This study examined the impact of motivational interviewing (MI) counseling time on self-efficacy to practice safer sex for people living with HIV/AIDS (PLWHA).
In 4 month intervals we followed a cohort of 490 PLWHA for 12 months. We conducted hierarchical linear regression models to examine changes in safer sex self-efficacy when participants received zero, low to moderate (5-131 min) and high (132-320 min) doses of MI time. We conducted a similar analysis using number of counseling sessions as the predictor variable.
Participants with low to moderate doses of MI counseling had 0.26 higher self-efficacy scores than participants with zero MI time (p=0.01). Also, they had 0.26 lower self-efficacy scores than participants with high amounts of MI time (p=0.04). Participants with high doses of MI had a 0.5 higher self-efficacy score than participants with zero amount of MI time (p<0.0001). Participants who received 3-4 counseling sessions had 0.41 greater self-efficacy scores than participants who did not receive any sessions (p<0.0001) but did not differ from participants receiving 1-2 sessions.
MI time is a key to enhancing safer sex self-efficacy among PLWHA.
Safer sex self-efficacy improves the more MI counseling time and sessions PLWHA receive.
本研究考察了动机性访谈（MI）咨询时间对艾滋病毒/艾滋病（PLWHA）患者实践安全性行为的自我效能的影响。
我们以 4 个月为间隔，对 490 名 PLWHA 进行了 12 个月的随访。我们进行了层次线性回归模型分析，当参与者接受零剂量、低至中等剂量（5-131 分钟）和高剂量（132-320 分钟）的 MI 时间时，观察安全性行为自我效能的变化。我们使用咨询次数作为预测变量进行了类似的分析。
接受低至中等剂量 MI 咨询的参与者的自我效能评分比接受零剂量 MI 时间的参与者高 0.26（p=0.01）。此外，他们的自我效能评分比接受高剂量 MI 时间的参与者低 0.26（p=0.04）。接受高剂量 MI 的参与者的自我效能评分比接受零剂量 MI 时间的参与者高 0.5（p<0.0001）。接受 3-4 次咨询的参与者的自我效能评分比未接受任何咨询的参与者高 0.41（p<0.0001），但与接受 1-2 次咨询的参与者没有差异。
MI 时间是提高 PLWHA 安全性行为自我效能的关键。
PLWHA 接受的 MI 咨询时间和次数越多，安全性行为自我效能就越高。
