The Psychosocial Effects of Prenatal Education With the Indivisible Self Model

Psychological Well-Being Scale

Participants' current levels of psychological well-being will be assessed using the "Psychological Well-Being Scale" developed by Diener et al. (2009-2010). This scale is a measurement tool developed to complement existing well-being measures and aims to assess individuals' socio-psychological well-being levels. The scale has a 7-point Likert-type response format and consists of a total of 8 items, each rated from "1 = Strongly disagree" to "7 = Strongly agree". All items consist of positive statements, and the possible scores on the scale range from 8 to 56. Higher scores indicate a higher level of psychological well-being. The internal consistency of the scale was found to be α = .87 using Cronbach's alpha coefficient.

Revised Emotional Consistency Scale

Participants' levels of sense of coherence will be assessed using the Revised Emotional Coherence Scale, developed by Bachem and Maercker in 2016 to improve upon Antonovsky's original model. Based on Antonovsky's "Sense of Coherence" theory, this scale aims to assess individuals' perceptions of their life experiences as meaningful, comprehensible, and manageable. The scale uses a five-point Likert-type response format, with items rated from "1 = Not true at all" to "5 = Very true". The minimum possible score is 13, and the maximum is 65. Higher scores indicate that individuals perceive their lives as more meaningful, comprehensible, and manageable, thus indicating a higher level of emotional coherence. In the Turkish validity and reliability study of the scale, the Cronbach's alpha coefficient for overall internal consistency was determined as α = 0.82. The alpha values for the sub-dimensions are α = 0.77 for significance, α = 0.77 for compr

Self-Efficacy Scale for Normal Birth

Participants' perceptions of control and support during childbirth will be assessed using the Perceived Control and Support During Childbirth Scale developed by Ford, Ayers, and Wright in 2009. The Perceived Control and Support During Childbirth Scale is a scale developed to assess women's perceptions of control and support during childbirth in the postpartum period.The scale consists of three sub-dimensions: internal control, external control, and perceived support, and contains a total of 33 items. The PCS, which has a five-point Likert scale, is rated from "1 = Strongly disagree" to "5 = Strongly agree". The minimum possible score on the scale is 33, and the maximum score is 165. Higher scores indicate that the individual felt more control and perceived more support during childbirth. In the Turkish reliability and validity study of the scale, the Cronbach's alpha coefficient was reported as 0.95.

Perceived Control and Support in Childbirth Scale

Participants' self-efficacy levels will be assessed using the Self-Efficacy Scale for Normal Delivery, developed by Chu et al. in 2017. This scale is an important assessment tool, particularly for determining women's attitudes towards normal delivery and their level of self-confidence during the prenatal period. The scale consists of 9 items, each scored from 0 (no confidence at all) to 10 (very confident). Thus, the scale offers 11 different score options for each item. The total scores that can be obtained from the scale range from 0 to 90, with higher scores indicating a high level of self-efficacy belief in normal delivery. Cronbach's alpha coefficient was reported as 0.994 for the 2nd trimester; 0.956 for the 3rd trimester; and 0.980 for the entire scale. The Turkish adaptation, validity, and reliability study of the Self-Efficacy Scale for Normal Birth was carried out by Kahraman and Alparslan in 2022.
