Motivational interviewing (MI) increasingly is used in behavior change counseling. We explored whether commitment verbalized in an initial MI session predicted subsequent physical activity behavior.
As part of a 12-week walking program targeted at rural women, an initial MI session was held that was audio-recorded. We measured commitment strength during this MI session, stage of change (SOC) pre- and postintervention, and minutes of physical activity performed during the 12-week intervention for the 20 women in the intervention.
Commitment strength was significantly correlated with SOC, and SOC was significantly correlated with physical activity behavior. However, commitment strength did not predict physical activity. Further research is needed to determine if commitment strength predicts subsequent physical activity.
Understanding the role of the strength of a commitment statement made during an initial MI session could assist the APN in directing follow-up MI sessions. This information could be useful in improving the cost effectiveness and efficiency of conducting MI.
动机性访谈（MI）在行为改变咨询中的应用日益广泛。我们探讨了在初次MI访谈中表达的承诺是否能预测随后的身体活动行为。
作为一项针对农村女性的为期12周的步行计划的一部分，举行了一次初次MI访谈并进行了录音。我们在这次MI访谈中测量了承诺强度、干预前后的改变阶段（SOC），以及干预组中20名女性在12周干预期间进行身体活动的分钟数。
承诺强度与SOC显著相关，SOC与身体活动行为显著相关。然而，承诺强度并不能预测身体活动。需要进一步研究以确定承诺强度是否能预测随后的身体活动。
了解初次MI访谈中做出的承诺声明强度的作用，有助于高级实践护士指导后续的MI访谈。这些信息可能有助于提高进行MI的成本效益和效率。
