The preventive health management self-efficacy related to preterm labor scale in reproductive-aged women: Validation of Turkish reliability and factor structure.

Aim: 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.

Methods: 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.

Results: 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.

Conclusions: The PHMSE-PL scale adapted to Turkish culture demonstrated high levels of validity and reliability.
