Such guidelines eliminated most of the positive constructs we considered when we were analyzing them for inclusion in PsyCap. This is why we published in a top research journal (Personnel Psychology; see Luthans, Avolio et al., 2007) the empirical validation of our PsyCap measure (PCQ) and demonstrated that PsyCap was a core construct that predicts outcomes better than any one of the four components that make it up. In another study, we also demonstrated that PsyCap adds significant variance to desired attitudinal and behavioral outcomes beyond the study participants’ demographics and established positively oriented OB constructs, such as core self-evaluations, personality traits, and person-organization and person-job fit (see Avey, Luthans, & Youssef, 2010). Besides this theory, research, and valid measurement foundation that is so pivotal to effective, sustainable HRD, the major contribution of PsyCap to HRD comes from these two criteria: (1) being statelike, open to development and (2) having causal impact on desirable attitudes, behaviors, and performance. These two PsyCap criteria can clearly serve to differentiate PCD from (1) much of positive psychology with its emphasis on more traitlike personality and character dimensions that are not open to development and that give little or no attention to performance impact; (2) much of widely recognized positively oriented OB constructs, such as positive affectivity and core self-evaluations, which also tend to be traitlike; (3) consulting firms such as Gallup’s well-known emphasis on hardwired strengths and talents that are not open to development; and (4) parallel positive approaches such as positive organizational scholarship,which also tends to focus more on traitlike constructs, such as compassion, forgiveness and energy, and thus again is not open to development.
