Abstract
ABSTRACT Objective: to test the psychometric validity of an instrument to assess family effectiveness strategies and its reliability for use with Brazilian families. Method: this is a methodological study, content validation, construct, criterion, which used exploratory and Confirmatory Factor Analysis and reliability. The sample consisted of 100 families. Data were collected from October 2017 to March 2018. Results: the percentage of agreement among family health experts was 100%, with a perfect Content Validity Index and reliability (1.00). For the target audience (pre-test), 89.3% of agreement and Content Validity Index of 0.89 were obtained. Construct validity had a total explained variance of 73.8%. The concurrent criterion validity presented a correlation coefficient (ρ) of 0.75 (p = 0.004). Reliability had a Cronbach’s α coefficient of 0.82 for the full scale and a range of 0.62 to 0.82 in the instrument’s goals. Conclusion: the instrument proved to be valid and reliable to assess the effectiveness of the functioning of Brazilian families.
Highlights
The family is a unit with structure and organization that interacts with the environment
International recommendations, from an entity composed of specialists in family health, pointed to the need for nurses to have instruments to assess family functionality or the level of family health based on the systemic approach[2,3]
It was evidenced that, in Brazil, one of the instruments available to assess family functionality with a systemic approach is the Family Environment Scale[5] and there is no record of use of The Strategies in Families-Effectiveness (ASF-E), which is based on a consistent theoretical model, developed by an English-speaking nurse, tested and validated in the United States[6]
Summary
The family is a unit with structure and organization that interacts with the environment It is a system composed of subsystems, shaped by the feeling of belonging and the commonality of responsibilities, which have distinct relationships with family members[1]. It was evidenced that, in Brazil, one of the instruments available to assess family functionality with a systemic approach is the Family Environment Scale[5] and there is no record of use of The Strategies in Families-Effectiveness (ASF-E), which is based on a consistent theoretical model, developed by an English-speaking nurse, tested and validated in the United States[6]. Other ASF-E tests and validations were developed with families in Mexico[7], in Colombia[8], in Germany and Switzerland[9] and in Finland[10]
