About this study

This study will investigate three interventions-values clarification, planning, or combined (values clarification + planning)-for increasing goal-consistent health behavior (e.g., exercise or dieting). The investigators will also examine how intervention effects differ based on various psychological and neuropsychological factors, to better understand how interventions can be tailored to specific individuals.

The investigators hypothesize a) that the combined intervention will increase goal-consistent exercise behavior more than the other interventions; and b) that individuals scoring higher on self-concordance or goal-commitment will benefit more from planning, whereas those with more positive expectancies or scoring higher on neuropsychological measures (e.g., working memory) will benefit more from values clarification.

Read the detailed description

The study will be a repeated measures design examining the between-subjects effect of intervention condition (values clarification, planning, and combined) on self-reported health goal progress and related outcomes at 1-week and 4-week follow-up, relative to baseline. Based on this design, participants will first be instructed to generate a health-related goal on which they want to make progress over the course of the next month (following procedures adapted from Little, 1993, and Sheldon \& Kasser, 1998; see details below). Participants will then be randomly assigned (using a random number table) to one of three intervention conditions: (1) values clarification, (2) planning, and (3) combined (values clarification + planning). All conditions are described in more detail below. Fifty-three participants will be randomized to each condition. Questionnaire measures assessing a variety of psychological variables as well as neuropsychological measures will be modeled as between-subject predictor and/or moderator variables of goal-consistent health behavior. Additionally, differences in self-concordance, goal commitment, and expectancies of success will be modeled as potential moderator and/or mediator variables.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Values ClarificationBehavioural

    This intervention will incorporate elements from several widely established self-regulatory strategies aimed at enhancing the motivational aspects of goal pursuit, including mental contrasting (Oettingen, 2000), self-reflection (Koestner et al., 2002), self-affirmation (Schmeichel and Vohs, 2009), and the values clarification components of Acceptance and Commitment Therapy (ACT; Hayes, Strosahl, \& Wilson, 1999). Participants will be prompted to enter their selected health goal and will then be instructed to identify personal values that might be practiced in pursuit of this goal. Participants will write about these values for several minutes, after which they will be instructed to select a short phrase or image that conjures up for them the reasons they choose to engage in their goal. Participants will be asked to type the phrase into a textbox and will have the option of receiving a confidential print-out of their chosen phrase at the end of the study visit.

  • PlanningBehavioural

    Participants in this condition will be guided to create detailed implementation intentions, or if-then planning statements (Gollwitzer \& Sheeran, 2006), specifying when, how, and where they will engage in their selected health goal. Participants will be provided with a detailed rationale adapted from earlier research on implementation intentions (e.g., Webb et al., 2010). Participants will be guided to generate a plan indicating when, where, and how they will enact their goal-based behavior over the next week. They will also be prompted to identify 3 obstacles they are likely to encounter during the pursuit of each goal, and to specify in an "if-then" format what specific actions they will take to overcome each obstacle (following the procedures and sample "if-then" responses of Koestner et al., 2002). They will be asked to rehearse each "if-then" statement to themselves before the end of the visit.

  • CombinedBehavioural

    Participants in this condition will complete abbreviated versions of both the "values clarification" and "planning" procedures, as detailed above. Participants will be prompted to identify 2 obstacles (as opposed to 3) they might encounter during the pursuit of each goal. For each of the obstacles they identify with respect to each of their target goals, they will be prompted to form an additional implementation intention in the form: "When [I encounter the specified obstacle], I will do [X] and remember [values-based statement or image identified during "values clarification" exercise]. They will be asked to rehearse these "if-then" statements to themselves before the end of the visit.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Goal Progress

    This 3-item goal progress measure assesses participants' self-reported effort towards and success at meeting their specified goal over the past week, each on a 7-point Likert scale. The third item assesses the number of actions participants have undertaken to realize their goal in the past week (previously shown to be a valid indicator of goal pursuit; Oettingen et al., 2001; Sevincer \& Oettingen, 2009).

    Measured: Change from baseline to 1-week and 4-week follow-ups

Secondary outcomes (17)
  1. Perceived Locus of Causality (PLOC)

    The PLOC scale (Sheldon \& Kasser, 1995, 1998) is a 4-item measure of the level of autonomy or self-concordance that participants experience with respect to a given goal.

    Measured: Change from baseline to 1-week and 4-week follow-ups

  2. Positive and Negative Affect Schedule (PANAS)

    Participants rate 20 adjectives describing positive and negative affect states on a 5-point Likert scale indicating to what extent they currently feel that way.

    Measured: Change from baseline to 1-week and 4-week follow-ups

  3. Goal Rating Measure

    On a 7-point Likert scale, participants will rate their health-related goal regarding their expectancies of success, their energization towards the goal, and the perceived difficult and importance of the goal.

    Measured: Change from baseline to 1-week and 4-week follow-ups

  4. Goal Orientation Scale

    This is a 5-item scale that assesses participant's orientation toward a growth/learning-focused versus fixed/performance-focused motivation, adapted from Brett and VandeWalle (1999).

  10. Need for Cognition Scale (Short Form)

    The NCS-SF (Cacioppo, Petty, \& Kao, 1984) is an 18-item scale that assesses the characteristic tendency to enjoy and seek out cognitively challenging tasks and activities.

    Measured: Change from baseline to 1-week and 4-week follow-ups

  11. Cognitive Reflection Test (CRT)

    The CRT (Frederick, 2005) is a 3-item task that assesses the tendency to use "fast," intuitive heuristic-based reasoning versus "slow," more deliberative reasoning

    Measured: Change from baseline to 1-week and 4-week follow-ups

  12. Implicit Attitudes toward Effort

    The investigators will use an adapted version of the Brief Implicit Association Test (B-IAT; Sriram \& Greenwald, 1998) to assess participants' implicit tendency to appraise the experience of effort as either "good" or "bad."
