Applying the Transtheoretical Model to Regular Moderate Exercise in an Overweight Population: Validation of a Stages of Change Measure

Transtheoretical Model-based multiple behavior intervention for weight management: Effectiveness on a population basis

“…Stage of Change for Exercise-This reliable and valid measure (Sarkin et al, 2001) assessed readiness to engage in moderate exercise at least 30 minutes per day 5-7 days per week. The Godin Leisure-Time Exercise Questionnaire (GLTEQ: (Godin & Shepard, 1985) varied significantly by stage F(3,846) = 79.43, p < .001.…”

Validating stage of change measures for physical activity and dietary behaviors for overweight women

“…[18][19][20][21] One study reported using psychosocial constructs (for example, self-efficacy, decisional balance) hypothesized to be related to the stages of change to test concurrent validity for moderate PA in overweight adults. 22 The present study investigated the validity of four staging measures in a target population of overweight and obese women enrolled in a weight loss intervention program. The staging measures included four algorithms assessing readiness to change PA, and intakes of fruit and vegetables (FVs), dietary fiber (FB) and DF.…”

Effect of School-based Wellness Intervention in 7th Graders on Stage of Change for Lifestyle Behaviors: The MATCH Program

“…This assumption has been supported by several published studies [23,26,27] and served as the rationale for this study design aimed at determining the validity of the SOC survey question in assessing readiness to change dietary and PA behaviors. Therefore, the purpose of this study in young adolescents participating in the MATCH intervention is three-fold; to determine 1) the validity of the single-item SOC survey question, 2) if MATCH participation was associated with a change in SOC, and 3) associations with baseline and changes in SOC and changes in BMI z-score.…”

“…However, the incorporation of lengthy, complex algorithms that measure SOC for just a few behaviors into established questionnaires is not always feasible due to time and length constraints. In adults regarding staging for PA, a few studies have demonstrated promising results that a single-item format with 5-choice responses, each choice representing a SOC, has been effective [25,26]. The lack of consensus for measuring SOC for PA and dietary behaviors in adolescents underscores the need to examine the validity of a single-item SOC measure that identifies intentions towards becoming more physically active and eating healthier.…”
