The National Academy of Sciences stressed the need for a doctorally prepared workforce and earlier entry into doctoral study in nursing and the behavioral, social, and basic sciences. Social Cognitive Career Theory (SCCT) suggests that self-efficacy for career related skills informs career choices. Thus, increasing clinical research self-efficacy early in students' studies could increase their choice of a research career. To test interventions, a psychometrically sound measure of clinical research self-efficacy is needed.
We examined the psychometrics of the Clinical Research Appraisal Inventory-Short Form (CRAI-SF) in undergraduate and first-year graduate students (N = 268). This scale is a modification of the Clinical Research Appraisal Inventory, which measures physician-scientists' clinical research self-efficacy.
Content validity was supported by external review. Factor analysis revealed six factors explaining 75% of scale variance. Internal consistency of subscales and total scale ranged from .84 to .98. Differences in scores by gender (p = .016) and discipline of study (p = .000) supported construct validity.
The CRAI-SF is a useful measure of undergraduate and first-year graduate students' perceived clinical research self-efficacy.
美国国家科学院强调需要培养具有博士学位的专业人才，并鼓励护理专业以及行为科学、社会科学和基础科学专业的学生更早进入博士阶段学习。社会认知职业理论（SCCT）表明，与职业相关技能的自我效能感会影响职业选择。因此，在学生学习早期提高其临床研究自我效能感可能会增加他们选择从事研究职业的可能性。为了测试干预措施，需要一种心理测量学上可靠的临床研究自我效能感测量方法。
我们对本科学生和一年级研究生（N = 268）的临床研究评估量表简版（CRAI-SF）进行了心理测量学检验。该量表是对临床研究评估量表的修订版，用于测量医师科学家的临床研究自我效能感。
外部评审支持内容效度。因子分析揭示了六个因子，解释了量表方差的75%。分量表和总量表的内部一致性范围为0.84至0.98。性别得分差异（p = 0.016）和学科得分差异（p = 0.000）支持结构效度。
CRAI-SF是一种用于测量本科学生和一年级研究生临床研究自我效能感的有效工具。
