Reliability and validity of the Turkish version of the Individual-Level Abortion Stigma Scale: a methodological study

ObjectivesThe aim of this study was to assess the reliability and validity of the Turkish version of the Individual-Level Abortion Stigma Scale.SettingThree hospitals affiliated to Public Hospitals Union General Secretariat in Manisa, a city located in Western Turkey.DesignThis was a methodological study.ParticipantsA total of 230 women aged 22–49 years who previously underwent abortion and volunteered to participate in the study.Primary and secondary outcome measuresData analysis was performed using the SPSS and LISREL software. The Content Validity Index was calculated based on the values obtained from expert opinions. In the reliability analysis, Cronbach’s alpha values were calculated for the overall scale and its subscales. To test the stability of the scale over time, the scale was readministered to 30 women in the study 15 days later and the test–retest values (Pearson’s correlation coefficients) were determined. In the validity analysis, the exploratory and confirmatory factor analyses were performed. In the exploratory factor analysis, the principal component analysis was performed using the varimax rotation and the factor loading of the scale was examined. Confirmatory factor analysis was performed to investigate the item-factor construct of the scale.ResultsThe Content Validity Index was calculated as 0.86. The Cronbach’s alpha values ranged between 0.83 and 0.94. The item-total correlation coefficients ranged between 0.36 and 0.72, and the test–retest reliability was 0.96 for the overall scale and its subscales (p<0.05). The total variance revealed by five factors was 75%. Confirmatory factor analysis of the scale revealed an acceptable compliance level (root mean square error of approximation=0.092, χ2/df=2.91, Goodness of Fit Index=0.831, Comparative Fit Index=0.928, p<0.001).ConclusionsThe results suggest that this scale has the potential for use in research and clinical settings to measure abortion stigma among women.

Background: Breast cancer patients need to be treated not only physically and emotionally but also spiritually. Hence, the assessment of the spirituality of patients is essential to provide holistic nursing care. However, there was no culturally valid and reliable instrument that measures spirituality among Filipino women with breast cancer.Objective: The study was conducted to determine the psychometric properties of the spiritual index of well-being among Filipino women with breast cancer.Methods: A descriptive cross-sectional design was utilized in the study, and a sample of 170 Filipino women with breast cancer were included. The World Health Organization guidelines were used to translate the original instrument to Filipino, and content validity was computed using the Davis technique. Also, confirmatory factor analysis with maximum likelihood estimation was performed to assess the construct validity of the instrument. Cronbach’s α and item-total correlations were done to assess the internal consistency of the Filipino version of the spiritual index of well-being.Results: The Filipino version of the spiritual index of well-being had an item content validity index (I-CVI) ranging from 0.86 to 0.92 and a scale content validity index (S-CVI) of 0.95. The confirmatory factor analysis (CFA) showed factor loadings of 0.42 to 0.72. Also, the CFA model revealed a 𝜒2/df = 2.51, root mean square error of approximation= 0.074, comparative fit index= 0.091, goodness of fit index=0.98, Tucker-Lewis index= 0.93, incremental fit index= 0.91, and standard root mean square residual== 0.072.Conclusion: The Filipino version of the spiritual index of well-being was cross-culturally valid and reliable in measuring the spiritual index of well-being among Filipino women with breast cancer.

Objective:The study was carry out in order to evaluate the validity and reliability of Paternal-Antenatal Attachment Questionnaire. Method: Research was made with 155 expectant fathers who attended routine pregnancy controls with their partners in a obstetric and gynecology clinic in Izmir, were literate, aged 18 or older and without any health risk of fetus. Data were collected by information form and Paternal-Antenatal Attachment Questionnaire by developed Condon in 1993. İnitially the language validity of the scale was made by using the translation-back translation method with five experts. The Turkish version of the scale was presented to the opinion of ten experts using Davis technique for the content validity and content validity index was calculated. Factor structure was tested.by exploratory and confirmatory factor analysis. In the confirmatory factor analysis, structural equation modelling fit indices were examined. Findings: Content validity index of each item was determined to vary between .80–1.00. As a result of exploratory factor analysis, a two-factor structure explaining 36.54% of the total variance of the scale was determined. Factor loads vary between 0.41-0.84 in the one dimension and 0.30-0.82 in the another dimension. Confirmatory factor analysis showed that this two-factor structure was appropriate (RMSEA 0.044, GFI 0.912, AGFI 0.880 χ2/df ise 1.298(p=0.025). The Cronbach’s alpha value of scale was 0.79. Conclusions: The two-factor structure of the scale, as “attachment quality” and “time spent of attachment mode” is valid and reliable for the use of expectant fathers’ Turkish society.
