The goal of this clinical trial is to learn if a structured motivational interviewing program based on the Five-Step (5A) model works to promote healthy lifestyle behaviors in individuals at high risk of obesity. It will also learn about the effects on anthropometric measurements and physical activity levels. The main questions it aims to answer are:
Participants will:
Exclusion Criteria:
Experimental Group: Participants receive five structured motivational interviewing sessions over a three-month intervention period, with anthropometric measurements repeated at each session.
Behavioral: Motivational Interviewing
Control Group: Participants are monitored with standard routine care over a three-month intervention period without motivational interviewing sessions.
Motivational Interviewing Techniques and the Five-Step (5A) Model Framework
Change in Body Mass Index (BMI)
Changes in body mass index measured in kg/m² from baseline to the end of the intervention period.
Time frame: Until the end of five motivational interviews that will take place over a three-month period
Change in Body Weight
Changes in body weight measured in kilograms (kg) from baseline to the end of the intervention period.
Time frame: Until the end of five motivational interviews that will take place over a three-month period
Change in Waist Circumference
Changes in waist circumference measured in centimeters (cm) from baseline to the end of the intervention period.
Time frame: Until the end of five motivational interviews that will take place over a three-month period
University of Rhode Island Change Assessment (URICA) Scale Score
Changes in readiness score measured by the 32-item University of Rhode Island Change Assessment (URICA) scale. Each item is rated on a 5-point Likert scale ranging from 1 to 5, where higher scores indicate greater readiness for change.
Time frame: Until the end of five motivational interviews that will take place over a three-month period
Change in Physical Activity Level
Changes in physical activity levels measured by the General Practice Physical Activity Questionnaire (GPPAQ) instrument from baseline to the end of the intervention period, categorizing participants into four activity levels (active, moderately active, moderately inactive, and inactive) based on occupational physical activity and exercise/cycling hours.
Time frame: Until the end of five motivational interviews that will take place over a three-month period.
Qualitative Assessment of Motivational Factors
Qualitative themes encompassing awareness, motivational barriers, health responsibility, and self-efficacy assessed via in-depth interviews.
