This manual presents information on three instruments designed for surveying mental health problems in schools. Part I describes the instruments, which are two questionnaires called the School Problem Area Survey--Staff, and the School Problem Area Survey--Students, and a guide to be used in interviews, called the Demographic Information Form as well as procedures for their use. The questionnaires are designed to obtain information about potential problems in schools which may be amenable to treatment by mental health indirect services program carried out by mental health consultants and members of the schools' staff. The guide should help consultants and principals gain a comprehensive picture of their schools which would aid them in problem solving. Part I, in addition, contains outlines on the necessary steps to be taken to obtain the interview and questionnaire data, statistical procedures involved in data analysis and guidelines for the assigning of priorities for the interpretation of data from three sources. Part II is an exploration of the general meanings of reliability and validity. It is concluded that measures of internal consistency are the most appropriate measures of reliability. Face validity and demonstrations of the utility of the instruments seem most appropriate in addressing the issue of validity. (Author/BJG)
