The Effect of Transtheoretical Model-Based Motivational Interviewing on Postpartum Contraception

The goal of this clinical trial is to evaluate the effect of transtheoretical model-based antenatal and postnatal motivational interviewing on contraceptive self-efficacy, contraceptive attitude, and postpartum contraception use. This study was planned as a single-centre, parallel-group, randomized controlled trial design. The study group consisted of 72 women at 28-32 weeks of gestation (intervention group n=36, control group n=36). Block randomization stratified by parity will be used to assign participants to groups. The intervention group will receive antenatal and postnatal motivational interviewing in addition to routine care, while the control group will receive routine care only. Outcomes will be evaluated at 12 weeks postpartum. Data will be collected using a personal information form, Contraceptive Self-Efficacy Scale, Contraceptive Attitude Questionnaire, Contraceptive Use Form and Stages of Behavior Change Short Form.

About this study

Short gestational intervals are known to be directly associated with adverse pregnancy outcomes, such as gestational diabetes, maternal obesity, anemia, maternal mortality, severe maternal morbidity, preterm delivery, low birth weight, and infant mortality. The most important step in establishing optimum pregnancy intervals can be achieved by meeting the contraceptive needs of postpartum women. Motivational interviewing incorporates components of contraception counseling best practices, such as building trust, optimizing the decision-making process, improving self-efficacy, and protecting the autonomy of the individual, which allows it to be actively used in the counseling process. Therefore, this study aimed to investigate the effects of transtheoretical model-based motivational interviewing on postpartum contraception. In this study, the intervention group will receive two motivational counseling sessions in the antenatal period and one motivational interviewing session in the postnatal period in addition to routine care, while the control group will receive only routine care. The data will be coded as A and B in SPSS (Statistical Package for the Social Sciences) and analyzed by an independent statistical expert.

Treatment and study plan

Motivational interviewing group

Behavioral

The intervention group will receive motivational interviewing based on the transtheoretical model in addition to routine care. Motivational interviews are structured in line with the stages of change and behavioral change processes, which are the basic structures of the transtheoretical model. Three sessions of motivational interviewing with a session duration of 30 min will be implemented. Two sessions of motivational interviewing in the prenatal period and one session of motivational interviewing in the postnatal period.

Other names: Transtheoretical model-based motivational interviewing group

Control Group

Other

Participants in the control group will receive routine care at the center.

Primary outcomes

  1. Postpartum contraceptive method use questionnaire

    Time frame: 12 weeks postpartum

    The questionnaire assesses the contraceptive method used by the participants in the postpartum period. It consist of questions assessing the contraceptive method used by the participants and the time of onset. The number of participants using modern contraceptive methods in the postpartum period has been reported.

  2. Contraceptive Attitude Questionnaire

    Time frame: At baseline and 12 weeks postpartum

    It was developed to assess contraceptive attitude. Contraceptive attitude questionnaire consists of three sub-dimensions ; effects on family economy and sexual life, effects on moral values of the society, effects on men and religion. The higher the score, the higher the contraceptive attitude.

  3. Contraceptive Self Efficacy Scale

    Time frame: At baseline and 12 weeks postpartum

    Women's contraceptive self-efficacy will be assessed using the Turkish version of the Contraceptive Self-Efficacy Scale. The scale consists of 11 items and three sub-dimensions; (1) husband/partner communication, (2) provider communication, (3) choosing and managing a method. The total score ranged from 0 to 110. Higher scores indicate higher levels of contraceptive self-efficacy.

Secondary outcomes

  1. Stages of Behavior Change

    Time frame: At baseline and 12 weeks postpartum

    The transtheoretical model (stages of change model), which is widely used to determine the process of behavior change, was adapted to postpartum contraception behavior. This form will be used to assess participants' stages of behavior change (precontemplation, contemplation, preparation, action, maintenance) regarding contraceptive use.

  2. Consistent use of contraceptive methods

    Time frame: 12 weeks postpartum

    The questionnaire evaluates the consistent use of contraceptive methods by participants in the postpartum period. It consists of questions evaluating consistent use according to the type of contraceptive method.

  3. Contraceptive method satisfaction

    Time frame: 12 weeks postpartum

    The satisfaction level of participants using modern contraceptive methods is evaluated.
