    (Maltepe Üniversitesi, Sağlık Bilimleri Enstitüsü, 2018-09) Semiz, Demet; Sağlam, Rabia
    This methodological study aimed at evaluating the validity and reliability of the Symptom-Management Self-Efficacy Scale Related to Chemotherapy in Breast Cancer. The study was conducted at the chemotherapy unit of a public hospital located in Istanbul between November 2017 and September 2018. No sampling method was used for the study and 248 female subjects who met the inclusion criteria and agreed to participate in the study were included. The study data were collected by way of face-to-face interviews using a Patient Description Form and the Symptom-Management Self-Efficacy Scale Related to Chemotherapy in Breast Cancer. Language, content and construct validity and reliability analyses were used to assess the validity and reliability of the scale. The language validity of the Symptom-Management Self-Efficacy Scale Related to Chemotherapy in Breast Cancer was analyzed using the translation and back-translation method and its content validity was verified through expert views. The scale was presented to 12 experts for their views on its content validity. After assessing the content validity using the Davis technique together with expert views, the CVI value of the items of the Symptom-Management Self-Efficacy Scale Related to Chemotherapy in Breast Cancer was found to be 0.912. Scale factor value changed between 0.30-0.80. Just as the original version it was evaluated as three lower dimensional by factor analysis . As a result of the internal consistency analysis of the scale, the total item score correlations were found to be sufficient and its Cronbach alpha coefficient to be 0.905. In conclusion, the Symptom-Management Self-Efficacy Scale Related to Chemotherapy in Breast Cancer was found to be a valid and reliable measurement tool in Turkish language.

    Validity and Reliability of the Symptom-Management Self- Efficacy Scale for Breast Cancer Related to Chemotherapy
    (Galenos Publ House, 2022) Semiz, Demet; Saglam Aksut, Rabia
    Objective: Since breast cancer (BC) is one of the most common cancer types among women, it is very important for nurses to assess symptom-management and self-efficacy of patients during chemotherapy treatment. This study was carried out to examine the validity and reliability of the symptom-management self-efficacy scale for BC related to chemotherapy. Methods: The study sample of this methodological research consisted of 248 women receiving chemotherapy treatment due to breast cancer in a public hospital in Istanbul between November 2017 ans March 2018. Translation-back translation method was used to assess the language validity of the scale. Kaiser-Mayer-Olkin and Bartlett's tests were applied to evaluate the sampling adequacy and the suitability of the data for factor analysis. Results: The content validity of the Turkish form was 0.912; Cronbach alpha coefficient of the scale was 0.905. The factor loads of all the items belonging to the scale were above 0.40, and explained variance for the scale was as follows; 16,284 for the problem-solving sub-dimension; 13,517 for the sub-dimension of managing problems in emotional and interpersonal relationships, and total explained variance of the scale was found to be 46,944. For this reason, no items were removed from the scale and the scale was accepted as having 3 sub-dimensions as it was in the original. Conclusion: Findings obtained from this study showed that the Turkish version of the scale was valid and reliable and could be used in research and clinical practice in Turkey.
