Development and Validation of the EFFAM Scale (Family Functioning Scale-Madrid).

Most models that analyse risk and protective factors during adolescence include the family system and family functionality as key elements. For this reason, Family Counselling Services play an important role in addressing adolescent problems. These services require quick and easy-to-apply assessment tools that integrate different dimensions of family functioning. To develop and validate a brief scale for use in Family Counselling Services, exploring and confirming its factorial structure and testing its psychometric properties. Confirmatory Factor Analysis using structural equation modeling. 441 family members in seven units. Results: A 5-factor structure was confirmed, with a good fit. All the Average Variance Extracted values were higher than the Maximum Shared Squared Variance values. The results confirm the structure of the Family Functioning Scale-Madrid. In addition, the scale demonstrates adequate psychometric properties and stable structure during two evaluation periods with different samples. The instrument is considered reliable and consistent for of assessing family intervention carried out in Family Counselling Services. Highlights: What is known so far? Family system and functionality has a relevant role as a risk and/or protective factor with respect to maladaptive behaviours. One common demand of Family Counselling Services is to be able to count on assessment protocols and instruments adapted to their target population. Available evidence provides few instruments that assess family functioning in an agile way. What does this article contribute? This study provides a brief, reliable instrument with optimal psychometric properties. Family Functioning Scale-Madrid assesses specific dimensions of family change in counseling. Theoretical structure of Family Functioning Scale-Madrid aligns with the Circumplex and Family Stress models. [ABSTRACT FROM AUTHOR]
