Participants in this group will engage in 15-minute progressive muscle relaxation (PMR) exercises guided by the researcher for three consecutive days (once per day). To promote continued practice, participants will receive an audio recording of the PMR session, narrated by the researcher. After the initial three supervised sessions, they will be asked to listen to this recording twice a week and log their practice on a provided tracking sheet. The researcher will follow up with participants via phone calls to monitor compliance.

Participants will undergo 15-minute VR-assisted PMR sessions for three consecutive days (once per day) under the researcher's supervision. During the VR sessions, participants will be exposed to relaxing nature scenes and sounds while simultaneously engaging in researcher-guided progressive muscle relaxation (PMR) exercises. After the initial three sessions, participants will receive an audio recording of the PMR session and will be instructed to listen to it twice a week, logging their sessions. The researcher will conduct phone follow-ups to ensure adherence.

Participants in the control group will not receive any relaxation intervention and will continue their usual daily routines.

Participants engage in progressive muscle relaxation exercises using a virtual reality headset that provides immersive visual and auditory relaxation content. Sessions are conducted under researcher supervision, followed by self-guided practice using an audio recording.

A researcher-developed questionnaire designed to collect sociodemographic and obstetric data based on the literature.

Tracked using a researcher-developed follow-up form, including maternal vital signs and Non-Stress Test (NST) parameters.

Developed by Beck, Steer, Epstein, and Brown in 1988 and adapted into Turkish by Ulusoy et al. in 1998, this 21-item Likert-type scale measures anxiety levels. Each item is scored between 0 and 3, with total scores ranging from 0 to 63. Higher scores indicate higher levels of anxiety. The Turkish version has a Cronbach's alpha of 0.93, indicating high internal consistency. Factor analysis suggests two subscales: Subjective Symptoms and Somatic Symptoms.

Originally developed by Takeishi et al. in 2011 in Japan and later revised by Nakamura et al. in 2015 to a 15-item version, this scale measures prenatal comfort across five subscales: Partner's Role in Fatherhood, Fetal Interaction, Social Support, Maternal Role Adaptation, and Awareness of Pregnancy Changes. The 6-point Likert-type scale ranges from 0 (strongly disagree) to 5 (strongly agree), with higher scores indicating higher comfort levels. The scale has a Cronbach's alpha of 0.95 in the original study and 0.82 in the Turkish adaptation.
