1. We will convene an Expert Advisory Panel (EAP) with expertise in interpersonal and family caregiving processes and family psychotherapy to provide feedback on the OCM. The OCM represents an adaptation of previously established and reliable coding manuals developed for assessing interaction patterns in couples, families, and dementia caregiver research. Using an iterative process of refinement based on EAP feedback, pilot coding of video from five initial dyads, and feedback from those dyads we will use coding schemes originally developed for research and adapt them for clinical use. We will then recruit 15 additional dyads and videotape their interactions. Five Psychology Trainees will be trained on the OCM. The PI and pairs of Psychology Trainees will independently code each video to assess validity, reliability, and analyze qualitative data from semi-structured interviews of caregivers, care-recipients, and clinicians to assess acceptability and utility of the OCM.
