Active Comparator: Couple condition
Couples randomized to the couple condition will undergo the experimental manipulations and both partners will complete all study measures. Both members of the couple will be given body mass index (BMI) based on measurements taken during the intervention. Both will complete three surveys on paper and do some prompted planning and goal-setting together regarding weight loss through healthier eating and physical activity.
Behavioral: Mental Contrasting- Couple
Investigators will implement the manipulation of mental contrasting/implementation intentions, focusing on the couple. This will entail 3 steps that involve: 1) contrasting of positive future outcomes associated with present conditions that hinder achievement of positive future outcomes (i.e., barriers); 2) strategies to overcome barriers and hence facilitate weight loss; and 3) construction of implementation intentions.
Active Comparator: Individual Condition
Couples randomized to the individual condition will be stratified on gender and one partner, chosen at random, will undergo the experimental manipulations and complete all study surveys while the other will not (heretofore called the active partner vs. the passive partner). The active partner will receive BMI feedback based on measurements taken during the intervention appointment, complete three surveys, and verbally state some goals and plans for weight loss to the passive partner. The passive partner will not complete any study materials or participate in the intervention during the session.
Behavioral: Mental Contrasting- Individual
Investigators will implement the manipulation of mental contrasting/implementation intentions, focusing on the individual. This will entail 3 steps that involve: 1) contrasting of positive future outcomes associated with present conditions that hinder achievement of positive future outcomes (i.e., barriers); 2) strategies to overcome barriers and hence facilitate weight loss; and 3) construction of implementation intentions.
- weight loss [ Time Frame: one month ]Measure weight loss between baseline and one month visits
- dietary changes [ Time Frame: one month ]Look at dietary changes in self-report questionnaire.
- number of minutes of physical activity [ Time Frame: one month ]Measure minutes of physical activity through self-report questionnaire.
