Ranjit K. Singh<a href="https://sciences.social/@GESIS" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@GESIS</a> Thanks for sharing the talk! Here is the Question-Link R-Package and an in depth tutorial on using it: <a href="https://matroth.github.io/questionlink/index.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://matroth.github.io/questionlink/index.html</a>And please note that we also offer consultations regarding harmonization techniques (and other survey method topics). <a href="https://www.gesis.org/en/consulting/survey-methods-consulting" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.gesis.org/en/consulting/survey-methods-consulting</a><a href="https://fediscience.org/tags/surveymethods" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#surveymethods</a> <a href="https://fediscience.org/tags/harmonization" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#harmonization</a> <a href="https://fediscience.org/tags/rstats" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rstats</a>

Ranjit K. SinghMatthias Roth (<a href="https://mastodon.social/@rothm" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@rothm</a>) and I published a new paper on survey data harmonization."One harmonization fits all? – Impact of missing population invariance on harmonization error when harmonizing social science survey questions with equating"The paper again corroborates that observed score equating outperforms linear stretching on average. However, it also shows that it is better to derive a harmonization solution for single-item measures from a sample that is drawn from a similar population to the population you are interested in researching.<a href="https://doi.org/10.1080/13645579.2025.2481112" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://doi.org/10.1080/13645579.2025.2481112</a><a href="https://fediscience.org/tags/surveyresearch" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#surveyresearch</a> <a href="https://fediscience.org/tags/surveymethods" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#surveymethods</a> <a href="https://fediscience.org/tags/harmonization" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#harmonization</a>

Ranjit K. SinghIn a new paper, I simulate the consequences of combining survey data without proper harmonization techniques. I demonstrate that there is a plausible risk of biased correlative analyses based on the integrated data, if we do not harmonize measurement units across different survey sources and instruments first.<a href="https://fediscience.org/tags/surveyresearch" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#surveyresearch</a> <a href="https://fediscience.org/tags/surveymethods" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#surveymethods</a> <a href="https://fediscience.org/tags/harmonization" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#harmonization</a> <a href="https://doi.org/10.5964/miss.11217" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://doi.org/10.5964/miss.11217</a>

Ranjit K. SinghTogether with Cornelia Neuert and Tenko Raykov, I looked into "Assessing conceptual comparability of single-item survey instruments with a mixed-methods approach". Innovations are using a confirmatory factor analysis on a collection of single item instruments and comparing it with qualitative findings from probing questions.To illustrate the approach, we assessed the comparability of social (dis-)trust questions.<a href="https://fediscience.org/tags/surveyresearch" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#surveyresearch</a> <a href="https://fediscience.org/tags/harmonization" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#harmonization</a> <a href="https://doi.org/10.1007/s11135-023-01801-w" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://doi.org/10.1007/s11135-023-01801-w</a>

Ranjit K. SinghMy paper "Harmonizing single-question instruments for latent constructs with equating using political interest as an example" was just published in Survey Research Methods: <a href="https://doi.org/10.18148/srm/2022.v16i3.7916" rel="nofollow noopener noreferrer" target="_blank">https://doi.org/10.18148/srm/2022.v16i3.7916</a> 🎉 <a href="https://fediscience.org/tags/surveymethods" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#surveymethods</a> <a href="https://fediscience.org/tags/harmonization" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#harmonization</a>
