Abstract OBJECTIVE: The objective was to examine the efficacy of adding a technology-based program to an in-person, behavioral weight loss intervention. RESEARCH METHODS AND PROCEDURES: Fifty-seven subjects (BMI=33.1+/-2.8 kg/m2; age=41.3+/-8.7 years) participated in a 12-week intervention with random assignment to Standard In-Person Behavioral Weight Control Program (SBWP) or Intermittent or Continuous Technology-Based Program (INT-TECH, CON-TECH). SBWP subjects received seven individualized weight loss sessions encouraging dietary and exercise modifications. INT-TECH and CON-TECH subjects received all SBWP components; additionally, these groups used a SenseWear Pro Armband (BodyMedia, Inc.) to monitor energy expenditure and an Internet-based program to monitor eating behaviors. These features were used by INT-TECH subjects during weeks 1, 5, and 9 and CON-TECH subjects weekly throughout the intervention. RESULTS: Intent-to-treat analysis revealed weight loss of 4.1+/-2.8 kg, 3.4+/-3.4 kg, and 6.2+/-4.0 kg, for SBWP, INT-TECH, and CON-TECH groups, respectively (CON-TECH>INT-TECH, p
