The study was set up as a first exploration of the predictive role of human service professionals' (i.e., teachers and healthcare professionals) psychological capital (PC) in their perception of work experiences and some core aspects of their own work, such as their efficacy to instill positive resources in their clients, the positive representation of their work and of the results that they can obtain, and positive beliefs about their career growth. Three hundred and eight Northern Italian human service professionals were involved, of which 163 were elementary school teachers of inclusive classrooms and 145 were healthcare professionals in day and residential centers. The regression analyses which were carried out-controlling for age, gender, years of work experience and the typology of the human service jobs-confirmed the predictive role of PC in the efficacy to instill positive resources in one's clients, the positive representation of the work and of the results that can be obtained, and positive beliefs about career growth. These results have important implications for practice, and they emphasize that specific interventions aimed at promoting human service professionals' PC may positively impact the effectiveness of their actions for the adaptation and psychosocial development of their clients.
