OBJETIVES.: Our aim was to evaluate the psychometric properties of the FACES-III among Peruvian high school students.
MATERIALS AND METHODS.: This is a psychometric cross-sectional study. A probabilistic sampling was applied, defined by three stages: stratum one (school), stratum two (grade) and cluster (section). The participants were 910 adolescent students of both sexes, between 11 and 18 years of age. The instrument was also the object of study: the Olson's FACES-III. The analysis included a review of the structure / construct validity of the measure by factor analysis and assessment of internal consistency (reliability).
RESULTS.: The real-cohesion scale had moderately high reliability (Ω=.85) while the real-flexibility scale had moderate reliability (Ω=.74). The reliability found for the ideal-cohesion was moderately high (Ω=.89) like for the scale of ideal-flexibility (Ω=.86). Construct validity was confirmed by the goodness of fit of a two factor model (cohesion and flexibility) with 10 items each [Adjusted goodness of fit index (AGFI) = 0.96; Expected Cross Validation Index (ECVI) = 0.87; Normed fit index (NFI) = 0.93; Goodness of fit index (GFI) = 0.97; Root mean square error of approximation (RMSEA) = 0.06].
CONCLUSIONS.: FACES-III has sufficient reliability and validity to be used in Peruvian adolescents for the purpose of group or individual assessment.
我们的目标是评估秘鲁高中生中FACES-III的心理测量特性。
这是一项心理测量横断面研究。采用概率抽样，分三个阶段定义：第一阶段（学校）、第二阶段（年级）和聚类（班级）。参与者为910名11至18岁的青少年学生，男女皆有。研究工具也是研究对象：奥尔森的FACES-III。分析包括通过因子分析对测量的结构/构想效度进行审查以及对内部一致性（信度）进行评估。
实际凝聚力量表具有中等偏高的信度（Ω = 0.85），而实际灵活性量表具有中等信度（Ω = 0.74）。理想凝聚力的信度中等偏高（Ω = 0.89），理想灵活性量表也是如此（Ω = 0.86）。通过一个双因素模型（凝聚力和灵活性）的拟合优度得到证实，每个因素有10个项目[调整后的拟合优度指数（AGFI）= 0.96；预期交叉验证指数（ECVI）= 0.87；规范拟合指数（NFI）= 0.93；拟合优度指数（GFI）= 0.97；近似误差均方根（RMSEA）= 0.06]。
FACES-III具有足够的信度和效度，可用于秘鲁青少年进行团体或个体评估。
