观察编码系统是唯一适合于调查夫妇和家庭的干扰过程，但其有效性在不同的人群是未知的。我们通过对低收入社区夫妇的互动数据进行因子分析，并使用广泛使用的爱荷华州家庭互动评定量表（IFIRS）进行编码，从而解决了这一问题。我们的样本414低收入，不同种族的新婚夫妇提供了24分钟的解决问题和社会支持行为的样本。评价者间的可靠性很强，由此产生的因素，反映积极的，消极的，有效的沟通，是非常相似的那些获得与白色中产阶级的样本。此外，夫妻更消极，积极性较低，在解决问题的对话比社会支持的对话，更有效，进一步支持IFIRS在这一人群的有效性。最后，我们讨论的优势和不足的国际财务报告准则时，用于低收入，种族多样化的人口。
Observational coding systems are uniquely suited for investigating interactional processes in couples and families, but their validity in diverse populations is unknown. We addressed this issue by applying factor analysis to interactional data collected from couples in low-income neighborhoods and coded with the widely used Iowa Family Interaction Rating Scales (IFIRS). Our sample of 414 low-income, ethnically diverse newlywed couples each provided 24-min samples of problem-solving and social support behavior. Interrater reliabilities were strong, and the resultant factors-reflecting positive, negative, and effective communication-were very similar to those obtained with White middle-class samples. Additionally, couples were more negative, less positive, and less effective in problem-solving conversations than in socially supportive conversations, further supporting the validity of the IFIRS in this population. We conclude by discussing the strengths and shortcomings of the IFIRS when used in a low-income, ethnically diverse population.
