There are several instruments available to assess pain-related expectations, and most studies haven't reported the measurement properties of such scales.<h4>Objectives</h4>This study aimed to adapt and examine the measurement properties of the Stanford Expectations of Treatment Scale (SETS), the Treatment Expectations in Chronic Pain Scale (TEC), and four single-item expectations scales in Brazilian Portuguese in CLBP.<h4>Methods</h4>A total of 203 patients participated in the study. The cross-cultural adaptation followed guideline recommendations. Confirmatory factor analysis (CFA) and Cronbach's α were used to assess structural validity and internal consistency, respectively. Intraclass Correlation Coefficient (ICC) was used to test for reliability, and Smallest Detectable Change to analyze measurement error. Spearman's correlation was used to assess hypothesis testing for construct validity.<h4>Results</h4>CFA confirmed a two-factor model for the SETS-Br, and TEC-Br scales showed adequate CFA fit indexes. Internal consistency was acceptable (α ≥ .70) for SETS-Br positive domain, TEC-Br Ideal, and TEC-Br Predicted, but not for SETS-Br negative domain. Reliability was acceptable for the six expectation scales included in the study (ICC>.74). All the expectation scales confirmed at least 75 % of the hypotheses raised a priori for construct validity.<h4>Conclusions</h4>TEC-Br scales met the criteria for good quality for all the measurement properties assessed. Our results suggest that the six scales tested seem to measure different dimensions of the expectations construct, since they showed weak to moderate correlations when compared.","is_dataset_classified":null,"base_score":0.6931471805599453,"endowment":0.6931471805599453,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"41468808","pmcid":null,"openalex_id":"https://openalex.org/W4417300012","authors":[],"funders":[{"funder_name":"CAPES","grant_id":"","title":null}],"total_grants":1,"fwci":0.8833,"citation_percentile":0.79575627,"influential_citations":0,"citation_trend":[{"year":2026,"count":1}],"oa_status":"closed","license":"https://doi.org/10.15223/policy-004","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S246878122500219X?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S246878122500219X?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.msksp.2025.103471","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/41468808","host_type":"repository"}],"fields_of_study":["Musculoskeletal pain and rehabilitation","Health Systems, Economic Evaluations, Quality of Life","Occupational Health and Performance"],"mesh_terms":["Adult","Aged","Brazil","Cross-Cultural Comparison","Factor Analysis, Statistical","Female","Humans","Male","Middle Aged","Pain Measurement","Psychometrics","Surveys and Questionnaires","Reproducibility of Results","Low Back Pain","Chronic Pain"],"keywords":["Low back pain","Measure (data warehouse)","Quality (philosophy)","Scale (ratio)","Level of measurement","Back pain","Chronic Low Back Pain","Expectation","questionnaires","Measurement Properties","Cross-cultural Adaptation"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-31T10:14:07.062922Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
