Understanding contraceptive effectiveness is key for informed choices. Audiovisual aids and categorized data improve knowledge and method selection compared to standard presentations.

Area of Science:

  • Reproductive Health
  • Evidence-Based Medicine
  • Health Communication

Background:

  • Informed contraceptive choice necessitates understanding method effectiveness, including pros, cons, and pregnancy likelihood.
  • Consumer comprehension of contraceptive risks and benefits influences method selection and adherence.

Purpose of the Study:

  • To systematically review randomized controlled trials (RCTs) evaluating strategies for communicating contraceptive effectiveness to consumers.
  • To identify effective communication methods that enhance understanding and inform contraceptive choices.

Main Methods:

  • Comprehensive literature search across multiple databases (MEDLINE, POPLINE, CENTRAL, PsycINFO, EMBASE) and reference lists.
  • Inclusion of RCTs comparing different communication strategies for contraceptive effectiveness.

  • Data extraction and analysis using RevMan, calculating odds ratios (OR) and weighted mean differences (WMD) with confidence intervals (CI).

    • Main Results:

    • Audiovisual presentations improved knowledge gain compared to oral physician presentations (WMD -19.00; 95% CI -27.52 to -10.48).
    • Effectiveness presented in categories, with or without numbers, led to more correct answers than number-based tables alone (ORs ranging from 2.03 to 2.58).
    • An expanded communication program increased likelihood of choosing sterilization (OR 4.26; 95% CI 2.46 to 7.37) or modern contraceptive methods (OR 2.35; 95% CI 1.82 to 3.03).

    Conclusions:

    • Limited evidence exists on optimal strategies for communicating contraceptive effectiveness to consumers.
    • Categorical presentation of pregnancy risk data and audiovisual aids appear more effective than numerical data and standard oral presentations.
    • Further research in clinical settings is needed to assess the impact of communication strategies on contraceptive choice and knowledge retention, ideally utilizing theoretical frameworks.
