Adoption of effective protection behaviors (SPB) is of paramount importance, particularly among individuals previously diagnosed with non-melanoma skin cancer (NMSC), since they have a considerably higher risk of new NMSC and malignant melanoma; the most lethal form of skin cancer (Nahar et al., 2015). The objective of the current study was to examine the utility of the information-motivation-behavioral skills (IMB) model in measuring and predicting SPB among people who have had NMSC. For this descriptive cross-sectional study, a convenience sample of NMSC patients was recruited at the University of Mississippi Medical Center between July 2015 and April 2016. Inclusion criteria were as follows: a) patients diagnosed with NMSC and b) ages 18 years or older. Participants were excluded from this study if they had severe physical or cognitive impairments. Demographic information and IMB model variables (i.e., knowledge, perceived risk, attitudes, social support, self-efficacy, and SPB) were assessed using a 114-item content valid questionnaire. A total of 311 NMSC patients participated in this study. The mean age of the participants was 64.12 (±12.02) years. Majority (58.8%) of the participants were males. Between 14% and 43% of the participants reported always engaging in SPB while outdoors. Internal consistency reliabilities for the subscales of IMB model ranged from acceptable to excellent (Cronbach’s α = 0.70-0.95). Confirmatory factor analysis verified construct validity and confirmed that the set of constructs in a hypothesized IMB model provides an acceptable fit to the empirical data (X2 = 287.618 [df = 133], p < 0.001; RMSEA = 0.06; CFI = 0.93; TLI = 0.91; SRMR = 0.05). Path analysis shoSPB was directly predicted by self-efficacy (β = 0.5, p < 0.001) and social support (β = 0.199, p = 0.010). Another important finding to emerge from the analysis is that SPB was indirectly predicted (through self-efficacy) by social support (β = 0.160, p < 0.001) and attitudes (β = 0.192, p = 0.001). The explained variances for self-efficacy and SPB were 43% and 35.4%, respectively. Findings of this study demonstrated partial utility of IMB model in predicting SPB among NMSC patients. safety intervention programs are needed for NMSC patients and should be especially focused on improving motivation (attitudes and social support) and behavioral skills (self-efficacy).
