In these turbulent, economically accountable times, with the dual demands for scientifically credible, evidenced-based and proven HRD approaches and techniques on one hand and the need to meet the needs of increasingly stressed and overworked employees facing bleak future prospects on the other hand, PCD seems ready and able to help meet the challenge. In the spirit of continuous improvement, as well as with the full realization that there are no silver bullets in an area so complex as effective HRD, I feel that with PCD we have a good start in the right direction. Yet an arduous journey certainly lies ahead. As to being infected by the silver bullet syndrome—that is, advocating that PCD is the answer—whenever I present my evidence-based PsyCap to HRD practitioner-scientists, I always carefully point out that our study results indicate correlations between PsyCap and outcomes are in the 0.25 to 0.5 range. For example, the Avey et al. (2011) meta-analysis mentioned earlier found the relationships between PsyCap and attitudes of satisfaction 0.54, commitment 0.48, and psychological well-being 0.57; PsyCap and organizational citizenship behavior 0.45; and PsyCap and multiple measures of performance 0.26. I emphasize that PsyCap accounts for only about 25% of the variance in attitudes and behaviors and 10% of performance. The remainder is made up of a myriad of other important variables, and even luck, in the complex HRD effectiveness equation. After giving practitioner-scientists this reality check based on research results, I then point out that these relationships are still statistically significant, better than chance. Unlike most of the other OB variables, PsyCap can be developed in employees and leaders and thus managed to provide competitive advantage. A cost-benefit analysis of PCD can also be made. Our PCD intervention studies so far only increases PsyCap 2% to 5% in the short 1- to 3-hour programs described earlier. However, again this is statistically significant compared to a randomly assigned control group that did not go through the training intervention. Moreover, our utility analyses clearly indicates this PCD has a very high return on investment, or what we call return on development (ROD; over 200% with real dollars in one application; for this and other examples, see Chapter 8 of Luthans, Youssef et al., 2007).
