The Perceived Impact Scale (Meyer et al., 2016) was developed to measure inmates' self-reports of the impact that a life span human development class had on their level of knowledge, abilities, and other characteristics, such as self-awareness, emotional growth, and confidence. Following completion of the first class, a focus group was held with inmates who had completed the class to determine in what ways it had impacted them. There were no scales available in the literature to measure the array of constructs they identified as having changed so a scale was created. A sample of women serving long-term sentences provided two ratings on the last day of class, one for their recalled assessment of themselves on each construct before the course and one for their current assessment on each construct after the course. In addition, at the end of the scale, the women were asked to answer the item, "Overall, how has this human developmental class affected your sense of purpose" on a scale from 1 to 5. Psychometrics specific to this 37-item scale were not presented by the authors. (PsycTests Database Record (c) 2022 APA, all rights reserved)
