ObjectiveChild and youth mental health problems are often assessed by parent self-completed checklists that produce dimensional scale scores. When converted to binary ratings of disorder, little is known about their psychometric properties in relation to classifications based on lay-administered structured diagnostic interviews. In addition to estimating agreement, our objective is to test for statistical equivalence in the test-retest reliability and construct validity of two instruments used to classify child emotional, behavioural, and attentional disorders: the 25-item, parent completed Ontario Child Health Study Emotional Behavioural Scales-Brief Version (OCHS-EBS-B) and the Mini International Neuropsychiatric Interview for Children and Adolescents-parent version (MINI-KID-P).MethodsThis study draws on independent samples (n = 452) and uses the confidence interval approach to test for statistical equivalence. Reliability is based on kappa (κ). Construct validity is based on standardized beta coefficients (β) estimated in structural equation models.ResultsThe average differences between the MINI-KID-P and OCHS-EBS-B in κ and β were −0.022 and −0.020, respectively. However, in both instances, criteria for statistical equivalence were met in only 5 of 12 comparisons. Based on κ, between-instrument agreement on the classifications of disorder went from 0.481 (attentional disorder) to 0.721 (emotional disorder) but were substantially higher (0.731 to 0.895, respectively) when corrected for attenuation due to measurement error.ConclusionsAlthough falling short of equivalence, the results suggest on balance that the reliability and validity of the two instruments for classifying child psychiatric disorder assessed by parents are highly comparable. This conclusion is supported by the high levels of agreement between the instruments after correcting for attenuation due to measurement error. 相似文献

[Purpose] “Katakori” refers to a nonspecific symptom, including discomfort or dull pain, that is experienced around the occiput and that extends through the cervical spine to the acromion and scapular area. This study aimed to develop a patient-reported outcome measure of disability due to Katakori, namely the Katakori Disability Index, via evaluating patient comprehensibility and comprehensiveness. [Participants and Methods] We conducted a semi-structured interview among participants who had experienced Katakori consistently during the past month to examine patient comprehensibility and comprehensiveness; we particularly used the thinking-aloud method and cognitive debriefing to evaluate comprehensibility. [Results] We initially tested a provisional version of the Katakori Disability Index with 24 items using two 11-point numeric rating scales in a subset of 10 participants. Considering the issues identified concerning comprehensibility and comprehensiveness, we created a second draft of the Katakori Disability Index with two 6-point Likert scales, modified items, and four additional items. The second draft was tested in another subset of 10 participants. We eventually developed a 31-item Katakori Disability Index with modified instructions and items, two additional items, and a post-survey checklist; all these features addressed the concerns identified and suggestions obtained in the second round of interviews. [Conclusion] We developed a 31-item Katakori Disability Index with content validity. 相似文献

护士胜任特征的概念和成分分析 总被引:4,自引:0,他引:4
目的: 界定护士胜任特征的概念和成分,进而为选拔和培训出未来业绩优秀护士. 方法: 运用技术性文献分析、开放性译码、主轴译码等质性理论研究方法,结合问卷调查和相关分析等量性研究手段,以及行为事件访谈技术对护士胜任特征概念和成分进行了研究. 结果: ①护士胜任特征是以心理条件为基础的,受护士职业环境的影响,通过个体对外在事物的内化,在护士职业活动中表现出来的具有区别绩效优秀与一般护士的潜在的、发展的、持久的综合特征,包含有3个维度,16个成分. ②优秀组与普通组在访谈字数的长度上无明显差异(P>0.05),大多数胜任特征编码的频次与访谈长度不相关,说明编码指标采用胜任特征频数分析有较好稳定性,胜任特征归类一致性系数为80.05%,说明胜任特征评价法的编码者一致性相当高,所用的胜任特征编码程序的客观性、操作性是较高的. 结论: 培养优秀护士应将能力培养、品格塑造、心理动力激发以及行为表现的引导统一起来全面实施. 相似文献

BackgroundThe patient–clinician interaction is a site at which defensive practice could occur, when clinicians provide tests, procedures and treatments mainly to reduce perceived legal risks, rather than to advance patient care. Defensive practice is a driver of low‐value care and exposes patients to the risks of unnecessary interventions. To date, patient perspectives on defensive practice and its impacts on them are largely missing from the literature. This exploratory study conducted in Australia aimed to examine the views and experiences of healthcare consumer representatives in this under‐examined area.MethodsSemi‐structured interviews were conducted with healthcare consumer representatives involved in healthcare consumer advocacy organisations in Australia. Data were transcribed and analysed thematically.ResultsNine healthcare consumer representatives participated. Most had over 20 years of involvement and advocacy in healthcare, including personal experiences as a patient or carer and/or formal service roles on committees or complaint bodies for healthcare organisations. Participants uniformly viewed defensive practice as having a negative impact on the clinician–patient relationship. Themes identified the importance of fostering patient–clinician partnership, effective communication and informed decision‐making. The themes support a shift from the concept of defensive practice to preventive practice in partnership, which focuses on the shared interests of patients and clinicians in achieving safe and high‐value care.ConclusionThis Australian study offers healthcare consumers'' perspectives on the impacts of defensive practice on patients. The findings highlight the features of clinician–patient partnership that will help to improve communication and decision‐making, and prevent the defensive provision of low‐value care.Patient or Public ContributionHealthcare consumer representatives were involved as participants in this study. 相似文献
