Decision-making ability, psychopathology, and brain connectivity.

ABSTRACT: Decision-making is a cognitive process of central importance for the quality of our lives. Here, we ask whether a common factor underpins our diverse decision-making abilities. We obtained 32 decision-making measures from 830 young people and identified a common factor that we call "decision acuity," which was distinct from IQ and reflected a generic decision-making ability. Decision acuity was decreased in those with aberrant thinking and low general social functioning. Crucially, decision acuity and IQ had dissociable brain signatures, in terms of their associated neural networks of resting-state functional connectivity. Decision acuity was reliably measured, and its relationship with functional connectivity was also stable when measured in the same individuals 18 months later. Thus, our behavioral and brain data identify a new cognitive construct that underpins decision-making ability across multiple domains. This construct may be important for understanding mental health, particularly regarding poor social function and aberrant thought patterns.

Project description:BackgroundNursing ethical decision-making ability is a core competency of nurses. However, no tool has been developed to measure the ethical decision-making ability of nurses in China. Therefore, we aimed to develop a nursing ethical decision-making ability scale (EDMAS) and assess its validity and reliability.MethodsA literature review, qualitative study, and the Delphi method were employed to identify the most common ethical dilemmas and original scale items. A cross-sectional study was conducted to evaluate the items. The reliability and validity of the scale were evaluated. Exploratory factor analysis (EFA) was employed to investigate the factor structure based on data from group 1 (N = 404). Confirmatory factor analysis (CFA) was employed to assess the construct validity based on the data from group 2 (N = 503). Convergent validity was evaluated using composite reliability (CR) and average variance extracted (AVE). Discriminant validity was assessed by analyzing the maximum shared variance (MSV). We invited 15 experts to evaluate the content validity of the EDMAS. This study was conducted between December 2021 and January 2023.ResultsWe defined 4 nursing ethical dilemmas and 71 original items. We deleted 4 items during the screening process. Additionally, 3 items were deleted from the EFA. The EFA revealed that the EDMAS with 64 items had a four-factor structure (ethical sensitivity, motivation, judgment, and action), accounting for 56.05% of the total variance. The CFA revealed that χ2/df = 1.291, RMSEA = 0.024, CFI = 0.976, TLI = 0.974, NFI = 0.902, and IFI = 0.976. The CR values were between 0.945 and 0.964. The AVE values were between 0.583 and 0.588. The MSV values were between 0.533 and 0.572. The value of I-CVI varied from 0.867 to 1.000, and the S-CVI/Ave was 0.965. The Cronbach's of the scale was 0.982. The test-retest reliability of the EDMAS was 0.982.ConclusionEDMAS is a reliable and valid tool for evaluating nurses' ethical decision-making ability and enhancing its ability through ethics training programs.
