study contributes valuable insights into the early and fast detection and intervention of CRCI in Portugal. Using a brief, validated, self‐report cognitive assessment tool can enhance the management of cognitive symptoms in non‐CNS cancer survivors.
