To develop an Opioid Overdose Knowledge Scale (OOKS) and an Opioid Overdose Attitudes Scale (OOAS) to evaluate take-home naloxone training.
Psychometric instrument development study conducted in England using convenience samples. Forty-five items were selected for the OOKS organised in four sub-scales (risks, signs, actions and naloxone use). The OOAS was formed initially of 32 items grouped in three sub-scales (competence, concerns and readiness). Both scales were administered to 42 friends and family members of heroin users and 56 healthcare professionals to assess internal reliability and construct validity. The Brief Overdose Recognition and Response Assessment (BORRA) and the General Self-Efficacy Scale (GSE) were also administered to family members to test concurrent validity. Family members completed the OOKS and OOAS on a second occasion to assess test-retest reliability.
The OOKS and OOAS were internally reliable (Cronbach's alpha=0.83 and 0.90, respectively). Retest was completed by 33 participants after 14 (SD 7) days (OOKS, ICC=0.90 and OOAS, ICC=0.82) with sub-scale item sets from each measure falling within the fair-to-excellent range (ICC=0.53-0.92). Professionals reported significantly higher scores on both scales than family members. The OOKS total score was positively correlated with the BORRA's Overdose Recognition (r=0.5, P<0.01) and Naloxone Indication sub-scales (r=0.44, P<0.05), but the total score on the OOAS was not associated with the GSE (r=0.02, NS).
The 45-item OOKS and 28-item OOAS are suitable as outcome measures of take-home naloxone training for friends and family members of opioid users.
开发阿片类药物过量知识量表（OOKS）和阿片类药物过量态度量表（OOAS），以评估家庭用纳洛酮培训。
在英国使用便利样本进行心理计量学工具开发研究。选择 45 项 OOKS 项目，分为四个分量表（风险、体征、行动和纳洛酮使用）。OOAS 最初由 32 项组成，分为三个分量表（能力、关注和准备）。两个量表均用于 42 名海洛因使用者的朋友和家人以及 56 名医疗保健专业人员，以评估内部信度和结构效度。还向家庭成员施测简短的药物过量识别和反应评估（BORRA）和一般自我效能感量表（GSE），以检验同时效度。家庭成员在第二次测试中完成 OOKS 和 OOAS，以评估测试 - 重测信度。
OOKS 和 OOAS 的内部信度分别为 0.83 和 0.90（克朗巴赫 α）。在 14 天（SD=7）后，33 名参与者完成了重测（OOKS，ICC=0.90 和 OOAS，ICC=0.82），每个量表的子量表得分均处于良好至优秀范围内（ICC=0.53-0.92）。专业人员在两个量表上的得分均显著高于家庭成员。OOKS 总分与 BORRA 的药物过量识别（r=0.5，P<0.01）和纳洛酮指征子量表（r=0.44，P<0.05）呈正相关，但 OOAS 总分与 GSE 无关联（r=0.02，NS）。
45 项 OOKS 和 28 项 OOAS 适合作为阿片类药物使用者的朋友和家人家庭用纳洛酮培训的结果测量。
