An implementation intentions intervention to increase uptake of mammography

Area of Science:

• Health behavior research
• Public health interventions
• Psychology of decision-making

Background:

• Breast cancer screening uptake is crucial for early detection.
• The National Health Service Breast Screening Programme in the UK aims to improve attendance rates.
• Implementation intentions interventions offer a potential strategy to enhance screening participation.

Purpose of the Study:

• To evaluate an implementation intentions intervention designed to increase attendance at NHS Breast Screening Programme appointments.
• To assess the effectiveness of planning to overcome specific barriers to screening attendance.

Main Methods:

• A randomized controlled trial involving 2,082 participants allocated to intervention, assessment-only, or nonassessment control groups.
• The intervention group developed plans to address barriers such as changing appointments, arranging transport, and negotiating time off work.
• Control groups were used to isolate the effects of the questionnaire and research team contact.

Main Results:

• Overall attendance rates were similar across all three groups (around 80%).
• However, within the intervention group, women who actively planned to take time off work were significantly more likely to attend screening.
• Strong intentions coupled with perceived low control over arrangements were associated with higher likelihood of planning.

Conclusions:

• The study highlights the critical role of planning within implementation intentions interventions for health behaviors.
• Findings support the theoretical distinction between motivation (intentions) and volition (planning and execution).
• Tailoring interventions to address specific barriers and individual perceptions of control may enhance effectiveness.
