Objective: Assessing nursing self-efficacy could be strategic to sustain nursing competence. This study aimed to develop and validate the nursing self-efficacy scale for managing cancer treatment-induced cardiotoxicity (NSS-CTC).Data Sources: An exploratory mixed-method study was performed by including two main phases. The first comprised the developmental tasks to generate the initial pool of items, including a literature review and a consensus meeting based on a nominal group technique. The second phase initially involved an external panel of experts in assessing the content validity of the novel scale, followed by a cross-sectional data collec-tion to perform exploratory factor analysis by employing a multicenter and convenience sampling approach.

Its two plausible domains were labeled knowledge-related self-efficacy (Cronbach's a = 0.924) and practice-related self-efficacy (Cronbach's a = 0.937); the factor analy-ses in both samples showed adequate fit to sample statistics.

Abstract
Objective: Assessing nursing self-efficacy could be strategic to sustain nursing competence. This study aimed to develop and validate the nursing self-efficacy scale for managing cancer treatment-induced cardiotoxicity (NSS-CTC).Data Sources: An exploratory mixed-method study was performed by including two main phases. The first comprised the developmental tasks to generate the initial pool of items, including a literature review and a consensus meeting based on a nominal group technique. The second phase initially involved an external panel of experts in assessing the content validity of the novel scale, followed by a cross-sectional data collec-tion to perform exploratory factor analysis by employing a multicenter and convenience sampling approach. The most plausible psychometric structure derived from the exploratory factor analysis was tested with a confirmatory factor analysis using a second data collection round on another sample enrolled with a multi-center and convenience sampling approach. Internal consistency was assessed using Cronbach's alfa.Conclusion: The NSS-CTS is a novel 15-item self-report measure for assessing nurse self-efficacy in dealing with cancer treatment-related cardiotoxicity. Its two plausible domains were labeled knowledge-related self-efficacy (Cronbach's a = 0.924) and practice-related self-efficacy (Cronbach's a = 0.937); the factor analy-ses in both samples showed adequate fit to sample statistics.
