Change in anxiety symptoms
Self-Rating Anxiety Scale (SAS) Anxiety symptoms were assessed using the 20-item Zung Self-Rating Anxiety Scale (SAS). Each item is rated from 1 to 4. The raw total score ranges from 20 to 80 and is multiplied by 1.25 and rounded to obtain a standard score ranging from 25 to 100. The minimum possible standard score is 25 and the maximum is 100. Higher scores indicate more severe anxiety symptoms. A standard score of 50 or higher indicates the presence of anxiety symptoms. The standard score was used in the analysis.
Time frame: Baseline and immediately after the 8-week intervention
Change in depressive symptoms
Self-Rating Depression Scale (SDS) Depressive symptoms were assessed using the 20-item Zung Self-Rating Depression Scale (SDS). Each item is rated from 1 to 4. The raw total score ranges from 20 to 80 and is multiplied by 1.25 and rounded to obtain a standard score ranging from 25 to 100. The minimum possible standard score is 25 and the maximum is 100. Higher scores indicate more severe depressive symptoms. A standard score of 53 or higher indicates the presence of depressive symptoms. The standard score was used in the analysis.
Time frame: Baseline and immediately after the 8-week intervention
Change in fear of childbirth
Childbirth Attitudes Questionnaire (CAQ) Fear of childbirth was assessed using the 16-item Childbirth Attitudes Questionnaire (CAQ). Each item is rated from 1 to 4, producing a total score ranging from 16 to 64. The minimum possible total score is 16 and the maximum is 64. Higher scores indicate greater fear of childbirth. Scores of 16-27 indicate no fear, 28-39 mild fear, 40-51 moderate fear, and 52-64 severe fear. A total score of 28 or higher indicates the presence of fear of childbirth.
