Show Summary Details


Long-term studies aiming to assess changes over time require a careful description of measurement techniques, consistent questionnaire design, the training of personnel undertaking the measurements, and the quality control of all procedures. A further requirement is the maintenance of good communications within the team and with helpers in a study, which included the participation of many primary schools throughout England and Scotland. These objectives were achieved by a team of eight people which arranged annual activities preparing questionnaires, forms, explanatory manuals, and fieldwork activities, and the data collected was processed within the year. The study maintained a response rate of approximately 80% over its twenty-three years of existence and around of 75% for measurements which required explicit parental consent. The study was notable for the very low number of complaints received, which were solved locally or by the team co-ordinators.
