Why is validating research important




















Test values range from 0 to 1. If you have a value lower than 0. If it does, you may want to consider deleting the question from the survey. Like PCA, CA can be complex and most effectively completed with help from an expert in the field of survey analysis.

If major changes were made, especially if you removed a substantial amount of questions, another pilot test and round of PCA and CA is probably in order. Validating your survey questions is an essential process that helps to ensure your survey is truly a dependable one. You may also include your validation methods when you report on the results of your survey. Validating your survey not only fortifies its dependability, but it also adds a layer of quality and professionalism to your final product.

Consumer Technology. Consumer Goods. Our guidance for those dimensions focuses on how to revise pro-WEAI modules and questions to better capture the experiences of women. Overall, the IRT analysis was useful for making recommendations for instrument improvement. We hope that these methods will become more routine in applied research on measuring empowerment.

Heckert: These results have given us lots of food for thought about how to strengthen the WEAI instruments moving forward. One takeaway is that we may need to revisit how response options are worded to make sure they are meaningful. Another is that we need to think more carefully about non-response and skip patterns.

Who is not responding and why? This is particularly important with regard to the questions we ask about income-generating activities. Third, we have built a stronger theoretical framework of how pro-WEAI maps to different theoretical ideas of empowerment, specifically intrinsic, instrumental, and collective agency. We need to develop more measures of collective agency, for example, and be more selective about measures of instrumental agency, where we already have multiple indicators.

Yount: I am very excited about the possibility of a collaborative study to develop a shorter, more streamlined WEAI for national monitoring. First, the individual ratings noted on the tool in advance of the focus group discussions were extracted. The returned tools and in some instances, when the individual forms were not returned to us, the transcript provided a record of these individual ratings.

Second, the consensus ratings for each item on the tool were identified from either a written record of the consensus scores or the transcript. Of the 32 focus groups, two groups total of six participants deliberately received a version of the tool that did not include the rating scale i.

Further the consensus scores of those who participated from the government sector were excluded from bivariate analysis due to small numbers of participants six and groups two for this sector. Thus, quantitative results for individuals are based on information from 30 focus groups, and results for consensus scores are based on information from 28 focus groups.

The variable for individual scores was coded as 'missing' for those individuals who did not return their tool or provide their ratings on their returned tools. The same consensus score for a questionnaire item was assigned for each member of that focus group. For some items, group members chose not to reach a consensus score. In these instances, the variable for consensus score was coded as 'missing'. In other instances, groups arrived at a consensus by assigning a score in-between ratings on the Likert scale.

Thus, for example, some of the final consensus scores were 1. The consensus score was used for the focus group level of analysis. The range, mean, and standard deviation for each item on the individually completed and consensus-derived scores were computed to assess response patterns. Non-parametric statistics Kruskal Wallis test were used to compare the differences between higher- versus lower-end research use organizations for individual and consensus scores.

During recruitment it was discovered that a Canadian Council on Health Services Accreditation process was occurring in the long-term care sector. Consequently, many long-term care organizations were unable to participate in the study. Other reasons for refusing to participate, that were common to all sectors, included lack of time, staff involvement in other research, and a perception that the project was not relevant to their organization e.

A total of individuals participated in the 32 focus groups. In total, 77 participants returned their individually completed tools to us, six participants had used a version of the tool without scales, and 59 did not return their tools or did not provide their ratings on their returned tools. The tool data was complete i. The items with the largest number of missing responses were for items 'evaluate the reliability of specific research by identifying related evidence and comparing methods and results' and 4.

Individual participants used the full range of response options one to four for all items on the questionnaire. Average scores ranged from 1. In comparison with individual responses, a truncated set of scoring options were often used by the group in arriving at consensus scores.

For 15 of the 27 questionnaire items, consensus scores had a range of two i. Consensus scores were missing for a number of reasons: the data were not extractable from transcripts in those cases where not recorded, the group chose not to give a consensus score to a particular item; or the group ran out of time and had no opportunity to discuss consensus scores for a particular item. In general, groups spent much more time discussing the first section of the questionnaire, and then quickly moved through the last two or three sections.

These differences were statistically significant for 13 of the 27 items individually rated, and for five of the 27 items rated by consensus. No consensus scores were significantly different between the two groups for sections three 'adapt research' or four 'apply research'. Practically every single group described the lack of time they had in their workdays to access, read, and incorporate research into their tasks and decision-making the general tone was not defensive but rather matter-of-fact.

