A Study on the Services Motivating Instructional Designers in Higher Education to Engage in Professional AssociationsThe purpose of this research was to identify the professional association services relevant to instructional design professionals working in institutions of higher education. A conceptual framework connecting professional association services to the existing research on the leadership, career development, and networking of instructional designers in higher education is provided. Based on this conceptual framework and an existing instrument, we provide the design, development, and adjustment of a survey to measure professional association services relevant to instructional designers in higher education; and provide the preliminary validity and reliability evidence of this survey on an administration with N = 217 instructional designers working in higher education. We titled this survey the Instructional Designer in Higher Education Professional Association Survey (IDHEPAS). The cross-sectional data were analyzed using exploratory factor analysis, descriptive statistics, internal consistency reliability, and correlation analyses. The analyses resulted in eight internally consistent factors explaining approximately 71% of the variability in these data: 1) Professional networking services, 2) Growth and advocacy services, 3) Professional communication services, 4) Ancillary discount services, 5) Leadership and mentoring services, 6) Relevant literature services, 7) Training and credentialing services, and 8) Vendor and continuing education services. These findings are discussed in detail, and recommendations for future research and practice are provided. The IDHEPAS was found to be a sound measurement tool for the stated purpose.
