Validation of an anxiety scale for prenatal diagnostic procedures

Abstract

OBJECTIVE: To perform a cross-cultural adaptation of the Prenatal Diagnostic Procedures Anxiety Scale questionnaire for application in the Brazilian cultural context. METHODS: The translation and back translation processes followed internationally accepted criteria. A committee of experts evaluated the semantic, idiomatic, experimental and conceptual equivalence, proposing a pre-final version that was applied in 10.0% of the final sample. Afterwards, the final version was approved for the psychometric analysis. At that stage, 55 pregnant women participated which responded to the proposed Brazilian version before taking an ultrasound examination at a public hospital in Santa Catarina, in the year of 2017. The Edinburgh Postnatal Depression Scale was used as an external reliability parameter. The internal consistency of the instrument was obtained by Cronbach’s alpha. Validation was performed by exploratory factorial analysis with extraction of principal components by the Kaiser-Guttman method and Varimax rotation. RESULTS: The Cronbach’s alpha value of the total instrument was 0.886, and only the percentage of variance from item 2 (0.183) was not significant. The Kaiser-Guttman criterion defined three factors responsible for explaining 78.5% of the variance, as well as the Scree plot. Extraction of the main components by the Varimax method presented values from 0.713 to 0.926, with only item 2 being allocated in the third component. CONCLUSIONS: The Brazilian version is reliable and valid for use in the diagnosis of anxiety related to the performance of ultrasound procedures in prenatal care. Due to the lack of correlation with the rest of the construct, it is suggested that item 2 be removed from the final version.

Transcultural adaptation of the Thirst Distress Scale (TDS) into Brazilian Portuguese and an analysis of the psychometric properties of the scale for patients on hemodialysis

“…Thirst intensity assessed via the VAS 23 (Table 5) found that most patients had moderate thirst. The mean score patients attained in the TDS-BR also indicated moderate thirst (17.87; ±7.87).…”

“…The study included 126 patients, a sample size characteristically seen in validation studies. [23][24][25][26] Data collection took place in the morning, afternoon, and evening shifts during HD sessions. The questionnaire included identification information and probed into etiology of CKD, time on HD, KT/V (a marker of quality of dialysis), comorbidities, body mass index (BMI), interdialytic weight gain (an indicator of fluid status), biochemical tests (transferrin, hemoglobin, ferritin, albumin, creatinine, pre-dialysis blood urea nitrogen, post-dialysis blood urea nitrogen).…”

Psycho-Emotional Impact of Anomaly Ultrasound Scan in Romanian Pregnant Women

“…Several studies focusing on prenatal anxiety have attempted to validate measures for assessing it; however, in Romania, this topic is underestimated and often overlooked, and this is why we intended to bring it into the health care providers' attention. This study aims to identify the specific issues in the national context to provide effective counseling and reduce anxiety and stress related to prenatal procedures [5].…”

The effect of education on anxiety of pregnant mothers before amniocentesis

“…The most important causes of anxiety in pregnancy are abortion, concern about the diagnosis of fetal abnormalities, fetal anaploidy, childbirth and postpartum complications, and acceptance of maternal responsibility. [ 8 9 10 ] According to the results of studies, the health status of the fetus is the most worrying factor for pregnant mothers. [ 11 ] Prenatal diagnosis of fetal malformations as a critical emotional event is anxious for women.…”
