Objective: To create, develop, and validate a scale that identifies the environmental and personal barriers that make it difficult to adhere to the practice of physical exercise on a regular basis in a population of Brazilian adults. Methods: We include adult individuals, aged 18–59 years, practitioners or former practitioners of physical exercise, with Brazilian Portuguese as their mother tongue. In the development and validation phases of the process, 6 specialists in the field of the health assessed the content validity: firstly, the specialists were asked to freely list the questions they would ask to investigate the barriers to adherence to regulating physical activity. Secondly, after compiling all the suggestions listed and eliminating suggestions with similar content, the items suggested in the first round were sent to the specialists so that an evaluation of all questions using a 5-point Likert scale and the content validity coefficient was calculated. We then evaluated the structural validity, construct validity, reliability, internal consistency, and ceiling and floor effects of the Regular Physical Exercise Adherence Scale (REPEAS). Results: Sixteen items were proposed to measure the factors that make it difficult to adhere to the regular practice of physical exercise. The internal structure of the REPEAS initially tested was based on the theoretical proposal of creating the instrument with two domains. After the structural analysis, we used the modification indices to identify the redundant items of the instrument. Consequently, the final version of the REPEAS after factor analysis had 12 items. Thus, the structure with 2 domains and 12 items presented adequate fit indices. With regard to construct validity, the REPEAS scores were compared in two distinct groups: irregular practitioners/ex-practitioners versus regular practitioners of physical exercise, in which a significant difference could be observed between groups (p < 0.001) for both the domains. Acceptable reliability was observed for the environment and personal domains, with ICC values of 0.86 and 0.94, in the same order. For internal consistency, Cronbach's alpha value was 0.908 (environmental domain) and 0.915 (personal domain), these values being adequate for the REPEAS. Conclusion: The REPEAS is a scale with a valid two-dimensional internal structure, consisting of 12 items, reliable and with a valid construct, which supports its use in the clinical, epidemiological, and research contexts in Brazil.

Objectives: To evaluate the psychometric properties of the Quick Inventory of Depressive Symptomatology (QID-SR16), a self-report instrument based on the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria that assesses the severity of depression symptoms, in the Brazilian population. Methods: Participants were 4,400 Brazilians over the age of 15 years recruited for an online survey assessing depressive symptoms during the early phase of the coronavirus disease 2019 (COVID-19) pandemic in Brazil. The internal consistency, construct validity, and convergent and discriminant validity of the QIDS-SR16 were evaluated. Results: The model tested was considered an adequate fit to the data (comparative fit index [CFI] = 0.947, Tucker-Lewis index [TLI] = 0.927, and root-mean-square error of approximation [RMSEA] = 0.051) and its internal consistency was good, with a Cronbach's alpha of 0.71 and an average item correlation of 0.23. The correlations between the total QIDS-SR16 score and the total scores of the Patient Health Questionnaire (PHQ-9) instruments (r = 0.67, p < 0.001), the Posttraumatic Symptoms Checklist (PCL-5) (r = 0.61, p < 0.001), and the Patient-Reported Outcomes Measurement Information System (PROMIS) (r = 0.60, p < 0.001) indicate good concurrent and convergent validity. Conclusion: The QIDS-SR16 has robust psychometric properties in terms of its internal consistency, construct validity, and convergent and discriminant validity. The Portuguese version of the QIDS-SR16 is an adequate instrument for assessment of depressive symptoms in the context of an online survey. [ABSTRACT FROM AUTHOR]

Studies highlight that although the spiritual/religious dimension is commonly used as a resource for coping with stress and suffering, sometimes this dimension can also be a locus of struggles. The Religious and Spiritual Struggles (RSS) Scale, composed of 26 items (extended version), is an instrument that assesses the presence of six types of spiritual struggles, categorized into three major categories: Intrapersonal, Interpersonal, and Supernatural. More recently, studies have presented a leaner version, with 14 items (short version), also suitable for evaluating religious/spiritual struggles. This study aimed to validate the RSS Scale, in its two versions, in the Brazilian cultural context and was able to attest to its quality and reliability, albeit with small variations. The Brazilian extended version presented six components (similar to the original version) explaining 68.48% of variance and 0.907 of KMO. Two items were withdrawn due to low loadings, but the psychometric qualities of both versions in two different samples (one wide sample and one with LGBTQIA+ individuals) were maintained. The reliability (Cronbach's alpha) for each one of the six components ranged from 0.78 to 0.88 (24 items) and from 0.73 to 0.83 (14 items). The TLI and CFI were, respectively, 0.934 and 0.945 (24 items) and 0.982 and 0.988 for the short version (14 items). Furthermore, convergent validity tests indicated correlations with the Satisfaction with Life Scale. The RSS Scale (the Brazilian versions with 24 and 14 items), demonstrated reliability in the studied sample and can be applied in clinical and research contexts. [ABSTRACT FROM AUTHOR]

Patients with liver metastasis of colorectal cancer (CRC) experience important lifestyle changes that impair the quality of life (QoL). The use of instruments is important to assess the cancer patients' QoL. To develop a Brazilian translation of the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Colorectal Liver Metastases (QLQ-LMC21) questionnaire, and to investigate psychometric validity in patients with CRC with liver metastases, patients with liver metastasis from CRC answered the Brazilian versions of EORTC core Quality of Life Questionnaire-Core 30 (QLQ-C30) and the QLQ-LMC21 module, a demographic data questionnaire and a questionnaire to assess understanding against the translated QLQ-LMC21. Data collection was performed in three Southern hospitals in Brazil, from August 2017 to August 2019. Descriptive analyses and Spearman’s correlation tests were performed for construct and criterion validity. The Cronbach's alpha test was performed to assess reliability. Significant values were p < 0.05. Ten patients participated in the study for the pilot test and 106 for validation, with a mean age of 58.2 + 12.4 years old. The translated questionnaire was easy to understand for the participants in the pilot test phase, with no need for modification. In the validation of the convergent construct, all the correlations were significant (p < 0.001) and with coefficients above 0.53. In the discriminant validity, among items of different scales, the values of the divergent correlations were pain scale (0.005 to 0.186) and fatigue (-0.01 to 0.186), all non-significant. In the criterion validation, the correlations were significant, p < 0.05, and higher among similar scales of the QLQ-LMC21 and QLQ-C30, p-value < 0.001. The total internal consistency of the questionnaire was adequate, with a Cronbach's alpha value of 0.790. The Brazilian version of the QLQ LMC21 proved to be a valid reliable questionnaire to be used in conjunction with the QLQ-C30. [ABSTRACT FROM AUTHOR]
