NCT07355244

Brief Summary

This randomized controlled trial aims to evaluate the effect of a structured self-affirmation intervention on pain, depression, anxiety, and stress levels in patients undergoing mastectomy. The study will be conducted in two parallel groups, with the intervention group listening to an audio recording of positive self-affirmation statements. Primary outcomes will be assessed using the Visual Analog Scale and the Depression Anxiety Stress Scale (DASS-21). The goal is to provide evidence-based strategies to reduce psychosocial burden after mastectomy.

Outcome Measures

Primary Outcomes (2)

  • Pain intensity

    Measured using the Visual Analog Scale (VAS), scored from 0 (no pain) to 10 (worst pain).

    Baseline (preoperative, T0), postoperative day 1 (T1), postoperative day 3 (T2, before discharge), and day 10 follow-up (T3).

  • Depression, Anxiety, and Stress (DASS-21 subscales)

    Assessed using the DASS-21 (validated Turkish version), a 21-item instrument with three subscales (depression, anxiety, stress), Likert 0-3; reliability previously reported (Cronbach's α \~0.88 in this study)

    T0 (preoperative baseline), T1 (post-op day 1), T2 (post-op day 3, before discharge), T3 (post-op day 10 follow-up).

Secondary Outcomes (1)

  • Intervention adherence (daily listening frequency)

    From T0 training through T3 (daily tracking until day 10 post-op).

Study Arms (2)

Control Group (Standard Care)

NO INTERVENTION

Participants in the control arm will receive standard postoperative care according to hospital protocols. No additional behavioral or psychological intervention will be administered.

Intervention Group (Self-Affirmation Audio)

EXPERIMENTAL

Participants in the intervention arm will receive a behavioral intervention consisting of an audio recording of positive self-affirmation statements accompanied by calming background sounds (birds chirping and flowing water). The recording lasts approximately 5 minutes and 40 seconds and will be delivered via an MP3 player and headphones. Patients will be instructed to listen to the recording at least once daily during the postoperative period, with encouragement to listen more frequently if desired.

Behavioral: Positive Self-Affirmation Audio with Calming Background Sounds

Interventions

Participants in the intervention arm will receive a behavioral intervention consisting of an audio recording of positive self-affirmation statements accompanied by calming background sounds (birds chirping and flowing water). The recording lasts approximately 5 minutes and 40 seconds and will be delivered via an MP3 player and headphones. Patients will be instructed to listen to the recording at least once daily during the postoperative period, with encouragement to listen more frequently if desired.

Masking Details
This study is open-label. Masking was not feasible due to the nature of the behavioral intervention (audio recording of self-affirmation statements). Both participants and investigators were aware of group assignments.

Intervention Model
PARALLEL
Model Details: This study uses a parallel assignment model with two arms: an intervention group and a control group. Participants will be randomly assigned to groups using block randomization via a computer-based system (randomizer.org). The intervention group will receive a structured self-affirmation audio recording with calming background sounds, while the control group will receive standard care without additional intervention. The study is open-label, as masking is not feasible due to the nature of the behavioral intervention.
