Volitional help sheets use Gollwitzer's (1993) concept of implementation intentions as a vehicle to change behaviour using Prochaska and DiClemente's (1983) processes of change. The present study designed and tested a volitional help sheet to increase physical activity in a group with low socioeconomic status (low-SES). Sixty-eight people (33 women, 35 men;(More)
AIMS This study tested the ability of a volitional help sheet (VHS) to decrease binge drinking in UK students. METHODS Fifty-six participants were randomly allocated to one of three conditions: control, active control or VHS as part of a questionnaire-based study. RESULTS There were significant decreases in units of alcohol consumed and self-reported(More)
A. Weller and L. Weller (1997) claimed to report "the definitive study of menstrual synchrony" (p. 148). To allow for cycle variability, they used the following criterion for synchrony: It occurred in 2 out of 3 months. The underlying assumption of the state of menstrual synchrony is that cycle length variability is minimal. The present article uses a(More)
OBJECTIVE To test the ability of a new, brief means of affirming the self (the "self-affirming implementation intention") to decrease alcohol consumption against a standard means of self-affirmation (the self-affirming "kindness" questionnaire) and an active control condition; to test whether self-affirmation effects can be sustained beyond the experimental(More)
This study tested discontinuity patterns across the stages of change. Fat intake, theory of planned behaviour (TPB) variables, and felt and potential ambivalence were assessed in 16-17 year olds (N = 187). Across the stages of change there were: (a) linear increases in TPB variables, (b) linear decreases in fat intake, and (c) quadratic relationships with(More)
BACKGROUND Twenty percent of pregnant women in the UK are obese (BMI ≥ 30 kg/m2), reflecting the growing public health challenge of obesity in the 21st century. Obesity increases the risk of adverse outcomes during pregnancy and birth and has significant cost implications for maternity services. Gestational weight management strategies are a high priority;(More)
Relatively little research has examined factors that account for transitions between transtheoretical model (TTM) stages of change. The present study (N = 787) used sociodemographic, TTM, and theory of planned behavior (TPB) variables, as well as theory-driven interventions to predict changes in stage. Longitudinal analyses revealed that sociodemographic,(More)
Volitional help sheets (VHS) have been shown to be effective in changing health behavior, but not yet alcohol consumption in a general population. The aim of the present research was to test the ability of VHS to reduce alcohol consumption against an active control condition, a "standard" self-generated implementation intention condition, and forming a(More)
OBJECTIVE Alcohol consumption in adolescence is associated with problem drinking in later life, and there is a need to develop evidence-based interventions to reduce adolescent alcohol consumption. The aims of the present study were to test the ability of a very brief intervention based on self-affirmation theory to reduce alcohol consumption in a sample of(More)
OBJECTIVE To see whether the stages of change are useful for targeting a brief intervention to reduce smoking based on implementation intentions. A second objective was to rule out demand characteristics as an alternative explanation for the findings of intervention studies based on the transtheoretical model and implementation intentions.