When probed, focus groups participants mentioned that while not everyone had the skills to access research some participants were not sure they had the ability to even identify their research needs, or their researchable questions , there were some highly skilled people in an organization who were available to access research.

Furthermore, there was an awareness of the research being available via internal databases and subscriptions. These things just can't be bought on that sort of money' FG Another issue was trying to access those particular individuals or programs with the skills to help with retrieving and interpreting the research. Accomplishing this often required a formal request. The participants also noted that the informal networks that they or their departments have with external, university-based researchers were very important.

They saw this source as an effective way to find out about the literature in an area, about what the current position on an issue was, and what was seen as best practice. Participants identified a general lack of skills around assessing the research. Those organizations that had individuals with the research transfer skills suggested that more mentoring needed to occur to help increase the skill base. Also, there was a suggestion to remind employees that using research is simply part of their job, or to make it an integral part of what is expected from the staff coming into the system i.

One group discussed the fear that some may have in admitting that they lack the skill set required for using research, as described by one participant: 'I think we also have a fair number of people who are afraid to admit that they don't know how to look at and figure out if something is good science or not' FG Focus group discussions revealed an even greater difficulty with adapting and applying the research.

That is, there was issue with contextualizing the research findings, 'It is difficult [for] organizations at the grass roots to determine sometimes what stuff is relevant, which parts are relevant to what we are doing on a day-to-day basis' FG Participants were split about whether they were able to adapt research well.

Some described organizational pockets that seemed to do a better job than others. Research was not being adapted, however, on a regular basis. In many cases, the roadblock was having a stakeholder partner accept the evidence. Participants described how many factors played a role in decision-making, as illustrated in this participant comment: 'It's not that we doubt the evidence.

It's that all those other factors, and I guess that's where In terms of unique findings from the government sector, one participant suggested that senior bureaucrats do not value research and another said, 'policies are often out of sync with political dynamics' FG 3.

Consequently, participants did not feel that research was a high priority from the higher levels in the organization. Even though the opportunities were there — e.

Various barriers were identified to using research in government. One of the prominent barriers was the idea that the lack of application might be due to the focus of the research available. It was thought that much of the current research did not address operational or practice issues, which would be of interest to government decision-making.

The prevailing mood of the two focus groups in the government sector was that they did not find the tool useful. What was unique about the long-term care sector was the perception that research use for decision-making might be occurring at the management level.

In particular, participants talked about being 'handed down' best practices. On the other hand, there were occasions, participants noted, when management requested research from the lower levels. This was described as decision-makers wanting the 'right' information, the 'nitty-gritty'. Decision-makers wanted the research to help them put out fires. These groups identified a bit of trouble with the research terminology.

The concept of adapting the research was the easiest for them to understand; many groups stated that they came to consensus faster at this point. As stated by one participant, ' And personally I feel more capable of doing that' FG NGOs noted that the tool seemed to be geared to a more formal type of organization. Furthermore, the tool was focused on management and policy research, not the clinical practice research and the health policy economics issues that were of more central interest to them.

Nevertheless, there was a strong feeling among these participants that the tool generated a lot of useful discussion because it raised awareness of what to consider in using research. Participants from community-based organizations said that the discussion helped them to understand where the organization was placed with respect to research, because too often one only thinks about one's own immediate environment.

This led to the suggestion that future participants could be asked to link the tool to their business or strategic plan, and that this might invoke further discussion.

Participants had difficulty differentiating between their own team, department, or the corporation as a whole. There was also some trouble with the apply section of the tool because it was seen as more relevant at the decision-makers level, and participants were not privy to the conversations at this level. The tool demonstrated good usability and strong response variability in long term care, non-governmental, and community-based organizations.

This suggests that the tool is tapping into a set of skills and resources of relevance to research use. Moreover, while the average scores assigned by participants should not be generalized to other organizations in these sectors, the differences between higher-end and lower-end research use organizations on both individual and consensus scores — significant differences for nearly half of the individually scored items and consistently higher scores for 25 of 27 consensus items for higher-end research users — do suggest that this tool has adequate discriminant validity.

Time spent on the different sections of the tool varied considerably with the least amount of time and effort expended on the last two sections during the consensus process.
