Comparability of data across modes is an important issue in survey research. In this paper we discuss item non-response to attitudinal questions in telephone and web surveys. We present results from a survey experiment conducted in Italy and in Spain that compares different presentations of response options in an online setting with a benchmark telephone survey. In line with earlier studies we find that (A), the share of non substantial answers in the online survey depends on how the response option is presented. Comparing different presentations in an online survey to the standard approach of telephone surveys using propensity score matching, we find that (B), the share and pattern of non substantial answers, is most similar across the two modes in the online survey when the it is captured in an instruction on each screen for the online survey. Our findings are of particular relevance for the design of multiple mode or mix-mode surveys of attitudinal questions using online and telephone modes. 相似文献

Studies of state repression of protest have focused on theories of threat and weakness, in which states repress movements that threaten state authority or elite interest or movements that lack organizational or political strength. Empirical studies have most often used regression analysis of protest-event datasets. This paper proposes qualitative comparative analysis (QCA) as an alternative approach to protest-event data that retains more qualitative complexity and captures the conjunctural and heterogeneous nature of causation during events. The paper applies both methods to protest data from the United States (1963–1973). While both methods provide strong evidence for the threat and weakness hypotheses, QCA more effectively illustrates how combinations of threat and weakness factors increase the risk of repression. The paper argues that QCA is a viable alternative approach to event data, but it should also be seen as a valuable complementary method that can improve regression-based approaches. 相似文献

Purpose: To test the psychometric properties of the International Prostate Symptom Score (Hong Kong Chinese version 2) (IPSS) in Chinese male patients with benign prostatic hyperplasia (BPH) under secondary care.Methods: A prospective longitudinal study was done by interviewing subjects at baseline, at 2 week after baseline for assessing test–retest reliability and at 26 week after baseline for assessing responsiveness. All subjects were interviewed to complete a structured questionnaire including IPSS, Short Form-12 Health Survey version 2 (SF-12v2) and Depression Anxiety Stress Scale (DASS).Results: The IPSS HRQOL score had weak correlations with SF-12v2 summary and DASS domain scores. For reliability analysis, Cronbach’s alpha coefficient was 0.90 for the seven symptom-related items. The intraclass correlation coefficients of the IPSS total symptom score and HRQOL score were 0.90 and 0.86, respectively. For sensitivity, statistically significant differences were detected between the subjects with BPH and those without for IPSS total symptom score (effect size?=?0.68) but not the IPSS HRQOL score. The areas under ROC curves for the IPSS total symptom and HRQOL scores were 0.67 and 0.60, respectively.Conclusions: The IPSS was valid, reliable instrument in Chinese patients with BPH. The IPSS total symptom score, but not the HRQOL score, is sensitive in differentiating subgroups. 相似文献

In estimating a linear measurement error model, extra information is generally needed to identify the model. Here the authors show that the polynomial structural model with errors in the endogenous and exogenous variables can be identified without any extra information if the degree is greater than one. They also show that a weighted least squares approach for the estimation of the parameters in the model leads to the same estimates as the solutions of a system of estimating equations. 相似文献

There is a worldwide trend towards increased collaboration in child protection practice which is primarily driven by researchers and policy makers. This sees child protection workers with the task of finding ways to implement the policy and build partnerships with the families they work with. The Signs of Safety approach to child protection casework, which was developed by the authors in conjunction with child protection workers in Western Australia, is designed as a practical method to foster a cooperative relationship between workers and families. This approach draws extensively on the ideas and experience of ‘brief therapy’ and is designed to be used in child protection practice from the intake and investigation stages through to case closure. This paper presents the different practice elements of the approach, the thinking that informs it as well as its application to assessment and case planning. Some case material describing the application of the approach is also presented. © 1997 John Wiley & Sons, Ltd. 相似文献

Objectives
Research suggests targeted exercise is important for people living with dementia, especially those living in residential care. The aim of this review was to collect and synthesize evidence on the known barriers and facilitators to adherence to group exercise of institutionalized older people living with dementia.Methods
We searched all available electronic databases. Additionally, we searched trial registries (clinicaltrial.gov, and WHO ICTRP) for ongoing studies. We searched for and included papers from January 1990 until September 2017 in any language. We included randomized, non-randomized trials. Studies were not eligible if participants were either healthy older people or people suffering from dementia but not living in an institution. Studies were also excluded if they were not focused on barriers and facilitators to adherence to group exercise.Results
Using narrative analysis, we identified the following themes for barriers: bio-medical reasons and mental wellbeing and physical ability, relationships dynamics, and socioeconomic reasons. The facilitators were grouped under the following thematic frames: bio-medical benefits and benefits related to physical ability, feelings and emotions and confidence improvements, therapist and group relationships dynamics and activity related reasons.Conclusions
We conclude that institutionalized older people living with dementia, even those who are physically frail, incontinent and/or have mild dementia can demonstrate certain level of exercise adherence, and therefore can respond positively to exercise programs. Tailored, individually-adjusted and supported physical activity, led by a knowledgeable, engaging and well communicating therapist/facilitator improves the adherence to group exercise interventions of institutionalized older people living with dementia.329.
