Published Research Evaluating InShape PPW


Like SPORT PPW, the InShape Prevention Plus Wellness program was evaluated in a number of research studies funded by NIH.  The results of these studies presented below were published in the Annals of Behavioral Medicine, Preventive Medicine, Journal of Adolescent Health, and Journal of American College Health.  

InShape PPW Study I

An initial study published in the Annals of Behavioral Medicine evaluated the InShape PPW program with over 300 college students and showed that, compared to a control group, young adults given the brief wellness-based lesson significantly (

  • reduced frequency and heavy use of alcohol,
  • reduced driving after drinking,
  • reduced initiation, quantity, and heavy use of marijuana,
  • increased hours of sleep, and
  • improved social and spiritual health-related quality of life. 

An analysis of the outcome data one year after baseline published in Preventive Medicine found that, compared to young adults in a control, those receiving InShape PPW continued to show significant ( 

  • reductions in driving after drinking,
  • increases in moderate exercise,
  • improvements in social health-related quality of life,
  • improvements in spiritual health-related quality of life, and
  • improvements in recent activity. 

InShape PPW Study II 

A subsequent study published in the Journal of American College Health evaluating InShape PPW in a computer-based format with 200 college-aged young adults found that, compared to a computer control, students given the InShape PPW wellness-based prevention lesson had significantly ( 

  • Less intentions to drink alcohol,
  • Less intentions to smoke cigarettes,
  • Less intentions to use marijuana,
  • More positive alcohol use social norms,
  • More positive cigarette smoking social norms, and
  • More positive marijuana use social norms. 

InShape PPW Study III

In yet another study published in the Journal of Adolescent Health, 155 students attending a university health clinic were randomized to receive either a health behavior contract, or an InShape tailored consultation with or without the contract ( 

College students receiving the InShape program showed significantly:

  • greater body image satisfaction compared to those receiving the contract only. 

These findings indicate that the InShape Prevention Plus Wellness program can also improve the body image of young participants.  

Together, these published research findings indicate that InShape PPW is effective in preventing and reducing substance use and related risk factors, and increasing health promoting behaviors among young adults.  It was also found to enhance various measures of health-related quality of life of college students.  Some of the positive outcomes from the brief InShape PPW lesson lasted for up to a year.  InShape PPW is an effective wellness-based prevention intervention in a single in-person lesson, and has potential as a self-administered computer-based prevention intervention.
