Supporting its young members has been a key priority of the International Association for the Study of Pain (IASP) for the past 5 decades. The IASP, along with its federations, chapters, and special interest groups, has provided benefits to its trainee and early career members for their career development. This article summarizes various key IASP initiatives and benefits offered to IASP members and how these benefits have positively impacted their careers, including examples from the authors of this article. Suggestions are made for future directions that the IASP could implement to enhance the value provided to its trainee and early career members, which will in turn contribute to IASP achieving its mission to stimulate and support the study of pain and to translate that knowledge into improved pain relief worldwide.

Observing someone experience pain relief or exacerbation after an intervention may induce placebo hypoalgesia or nocebo hyperalgesia. Understanding the factors that contribute to these effects could help in the development of strategies for optimizing treatment of chronic pain conditions. We systematically reviewed and meta-analyzed the literature on placebo hypoalgesia and nocebo hyperalgesia induced by observational learning (OL). ⋯ Overall, the meta-analysis demonstrates that OL can shape placebo hypoalgesia and nocebo hyperalgesia. More research is needed to identify predictors of these effects and to study them in clinical populations. In the future, OL could be an important tool to help maximize placebo hypoalgesia in clinical settings.

Since it was founded, the International Association for the Study of Pain (IASP) has been at the forefront of improving pain research, education, and effective pain management in both developed and developing countries. As IASP activities progressed, major differences between the practice of pain management, education, and research in developed countries compared with developing countries were identified. This led to areas of focus by IASP that included pain education to address poor knowledge of pain assessment and treatment, prioritization of pain management by governments and official national legislation and programs, and availability of pain treatments (especially potent analgesics). ⋯ Many IASP chapters in developing countries have established collaborations with groups from developed countries, whereas IASP also implemented other innovative approaches including the developing countries working group, educational grants, pain camps, and multidisciplinary pain hubs with toolkits to develop pain experts for regions in the developing world. Thus, the influence of IASP in many developing countries has had a multiplier effect on the progress made in effective pain management, education, and research. Nonetheless, challenges remain and include better integration of pain management, education, and research in national health systems and academic programs for health professionals.

This article highlights advances in basic science preclinical pain research, clinical research, and psychological research occurring over the 50 years since the International Association for the Study of Pain was founded. It presents important findings and key trends in these 3 areas of pain science: basic science preclinical research, clinical research, and psychological research.
