Development and psychometric evaluation of the Caregiver Caregiving Self‐Efficacy Scale for family members with oral cancer

Aim The aim of this study was to develop and initially assess the psychometric properties of the Caregiver Caregiving Self‐Efficacy Scale—Oral Cancer (CSES‐OC). Methods In total, 28 items in the Caregiver Caregiving Self‐Efficacy Scale—Oral Cancer were originally employed for a reliability and validity test based on expert suggestions and qualitative findings. The Cronbach's alpha coefficient and test–retest reliability were evaluated with the pilot sample, which included 30 caregivers. The main test, which included 107 caregivers during May 2016 to 2018, was used to execute the exploratory factor analysis (EFA) and concurrent validity. Results The results of the main test showed a Cronbach's alpha coefficient of .95 for the revised 18‐item total scale after EFA. Four factors (acquiring resources, managing sudden and uncertain patient conditions, managing patient‐related nutritional issues and exploring and making decisions on patient care) were classified from EFA of the Caregiver Caregiving Self‐Efficacy Scale—Oral Cancer. The r coefficient was .59 (P
