Background and PurposeTo assess the psychometric properties of the PAM13 Brazilian-Portuguese (PAM13-B) among outpatients with chronic diseases.Methods513 adults participated, diagnosed with a chronic disease for more than 6 months, under outpatient monitoring. Reliability was tested using internal consistency and test-retest reliability. Construct validity was verified through different techniques (correlation between activation and self-esteem measures, anxiety, depression and health status), known-groups validity and dimensionality by means of confirmatory factor analysis. Significance was set at 0.05.ResultsThe PAM13-B presented appropriate results for internal consistency (α = 0.83) and test–retest reliability (intraclass correlation coefficient [ICC] = 0.81). A moderate correlation was found between activation and self-esteem only (r = 0.43, p < 0.001). The one-dimensional structure was not confirmed in the sample analyzed.ConclusionsIn the study sample, the version PAM13-B demonstrated its reliability and validity, but with a two-factor structure.

Objective: To compare the distributions of measurements of the Dutch Fatigue Scale (DUFS), Dutch Exertion Fatigue Scale (DEFS), and Fatigue Pictogram tools, according to the New York Heart Association (NYHA) Functional Classification and left ventricular ejection fraction (LVEF). Method: Methodological, cross-sectional study with 118 patients with heart failure. Variance analysis, Pearson's correlation, and Fisher's exact tests were carried out, with a significance level of 0.05. Results: There was an increase in the DUFS and DEFS means with worsening of the NYHA-FC (p<0.001, for both tools). Correlations among the LVEF resulted in positive and weak magnitude for the DEFS (r=0.18; p=0.05) and for the DUFS (r=0.16; p=0.08). Just the item A on the Fatigue Pictogram had an association with the NYHA-FC (p<0.001) and the LVEF (p=0.03). Conclusion: Three tools detected worsening in fatigue levels according to the illness severity assessed by the NYHA-FC.

Results have shown that the adapted version is reliable and valid, although the theoretical model cannot be explained in a single dimension.

Objective:To identify and describe the instruments used to assess patients' expectations toward spine surgery. Method: An integrative review was carried out in the databases PubMed, CINAHL, LILACS and PsycINFO. Results: A total of 4,402 publications were identified, of which 25 met the selection criteria. Of the studies selected, only three used tools that had confirmed validity and reliability to be applied; in five studies, clinical scores were used, and were modified for the assessment of patients' expectations, and in 17 studies the researchers developed scales without an adequate description of the method used for their development and validation. Conclusion: The assessment of patients' expectations has been methodologically conducted in different ways. Until the completion of this integrative review, only two valid and reliable instruments had been used in three of the selected studies.
