This study evaluates the feasibility, reliability, and validity of the Parent's Perceptions of Primary Care measure (P3C) in an underserved population: children of Latino farm workers. Bilingual research assistants verbally administered the P3C, as well as a measure of child health-related quality of life (HRQL: the PedsQL 4.0) and demographic questions to 297 Latino farm worker parents of young children, in San Diego and Imperial Counties. The P3C was found to be feasible, as measured by a very low percent of missing/do not know values. Internal consistency reliability for the Total Scale and most subscales was strong. The P3C's validity was demonstrated through factor analysis of the subscales, by showing that scores were lower for children without a regular physician and for children experiencing foregone health care, and by demonstrating that P3C scores were related to HRQL. The P3C can be useful to various stakeholders in measuring primary care for vulnerable populations.
本研究评估了初级保健父母认知量表（P3C）在服务不足人群（拉丁裔农场工人子女）中的可行性、可靠性和有效性。双语研究助理对圣地亚哥县和帝国县的297名拉丁裔农场工人幼儿的父母进行了P3C量表、儿童健康相关生活质量量表（HRQL：儿童生活质量量表4.0版）以及人口统计学问题的口头调查。通过极低的缺失/不知道值百分比衡量，发现P3C是可行的。总量表和大多数子量表的内部一致性可靠性很强。通过对子量表的因子分析，表明没有固定医生的儿童和放弃医疗保健的儿童得分较低，并证明P3C得分与HRQL相关，从而证明了P3C的有效性。P3C在衡量弱势群体的初级保健方面对各类利益相关者可能有用。
