This study aims to test and adapt the Turkish psychometric properties of the preventive health management self-efficacy related to premature labor (PHMSE-PL) scale for women of reproductive age.
The study follows a methodological approach. The original scale comprises 34 items distributed across 5 subscales and is structured on a five-point Likert scale. The study sample consisted of 351 women aged 19 to 49, all without any physical or mental disabilities, irrespective of marital status or pregnancy status. Exclusion criteria encompassed women engaged in healthcare professions such as medical faculty, nursing, or midwifery, as well as those with a history of preterm birth during pregnancy.
During the validity assessment of the scale, language, content, and construct validity were scrutinized. In the reliability phase, internal consistency and stability over time -analyses were conducted. Following confirmation of language validity, all items achieved a content validity index value exceeding 0.80. Exploratory and confirmatory factor analyses were employed to assess structural validity, revealing that the scale retained its original grouping into five sub-factors. These factors collectively accounted for 81.5% of the variance. The Cronbach's alpha coefficient for the entire scale reached 0.98, indicating high internal consistency. Test-retest analyses yielded a correlation coefficient of 0.99 between overall scale scores, demonstrating excellent consistency between the two measurement measurements.
The PHMSE-PL scale adapted to Turkish culture demonstrated high levels of validity and reliability.
本研究旨在测试和改编与早产相关的预防性健康管理自我效能感（PHMSE-PL）量表的土耳其心理测量学特性，适用于育龄妇女。
本研究采用方法学方法。原始量表由 34 个项目组成，分为 5 个分量表，采用五点 Likert 量表结构。研究样本由 351 名年龄在 19 至 49 岁之间的妇女组成，所有妇女均无身体或精神残疾，无论婚姻状况或怀孕状况如何。排除标准包括从事医疗专业（如医学系、护理或助产）的妇女以及在怀孕期间有早产史的妇女。
在对量表进行有效性评估时，考察了语言、内容和构念效度。在可靠性阶段，进行了内部一致性和随时间推移的稳定性分析。在确认语言有效性后，所有项目的内容效度指数值均超过 0.80。采用探索性和验证性因子分析评估结构效度，结果表明该量表保留了其原始的五个分组因素。这些因素共解释了 81.5%的方差。整个量表的 Cronbach's alpha 系数为 0.98，表明内部一致性较高。总体量表得分的测试-重测分析得出的相关系数为 0.99，表明两次测量之间具有极好的一致性。
改编为土耳其文化的 PHMSE-PL 量表具有较高的有效性和可靠性。
