Development and Psychometric validation of the Diabetes Therapy-Related QOL (DTR-QOL) Questionnaire

Abstract

Objective:

We developed and evaluated the psychometric properties of the Diabetes Therapy-Related QOL (DTR-QOL) as a disease-specific, self-administered questionnaire to assess the influence of diabetes treatment on patient QOL, regardless of treatment method.

Methods:

This new questionnaire was developed and validated in a standardized manner: Item development, pilot-testing and psychometric validation. A survey was conducted using the provisional version of the questionnaire, and reliability and validity were evaluated with psychometric testing.

Results:

The provisional version of the questionnaire was generated with 29 items through literature review and pilot testing. For psychometric assessment, analyses were performed on the responses of 284 adult Japanese patients with diabetes. Factor analysis by the principal factor method with promax rotation revealed 4 factors; “burden on social activities and daily activities” (13 items), “anxiety and dissatisfaction with treatment” (8 items), “hypoglycemia” (4 items), and “satisfaction with treatment” (4 items). For reliability, the intraclass correlation was 0.92, and Cronbach’s alpha coefficient was 0.94, indicating adequate test-retest reliability and internal consistency. For known-group validity, there were significant differences in scores for following variables: age, diabetes type, HbA1c, treatment method, glycemic control, hypoglycemia, nocturnal hypoglycemia, concern about weight gain, health status (patient assessment), and degree of communication with physician.

Conclusions:

The DTR-QOL, with good reliability and validity, can assess the influence of diabetes treatment on patient QOL. The DTR-QOL can be used regardless of treatment method that patients receive, and this characteristic enables to detect a difference on patients QOL between treatment methods before and after a switch of treatment. Limitations of this study include representativeness of the patient sample. The relatively small number of patients with type 1 diabetes should be noted. Also, responsiveness of the DTR-QOL has not yet been examined.     

劳动合同对于进城务工人员收入影响的有效性分析

本文重点讨论了《劳动合同法》的颁布对于进城务工人员收入的影响,我们用博弈论模型证明了签订劳动合同可以提高务工人员的收入,并且在一定条件下企业也可以通过生产率的上升而获利,实现双赢。从统计上看,签订合同的工人月收入高出347.19元,小时收入高出2.16元,OLS回归结果也发现合同对于收入有显著的正影响。但同时我们注意到有合同的劳动者本身有着更好的素质,Probit和Logit模型都验证了这一点,基于这种可能的内生性偏误,我们使用了处置效应来控制这一问题,并发现签订合同依旧显著提高了收入,估计月收入提高14.0%—14.9%,小时收入提高18.2%—21.5%。     

Minimax regret treatment choice with covariates or with limited validity of experiments

This paper continues the investigation of minimax regret treatment choice initiated by Manski (2004). Consider a decision maker who must assign treatment to future subjects after observing outcomes experienced in a sample. A certain scoring rule is known to achieve minimax regret in simple versions of this decision problem. I investigate its sensitivity to perturbations of the decision environment in realistic directions. They are as follows. (i) Treatment outcomes may be influenced by a covariate whose effect on outcome distributions is bounded (in one of numerous probability metrics). This is interesting because introduction of a covariate with unrestricted effects leads to a pathological result. (ii) The experiment may have limited validity because of selective noncompliance or because the sampling universe is a potentially selective subset of the treatment population. Thus, even large samples may generate misleading signals. These problems are formalized via a “bounds” approach that turns the problem into one of partial identification.In both scenarios, small but positive perturbations leave the minimax regret decision rule unchanged. Thus, minimax regret analysis is not knife-edge-dependent on ignoring certain aspects of realistic decision problems. Indeed, it recommends to entirely disregard covariates whose effect is believed to be positive but small, as well as small enough amounts of missing data or selective attrition. All findings are finite sample results derived by game theoretic analysis.     

A comparative institutional analysis of agreements on product standards

The WTO and the EU have chosen two different agreements on product standards. While the WTO's approach is primarily based on a “National Treatment” (NT) principle, the EU's approach crucially relies on a principle of “Mutual Recognition” (MR). This paper offers a first look at the comparative performance of these two principles. We show that standards are imposed for levels of externalities that are too low under NT and too high under MR. This suggests that NT should be preferred to MR when the amount of trade in goods characterized by high levels of externalities is large.     

非互惠的零关税待遇是否促进了受惠国的出口多样化——基于中美对非洲贸易政策的比较研究

非互惠的优惠贸易待遇是世界贸易组织和国际社会支持发展中国家尤其是最不发达国家发展的重要工具。为了评估该政策的效果,本文以中美对非洲实施的零关税待遇为例,采用2001—2017年HS8位贸易数据从整体、行业和区域层面评估了两种政策对受惠国出口多样化产生的影响。结果显示,美国零关税待遇分为AGOA-GSP和AGOA-服装两个条款,中国零关税待遇(FOCAC)在遵循WTO规则、受惠商品范围、受惠国家标准、原产地标准及政策有效期方面均优于AGOA-GSP,但在原产地标准灵活度和政策优惠力度方面低于AGOA-服装。这些特征导致三类政策对受惠国出口多样化的影响产生显著的差异。整体上,FOCAC和AGOA-服装对受惠国出口多样化均产生了显著的积极影响,而AGOA-GSP的影响不显著;行业层面,FOCAC对受惠国制造业、矿业和农业的出口多样化均产生了显著的促进作用,而AGOA的两个条款对受惠国三个细分行业出口多样化的影响均不显著;区域层面,三类政策对受惠国出口多样化的影响仅在部分区域发挥效果。     

区域贸易优惠与最惠国待遇关系的冲突与法律协调——兼论我国之应对措施

区域贸易合作与多边贸易体制虽具有互补性,但彼此不能相互替代;区域贸易优惠与多边最惠国待遇实质上存在冲突,但它作为一项特殊例外存续于世贸组织体制之内。世贸组织规则确立了区域贸易优惠的合法性,从而为区域贸易提供了前所未有的发展机遇。分析区域贸易合作与多边贸易体制的关系、区域贸易优惠与世贸组织最惠国待遇的冲突,以及世贸组织规则对两者间关系的协调,有助于了解区域一体化发展进程,及时采取积极的应对措施。
