Learning Objective 1: describe the process for developing an instrument from empirical data.
Learning Objective 2: summarize the statistical methods used to establish the reliabilty and validity of the Instrument to Measure Adaptation of Elders Moving from Home to an ALF.
Methods: Instrument development, a complex process, involves specific and multiple steps. The steps outlined, illustrate the methodology used by a nursing professor to guide 6 doctoral nursing students to develop a 50 item questionnaire to measure the Adaptation of Elders Moving from Home to an Assisted Living Facility (ALF). The framework used follows the guidelines of Nunally (1978), DeVellis 2003), and Waltz, Strickland, and Lenz (2005). The development of the scale encompasses the critique of existing instruments, importance of a theoretical framework, distinction between constructs and measures, steps to design an item pool with format for measurement, assuring reliability and validity, administration of the developed instrument, and the process of validity and reliability analysis.
Results: The illustration of this process was the development and testing of the questionnaire: Adaptation of Elders Moving from Home to an Assisted Living Facility. This instrument has been developed and tested with elders in an ALF. The initial analysis for psychometric properties is complete and demonstrates a valid and reliable instrument that can be used to identify salient positive and negative factors of adaptation.
Conclusion: The confirmatory factor analysis demonstrated a valid and reliable instrument with three domains including; sustaining self, staying connected to others, and negotiating change.
