After a period of rapid growth in its scientific foundations and professional applications, health psychology has entered the mainstream. With this increasing acceptance and interest comes the likely prospect that practitioners without formal training in clinical health psychology will be interested in expanding their work to include medical populations and settings. C. D. Belar et al. (2001) provided an invaluable guide to self-assessment and selfstudy to help bridge this potentially worrisome gap in training. However, lessons from the first 25 years of work in the field suggest that training in this subdiscipline is complex and demanding and sometimes may be beyond the scope of self-directed education. Although the suggested approach is excellent, the field should evaluate its effectiveness and support it with additional continuing education resources.
