The Robust Italian Validation of the Coping Humor Scale (RI-CHS) for Adult Health Care Workers

The Coping Humor Scale (CHS) is a seven-item tool widely used to assess the use of humor in coping with stressful situations. The beneficial effect of humor in buffering the impact of negative experiences has been investigated in several contexts and populations; for this reason, the CHS has been used in many languages, but its solid validation in Italian is still missing. Our study aimed at building a robust instrument to measure coping humor strategies among Italian health care workers, a category which has been particularly exposed to stressful situations in the last two years. The CHS translated into Italian was administered to a sample of 735 health care workers during the first wave of the COVID-19 pandemic in Italy. Confirmatory factor analysis and Rasch analysis were performed. As a result, a six-item Robust Italian Coping Humor Scale (RI-CHS) was validated and ready to use for future studies on Italian health care workers’ samples. This study gives evidence that our six-item solution works as a ruler (i.e., an instrument that meets the conditions of fundamental measurement in the context of the human sciences) to measure the degree to which Italian health care workers rely on humor to cope with stress
