Need for Affect Questionnaire (NAQ-S): Construct Validity, Invariance and Reliability

Abstract Two studies (N=457) examined the psychometric properties of the short version of the Need for Affect Questionnaire (NAQ-S) in the Brazilian context. In the first study, a principal components analysis indicated a two-factor structure, with five items each: approach (α= .70) and avoidance (α= .75). This structure was confirmed in the second study (GFI= .92; CFI= .90), and it was invariant across gender. To verify the correlates of NAQ-S, we used measures to evaluate the human values, loneliness and need to belong in both studies, besides the five personality factors in the second study. The results showed that higher need for affect was associated with higher extraversion, higher scores in excitement and interactive values, and with lower loneliness scores. The studies support the validity of the NAQ-S in Brazil, showing its usefulness for research purposes.

摘要：本研究通过两项实验（样本量N=457），考察了巴西情境下情感需求问卷简版（Need for Affect Questionnaire, NAQ-S）的心理测量学特征。在第一项研究中，主成分分析结果显示该问卷具备双因子结构，每个维度包含5个条目：趋近维度（克朗巴赫α系数=0.70）与回避维度（克朗巴赫α系数=0.75）。该双因子结构在第二项研究中得到验证（拟合优度指数Goodness of Fit Index, GFI=0.92；比较拟合指数Comparative Fit Index, CFI=0.90），且在不同性别群体中均具备测量等值性。为验证NAQ-S的效标关联效度，两项实验均采用了评估人类价值观、孤独感与归属感需求的量表；第二项研究额外纳入了大五人格因素的测量。结果表明，更高的情感需求水平与更高的外倾性得分、兴奋型及互动型价值观得分呈正相关，与更低的孤独感得分呈负相关。本研究证实了NAQ-S在巴西人群中的效度，证明其可有效应用于相关学术研究。
