Aim 3 - qualitative interviews
We will conduct qualitative interviews with 40 key informants to explore the future implementation of the multilevel physical activity intervention using the Consolidated Framework for Implementation Research as our conceptual model [Interviewers will follow a semi-structured interview guide with sections corresponding to each of the five CFIR domains: Outer Setting, Inner Setting, Intervention Characteristics, Characteristics of Individuals, and Process. The guide will allow for structured questions to be asked in all interviews, while allowing flexibility to probe or follow up on emerging topics. Interviews will be audiotaped, transcribed verbatim, and systematically read as they are being conducted to determine if information saturation has been reached. We will conduct a content analysis of the transcripts [Interview themes will also be compared among those public housing developments in which key informants gave higher and lower organizational readiness ratings during the housing manager interviews conducted at baseline. Then, following team-based coding, the preliminary coding structure will be shown to the entire research team to review our analysis decisions. Codes will be added, refined, and deleted during this process. To enhance the trustworthiness of the analysis, we will hold at least two peer debriefing meetings with the entire research team to show them the transcripts and the codes applied and ask for their feedback [
