Previous studies of environmental support resources for school-aged children have mainly focused on individuals giving social support. This study reports the findings of support resources via the Photo Projective Method (PPM), which is an approach to understand children’s perspective on them and psychological environments through photographs focusing on friendship. Data were collected from two public elementary schools in Japan, and 63 children (aged 11-12) participated in our research in 2008 and 2009. After the PPM, semi-structured interviews were conducted where the participants were asked to choose their favorite photos and talked about the subjects photographed. The photographs were classified into “persons”, “places”, “animals”, and “objects”. Persons were the most photographed, particularly 69% of the participants photographed their friends. As for the relationship between the children and their resources, 11 categories appeared by KJ method: companionship, commitment, intimacy, perceived-being-accepted, personal reminiscence, feeling of relaxation, having positive emotions, being together, mood enhancement, affection, and indirectly relationship. Finding suggested the significance of using ecological models to comprehend support resources for the children. Discussion centers around psychological education and assessment tool to support children at school.
