About this study

Official title: Motivational Intervention Through the Generation of an Interpersonal Plan About Nutrition and Physical Exercise Study (IMAGINE Study), a Randomized Controlled Trial With Obese and Overweight Adolescents in Portuguese High Schools

The objective of the study is to investigate the efficacy of motivational interview intervention with adolescent students at a school environment on the adhesion to a therapeutic plan to loose weight.

Read the detailed description

Motivational interview (MI) is a style of communication collaborative, objective-directed, with special attention to change talk.

The present study's main objective is to investigate the efficacy of a MI intervention in adolescents with weight excess, in a school setting, over their motivation to adhere to a health lifestyle plan of dietary habits and physical exercise.

Secondary objectives are to investigate the effect of MI over self-concept, quality of life, depressive symptoms, anxiety symptoms, body mass index, abdominal circumference and blood pressure.

Registry Procedures Data on anthropometric parameters is recorded in data collection sheet and stored in individual files, which are available for monitoring procedures and for auditing by the Metabolic and Food Behavior Disorders Scientific Committee.

Data Checks Data checks will be performed to compare data entered into the registry against predefined rules for range or consistency with other data fields in the registry

Source Data Verification All the data will be checked to assess accuracy, completeness, or representativeness of registry data by comparing the data to external data sources: audio-taped interviews, paper case report forms and paper case self-report forms. All the registries will be stored during five years after study completions according to the Medical Faculty of Lisbon norms.
