Mar-Sep 2015 (Mixed Methods Study)
CSK supported data collection activities for a mixed methods study under JHU titled “Assessing the Quality of Counselling and In-service Communication Related to Voluntary Medical Male Circumcision (VMMC) Services for Adolescents” in three regions of Tanzania. Data collection for this study were implemented in 2 phases and included focus group discussions (FGDs), in-depth interviews (IDIs), key informant interviews (KIIs), individual survey interviews (SIs), and on-site observations (OB). Phase I comprised of qualitative data collection activities while phase II involved quantitative data collection activities. During phase I, CSK team conducted a total of 201 qualitative interviews, including: 1) 53 FGDs with circumcised and non-circumcised male adolescents aged 13-19 years, 2) 32 FGDs with female adolescents age 16019, 3) 36 IDIs among male adolescents who have received VMMC services, 4) 17 KIIs with VMMC counselors and managers, and 5) 63 FGDs with parents of adolescents.
The quantitative component (phase II of the study) consisted of 2 rounds of survey interviews (SIs) with male adolescents (ages 10-19): first round was done just prior to circumcision and 2nd round 48 hours after the male adolescent had undergone VMMC procedure. The second round also involved video recordings of the entire process of VMMC counselling among a few selected adolescents as part of observations (video recording was used instead of having an observer in the room to allow for privacy and freedom). A total of 540 adolescents participated in the pre-procedure interviews and 498 (92.2%) participated in the post-procedure interviews; among these, 20 were video recorded during their entire counselling sessions.
Data Management Services
Along with data collection services, CSK also offers data management support, including 1) transcription and translation of qualitative data materials, 2) entry and/or cleaning of quantitative data materials, 3) coding and analysis of qualitative data, and 4) analysis of quantitative data. We have staff who are well-trained and mentored in managing both qualitative and quantitative data as well as quality assurance systems that ensure that our clients receive high-quality data.
Quantitative Data Management
CSK uses SPSS software for quantitative data analysis; however, we have supported data management using other data management software such as Stata based on our client preferences.
Depending on our clients’ preferences, we can share final quantitative datasets in any format (SPSS, Stata, excel etc.) along with the data dictionary.
Qualitative Data Management
CSK uses Atlas ti for coding and analyzing qualitative data materials, however, we have supported qualitative data management activities using other data management software such as MAXQDA secondary to our client’s preferences.
When CSK supports coding and analysis of qualitative data materials, we also share analysis outputs under all codes in the codebook from the query tool. For activities that CSK has produced qualitative reports, the latter has facilitated our clients to double-check what is coming out of the qualitative interviews under various codes vs. what is written in the report without having to run the queries themselves.
CSK has a good reputation in producing exceptionally high-quality qualitative transcripts and coded data materials.
Our transcription procedures for qualitative interviews involve several stages described below to ensure the high quality of final transcripts:
Our transcribers undergo additional training specific to every activity. The study-specific training is aimed at ensuring that the transcribers/translators have a good understanding of the aims and objectives of the study as well as the questions asked, and terminologies used.
The key terms used under each study and their correct translations are discussed among the team members to maximize consistency during transcriptions/translations.
Transcripts submitted by transcribers are reviewed by members of the transcription team who are trained as reviewers. These verify all the transcripts against their corresponding audios to ensure that the transcriptions and translations are accurate. Transcriptions not meeting minimal quality standards are returned to transcribers and contracts of transcribers who repeatedly submit transcripts that do not meet CSK’s minimal quality standards are terminated.
Our Qualitative data coding procedures involve the following steps:
The coding process begins by developing a preliminary codebook that comprises pre-set codes mainly derived from questions in the data collection tools as well as one or two transcripts coded manually. The preliminary codebook is shared with the client for their inputs.
Upon receiving and incorporating the client’s feedback, the preliminary codebook is then piloted on a few transcripts under each respondent category i.e. for each respondent category, coders code a similar transcript and compare the assigned codes under similar text segments.
Above is followed by resolving any disagreements, refining or merging the preset codes, and/or proposing new codes. This process is repeated with different transcripts under the same respondent category until when there are minimal or no disagreements in the application of codes among all coders, at which stage the codebook is deemed ready for use to code transcripts under the corresponding respondent category.
The codebook is piloted for each new respondent category to ensure that the existing codes also work for the new respondent category and where discrepancies are noted, appropriate adjustments are made to the codebook prior to using it for the new respondent category.
