A method of performing a structured collection procedure of an individual which helps the individual change a current behavior to a target behavior, wherein the structured collection procedure means collection of data of a measurement procedure wherein a biomarker is measured under prescribed conditions of the structured collection procedure; said method comprising: providing a structured collection procedure and program instructions; and executing the program instructions on a device (18, 24, 25) which cause a processor (76, 102) of the device (18, 24, 25) to: personalize the structured collection procedure by requesting via a display (70, 108) of the device (18,24,25) goals (SX, MX, L) from the individual to define for events to be accomplished in the structured collection procedure one or more adherence criteria that the processor (76, 102) uses to determine whether each event was accomplished successfully and to define one or more exit criteria for ending the structured collection procedure, requesting via the display (70, 108) input from the individual regarding one or more motivators and/or barriers, and determining one or more interventions based on the input regarding the one or more motivators and/or barriers; the method further being characterized to: initiate a schedule of the events defined in the structured collection procedure upon one or more entry criteria being met; preferably wherein a schedule of the events defined in the structured collection procedure is initiated automatically upon the one or more entry criteria being met, provide the one or more interventions when the one or more adherence criteria for one of the events is not met; and end automatically the structured collection procedure upon the one or more exit criteria being met. providing a structured collection procedure and program instructions; and executing the program instructions on a device (18, 24, 25) which cause a processor (76, 102) of the device (18, 24, 25) to: personalize the structured collection procedure by requesting via a display (70, 108) of the device (18,24,25) goals (SX, MX, L) from the individual to define for events to be accomplished in the structured collection procedure one or more adherence criteria that the processor (76, 102) uses to determine whether each event was accomplished successfully and to define one or more exit criteria for ending the structured collection procedure, requesting via the display (70, 108) input from the individual regarding one or more motivators and/or barriers, and determining one or more interventions based on the input regarding the one or more motivators and/or barriers; the method further being characterized to: initiate a schedule of the events defined in the structured collection procedure upon one or more entry criteria being met; preferably wherein a schedule of the events defined in the structured collection procedure is initiated automatically upon the one or more entry criteria being met, requesting via a display (70, 108) of the device (18,24,25) goals (SX, MX, L) from the individual to define for events to be accomplished in the structured collection procedure one or more adherence criteria that the processor (76, 102) uses to determine whether each event was accomplished successfully and to define one or more exit criteria for ending the structured collection procedure, requesting via the display (70, 108) input from the individual regarding one or more motivators and/or barriers, and determining one or more interventions based on the input regarding the one or more motivators and/or barriers; the method further being characterized to: initiate a schedule of the events defined in the structured collection procedure upon one or more entry criteria being met; preferably wherein a schedule of the events defined in the structured collection procedure is initiated automatically upon the one or more entry criteria being met, provide the one or more interventions when the one or more adherence criteria for one of the events is not met; and end automatically the structured collection procedure upon the one or more exit criteria being met.
