Validation of the PCQ-5: A Short Form to Measure State Positive Psychological Capital
验证了一个仅含5个条目的积极心理资本量表PCQ-5，该量表在四个国家的样本中表现出良好的信度和效度，可用于高效测量员工积极性。
Positive psychological capital (PsyCap) is a key measure of workplace positivity, yet its organizational impact may be somewhat limited by current measurement practices. Given its state-like and malleable nature, organizations need accurate yet brief measures to allow for repeated measurement of PsyCap. A very short PsyCap instrument could be used in various ways by organizations to measure and track employee positivity, thus enabling management to make decisions with more insight. Similarly, for researchers, a much shorter scale could dramatically improve research efficiency and response rate, opening up new perspectives in PsyCap research. In this paper, initial evidence is provided for the validity of a short PsyCap measure across multiple samples of working adult populations ( N = 1331 in total) from four different countries (United States, China, Germany, and Hungary). Consistent with prior research, we propose a five-item PsyCap measure, the PCQ-5, consisting of one item from the dimensions of self-efficacy, resilience, and optimism and one item for each facet of the hope dimension (agency and pathways). The proposed PCQ-5 shows internal consistency reliability and good fit for a single factor global PsyCap model across all samples. Moreover, like the PCQ-24, the PCQ-5 is associated with meaningful workplace outcomes such as job performance, job satisfaction, OCBs, voice, and helping behaviors, and it is negatively related to deviant behaviors like CWBs.
