Design of a scale of adherence to medical treatments for the Colombian population

The objective of this study is to design and validate an instrument that allows assessing the probability of adherence in patients who are going to start medical treatment based on a biopsychosocial model. The instrument consisting of three areas was used: pharmacological indications or drug dosage, lifestyle change and social support. For the design and validation of the instrument, the sample consisted of 161 participants, 98 women (60.9%) and 63 men (39.1%), with ages between 18 and 64 years old (M = 26.63; SD = 0.75). For data processing, it was necessary to use the R Studio program and SPSS version 26. The results obtained proved that the test of adherence to medical treatment had a sample adequacy index by KMO of 0.924 and Bartlett's sphericity test of <0.01 which will be carried out by exploratory and confirmatory factor analysis, in addition a reliability of Cronbach's Alpha of 0.94 and of McDonald's Omega of 0.96 were found, being an adequate index for its use.
