Effectiveness of Volitional Help Sheets as an Adjunct to Treatment to Promote Behavior Change: A Pilot Study on Smoking (VHS_T)

Effectiveness of Volitional Help Sheets as an Adjunct to Treatment to Promote Behavior Change: A Pilot Study on Smoking (VHS_T)

Smoking is a major public health concern associated with substantial morbidity and premature mortality. Planning may help people who wish to change their smoking behavior by translating their intentions into action.

Volitional help sheets (VHS) are brief, low-cost tools designed to support behavior change. They help individuals create personalized "if-then" plans by linking situations in which they may be tempted to smoke with strategies for responding to those situations.

Previous studies suggest that VHS may support changes in smoking and other health behaviors. However, they have mainly been evaluated in English-speaking populations, outside clinical settings, and as stand-alone interventions.

This pilot study aims to evaluate the effectiveness of a smoking-specific volitional help sheet as an adjunct to care in a clinical setting.

Description détaillée

Smoking is a major public health concern. For people who wish to change their smoking behavior, planning strategies may help translate intentions into action. Volitional help sheets (VHS) are brief tools that support this process by helping individuals create personalized "if-then" plans. These plans link situations in which a person may be tempted to smoke with strategies for responding to those situations.

Previous studies suggest that VHS may support changes in smoking and other health behaviors. However, they have mainly been evaluated in English-speaking populations, outside clinical settings, and as stand-alone interventions. This pilot study will evaluate a smoking-specific VHS as an adjunct to usual care in a clinical setting.

This is a single-center, randomized, controlled, single-blind interventional study conducted in the tobacco treatment department of the Clinique de la Mitterie. Patients will be invited to participate after their first tobacco treatment consultation. Eligible patients who provide informed consent will complete baseline assessments and be assigned to one of two groups:

  • VHS group: participants will receive usual tobacco treatment care and complete a volitional help sheet. They will select situations and strategies relevant to their personal smoking-related goal and link them to form "if-then" plans.
  • Control group: participants will receive usual tobacco treatment care. Usual care is tailored to each patient's needs and goals. It may include individual consultations or participation in a day-hospital program addressing topics such as tobacco use and emotions, motivation for change, and well-being.

Data will be analyzed using a sequential Bayesian approach. Recruitment may stop when the prespecified threshold for evidence in favor of an effect or no effect is reached, or when the maximum planned sample size is reached. The planned recruitment period is up to 60 months, and each participant will be followed for approximately one month

Groupe de participants / Bras
Intervention / Traitement
Aucune intervention: Usual care

Participants will receive usual tobacco treatment care according to their individual needs and goals. They will not complete the volitional help sheet.

Expérimental: Volitional Help Sheet plus Usual Care

Participants will receive usual tobacco treatment care and complete a smoking-specific volitional help sheet after their first tobacco treatment consultation. They will select personally relevant situations in which they may be tempted to smoke and strategies to respond to those situations, then link them to form "if-then" plans.

Que mesure l'étude ?

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Change in cigarette dependence as measured by the Cigarette Dependence Scale (CDS-12)
Délai: Baseline and one month after the intervention

Change in cigarette dependence between baseline and the one-month follow-up, assessed using the 12-item Cigarette Dependence Scale (CDS-12). Changes will be compared between the volitional help sheet plus usual care group and the usual care alone group.

Total scores range from 12 to 60, with higher scores indicating greater cigarette dependence and a worse outcome.

Baseline and one month after the intervention

Mesures de résultats secondaires

Mesure des résultats
Description de la mesure
Délai
Change in smoking behavioral automaticity
Délai: Baseline and one month after the intervention

Change in the subjective automaticity of smoking behavior between baseline and the one-month follow-up, assessed using the Self-Report Behavioral Automaticity Index (SRBAI).

Mean scores range from 1 to 7, with higher scores indicating greater automaticity of smoking behavior and a worse outcome.

Baseline and one month after the intervention
Change in smoking-related behavioral identity
Délai: Baseline and one month after the intervention

Change in smoking-related behavioral identity between baseline and the one-month follow-up, assessed using the Self-Report Behavioral Identity Index (SRBII).

The questionnaire comprises four items rated from 1 to 7. The overall score is calculated as the mean of the four items and ranges from 1 to 7, with higher scores indicating stronger identification with smoking behavior and a worse outcome. A decrease in score indicates improvement. Changes will be compared between the volitional help sheet plus usual care group and the usual care alone group.
